In July 1994 Jupiter, the largest planet in our solar system, was struck by 21 pieces of a comet (彗星). When the fragments (碎片) landed in the southern part of the giant planet, the explosions were watched by scientists here on earth. But what if our own planet was hit by a comet?
The year is 2094. It has been announced that a comet is heading towards the Earth. Most of it will miss our planet, but two fragments will probably hit the southern part of the Earth. The news has caused panic.
On 17 July, a fragment four kilometers wide enters the Earth's atmosphere with a huge explosion. About half of the fragment is destroyed. But the major part survives and hits the South Atlantic at 200 times the speed of sound. The sea boils and an enormous wave is created and spreads. The wall of water rushes towards southern Africa at 800 kilometres an hour. Cities on the African coast are totally destroyed and millions of people are drowned. The wave moves into the Indian Ocean and heads towards Asia.
Millions of people are already dead in the southern part of the Earth, but the north won't escape for long. Tons of broken pieces are thrown into the atmosphere by the explosions. As the sun is hidden by clouds of dust, temperatures around the world fall to almost zero. Crops are ruined. Wars break out as countries fight for food. A year later civilization has collapsed. No more than 10 million people have survived.
Could it really happen? In fact, it has already happened more than once in the history of the Earth. The dinosaurs were on the Earth for over 160 million years. Then 65 million years ago they suddenly disappeared. Many scientists believe that the Earth was hit by a space fragment. The dinosaurs couldn't survive in the cold climate that followed and they became extinct. Will we meet the same end?
【小题1】55.Which of the following is NOT TRUE according to the author's description of the disaster in 2094?
| A．The whole world becomes extremely cold |
| B．All the coastal cities in Africa are destroyed |
| C．The visit of the comet results in wars |

| A．Because they could only live in the warm climate |
| B．Because their extinction indicates future disasters |
| C．Because they once dominated the earth |

The economic growth that many nations in Asia and increasingly Africa have experienced over the past couple of decades has transformed hundreds of millions of lives – almost entirely for the better. But there’s a byproduct to that growth, one that’s evident – or sometimes less than evident – in the smoggy, smelly skies above cities like Beijing, New Delhi and Jakarta. Thanks to new cars and power plants, air pollution is bad and getting worse in much of the world, and it’s taking a major toll (伤亡人数，代价) on global health.
How big? According to a new analysis published in the Lancet, more than 3.2 million people suffered deaths from air pollution in 2010, the largest number on record. That’s up from 800,000 in 2000. And it’s a regional problem: 65% of those deaths occurred in Asia, where the air is choked by diesel soot (内燃发动机烟雾) from cars and trucks, as well as the song from power plants and the dust from endless urban construction. In East Asia and China, 1.2 million people died, as well as another 712,000 in South Asia, including India. For the first time ever, air pollution is on the world’s top – 10 list of killers, and it’s moving up the ranks faster than any other factor.
So how can air pollution be so damaging? It is the very finest soot – so small that it roots deep within the lungs and then enters the bloodstream – that contributes to most of the public – health toll of air pollution including death. Diesel soot, which can also cause cancer, is a major problem because it is concentrated in cities along transportation zones affecting overpopulated areas. It is thought to contribute to half the deaths from air pollution in urban centers. Fro example, 1 in 6 people in the U.S. live near a diesel – pollution hot spot like a rail yard, port terminal or freeway.
We also know that air pollution may be linked to other non – deadly diseases. Fortunately in the U.S. and other developed nations, urban air is for the most part cleaner than it was 30 or 40 years ago, thanks to regulations and new technologies like the catalytic converters (催化式排气净化器) that reduce automobile emissions. Govemments are also pushing to make air cleaner – see the White House’s move last week to further tighten soot standards. It’s not perfect, but we’ve had much more success dealing with air pollution than climate change.
Will developing nations like India eventually catch up? Hopefully – though the problem may get worse before it gets better. The good news is that it doesn’t take a major technological advance to improve urban air. Switching from diesel fuel to unleaded (无铅燃油) helps, as do newer and cleaner cars which are less likely to send out pollutants. Power plants – even ones that burn mineral fuels like coal – can be fitted with pollution – control equipment that, at a price, will greatly reduce smog and other pollutants.
But the best solutions may involve urban design. In the Guardian, John Vidal notes that Delhi now has 200 cars per 1,000 people, far more than much richer Asian cities like Hong Kong and Singapore. Developing cities will almost certainly see an increase in car ownership as residents become wealthier – and that doesn’t have to mean deadly air pollution. Higher incomes should also lead to tougher environmental regulations, which is exactly what happened in the West. We can only hope it happens before the death toll from bad air gets even higher.
【小题1】What tends to give rise to the highest death toll according to the passage?
| A．The lack of tight environmental protection standards. |
| B．The increasing numbers of the diesel cars and trucks. |
| C．The frighteningly high death rate from deadly cancer. |
| D．The world’s serious air pollution such as soot and dust. |
| A．consequence | B．solution | C．reform | D．design |
| A．the diesel soot is too small to be seen |
| B．the diesel soot is much too poisonous to breathe |
| C．the diesel soot roots in lungs and gets into blood |
| D．the diesel soot can also contribute to deadly cancer |
| A．the global economic growth is mainly to blame for air pollution and climate change |
| B．the developing countries are repeating the same mistakes as the developed ones made |
| C．the ecological situation and air pollution in India are becoming worse and worse |
| D．the unbeatable air is increasingly becoming a major killer throughout the world |
| A．the making of tougher environmental regulations alone is of little use |
| B．more sever regulations should be made to handle air pollution |
| C．the urban construction in western developed countries is the best choice |
| D．the pace of development has to be slowed down to reduce air pollution |

