China is the largest smartphone manufacturer in the world. Its domestic
demand for smartphones is surging as traditional mobile users switch to more
advanced handsets. But most of the new demand is not for the latest gadgets from
Apple or Samsung.
Apple's loss is Chinese brands' gain. Instead of an iphone, many choose
cheaper home-grown smartphones when they upgrade from feature phones.
"Xiaomi's price is good for average
consumers. I can accept the price. The quality is not bad either. Web streaming
is very fast. Thats why I'm getting one."said a consumer.
Lower prices, more geared to local needs. Millions of consumers like Mr Liu
have the same idea. That's why Apple's share of China's smartphone market was
halved in the second quarter--and the US tech giant is trying to catch up.

no idea...

第一题
因为sinx与x是等价无穷小,所以sin(x^2-1)用x^2-1替换,所以原式为x+1当 x趋近于1的极限
第二题
xsin(π/x)=sin(π/x)/(π/x)*π所以当x趋于无穷时得π
而)(π/x)sinx 相当于无穷小乘以有界函数,还是无穷小,0,所以结果π
第三题
变为[1+(x+e^x-1)]^1/(x+e^x-1)*(x+e^x-1)/x
其中[1+(x+e^x-1)]^1/(x+e^x-1)的极限是e
(x+e^x-1)/x的极限是2,利用e^x-1与x是等价无穷小,所以结果e^2

My past university
I want to talk about my past university—Shan Xi Da Tong University.It not only provided me
learning environment,but also provided me social practice platform.That is to
say,I am not only acquired basic knowledge but also learnt how to get along
well with others in four years’ university life .I missed these places mostly,
library,student union and my dormitory.I used to study in library because it’s
learning environment is very good and it has many kinds of books,but seats are
limited; I took part in the student union when I was a freshman.I made more
friends and actived in many extracurricular activities in union,but it often
took a lot of time; I like my dormitory best.I shared my happiness and sorrows
with my room-mates and I relaxed myself sufficiently in it.But the condition of
my dormitory is poor.Above all,University is my unforgettable place.
I spent most of my extra-study time in
library.Generally speaking,It is a good study place.Firstly,the atmosphere
of study is strong,but sometimes someone would receive and make calls,which
would impact others’ study.If it can provide a few of fountains,the library
would be perfect.Secondly,it has abundant of professional books,thus I can
access to needed information timely when I encountered problems in study.
Besides,there are also all kinds of magazine,so I can relax myself and expand
my vision when I was tired of studying.But the limited time of borrowed books is
short.Last but not least,the seats are limited,which disturbed me very much.
I had to go to the library line up very early just for seat.But the desks and
chairs are big enough,which gave me much space to think and study and reduced
the impact between students.The desks and chairs are tidy and comfortable.All
in all,I like our library very much.
I took part in the student union when I was
a freshman.I made many friends in union.I exchanged my idea with others.I
enhanced my ability to communicate with others,but I fed up with some students
in union because I don’t like their character; I took part in many activities
in union,which enhanced my practice skills and accumulated a lot of social
experience,but it occasionally made me embarrassed in activities; It took me a
lot of time in union,which influenced my study.But at the same time,I enriched
my college life and made full use of my spare time.All in all,I think it is
worthy to join in the union.
I missed my dormitory and my room-mates.The
reasons as follows:Firstly,I shared my happinesses and sorrows with my
room-mates.in dormitory we talked and sung loudly and we made on decision on
something by absorbing everyone’s advice; but we inevitably had little
contradictions sometimes.Secondly,I relaxed myself sufficiently.I shout big
sleep when I was tired of one day’ study to alleviated fatigue and I freely
vented myself.But thanks to personal habits are different,we didn’t reach on
agreement on something.Lastly,the most regrettable is that the condition of
my dormitory is poor.The room is small and there is not bathroom; but I feel
very warmly because it’s my another family.I missed my dormitory very much
especially my room-mates.
Generally speaking,my college life is
interesting and rewarding.I was not only learnt basic professional knowledge
but also made many friends and enhanced my practical skills.The library
provided me a good learning environment.The union gave me practice platform.The
dormitory made me become a happiness girl.I missed my past university very
much.Now,I am in a new university and I think I will spend a more meaningfullpostgraduate life in there .

if there is no computer in our life,maybe we are going to lose a lots fun.we can't chat with our friends on line,and we can never download musci or movies from the internet.during the vacation,i bet a lot of people will feel boring and they may go to the bars,go to the cinema,the traffic may get worse.
but if there is no computer in our life,maybe students will have time to protect there eyes and they may find something more meaningful than playing video games.or they can spend more time doing their homework.
anyway ,there is computer in our life now.so how we are going to use them depends on oursevels.

