求一篇关于Language learning的英语文章

"Learning a language is easy. Even a child can do it!"Most adults who are learning a second language would disagree with this statement. For them, learning a language is a very difficult task. They need hundreds of hours of study and practice, and even this will no guarantee success for every adult language learner.Language learning is different from other kinds of learning. Some people who are very intelligent and successful in their fields find it difficult to succeed in language learning. Conversely, some people who are successful language learners find it difficult to succeed in other fields.Language teachers often offer advice to language learners: "Read as much as you can in the new language." "Practice speaking the language every day." "Live with people who speak the language." "Don"t translate - try to think in the new language." "Learn as a child would learn; play with the language."But what does a successful language learner do? Language learning research shows that successful language learners are similar in many ways.First of all, successful language learners are independent learners. They do not depend on the book or the teacher; they discover their own way to learn the language, Instead of waiting for the teacher to explain, they try to find the patterns and the rules for themselves. They are good guessers who look for clues and form their own conclusions. When they guess wrong, they guess again. They try to learn from their mistakes.Successful language learning is active learning. Therefore, Successful learners do not wait for a chance to use the language; they look for such a chance. They find people who speak the language and they ask these people to correct them when they make a mistake. They will try anything to communicate. They are not afraid to repeat what they hear or to say strange things; they are willing to make mistakes and try again. When communication is difficult, they can accept information what is inexact or incomplete. It is more important for them to learn to think in the language than to know the meaning of very word.Finally, successful language learners are learners with a purpose. They want to learn the language because they are interested in the language and the people who speak it. It is necessary for them to learn the language in order to communicate with these people and to learn from them. They find it easy to practice using the language regularly because they want to learn with it.What kind of language learner are you? If you are a successful language learner, you have probably been learning independently, actively, and purposefully. On the other hand, if your language learning has been less than successful, you might do well to try some of the techniques outlined above.

求一篇英语作文 题目为My language learning 不少于100个词 我想表达的有通过看电视等方式学习外语~~~

Every person has some language learning experience unforgettable weather it is horrible or enjoyable. People could have overcome barriers, eventually enjoyed the result, or suffered and ended up with nothing. One way or the other! I like to share my language learning experience with you, which has the combination of either ways.My language learning experience started with fun speaking different dialects at an early age. When I was one year old my parents sent me to live with my grandparents in their hometown Wuhan, in southern-central China. When I returned to live with my parents one year later I spoke Wuhan dialect.My parents lived in a northern city in Shandong province. I went to daycare everyday and very soon I picked up the local dialect. I also learned how to speak mandarin by listening to the radio and from many of my parents" friends and colleagues. It was so natural that I spoke Wuhan dialect with my parents, Shandong dialect with other children in daycare and then switched to Mandarin whenever needed.Time flew! A few years later when I was attending secondary school, I learned my first foreign language – English. Though we (people my age and I) were trained well in reading and writing English, we did not have much training in listening and speaking English. It was only in my university years that I started to have some training in listening and starting to practice spoken English between friends.In my last year of university I picked up my second foreign language for fun. I learned some Russian. Unfortunately because I never used it after I learned it I lost it all. Now all I know is a few words and how to say goodbye –до свидания!On the contrary, my English greatly improved after I moved to Canada. I had to listen to it everyday, everywhere. I had to understand not only English spoken with good pronunciation. I also had to understand English with all sorts of accents. Because Canada is a country of multi-culture! I had to speak it everyday and everywhere except at home. Wait! That is not completely true. Sometimes when my daughter speaks English in order to avoid Mandarin I can"t help responding in English.In the beginning I had to prepare what to say in my live situations beforehand. After a while I did not need to do that any more; in the beginning I could not understand half of English spoken in a movie, now I can enjoy movies in English with no problem. I have been enjoyed reading in English. I began by reading my daughter"s bed-time stories. Then I read books she borrowed from school library. Finally I find my own books from library since I could not catch up with my daughter"s speed and I do not always enjoy the taste of teens!I am now learning another language - French. With the well designed raining courses, I will not repeat my English leaning experience of unbalanced skills in listening and speaking abilities. I will learn reading, writing, listening and speaking skills at the same time. I will not repeat my Russian learning tragedy because I will speak French often.It is said that languages open doors for you. And I totally agree with it, because it is the essence of human communication! My language learning experience proves that it is true!自己改一下吧。

