In the atmosphere , carbon dioxide acts rather like a one-way mirror or the glass in the roof of a greenhouse which allows the sun’s rays to enter but prevents the heat from escaping.

   According to a weather expert’s prediction, the atmosphere will be 3 ℃ warmer in the year 2050 than it is today, if man continues to burn fuels at the present rate. If this warming up took place, the ice caps in the poles would begin to melt, thus raising sea level several meters and severely flooding coastal cities. Also, the increase in atmospheric temperature would lead to great changes in the climate of the northern hemisphere(半球), possibly resulting in an alteration of the earth’s chief food growing zones.

   In the past, concern about a man-made 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 Antarctic, which may be affected by only a few degrees of warming, in other words, by a 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 disappearing. The evidence available suggests that a warming has taken place. This fits the theory that carbon dioxide warms the earth

   However, most of the fuel is burnt in the northern hemisphere, where temperatures seem to be falling. Scientists conclude, therefore, that up to now natural influences on the weather have gone beyond those caused by man. The question is: Which natural cause has most effect on the weather?

   One possibility is the variable behavior of the sun. Astronomers at one research station have studied the hot sports and ‘cold” spots( that is, the relatively less hot spots) on the sun. As the sun rotates(使旋转), every 27.5 days, it presents hotter or colder faces to the earth, and different aspects to different parts of the earth. This seems to have a considerable effect on the distribution of the earth’s atmospheric pressure, and consequently on wind circulation. The sun is also changeable over a long term: its heat output goes up and down in cycles, the latest trend being downward.

   Scientists are now finding shared relations between models of solar weather interactions and the actual climate over many thousands of years, including the last Ice Age. The problem is that the models are predicting that the world should be entering a new Ice Age and it is hot. One way of solving this theoretical difficulty is to assume a delay of thousands of years while the solar effects overcome the inertia(惯性) of the earth’s climate. If this is right, the warming effect of carbon dioxide might thus be serving as a useful opposed balance to the sun’s fading heat.

It can be concluded that concentration of carbon dioxide in the atmosphere would ____.

A. mean a warming-up in the Arctic.              

B. raise the temperature of the earth’s surface.

C. prevent the sun’s rays from reaching the earth’ s surface.

D. explain the cause of great changes in the climate in the northern hemisphere.

The article was written to explain____.

A. the greenhouse effect.          B. the solar effects on the earth.

C. the causes affecting weather.     D. the models of solar weather of solar weather interactions.

Although the fuel consumption is greater in the northern hemisphere, temperature there seems to be falling. This is ____.

A. mainly because the levels of carbon dioxide are rising

B. partly due to changes in the output of solar energy

C. possibly because the ice caps in the poles are melting

D. only due to the effect of the inertia of the earth’s climate

On the basis of their models, scientists are of the opinion that     .

A. the climate of the world should be becoming cooler

B. the new Ice Age will be delayed by the greenhouse effect

C. the man-made warning effect helps to increase the solar effects

D. it will take thousands of years for the interia of the earth’s climate to take effect.

If the assumption about the delay of a new Ice Age is correct, ___.

A. ice would soon cover the northern hemisphere.

B. the greenhouse effect could work in favor of the earth.

C. the best way to overcome the cooling effect would be to burn more fuels.

D. the increased levels of carbon dioxide in the atmosphere could warm up the earth even more quickly.

Some say everyday miracles(奇迹) are predestined(注定的)—the right time for the appointed meeting. And it can happen anywhere.
In 2001, 11-year-old Kevin Stephan was a bat boy for his younger brother’s Little League team in Lancaster, New York. It was an early evening in late July. Kevin was standing on the grass away from the plate, where another youngster was warming up for the next game. Swinging his bat back and forth, giving it all the power an elementary school kid could give. The boy brought the bat back hard and hit Kevin in the chest. His heart stopped.
When Kevin fell to the ground, the mother of one of the players rushed out of the stands to his aid. Penny Brown hadn’t planned to be there that day, but at the last minute, her shift(换班)at the hospital had been changed to see her son’s performance. She was given the night off. Penny bent over the senseless boy, his face already starting to turn blue, and giving him CPR(心肺复苏术), breathing into his mouth and giving him chest compressions. And he revived in the end.
After his recovery, he became a volunteer junior firefighter, learning some of the emergency first-aid techniques that had saved his life. He studied hard in school and was saving money for college by working as a dishwasher in a local restaurant in his spare time.
Kevin, now 18, was working in the kitchen when he heard people screaming, customers in confusion, employees rushing toward a table. He hurried into the main room and saw a woman there, her face turning blue, her hands at her throat. She was choking.
Quickly Kevin stepped behind her, wrapped his arms around her and clasped his hands. Then, he used skills he’d first learned in Scouts. The food that was trapped in the woman’s throat was freed. The colour began to return to her face.
“The food was stuck in my throat. I couldn’t breathe,” she said. She thought she was dying. “I was very frightened.”
Who was the woman?
Penny Brown.

       Learning another language isn't easy, but most people can learn a second language well if they’re willing to put in the necessary time. Here are some practical suggestions for studying effectively, overcoming anxiety, and learning the grammar and skills necessary for success in foreign language classes.

Study every day

Language learning is cumulative: you cannot put it off until the weekend. Study one or two hours for every class hour if you want a good mark.

Distribute your study time in 15 to 30 minutes period throughout the day

Study a different task each time: vocabulary now, grammar next, etc. Get an overview during the first half hour: spend 10 minutes reviewing dialog, 10 minutes learning new vocabulary, 10 minutes learning new grammar... So you'll at least have looked at it all. About 80~of your study time should be spent on recitation or practice.

Attend and participate in every class—even if you aren't well prepared

Class time is your best opportunity to practice, learn the grammar and vocabulary outside of class in order to make full use of the class time. Spend a few minutes "warming up" before each class by speaking or reading the language.

Make yourself comfortable in the classroom

Get to know your classmates, so you'll feel you’re among friends. Visit your teacher during office hours to get aquainted(熟悉的)：explain your goals and fears about the course to your teacher.

Learn grammar if you don't already know it

Grammar is the skeleton(骨架) and the basic structure of a language, and you must learn it.

Practice for tests by doing what you'll have to do on the test

If the test will require you to write, then study by writing--including spelling and accents. If you're asked to listen, practice listening. Ask for practice questions and make up your own test questions. Try to invent changes on patterns and forms. Over learning is also required in tests preparation：study beyond the paints of recognition to mastery.

Develop a good attitude

Have a clear personal reason for taking the class. Set personal goals for what you want to learn. Leave perfectionism at the door; give yourself permission to make mistakes and learn from them.

16. What does the underlined word "cumulative" in Paragraph 2 probably mean?

    A. process of gaining knowledge or skill by doing and seeing things

    B. having to do with comparison

    C. having ability to do what is needed

    D. increasing in amount by one addition after another

17. A good learner is one who ________ according to the passage.

    A. never permits himself to make mistakes

    B. can learn something from the mistakes he makes

    C. follows the goals that other persons set for themselves

    D. can get to know his classmates and doesn't take his teachers' advice

18. What would be the best title for the passage?

   A. Tips on studying a foreign language. 

   B. Advice on how to learn grammar.

   C. Suggestions for studying vocabulary effectively.     

   D. How to make yourself comfortable in the classroom.