1.——《老人与海》
The Old Man and the Sea is one of Hemingway’s most enduring works and may very well become one of the true classics of this generation.It played a great part in his winning the Pulizer Prize in 1953 and the 1954 Novel Prize for Literature and confirmed his power and presence in the literary world.Hemingway is also one of my favorite writers.Besides The Old Man And the Sea,I have read some of his other works,such as The Sun Also Rises,A Farewell to Arms and The Snow of Kilimanijaro.But The Old Man and the Sea is the one that left the deepest impression on me.
This novel mainly wrote one old person alone in marine fishes.He fished one big fish,tied up the fish head and the upper part of the body side the boat above.But he met the shark fish,the old person causes all one's skill and the shark fish fight,the shark fish the fish flesh which could eat all eats finished also has about 800 pounds.
This book promulgates the truth,not showed the person how regardless of,most feared is does not have the confidence.The confidence is just like is the automobile motor,is power which the person goes forward.
2.——《简爱》
The protagonist,Jane Eyre,as the author depicted,is very plain.But almost every reader,including me,must prefer Jane to any other young ladies in this novel.I think Jane possesses a kind heart,an indomitable spirit,a sharp wit and great courage.She loves Mr.Rochester even more when loses his hand and sight.
She never gives up her own independence and never easily follows the instructions or advices from people around her.Instead,Jane Eyre choose insist on her own beliefs and standards.
At first,Jane Eyre met her best friend,Helen Burns,in the Lowwood School.Though they two really intimate to each other,Jane cannot totally agree with Helen’s ideas about life and people.As Jane grows up,she choose to leave the school and work as a teacher,regardless of the critiques from others.
After the secret reveals that the insane woman in the old castle attic the insane woman is Mr.Rochester's wife,Jane Eyre is not willing to lose her dignity,condescends to her own desire.Actually,she leaves resolutely and silently.
Because of those kinds of brave and independent choices,Jane Eyre becomes one of the greatest women in my mind definitely.

You are what you eat." Nutrition experts often use this saying to promote better eating habits,what we put in our mouths does become a part of us.But we can look at this statement another way.What we eat reflects who we are -- as people and as a culture.Do you want to understand another culture?Then you ought to find out about its food.Learning about American food can give us a real taste of American culture.

《Chinese Cuisine Food Culture》
As a country that pays great attention to courtesy,our cuisine culture is deep rooted in China''s history.As a visitor or guest in either a Chinese home or restaurant you will find that table manners are essential and the distinctive courtesies displayed will invariably add to the enjoyment of your meals and keep you in high spirits!
Respect First
It is really an admirable custom to respect others at the table,including the aged,teachers and guests while taking good care of children.
Chinese people stress filial piety all the time.The practice of presenting the best or fine food first to the senior members of the family has been observed for countless generations.In ancient times the common people led a needy life but they still tried their best to support the elder mother or father who took it for granted.
Although the hosts in China are all friendly and hospitable,you should also show them respect.Before starting to eat dinner,the host may offer some words of greeting.Guests should not start to eat until the host says,''Please enjoy yourself'' or something like that,otherwise it suggests disrespect and causes displeasure.

Several decades ago,it should be a marvelous wonder to purchase our favorite gifts only by clicking the mouse and then just waiting for the door knock by a smiling expressive delivery courier with the exact package you ordered.While,today,it is no long a rare case.Combined with the fast food,the digital communication ,online shopping has been a common part of our life.Admittedly,on line shopping offers magical convenience.For example,it saves time and offers numerous choices since floods of information can be supplied on Internet.While,every coin has tow sides and online shopping is no different.Have you still remembered the annoying time when you found the commodities you buy on Internet was not the slightest as what you had expected and long time had to be taken for its replace and even compensation.Actually,just with the seemingly beautiful pictures of the products on Internet,it is hard for us to make rational choices.After all,seeing is believing.Then,what should we do?The foremost is to enforce establish some relevant laws and regulations,with strong supervision over some shopping websites being reinforced as well.Then,the consumers also should be equipped with more alert in case of being trapped once again.Remember,any fast –and- easy things asks for big prices to be paid.

