A new study has found no evidence that sunscreen, commonly used to reduce the risk of skin cancer, actually increases the risk.
Researchers from the University of Iowa based their findings on a review of 18 earlier studies that looked at the association between sunscreen use and melanoma(黑素瘤). They said that they found flaws in studies that had reported associations between sunscreen use and higher risk of melanoma.
Most health experts believe that by protecting the skin from the harmful effects of the sun, sunscreen helps prevent skin cancer, which is increasing in incidence(发生率)faster than any other cancer in the United States.
But questions have been raised about sunscreen and whether it may have the opposite effect, perhaps by allowing people to remain exposed to the sun longer without burning.
The researchers said that among the problems with some earlier studies is that they often failed to take into account that those people most at risk for skin cancer—people with fair skin and freckles(雀斑), for example—are more likely to use sunscreen. As a result, it may appear that sunscreen users get cancer more often.
The studies, which generally relied on volunteers to recall their sunscreen use, were also unable to prove how well the products had been applied, said the new study.The underlined word “flaws” in the 2nd paragraph most probably means .
A.evidences | B.facts | C.faults | D.failures |
People with fair skin and freckles .
A.seldom use sunscreen |
B.are more in danger of skin cancer |
C.can be free from the harm of the sun |
D.often expose themselves to the sun |
We can learn from the passage that .
A.sunscreen users get skin cancer more often |
B.the volunteers have proved the effect of sunscreen |
C.the new study was based on the experiences of volunteers |
D.the number of skin cancer patients is increasing in America |
Which of the following can be the best title for this passage?
A.Sunscreen to Prevent Skin Cancer |
B.Sunscreen to Increase Skin Cancer |
C.Skin Cancer Caused by Sunscreen |
D.Skin Cancer Caused by Freckles |

What exactly is a lie? Is it anything we say which we know is untrue? Or is it something more than that? For example, suppose a friend wants to borrow some money from you. You say, "I wish I could help you but I'm short of money myself." In fact you are not short of money but your friend is in the habit of not paying his debts and you don't want to hurt his feelings by reminding him of this. Is this really a lie?
Professor Gerald Gullion of the University of Southern California has made a scientific study of lying. According to him, women are better liars than men, particularly when telling a "white lie", such as a woman at a party telling another woman that she likes her dress when she really thinks it looks awful. However, this is only one side of the story. Other researchers say that men are more likely to tell more serious lies, such as making a promise which they have no intention of fulfilling. This is the kind of lie politicians and businessmen are supposed to be particularly skilled at: the lie from which the liars hopes to profit or gain in some way.
Research has also been done into the changes of people’s behavior in a number of small, clearly unimportant ways when they lie. It has been found that if they are sitting down at the time, they tend to move about in their chairs more than usual. To the trained observer they are saying “I wish I were somewhere else now”. They also tend to touch certain parts of the face more often, in particular the nose. One explanation of this may be that lying causes a slight increase in blood pressure. The nose is very sensitive to such changes and the increased pressure makes it itch (痒).
Another gesture which gives away is what the writer Desmond Morris in his book Man Watching calls “the mouth cover”. He says there are several typical forms of this, such as covering part of the mouth with fingers, touching the upper-lip or putting a finger of the hand at one side of the mouth. Such a gesture can be understood, as an unconscious attempt on the part of the liar to stop himself or herself from lying.
Of course, such gestures as rubbing the nose or covering the mouth, or moving about in a chair cannot be taken as proof that the speaker is lying. They simply tend to occur more frequently in this situation. It is not one gesture alone that gives the liar away but a whole number of things, and in particular the context in which the lie is told.

A
I was walking along Orchard Road when I realized a tall young man wearing a jacket and tie was following me. I noticed him because not many people wear a jacket and tie in the middle of a hot summer day, and I had already seen this man four times that afternoon.
To make sure he was following me, I walked on quickly, turned right into a shopping center and then stopped to look in a shop window. Soon the man appeared and stopped at another shop window. I walked on and stopped several times. When I stopped, he stopped too.
I began to be rather worried and decided to try to lose this strange man. When I saw a taxi coming, I jumped into it. As I was telling the taxi driver where to go, I found the man get into another taxi, which then followed mine. As the two taxies slowly made their way along Orchard Road, I looked back at the taxi behind, and saw that the stranger was looking out at me. At MRT station, I told the taxi driver to stop and I got out. As I was paying my fare, I saw the man was getting out of his taxi.
By now I got angry, so I turned and walked straight to him. I asked him why he was following me. At first he said he was not following me at all, but when I threatened(威胁) to call the police, he admitted he was. He then told me that he was a news reporter and that he was writing an article on how elderly people in Singapore spend their time. He said he was observing me to gather materials for his article.

“In only six days I lost seven pounds of weight.”
“Two full inches in the first three days!”
These are the kinds of statements used in magazine, newspaper, radio and television ads, promising new shapes and new looks to those who buy the medicine or the device. The promoters(推销员) of products say they can shape the legs, slim the face, smooth wrinkles, or in some other way to beauty or desirability.
Often such products are nothing more than money-making things for their promoter. The results they produce are questionable, and some are dangerous to health.
To understand how these products can be legally(合法地) promoted to the public, it is necessary to understand something of the laws covering their regulation. If the product is a drug, FDA(Food Drug Administration)can require proof (证明) under the Food, Drug, and Cosmetic Act that it is safe and effective before it is put on the market. But if the product is a device, FDA has no authority(="right)" to require premarketing proof of safety or effectiveness. If a product already on the market is a danger to health, FDA can request the producer or distributor to remove it from the market voluntarily(主动地), or it can take legal action, including seizure (查封) of the product.
One notable case a few years ago involved an electrical device called the Relaxacisor, which had been sold for reducing the waistline. The Relaxacisor produced electrical shocks to the body through contact pads. FDA took legal action against the distributor to stop the sale of the device on the grounds that it was dangerous to health and life.
Obviously, most of the devices on the market have never been the subject of court proceedings (法律诉讼), and new devices appear continually. Before buying, it is up to the consumer(消费者) to judge the safety or effectiveness of such items.
72. It can be inferred that ads mentioned in the text are _________.
A. objective B. costly(昂贵的) C. unreliable D. illegal
73. FDA can ask for the proof of safety and effectiveness of a product _________.
A. if it is a drug B. if it is a device
C. if its consumers make complaints D. if its distributors challenge FDA’s authority
74. The Relaxacisor is mentioned as _________.
A. a product which was designed to produce electricity
B. a product whose distributor was involved in a legal case
C. a successful advertisement of a beauty product
D. an example of a quality beauty product
75. The author intends to _________.
A. make consumers aware of(意识到) the promoters’ false promises
B. show the weakness of the law on product safety
C. give advice on how to keep young and beautiful
D. introduce the organization of FDA
