The year is 2094. It has been announced that a comet (彗星) is heading towards the Earth. Most of it will miss our plant, but two pieces will probably hit the southern half of the Earth.
On 17 July, a piece four kilometers wide enters the Earth’s atmosphere(大气层) with a massive explosion. About half of the piece is destroyed, but the remaining part hits the South Atlantic at 200 times the speed of sound. The sea boils and a huge hole is made in the sea bed. Huge waves are created and spread outwards from the hole. The wall of water, a kilometer high, rushes towards southern Africa at 800 kilometers an hour. Cities on the African coast are totally destroyed and millions of people are drowned.
Before the waves reach South America, the second piece of the comet lands in Argentina. Earthquakes and volcanoes are set off in the Andes Mountains. The shock waves move north into California and all around the Pacific Ocean. The cities of Los Angeles, San Francisco and Tokyo are completely destroyed by earthquakes. Millions of people in the southern half of the earth are already dead, but the north won’t escape for long. Because of the explosions, the sun is hidden by clouds of dust, and temperatures around the world fall to almost zero. Crops are ruined. The sun won’t be seen again for many years. Wars break out as countries fight for food. A year later, no more than 10 million remain alive.
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 piece of object in space. The dinosaurs couldn’t live through the cold climate that followed and they died out. Will we meet the same end?What is mainly described in the passage?
| A．An event of imagination. |
| B．A scientific adventure. |
| C．A research on space. |
| D．A historic discovery. |
When the first piece hits the South Atlantic , it causes _____

The only survivor of one of the two Sandy Hook Elementary School first-grade classrooms where Adam Lanza shot and killed 20 children tricked the gunman by playing dead, the girl’s pastor （牧师） said．

“The mom told me — and I thought this was very insightful （有深刻见解的） — that she was suffering from what she felt was survivor’s guilt because so many of her friends no longer have their children but she has hers,” Solomon said how the girl’s mother and father are handling the trauma （伤害）．“I don’t know whether I would have the type of faith that they have if the same thing happened to me．”How did the girl manage to avoid being shot?

Human beings have used tools for a very long time. In some parts of the world you can still find tools that people used more than two million years ago. They made these tools by hitting one stone against another. In this way, they broke off pieces from one of the stones. These chips of stone were usually sharp on one side. People used them for cutting meat and skin from dead animals, and also for making other tools out of wood. Human beings needed to use tools because they did not have sharp teeth like other meat eating animals, such as lions and tigers. Tools helped people to get food more easily.
Working with tools also helped to develop human intelligence. The human brain grew bigger, and human beings began to invent more and more tools and machines. The stone chip was one of the first tools that people used, and perhaps it is the most important. Some scientists say that it was the key to success of mankind.
Since 1960 a new kind of tool has appeared. This is the silicon chip (硅芯片). It is smaller than a finger nail, but it can store lots of information. It is an electronic brain. Every year these chips get cleverer, but their size gets smaller, and their cost gets less. They are used in watches, calculators and intelligent machines that we can use in many ways. In the future we will not need to work with tools in the old way. Machines will do everything for us. People will have plenty of spare time. But what will they do with it?
Human beings used stone chips for more than two million years, but human life changed very little in that time. We have used silicon chips for only a few years, but life is changing faster every day. What will life be like twenty years from now? What will the world be like two million years from now?The silicon chip is mentioned in the passage to ________.
| A．show the changes of tools |
| B．introduce a new kind of tool |
| C．give an example of using tools |
| D．compare the effects of two kinds of tools |
At the end of the passage the author seems to suggest that life in future is ________.
| A．out of order | B．less colorful |
| C．hard to predict | D．full of meanings |
A large number of women in Western European countries wish that they were born men. The number is said as high as 60% in West Germany.

Anne Harper has a very good job for an international oil company. She also believes in “Women’ s Liberation(解放)”.
“I don’t wish that I were a man,” she says, “and I don’t think many women do. But I do wish that people would stop looking down upon us women. At work, for example, we often do the work that men do but get paid less. There are still a lot of jobs that are usually the best ones and open only to men.

We know that cigarette smoking kills． So, producers made electronic cigarettes as a safer smoking choice - safer than tobacco． Although e-cigarettes contain the drug nicotine like cigarettes, they do not use tobacco and you do not light them． They are powered by battery （电池）．
However, if e-cigarettes are so safe, why has the United States Center for Disease Control（CDC） seen an increase in telephone calls about e-cigarette poisonings?
The answer is children． Most of the calls are from people worried about children who have played with the devices, In the period of one month this year, the Center said 215 people called the Center with e-cigarette concerns． More than half of these calls were for children aged five and younger． The devices had made them sick．
Tim McAfee is director of the Center's Office on Smoking and Health, He says the problem is regulation． Meaning, the U．S． federal government does not control e-cigarettes even though they contain liquid nicotine． Mr．McAfee adds that liquid nicotine is a well-known danger． Mr．McAfee explains that nicotine poisoning happens when it gets into the skin, gets into the eyes or is swallowed． It can cause stomach pain or a sense of unbalance． And too much nicotine can kill,
Tim McAfee says e-cigarettes do not create the level of risk to people that tobacco products do．He notes that almost 500,000 Americans die each year from cigarettes． "So, cigarettes are the winner in that contest．" E-cigarettes do not contain hundreds of harmful chemicals that are found in real cigarettes． So, the U．S．Surgeon General Boris D． Lushniak has suggested that e-cigarettes may be a useful tool for adults trying to end their tobacco use．
But McAfee worries that teenagers may think electronic cigarettes are harmless． They could become addicted to the nicotine and then start smoking real cigarettes． In other words, he fears that for young people fake e-cigarettes could be a "gateway" to the real thing．It can be inferred from the passage that______．
A． the CDC wants to develop a better type of e-cigarettes
B． the government is in favor of the use of e-cigarettes
C． Surgeon General Boris D． Lushniak is a heavy smoker
D． smokers most probably can't quit smoking using e-cigarettesWhat is Tim McAfee's opinion about smoking?
| A．Adults should use harmless e-cigarettes． |
| B．Smoking e-cigarettes can make a person sick． |
| C．He claims that regulations should be made to ban smoking． |
| D．He is concerned about the teens using e-cigarettes． |
