The news that Mr Cai had passed away was known, and I fell into great

sorrow. The sound of the rain knocking on the window was so mournful that it

deepened my distress.

My memory brought me back to the class when I saw him for the last

time.

That evening it was raining, too. We started our lesson as usual at a

quarter past six. I sat in the first row, and I saw Mr Cai press his stomach

with a hand from time to time, but I didn’t know the reason then. The two hours

passed quickly. When the lesson came to an end,Mr Cai told us that he had

possibly developed a stomach cancer, and would go to Beijing to see a doctor. If

there was nothing serious, he would continue to teach us after he came back. He

was very calm and his voice was steady. He still gave us some homework. He said

that he would mark the papers as soon as he came back.

Then I started to wait for his return. I had not thought that I would not

see him any more. The cancer had taken his life, even though he was still

young.

Mr Cai’s words are still ringing in my ears,“I hope you will be one of the

best students.” I think I should work hard at English and live up to his

expectation .

I have lost a good teacher. Tears will dry up in time, but the memory will

stay for ever.

Bike-sharing has been advocated by the government in recent years. It

offers help to the people who is in a hurry to reach the destination soon, the

more important is to let more people back to the simple traffic style and reduce

private cars, so as to protect our environment. But some people make use of this

policy to take advantages of others. News report that some middle age men and

women force people to give charge after finishing using bike-sharing, because

they look after the bikes. It is known to all that bike-sharing is free, which

is the convenience government offers to the public. It is ridiculous to charge.

When the news exposed, the public know the truth and the ones who take charge

are criticized. Under the government’s supervision, now bike-sharing is more

popular.

One way to get around in big cities like Beijing and Shanghai is to take a

taxi, but it’s too expensive. Many people like to go out by subway or light

rail. They are very fast and convenient. Now they are becoming more and more

popular. Buses are cheap, but they are very slow in rush hours.

If you want to see a city well, you can go out by bike. However, most

people prefer to get around in a downtown area on foot, because it’s good for

health.

Today, Chinas economy has made the great achievement. More and more

foreign people come to China to seek for cooperation. It is true that peoples

life standard has been improved a lot during the last decades, but the

environment has been polluted badly. When I was very small, I could see the

green trees and clean water around my hometown, but now, the river becomes

smaller and the rubbish can be seen everywhere. I feel so sad about it. We have

sacrificed so much to chase the profit. If we cant save the environment, we

wont live the comfortable life. For us, we should not throw away the rubbish

and plant more trees. The little things we do will make a great difference.

The summer holiday is coming. Our class have had a discussion about what to do during the holiday. Some are in favor of staying at home. They think its both convenient and comfortable. Whats more, they can save money for other purposes. But they will lose the chance of getting to know the outside world.

However, others prefer to go out for traveling since it can increase their knowledge and broaden their horizons. But they will spend more money and meet some difficulties while traveling.

In my opinion, it would be much better to stay at home, for I can do what I like, such as reading books, watching TV, and helping my parents with the housework.

随着现代科学技术的迅速发展，我们已经走出了以前茹毛饮血的时代，来到了科技发达的年代。科技的发展给我们的生活带来了极大的方便。

以前发愁晚上没有光明，而这天的夜晚家家户户都灯火通明；以前想尝尝海中的美味，都是很奢侈的，而此刻鱼肉虾肉都是家常便饭；以往总觉得家信难传，而这天涯若比邻……是的，科学带给我们的一系列的好处是不容忽视的！

唐朝杨贵妃想吃新鲜的荔枝，但是新鲜荔枝是在南方才能吃到的，于是，皇帝派人骑着快马千里迢迢从远在千里以外的地方运输过来，为了保证新鲜，累死了多少匹快马啊！但是如今，想吃到新鲜荔枝在市场随处可见，是普通百姓桌上的家常便饭。可见，科技的发展给我们带来多大的方便啊！

在古代，背井离乡的游子由于长期在外生活、工作，十分想念家乡的亲人，写一封家信，寄出以后，家人却迟迟没有回信……为什么呢？因为那封信可能没有寄到家人手中就丢在半路上了；还有可能是寄出十分久了，家人才收到，再回一个信，在外的游子可能要一两个月才能收到家人的回信，因此，给远方的亲人说一句话都很困难。

此刻好了，能够给在远方的家人发信息，速度很快，不到一秒钟对方就能够明白你想说什么，不仅仅能够对话，还能够视频聊天，这样，就随时能够与在远方的亲人聊天了，也能够看见在远方亲人的模样了，要是在以前，能够与远方的亲人见一面，那是多么幸福快乐的一件事啊！人民没法解决的东西，科学技术必须能帮你解决，比如，学习遇到困难，只要打开电脑，打打字，正确的说法就会显示在电脑的显示屏幕上。只要有了科学，再大的困难都不用愁了。

但是，科学技术在发展的同时，却忽略了环境的问题。大规模地把废水排放在河里，使人们吃不到放心的海鲜，大规模地浪费宝贵资源，却从来不想后果是多么地严重。在科技发展的同时，也要保护好环境。

科技，是一把双刃剑，它是我们人类前进的动力，它给我们带来方便，带来发展，同时也带来了许多负面的影响。我们要充分利用科技带来的好处，也不能忽略我们赖以生存的环境哦。

An essential quality for young people is diligence.Nowdays,the issue on the

most important personal quality of young people is highly debatable,and ideas

vary from peerson to person. Some would claim that confidence is the most

essential. But for my part,the most essential quality for young people is

diligence that helps us a lot.

