Most people, when they travel to space, would like to stay in orbit for a few days of more. And this stands to reason, if you’re paying $20,000 for your trip to orbit! Strain order for tourism to reach its full potential there’s going to be a need for orbital accommodation---or space hotels. What would a space hotel actually be like to visit? Hotels in orbit will offer the services you expect from a hotel------private rooms, meals, bars. But they’ll also offer two unique experiences: impressive views----of Earth and space---and the endless entertainment of living in zero gravity---including sports and other activities that make use of this.
The hotels themselves will vary greatly----from being quite simple in the early days to huge luxury structure at a later date. It’s actually surprising that as later as 1997, very few designs for space hotels were published. This is mainly because those who might be expected to design them haven’t expected launch costs to come down far enough to make them possible.
Lots of people who’ve been to space have described vividly what it’s like to live in zero gravity. There are obviously all sort of possibilities for dancing, gymnastics, and zero-G sports. Luckily, you don’t need to sleep much living in zero gravity, so you’ll have plenty of time for relaxing by hanging out in a bar with a window looking down at the turning Earth below.
Of course all good things have come to an end. Unfortunately, And so after a few days you’ll find yourself heading back enough you’ll be much more expert at exercising in zero gravity than you were when you arrived. You’ll be thinking how soon you can save up enough to get back up again---or maybe you should change jobs to get to work in an orbiting hotel.

Any diet on which you eat fewer calories than you need to get through the day — like an 800-calorie-per-day diet can be dangerous. Diets that don't allow any fat also can be bad for you. Everyone needs a certain amount of fat in their diet — up to 30% of total calories — so no one should eat a completely fat-free diet.
Don't have diets that restrict （限制）certain food groups, either. A diet that requires you to say no to bread or pasta or allows you to eat only fruit is unhealthy. You won't get the vitamins and minerals you need. And although you may lose weight, you'll probably gain it back as soon as you start eating normally again.
Some people start dieting because they think all the problems in their lives are because of weight. Others have an area of their lives that they can't control, like an alcoholic parent, so they focus on something they can control — their exercise and food intake.
People who diet may get lots of praise from friends and family when they start losing pounds, which makes them feel good. But eventually a person reaches a weight level — and doesn't lose as much weight as before because the body is trying to keep a healthy weight, so they aren't any happier.
Some people may find it hard to control their eating, so they stick with an extreme diet for a little while, but then eat tons of food. Feeling guilty about the binge, they use laxatives（瀉藥）. Eating too little to maintain a healthy weight or eating only to throw up the calories are both eating disorders, which are harmful to a person's health.
1. Which is not the result of restricting certain food groups?
A. lose weight for a short period         B. unhealthy  
C. short of nutrition                     D. hungry
2. The reasons why some people start and keep dieting DON’T include__________.
A. They think their trouble comes from their weight.
B. They have an alcoholic parent.
C. Other people’s praise when they lose some weight.
D. There is something they can’t control except food intake.
3. The underlined phrase in the last paragraph refers to _________.
A. a fat-free diet               B. a special diet   
C. eating too much            D. eating too little
4. Which of the following statements is true?
A. A person needs about 800 calories each day.
B. A person who doesn’t eat bread is unhealthy.
C. An improper diet may cause eating disorder.
D. Fat takes up the most part of calories inside body.
5. According to the passage, when people want to lose weight, they should_________.
A. avoid eating some food that can lead to being fat   B. control their eating amount and times
C. have a healthy and balanced diet                D. throw up some of what they eat  

There are various reasons why cancers appear to be on the increase. For one thing, though their sufferers are to be found in all age groups, cancers are particularly likely to attack persons in their middle and advanced years. Naturally, since people live longer these years, there are more cancer sufferers than before. Again, with better methods of diagnosis (診斷), doctors can more easily recog­nize cancerous growths that would formerly have passed unnoticed or that would have been wrongly di­agnosed. It is also believed that certain habits and conditions of modem living, including heavy smok­ing and the pollution of the air, may leave people living in more cancer-causing conditions than before.
We all look forward to the day when a simple medical test can find cancer while it is still small. Researchers around the world are working on such a test. Most of their work deals with the examina­tion of the blood.
Researchers in Boston have found something in the blood of cancer patients that does not appear in healthy persons. The test showed which persons had cancer and which did not. It was correct more than 90 percent of the time.
The researchers believe the test may be able to show cancer very clearly in its development. Cancers discovered early usually can be treated successfully.
The test examines very small bits of fat in the blood called lipids (脂質(zhì)). Cancers seem to change lipids although doctors do not know why. The test showed differences between the lipids of the persons with cancer and the lipids of those without cancer.
The researchers say the new test could be a step to develop a simple way to check patients for cancer before the disease shows on an X-ray.
1. Who will fail cancer from the study of the researchers?
A. The young.                         B. The middle age and the older.
C. The man.                                  D. The woman.
2. The underlined words "such a test" refer to________.
A. the test that shows which persons have cancer and which don’t     .
B. the test that may be able to show cancer very early in its development,.
C. a simple medical test that cannot find cancer when it is -small
D. a new test that could be a step to develop a difficult way
3. Which of the following statements is true according to the passage?
A. Cancers have much to do with something in patients’ blood.
B. People living in better conditions are most likely to be attacked by cancer.
C.X-raying is the best way to determined whether a person has cancer or not.
D. Cancers have nothing to do with a person’s habits and living conditions.
4. What would be the best title for the passage?
A. A simple way to cancer                B. Cancers can be cured
C. How to find cancer                          D. Early discovery of cancer

