文法检查 语法好的进 要过去式Now,his assassination have been finished for

没错

开着,形容词.

不用随便用yet直接替换but吧.有语法问题或者意义上的问题.我尽量按照你原来的思路修改,没有加太多修饰,请参考：
但我仍忘不了当我知道你正在做你喜欢的事的时候的快乐
But I still can't forget the happiness I feel when I know that you are doing what you really like.
有时我觉得你很远可又好像离我很近
Sometimes I feel that you are far away while sometimes you appear to be so close to me
有句话说"两点之间的距离仅仅是距离,别无其他"说的就好像我们
They say,"There's nothing but distance between the two points” just like we do.
但没关系 因为你给我的不只是勇气还有希望
But that's all right,because you have brought me not only the courage but also the hope.
我希望你在未来能很快乐而且要记得照顾自己
I hope and pray that you'll enjoy the happy life and remember to take good care of yourself.

你这是典型的中式英语,正式的搭配是 have some problems in doing sth.或是have some problems with sth.所以可以说I have some problems with my English.Is there any problem with my English?

如下：
E->0 E 1
E->ε

紫藤有它自己的开放

kalbi 牛肋骨的意思
How many steps is this kalbi at total?
Altogether six steps.
What is the best to eat with this kalbi
Eat with rice is the best

答:
一
1. S -> aS | ε
2. S -> aS | Sb | ab
二
设 有字符串序列 abc, 而字符串 abc 符合是文法S.
abc 有两种推导 ① S -> Ac, A -> bc
② S -> aB, B -> bc
有两语法树,二义文法
三
不好意思忘记了短语、直接短语和句柄
课本上应该有

B

你自己写的已经很好了!基本上都很正确,文法上也没有多大错误,只是最后几句更简洁、流畅,我试改如下：
My favorite fruit is watermelon.Watermelons are mainly produced in the central and southern parts of Taiwan.There are yellow and red watermelons.I like the red ones more because they are usually sweeter.Watermelon sometimes tastes like smoothie for its juiciness.Eating watermelon can always cool me down during the summer time.Of course,I like the watermelon juice as well.

是不是也可以理解为句子的语境?

Recently we had a lot of activities, such as "open house".
That day, every student had a good time. Its goal was to give the boys and girls a chance to make friends.

November 12th will be the final day of the "Campus Singer" competition. You will vote for the winner.
这样起码能拿得出去了,你打字错误太多,而且语法方面的小错也不少,不过,要坚持经常写,用不了一年,你的英语就会超过我的

void NumAnalyse(){

不对,把WAS 改成were

S→Qc︱c （1）
Q→Rb︱b （2）
R→Sa︱a （3）
将第1个式子带入第3个式子,再将第2个式子也带入,得

The development of industry cluster theory,from Weber's locational agglomeration experienced theory,Schumpeter's Innovation and industrial agglomeration theory,Hoover's optimal scale of industrial clustering theory to today's "industrial clusters" of Porteris,is becoming increasingly theoretically rich.Based on analysis of the formation of industrial clustering and its economic impact on forestry development,the following paper proposes a few applications of industrial clustering,aiming to promote sustainable development of forestry industries.
我大改了 帮你的语言改的proper&formal了很多

我认为是A,
Despite her great age, she was very graceful indeed
despite 介词后面只能接名词或名词性词组
这里 only 1 or 2 inches long 明显是个形容词词组
only 1 or 2 inches 修饰 long
介词后面不能只跟形容词的,需要改成Despite only 1 or 2 inches in length

说实话,真不愧是自己编写的句子啊,尤其是第3句 读起来很不顺畅,第三句建议改成which does he tell about what he wants

我觉得可以买初中的英文课本自学~~毕竟那是千千万万中学生实践过来的~~编排比较规范语法讲解也更为清晰而且循序渐进由浅入深.
英语的读音不如其他语言那么方便,不能直接拼读,它需要靠音标硬性记忆,因此读音的规律也不很明显.
至于要多久能聊天那要看个人花的时间及掌握能力了.若是之前没学过别的语言,这是第一门外语的话相对来说会花上比较长的时间,因为它与汉语相差甚远,需要相当的时间来适应.但如果真的下了功夫两年应该可以.
这期间你可以先慢慢听听VOA慢速英语,听不懂没关系先培养一些语感.平时也可以多看美剧,那里面对话都是非常地道的表达,对口语特别有帮助.
只要有决心有毅力,没有什么做不到的!