英语the secret to language learning

个人认为差别不大,就像汉语中的语言学习和学习语言,非要说区别,那不妨把它看成偏正短语,language learning更强调learning,learning language强调language。learning language和writing practice的结构不一样,虽然都是动名词+名词的形式,但是前者是动宾短语的动名词形式,learning相当于一个名词;后者的writing是动名词做形容词修饰practice,请注意区分。更简单的区分方法,去掉ing形式,learn language构成动宾搭配,而write practice不构成搭配。如果满意请采纳,谢谢

language learning是动名词吗

Learning a new language is fan.这一句中的Learn必须用动名词.因为在这里Learning a new language是一个动名词短语做主语,而is fun 作谓语.在英语中,如果一个动作做另一个动作的一个成分,这个动作常常用动名词或动词不定式表示,因为一个英语句子中只能有一个动词(或并列动词)作谓语.当然上句也可改为: It"s fun to learn a new language. To learn a new language is fun.

language learning 为什么用ing

这里的learning应该是名词形式,表示“语言学习”,所以加ing构成动名词 如:He is interested in language learning.

language learning是什么意思

language learning语言学习. 祝你学习愉快~希望能够帮到你!满意请采纳,谢谢!

口语课考试,how to learn foreign language,上台演讲

how to learn a foreign language well It is not difficult to learn a foreign language well as long as you get the keys. There are four most important things in learning a foreign language that are reading, writing, listening and speaking. Reading is a process of accumulating knowledge and words and from reading articles we get not only the main idea of the article but also the rules of writing. During reading we can feel the writing habits of local writers and make clear how the sentences are composed. And as you read on and on, you will become a fast reader that means you can read fast and you can get the meaning quickly. After having become a good reader, you can try to write on your own. To write doesn"t mean simply to use your pen, before you write you must get an idea of what you want to express or what you want to tell the reader. It is not easy to be an excellent writer but if you can make everybody understand your purpose you win. Moreover, writing can help training your thought. The same as talking to others, writing needs to choose proper words and organise them in a certain way, and during writing your thought can be improved. listening is also a nacessary part of learning a foreign language, besides, it is an important way of getting information. A lot of people like to listen to tapes, and this is a good way that I want to introduce to all of you. Don"t be dumb when learning a foreign language. When you communicate with other people you need to speak out. But some research show that most learners are afraid of opening their mouths especially at the very begining of their study. How to conquer it?Remember how did you write? Then just calm down and think and organise your sentences quietly and say it out just as you read from your mind. Easy? As a conclusion, to learn a foreign language is not difficult.Just try to be brave and self-confident and keep the above words in mind.

