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.

As we know, many teen celebrities(名人) feel and think that having a slimmer figure can do great good to them. But, does size really matter? Are teenage fans trying hard to become like their celebrity idols(偶像)? Do celebrities really have the power to influence people, especially teenagers?

For the longest time, many parents blame teen idols for influencing the way their kids act. Have you noticed how teens idolize the celebrities these days? Even, their personal affairs are being followed by kids these days. Take for example the case of Lindsay Lohan of Mary Kate Ashley. They are definitely famous teen stars.

Teens watching TV shows and reading magazines are easily pulled into the dieting and harmful eating habits because the media have some ways to pull these acts. They use thin models and celebrities to endorse(做广告宣传) products or to star in an up-and –coming shows or movies. With fierce competition, celebrities are forced to eat less and do extreme exercise routines to get the roles or offers that come their way.

Living in today’s time and generation is a bit disturbing to a lot of parents. Media, especially as well as the celebrities, have a very powerful influence to drive teenagers to good or bad. It’s good that we can control ourselves to avoid bad things from happening. If not, parents should really be aware and guide their teens to determine what’s in ad what’s out.

“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.

You want a smart phone， but just how smart do you want it？ How about one that can read your mind？ Well， that phone may well be on its way...

Justin Rattner， chief researcher at Intel， says that technology has developed to the point that “context-aware computing (情景感知计算)”， an idea that’s been around for twenty years， is becoming more of a reality.

That could lead to a phone that acts as a mind reader in your pocket. But rather than simply collect secrets about you， the device could do things with that information， such as predict what you might do next and make suggestions.

Rattner gave a few examples during his speech at Intel’s developer conference in San Francisco recently.

Among them is a software that Intel worked on with Fodor’s Travel， a traveling website. It learns what types of foods you like to eat and what types of places you like to visit， based on searches you type into the phone or places you searched using GPS (全球定位系统). The software makes similar recommendations when you visit a new city.

Tech companies are already working to predict what people want. Search engine Google， movie-rental service Netflix， and online radio service Pandora try to guess what people want even before they know they want it.

Putting those types of functions together with the other information that phones collect about people could pave the way for even more helpful mobile phones， Rattner said.

A challenge is training computers to look at data from “hard sensors (传感器)” (which measure place， movement， temperature and the like) and combining those findings with data from “soft sensors” (such as calendar appointments and Web browsing history).

For example， your phone could tell that you have just left school and seem to be on your way home—a location it might know from your address book. It could then tell you the best route around traffic.

Rattner added that researchers are even making steps toward the final goal—a computer understanding of thoughts.
