What is your favorite color? Do you like yellow, orange or red? If you do, you must be an optimist (乐观者), a leader, an active person who enjoys life, people and excitement. Do you prefer grays (灰色) and blues? Then you are probably quiet, shy and you would rather follow than lead. If you love green, you are strong-minded and determined (意志坚定的). You wish to succeed and want other people to see you are successful. At least this is what psychologists (心理学家) tell us, and they should know, because they have been seriously studying the meaning of color preference (爱好), and the effect (影响) that colors have on human beings. They tell us that we don't choose our favorite color as we grow up. If you happen to love brown, you did so as soon as you opened your eyes, or at least as soon as you could see clearly.

A yellow room makes us feel more cheerful (开心的) and more comfortable (舒服的) than a dark green one, and a red dress rings warmth and cheer to the saddest winter day. On the other hand, black is depressing (压抑). Light and bright colors make people not only happier but more active. It is a fact that factory workers work better, harder, and have fewer accidents when their machines are painted orange rather than black or dark gray.

Remember, then, that if you feel low, you can always brighten your day or your life with a new shirt or a few colorful things. Remember also that you will know your friends and your enemies better when you find out what colors they like and dislike. And don't forget that anyone can guess a lot about your character when you choose a piece of handkerchief.

1.According to this passage, _________.

A. one can choose his color preference

A. colors do have effect on our moods(情绪)

B. colors may have effect on our work and study

C. light and bright colors make people happy

D. you can know your friends better by the colors they like or dislike

A. one's color preference shows one's character

C. psychologists have been studying the meaning of color preference

On the other hand, black is depressing(令人压抑的). There was a black bridge over the Thames River, near London. The number of people who killed themselves on that bridge used to be larger than on any other bridge in the area -- until it was repainted green.

Light and bright colors make people not only happier but also more active. In the factory, the workers will work better, harder, and have fewer accidents when their machines are painted orange rather than black.

Have you ever posted letters to your friends or parents? If so, you must have put stamps on the letters before you sent them. But, how did people receive letters before stamps were invented, and who came up with the idea of using stamps?

In the past, stamps and envelopes were not used. When people wanted to send a letter, they would close the paper with a seal（封印）. The person who got the letter had to pay for it. Because costs at that time were very high, most people refused to accept letters. In fact, the sender would often place secret marks on the outside of the letter. The person who was sent the letter would read the secret message. Then, they would refuse to accept the letter and did not have to pay for it.

In Britain, Sir Rowland Hill introduced the “Post Office Reforms” in 1837. He decided that letters could go to any place in the country for a penny even if the letter had to go far away. The cost was to be paid by the sender of the letter. Payment was recorded by placing a small piece of coloured paper on the letter, the stamp! On May 6,1840, the first stamp called the “Penny Black” was born. Because the stamp was printed in black, the stamp became known as the “Penny Black”. This is now the world’s most famous stamp. This new system spread fast.

1.The best title for this passage should be______

2.Before stamps were used,______ would pay for the letter.

3.The first stamp was made______.

4.Which of the following is true about the first stamp of China?

If you are taking vitamin supplements to reduce your risk of heart disease or cancer, a group of health experts want you to know that those vitamins may actually increase your risk of cancer.

The US Preventive Services Task Force came to this conclusion after reviewing dozens of studies.

Nearly half of adults in the US take at least one vitamin or mineral supplement on a regular basis. These pills are advertised as a way to promote general health. In some cases, producers promote them as cancer fighters and heart protectors.

Studies in animals and in laboratory dishes suggest that oxidative(氧化性的) stress contributes to diseases like cancer and heart disease. If so, there is a reason to believe that antioxidants—including beta－carotene, vitamins A, C, and E—could be useful as preventive medicines.

But when the Task Force examined the medical evidence on vitamins, it found “inadequate(不充分的) evidence” to support the claims that vitamin and mineral supplements benefit healthy adults.

“Cardiovascular(心血管的) disease and cancer have a significant health impact in America, and we all want to find ways to prevent these diseases，” Dr. Virginia Moyer, who heads the Task Force, said in a statement. But so far, she added, the medical evidence does not show that taking vitamins is helpful in this aspect.

However, the Task Force did find “adequate evidence” that people with a raised risk for lung cancer actually increase their risk further by taking beta－carotene, a precursor of vitamin A.

The Task Force recommendations of taking vitamins regularly apply to healthy adults aged 50 and older who don't have “ special nutritional needs”. The advice does not apply to children, women who are pregnant or may become pregnant, people with chronic illnesses, or people who have to take supplements because they can't get all their essential nutrients from their diet.

1.Studies in animals and in laboratory dishes find out________．

A. adequate evidence that taking vitamins are helpful for treating lung cancer

B. cardiovascular disease spreads very fast in America

C. oxidative stress can lead to heart disease and cancer

D. people must take vitamins on a regular basis

2.What can we conclude from Task Force's findings?

A. Scientists want to control cardiovascular disease.

B. In some aspects, taking vitamins is not useful.

C. Producers cannot produce medical－use vitamins.

D. Vitamins must be useful to prevent cancer and heart disease.

3.Who can take vitamins regularly according to the advice of the Task Force?

A. A 60－year－old healthy worker.

B. A 15－year－old boy with short－sightedness.

C. A 34－year－old pregnant lady.

D. A 40－year－old man who never eats vegetables or fruits.

4.What's the best title for the text?

A. An Inside Look at Vitamins

B. Task Force: Ending to Vitamins

C. Vitamins: To Live or to Kill

D. Taking Vitamins to Prevent Diseases May Fail