显然,这个是二义文法,所谓的二义文件就是一个结果,推导的过程可能有两个以上!
G[S] ->ibtSeS->ibt(ibtS)eS->ibtibtSeS
G[S]->ibtS->ibt(ibtSeS)->ibtibtSeS
到这里就可以推出相同结果,就算你再加上终结符,结果也是一样的.而推导的过程却不一样,很明显了吧,二义文法!

二义性是那些模棱两可的语句产生的,所以不能用算法消除 追问： 不是消除,是判断 回答： 那也没有判断的,只能自己判断,因为二义性它不是错误语句,不管怎样它都能运行 追问： 难道不存在一个分析树算法,判断是否有两种分析树? 回答： 说实话我真没有见过有这种算法

我想应该是具有的
比如说123
可以是D = DD D = (DD)D D = (12)3
也可以是 D = DD D = D(DD) D = 1(23)

是的,不然他就不是ll1了,你可以进左递归并或提取公因子,可以解决二义性

Hanson said that he would leave for London tomorrow.
Q2."We took the children to the park last week," they said.

as是一边...一边...的意思,动作大多是同时发出.
例：He thought of something else as he smoked.
while表示一段时间,强调两个动作必须同时发生,主从句都用成进行时,从邹德位于必须是延续性动词.while还可以引导让步状语从句,意为“虽然”,表示对比.
例：Don't make any noise while others are reading.
Tom is singing while Mary is dancing.
when可以表示一个片断时间,也可以表示一段时间.主局的动作可与从句动作同时发生（用进行时）,几乎同时发生,或不同时发生.
例：When I knocked at the door,Tom opened the door for me.

最有效的方法是画slr分析表,有移入-规约冲突,或者规约-规约冲突的就不是slr文法,没有冲突就是slr文法.简单的用follow集合是不能准确判断它是不是slr文法的

构造LR(1)自动机（没有需要合并的状态）：
没有状态存在冲突,因而是LALR(1)文法.
构造LR(0)自动机：
在状态I6,由于’a’∈FOLLOW(A),因而对于SLR(1)分析而言,存在移进-归约,所以这一文法不是SLR(1)文法.

满语天：abka 阿拂喀, 上天和日子不是一个词,上天一般也是abka,日子一般是inenggi.

在一定条件下,重复做n次试验,nA为n次试验中事件A发生的次数,如果随着n逐渐增大,频率nA/n逐渐稳定在某一数值p附近,则数值p称为事件A在该条件下发生的概率,记做P(A)=p.这个定义成为概率的统计定义.
P(A)=m/n,n表示该试验中所有可能出现的基本结果的总数目.m表示事件A包含的试验基本结果数.这种定义概率的方法称为概率的古典定义.

《寂静的春天》是一本引发了全世界环境保护事业的书,书中描述人类可能将面临一个没有鸟、蜜蜂和蝴蝶的世界.作者是美国海洋生物学家蕾切尔·卡逊,于1962年出版.这是这本不寻常的书,在世界范围内引起人们对野生动物的关注,唤起了人们的环境意识,这本书同时引发了公众对环境问题的注意,促使环境保护问题提到了各国政府面前,各种环境保护组织纷纷成立,从而促使联合国于1972年6月12日在斯德哥尔摩召开了“人类环境大会”,并由各国签署了“人类环境宣言”,开始了环境保护事业.
"Silent spring" is a cause of environmental protection enterprises around the world of books,the book describes the human could face a no birds,bees and butterflies world.The author is the U.S.Marine biologists Rachel Carson,was published in 1962.This is the unusual book,throughout the world to cause people to the attention of wild animals,arouse people's awareness of the environment,this book also sparked public to environmental problems,and to promote the environmental protection problems mentioned before governments,all kinds of environmental protection organization established in succession,so as to make the United Nations in June 12,1972 in Stockholm held a "human environment congress",and the countries signed the "human environment declaration",started the environmental protection industry.
蕾切尔·卡逊1907年5月27日生于宾夕法尼亚州泉溪镇,并在那儿度过童年.她1935年至1952年间供职于美国联邦政府所属的鱼类及野生生物调查所,这使她有机会接触到许多环境问题.在此期间,她曾写过一些有关海洋生态的著作,如《在海风下》,《海的边缘》和《环绕着我们的海洋》.这些著作使她获得了第一流作家的声誉.

通过算法对文法的每一产生式进行分析,如果存在复杂递归,则必是上下文无关文法,否则就是正则文法.
1、像A->Aa|ε这样的文法,虽然存在递归,但却是单一的自递归,可以通过有穷自动机表示和分析处理,所以是正则文法；
2、但是像E->E+T,T->id|(E)这样的文法显然非单一的自递归,而是存在复杂递归,自动机是无法表示和处理的,必然是上下文无关文法.
另外还请注意：
1、正则文法是上下文文法的子集,正则文法也属于上下文无法,但有的上下文文法不一定是正则文法；
2、同时再结合这两个的形式定义认真揣摩必定能悟出一二.