learn to enioy life 英语作文,150词汇

Often we"re told that we have to suffer now — give up what we want — in order to succeed later, that in order to save we must sacrifice. Give up instant gratification to get delayed gratification.But you can do both.For years, I was confused about this, as I read books and websites that sent me two different messages:  Pleasure later. The first message was that in order to be successful, in order to build wealth, you have to delay gratification. You can"t have instant gratification and be successful.Pleasure now. The second message was usually from other sources on Happiness, but sometimes from the same source: enjoy life now, while you can, because it"s short and you never know when your last day will come. Live every day like it"s your last. Trouble is, I agree with both messages. And if you read this site often, you"ll see that I send both messages: Live frugally and simply! But also enjoy life!  That"s because I"ve reconciled the two philosophies into one: Live life now and enjoy it to the fullest — without destroying your future. The key to doing that? Find ways to enjoy life completely, utterly, maximally … that don"t cost your future very much.Here are some tips for actually living that philosophy:  Find free or cheap pleasures. Frugality does not have to be boring or restrictive … if you use your imagination. Be creative and find ways to have fun — loads of it — without spending much money. Have a picnic at the park, go to the beach, do crafts, board games, fly a kite, make art, bake cookies … I could list a hundred things, and you could come up with a few hundred more. Make a list of simple pleasures, and enjoy them to the maximum. This is the key to the whole idea of enjoying life now without spending tomorrow"s dollar. See Savor the Little Things .Make simplifying fun. I"m a big fan of simplifying my life, from decluttering to creating a simple lifestyle in every way. And to me, this is great fun. I get rid of stuff (and possibly make money selling it) and have a blast doing it. That"s good math.  Rediscover what"s important. Oftentimes we spend tons of money, shopping, going out, watching movies, eating out … without really enjoying life. And when we stop to think about it, we never have time for the things we really want to do. Well, that"s probably because your life is filled with things that aren"t very important to you. Instead, step back and really think about what"s important to you. Then get rid of the other (expensive) stuff, and focus on what"s important. Listen to some stuff on my list: my wife and kids, other friends and family, reading, writing, exercising, volunteering, spending quiet time in contemplation. Guess how many of those things cost a lot of money? Read more here .

拯救大兵瑞恩里面有句台词,earn this,earn it,求翻译。

这句话经典之处就在于米勒上尉说得简洁意味又深远,earn原意赚取,个人理解this指瑞恩在米勒一行八人的奋斗下终于活了下来,it指瑞恩活着的机会,所以翻译过来才是别辜负大家。事实上瑞恩也将米勒上尉说的话牢记,从年轻到年迈。不是什么话语都能对译过来,N多个电影翻译版本翻译都是“好好活着,别辜负了大家”类似的话,如此翻译已经很到家了,但都没有英语原文那种意思

3分钟英语演讲稿文章 Learn to be a lady 谢谢~~

Learn to be a lady Eve SanJiaoLu middle school, the first one in wuchang couth boy, elegant girl comparison is announced, the school has more than 1100 students more than 30 "gentleman", "lady" get a certificate. "These students look beyond polite, learning, not afraid not to rob undisputable frustration, they are the most popular students." The university"s President ShenLianZhu said. According to introducing, this school shout out make students last year "the gentleman", "lady" slogan, and special offers a door, school-based curriculum in the classroom training students" "gentleman", "lady" temperament, this also is in social caused considerable controversy. In the school this course pushing a year later, schools have the first campus "gentleman", "lady" list.The students told reporters that the first "gentleman", "lady" is produced in the school. Students auditions Senior high school girls, said the LvJie boys and girls was elected the sense that gives a person is very kind, they humble but particularly enthusiastic, popularity was very good, "elegant girl talk softly, fine gas, very quiet way, let a person envy." Why get elected elegance boy?

In fact, our class boys are all very gentleman." It is reported, XuHao elected, their girls threw full-fare. In other people"s eyes, today"s high school students original, personality hobby. But on the sample investigation shows that high school students to be elegant "gentleman", "lady" more towns, eager to become a part of that popular. Now, ShenLianZhu told reporters after the high school students, and is more than 90 million only-child children, parents are afraid of frustration, everywhere requiring children avoid colliosion more difficultly, nor eat no deficit. So this generation of children give a person selfish, not to know self-effacing sense. But in creating "gentleman", "lady" in the process, he found humility comity such virtues, never goes out of style, and know the people come into society after comity, easier to integrate, their own competitiveness is subsequently ascension.

Make money and Earn money 的英语作文

Money is regarded by some people as the most importent thing in life. It is even regarded as the symbol of wealth and social position. For example, with plenty of money a man can do whatever he wants to. He can afford expensive cars and luxurious houses, and he can travel around the world and visit as many interesting places as he wants to. In their eyes, money is everything in life.In my opinion, money can both benefit people and do harm to them. On the one hand, we can"t deny that money is useful. We need money to buy food, buy a house or pay our education cost. Money can make us live more comfortably. For example, with more money, we can help others and take part in more social activities and receive a good education, thus increasing our knowledge and developing our skills. On the other hand, some people try to get money by dishonest means, for example, they often cheat and gemble, even rob and kill people. Sooner or later, they will be punished by the law. Money can bring them nothing but misery.In addition, money can not buy everything, For instance, no matter how much money one hast he can not buy good health, happiness or friendship, Although money is useful in many ways, there are still a lot of things that money can"t buy in the world. In addition, money can also do harm to us. If a person really thinks of money as everything and pays his attention only to money, he will lose his friends, or even the care and warmth from his family. Thus, it brings him only loneliness.

