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.

1.The underlined word “flaws” in the 2nd paragraph most probably means 　　　　 .

A. evidences        B. facts        C. faults        　　 D. failures

2.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

3.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

4.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

A new study has found evidence of aggressive (攻击性的) behavior in children who drink four or more servings of soft drinks every day. Information for the study came from the mothers of 3,000 5-year-olds. Researchers asked the women to keep a record of how many servings of soft drinks their children drank over a two-month period. They were also asked to complete a checklist of their children’s behavior.

The researchers have found that 43 percent of the children drink at least one daily serving of soda, and 4 percent of the youngsters have even four or more sodas to drink every day.

Shakira Suglia, a famous expert, says they’ve found that children who drink the most soda are more than twice as likely as those who drink no soda to show signs of aggression.

“For the children who consume four or more soft drinks per day, we see more withdrawn behaviors, which make them hard to get along well with others.”

The aggressive behaviors include destroying possessions belonging to others, taking part in fights and physically attacking people.

The researchers have determined the link after considering factors like the child’s age and sex. They have also considered other possible influence, such as whether the boys and girls are eating sweets or giving fruit drinks on a normal day. In addition, the researchers have examined parenting styles and other social conditions that may be taking place in the home.

Researches are trying to find why young children who drink a lot of soda have behavior problems. An ingredient often found in soft drinks is caffeine, which helps to make people feel energetic. Doctor Suglia suggests that caffeine could cause the 5-year-olds to be more aggressive. Earlier studies of adults have found the highest sugar levels in those who carry weapons (武器) and show signs of negative social behavior.

1.What section of a newspaper is the passage probably taken from?

A. Scientific Technology    B. Science Fictions　　

C. Social News    D. Health Report

2.The underlined word “withdrawn” in paragraph 4 can probably be replaced by the word ______.

A. backward            B. unsocial            C. generous        D. friendly

3.Researchers studied the following aspects of the children except ______.

A. age                    B. sex                C. games            D. parents

4.According to the research, which of the following is right?

A. Mothers were asked to keep a record of how many servings of soft drinks their children drank over a three-month period.

B. 4 percent of the youngsters have even four or fewer sodas to drink every day.

C. Children who drink no soda show fewer aggressive behaviors.

D. Children with the highest sugar levels tend to carry weapons and show signs of negative social behavior.

5.After a further study on ingredients in soda, Shakira Suglia implies that the direct cause of the aggressive behaviors may be ______.

A. soft drinks        　 B. attention problems    　　　　

C. caffeine         D. social conditions
