Keeping pace with teachers is a fine way to study English. Teachers are experienced and their plans are systematic. But remember to work in a way that suits you. It's important to learn from past mistakes as well. Keep a notebook to make a record of the mistakes you have made―it'll help you avoid making the same ones later.
The time of life may be hard,but you're not alone. You may be busy studying,but you can show your care by calling your friends or sending short mes?sages. Don't let your friendships die.
It's as important to live well as it is to study well. Going to bed no later than 11 ： 30 pm is vital. It puts you in the right mood for the next day. You needn't follow a special diet,but make sure you are eating nu?tritious meals each day.
The person who plays well studies well. Having a lot of schoolwork doesn't mean having to give up other activities. Playing basketball or having a talk with your classmates can relax yourself. Timeout is not a waste of time but helps you study more efficiently.
Besides taking the big exam,you have other choices for college. I took the independent enrollment exam held by Peking University and some other students even were preparing to study abroad.

A In the atmosphere,carbon dioxide allows the sun's rays to enter but prevents the heat from escaping. According to a weather expert's prediction,the atmosphere will be warmer in the year 2050 than it is today,if man continues to burn fuels at the present rate. If this war?ming up took place,the ice caps in the poles would begin to melt,thus raising sea level several metres and severely flooding coastal cities. Also,the increase in at?mospheric temperature would lead to great changes in the climate of the northern hemisphere.
In the past,concern about manmade warming of the earth has concentrated on the Arctic because the Antarctic is much colder and has a much thicker ice sheet. But the weather experts are now paying more attention to West Antarctica,which may be affected by only a few degrees of warming,in other words,by warming on the scale that will possibly take place in the next fifty years from the burning of fuels. Satellite pictures show that large areas of Antarctic ice are already disappea?ring. The evidence suggests that warming has taken place. This fits the theory that carbon dioxide warms the earth.
However,most of the fuel is burnt in the northern part of the earth,where temperatures seem to be falling. Scientists conclude,therefore,that up to now natural influences on the weather have exceeded those caused by man. The question is：Which natural cause has most effect on the weather?
One possibility is the behaviour of the sun. Astronomers at one research sta?tion have studied the hot spots and cold spots,that is,the relatively less hot spots,on the sun. This seems to have a greater effect on the distribution of the earth's at?mospheric pressure,and consequently on wind circulation (循環) .The sun is also variable (可變的) over a long term. Its heat output (輸出) goes up and down in cycles. The latest trend being downward is on the way. But that is only an imagination.
1. The carbon dioxide in the atmosphere would .
A. prevent the sun's rays from reaching the earth's surface
B. mean warming up in the Arctic
C. account for great changes in the climate
D. raise the temperature of the earth's surface
2. The article is written to explain ,
A. the greenhouse effect
B. the solar effects on the earth
C. the solar weather
D. the causes affecting weather
3. Although the fuel is greater in the northern part,temperatures there seem to be falling. This is .
A. mainly because the carbon dioxide is rising
B. possibly because the ice caps in the poles are melting
C. due to the effect of the earth's climate
D. partly due to the activity of the sun
4. What does the underlined word "exceeded" in Paragraph 3 mean?
A. To be the same as. B. To be slower than.
C. To be better than. D. To be bigger than.
