¡¾´ð°¸¡¿Mr. Principal,

I am Li Yue, a student from Class 5, Senior I.I am writing to draw your attention to some improper behavior among us students. Some students often litter and scribble at random, making our school dirty and unpleasant. It really has a bad effect on the image of our school. I always feel ashamed whenever I see these.

It is absolutely wrong for a student to litter and scribble about. Here, I advise that more dustbins should be placed around, which will be convenient for us to throw garbage into them. Additionally, we need make rules against such bad behavior so that students can develop good habits.

With the joint efforts of us, I am sure our school will become a more enjoyable place.

Thank you for your consideration.

Yours faithfully,

Li Yue

How to Improve Eyesight Naturally

Eyes are important for everybody. You must take care and try everything in your hand to keep them in good condition. Here are some of the tips to improve your eyesight naturally.

¡¾1¡¿ Strain is known to be a factor in many health conditions and eyestrain£¨ÑÛÆ£ÀÍ£© is no exception. Try meditation, yoga or other methods of stress relief to improve your vision and overall health.

Sit upright in a comfortable chair. ¡¾2¡¿ Cup your hands so that there is no pressure on your eyes. Let your fingers rest across your forehead. There should be no light entering your eyes. Palming£¨ÊÖÕÆ°´Ä¦£©should be done for a period of 5 to 10 minutes to start. Palming should be relaxing. It may help to do palming in a darkened room.

¡¾3¡¿ It will unpleasantly affect your eyesight, which affects the eyes by producing a larger amount of insulin (ÒȵºËØ) in the blood. Therefore you shouldn¡¯t be having much fruit juice or something that contains a lot of sugar.

The only exercise most eyes get is that daily rubbing we give them when we're tired or suffering from eyestrain. But eye exercises are actually good for your eyes and can improve your vision. ¡¾4¡¿ Blink as fast as you can for a few seconds then close your eyes tightly, open and repeat. Do this exercise 3 to 4 times daily.

You probably hear that statement all the time but eating the right foods are necessary to good health. ¡¾5¡¿ Foods that are high in fiber, vitamin C, D and beta carotene as well as other vitamins and minerals can help improve your vision. Here are a few foods that can be beneficial to good vision: carrots, eggs, blueberries, spinach, kale, grapes, and fresh garlic.

A. Reduce eyestrain.

B. Keep your eyes moist£¨ÊªµÄ£©.

C. Sugar is your eye¡¯s worst enemy.

D. Give your eyes a workout with the following exercise.

E. You may not be aware that your diet affects your vision but it does.

F. Close eyes and cover them with the palms of your hands.

G. Be sure to get plenty of sleep so your eyes don¡¯t strain to stay open during the day.

Five Things Ambitious People Never Say

¡ô¡°I can¡¯t do this¡ªit¡¯s too hard.¡±

Ambitious people never limit themselves or undervalue hard work with these words. ¡¾1¡¿ .

¡ô¡°I¡¯m not good enough.¡±

Ambitious people never say they are not good enough. Saying you are not good enough holds you back and makes you easy to quit when things get a little rough. And quitting when things get a little rough is never a good thing. The most successful people in the world are not quitters. ¡¾2¡¿ Be confident and believe in yourself, or no one else will.

¡ô¡°I won¡¯t make it through the obstacles(ÕÏ°­).¡±

Challenges and obstacles are tests of your resolve(¾öÐÄ) and desire to succeed. ¡¾3¡¿ They say they will make it because they know better things lie ahead-the sun always shines after the storm.

¡ô ¡¾4¡¿

The only time people won¡¯t take you seriously is if you don¡¯t take yourself seriously. Insisting that people won¡¯t take you seriously is an excuse not to do what you know you should do. Ambitious people never say these words. Start respecting yourself and honoring what you do and people will respect and take you seriously.

¡ô¡°I¡¯m going to fail for sure.¡±

¡¾5¡¿ It can teach you valuable lessons and redirect you to the right path. Ambitious people don¡¯t say they are going to fail and let that stop them from trying. They challenge the fear of failure by taking calculated risks(¸Êð·çÏÕ) because they know the only time you are truly defeated is when you don¡¯t try at all.

A. Ambitious people never say they won't make it through the hard times.

B. They are hard workers who believe in themselves and their abilities.

C. Failure is not entirely bad.

D. They tell themselves they can do it.

E. ¡°People won¡¯t take me seriously.¡±

F. ¡°People think me impossible.¡±

G. Ambitious people say they can do everything well.

¡¾ÌâÄ¿¡¿America is a mobile society. Friendships between Americans can be close and real, yet disappear soon if situations change. Neither side feels hurt by this. Both may exchange Christmas greetings for a year or two, perhaps a few letters for a while ¡ª then no more. If the same two people meet again by chance, even years later, they pick up the friendship. This can be quite difficult for us Chinese to understand, because friendships between us flower more slowly but then may become lifelong feelings, extending (ÑÓÉì) sometimes deeply into both families.