Why would an animal kill itself? It seems a strange question, and yet it is one that has made some scientists curious for a long time. For there is a kind of animal called lemming（旅鼠）, that periodically killed themselves together, and no one knows just why!
The small creatures which live in the Scandinavian mountains, feed on a diet of roots and special insects and live in nests they dig underground. When their food supply is large, the lemmings live a normal and undisturbed life.
However, when the lemmings’ food supply becomes too low to support the population, a singular migration（迁徙）begins. The lemmings leave their nests in groups. Great numbers of them begin to travel across the Scandinavian plains, a journey that may last weeks. The lemmings eat everything in their path, continuing their long march until they reach the sea.
The reason for what follows remains unbelievable to naturalists. Upon reaching the coast, the lemmings do not stop but swim by the thousands into the sea. Most stay afloat only a short time before they tire, sink and drown.
A common theory for this mass self-killing is that the lemmings do not realize that the ocean is such a huge body of water in their cross-country journey, the animals must cross many smaller bodies of water, such as rivers and small lakes. They may think that the sea is just another such swimmable path to go through. But no final answer has been found to the strange happening.
【小题1】The passage is mainly about______.
| A．how lemmings find food |
| B．why animals kill themselves |
| C．the lemmings’ self-killing |
| D．the food supply in the Scandinavian mountains |
| A．go mad from a lack of food |
| B．hope to find fish for food |
| C．decide to reduce the population |
| D．think they can cross the sea |
| A．Because they are the only animals that live in Scandinavia. |
| B．Because it is very unusual for animals to kill themselves. |
| C．Because of the amount of food they can eat on their march to the sea. |
| D．Because they can gather together in such huge numbers. |
| A．unusual | B．single | C．wonderful | D．common |

Many businesses today use conferences as a means of discussing new plans of the company. As people are paying more attention to the environment and green problems, more businesses are looking for ways to reduce their negative effect on the environment. Many businesses do this by using web conferencing.
Web conferencing is a technology that allows people to communicate more effectively over the Internet. It is an easy way of hosting and attending conferences without having to leave the office. Each of the people involved in a web conference will be posted an invitation to the conference with the time and date of the Web conference on it. When the conference is ready to begin, all participants (参与者) must sit at their computers and they will be connected over the Internet.
With Web conferencing all participants attend the conference from the comfort of their own desk. Obviously, in doing this no fuel is used in traveling to and from a conference, and less work time is taken up in attending a conference.
Any material to be used during the Web conference is simply e-mailed to all the participants before the conference. Participants can then either choose to print material or read it on screen. This not only saves paper but also greatly reduces mailing cost for the business.
As a conference hall or business center isn’t being used, it means that the only power that is used is the power used by the participants’ personal computers. Similarly conference organizers don’t have to arrange for food or overnight accommodation (住宿) for participants of their conferences. All this means that less energy is used.
Often in business some companies actively choose to do business with other companies that do many things to reduce their negative impact on the environment. And Web conferencing helps you show other businesses that you are willing to work hard for the green cause.
So Web conferencing is much cheaper and greener and more people are willing to host and attend a web conference.
【小题1】What is the passage mainly about?
A. Ways of protecting the environment.
B. B. Green benefits of Web conference.
C. Ways of hosting a Web conference.
D. Impacts of Web conferencing on costs.
【小题2】According to paragraph 1, many companies use Web conferencing because they ________.
| A．are interested in using any new technology |
| B．believe that Web conferencing is more convenient |
| C．want to do something to protect the environment |
| D．haven’t enough money to hold a traditional conference |
| A．will be e-mailed an invitation before the conference |
| B．are required to sit in the office together |
| C．will receive many paper materials |
| D．must have access to the Internet |
| A．Useless. | B．Environmentally friendly. |

