Scientists say they have discovered a promising treatment for sleeping sickness, a killer disease that infects(感染) about 60,000 people in Africa a year．
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_____.

hy 49 years old and have come to the conclusion that it’s now or never, so I a

m taking a dive into the raw eating lifestyle.
I have to cook for my family and

prepare what they want to eat. I’m trying to plan out this better so I have some of these unusual foods ready for myself.
I’ve read several books written by Ann Wigmore and like her appr

oach to the living foods.
Last week I atte

mpted fasting（禁食）and failed. I lasted five days by having carrots, spinach, apples and other vegetarian diets I could get my hands on. I was doing fine until I drank some coffee. I kind of proved it in my mind to have the coffee but it only made me excited and then I couldn’t sleep well and felt hungry and weak. So I stopped and went back to the old way of eating with the family.
This week I started to make a drink called rejuvelac made of sprouted wheat（芽麦）. This is fairly new to do for me and the drink smelled sort of musty（发霉的）and tasted kind of like a musty lemon. The kids tasted it and almost t

hrew up but surprisingly it tasted good to me. It is supposed to help in digestion（消化）.
I’ve made some attempts to grow wheat grass. I think I have figured that out as long as I keep it away from birds and our horses. I have two habits to get rid of, drinking coffee and smoking. I quit smoking last month but something happened, so I started up again. I’m very frustrated(受挫的) with the

smoking and really have a desire to quit for good. Anyhow I will keep this updated on my progress.

I know what you’re thinking : pizza （比萨饼）? For breakfast? But the truth is that you can have last night’s leftovers in the a. m. if you want to
I know lots of women who skip breakfast （不吃早餐）, and they have a ton of different excuses for doing it . Some say they don’t have time,others think they’re “saving” calories （卡路里）, and still others just don’t like breakfast food .
But the bottom line is that eating in the morning is very important when you

’re trying to lose weight. “Eating just about anything from 300 to 400 calories would be better than nothing at all,” says Katherine Brooking , R , D , who developed the super-easy eating plan for this year’s “SELF CHALLENGE”. And even pizza can be healthy if it’s loaded with vegetables, and you stick to one small piece.
Breakfast is one meal I never miss, and the same goes for most weight loss success stories. Research shows that eating breakfast keeps you from overeating later in the day. Researchers at the University of Southem California found that breakfast skippers have a bigger chance of gaining weight than those who regularly have a morning meal.
So eat something in the morning, anything. I know plenty of friends who end up having no breakfast altogether, and have just coffee or orange juice. I say, try heating up last night’s leftovers-it may sound crazy, but if it works for you, do it! I find if I tell myself, “You can always eat it tomorrow,” I put away the leftovers instead of eating more that night. Try it,and then you may save yourself some pre-bedtime calories. And watch your body gain the fat-burning effects.
小题1: The underlined word “leftovers” in Paragraph 1 probably means__________.

A．food remaining after a meal	B．things left undone
C．meals made of vegetables	D．pizza topped with fruit

小题2: What can we infer from the text?

A．Working women usually have breakfast in a hurry.

B．Many people have wrong ideas about breakfast.

C．There are some easy ways of cooking a meal.

D．Eating vegetables helps save energy.

小题3: According to the last paragraph, it is important to____________.

A．eat something for breakfast	B．be careful about what you eat
C．heat up food before eating it	D．eat calorie-controlled food

小题4:The text is written mainly for those_____________.

A．who go to work early	B．who want to lose weight
C．who stay up late	D．who eat before sleep

You'd be forgiven for thinking that running after children each day would leave parents in the best shape of their lives.But a study has found that the mothers and fathers of young children are more unhealthy than their childless peers(同龄人）.
Mothers with young children are heavier and eat more calories and fatty foods,and consume more sugary dinks than chidless women,scientists said.And both sexes are less active than those in their age group without children.
Parents often choose quick,easily preparesd foods that are high in fat and calories,and by choosing these foods they may in turn serve them to their children,forming a cycle of unhealthy diet.
Dr.Berge,one of the study authors,said:“This isn't a study about blame,this is about spotting a very high-risk time period for parents that doctors should be aware of ,so they can offer solutions(解决办法）.”
According to the study ,mothers ate more fatty foods and drank about seven sugary drinks weekly,equal to about four chidless women.They also had an average of 2,360 calories daily,368 calories more than women without children,With that many calorise,women that age would need to be active to avoid to avoid gaining weight.
Fathers ate about the same amount of daily calories childless men and both had an average boby-mass index(指数）,but fathersgot less physical activity—about five hours weekly ,compared to almost seven hours among chidless men.
The study has several limitations－there's no data on how many women reccently had babies.Ther's also no information on the number of single parents,who likely face diet and exercise challenges.Sarah Kriger,an American dietician who works with new mothers said some of the mothers may have had postpartum(产后）depression,which might affect their eating and exercise habits.
小题1:What does the author mainly aim to tell us in the passage?