guess this has a lot to do with your current English knowledge, including pronunciation, vocabulary, grammar, and understanding of English. I do not agree with learning a language in a short time. How short? One week? one month? It is hard to say.    If you are really interested in English, you will surely make progress if you keep working on it; if you are not interested and don"t persist with it at all, it will become really difficult. To speak fluent English is not too difficult provided you practice enough with enthusiasm; but to speak perfect English, or, in other word, as well as you speak Chinese, will be very, very challenging.    Frankly, I think I speak English well, meaning I can express myself clearly and accurately in English. But I am not at all satsified, as each time I speak I feel that it is not a language of my own, that it is different from I speak Chinese!     Therefore, I am a little frustrated. But I won"t give up trying. I wish that I could really feel that I am using this language as I use Chinese some day. How much longer time I need before I achieve this goal is yet to be found out.     Last, let me reassure you that it is not difficult to speak English well if you keep practicing! Easier said than done, not many people can KEEP going, and there are another major group of people who are always struggling with opening up their mouth to utter their first English sentence. Once they succeed, they will get over the first stumbling block, and it is not too long before they can surprise themselves!

用sklearn进行降维的七种方法

在实际的应用中,有时候我们会遇到数据的维度太少,我们需要新生成新的维度,可以用我们之前的分享( 如何自动化进行特征工程 );有时候维度太多,这时候我们就需要降维了。降维的方法有许多,我们这里介绍了sklearn中介绍的7种,供大家学习和收藏。 主成分分析(PCA)用于将多维的数据集分解为一组具有最大方差的连续正交分量。在sklearn这个包中,PCA是一个transformer对象,使用fit方法可以选择前n个主成分,并且用于投射到新的数据中。 PCA有两种实现方式,一种是特征值分解去实现,一种是奇异值分解去实现。特征值分解是一个提取矩阵特征很不错的方法,但是它只是对方阵而言的,如果不使用SVD,PCA只会寻找每个特征的中心,但并不会对数据进行缩放(scaled)。使用参数whiten=True ,可以将数据投射到奇异空间中,并且将每个组分缩放到方差为1,这个对于后续分析中,假设每个特征是isotropy 是很有帮助的,例如SVM和Kmeans聚类。 PCA不仅仅是对高维数据进行降维,更重要的是经过降维去除了噪声,发现了数据中的模式。PCA把原先的n个特征用数目更少的m个特征取代,新特征是旧特征的线性组合,这些线性组合最大化样本方差,尽量使新的m个特征互不相关。 SVD是一种矩阵分解法,把一个大矩阵分解成易于处理的形式,这种形式可能是两个或多个矩阵的乘积。 参数 例子2:获取每个主成分与特征的关系 PCA虽然很有用,但是需要将数据全部都存入内存,因此当当要分解的数据集太大,会导致内存很大。这时候,增量主成分分析(IPCA)通常用作主成分分析(PCA)的替代,可以通过部分计算的方式,获得跟PCA一样的结果。 IPCA使用与输入数据样本数无关的内存量为输入数据建立低秩近似。它仍然依赖于输入数据功能,但更改批量大小可以控制内存使用量。 该函数,增加了一个batch_size的参数,用来控制批次,其余都一样,至此不再赘述。 实例 对于大型矩阵的分解,我们往往会想到用SVD算法。