Mom noticed that something was wrong when I started getting so thirsty, I’d have a lot to drink before bed, which was unusual for me. One time, I opened a big container of apple juice and kept refilling my glass. Before I knew it, I’d drunk the entire container! My mom call my doctor. I then had a few blood tests, and the results were certain ------ I had diabetes, which meant that the amount of sugar in my blood was very high. That can be dangerous, so I had to learn how to control my blood-sugar level.
My eating habits had to change in a big way. With diabetes, I can’t eat a lot of sugar or carbohydrates. I have to figure out exactly how much sugar I plan to eat, and then I get an injection of insulin before the meals to help my body process the food. Also, I test my blood-sugar level often. I’m always trying to keep my blood sugar at a healthy level. The level can drop when I exercise, but that doesn’t keep me out of gym class or off the basketball court ------ I just keep some juice boxes around to boost my blood sugar if I need to.
It’s a lot of work ------ and not a lot of fun ------ to keep track of everything, but I’ve gotten used to my new habits. I was a little scared at first because I wasn’t sure how my life would change. Once I knew what I needed to do, though, it wasn’t a big deal. My life is different now from what it was before, but it has become completely regular to me.

What kind of sports impressed you most during your childhood? Maybe racing around the playground or skipping rope for hours would bring you pleasure. At that time you weren’t thinking of fitness, you were just thinking of entertainment. But in this age of high-tech home equipment and underused gym memberships, the simple joy of jumping rope has been forgotten. I think rediscovering it probably will give you a total-body exercise.
Although considered an excellent form of exercise, jumping rope has never received widespread acceptance because of two reasons. First,most people recognize jumping rope as an excellent form of cardiovascular (心血管的) exercise, but they also believe that it is simply too difficult. In other words, they don’t think they’ll be able to continue jumping for the near 20 minutes in order to achieve a beneficial physical effect. Second, many regard it as somewhat boring and overly repetitive —not as something fun or enjoyable.
As a matter of fact, jumping rope can be great fun as long as you find a proper way to practise it. Instead of doing the usual two-foot bounce(跳) over and over again, players good at rope-jumping often change their pattern every 10 or 20 jumps. A single bounce, a double –bounce , a skip, a knee-up, side swings , as well as a variety of other easy-to-learn free-style rope-jumping .
Nowadays researchers are discovering that jumping rope also prepares the brain for learning . It is an exercise allowing both brain hemispheres（半球）to perform equallyto each other . In short, jumping rope can be a life-long activity requiring little equipment, time and space , yet leading to a much healthier life.
小题1:The main purpose of the first paragraph is to tell us that         .
A．people would rather have exercise in a gym than do sports outside
B．there seems to be too much advanced equipment for people to use
C．racing around the playground was regarded as children’s favorite sport
D．jumping rope has escaped from people’s memories in modern society
小题2:One reason that can explain why rope jumping has not spread widely is that_____.
A．it benefits the cardiovascular system
B．it is too difficult for people to learn to jump
C．it is believed to be boring and repetitive
D．it requires little equipment, time and space
小题3:The first sentence in Paragraph 3 implies that       in rope jumping .
A．there is only one proper way to follow
B．the usual way should not be used again
C．the easiest way is always the best one
D．there are different kinds of ways to follow
小题4:According to the researchers , jumping rope          .
A．only prepares the brain for learning
B．is suitable for students only
C．helps both brain hemispheres work together
D．can be dangerous for old people
小题5:What is the author’s attitude towards rope jumping ?
A．He strongly argues against it.
B．He is in favour of it.
C．He is sitting on the fence of it .
D．He knows little about it .

Medical drugs sometimes cause more damage than they cure. One solution to this problem is to put the drugs inside a capsule, protecting them from the body—and the body from them—until they can be released at just the right spot. There are lots of ways to trigger (引发) this release, including changing temperature, acidity, and so on. But triggers can come with their own risks—burns, for example. Now, researchers in California have designed what could be a harmless trigger to date: shining near-infrared light (NIR, 近红外线) on the drug in the capsule.
