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 zebra fish to uniform gold by inserting a version of the pigment (色素) gene into a young fish. As with humans, zebra fish skin colour is determined by pigment cells, which contain melanosomes (黑色素体). The number, size and darkness of melanosomes per pigment cell determines skin colour.
It appears that, like the golden zebra fish, light-skinned Europeans also have a mutation (突变)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 zebra fish genes.
Humans acquired dark skin in Africa about 1.5 million years ago to protect bodies from ultra-violet rays 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 colours, 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 done on Michael Jackson.According to the passage, scientists have found .
| A．people living in northern latitudes need more sunlight |
| B．the reason why people change their skin colour |
| C．the reason why people get skin cancer |
| D．the gene that determines skin colour |
We can infer from the passage that .
| A．people like to change their skin colour |
| B．a mutation in the gene for melanosome production is different in human and zebra fish gene |
| C．people will be able to change their skin colour without chemical treatment in the future |
| D．skin cancer can be cured now |
Which of the following is NOT mentioned according to the passage?
| A．The version of the pigment gene of Asians and that of Africans are the same. |
| B．Scientists have succeeded in turning the colour of a dark-striped zebra fish into uniform gold. |
| C．Dark skin can protect bodies from utral-violet rays of the sun. |
| D．People like pop king Michael Jackson. |

Michelle Obama has just started a campaign against childhood obesity（肥胖）with the admission that she put her girls Malia and Sasha on a diet because they were getting fat．Clearly，childhood obesity must be solved urgently．But is it a good idea for mothers to put their daughters on diets?
Studies
show that the more children diet，the more likely they are to become obese as adults．
Research also shows that gifts are highly influenced by their mothers when it comes to eating habits and body image．
This was the case for Carly，40，who blames her mother for her lifelong struggle with weight．“My mother was on a diet the whole time I was growing up，”she says．“And she put me on my first diet when I was 10．I lost puppy fat，gained her approval and never ate normally again.”
America’s First Lady clearly has a vital healthy eating message to convey．But could this be damaging for Malia and Sasha? Could they develop eating disorders because of it?
“It’s wrong just to blame mothers for their daughters’eating disorders，”says Susan Ringwood，chief executive of the eating disorders charity，Beat．“There is a genetic（基因的）component to eating disorders．However，“We do know that parents have a very strong influence over a child’s eating．It's important to realize that you are your daughter’s role model．Girls idolize their mothers．”says Ringwood．
“No food should ever be‘good’ or‘bad’，” Ringwood says．Instead，“You have to make it clear that food is a sociable，healthy and fun part of life，not something to be feared．”
“Talk to her about body image，”Ringwood says．“Talk about how curves are an important and exciting part of being a woman．Show her that anorexic（厌食的）fashion models are not sexy，but ill．The pressure on girls today is immense，”she says．“But don’t forget that you are the authoritative voice，too．”

Amiya Olden could have been a poster child for a reading crisis that affects nearly 2 million Michigan residents older than 1 6：They read below a sixth-grade level，which makes it difficult to find jobs and to improve their lives．Among them，Amiya is one．
Amiya Olden remembers well the day she graduated from Denby High school．She handed her diploma to her mother，who read it to her．“Then when someone asked me to read it，I could remember the things she read，and I knew what I had to say，”recalled Amiya Olden．“When we would go out to restaurants with my aunts，and that is when I really would get upset．1 would see words on the menu but I couldn’t read! ”
But don‘t feel sorry for her. She changed her life by reaching a point where she’d read enough．Two summers ago，she took charge of her life when she walked into Pro Literacy Detroit to improve her reading．Nineteen months ago，she was reading at a second-grade level；now at a fifth-grade level．
Olden now splits her days between her classes at Pro Literacy and the library，where she checks out books and reads them．She says she hopes her improved reading skills will help her find a good job．
And she has advice for others，who have trouble reading．
“Don’t give up on it，”she said．“Even though it can be challenging and you might get frustrated sometimes，practice does help．If you really want to be able to go somewhere，go out to a restaurant and you have to read signs and things like that，you want to know what you want to eat and where you want to go．．．If you want to succeed in life and grow，you have to read．More important，you have to feel confident that you can．”

I love charity(慈善) shops and so do lots of other people in Britain because you find quite a few of them on every high street. The charity shop is a British institution, selling everything from clothes to electric goods, all at very good prices. You can get things you won't find in the shops anymore. The thing I like best about them is that your money is going to a good cause and not into the pockets of profit-driven companies, and you are not damaging the planet, but finding a new home for unwanted goods.
The first charity shop was opened in 1947 by Oxfam. The famous charity's appeal to aid postwar Greece had been so successful it had been flooded with donations(捐赠物). They decided to set up a shop to sell some of these donations to raise money for that appeal. Now there are over 7,000 charity shops in the UK. My 
favourite charity shop in my hometown is the Red Cross shop, where I always find children's books, all 10 or 20 pence each.
Most of the people working in the charity shops are volunteers, although there is often a manager who
gets paid. Over 90% of the goods in the charity shops are donated by the public. Every morning you
see bags of unwanted items outside the front of shops, although they don't encourage this, rather ask people to bring things in when the shop is open.
The shops have very low running costs: all profits go to charity work. Charity shops raise more than ￡110 million a year, funding（资助）medical research, overseas aid, supporting sick and poor children, homeless and disabled people, and much more. What better place to spend your money? You get something special for a very good price and a good moral sense. You provide funds to a good cause and tread lightly on the environment.The author loves the charity shop mainly because of _______.
| A．its convenient location |
| B．its great variety of goods |
| C．its spirit of goodwill |
| D．its nice shopping environment |

| B．The staff are usually well paid. |