Diligence enables us to academic results. As we all know,academic results

requires lots of researches. An ancient calligraphy,named Wang Xizhi,devoted

lots of his time practicing writing. As is known to us all,he dried his pool

with his writing brush day after day. Though diligence,he became the greatest

calligraphy,finally.

Deligence helps us to achieve better scores in school. Last semester,one of

my fellow students failed to pass the Listening cours. In fact, questions set in

that paper were not very difficultt. If she had spent a little more time

listening rather than watching TV at her dorm,she could have passed the exam. On

the other hand,one of my roomates worked hard every day and got a high

score.

Diligence provides us more chancs to be succeed. As the saying goes “The

early bird catch the worm”. A diligent man may get up early and have more time

to improve himself. And that is the key to be succeed. If

we spend some time observing people around us,we can easily find some

people,just like Li Jiachen,are diligence and successful.

All in all,as a young people,once we have cultivated the essential quality

of diligence,we can achieve academic achievements,get a high score and have more

chances to be succeed. Once we have this essential quality:diligence,it do helps

us a lot in many ways.

It’s beyond reproach that we will come across all kinds of difficulties and

challenges in our life time .Some will be subjected to frequent sadness .Some

will lose their way to move on .Thus,only when we equip ourselves with hope and

courage can we finally succeed in the uncertain future.

Forrest Gump showed so great courage in the movie that he touched me a lot

. For one thing,no matter when and where Jenny got into trouble ,Forrest Gump

would bring her out of it without thinking how dangerous the situation would be

.Maybe we should all fell ashamed that we love ourselves more than we love love

,but Forrest showed great courage in love .For another,Forrest gump risked his

life to save Bubba in the war.It’s courage that helped Forrest gain a series of

honor after war .Forrest Gump is beautiful for his perseverance and touches

others with his courage.

A person can’t do without courage in terms of love and friendship ,let

alone life . A weak person may avoid the difficulties ,but a person with courage

will face up to it head-on. Therefore,let’equip ourselves with great

courage.

We can see such signs as “No Smoking” in some public places, which is a

kind of measure taken to ban smoking in public places. However, concerning about

this measures, different people hold divergent opinions. The smokers protest

against that it is a kind of action to deprive of their free right, while the

non-smokers are in favor of banning smoking in public places.

In my opinion, I am inclined to support the latter one—smoking should be

banned in public places. There are reasons accounting for my point. For one

thing, people will be harmed by the second-hand smoking if someone smokes in

public places, especially the infants and children. For another, banning smoking

in public places is also beneficial to the smokers. If they are banned to smoke

in public places, they will restrain themselves from smoking and smoke less. In

the meantime, it is a contribution to reduce the air pollution.

Therefore, I advocate that smoking in public places should be banned so

that we can breathe the fresh air and suffer less from the second-hand smoking.

Let’s work together to create and sustain out green and fresh environment.

Olympic Games is the biggest event for the players, because it holds every

four years. I remembered that my father watched the games at midnight many years

ago, and I did not understand why he was so crazy about it. Now I watched the

game with him and I started to appreciate the charm of sports. No matter what

the result is, standing in the biggest stage and competing with the greatest

rivals make the players feel proud. They chase to be higher, stronger and faster

and these are the spirit of Olympic Games. When the audience see the players

break the record and challenge human being’s limitation, how excited it is.

Recently, the news reported that one special kind of rhino from Africa just

passed away, which meant the disappearance of this lovely creature. What a great

pity. The tragedy is caused by the damaged environment, while human being must

be blamed for it, because we have done so many bad things to pollute the

environment and make the nature lose its balance. In order to make up our faults

and save our offspring, it is in need of protecting the environment. As the

ordinary people, we can do the small things, such as do not throw away the

rubbish and join some activities to bring the world green, like planting trees.

Every small act can make a difference. Some day, when we live with the

environment friendly, what we do is worth.

It is believed that the computer is bringing the world into a brand new

era. At the time the computer was invented, scientists, marveling at its

calculating speed, felt that they had created a miracle. Nowadays, the function

of the computer is no longer confined to calculation; it permeates people’s

daily lives and has become an inseparable part of human society.