50 years ago Barbie Millicent Roberts first appeared in the world of toys. Barbie, as everyone called her, has become the most successful toy in history. According to Barbie’s parents, the Mattel Company, 90% of all American girls between 3 and 10 have at least one Barbie at home.
In today’s world, however, Barbie is facing an identity crisis. There are many rivals on the market. For example, Bratz dolls, which are very popular among older girls, came to life seven years ago. They look more like today’s pop stars with heavy make-up（浓妆）and fashionable miniskirts. Today Bratz is a challenge for Barbie, because the company offers a wide variety of clothing, too.
It seems that Barbie has lost her appeal to older girls. “For younger girls playing with a Barbie is much fun, but when you get older you want something chic, says Alina Foley, a shop assistant in a New York toy store. Indeed, sales have been going down over the past year, partly because of the world’s economic crisis.
Barbie still has a lot going for her. More and more doll lovers all over the globe have become collectors. They trade Barbies or buy them on eBay. Others look for special and rare Barbie dolls, like Scarlett O’Hara from “Gone with the Wind”.
On the international market, Barbie remains number one. Although Mattel has been selling fewer Barbies in the United States over the past year, sales in other countries have been going up. In January Mattel opened its first Barbie store in Shanghai, where girls can shop, eat or even become their own fashion designer.
Barbie has changed her image many times over the past decades. Originally she worn blond pony tails and had bright red lips. In the 80s she changed to a more colorful new look.
For her 50th birthday Mattel is planning some big events. Fashion designers from all over the world have been called to make new clothes for Barbie. She is also scheduled to be a big star during the New York Fashion Week.
How long will Barbie stay on as a celebrity（名人）in the world of toy dolls? Hard to say, but 50 is definitely not the age to retire.
【小题1】The author mentions Bratz in Paragraph 2 in order to show that __________.
| A．even pop stars have their own favorite toy dolls |

Think of London and you will probably remember the bright red double-decker buses. Think of Thailand’s capital city, Bangkok, and the noisy tuk-tuks may come to mind. Think of San Francisco and you might see the city’s cable cars. 
Imagining what these cities would look like without those is difficult. They are symbols of these cities that make them different. However, these city symbols are not always so well loved by their city leaders. City leaders want what is best for their city, which often means the most modern transport.
In Bangkok, city leaders have banned(禁止)tuk-tuks because they consider them noisy and polluting. However, the ban has largely been unsuccessful as it has not changed Thai people’s love for the cheap tuk-tuks over taxis.
In London the city’s first ever mayor(市长)removed the red double-decker buses, which he thought were old fashioned. His plan worked, but Londoners were unhappy to lose the nice old buses they believed represented the best of their city. They made their unhappiness felt when the mayor came up for re-election. Most Londoners voted for his competitor, who promised to bring the bus back.
As for San Francisco, several cable cars are still in use but mainly as tourist attractions. They are too slow to be used for anything other than scenic trips.
City transport symbols may have a place in their city people’s hearts, but it seems they are increasingly out of step with the modern world. As Londoners have proved, their continued life depends on people’s willingness to fight for their survival.
【小题1】 What’s the author’s purpose of writing the first paragraph?
| A．To introduce some city transport symbols. |
| B．To explain why some cities are popular. |
| C．To talk about modern transport in some cities. |
| D．To attract more tourists to visit some cities. |
| A．the new mayor loves it |
| B．Londoners fought for it |
| C．it is an improved transport |
| D．it is popular with tourists |
| A．Only a few cable cars are still in use in San Francisco. |
| B．Bangkok city leaders tried to remove the cheap tuk-tuks. |
| C．The mayor who sold double-decker buses lost the re-election. |
| D．The new mayor will bring back improved double-decker buses. |
| A．Modern cities should remove old city transport symbols. |
| B．The writer thinks highly of the old city transport symbols. |
| C．Old city transport symbols face the problem of survival. |
| D．Tourist cities will lose their attraction without the symbols. |