A beautiful world
Hello:
everyone!Now I want to talk about a beatiful world!
When I was young,I always dreamed that I lived in a beautiful country. There were many flowers and trees around our city.We counld hear the birds singing and see the children dancing. The streets were clear and the the air was very fresh! How nice it was!But that only was a dream of mine!How I wish that it would be come true! So I think we should do something to protect our environment. Everyone should make a contribution to protect the environment.
Taking care of our environment is very important.Wherever you live,you can do something around your neighbourhood.
Have you ever thrown any litter onto the ground?Have you ever drawn pictures on public walls?Have you ever spat in a public place?Have you ever cut down trees?If your answers are "No",it means that you have already helped protect our environment.
It is our duty to keep our envionment clean and tidy. You might ask yourself,"Have I ever picked up some rubbish and thrown it into a dustbin?Have I ever collected waste paper or bottles for recycling?Have I ever planted any trees or flowers in or near my neighbourhood?"If your answers are"Yes",it means that you have already done something useful to improve the environment.
Now I want to say :Let`s do our best to make our world more beautiful!

1.The greatest invention in my eyes would be the invention of computers.Everywhere you look,a computer is in action.From everyday entertainment to national defence systems,nothing is possible without the aid of a computer.The reason for is that it can process much faster,more accurate and efficient than a human brain.Word processing,accounting packages,instant mailling,booking system...and the list goes on.The invention of computers has certainly made our lives much easier.
2.The bicycle was a great invention,It's was a popular means of transportation throughout the world.A bicycle took us to school or to work.A bicycle enables people to have enough time to do things.
In a modern society today,we have many new innovations in transportation,such as motor cars,motorcycles,aeroplanes,and mass rapid transportion or subway trains,etc.With these,we can travel for a long distance,far and near and as a result bicycle has far becoming extinct in a big city!
However,bicycle has its role still in small city or village.
Though the bicycle is considered 'old' We mist not forget the bicycle for it has served us for many decades.

He is finding a house to live in.
They set out early so as to catch the first train.
This puzzle is too difficult to work out.
My wish is to become a doctor.

愚公移山
Old Man Yu Moves the Mountains
Once upon a time,there were two mountains that stood right beside each other.The first was name,揟ai-Ying?and the second was named,揧ellow House.Both were over ten-thousand feet high,and together,they were four-hundred miles wide.
Facing the mountains lived Old Man Yu,who was over eighty-years-old and also known throughout the county for his foolishness.Every morning,as Old Man Yu walked to the village,his wife would shake her head as she saw him make yet another detour around the two mountains.As the years went by,he found it a great inconvenience to make these daily detours.So one day,Old Man Yu finally decided that the twin mountains would have to be moved.
He then called a family meeting and told his wife,sons,daughters,and their families of his intentions.揑 will move these two mountains,Old Man Yu cried,揳nd you will all help me do it!Old Man Yu抯 sons and grandsons thought it was a terrific idea.They cheered and gave him their undying support.Old Man Yu抯 wife sneered,揧ou are a foolish old man indeed!Just how would you go about moving two big mountains like Tai-Ying and Yellow-House?she continued,搉ever mind two mountains,I do not think you can even move two piles of cow-dung!And even if you could move the mountains,just where would you dispose of the dirt and rocks from the mountains?Huh?!she cried.
The old man thought for a moment,and without backing down answered her,揑 will throw out the dirt and rocks into a faraway place.I will throw them into the sea!Once again,Old Man Yu抯 sons and grandsons thought that it was a terrific idea to throw the dirt into the sea.They cheered a second time and pledged to him their dying support.Even the neighbouring widow抯 son named,Little Turnip Boy,gave the old man his support although he was only eight-years-old.
Off went Old Man Yu,his three sons,his many,countless grandsons,and Little Turnip Boy to work on removing Tai-Ying and Yellow House.It was such grueling work that in a year抯 time,Little Turnip Boy was only able to make one trip to the sea to dispose of the dirt and rocks.Nonetheless,no one lost their enthusiasm,as they all held steadfast to Old Man Yu抯 dream of having the two mountains removed.
Now on one of their trips to the sea,they met a man who lived along the Yellow River,who was known throughout the county for his cleverness and his arrogance.The clever man,who lived by the Yellow River mocked Old Man Yu saying,揧ou foolish old man!I have seen you,your three sons,your many,countless grandsons,and even Little Turnip Boy making trips to the sea to dispose of the dirt and rocks from the mountains.Do you think that you can actually remove two whole mountains?And look at you!You must be over ninety-years-old and closer to the grave as each day passes.How do you expect to move two mountains in your lifetime?
Old Man Yu looked upon the Yellow River Man with pity.揧ou are known throughout the entire country as a clever man.Yet,you are a man lacking in vision.Regarding this matter,even Little Turnip Boy has more wisdom than you.Old Man Yu continued,揧ou are correct in saying that I am an old man who is closer to the grave as each day passes.But I have three sons,and many,countless grandsons.In time,my grandsons will bear their own children,who,in turn,will bear even more children.So in time,my dream of removing these two mountains will become a reality.As each day passes,my dream can only increase,as these two mountains can only decrease.