The idea of using light to liberate the drug in the capsule isn’t new. Researchers around the globe have developed polymers (聚合物) and other materials that begin to break down when they absorb either ultraviolet (UV, 紫外线) or visible light. But tissues also readily absorb UV and visible light, which means the drug release can be triggered only near the skin, where the light can reach the capsule. NIR light largely passes through tissues, so researchers have tried to use it as a trigger. But few compounds (化合物) absorb NIR well and go through chemical changes.
That changed last year when Adah Almutairi, a chemist at the University of California, San Diego, reported that she and her colleagues had designed a polymer that breaks down when it absorbs NIR light. Their polymer used a commercially available NIR-absorbing group called o-nitrobenzyl (ONB). When they catch the light, ONB groups fall off the polymer, leading to its breakdown. But ONB is only a so-so NIR absorber, and it could be poisonous to cells when it separates from the polymer.
So Almutairi and her colleagues reported creating a new material for capsules that’s even better.This one consists of a long chain of compounds called cresol groups linked in a polymer. Cresol contains reactive(易反应的) components that make it highly unstable in its polymeric form, a feature Almutairi and her colleagues use to their advantage. After polymerizing the cresols, they cap each reactive component with a light-absorbing compound called Bhc. When the Bhcs absorb NIR light, the reactive groups are exposed and break the long polymer into two short chains. Shining additional light continues this breakdown, potentially releasing any drugs in the capsule. What’s more, Almutairi says, Bhc is 10 times better at absorbing NIR than is ONB and is not poisonous to cells.
小题1:According to the passage, which of the following could be the best trigger?
A．Temperature change.B．NIR light.C．Acidity change.D．UV light.
小题2:Why is ONB unsatisfactory?
A．It breaks down when it absorbs NIR light.
B．It falls off the polymer and triggers drug release.
C．It has not come onto the market up till now.
D．It is not effective enough and could be poisonous.
小题3:Which word can be used to complete the following process of changes?
A．protectedB．formedC．exposedD．combined
Healthy Diet“An apple a day keeps the doctor away.” Similarly, if we drink a little more water ever day, we may find that we need to go to the doctor a lot less often. A healthy diet is made up of water and a great many different kinds of foods. We know that healthy foods like fruits, vegetables and fish, are important as they provide us with energy and fibre, without giving us too much fat and sugar. But why is water important?
The human body needs water to survive. Water is important as it carries poisons and waste out of our bodies. However, doctors advise us to drink plenty of water, much more than the small amount we need to stay alive.
Some doctors believe that water is important for our health in all kinds of ways. They believe that a great many illnesses and health problems stars as a result of dehydration—a lack(缺少) of water in the body. Most people are dehydrated at least some of time, although they probably don’t know it. It is surprising to learn that if we feel thirsty, we are already in the first stages of dehydration. In fact, we are advised to drink water before we feel thirsty.
These doctors think that health problems such as headaches, high blood pressure and asthma could be helped if people drink more water. They also believe that drinking more water can help people who are overweight. Water contains no calories so it will not make us put on weight. If we drink water, we will probably drink less sugary soft drinks such as Coca-cola. Doctors also believe that drinking more water may stop people from overeating. They say that many people think that they are hungry when they are, in fact, thirsty. Doctors suggest, therefore, that we eat less food and drink more water.
There are still many health problems that cannot be solved by drinking water, so we should not stop going to seeing the doctor completely. However, if we make a decision to drink water every day, we may find that we need to go to the doctor a lot less often.
小题1:We need _____for a healthy diet.
A．fibreB．foodC．waterD．Water and different foods
小题2:From the text, we know water can carry_________.
A．energy and fibre in our bodies
B．fruit, vegetables and fish in our bodies
C．sugar and fat out of our bodies
D．poisons and waste out of our bodies
小题3:Some doctors think that________.
