题目内容

The plastic identification cards carried by all Chinese citizens over 16 are to be replaced with electronic cards.

The new cards, which most people will have by 2007, contain a microchip(微芯片) on which personal information is stored. This can be checked against databases(资料库) kept by the government.

“The information will be locked into the card so that people won’t be able to use false identities.”said Ren Tianbu, a security official in Shenyang.

China’s present plastic identity cards were introduced 17 years ago, and many other countries use a similar system. However, the information shown on a card differs from nation to nation. Most ID cards show the holder’s name, sex, date of birth and photograph.

Germany, France and Spain all use ID cards, but there are some developed nations who dislike the idea. The US, Canada, New Zealand, Australia, Sweden and Britain are among those with no national ID card. However, some of the countries have ID cards for particular uses. For example, Australia and the United States use a driving license to identify people.

Identity cards are introduced for a variety of reasons. Race, politics and religion were often at the heart of older ID systems. In recent years, though, ID cards have been linked to national information databases, which form the basis of how a government manages a country.

The US, Britain and some other countries are considering a national ID system as a way of preventing terrorist attacks.

However, such plans have been met with strong resistance by those who believe identity cards work against human rights and personal information.

“ID cards make us suspects, not citizens,” said UK human rights group Liberty.

1.What is one of the differences between China’s new and present ID cards?

A．The new ones contain different personal information.

B．The present ID cards are easier to copy.

C．Even little kids can have the new ID cards.

D．The information on present ID cards isn’t in the databases kept by the government.

2.Which of the following countries does not have an ID card system?

A．France.　　　　　 B．Spain.　　　　 C．Sweden.　　　 D．Germany.

3.What is the main reason why government use ID card systems nowadays?

A．To prevent terrorist attacks.　　　　

B．To fight against crimes.

C．To support government services.　　

D．To have more control on its citizens.

We produce 500 billion of plastic bags in a year worldwide and they are thrown away polluting oceans, killing wildlife and getting dumped in landfills where they take up to 1,000 years to decompose. Researchers have been unsuccessfully looking for a solution.
The 16-year-old Canadian high school student, Daniel Burd, from Waterloo Collegiate Institute, has-discovered a way to make plastic bags degrade(降解) in as few as 3 months, a finding that won him first prize at the Canada Wide Science Fair, a ＄10,000 prize, a ＄20,000 scholarship, and a chance to revolutionize a major environmental issue.
Burd’s strategy was simple: Since plastic does eventually degrade, it must be eaten by microorganisms (微生物). If those microorganisms could be identified, we could put them to work eating the plastic much faster than under normal conditions.
With this goal in mind, he grounded plastic bags into a powder and concocted(调制) a solution of household chemicals, yeast(酵母) and tap water to encourage microbes growth. Then he added the plastic powder and let the microbes work their magic for 3 months. Finally, he tested the resulting bacterial culture on plastic bags, exposing one plastic sample to dead bacteria as a control. Sure enough, the plastic exposed to the live bacteria was 17% lighter than the control after six weeks.
The inputs are cheap, maintaining the required temperature takes little energy because microbes produce heat as they work, and the only outputs are water and tiny levels of carbon dioxide.
“Almost every week I have to do chores and when I open the closet door, I have piles of plastic bags falling on top of me. One day, I got tired of it and I wanted to know what other people are doing with these plastic bags. The answer: not much. So I decided to do something myself.” Said Daniel Burd.

阅读下面短文，从每题所给的A、B、C和D项中选出最佳选项，并在答题卡上将该项涂黑。
In 1993, New York State ordered stores to charge a deposit on beverage (="drink)" containers. Within a year, consumers had returned millions of aluminum cans and glass and plastic bottles. Plenty of companies were eager to accept the aluminum and glass as raw material for new products, but because few could figure out what to do with the plastic, much of it wound end up buried in landfills(垃圾填埋场). The problem was not limited to New York. Unfortunately, there were too few uses for second-hand plastic.
Today, one out of five plastic soda bottles is recycled in the United States. The reason for the change is that now there are dozens of companies across the country buying discarded plastic soda bottles and turning them into fence post, paint brushes, etc.
As the New York experience shows, recycling involves more than simply separating valuable materials from the rest of the rubbish. A discard remains a discard unti1 somebody figures out how to give it a second life — and until economic arrangements exist to give that second life va1ue.Without adequate markets to absorb materials collected for recycling, throwaways actually depress prices for used materials.
Shrinking landfill space and rising costs for burying and burning rubbish are forcing local governments to look more closely at recycling. In many areas, the East Coast especially, recycling is already the least expensive waste-management option. For every ton of waste recycled, a city avoids paying for its disposal, which, in parts of New York, amounts to savings of more than $100 per ton. Recycling also stimulates the local economy by creating jobs and reduces the pollution control and energy costs of industries that make recycled products by giving them a more refined raw material.
1. What regulation was issued by New York State concerning beverage containers?
A. A fee should be charged on used containers for recycling.
B. Throwaways should be collected by the state for recycling.
C. Consumers had to pay for beverage containers and could get their money back on returning them.
D. Beverage companies should be responsible for collecting and reusing discarded plastic soda bottles.
2. The returned plastic bottles in New York used to        .
A. be turned into raw rnateria1s
B. be separated from other rubbish
C. have a second-life value
D. end up somewhere underground
3. The key problem in dealing with returned plastic beverage containers is         .
A. how to reduce their recycling costs
B. to sell them at a profitable price
C. how to turn them into useful things
D. to lower the prices for used materials
4. Recycling has become the first choice for the disposal of rubbish because         .
A. recycling causes litt1e pollution
B. other methods are more expensive
C. recycling has great appeal for the jobless
D. local governments find it easy to manage
5. It can be concluded from the passage that          .
A.    recycling is to be recommended both economically and environmentally
B. local governments in the U. S. can expect big profits from recycling
C. rubbish is a potential remedy for the shortage of raw materials
D. landfills will sti1l be widely used for waste disposal