这是我今天一起床第一个回答的问题.不知道你们会不会唱那首歌”If you’re happy and you know it”,如果不会就照读好了.唱歌的话效果会好些.

making friends on the internet can have both positive and negative effects.
on the good sight,we can learn to communicate with all kinds of people from all over the world,learn about their different cultures,and have a lot of fun.
however,it can also have some draw backs.sometimes,or to say,most of the times,we don't even know who we are talking with.so there might be some strangers who are not nice to you.if they arrange a meeting with you and try to harm you in any ways,you have to take care of yourself.there're many reported cases on the website about how people were hurt during those visits.
volunteer work is very important nowadays.schools often require students to do some volunteer work to broaden their minds,especially in high schools and universities.most of the students sweeps and cleans the floor or some companies for free.other go to restaurants and wash the dishes for them.but some of the students can go to labs to learn experiments.those were the really great volunteer works.it can allow you to learn a lot of useful knowledge,so i love those kinds of works very much.

1．从个位起向左每隔两位为一节,若带有小数从小数点起向右每隔两位一节,用“,”号将各节分开；
2．求不大于左边第一节数的完全平方数,为“商”；
3．从左边第一节数里减去求得的商,在它们的差的右边写上第二节数作为第一个余数；
4．把商乘以20,试除第一个余数,所得的最大整数作试商(如果这个最大整数大于或等于10,就用9或8作试商)；
5．用商乘以20加上试商再乘以试商.如果所得的积小于或等于余数,就把这个试商写在商后面,作为新商；如果所得的积大于余数,就把试商逐次减小再试,直到积小于或等于余数为止；
6．用同样的方法,继续求.
这种办法ms更适用于人+计算器,单用计算机做很繁琐.
后来请教Fish大牛,发现有更好的办法——逼近法：
要求sqrt(m),则设x^2-m=f(x),根据牛顿逼近法求f(x)=0的根.
例子：
1.4 1 4
----------
√2.00 00 00
1
----
24|1 00
| 96
-------
281| 4 00
| 2 81
--------
2824|1 19 00
|1 12 96
----------
.
其中24=1*20+4,281=14*20+1,2824=141*20+4
是以小数点为分界.每两位数为一记数点

1) 66x+17y=3967
25x+y=1200
答案：x=48 y=47

第一题中：若传送带回来之前能达到传送带速度,则共速.若回来没有共速,则就是原来的速度.向左运动时,摩擦力向右是阻力.返回时,如果一直都有滑到摩擦力（即速度小于传送带时）这样,两个运动是对称的.可以画V~T图.那么要让它回来速度小于传送带速度,则就去的速度要小于皮带的速度.所以当皮带速度大于物体速度时,回来的就等于其原来速度
当皮带速度小于物体速度时,回来的就等于皮带速度

Nowadays with the ever rapid development and increasing popularity of the information technology , shopping on the internet has been a fashion especially among the youngsters.
Online shopping has made our daily life more convenient and comfortable. For example , shopping on the internet can save students a great deal of time on the way between home and store, so they would be able to concentrate more time and energy on their academic work. The internet has shorten the distance between manufacturers and consumers and thus we can even buy goods in other countries .On the other hand , lack of the face to face deal makes online shopping less reliable and trustworthy. What’ s more the delivery will increase the risk of items’ damage.
In my opinion, shopping on the internet is a irreversible trend. More and more people will be accustomed to it. It will be much more popular in the near future. And at the same time we should take some measures to make it perfect.

1.用电过大时出现烧保险丝或跳闸现象.
2.有的插座是两只脚,有的是三只脚,那是多了一只单独接地的脚.
3.瓦数大的灯泡相同时间比瓦数小的灯泡要烫,那是因为瓦数大的功率大,发热也大.
4.电池供应的是直流电,插座供应的是交流电,一般电器是二相电,一般功率较大的机器用的是三相电.
5.在用电高峰期,灯泡有时会闪动,那是因为电线上的电压不稳,此时电压经常不到220V,中国用电是220V,而日本用电是110V.
