We all know that everyone becomes a little more forgetful as they get older, but men’s minds decline more than women’s, according to the results of a worldwide survey.

General differences seem to be natural in male and female brains: Men are better at maintaining and dealing with mental images (useful in mathematical reasoning and spatial skills), while women tend to excel be good at recalling information from their brain’s files. Many studies have looked for a connection between sex and the amount of mental decline people experience as they age, but the results have been mixed.

Some studies found more age-related decline in men than in women, while others saw the opposite or even no relationship at all between sex and mental decline.

Those results could be improper because the studies involved older people, and women live longer than men: The men tested are the survivors, “so they’re the ones that may not have shown such cognitive(认知的) decline,” said study team leader Elizabeth of the University of Warwick in England.

Scientists surveyed completed four tasks that tested sex-related cognitive skills: matching an object to its rotated form, matching lines shown from the same angle, typing as many words in a particular category as possible in the given time, e.g. “object usually colored gray”, and recalling the location of objects in a line drawing. The first two were tasks at which men are usually good; the latter are typically dominated by women. Within each age group studied, men and women performed better in their separate categories on average. And though performance declined with age for both genders, women showed obviously less decline than men overall.

1.According to the passage, which of the following can NOT be typed into the same category?

A．cloud            B．sheep            C．trees             D．goose

B．Women stand out at remembering people’s names.

3.One important factor that affects the correctness of the results is that ________.

A．women live longer than men

B．people surveyed are all old

C．the old men tested may not have shown such cognitive decline

D．people taking part in this test came from all over the world

4.The author aims to tell us that _________.

Sure, we've all heard that we should get more sleep. The realities of life often make it become "we should get more sleep later." 　 1. The result is that you wake up the next day feeling like a role of The Walking Dead. Here are four ways you can adjust your biology in order to pay less for staying up.

● Move around.

Exercising before bed is a sure way to keep awake. That's why you shouldn't do it when you want to go to sleep, and it is also why hitting the gym, or even some fast push-ups can tell your body that it's not time for bed.　 Being physically exhausted isn't fun when you are trying to stay up late. 　 2.

● Eat more protein.

Few people think about the fact that the brain and body use a lot more energy when we're awake. If you are pulling an all-nighter, you're going to need a lot more food than you are used to eating. 　 3. To stay awake, plan to eat larger meals than normal and to eat them more frequently.

● Drink the right stuff.

It's tempting (诱人) to switch to sugary caffeine drinks like Red Bull, but the sugar will lead to a crash. Instead, if you want to use caffeine, drink early in the evening so it'll wear off by the time you want to sleep.

4. Don't make it worse by drinking sugar.

● 5.

Turn the lights down at night because bright lights keep you awake. For three or four hours after you're exposed to bright white light, your body won't make melatonin, a must for deep sleep. You will sleep better if you turn the lights a little bit down.

A. Turn the lights off.

B. Avoid bright lights.

C. Just do enough to get energetic.

D. And your body can never bear something like that.

E. Your brain can use up to 25 percent of your total calories.

F. When you stay up late, your blood sugar becomes abnormal.

G. There is either more work to be done, or more fun to be had, or both.

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.