然而当矩阵的维数与奇异值个数k上升到一定程度时,SVD分解法往往因为内存溢出而失败。因此,Randomized SVD算法,相比于SVD,它更能适应大型矩阵分解的要求,且速度更快。 此外,在某些场景下,我们期望丢掉某些lower sigular values,来达到减少噪音,保留尽可能多的方差,从而达到更好的预测效果。比如人脸的识别,如果是64X64的像素,那么整个维度有4096个。我们利用这个方法,可以保留重要的维度,从而利于后续的分析。 使用 svd_solver="randomized" 可以实现随机化的SVD,来去掉部分的奇异矩阵。 主成分分析(Principal Components Analysis, PCA)适用于数据的线性降维。而核主成分分析(Kernel PCA,KPCA)可实现数据的非线性降维,用于处理线性不可分的数据集。kernel的选择有 {"linear", "poly", "rbf", "sigmoid", "cosine", "precomputed"},默认是"linear"。 详细说明见官方说明,与普通的PCA差不多。 SparsePCA 期望找到一组可以最优地重构数据的稀疏主成分。稀疏性的大小由参数alpha给出的L1惩罚系数来控制。Mini-batch sparse PCA是sparsePCA的变种,提高了速度,但是降低了精度。 主成分分析(PCA)的缺点是,该方法提取的成分是一种密集表达式,即用原始变量的线性组合表示时,它们的系数是非零的。这可能会使解释模型变得困难。在许多情况下,真实的基础分量可以更自然地想象为稀疏向量;例如,在人脸识别中,主成分会只包含部分的图像,映射到人脸的某些部分。稀疏主成分产生了一种更简洁的、可解释的表示,清楚地强调是哪些原始特征导致了样本之间的差异。 通过调节alpha来调整惩罚度,alpha越大,越导致许多系数为0。 TruncatedSVD是普通SVD的一个变种,只计算用户指定的前K个奇异值。TSVD通常用于语义分析中,是LSA的其中的一部分,可以解决一词多义和一义多词的问题。 LSA潜在语义分析的目的,就是要找出词(terms)在文档和查询中真正的含义,也就是潜在语义,从而解决上节所描述的问题。具体说来就是对一个大型的文档集合使用一个合理的维度建模,并将词和文档都表示到该空间,比如有2000个文档,包含7000个索引词,LSA使用一个维度为100的向量空间将文档和词表示到该空间,进而在该空间进行信息检索。而将文档表示到此空间的过程就是SVD奇异值分解和降维的过程。降维是LSA分析中最重要的一步,通过降维,去除了文档中的“噪音”,也就是无关信息(比如词的误用或不相关的词偶尔出现在一起),语义结构逐渐呈现。相比传统向量空间,潜在语义空间的维度更小,语义关系更明确。 使用例子如下: 用事先预定义好的字典来对矩阵进行稀疏化编码,达到降维和简化的目的。就像人类的所有语言都是由单词组成一样,因此使用已知的词典可以减少维度;其次,稀疏化可以减少计算的成本,让后续的计算更快。 这个对象没有fit的方法,transformation方法会将数据表示为尽可能少的字典原子的线性组合。可以用transform_method来控制初始化参数,有以下几种: 使用的函数为sklearn.decomposition.DictionaryLearning,会找到一个可以将fitted data足够好稀疏化的字典。 将数据表示为一个overcomplete的字典这个过程,同大脑处理数据的过程类似。这个方法在图像补丁的字典学习已被证明在诸如图像完成、修复和去噪以及监督识别任务的图像处理任务中给出良好的结果。 使用函数为sklearn.decomposition.MiniBatchDictionaryLearning,是一种快速的,但是精确度降低的版本,适应于大数据集合。 默认情况下,MiniBatchDictionaryLearning将数据分成小批量,并通过在指定次数的迭代中循环使用小批量,以在线方式进行优化。但是,目前它没有退出迭代的停止条件。也可以用partial_fit来实现小批次的fit。 从变量中提取共性因子。 因子分析要求原有变量间具有较强的相关性,否则,因子分析无法提取变量间的共性特征,如果相关系数小于0.3,则变量间的共线性较小,不适合因子分析;因子分析得到因子和原变量的关系,因此能够对因子进行解释。 因子分析可以产生与 PCA 相似的特征(载荷矩阵的列)。不过,不能对这些特征做出任何一般性的说明(例如他们是否正交)。 使用的函数为sklearn.decomposition.FactorAnalysis。 使用的函数为sklearn.decomposition.FastICA,ICA可以提取出一系列的主成分,彼此最大的独立。因此,ICA一般不用于降维,而用于区分叠加信号。ICA不考虑noise,为了使模型正确,必须使用whitening,可以使用whiten这个参数。 ICA 通常用于分离混合信号(称为盲源分离的问题),也可以作为一种非线性降维方法,可以找到具有一些稀疏性的特征。 主成分分析假设源信号间彼此非相关,独立成分分析假设源信号间彼此独立。 主成分分析认为主元之间彼此正交,样本呈高斯分布;独立成分分析则不要求样本呈高斯分布。 非负矩阵分解,顾名思义就是,将非负的大矩阵分解成两个非负的小矩阵。在数据矩阵不包含负值的情况下,应用NMF而不是PCA或其变体。 NMF可以产生可以代表数据的主成分,从而可以来解释整个模型。 参数init,可以用来选择初始化的方法,不同的方法对结果会有不同的表现。 