Can people change their skin colour without suffering like pop king Michael Jackson? Perhaps yes. Scientists have found the gene that determines skin colour.

The gene comes in two versions, one of which is found in 99 per cent of Europeans. The other is found in 93 to 100 per cent of Africans, researchers at Pennsylvania State University report in the latest issue of Science.

Scientists have changed the colour of a dark-striped zebrafish to uniform gold by inserting a version of the pigment(色素) gene into a young fish. As with humans, zebrafish skin colour is determined by pigment cells, which contain melanosomes(黑色素). The number, size and darkness of melanosomes per pigment cell determines skin colour.

It appears that, like the golden zebrafish, light-skinned Europeans also have a mutation(变异) in the gene for melanosome production. This results in less pigmented skin.

However, Keith Cheng, leader of the research team, points out that the mutation is different in human and zebrafish genes.

Humans acquired dark skin in Africa about 1.5 million years ago to protect bodies from ultra-violet rays(紫外线) of the sun, which can cause skin cancer.

But when modern humans leave Africa to live in northern latitudes, they need more sunlight on their skin to produce vitamin D. So the related gene changes, according to Cheng.

Asians have the same version of the gene as Africans, so they probably acquired their light skin through the action of some other gene that affects skin colour, said Cheng.

The new discovery could lead to medical treatments for skin cancer. It also could lead to research into ways to change skin colour without damaging it like chemical treatment did on Michael Jackson.

24. What is the main idea of the passage?

A. People can’t change their skin colour without any pain.

B. The new discovery helped find ways to change skin colour safely.

C. Pop king Michael Jackson often changed his skin colour as he liked.

D. Scientists have found out that people’s skin colour is determined by the gene.

25. It can be inferred from the passage that ________.

A. nowadays changing the skin colour with the chemical treatment has bad effect

B. Europeans and Africans have the same genes

C. the new discovery could help to find medical treatments for skin cancer

D. there are two kinds of skin genes

26. Scientists have done an experiment on a dark-striped zebra fish in order to ________.

A. find the different genes of humans

B. prove the humans’ skin colour is determined by the pigment gene

C. find out the reason why the Africans’ skin colour is dark

D. find out the ways of changing people’s skin colour

27. Which of the following statements is TRUE?

A. Michael Jackson died of skin damage caused by chemical treatment.

B. American blacks produce more vitamin D with their skin than others.

C. The gene determining skin colour exists widely in whites, blacks and Asians.

D. The melanosomes in the skin of blacks usually cause skin cancer more often.

Drinking alcohol is a socially acceptable behavior in many parts of the world. Some medical experts say light drinking may even be good for your health, especially for the heart. But they say such health benefits should be compared to the many health risks connected with alcohol use.

Some research suggests that having one to two drinks of alcohol a day may offer some health benefits. Several large studies have shown that this type of moderate(适量的) drinking may lower the risk of heart disease and other diseases.

A study last year suggested that drinking small amounts of red wine may help lower the risk of breast cancer in women. Researchers at Medical Center in California studied 36 women. Each woman drank a glass of red or white wine every day for almost a month. Researchers collected blood samples from the women two times a month to measure their hormone(激素) levels. The next month the women who drank red wine were told to drink white wine instead. The white wine drinkers were told to drink red wine. The researchers found that the women who drank red wine had lower levels of the female hormone than the white wine drinkers. They said red grapes have chemicals that may help to lower the risk of breast cancer.

However, recent studies suggested that even small amounts of alcohol may generally increase the risk of breast cancer in women. They found that women who drink four small glasses of wine a week increase their risk of breast cancer by 15 percent.

Many studies have examined the harmful effects of alcohol use on the body. Alicia Ann Kowalchuk serves as medical director, saying “Healthy use for adults --- that's men under age 65 --- is no more than 4 drinks in a day and no more than 14 drinks in a week. And for women of all ages, it's no more than 7 drinks in a week and no more than 2 drinks in a day.” She says too much alcohol use has been linked to liver diseases, and many other cancers.

28. How did the researchers carry out their study?

A. By following an example.

B. By listing facts.

C. By collecting information worldwide.

D. By comparing tested objects.

29. Which of the following is the most beneficial to women with breast cancer?

A. A glass of white wine per day.

B. A glass of red wine per day.

C. Small amounts of alcohol per day.

D. Four small glasses of wine per day.

30. Which of the following shows the structure of the passage?

31. What is the best title of this passage?

A. Drinking alcohol is popular in many parts of the world

B. Alcohol drinking can be both good and bad for you

C. Drinking alcohol a day may give your health some benefits.

D. Alcohol drinking may do harm to your health

That morning, I stepped into the classroom, ready to share my knowledge and experience with seventy-five students who would be my English Literature class. Having taught in 41 for seventeen years, I had no 42 about my ability to hold their attention and to 43 on them my admiration for the literature of my mother tongue.

I was shocked when the monitor shouted, " 44 !" The entire class rose as I entered the room, and I was somewhat 45 about how to get them to sit down again, but once that awkwardness was over, I quickly 46  my calmness and began what I thought was a fact-packed lecture, sure to gain their respect—perhaps 47 their admiration. I went back to my office with the rosy glow which came from a sense of achievement.

My students 48 diaries. However, as I read them, the rosy glow was gradually 49 by a strong sense of sadness. The first diary said, "Our literature teacher didn’t teach us anything today. 50 her next lecture will be better." Greatly surprised, I read diary after diary, each expressing a 51 theme. "Didn’t I teach them anything? I described the entire philosophical framework of Western thought and laid the historical 52 for all the works we’ll study in class," I complained." How 53 they say I didn’t teach them anything?"

It was a long term, and it 54 became clear that my ideas about education were not the same as 55 of my students. I thought a teacher’s job was to raise 56 questions and provide enough background so that students could 57 their own conclusions. My students thought a teacher’s job was to provide 58 information as directly and clearly as possible. What a difference!