A．people eat too much sugar
B．water is not important for our health
C．we should go to the doctor less often
D．some health problems are caused by a lack of water
小题4: Lack of water caused people to put on weight too much because_______.
A．they think they are hungry and eat too much
B．they think they are thirsty and eat less
C．water has no calories
D．it makes them hungry

More and more scientific experiments prove that physical exercise can reduce the dangers of some illnesses in middle-aged persons．Exercise strengthens the heart muscle，reduces blood pressure and help to prevent muscles from changing into fat．Physical exercise is just as important for children．
Exercise and food affect growing speed in young lab animals．Baby mice start running as soon as they are big enough to use an exercise wheel in their cage．If  they get extra food and run a lot，they will grow as much as 1.5 times bigger than normal．
The same differences in growing speed might be found between active and inactive children．Physical exercise helps active children grow faster than inactive children．One experiment shows that the brains of the mice that had enough exercise weighed about 3％more than those of the mice that did not exercise The mice that exercised are much quicker to learn doing new exercise than the mice that did not exercise．
The results of the experiments suppose the theory that exercise can help babies learn to talk and walk sooner than expected．
The good effects of physical exercise are not limited to children and middle-aged people．Exercise continues to be an important part of our lives after we grow old．For example，people over 50 years old begin to lose calcium(钙) from their bones，which get weaker and can break easily．Physical exercise，however，helps to strengthen the bones and to prevent them from losing calcium．Of course，old people can take medicines to prevent themselves from suffering from losing calcium．But the medicines they take increase the chance of developing some kind of cancer(癌)．So physical exercise is a much safer treatment(治疗)．
小题1:From the passage we know that         .
A．mice need to eat more and exercise more
B．children need more exercise than other people
C．old people like to take medicine to treat their illnesses
D．middle-aged people are easy to get fat
小题2:Active children        than inactive children．
A．enjoy walking more
B．are cleverer and healthier
C．are stronger but more foolish
D．are cleverer but weaker
小题3:Why are the bones of old people easy to break according to the passage?
A．Because they are easy to become ill．
B．Because they eat less than other people．
C．Because they have less exercise than other people．
D．there is less calcium in their bones than in those of other people．
小题4:The passage tells people that       .
A．only middle-aged persons can benefit from physical exercise
B．physical exercise can do good to both the middle-aged and children
C．people of different ages can all benefit from physical exercise
D．physical exercise is the safest treatment for losing calcium
A single night of taking the drug Ecstasy (摇头丸) can cause serious brain damage and speed up the start of Parkinson’s disease（帕金森综合症）, scientists say. Just two or three Ecstasy tablets can permanently destroy brain cells that affect movement and reasoning, according to American research that links the drug to Parkinson’s for the first time.
A study by a team at Johns Hopkins University in Baltimore, Maryland, involving squirrel monkeys and baboons (狒狒) found that both species suffered permanent damage to key cells, which are lost in Parkinson’s, after receiving three low doses（剂量）of Ecstasy at three-hour periods.
The study is particularly important because baboons are one of the best animal models for the human brain. George Ricaurte, who led the research, said that the widespread abuse of drug might have caused severe damage. “The most troubling result is that young adults using Ecstasy may be increasing their risk of developing Parkinsonism as they get older.”
Alan Leshner, a former director of the US National Institute on Drug Abuse, said, “This study emphasizes the multi-aspect damage that Ecstasy causes to users. We’ve long known that repeated use damages brain cells. But this study shows that even very occasional（偶尔） use can have long-lasting effects on many different brain systems. It sends an important message to young people: don’t experiment with your own brain.”
Janet Betts, a mother whose teenage daughter Leah died after a single Ecstasy tablet in 1995, said, “This comes as no surprise. But people can’t see the effects at first, and they say it won’t happen to them. We’ll see the symptoms later, just as we have with smoking.”
小题1:The article is intended to ______.