Gothic culture and the Gothic rock / metal music what "Gothic"? First, literally interpreted, it embraces the three significance, the first in the Gothic architectural style as Cathedral (cathedral), the biggest feature is the tall arched ceilings and structural beams and Tsim Sha Tsui; Second, in Gothic literature is used to describe those dark lonely places (such as abandoned Castle) to the background of a strange mystery adventure story; Third, also on behalf of a Gothic font and vocals of printing and writing style. The earliest "Gothic" this characters is based on the Renaissance period was used to distinguish the Middle Ages (Middle Ages,5~15 century) art style its the Exaggerative is from in had the Y2K 3 ～ 5 century aggression Italy and the dismantlement of the Roman Empire the German Gothic tribe, in the 15th century, Italy person with the revitalization of in ancient Rome culture of idea of thus whip up the splendid literature and movement, as Italy person to Gothic nation to destroy the Roman Empire during this period of history two lovers whose source is always difficult to-plussed when, therefore of order in connection with this period to targeting a specific audience sector, they will cast the Middle Ages the arts style titles for Gothic, as they were concerned means that the barbaric. Despite the original Gothic is the word carries with it a negative connotation, but in fact impressive and beautiful works of art have been created out at this time. 12 century, the construction of sophisticated technology, thus creating a lot of the birth of Gothic cathedral, it is the most famous Notre Dame Cathedral in Paris (Notre Dame). Of course, the Gothic style was not limited to construction, such as sculpture, glassware, jewelry and colorful tie is responsible and so on, are affected by such art from the 12th century to the early 16th century has ended. Gothic art in fact religion plays a very important role, regardless of the artist or sculptor, in that they would prefer to work on religious issues, themes and less interested in realism. About in the Year in 1800 around the latest arrival Romantic Movement (Romantic Movement), Gothic with the medieval culture is again being people's pro-have altered history textbooks to mislead the ideology able to to recover and Romanticism can be said to be For the Enlightenment Movement (the Enlightenment) rationalism (Rationalism) reactionary, perceptual, non-rational attitude is this the campaign centers in this period, Gothic started and darkness, singular, weird found in relation to, in fact grand romantic style the are many symbolic and subject matter and these Gothic the sub-culture of a rather similar, this period of some writers very keen on Description people's darkness, emptiness face, sexual paranoia, terror, a god themes are literary works were widely to use. In addition, in the visual arts, Romantic painters prefer the same dark, desolate landscape. In a symbol of Gothic novels is the most typical vampire (vampire), the works of Bram Stoker's classic "Dracula", and even joined the Vampire images in the book, for the development of the 19th century Gothic literature is entitled to the origins of vampires.
Time came to the 1980s, new Gothic movement started in Britain did the Gothic movement there might be considered on the previous Cyberpunk culture (Punk), a reactionary, no matter how, Gothic spirit started in music to demonstrate its influence, Gothic music the same preferences to encourage the darkness and emptiness face as a title, and of death also has a strong interest, the slow, sad and even terror are its music features, and vampires again become the theme of the best symbol. In addition to the musical performance of the Columbia mission groups in the visual artists showing dead aesthetics, such as a pale face painting, black clothes, or the British Zhebian 19th century Victorian-style clothing, and the ruins of medieval, Gothic-style buildings have been extensively applied. Gothic movement in the United Kingdom reached a peak in the mid-1980s, and most representative of the Orchestra of The Sisters of Mercy, The Mission and other Fields of the Nephilim. Musical styles, the music of this period was known as the British New Wave Gothic, adding in a lot of rock synthesizer (keyboard), and the above mentioned Gothic elements, even with electronic flavor. Wave and Gothic rock/New imported in the United States in the further development of industrial branches, known organizations such as Ministry and Nine Inch Nail; The other hand, Europe is even more flooding to electronic music. Although Gothic music in Europe towards more electronic music, but also a number of other deformation, but in fact Gothic metal music is brewing in the early 1990s, and finally in 1995 by the Norwegian Theater of Tragedy regiment's first album 80 of the same name metal era of Gothic atmosphere. But at the beginning of talks Gothic metal ago, we had to start with the destruction of metal (doom metal) came, doom metal is a very heavy, dark, slow, melancholy and sadness in the music form that was doom metal earliest origins can be traced to Black Sabbath's first album the same name, and the subsequent album, but really doom metal style set is from Sweden regiment Candlemass in 1986 published the album began. A lot of doom metal group in the late 1980s to the early 1990s when the birth of the famous British regiment My Dying Bride then more will be included in the preparation of the violin as a bleak future reference Orchestra sent doom metal pioneer.
