Some people in Manchester, Britain, will soon be paying for goods and services with so-called “smart” credit cards. These cards are more secure than the traditional magnetic-strip version and can be used to travel on buses, check bank accounts and do shopping.

The Manchester project is one of the biggest smart card schemes in the world. Every time people use the cards on a bus or train, the fare is deducted (reduced) from the value of the card. When they have no credit left, the cards can be recharged at a local shop.

A smart card looks just like a normal plastic card but it has a silicon chip in it. It is possible for the same silicon chip to perform a number of different functions, so one plastic card in your pocket could do a large number of different jobs. The card has much more memory space than a magnetic-strip card, so many more things can be recorded on it.There are two types of smart cards. One is the contact card which is used in the same way as a magnetic-strip card.

Information is transferred by running the card through a narrow opening in an electronic reader. In the slot, electronic probes make contact with the magnetic-strip or silicon ship and read the information. The other type is the contactless smart card where the electronic reader communicates with the card by short-range radio waves. This makes the card quicker and more convenient to use because it does not have to leave your wallet. It is also more reliable as it is not easily influenced by scratches or dirt. However, the biggest advantage that smart cards have over magnetic-strip cards is that they are more secure. They are much more difficult to make than conventional cards and they have to be made by specially trained manufacturers. In addition, they have a large number of extra security features on them and if a smart card gets lost or stolen a quick phone-call to the distributor ensures that its individual number is made invalid and unreadable. This can be done more quickly than with a magnetic-strip card.

Directions: Read the following passage. Complete the diagram by using the information for the passage. Write NO MORE THAN 3 WORDS for each answer.

Aids today

Aids, the short form for acquired immune deficiency syndrome, is caused by a virus called HIV, which enters a person’s blood and attacks the body’s immune (免疫的) system. There is no cure for HIV or Aids, and after a person has been infected, he or she will always carry the virus. Sometimes, infected people have no outward symptoms.

HIV and Aids are spreading across the world at a frightening rate, with about 14,000 people being infected daily. The virus is spread in three ways -- through unprotected sex, blood-blood contact and mother-to-child transmission. Unprotected sex is the most common way that the virus is spread, accounting for 75 percent of adult infections worldwide.

Although many people are familiar with Aids and how it is transmitted, more than a few people hold the view that HIV and Aids are an African problem because the infection rates there are very high. However, HIV and Aids are a problem all over the world. Since the disease was discovered in the 1980s, it has become a serious problem in many places, infecting over 60 million people worldwide. According to the World Health Organization estimates from 2005, more than 4 million children had died from Aids, and more than 14 million children had lost their parents to Aids. All of this makes it clear that something must be done to stop this deadly disease.

The government is working hard to control the Aids epidemic and has opened labs to test and monitor the disease. In 2003, the government also started providing free drugs for Aids patients in need.

The United Nations has been very involved in fighting HIV and Aids around the world for many years now. UNAIDS, an organization founded in 1996, helps prevent the spread of Aids. The work includes providing infected people with help from doctors and testing for people. The organization also offers programs that teach Aids prevention to young people and sets up treatment centers.

Blind imitation (模仿)is self-destruction. To those who do not recognize their unique worth， imitation appears attractive；to those who know their strength. Imitation is unacceptable.

In the early stages of skill or character development, imitation is helpful. When I first learned to cook, I used recipes (菜譜) and turned out some tasty dishes. But soon I grew bored. Why follow someone else’s way of cooking when I could create my own? Imitating role models is like using training wheels on a child’s bicycle; they help you get going, but once you find your own balance, you fly faster and farther without relying on them.

In daily life, imitation can hurt us if we subconsciously (下意識(shí)地) hold poor role models. If, as a child, you observed people whose lives were bad, you may have accepted their fear and pain as normal and gone on to follow what they did. If you do not make strong choices for yourself, you will get the results of the weak choices of others.

In the field of entertainment, our culture glorifies celebrities. Those stars look great on screen. But when they step off screen, their personal lives may be disastrous. If you are going to follow someone, focus on their talent, not their bad character or unacceptable behaviors.

Blessed is the person willing to act on their sudden desire to create something unique. Think of the movies, books, teachers, and friends that have affected you most deeply. They touched you because their creations were motivated by inspiration, not desperation. The world is changed not by those who do what has been done before them, but by those who do what has been done inside them. Creative people have an endless resource of ideas. The problem a creator faces is not running out of material; it is what to do with the material knocking at the door of imagination.

Study your role models, accept the gifts they have given, and leave behind what does not serve you. Then you can say,” I stand on the shoulders of my ancestors tragedies and declare victory, and know that they are cheering me on.

1.Imitation proves useful when you .

A. know you are unique

B. lose the balance of life

C. begin to learn something new

D. get tired of routine practice

2.To avoid the bad result of imitation, we should________.

A. forget daily fear and pain B. choose the right example

C. ask others for decisions D. stay away from stars

3.The trouble a creator faces is .

A. the lack of strong motivation

B. the absence of practical ideas

C. how to search for more materials

D. how to use imagination creatively

4.What is the author’s purpose in writing this passage?

A. To highlight the importance of creatively.

B. To criticize the characters of role models.

C. To compare imitation with creation.

D. To explain the meaning of success.

All of us eat every day, but most of us don’t understand nutrition(營(yíng)養(yǎng)). How much do you know about good nutrition? Are the following statements true or false?

1. People who don’t eat meat can stay healthy.

True. As long as people eat enough milk, eggs and meat alternates(替代物), they can get enough protein.

2. Fresh vegetables cooked at home are always more nutritious than canned vegetables.

False. The difference depends more on how vegetables are prepared than whether they are fresh or canned. Vegetables cooked in too much water can lose a large quantity of vitamins.

3. Food eaten between meals can be just as good for health as food eaten at regular meals.

True. Nutritional value depends on what types of food you eat, not when you eat them. Eating an egg or an orange between meals can contribute to a good diet.

4. Taking extra vitamins beyond the recommended daily allowances won’t give you more energy.

True. It’s widely believed that extra vitamins provide more energy. But taking more than the baby needs doesn’t make it function better, just as overfilling your gas tank doesn’t make your car run better.

5. Natural vitamins are better supplements(補(bǔ)充)for the diet than synthetic vitamins.

False. There is no difference. A vitamin has the same properties(性質(zhì))and specific chemical structure whether made in a laboratory or taken from plant or animal parts.

6. Older people need the same amount of vitamins as younger people.

True. Older people need the same quantity of vitamins as younger people although they need fewer calories. Certain illnesses raise the requirements for some vitamins, but that is true for the young as well as the old.

7. Food grown in poor soil is lower in vitamins than food grown in rich sold.

False. The vitamins in our foods are made by the plants themselves. They don’t come from the soil.

However, the minerals in a plant depend on the minerals in the soil.

If you have answered these questions correctly, you can say you know much about food and nutrition by today’s standards. But remember that nutrition is a growing science and that may be aged as new information is obtained.

1.The main purpose of the passage is to .

A. list today’s standards of some food and nutrition

B. introduce what should be eaten and what not

C. explain what is helpful to your health and what is not

D. test our nutrition IQ by judging the problems listed

2.From the surrounding words and sentences we know that the underlined phrase “contribute to” means .

A. help to bring about B. take the place of

C. make room for D. turn to

3.The underlined word “synthetic” most probably means in Chinese.

A.不同的 B.特別的

C.合成的 D.天然的
