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.
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.

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.

Which of the following shows the structure of the passage?

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

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.
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.

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

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

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.

She may have lacked a home, but now this teen has top honors.
A 17-year-old student who spent much of high school living around homeless shelters — and sometimes sleeping in her car — today graduated and spoke on behalf of her class at Charles Drew High School in Clayton County, Ga., just outside of Atlanta.
Chelsea Fearce held a 4.466 GPA and scored 1900 on her SATs despite having to use her cellphone to study after the shelter lights were turned off at night.
“I know I have been made stronger. I was homeless. My family slept on cushions on the floor and we were lucky if we got more than one full meal a day. Getting a shower, food and clean clothes was an everyday struggle,” Fearce said in a speech she gave at her graduation ceremony. Fearce overcame her day-to-day struggles by focusing on a better day. “I just told myself to keep working, because the future will not be like this anymore,” she told WSBTV.
Fearce, one of five children, grow up in a family that sometimes had an apartment to live in, but at other times had to live in homeless shelters or even out of their car, if they had one. “You’re worried about your home life and then worried at school. Worry about being a little hungry sometimes and go hungry sometimes. You just have to deal with it. You eat what you can, when you can.”
To our surprise, Fearce overcame the difficulties and even tested high enough to be admitted into college half way through her high school career. She starts college next year at Spelman College as a junior where she is planning to study biology, pre-med (医学预科). “Don’t give up. Do what you have to do right now so that you can have the future that you want,” Fearce said.
How did Fearce go on with her study without access to lights?

A．By the car light.

B．By her cellphone.

C．By lights out of shelters.

D．By moonlight.

When Fearce starts college at Spelman College, she will _____..

A．have graduated earlier from high school than normal

B．be a 17-year-old student from a poor family

C．have a home without sleeping in her car or shelters

D．have raised enough money to go to college

What lesson can we learn from Fearce’s experience?

A．Knowledge can change your fate.

B．Don’t give up, and tomorrow will be better.

C．Whatever is worth doing is worth doing well.

D．He that will not work shall not eat.

In the mid-1950s, I was a somewhat bored early-adolescent male student who believed that doing any more than necessary was wasted effort. One day, this approach threw me into embarrassment
In Mrs. Totten’s eighth-grade math class at Central Avenue School in Anderson, Indiana, we were learning to add and subtract decimals (小数).
Our teacher typically assigned daily homework, which would be recited in class the following day. On most days, our grades were based on our oral answer to homework questions.
Mrs. Totten usually walked up and down the rows of desks requesting answers from student after student in the order the questions had appeared on our homework sheets. She would start either at the front or the back of the classroom and work toward the other end.
Since I was seated near the middle of about 35 students, it was easy to figure out which questions I might have to answer. This particular time, I had completed my usual two or three problems according to my calculations.
What I failed to expect was that several students were absent, which threw off my estimate. As Mrs. Totten made her way from the beginning of the class，I desperately tried to determine which math problem I would get. I tried to work it out before she got to me, but I had brain freeze and couldn’t function.
When Mrs. Totten reached my desk，she asked what answer I’d got for problem No. 14. “I…I didn’t get anything,” I answered，and my face felt warm.
“Correct,” she said.
It turned out that the correct answer was zero.
What did I learn that day? First, always do all your homework. Second, in real life it isn’t always what you say but how you say it that matters. Third，I would never make it as a mathematician.
If I could choose one school day that taught me the most, it would be that one.

A．It is wise to value one’s time.

B．It is important to make an effort

C．It is right to stick to one’s belief.

D．It is enough to do the necessary.

People aren’t walking any more---if they can figure out a way to avoid it.
I felt superior about this matter until the other day I took my car to mail a small parcel. The journey is a matter of 281 steps. But I used the car. And I wasn’t in any hurry, either, I had merely become one more victim of a national sickness: motorosis.
It is an illness to which I had thought myself immune(免疫的), for I was bred in the tradition of going to places on my own two legs. At that time, we regarded 25 miles as good day’s walk and the ability to cover such a distance in ten hours as sign of strength and skill. It did not occur to us that walking was a hardship. And the effect was lasting. When I was 45 years old I raced –and beat—a teenage football player the 168 steps up the Stature of Liberty.
Such enterprises today are regarded by many middle-aged persons as bad for the heart. But a well-known British physician, Sir Adolphe Abrhams, pointed out recently that hearts and bodies need proper exercises. A person who avoids exercise is more likely to have illnesses than one who exercises regularly. And walking is an ideal form of exercise--- the most familiar and natural of all.
It was Henry Thoreau who showed mankind the richness of going on foot. The man walking can learn the trees, flower, insects, birds and animals, the significance of seasons, the very feel of himself as a living creature in a living world, He cannot learn in a car.
The car is a convenient means of transport, but we have made it our way of life. Many people don’t dare to approach Nature any more; to them the world they were born to enjoy is all threat. To them security is a steel river thundering on a concrete road. And much of their thinking takes place while waiting for the traffic light to turn green.
I say that the green of forests is the mind’s best light. And none but the man on foot can evaluate what is basic and everlasting.