People become so heavily dependent on computers that it is hard to imagine

the life without computers. Therefore, some people are worried that “The real

danger is not that the computer will think like man, but man will think like the

computer.”

Their concern does make sense. Indeed, some people spend such a long time

working on computers that they have few interactions with people in real life.

According to a research, too many hours in front of a computer may lead to a

poker face and interpersonal isolation. This fact should arouse our attention,

because unlike computers, human beings are social creatures that need emotional

connections with others.

Yet, it is also unnecessary for us to be overwhelmed by the negative

impacts of computers. After all, we humans are intelligent and will be able to

figure out better ways to make improvements.

One day, mother and i went to climb mount huang. when i began to climb, i

felt very easy. but when i climbed the haft way, i was very tired.and quite out

of breath. i asked mother, "can i climb to the top?" mother answered, "as long

as you have courage, you can conquer every mountain,

no matter how high it is! "so i went ahead. half an hour later, i climbed

to the top finally. what a wonderful day i had!

In spite of objections from public opinion， many students cant draw themselves away from video games. It seems that the more they are prohibited from playing the games， the more they are tempted to do so. Many students indulge themselves in playing these games.

Video games are harmful to both the inzidual and society in many ways. First， they endanger the young peoples health. Sitting in front of the computer for hours on end is bad for the players eyesight as well as his entire physique. Secondly， they distract the young people attention from their work and study. Absorbed in the games， the player often forgets to go to work or class. Sometimes even if they are at work or in class， they are still thinking of the games they played or are going to play after work or after class. As a result， they quickly fall behind others in their work and study. Thirdly， they lead young people to moral degradation. Some young people are especially interested in games that are filled with violence. If they play these games a long time， they may also settle disagreements through violence， which may give rise to higher crime rate.

Therefore， it is time we took effective measures to solve this problem. On the one hand， young people should be made fully aware of the danger of video games. On the other， illegal video game houses should be eliminated， and software producers should be encouraged to make more beneficial video games in the future.

Nowadays, electronic music is very popular around the world. First electronic music got popular from Lady Gaga, her creative dressing styles caught people’s attention and then people started to notice her music. They fell in love with her electronic music. Unlike rock and roll music, electronic music is more favorable by me. It makes me excited and I am totally lost in the wonderful music. Once my friends and I went to a music festival. There were so many people standing there and listening to the music. Especially when the DJ came out and everybody got excited. When the DJ played electronic music, my friends and I shook our bodies and joined the crowd to dance. It was such a wonderful experience for me. I will never forget the power of electronic music. It brings people together and share the same emotion.

电子音乐现在在世界各地都很受欢迎。电子音乐是从Lady Gaga开始流行的，她奇特的穿衣风格引起了人们的注意，然后大家开始注意到了她的音乐，并且爱上了她的电子音乐。它跟摇滚音乐不一样，我更加喜欢电子音乐，这可以让我兴奋。我完全迷失在美妙的音乐中。有一次我和我的朋友们去了一个音乐节。很多人站在那里听音乐。特别是当DJ出来时，每个人都很兴奋。DJ播放电子音乐时，我和我的朋友都扭动着身体，加入了人群中跳起舞来。这对我来说是那么奇妙的经历。我永远不会忘记电子音乐的力量，它使人与人走到一起，分享着相同的情感。

Everyone will have some unforgettable memories. These big and small

memories are like the shining stars in my memory, and one of them is the first

time I read science books.

It was the second day of the summer vacation for Daban. It was sunny and a

little sultry in the morning. My father said to me happily, "son, today my

father will take you to climb the mountain and enjoy the beautiful scenery on

the top of the mountain." I readily agreed. So we came to the famous Dayang

mountain in Dongzhu.

My father and I went to the foot of the mountain, looked up, and could not

see the top of Dayang mountain. My father said, "climb to the top of the

mountain and you can enjoy the most beautiful scenery in the world." I look

forward to my father.

At the beginning of climbing, I was full of energy and very relaxed. But

when I climbed to the middle of the mountain, my body became heavier and heavier

like lead. Dad saw me like this, so we rested for a while, and continued to

climb up. After a long time, I saw that I was exhausted when I was near the top

of the mountain. I begged dad to take me down the mountain. Dad encouraged me:

"hold on a little longer, and soon I will be at the top of the mountain Well,

the ancients said, "you will be at the top of the mountain and see all the small

mountains." dont you want to experience this feeling? " I gasped and said, "Dad,

I really cant climb. I cant move my legs anymore. I want to go back..." Dad

helplessly took me down the mountain.

At that time, I didnt stick to it. Unfortunately, I missed the beautiful

scenery at the top of the mountain. Ive learned that if I do anything, work hard

and stick to it to the end, there will be gains. Study is also, persist in the

end will achieve good results.