A．explain the bad effects of drugs on people’s health
B．warn young people of the risk of taking the drug Ecstasy
C．persuade people out of such bad habits as smoking and using drugs
D．tell us the links between the drug Ecstasy and the animal models
小题2:We know from the passage that a low dose of Ecstasy ______.
A．can permanently destroy one’s brain cells
B．can cause serious brain damage occasionally
C．will result in immediate symptoms
D．may bring on Parkinson’s at once
小题3:Why are squirrel monkeys and baboons involved in the experiments?
A．Because these animals usually take drugs.
B．Because their brain is similar to human beings.
C．Because there is a model in the animals’ brains.
D．Because they will soon get well after the experiment.
小题4:The underlined word “it” in the last paragraph probably refers to”        ”.
A．Leah’s death after a single tablet
B．the symptoms after smoking
C．the damage to the brain systems
D．repeated use of the drug
In the United States, 30 percent of the people have a “weight problem”. To many people the cause is obvious (明显的): they eat too much. But scientific evidence (证据) does little to support this idea. Going back to America of 1910, we find that people were thinner than today, yet they ate more food. In those days people worked harder physically, walked more, used machines much less, and didn’t watch television.
Several modern studies, moreover, have shown that fatter people don’t eat more on average than thinner people. A 1979 study of 3,545 London office workers showed that fat people eat less than slim (苗条的) people.
Studies also show that slim people are more active than fat people. A study by a research group at Stanford University found the following interesting facts:
The more the man ran, the greater loss of the body fat.
The more they ran, the greater increase in food intake.
Thus, those who ran the most ate the most, yet lost the greatest amount of body fat.
小题1: Nowadays many Americans have the problem that ______.
A．they are too slim B．they work too hard
C．they are too fatD．they lose too much body fat
小题2: According to the passage, how many people in 900 Americans have a “weight problem”?
A．150.B．300.C．600.D．270.
小题3:Is there any scientific evidence to support the idea that eating too much is the cause of a “weight problem”?
A．Yes, there is plenty of evidence.
B．Of course, there is some evidence to support this.
C．There is hardly any scientific evidence to support this.
D．We are not sure.
小题4:The Americans in 1910 ________.
A．ate more food and had more physical activities
B．ate less food but had more physical activities
C．ate less food and had less physical activities
D．had more problems
Bend over, take a deep breath and drink some water! This is just one of the hundreds of tips you might get if you have the hiccups(打嗝). Hiccups are so mysterious. We really don’t know why they start and why they stop.
Everyone has a favorite cure for a case of the hiccups. Some people think that a good scare is necessary to get well. Others eat a teaspoon of sugar. Still others drink a glass of water with a knife in it.
An American man named Jack O’Leary claimed to have hiccupped 160 million times over a period of eight years. He tried 60,000 cures, but none of them worked. Finally he prayed to Saint Jude, the saint of Hopeless cases, and his hiccupping stopped immediately.
It took a British plumber eight months to cure his hiccups. People from all over the world wrote him letters with suggestions for getting well. He tried them all, but the hiccups continued. Finally, he drank a “secret’’mixture someone had sent him. By that evening his hiccups were gone. Why did these cures work for these two men? No one really knows. But people who have studied many cases of hiccups have an idea. Hiccups usually go away if you believe in the cure.
小题1:
________might be the best cure for hiccups.
A．Special pillsB．A spoonful of saltC．Cold waterD．What you believe in
小题2:
The plumber spent________in stopping his hiccups.
A．4 hoursB．2 daysC．8 monthsD．8 years
小题3:
According to the passage, which of the following is TRUE?
A．We know why the hiccups start, but we don’t know how to stop them.
B．Saint Jude is an expert in curing the hiccups.
C．The British plumber drank a secret mixture given by an experienced doctor and then became well.
D．Some people think that a good scare is a cure for a case of hiccups.
小题4:
What is the main idea of this passage?
A．Different ways to stop hiccupsB．What makes hiccups happen
C．How to get hiccupsD．Jack O’Leary’s hiccups