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.
6. 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 w*w
7. 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
8. 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
9. 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
A. a, b, c, d    B. c, a, b, d    C. c, b, d, a    D. b, c, d, a
10. Which of the following is not true?
A. If there isn’t enough blood, the brain can live for only three to five minutes.
B. If the brain is very cold, it can live without blood for half an hour.
C. Dr. White tried his idea for thirteen times.
D. After their operations, the monkeys were healthy and busy again

“Children who eat less salt and drink fewer sugar-sweetened soft drinks may significantly lower their risks of obesity,” researchers recently reported in the journal Hypertension.
“Sugar-sweetened soft drinks are a significant source of calorie intake in children,” said Feng J. He, a researcher at St George’s University of London, England. “It has been shown that sugar-sweetened soft drink consumption is related to obesity in young people.” They wanted to know whether there is a link between salt intake and sugar-sweetened soft drink consumption.
Dr He and colleagues analyzed data from a 1997 national survey of more than 2,000 people between 4 and 18 in Britain. “We found that children eating a lower-salt diet drank less fluid,” said He. “From our research, we estimated that 1 gram of salt cut from their daily diet would reduce fluid intake by 100 grams per day.”
The researchers also found that children eating a lower-salt diet drank fewer sugar-sweetened soft drinks. From their research, they predicted that reducing salt intake by 1 gram each day would reduce sugar-sweetened soft drink consumption by 27 grams per day, after. “If children aged 4 to 18 cut their salt intake by half, there would be a decrease of about two sugar-sweetened soft drinks per week per child, so each child would decrease calorie intake by almost 250 kilocalories per week,” Dr He said.
In previous studies, researchers found that a low-salt diet lowers blood pressure in children, and prevents the development of high blood pressure later in life. “Both high blood pressure and obesity increase the risk of having strokes and heart attacks,” Dr He said.
Dr He recommends that parents check labels and choose low-salt food products. “Small reductions in the salt content of 10 to 20 percent cannot be detected by the human salt taste receptors (感受器) and do not cause any technological or safety problems,” Dr He said.
小題1:According to the passage, obesity is directly linked to ______.

A．high-salt foods

B．sugar-sweetened soft drinks

C．high blood pressure

D．strokes and heart attacks

小題2:Compared with previous studies, the recent one found that ______.

A．a(chǎn) lower-salt diet may mean less sugar-sweetened soft drink consumption

B．a(chǎn) low-salt diet keeps children out of high blood pressure

C．children face the risk of having strokes and heart attacks

D．low-salt food products do not do harm to people’s health

小題3:Which of the following statements would Dr He agree to?

A．The less salt people eat, the healthier people become.

B．Children should reduce fluid intake in their daily life.

C．No high-salt food products will be available in shops.

D．A low-salt diet may prevent both high blood pressure and obesity.

小題4:After reading the passage, who should take effective action?

A．Children.

B．Parents.

C．Doctors.

D．Researchers.

Health experts have long worried about the increasing rate of obesity in kids. It’s an important concern: Being weight or obese during childhood can lead to serious problems normally seen in adults, such as diabetes and high blood pressure. Poor diets and a lack of exercise are usually the causes. But would you ever have imagined there might be a connection between the bacteria that lived in your guts （內(nèi)臟）when you were a baby and the chance that you would become overweight?
Scientists in Finland recently found just such a link. In a recent study, they showed that overweight kids had different species of bacteria living in their guts.
You probably think of bacteria only as germs that can make you sick. While it’s true that some bacteria can make people ill, your body actually depends on some types of bacteria to help you digest food and extract nutrients from it. These “good” bacteria live in your guts, where they process the food you eat.
Human babies get these bacterial helpers from their moms. When a baby is born, some of the bacteria in the mother move into the baby’s body. Growing babies get additional “good” bacteria from the milk their mothers produce. And it turns out the bacteria might play an important role in regulating weight just six years later.
So how could these bacteria affect weight? The researchers still haven’t tested that question, but future tests might lead to an answer.
小題1:The “l(fā)ink” in Paragraph 2 refers to the relationship between _______.

