British and Canadian experts say drugs could attack the parasite（寄生虫） causing the illness．They say the drug could be ready for human medical test in about 18 months．
The disease, spread by the bite of a fly, is caused by a parasite attacking the central nervous system．It has similar symptoms（症状） to malaria（疟疾）, making it difficult to diagnose．Left untreated, it moves to the brain, resulting in mental confusion and final death
The "breakthrough" came at the University of Dundee in Scotland, where scientists were offered money to research diseases ignored by major drugs companies．
Professor Paul Wyatt, director of the programme, said: "This is one of the most significant findings made in recent years in terms of drug discovery and development for ignored diseases."
He said the research, published in the journal Nature, represented "significant progress" in the development of a full blown drug against the disease．
The World Health Organization said there are between 50,000 and 70,000 cases of the disease a year, with a further 60 million people at risk of infection．
The research in Dundee was backed by partners at the University of York in England and the Structural Genomics Consortium in Toronto, Canada．The two drugs currently available to treat sleeping sickness both have problems．One is with side effects that kill one in 20 patients and the other is costly, only partially effective and requires long-time hospital treatment, the scientists said．
小题1:The word backedin the last paragraph probably means_____.
| A．conducted | B．supported | C．believed | D．managed |
| A．about 60000 people died of the disease each year |

Researchers from the University of Iowa based their findings on a review of 18 earlier studies that looked at the association between sunscreen use and melanoma (黑素瘤)．They said that they found faults 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 (发生率) faster than any other cancer in the United States.
But questions has been raised about sunscreen and whether it may has 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.
小题1:People with fair skin and freckles .
| A．seldom use sunscreen |
| B．are more in danger of skin cancer |
| C．can be free from the harm of the sun |
| D．often expose themselves to the sun |
| 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 |
| A．Sunscreen to Prevent Skin Cancer |
| B．Sunscreen to Increase Skin Cancer |
| C．Skin Cancer Caused by Sunscreen |
| D．Skin Cancer Caused by Freckles |
“Grown-ups with music training in their childhood can have better memory for words,” said Dr Agnes Chan of the Chinese University of Hong Kong, who did the research. “They can remember things that you tell them better than those who did not have music training when they were young.”
It seems that one can remember spoken words because his brain has a special part. “That part of the brain is larger in musicians than in non-musicians,” Dr Chan told BBC. “If that part of the brain is larger, it may be better developed and so this explains very nicely our results.”
Dr Chan and her workmates came to their conclusion after studying students. Their research is reported in the latest edition of the journal(杂志) Nature. “We did the experiment with 60 girl college students from our university and 30 of them have at least six years training with one western musical instrument (such as the violin and the piano) before the age of 12. The other 30 had received no music training. We tested their memory by reading them some words and asking them to remember these words—a very common test for memory. We found that people who have had music training can remember about 70% more information than those who have not had any music training.”
Dr Chan thinks the process(过程) of learning is more important than the actual instrument used. She also believes if one is able to remember words through learning to play instruments, he or she could have some very real benefits. Dr Chan thinks this could be developed into a medical way for patients who are suffering from memory loss.
小题1: According to the writer, learning to play a musical instrument helps to ______.
| A．get more knowledge |
| B．live more happily |
| C．remember more words |
| D．make one become a musician |
| A．Dr Chan thinks people should have music training when they grow up. |
| B．Dr Chan thinks the special part of the brain doesn’t need developing. |
| C．Dr Chan thinks people should have music training when they are young. |
| D．Dr Chan thinks musicians have a larger brain than non-musicians. |
| A．30 girl students. | B．60 girl students. |
| C．17% of his students. | D．60 girl and boy students. |
At a certain point in our lives our body systems will begin to weaken . It may become more difficult for us to see and hear. The slow change of aging causes our bodies to lose some of their ability to bounce back from disease and injury. In order to live longer , we have always tried to slow or stop this change that leads us toward the end of our lives.
Many factors decide our health . A good diet plays an important role. The amount and the type of exercise we get are another two factors. Our living condition is yet another. But scientists studying the aging problem want to know: Why do people grow old? They hope that by studying the aging medical science they may be able to make the length of life longer.
There is nothing to be afraid of as the old age comes. Many consider the later part of life to be the best time for living. Physical activity may become less, but often we get better understanding of the world and ourselves.
What we consider the old age now may only be middle-aged some day soon. Who knows ,with so many advances in medical science happening so quickly, life length may one day be measured in centuries ,rather than in years!
