题型:不详难度:来源:
Within fifteen years Britain and other nations should be well on with the building of huge industrial complexes (结合)for the recycling of waste. The word "rubbish"  could lose its meaning because everything that goes into the dumps would be made into something useful. Even the most dangerous and un­pleasant wastes would provide energy if nothing else.
The latest project is to take a city of around half a million inhabitants and discover exactly what raw materials go into it and what go out. The aim is to find out how much of these raw materials could be provided if a plant for recycling waste were built just outside the city. This plant would recycle not only metal such as steel, lead and copper, but also paper and rub­ber.
Another new project is being set up to discover the best ways of sorting and separating the rubbish. When this project is complete, the rubbish will be processed like this: first, it will pass through sharp metal bars which will tear open the plastic bags in which rubbish is usually packed; then it will pass through a powerful fan to separate the lightest elements from the heavy solids; after that grounders and rollers break up everything that can be broken. Finally the rubbish will pass under magnets, which will remove the bits of iron and steel; the rubber and plastic will then be sorted out in the fi­nal stage.
The first full-scale giant recycling plants are, perhaps, fifteen years away. Indeed, with the growing cost of transpor­ting rubbish to more distant dumps, some big cities will be forced to build their own recycling plants before long.
1. The main purpose of the passage is ________.
A. to show us a future way of recycling wastes  B. to tell the importance of recycling wastes
C. to warn people the danger of some wastes    D. to introduce a new recycling plant
2. How many stages are there in the recycling process?
A. 3.                 B. 4.               C. 5.                          D. 6.
3. What is the main reason for big cities to build their own re­cycling plants?
A. To deal with wastes in a better way.  B. It’s a good way to gain profits.
C. It’s more economical than to dump wastes in some dis­tant places.
D. Energy can be got at a lower price. 
4. The first full-scale huge recycling plants ________.
A. have been in existence for 15 years   B. takes 15 years to build
C. can’t be built until 15 years later       D. will remain functioning for 15 years

What will people die of 100 years from now? If you think that is a simple question, you have not been paying attention to the revolution that is taking place in bio-technology(生物技术). With the help of new medicine, the human body will last a very long time. Death will come mainly from accidents, murder and war. Today’s leading killers, such as heart disease, cancer, and aging itself, will become distant memories.
In discussion of technological changes, the Internet gets most of the attention these days. But the change in medicine can be the real technological event of our times. How long can humans live? Human brains were known to decide the final death. Cells are the basic units of all living things, and until recently, scientists were sure that the life of cells could not go much beyond l20 years because the basic materials of cells, such as those of brain cells, would not last forever. But the upper limits will be broken by new medicine. Sometime between 2050 and 2100, medicine will have advanced to the point at which every 10 years or so, people will be able to take medicine to repair their organs. The medicine, made up of the basic building materials of life, will build new brain cells, heart cells, and so on—in much the same way our bodies make new skin cells to take the place of old ones.
It is exciting to imaging that the advance in technology may be changing the most basic condition of human existence, but many technical problems still must be cleared up on the way to this wonderful future. 
6. According to the passage, human death is now mainly caused by        .
A. diseases and aging                                 B. accidents and war

7. In the author’s opinion, today’s most important advance in technology lies in        .
A. medicine          B. the Internet     C. brain cells                     D. human organ
8. Humans may live longer in the future because        .
A. heart disease will be far away from us
B. human brains can decide the final death
C. the basic materials of cells will last forever
D. human organs can be repaired by new medicine
9. How long can humans live in the future according to the passage?
A. Over 100 years.                             B. More than 120 years.
C. About 150 years.                                   D. The passage doesn’t tell us.
10. We can learn from the passage that        .
A. human life will not last more than 120 years in the future
B. humans have to take medicine to build new skin cells now
C. much needs to be done before humans can have a longer life
D. we have already solved the technical problems in building new cells