A．bacteria and the chance of being overweight

B．obesity and diabetes

C．diets and the chance of being overweight

D．bacteria and exercise

小題2:Which of the following is NOT the function of “good” bacteria?

A．Helping to digest food.

C．Helping to regulate weight.

D．Making a person ill.

小題3:The purpose of writing this passage is to _______.

A．introduce the role of bacteria in children’s weight

B．a(chǎn)nalyze the influence of obesity on kids

C．give advice on how to lose weight quickly

D．explain the function of bacteria in foods

Ways to Burn More Calories
Run through water
Running in water is one of the toughest activities you can perform because the wet stuff is about 12 to 15 times as resistant (具有阻力的) as air. Try your hardest to run and you can burn about 17 calories per minute.
Start fast
Don’t be fooled — slow and steady won’t win the race. A recent study found that after a short warm-up, cyclists who rode hard during the first half of their workouts and then slowed for the second half burned about 10 percent more calories than those who started slow and finished fast.
Take to the sand
Here is some easy-to-remember advice on burning calories: the softer the surface, the more you burn. By walking or running on the beach, you can use up 20 to 50 percent more calories than you do going at the same pace on a hard trail.
Shut up and dance
Here’s the perfect excuse to sign up for that hip-hop dance class you’ve been eager to try. Surprising your body with new activities — dance, a new sport, you name it — forces it to work harder because it’s doing unfamiliar movements and using muscle groups in different ways.
Use your arms
Getting both your upper and lower body involved can provide a big calorie-burning advantage. So if you’re short of time or want to get everything you can out of your usual 45-minute workout, try total-body activities such as rowing ormming. You can evenng your arms as hard as you can while you walk.
小題1: How can water help you burn more calories?

A．By pushing your body.

B．By wetting your clothes and shoes.

B．One can burn more calories when walking on stones than on earth.

C．One can burn more calories when running in water than on the sand.

D．One can burn more calories when exercising using the upper body than using the lower body.

Why do men die earlier than women? The latest research makes it known that the reason could be that men’s hearts go into rapid decline when they reach middle age.
The largest study of the effects of ageing on the heart has found that women’s longevity may be linked to the fact that their hearts do not lose their pumping power with age.
“We have found that the power of the male heart falls by 20-25 percent between 18 and 70 years of age,” said the head of the study, David Goldspink of Liverpool John Moores University in the UK.
“Within the heart there are millions of cells that enable it to beat. Between the age of 20 and 70, one-third of those cells die and are not replaced in men,” said Goldspink. “This is part of the ageing process.”
What surprises scientists is that the female heart sees very little loss of these cells. A healthy 70-year-old woman’s heart could perform almost as well as a 20-year-old one’s.
“This gender difference might just explain why women live longer than men,” said Goldspink. They studied more than 250 healthy men and women between the ages of 18 and 80, focusing on healthy persons to remove the confusing influence of disease. “The team has yet to find why ageing takes a greater loss on the male heart,” said Goldspink.
The good news is that men can improve the health of their heart with regular exercise. Goldspink stressed that women also need regular exercise to prevent their leg muscles becoming smaller and weaker as they age.
小題1:The underlined word “l(fā)ongevity” in the second paragraph probably refers to “________”.

A．health

B．long life

C．a(chǎn)geing

D．effect

小題2:The text mainly talks about ________.

小題3:According to the text, the UK scientists have known that ________.

A．women have more cells than men when they are born

B．women can replace the cells that enable the heart to beat

C．the female heart loses few of the cells with age

D．women never lose their pumping power with age

小題4: If you want to live longer, you should ________.

A．enable your heart to beat much faster

B．find out the reason for ageing

C．exercise regularly to keep your heart healthy

D．prevent your cells from being lost

小題5:We can know from the passage that ________.

A．the reason why ageing takes a greater loss on the male heart has been found out

B．scientists are on the way to finding out why the male heart loses more of the cells

C．the team has done something to prevent the male from suffering the greater loss

D．women over 70 could lose more heart cells than those at the age of 20
