    A new study has found no evidence that sunscreen, commonly used to reduce the risk of skin cancer, actually increase 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 has been raised about sunscreen and whether it may has 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.

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

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

73. 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

74. 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

75. Which of the following can be the 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

When building houses, people used to think about not only the climate of the areas but also the building materials and the fashions for their houses. However, since electricity became more and more expensive, people began to pay much more attention to the energy they could get for their houses and the new ways they could find to protect their houses from both cold and heat.
Now, houses of an old yet new type have been widely built. In some parts of the world, people share their houses with their livestock. During cold weather, they gather their cows, goats, or other animals and keep them on the first floor of their houses. The reasons are that the animals can be protected from the cold and that they can help to heat the houses as well. The body heat given off by the animals rises to the second floor of the houses, where people live. By sharing their houses with their livestock, people gain a source of heat.
People who live in or near cities do not usually keep livestock. However, home builders use the fact that heat rises. This natural law can be used in building houses in these areas. Instead of keeping livestock on the first floor, builders fill it with large rocks. As they are open to the sun’s rays during cold weather, these rocks take in heat. They also give off the heat, and, of course, the warm air rises into the living areas of the houses. So these houses are energy-saving.
House building becomes a great challenge to building designers and energy engineers. They try to meet this challenge by learning from old traditions and by using modern technology. And someday in the future, people will be able to live in more energy-saving houses.
【小题1】What did people begin to consider as electricity was no longer cheap?

A.The climate of their areas
B.The building materials for their houses
C.The fashions for their houses
D.The energy for their houses
【小题2】People in some areas gain a source of heat by _________.
A.keeping their livestock downstairs
B.protecting their livestock from the cold
C.sharing their houses only with their cows
D.living on the second floor with their livestock
【小题3】The underlined words “natural law” in the third paragraph refer to the fact that ________.
A.heat raises the temperature in the houses
B.heat goes in the upward direction
C.heat goes up if temperature is raised
D.heat increases the temperature of rocks
【小题4】From the passage, we can conclude that _______ .
A.people will no longer consider building materials in the future
B.almost all people will move into the houses heated by large rocks
C.energy-saving buildings will become more popular in the future
D.energy engineers will devote themselves only to modern technology
【小题5】What is the main idea of the passage?
A.Energy-saving house building
B.House building is a great challenge
C.How to live in energy-saving houses
D.Energy-saving houses’ bright future