A．Childless couples live a much happier life than those with children.

B．Mothers will be unhealthy because of the postpartum deprdession

C．Couples of young children eat more fatty foods and lead unhealthier lives.

D．Fathers tend to eat high calorie foods because they should run after thrie children.

小题2:The underlined part“in the best shape”in the first paragraph means that a person .

小题3:Which of the following is NOT mentioned about mothers with children?

A．They are less active

B．They eat unhealthy foods

C．They may feel unhappy aftre having babies

D．They may lose their jobs aftre having babies

小题4:What Dr.Berge says in Paragraph 4 suggests that .

A．Parents should pay more attention to their chidren

B．doctors should do something with parents'high-risk time period

C．the study has drawn attention of doctors and young parents

D．parents should not be blamde for having an unhealthy lifestyle

小题5:We can learn from the last paragraph that .

A．the result of the study result in aan unscientific way

B．the study was carried out in an unscientific way

C．single mothers are surely facing quyite different situation

D．postpartum depression will help mothers to lead a healthier lirf

It is difficult for doctors to help a person with a damaged brain. Without enough blood, the brain lives for only three to five minutes. More often the doctors can’t fix the damage. Sometimes they are afraid to try something to help because it is dangerous to work on the brain. The doctors might make the person worse if he operates on the brain.
Dr. Robert White, a famous professor and doctor, thinks he knows a way to help. He thinks doctors should make the brain very cold. If it is very cold, the brain can live without blood for 30 minutes. This gives the doctor a longer time to do something for the brain.
Dr. White tried his idea on 13 monkeys. First he taught them to do different jobs, then he operated on them. He made the monkeys’ blood back to the monkeys’ brains. When the brain’s temperature was 10℃, Dr. White stopped the blood to the brain. After 30 minutes he turned the blood back on. He warmed the blood again. After their operations the monkeys were like they had been before. They were healthy and busy. Each one could still do the jobs the doctor had taught them.
小题1:.The biggest difficulty in operating on the damaged brain is that ____.

A．the time is too short for doctors

B．the patients are often too nervous

C．the damage is extremely hard to fix

D．the blood-cooling machine might break down

小题2:.The brain operation was made possible mainly by ____.

A．taking the blood out of the brain

B．trying the operation on monkeys first

C．having the blood go through a machine

D．lowering the brain’s temperature

小题3:.With Dr. White’s new idea, the operation on the damaged brain ____.

A．can last as long as 30 minutes

B．can keep the brain’s blood warm

C．can keep the patient’s brain healthy

D．can help monkeys do different jobs

小题4:. What is the right order of the steps in the operations?
a. send the cooled back to the brain b. stop the blood to the brain
c. have the blood cooled down d. operate on the brain

The common cold is the world's most widespread illness, which is a plague that man receives.
The most widespread mistake of all is that colds are caused by cold. They are not. They are caused by viruses passing on from person to person. You catch a cold by coming into contact directly or indirectly, with someone who already has one. If cold causes colds, it would be reasonable to expect the Eskimos to suffer from them forever. But they do not. And in isolated Arctic regions, explorers have reported being free from colds until coming into contract again with infected people from the outside world by way of packages and mail dropped from airplanes.
During the First World War, soldiers who spent long periods in the

trenches, cold and wet, seldom caught colds.
In the Second World War, prisoners at Auschwitz concentration camp, naked and starved, were astonished to find that they seldom had colds.
At the Common Cold Research Unit in England, volunteers took part in experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time. After taking hot baths, they put on bathing suits, allowed themselves to be with cold water, and then stood about dripping wet in a room. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose.
If then, cold and wet have nothing to do with catching colds, why are they more frequent in winter? Despite the most hard research, no one has yet found out the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and that makes it easier for cold viruses to be passed on.
No one has yet found a cure for the cold. There are drugs and pain-killers such as aspirin, but all that they do is to relieve the symptoms.
小题1:The writer offered ___ examples to support his argument.

小题2:Arctic explorers may catch colds when___.

A．they are working in the isolated Arctic regions

B．they are writing reports in terribly cold weather

C．they are free from work in the isolated Arctic regions

D．they are coming into touch again with the outside world

小题3:Volunteers taking part in the experiments in the Common Cold Research Unit___.

A．suffered a lot	B．never caught colds
C．often caught colds	D．became very strong

小题4:The passage mainly discusses___.