It is not unusual to see your desk-mate yawn (打呵欠) as he complains that he didn"t have a good sleep the night before. Many teens don"t get enough sleep because they have too much homework, which keeps them up at night. Some teens cannot sleep at night even when they want to.
Studies show that during your teenage years, the body"s biological clock is reset, telling you to sleep later at night and wake up later in the morning.
But changes in the body clock aren"t the only reason teens lose sleep. Lots of people have insomnia (失眠). The most common cause of insomnia is stress. But all sorts of things can lead to insomnia. These include physical discomfort, emotional troubles and even sleeping environment. It"s common for everyone to have insomnia from time to time. But if it lasts for a month or more go and see a doctor.
Some people have a condition that causes stomach acid (酸) to move backward towards the chest. This produces the uncomfortable, burning feeling called heartburn. So even if the person doesn"t notice the feelings of heartburn because he is sleeping, he may feel tired the next day.
Most teens have nightmares sometimes. But, if they are frequent, a person"s sleep pattern can be seriously affected. The most common cause of nightmares is emotional problems, such as stress (压力) or anxiety. If you have them a lot, it"s a good idea to talk to a doctor.

Since life is short and the world is wide, the sooner you start exploring it, the better. Soon enough the time will come when you are too tired to move farther than the terrace of the best hotel. Go now.
No need, you may say, to tell that. But what I need to tell you is that you will meet with a surprising amount of opposition the moment you try to set out. Rubbish, you will reply. More people go abroad nowadays than ever before; never has travel, particularly among the young, been more strongly visit, of international exchanges. Perhaps not; but none of this, my dear young friends, is travel. Travel is not going on a round coach trip for $ 67 in all, or spending ten days at a hotel by the sea. Travel is when you want to see how much money and resources you have and then set out, alone or with chosen friends, to make an unhurried journey to a distant goal without a set date for your return.
Real travel, then, is independence in action, and is not liked by most parents. They don’t mind your going in a school party to Athens, because they know just where you are and when you’ll be back, and they can therefore permit you the imagination of freedom without for one second letting you beyond their control. But what they cannot bear is that you should travel all on your own, without giving them your address and return date. In fact, their fears are quite reasonable because that shows how much they love you. So in order to enjoy real travel and at the same time put your parents’ mind at ease. It would be really important for you to bear the following advice in mind.
5. Which statement is true according to the passage?
A. People travel more than before.                                  
B. Young people are encouraged to travel abroad.
C. People should not go on a round coach trip for $ 67.
D. Educational visits should not be encouraged as they are not real travel.
6.What does real travel mean according to the writer?
A. It means telling your parents nothing about the travel   
B. It means not knowing where you want to go.
C. It means traveling to a distant goal in an unhurried manner.  
D. It means traveling without any plan.
7. Your parents allow you to travel in a school party because ________.
A. they want you to be truly free                       B. you are still under their control
C. they don’t have time to travel with you          D. they know it’s good for you
8. According to the writer, when you do real traveling, you should ________.
A. never mind how worried your parents are             
B. give your parents your address and return date
C. tell your parents details about your travel       
D. not let your parents worry about you

We now think of chocolate as sweet, but once it was bitter. We think of it as a candy, but once it was a medicine. Today, chocolate can be a hot drink, a frozen dessert, or just a snack. Sometimes it’s an ingredient(配料) in the main course of a meal. Mexicans make a hot chocolate sauce called mole and pour it over chicken. The Mexicans also eat chocolate with spices(香料) like chili peppers.
Chocolate is a product of the tropical cacao tree. The beans taste so bitter that even the monkeys say “Ugh!” and run away. Workers must first dry and then roast the beans. This removes the bitter taste.
The word “chocolate” comes from a Mayan word. The Mayas were an ancient people who once lived in Mexico. They valued the cacao tree. Some used the beans for money, while others crushed them to make a drink.
When the Spaniards came to Mexico in the sixteenth century, they started drinking cacao too.Because the drink was strong and bitter, they thought it was a medicine. No one had the idea of adding sugar. The Spaniards took some beans back to Europe and opened cafes. Wealthy people drank cacao and said it was good for the digestion.
In the 1800s, the owner of a chocolate factory in England discovered that sugar removed the bitter taste of cacao. It quickly became a cheap and popular drink. Soon afterwards, a factory made the first solid block of sweetened chocolate. Later on, another factory mixed milk and chocolate together. People liked the taste of milk chocolate even better.
Besides the chocolate candy bar, one of the most popular American snacks is the chocolate chip cookie. Favorite desserts are chocolate cream pie and, of course, an ice cream sundae with hot fudge sauce.
