試題分析：這篇短文主要介紹了彗星的組成部分，為什么叫做彗星。彗星有一部分會(huì)移出我們的視線再也不回來(lái)，但又有一部分會(huì)定期回來(lái)像哈雷彗星。
小題1:根據(jù)后文It shines from the sunlight it reflects (反射)可知彗星像行星一樣本身不發(fā)光。故選C。
.小題2:根據(jù)后文These clouds, together with the dust, form a long tail.可知這些云加上塵埃形成長(zhǎng)長(zhǎng)的尾巴�？芍衔臅�(huì)提到云的形成故選D。
小題3:上文許多人可能見(jiàn)過(guò)彗星。根據(jù)句子的轉(zhuǎn)折詞.However，可知與上文發(fā)生轉(zhuǎn)折。故選B。
小題4:根據(jù)后文Others keep coming back at regular times. 其他的彗星會(huì)定期回歸可知前文再說(shuō)一些彗星。故選B。
小題5:是非判斷題。根據(jù)Others keep coming back at regular times.可知彗星會(huì)定期回歸。故B項(xiàng)是錯(cuò)誤的。

Antarctica is in the most southern part of the world. It is like nowhere else on the earth. It is much larger than Europe, and nearly twice the size of Australia. Antarctica is the coldest and windiest place in the world, even colder and windier than the North Pole. In summer, the sun shines for twenty-four hours a day, but in winter it’s completely dark for about three months. Very few plants grow there, but there is some wildlife, including whales, seals and penguins.
When Captain James Cook traveled around Antarctica in the 1770s by ship, he found no one living there. Today, a few scientists work in Antarctica, but they only spend a short time there.
Many scientists are studying the ozone layer, which is getting thinner and thinner worldwide. The biggest “hole” is above Antarctica, and weather there is getting warmer. Scientists think that this cold and lonely place can teach us a lot about the earth and how to keep the earth safe.

This past month saw one of the most devastating storms in history brings death and destruction on the Philippines. The number of lives lost is still being calculated, but it is already sitting above five thousand. In the flurryof news about the storm and its after－math, the cries of “I told you so” from environmentalists rang out loud and clear.
　　These scientists were especially vocal during the United Nations Climate Change Conference, which just wrapped up in Warsaw, Poland. The timing of the conference and Typhoon Haiyan was an eerie coincidence, but perhaps the concurrence offered a wakeup call for all.
　　Christiana Figures, Executive Secretary of the UN Framework Convention on Climate Change (UNFCCC) said, “We are witnessing ever more frequent extreme weather events, and the poor and vulnerable are already paying the price.”
　　Scientists claim that storms like Typhoon Haiyan are an inevitable result of the effect greenhouse gases are having on our environment. Environmental analysts claim that rising temperatures around the globe and changing weather patterns are all part of the same problem.
　　This isn’t breaking news. We’ve heard the warnings for years. The UN has been hosting the Climate Change Conference since1995.But the changes that need to be made are huge. Added to this, the developed nations and developing countries have competing interests that are difficult to settle. The issue of who takes responsibility becomes difficult to resolve.
　　We may feel far away from Poland and resolving conflicts between countries, but we mustn’t feel far away from the issue. When we watch neighboring countries suffer in severe weather, when we hear reports of increasing global temperatures, when we walk outside and find it difficult to breathe the Shanghai air, we know we have a very real problem. So what are we going to do about it? Are we making every-day choices that can have a positive impact? Are we reducing our carbon footprint? Are we choosing to walk, ride a bicycle or take public transportation instead of a car? Are we recycling? Are we turning off the lights and electronics whenever possible?
　　The problem is complex, but saving our earth starts with each of us taking simple steps.
小題1:What is the most terrible typhoon in 2013? It is _________.
A．HaiyanB．BebincaC．DanasD．Cimaron
小題2:Warsaw isn’t in Poland，is it?
A．Yes, it isB．No, it isn’tC．Yes, it isn’t D．No, it is
小題3:How many years have we heard the warnings? For nearly ______years.
A．21B．18C．19D．20
小題4:Which of the following is NOT FALSE?
A．The environment is worse and worse and we have no ideas about it.
B．The environment is worse and we needn’t do anything about it.
C．Saving our environment is not so complex.
D．The environment is a big problem and we must take simple steps
