Researchers have found more evidence that suggests a relationship between races (种族) and rates (率) of lung cancer among smokers. A new study shows that black people and Native Hawaiians are more likely to develop lung cancer from smoking. It compared their risk to whites, Japanese-Americans and Latinos.

Researchers at the University of Southern California and the University of Hawaii did the new study. The New England Journal of Medicine published the findings. The eight-year research studied more than 180,000 people. They included present and former smokers and people who never smoked. Almost 2.000 people in the study developed lung cancer.

Researchers say genetics (遗传学) might help explain the racial and ethnic（种族的） differences. There could be differences in how people's bodies react to smoke. But environmental influences, including the way people smoke, could also make a difference.

African-Americans and Latinos in the study are reported smoking the fewest cigarettes per day. Whites are the heaviest smokers. But the scientists point out that blacks have been reported to breathe cigarette smoke more deeply than white smokers. This could fill their lungs with more of the chemicals in tobacco that cause cancer.

Scientists know that some diseases effect different groups differently. And some drug companies have begun to develop racially targeted (针对) medicines. Last June, the United States Food and Drug Administration approved a drug designed to treat heart failure in black patients. The name is BiDil. The agency called it "a step toward the promise of personalized medicine."

A．the larger amount of smoking than white people

2.People in the new study are made up of         .

A．explain different races react to some diseases differently

B．tell the readers that racial differences exist in smokers

C．show a big step people have taken in the medicine area

D．support the idea that it is easy for blacks to have cancers

4.Which of the following statements is TRUE according to the author?

A．The way of smoking may increase the risk of lung cancer.

B．Race has nothing to do with the risk of having a lung cancer.

C．The research was started by the New England Journal of Medicine.

Recently, South Korean star PSY’s ‘Gangnam style” video has been popular on the Internet. It has become most people’s favorite music.
In fact, the song has set the Guinness World Record for the most popular video in the history of the Internet. More than two million people have said “like” since the song was on the Internet on July 15.

The song has come to first place in the music charts(排行榜) in 31 countries, including the United States, the United Kingdom, and Canada.
“I just sang for my South Korean fans. I have never expected it to be popular in other countries,” PSY told the reporters on a concert. The song was so popular that a few of South Korean’s politicians showed PSY’s moves to attract supporters.
“The song came out in mid-July. It sings about the rich life of South Korea —especially Gangnam in Soeoul, where a lot of rich people live.
Millions of people have watched the video. Many stars, such as Katy Perry, Robbie Williams and Nelly Furtado said that they love the song. These stars performed part of the song at a recent concert.
Riding high on the success of “Gangnam Style”, PSY was signed by Scooter Braun to Braun’s Schoolboy Records, a label distributed by Universal Republic.
PSY has written many hit songs of varying styles for different singers. Prior to “Gangnam Style” his most famous composition perhaps was Lee Seung Gi’s debut(首次亮相) song “Because You Are My Woman”.
【小题1】What makes PSY’s “Gangnam Style” the famous music of millions of people?

Shopping is not as simple as you may think! There are all sorts of tricks at play each time we reach out for that particular brand (商标) of product on the shelf.

Colouring, for example, varies according to what the producers are trying to sell. Health foods are packaged (包装) in greens, yellows or browns because we think of these as healthy colours. Ice cream packets are often blue and expensive goods, like chocolates, are gold or silver.

When some kind of pain killer was brought out recently, researchers found that the colours turned the customers off because they made the product look weak and ineffective. Eventually, it came on the market in a dark blue and white package—blue because we think of it as safe, and white as calm.

The size of a product can attract a shopper. But quite often a bottle doesn’t contain as much as it appears to.

It is believed that the better-known companies spend, on average, 70 per cent of the total cost of the product itself on packaging!

The most successful producers know that it’s not enough to have a good product. The founder of Pears soap, who for 25 years has used pretty little girls to promote(推销)  their goods, came to the conclusion: “Any fool can make soap, but it takes a genius (天才) to sell it.”

1.Which of the following may trick a shopper into buying a product according to the text?

2.The underlined part “the colours turned the customers off”(in Para. 3 ) means that the colours _____.

3.Which of the following is the key to the success in product sales?

4.Which of the following would be the best title for this text?

　More surprising, perhaps, than the current difficulties of traditional marriage is the fact that marriage itself is alive and thriving（旺盛的）. As Skolnich notes, Americans are a marrying people: relative to Europeans, more of us marry and we marry at a younger age. Moreover, after a decline（衰退）in the early 1970s, the rate of marriage in the United States is now increasing. Even the divorce（离婚）rate needs to be taken in this pro- marriage context: some 80 percent of divorced individuals remarry. Thus, marriage remains by far the preferred way of life for the vast majority of the people in our society.

　　What has changed more than marriage is the nuclear family. Twenty- five years ago, the typical American family consisted of the husband, the wife, and two or three children. Now, there are many marriages in which couples have decided not to have any children, and there are many marriages where at least some of the children are from the wife’s previous marriage, or the husband’s, or both. Sometimes these children spend all of their time with one parent from the former marriage; sometimes they are shared between the two former spouses （配偶）．

　　Thus, one can find every type of tamely arrangement. There are marriages without children; marriages with children from only the present marriages; marriages with “full - time” children from both the present and former marriages; marriages with“full- time”children from the present marriage and“ part- time”children from former marriages. There are stepfathers, stepmothers, half- brothers and half - sisters. It is not all that unusual for a child to have four parents and eight grandparents! These are enormous changes from the traditional nuclear family. But even so, even in the midst of all this, there remains one constant: most Americans spend most of their adult lives married.

　　A. Americans are more traditional than Europeans