在PCA处理中,假使将特征降维为600个,那么降维后的每个人脸都包含了600个特征(所以我们看到降维后的人脸有种“伏地魔”的感觉 ,这是因为降维处理相当于删去了部分细节特征,导致一部分信息丢失,在图片中最直观的体现就是变模糊)。而在NMF的处理中,这1000个特征相当于是被分离了。相当于,一张人脸是由鼻子、耳朵等这些独立的特征叠加出来的。 LDA是文档主题生成模型,对离散数据集(如文本语料库)的集合的生成概率模型。它也是一个主题模型,用于从文档集合中发现抽象主题。LDA是一种非监督机器学习技术,可以用来识别大规模文档集(document collection)或语料库(corpus)中潜藏的主题信息。 sklearn.decomposition.LatentDirichletAllocation是用于进行LDA的函数。 1、 https://www.jianshu.com/p/1adef2d6dd88 2、 https://www.jianshu.com/p/e574e91070ad 3、 https://scikit-learn.org/stable/modules/decomposition.html#decompositions 4、 https://shankarmsy.github.io/posts/pca-sklearn.html 5、 https://mp.weixin.qq.com/s/Tl9ssjmGdeyNrNuIReo1aw 6、 https://www.cnblogs.com/eczhou/p/5433856.html 7、 https://scikit-learn.org/stable/auto_examples/applications/plot_face_recognition.html#sphx-glr-auto-examples-applications-plot-face-recognition-py 8、 https://blog.csdn.net/fkyyly/article/details/84665361 LSA(Latent semantic analysis) 9、 https://blog.csdn.net/fjssharpsword/article/details/74964127 10、 https://www.jianshu.com/p/e90900a3d03a

有关于“learn to say no "的英语作文。(50-100)词 。很急。。。。。

百度知道愿意为您解答难题!Learn to say “no” For most of us , saying “no” is very difficult. We don"t want to offend or disappoint people. As a result, we have to spend too much of our time and energy on doing things, which seriously interferes our work. But it requires a great time and energy for us to pursue our goal. In fact, not only do we have to devote most of our time but also our heart and soul. Therefore, even if a request is legitimate and important, sometimes we just have to say “no” in order to prevent too great a toll on our time. And it is possible to decline a request in ways that do not seem rude or unkind. Here are some nice ways to say “no”. You may pay a compliment as you say “no”. Take a university professor, Delores, for example, when someone calls asking him to serve on their board, and he knows that he just can"t do it. He often say, “ I"m so glad you thought of me. I am a big fan of your orgnization, but my schedule just won"t allow me to accept your invitation.” You may also decline in a positive way. For example, “That"s a good product, but it"s not something we can use at this time,” is a gentle way to say “no”. Buy yourself some time. Seldom do you have to give a yes or no answer on the spot. Even if you feel strongly that your answer will be no. Buy yourself sometime by saying “Let me think about it”, “Let me talk it over with my family” and so on. 望采纳
