Did you see snow in your hometown last winter? Did you feel it was warmer than before?

"There have been 21 warm winters in China since 1986," said scientists. They also said that in the past 100 years, as the global (全球的) temperatures went up by 0.74 °C , the temperature in North China has climbed 1.4 °C in only 50 years.

China needs to take quick action to cut carbon dioxide emission (排放)

because it's the main reason for global warming. The good news is that China has seen the importance of going green. China set the goal of cutting energy use by 20% and pollution emission by 10% in the 11th Five-Year Plan.

Can you slow down global warming? Sure! You and your family can take steps to cut the amount of carbon dioxide that is sent out into the air.

科目：初中英語(yǔ) 來(lái)源：2011-2012學(xué)年江蘇省常州市武進(jìn)區(qū)九年級(jí)5月調(diào)研測(cè)試英語(yǔ)試卷（解析版） 題型：閱讀理解

A study finds that not enough morning light causes teenagers not to get enough sleep at night. “As teenagers spend more time indoors, they miss necessary morning light. Day light is needed to keep the balance of the body’s 24-hour biological system (生物系統(tǒng)), which regulates (調(diào)節(jié)) body temperature and sleep styles,” reports Dr. Mariana Figueiro. “These teenagers who receive little morning light are going to bed later, getting less sleep and doing badly in tests. They are more likely to fail in their exams.”

In the study, Dr. Figueiro asked 11 students in Grade 8 to wear special glasses to prevent blue morning light from reaching their eyes. At the end of the 5-day study she found that they fell asleep 30 minutes later than usual.

Throughout her research, Dr. Figueiro has been very worried about teenagers going to bed too late. The problem is that today’s schools require teenagers to be in school very early in the morning. These students are likely to miss the morning light because they often go to school before the sun is up or as it’s just rising.

Furthermore (此外), the schools are not likely to provide enough electric light to keep the balance of this biological system. Our biological system is much more sensitive (敏感的) to blue light. Therefore, having lots of light in the classroom does not make sure that there is enough light to keep our biological system balanced.

1.Which of the following is the result of the study?

    A. Blue light in the morning harms the biological system.

    B. Not enough morning light keeps teenagers sleep less.

    C. Not getting more light in the morning make teenagers happy.

    D. Not enough sleep makes teenagers fail in tests.

2.We know from the passage that morning light __________.

    A. has the same effects as afternoon light                 

B. may change studying habits of teenagers

    C. is important to children’s biological system           

D. has no effect on students’ tests

3.What’s the problem of the students according to the study?

    A. There are not enough electric lights in the classroom.

    B. Being in school early affects their study habits.

    C. They have to go to bed very early to have enough sleep.

    D. They go to school too early to get enough morning light.
