【題目】閱讀下面短文,根據(jù)其內(nèi)容寫一篇60詞左右的內(nèi)容概要。

We live in a technological society where most goods are mass-produced by unskilled labor. Because of this, most people think that craft (手藝) no longer exists. One of the ways these people wrongly support their view is by pointing to 100-year-old homes which are still solid, and arguing that it is the craftsmanship that is responsible for their durability (持久性). “Homes in those days were well-built,” they say. There is no doubt that these homes were well-built, but what these people have done is mix up the quality of material used in the house with the quality of the craftsmanship.

Homes today could be built to last just as long as those old homes if people were willing or able to pay the price. For example, more people can no longer afford solid oak stairways, although they were once fairly common in older homes. Nor can they afford the high labor cost of employing a carpenter to build the stairway. Yet if someone can pay the high cost, there are still plenty of carpenters around able to make those stairways. And not only would these carpenters know how to build them, they would probably do a better job than carpenters of old.

One thing the modern carpenter has which enables him to do a better job is much more advanced tools. Such tools as laser beams and power planes help them lay out a house better and make more precision cuts (精確切割) on the wood. Also, it is not uncommon any more to find carpenters with college degrees and carpenters with a solid knowledge of mathematics, which would enable them to deal with more difficult house designs.

The problem of modern quality, then, really boils down to the problem of material, for the modern carpenter is just as able to produce craftsmanship as the carpenter of fifty years ago, but only if given proper material.

【題目】 Scott Ward didn't have any risk factors that he knew of for cancer so he ignored the lump on his neck until he couldn't ignore it anymore. Dr. Donald Doll, the doctor who treated Ward for his cancer, said, “We’re seeing more and more younger and healthier patients. They're not smokers or drinkers. It's HPV-related.” “Normally, you think of HPV (乳頭瘤病毒), you think of women,” Doll added, “while it's a misconception that only women have to be concerned with cancers caused by this virus.”

Luckily, there's a vaccine (疫苗) that's been around for more than a decade that can protect against the HPV virus. If all boys and girls received it, no one would get HPV-related cancers. The HPV vaccine is best when given to children between 9 and 12 years old, before they are sexually active. But teenagers and young adults can still benefit from the vaccine.

Not everyone who gets the HPV virus develops cancer. But it is a risk factor. The agency says about 14 million people in the U.S. alone become infected with HPV each year. Yet, about half of all U.S. adolescents have not been fully vaccinated against HPV, which requires a series of three shots. The CDC says the side effects are generally short term and not serious. They can include dizziness, headache, fever, pain and etc.

Ward’s recovery was difficult. But he’s now cancer-free. Ward wishes the HPV vaccine existed when he was a teen. He says if he had kids, he would get them vaccinated. “HPV-related cancers are cancers no one needs to get.” Ward said.

1Who should be worried about HPV-related cancers?

A.Only women.B.Everyone.

C.Younger people.D.Smokers and drinkers.

2Which of the following statements is TRUE according to the passage?

A.The HPV vaccine is best when given to teenagers and young adults.

B.About 50% of all adults in America have not been fully vaccinated against HPV.

C.One gets cancer if he or she gets the HPV virus.

D.HPV vaccines have some side effects including dizziness, headache, and etc.

3Why did Ward say HPV-related cancers were cancers no one needed to get in the last paragraph?

A.It is easy to recover from HPV-related cancers.

B.HPV-related cancers are not that common.

C.HPV-related cancers can be prevented by vaccination.

D.HPV vaccine existed when he was a teen.

【題目】 A new study has found no evidence that sunscreen, commonly used to reduce the risk of skin caner, actually increases the risk.

Researchers from the University of Yale based their findings on a review of 18 earlier studies that looked at the association between sunscreen use and melanomas(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(發(fā)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.

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

A.evidencesB.factsC.faultsD.failures

2People with fair skin and freckles ________.

A.seldom use sunscreenB.are more in danger of skin cancerC.can be free from the harm of the sun D.often expose themselves to the sun

3We 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

4Which 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