And doom metal in the 1990s, many have begun the development of Theater of Tragedy is the first to doom metal and gothic rock from the inspired fusion of the gothic and then create a new school doom metal and T.O.T. Can be said to be a rejuvenation of the most important Gothic style hero once again, T.O.T. Gothic metal makes this wave of success from the Nordic spread quickly from the beginning. Theater of Tragedy several characteristics have become Thereafter Columbia mission metal basic elements, in particular, has become today the mainstream style of gothic death, such as mining death metal brutal men cavity (or even black metal Tsim roar black cavity) match Sophie beautiful women sounded the antiphonal singing form, it is precisely Israel romantic Gothic spirit of this contrast style but also a symbol of darkness (dead space and metal Le part) with a bright future, life and love (female sounded, piano and symphonic part) between confrontation. And T.O.T. Soprano lead singer Liv arms and the beauty of her singing did not know how much steel already conquered the hearts of men. But European countries because of cultural differences, making gothic metal is also developing even spread out in many different forms, apart from gothic doom, in the Netherlands from The Gathering has established himself as a gifted beautiful women sounded as lead singer and focus on spiritual feeling, the pure gothic metal, its lead singer Anneke van Giersbergen unsubstantial and muddied U.S. tone can be described as gothic metal sector perfect example later, in the other two the Dutch gothic metal Mission Within Temptation and After Forever, have to have timbre approximate Anneke of the nest and singing a saying, The Gathering of Dutch gothic metal shows the influence. The Gathering is a gradual change in the near future, however style metallic components has become increasingly short. In addition, the Nordic Orchestra further to be some black metal with elements of gothic Among become gothic black and renowned orchestras have the same from the Norwegian Tristania and The Sins Of Thy Beloved, etc. However, in fact, gothic in the Nordic development has been to gothic, doom, death, black integrated, and so difficult to categorize in a single style, such as Tristania Apart from the grand symphonic stature, or even using clean men cavity, black dead space plus opera female lead singer and choir chorus. Of course, the Nordic Music Orchestra has not only was it thought Sweden Therion will be to develop a distinctive orchestral instruments (synthesizer sound samples) and metal instruments of both symphonic opera metal, in its most recent concert are completely Opera Choir and professional men and women. In addition, Finland As Divine Grace Chen Jing elegant atmosphere gothic to go through the ups and prosperous world feel. Germany were developed in classical gothic folk kingdom come, Lacrimosa, Haggard, in addition to these groups synthesizer, but also for the actual music, classical flavor is very strong, as Lacrimosa directly with the London Symphony and the Orchestra includes members of Haggard's hand or even 18. Italian avant-garde in recent years to speed metal and symphonic metal gained bombs in the whole of Europe, but its Gothic metal in the development of not falling behind, Inner Shrine, the argument is a prime example, the former U.S. sorrow desolate atmosphere, which is filled with romantic and charming melodies. In addition, there are also some focus on the atmosphere created by the orchestra, filled with a sense of medieval Dunwich and Crown of Autumn, which Dunwich more use of musical instruments and medieval monks choir. Other European countries also have representation of the orchestra, such as Poland, Sirrah, the Even Song Hungary, Romania On Thorns I Lay, style are completely different. From the above introduced can understand, the Columbian the Independent Commission on the metal Lok has been a comprehensive development no longer confined to a single style, while Gothic is not just a rock, it is most of all a life attitude, Gothic is one which people can to flee reality and enter the illusion the world, a dark and romantic the world, Gothic the spirit of not only can manifested in music, can also in their attire artistically and literature, with a great number of lace. The clothes, symbol of a romantic Rose, graves, are connected with vampires, witches, ruins, Gothic's Cathedral so on, have all these are Gothic of symbols. Of course, purely from a musical point of view, the general preference of the strong metal fans directly, it may slow, focused atmosphere of Gothic metal play more difficult to accept, but if it gets to the root of this music to understand the background and send their wish has moods, appropriately adjust your own mind, he may realize that a different type of feeling and fun to listen to.

2.yet我觉得在此译为" 还“.yet有好几个意思,不同的意思的用法和句中位置不一样.
3.were没有放在句首,这仍然是一个完整的句子,只不过被一个插入语（we will not despair）打断了,插入语不影响本来的句子.were仍然接的是what
4.could放在句首很常见,这里像是一个反问句.