A．the experiments on the common cold

B．the fallacy about the common cold

C．the reason and the way people catch colds

D．the continued spread of common colds

Britain is set to face an increase in cold winters, with up to one-in-seven hitting the UK with longer periods of time when temperatures are below freezing, a study has suggested．The prediction was based on research that found out how low solar activi

ty affected winter weather patterns．
However, the researchers were eager to stress that their findings did not suggest that the region was about to fall suddenly into a "little ice age"．The findings appear in the journal Environmental Research Letters．"We could get to the point where one-in-seven winters are very cold, as we had at the start of last winter and all through the winter before last," said co-author Mike Lockwood, professor of space environment physics at the University of Reading．
Using the Central England Temperature （CET） record, the world's longest instrumental data series that dates back to 1659, the team said that in general temperatures during recent winters had been obviously lower than the longer-term temperatures．"The mean CET for December, January and February for the recent relatively cold winters of 2008 ~ 2009 and 2009~2010 were 3．50℃ and 2．53℃ respectively," they wrote．

"However, the mean value for the previous 20 winters had been 5．04℃．The series of lower winter temperatures in the UK during the last three years had raised questions about the probability of more similar, or even colder, winters occurring in the future．"
Last year．Professor Lockwood and colleagues published a paper that found a link between fewer sunspots and atmospheric conditio

ns that "blocked" warm westerly winds reaching Europe during winter months, opening the way for cold easterly winds from the Arctic and Russia to sweep across the region．Professor Lockwood, while acknowledging that there were a range of possible meteorological factors （气象因素） that could influence blocking events, said the latest study moved things forward by showing that there was "impro

vement in the predictive skill" when solar activity was taken into consideration．
小题1:We can know from the second paragraph that _____．

A．research shows that Britain will soon fall into an ice age

B．Mike Lockwood's research focuses on space environment physics

C．it was quite cold in Britain over the entire winter last year

D．so far one-in-seven winters have been very cold in Britain

小题2:The．underlined word "mean" in Paragraph 3 is closest in meaning to "_____"．

小题3:What can we infer from the last paragraph?

A．It was sunspots that blocked warm westerly winds reaching Europe．

B．Meteorological factors hardly have any influence on blocking events．

C．The latest study done by Professor Lockwood was of little practical value．

D．Considering solar activity or not affects the accuracy of weather forecasting．

小题4:What's the best title of the passage?

A．Another big danger approaching the UK

B．Research finds out solar activity is to blame for the cold

C．UK faces more cold winters due to weaker solar activity

D．Changes in weather patterns should be responsible for low solar activity

Depression(抑郁症)is a serious problem today．Depression causes workers to be unproductive，causing companies and countries to lose billion of dollars．One expert says that depression is like cancer because it is “widespread, costly and deadly”．Depression hits one person in five around the world．
Although people have believed depression to be a problem among the rich and educated，studies show that depression is a problem among everyone．Over any six-month period, between five to seven percent of the world’s population will be suffering from a serious depression．
Suicide(自杀)rates among people suffering from the disease in its extreme, or clinical form were 80 percent higher than in the population at large, and sufferers were four times more likely to have heart attacks．People who suffer from depression often have problems sleeping，getting up on time，and doing work productively.
Depression, which researchers agree has its origin in the genes(基因)，brings loss of confidence and ability to concentrate, making it possible for employees and managers to work efficiently．
Depression is made more serious in China by Chinese’s inability to face it．Many people believe that depressed people are either weak or lazy．Besides，there is no good treatment，with few specialists available．
“Most patients in China just don’t get help,” a Chinese doctor says．“In my hospital，I have
to see 30 or 40 patients in a morning，and just have time to say ‘Hello，how do you feel ?…’”
In Western countries，people are not afraid to admit that they have depression，but most do not tell it to their boss，because they fear that their boss would fire them．
“In my e

xperience，aging bosses are the most willing to admit they have it, because they feel
the most secure about themselves, ” an American doctor says．
Hopefully，in the near future，people around the world will be able to admit that they have depression so that they can get the right treatment.
小题1:Which of the following is TRUE according to the passage?

A．It is widely believed that everyone may suffer from depression．

B．Depression brings great problems to its sufferers in their life and work．

C．Depression is a commonly-

existing problem only in rich countries．

D．The poorer and the less educated a person is，the less he will suffer from depression．

小题2:Compared to normal people，depressed people are likely to be________．

A．very unconfident and often absent-minded	B．easy to avoid being hit by heart attacks
C．working efficiently and productively	D．either weak or lazy

小题3:Depression becomes more serious in China because of_________．

A．the understanding of the problem	B．the lack of treatment and doctors
C．their unwillingness to tell it to their boss	D．the doctors’ careless work

小题4:What can we infer from the passage?

A．People are suffering from depression because of the shortage of specialists．

B．The aging bosses around the world dare to say they are depressed．

C．More and mote patients will turn to specialists for help

D．Western people are braver than Chinese people
