題目列表(包括答案和解析)

寫作
        閱讀下面的短文，然后按照要求寫一篇150詞左右的英語短文。

     The U. N. Climate Change conference opened in Copenhagen, Denmark on Dec.7th with some
15,000 delegates and observers from nearly 200 countries attending what is called the last best chance
for an agreement to combat global warming.
     Most scientists believe the warming trend is mainly caused by human activity, especially the use of
fossil fuels (化石燃料) and the cutting down of forests. In Copenhagen, experts and officials alike are
putting the emphasis on what people and governments can do to cut the emission (排放) of greenhouse
gasses. Scientists say a 25 to 40 percent cut in carbondioxide emissions is needed to control global
warming.
     A youthful online group that calls itself the "LowCarbon Tribe"  is leading the way to an ecofriendly
lifestyle. Tribe members, who range in age from 20 to 40, say they are trying to reduce carbon dioxide
emissions in a relaxed and fashionable way. Helping save the planet is part of their daily routine, they
claim, citing the way they dress, what they eat and how they travel.
      【寫作內(nèi)容】  1．以約30個詞概括這段短文的內(nèi)容；
                                2．然后以約120個詞就“低碳生活”進行議論，
         內(nèi)容包括： (1)低碳生活所包含的出行方式，節(jié)能等方面，并具體舉例說明；
                               (2)簡要談低碳生活的好處。
      【寫作要求】 1．在作文中可以使用自己親身的經(jīng)歷或虛構(gòu)的故事，也可以參照閱讀材料的內(nèi)容但不得直接引用原文中的句子；
                                2．作文中不能出現(xiàn)真實姓名和學(xué)校名稱。
      【評分標準】概括準確，語言規(guī)范，內(nèi)容合適，篇章連貫。

Information from the pioneer spacecraft of the National Aeronautics and Space Administration (NASA) obviously proves the theory that the burning 900-degree Fahrenheit surface temperature of Venus (金星) is due to an atmospheric greenhouse effect caused mainly by a blanket of carbon dioxide. Such a greenhouse effect is created when energy in the form of sunlight easily passes through a planet’s atmosphere, warms is surface, and becomes heat radiation that is then held in by the atmosphere. The orbiting spacecraft has collected Venus’s atmosphere from top to bottom so that NASA’s scientists are able to prove the exact amount of sunlight received at various places in the planet’s atmosphere and on its surface. Measurements of atmosphere, temperature, and radiative heating foresee Venus’s surface temperature very exactly. The planet is closer to the Sun than it is to the Earth, and it has a thin atmosphere like the Earth’s but Venus atmosphere is made up of more than ninety percent carbon dioxide, compared to less than four percent in that of the Earth. Because of its higher percentage of carbon dioxide, Venus’s atmosphere receives much more heat radiation than the Earth’s does. Thus the Venus studies are believed to be important to the understanding of possible bad effects on Earth’s agriculture and sea levels that could result from the long-term use of fuels, which add carbon dioxide to the atmosphere．

Notes

1. atmospheric adj．大氣(中)的

2. carbon dioxide 二氧化碳

3．orbit vt.使(人造衛(wèi)星、宇宙飛船等)進入空間軌道；繞軌道運行

4．amount n．總數(shù)，總額

5．compare vt．把……比作(to)

1．Which of the following would be the most suitable title for the passage?

A．A New Theory

B．Measuring Planetary Temperatures

C．The Journey of Pioneer Spacecraft

D．The Greenhouse Effect on Venus

2．According to the passage, what happens to heat radiation on Venus?

A．It disappears at the planet’s surface．

B．It is received by the atmosphere．
