“We all know that exercise is good for us, but can you get the benefits without actually doing the exercise?” asks Michael Mosley.

Having a hot bath or a sauna is a good way to soothe your limbs after exercise, but what happens if you do it instead of exercise? Dr. Steve Faulkner of Loughborough University asked me to take part in an experiment comparing the relative benefits of having a long, hot bath versus an hour of hard pedalling.

For this study I join a group of volunteers who have all been fitted with monitors which continuously record blood sugar levels. Keeping your blood sugar levels within the normal range is an important measure of your “metabolic” fitness.

The first part of the experiment is very relaxing, consisting of having a long, hot bath. While I sit in the bath, which they keep at 40℃, Steve closely monitors my core temperature. Once it has risen and stayed there, I am allowed out.

A couple of hours after my bath I have a light meal. Since we want to see how having a hot bath compares with exercise we repeat the experiment.

So what’s the result?

“One of the first things that we were looking at,” Steve says, “is the energy expenditure while you’re in the bath and what we found was an 80% increase in energy expenditure just as a result of sitting in the bath for the course of an hour.”

This is nothing like as many calories as cycling for an hour (which comes out at an average of 630 calories) but we do burn 140 calories, the equivalent of a brisk 30-minute walk.

1.What is the meaning of the underlined word in Paragraph 2?

A. exercise　　 B. strengthen　　 C. relax　　 D. build up

2.What is the purpose of the experiment?

A. To compare energy expenditure of hot bath and pedalling

B. To tell people how to lose weight.

C. To show the benefit of hot bath.

D. To encourage people to have a hot bath instead of pedalling.

3.What does normal sugar level mean?

A. It means you are healthy.　　 B. It means your temperature is normal.

C. It means you don't need exercise.　　 D. It means your metabolic system is normal.

4.If you want to burn 600 calories, what can you do?

A. Have a hot bath for one hour.　　 B. Cycle for one hour.

C. Have a brisk 60-minute walk.　　 D. Have a brisk 30-minute walk.

It is easy for us to tell our friends from our enemies. But can other animals do the same? Elephants can! They can use their sense of vision and smell to tell the difference between people who pose a threat and those who do not.

In Kenya, researchers have found that elephants react differently to clothing worn by men of the Maasai and Kamba ethnic groups. Young Maasai men spear animals and thus pose a threat to elephants; Kamba men are mainly farmers and are not a danger to elephants.

In an experiment conducted by animal scientists, elephants were first presented with clean clothing or clothing that had been worn for five days by either a Maasai or a Kamba man. When the elephants detected the smell of clothing worn by a Maasai man, they moved away from the smell faster and took longer to relax than when they detected the smells of either clothing worn by Kamba men or clothing that had not been worn at all.

Garment color also plays a role, though in a different way. In the same study, when the elephants saw red clothing not worn before, they reacted angrily, as red is typically worn by Maasai men. Rather than running away as they did with the smell, the elephants acted aggressively toward the red clothing.

The researchers believe that the elephants’ emotional reactions are due to their different interpretations of the smells and the sights. Smelling a potential danger means that a threat is nearby and the best thing to do is run away and hide. Seeing a potential threat without its smell means that risk is low. Therefore, instead of showing fear and running away, the elephants express their anger and become aggressive.

1.According to the passage, which of the following statements is true?

A. Maasai people are a threat to elephants.

B. Kamba people raise elephants for farming.

C. Both Kamba and Maasai people are elephant hunters.

D. Both Kamba and Maasai people traditionally wear red clothing.

2.How did the elephants react to smell in the study?

A. They attacked a man with the smell of new clothing.

B. They needed time to relax when smelling something unfamiliar.

C. They became anxious when they smelled Kamba-scented clothing.

D. They were frightened and ran away when they smelled their enemies.

3.What is the main idea of this passage?

A. Elephants attack people who wear red clothing.

B. Elephants use sight and smell to detect danger.

C. Scientists are now able to control elephants’ emotions.

D. Some Kenyan tribes understand elephants’ emotions very well.

4.What can be inferred about the elephant’s behavior from this passage?

A. Elephants learn from their experiences.

B. Elephants have sharper sense of smell than sight.

C. Elephants are more intelligent than other animals.

D. Elephants tend to attack rather than escape when in danger.

We all know that eating junk food can make us fat. However, a new study suggests that it can do more than that – it can also make us lazy, reported CBS News.

In the study, researchers at the University of California, Los Angeles, US divided 32 female rats into two groups. The first group was fed a diet of healthy food such as corn and fish, while the second was given a diet of highly processed (加工的) food rich in sugar, namely “junk food”.

Within three months, the rats in the second group were already much fatter than those on the healthy diet. And when researchers trained the rats to do simple tasks, they found even more differences between the two groups rather than weight.

During the task – pushing a lever (杠杆) to receive a reward of sugar water – the rats on the junk food diet were found to be less willing to move, and they took longer breaks between each push than the lean rats did.

“It is as if the rat is thinking ‘This is too much work’,” Aaron Blaisdell, leader of the study, told the Los Angeles Times.

But what about the possibility that the fat rats were less passionate about getting sugar water because they were already eating lots of sugar in their daily diet? That’s why researchers repeated the tests by rewarding fat rats with plain water when they were extremely thirsty. However, the results came out just the same.

According to researchers, these differences suggest that junk food changed the chemistry in the rats’ brains.

The experiment didn’t end there. After six months, the rats’ diets were switched, and the overweight rats were given a healthy diet for nine days. However, this change didn’t help reduce their weight or improve their ability to perform tasks, which means the effects of their junk food diet persisted (持续存在). “There’s no quick fix,” said Blaisdell.

For a long time, we’ve believed that people become fat because they are lazy. But this study has proven the opposite to be true as well, which indicates that laziness and obesity are a “vicious cycle (恶性循环)”.

So, if you constantly feel tired, lacking any urge to get up from your chair, it could be that you’ve been studying too hard. But you should also pay attention to your diet.

1.During the first three months of the experiment by researchers at the University of California, ______.

A. rats from the healthy diet group ate nothing but corn and fish

B. rats on the junk food diet ate more than those on healthy diet

C. rats on the healthy food diet performed better at simple tasks than those on the junk food diet

D. rats on the junk food diet seemed uninterested in sugary food

2.The researchers rewarded thirsty rats with plain water in the lever test to ______.

A. help them control their weight

B. test whether fat rats lost interest in the test because they had taken enough sugar

C. change the diet habits of fat rats

D. find out the influence of sugar on rats’ brains

3. The underlined word “there” refers to ______.

A. after the rats on the junk food diet had worked hard to get sugar water

B. after the type of food rats prefer had been identified

C. after a quick cure for obesity had been found

D. after the fact that fatter rats are lazier than lean rats had been found

4.We can conclude from the article that ______.

A. fat people are usually lazier than lean people

B. people should switch between different types of diets to keep healthy

C. being overweight and being lazy can feed into each other

D. laziness is the main cause of weight problems

5.Which of the following is Not Right according to the passage?

A. Eating junk food can make us fat.

B. Researchers got different results after repeated the tests to fat rats.

C. For a long time, we’ve believed that people become fat because they are lazy.

D. If you constantly feel tired or study too hard, you need to pay attention to your diet.