小题1:The underlined phrase “bounce back ”means “__________.”
| A．jump backward | B．run fast | C．prevent | D．recover |
| A．teach people how to eat properly |
| B．discover how important the exercise is to one’s health |
| C．study the ways to slow or stop the process of aging |
| D．invent new medicine to slow down the process of aging |
| A．consider their lives have been very successful |
| B．have come through the battle of life safely |
| C．know more about themselves and the outside world |
| D．can have a good rest and enjoy themselves |
| A．Two | B．Four | C．Five | D．Six |
Sometimes we treat people from other countries unfairly, because one person from that culture did something bad．Well, has your class ever been punished just because a few kids were causing trouble? Has your whole family ever been blamed for something your little sister did? It doesn’t seem fair, does it? It’s just equally unfair to blame a whole culture for what two or three people have done.
So here are some things that you can do to help yourself understand other cultures:
①Find common ground!
Just remember that even though some people look different on the outside, that doesn’t change how they are on the inside．They still have the exact same feelings!
②________________
Because someone from another culture has been mean to you, you decide to avoid everyone from that culture．Well think about it．Why are you blaming them for something they didn’t have anything to do with? Put yourself in their shoes．How would you feel? Putting yourself inside someone else’s head can be a very powerful way to understand WHY they are acting the way they are.
③Try to make friends with people from other cultures!
You could ask them about their culture, or what it is like in their country, if they can remember, or if they have ever lived there．Try foods from their culture, or ask them about words in their language．You might be surprised at how interesting other cultures can be! You can join great discussion groups, participate in projects, and have lots of fun doing new things.
④Be aware that you’ve judged other people
If you know what you have done, it helps to make things better．Pay attention to what you think about other people．It helps.
小题1:What is mainly discussed in this passage?
| A．Why there are differences between people |
| B．What to do to understand other cultures |
| C．How people feel when they meet people from other cultures |
| D．The differences between people from different cultures |
| A．Avoid everyone from that culture! |
| B．Put all responsibilities on others! |
| C．Consider oneself first! |
| D．Don’t blame all because of one! |
| A．feel proud of | B．express ideas of |
| C．praise and enjoy | D．pay attention to |
| A．join their discussion groups | B．try foods from their culture |
| C．avoid meeting them | D．find common ground |
But after a while I couldn’t ignore the high relationship between success and rising early．On those rare occasions where I did get up early, I noticed that my productivity was almost always higher．So I set out to become a habitual early riser．But whenever my alarm went off, my first thought was always to stop that noise and go back to sleep．Eventually some sleep research showed me that I was using the wrong strategy．
The most common wrong strategy is this: You assume that if you’re going to get up earlier, you’d better go to bed earlier．It sounds very reasonable, but will usually fail.
There are two main schools(流派) of thought on sleep patterns．One is that you should go to bed and get up at the same time every day．The second school says you should go to bed when you’re tired and get up when you naturally wake up．However, I have found both of them are wrong if you
care about productivity．If you sleep at set hours, you’ll sometimes go to bed when you aren’t sleepy enough．You’re wasting time lying in bed awake and not being asleep.If your sleep is based on what your body tells you, you’ll probably be sleeping more than you need．Also, your mornings may be less predictable if yo
u’re getting up at different times．The solution for me has been to combine both methods．I go to bed when I’m sleepy and get up with an alarm clock at a fixed time．So I always get up at the same time (in my case 5 am), but I go to bed at different times every night — sometimes at 9:30pm, and other times at midnight．Most of the time I go to bed between 10-11 pm．
However, going to bed only when I’m sleepy, and getting up at a fixed time every morning is my way．If you want to become an early riser, you can try your own.
小题1:According to the passage, the underlined phrase refers to ____.
| A．people who stay up until the next morning. |
| B．people who get up early in the morning. |
| C．people who feel sleepy in the morning. |
| D．people whose productivity is the highest in the morning. |
A．Because h e / she wanted to form the habit of going to bed early and getting up early. |
| B．Because he / she had found that his / her productivity was higher when he / she got up early. |
| C．Because he / she wanted to see which of the two main schools of thought on sleep patterns was right. |
D．Because he / she was told t he high relationship between success and rising early. |
| A．going to bed after midnight． |
| B．getting up early occasionally. |
| C．pressing off the alarm to go on sleeping. |
| D．asking scholars for advice on sleeping habits. |
| A．how to become an early riser． |
| B．how to have good sleep. |
| C．wrong strategies for getting up early. |
| D．main schools of thought on sleep patterns. |