Americans are ready to receive us foreigners at their homes, share their holidays, and their home life. They will enjoy welcoming us and be pleased if we accept their hospitality (ºÃ¿Í) easily.

Another difficult point for us Chinese to understand Americans is that although they include us warmly in their personal everyday lives, they don¡¯t show their politeness to us if it requires a great deal of time. This is usually the opposite of the practice in our country where we may begenerous with our time. Sometimes, we, as hosts, will appear at airports even in the middle of the night to meet a friend. We may take days off to act as guides to our foreign friends. The Americans, however, express their welcome usually at homes, but truly can not manage the time to do a great deal with a visitor outside their daily routine. They will probably expect us to get ourselves from the airport to our own hotel by bus. And they expect that we will phone them from there. Once we arrive at their homes, the welcome will be full, warm and real. We will find ourselves treated hospitably.Z*X*X*K]

For the Americans, it is often considered more friendly to invite a friend to their homes than to go to restaurants, except for purely business matters. So accept their hospitality at home!

¡¾1¡¿The writer of this passage must be ______.

A. an American B. a Chines

C. a professor D. a student

¡¾2¡¿Which of the following statements is TRUE according to the passage?

A. Friendships between Americans usually extend deeply into their families.

B. Friendships between Americans usually last for all their lives.

C. Americans always show their warmth even if they are very busy.

D. Americans will continue their friendships again even after a long break.

¡¾3¡¿The underlined words ¡°generous with our time¡± in Paragraph 3 probably mean ______.

A. strict with time B. serious with time

C. careful with time D. willing to spend time

¡¾4¡¿A suitable title for this passage would probably be ¡°______¡±.

A. Friendships between Chinese

B. Friendships between Americans

C. Americans¡¯ hospitality

D. Americans¡¯ and Chinese¡¯s views of friendships

Every year there are changes in climate in different parts of the world.Some of these changes are due to natural causes.However,some climate changes are caused by air pollution and these changes may increase.

If the pollution affects the level of carbon dioxide in the atmosphere,the results are likely to be serious.There is only a small part of carbon dioxide in the atmosphere.But it has an important function in keeping the balance between radiation from the sun entering the atmosphere and radiation leaving the Earth.Some of the radiation is absorbed by the Earth and some is radiated back into the atmosphere.The carbon dioxide in the atmosphere prevents some of the radiation from leaving the atmosphere.Thus the heat remains in the atmosphere and carbon dioxide helps to prevent the temperature of the Earth from falling.

If the proportion(±ÈÀý)of carbon dioxide in the atmosphere is increased as a result of air pollution,the temperature of the atmosphere may rise.This might cause the ice in the North and South to melt.If this happened,the sea level could rise and parts of the Earth would be flooded.This is not quite likely but the possibility exists.

There is also a fairly strong possibility that the dust level in the atmosphere will rise as a result of industrial pollution.This dust pollution will reflect sunlight back onto space.If this happens,less sunlight will reach the Earth and the temperature will fall.

Another danger comes from the destruction(ÆÆ»µ)of the Earth¡¯s vegetation(Ö²Îï)such as the forest of Brazil,which is being cleared away for farmland and cities.Trees use carbon dioxide and their destruction may upset the balance of carbon dioxide in the atmosphere.

¡¾1¡¿The main purpose of the passage is to tell us that .

A.the climate of the earth is always changing

B.air pollution has greatly affected the climate of the world

C.carbon dioxide has something to do with climate changes

D.the climate of the world is subjected to(ʹÊܵ½)dangers from air pollution

¡¾2¡¿From this passage we learn that carbon dioxide .

A.helps to prevent the temperature of the Earth from rising

B.keeps much of the sun¡¯s radiation from entering the atmosphere

C.plays an important part in keeping the balance of the temperature of the Earth

D.is one of natural causes of climate changes

¡¾3¡¿Judging from this passage,if the level of carbon dioxide in the atmosphere went down,the temperature of the Earth would .

A.become higher B.either rise or fall

C.become lower D.neither rise nor fall

¡¾4¡¿Which of the following is not the possible serious outcome if air pollution is related to climate changes?

A.Parts of the Earth would be flooded one day.

B.More sunlight would reach the Earth.

C.The temperature of the Earth might rise.

D.The Earth¡¯s vegetation might be destroyed.