I will tell you the truth about plastic bags－the positive and the negative sides and provide a solution to this problem. Whether it is a shopping bag, a food bag or a trash bag, they are all made of plastic bags. Grocery store owners are very generous in using plastic bags. They place the fruit in one bag and drop the box of milk in another. Ever wonder why?
The positive side of plastic bags
Grocery stores, shopping centres, and restaurants are not thrifty in using and giving out plastic bags because they cost no more than a cent each, while a paper bag costs four cents. Plastic bags are produced so cheaply and massively（大量地）that they are used by 80% of store owners. In addition, they are light and very easy to carry and store.
The production of plastic bags has increased greatly over the last 20 years and producers of plastic bags are making large profits. However, the negative side of plastic bags is becoming well-known. More people are now getting worried that the earth is becoming a victim of the plastic bag success story.
The negative side of plastic bags
While production and consumption（消费）of plastic bags is good for business, it is not so for our Mother Earth. They have resulted in an increase in the amount of litter found floating in water or in the streets where we live.
Plastic storage bags, after usage, usually go to landfills（垃圾填埋地）as trash bags. They make the oceans poison sea animals. They give off toxins（毒素）when burned. They simply pollute the ground, air and water.
That is the true cost of plastic bags, and it looks like it is more than a cent. These are very alarming concerns and proper action needs to be taken.
【小题1】According to Paragraph 3, plastic bag producers ________.

A．are now worried that the earth will become a victim of plastic bags

Since its invention 100 years ago, plastic , the superstar of the technological age, has become ugly and ungreen . But that’s about to change. An exhibition at London’s Science Museum this week could put it back on the cutting edge of science.

Have you ever hesitated in donating blood? The invention of “plastic blood” might make you feel better.

British scientists are working on the artificial blood as a replacement for real blood in emergency situations. It is made of plastic molecules(分子 ) and can join oxygen and transport it around the body. As a red, honey-like glue , plastic blood can be carried around conveniently . You just add water to make as much blood as you need.

The cells of our body are strict about what molecules the let in and out . For example , if we inject protein or DNA directly into the body, our immune ( 免疫 ) SYSTEM WILL DESTROY IT BEFORE IT REACHES THE CELLS.

To get around this , a British scientist has created drug-carrying plastic balls that fool the body into thinking they are natural. Once inside the cell, their contents are spread out through a small controlled explosion.

Skin transplants are widely done these days. But removing a piece of skin from, say , the bottom to plant it on the face can hurt and be troublesome.

The British company, Celltran, is working on plastic skin. Using plastic, they plan to take a small piece of the patient’s skin and grow it into an extra lay of skin on top of the plastic. a

The plastic feels similar to skin, so skin cells like to grow on it. The plastic then gradually disappears, without any reaction or infection .

1. What would be the best title for the text?

A. The superstar of technological age

B. An exhibition at London’s Science Museum

C. No more “white pollution”

D. Plastic takes on a new life

2. Which of the following will be on display at the exhibition at London’s Science Museum?

A. Plastic cells B. Plastic skin

C. Plastic molecules D. Plastic transplants

3. The phrase “get around “ in Paragraph 5 means closest to ______.

A. Plastic blood will be injected into the body in drug-carrying plastic balls

B.The plastic skin will remain a part of the new skin

C. Plastic blood will take the place of real blood

D. Plastic blood contains a lot of water

With fifteen years Britain and other nations should be well on with the building of big industrial plants for the recycling of waste. The word rubbish could lose its meaning because everything which goes into the dustbin would be made into something useful. Even the most dangerous and unpleasant wastes would provide energy of nothing else.

The latest project is to take a city of around half a million citizens and discover exactly what raw (未经加工的) 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 as well.

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 treated 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 (元素) from the heavy solids; after that rollers will break up everything that can be broken. Finally, the rubbish will pass under magnets (磁铁), which will remove the bits of iron and steel; the rubber and plastic will then be sorted out in the final step.

The first full-scale (全方位的) big recycling plants are perhaps fifteen years away. Indeed, with the growing cost of transporting rubbish to more distant dustbins, some big cities will be forced to build their own recycling plants before long.

1.The underlined phrase “be well on with…” most probably means __ .

A. have completed what was started B. get ready to start

C. have achieved a great deal in D. put an end to

2. What is NOT mentioned as a part of the recycling process (过程) described in

Paragraph 3?

A. Breaking up whatever is breakable.

B. Sharpening metal bars.

C. Separating light elements from the heavy ones.

D. Sorting out small pieces of metal.

3.What’s the main reason for big cities to build their own recycling plants?

A. To deal with wastes more economically.

B. To protect the environment from pollution.

C. To get raw materials locally.

D. To get advantage from those plants.

4.The passage is mainly about .

A. a cheap way to get energy B. the position of recycling plants

C. new ways of recycling wastes D. the probability of city environment
