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.According to the passage, which of the following can NOT be typed into the same category?
A.cloud | B.sheep | C.trees | D.goose |

Sports can help you keep fit and get in touch with nature.However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment.
Some sports are resource-hungry.Golf, as you may know, eats up not only large areas of countryside, but also tons of water.Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses (球场) in good condition.This causes major environmental effects.For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas.
There are many environment-friendly sports.Power walking is one of them that you could take up today.You don’t need any special equipment except a good pair of shoes; and you don’t have to worry about resources and your purse.Simple and free, power walking can also keep you fit.If you walk regularly, it will be good for your heart and bones.Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control.
Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials.But the final goal should be “green gyms”.They are better replacements for traditional health clubs and modern sports centers.Members of green gyms play sports outdoors, in the countryside or other open spaces.There is no special requirement for you to start your membership.And best of all, it’s free.The author thinks the golf is resource-hungry because of the following EXCEPT that ________.
A.Golf wastes large areas of countryside |
B.Golf runs out of much water |
C.Golf is bad for people’s health |
D.Keeping golf court in good condition needs too much energy |
According to the passage, which of the following is an environment-friendly sport?
A.hiking in the hills | B.swimming in the pool |

A.it improves our health | B.it is an outdoor sport |
C.it is recommended by experts | D.it uses fewer resources |
The passage is developed mainly by ________.
A.examples and explanation | B.comparison and persuasion |

Honey from the African forest is not only a kind of natural sugar, it is also delicious. Most people, and many animals, like eating it. However, the only way for them to get that honey is to find a wild bees’ nest and take the honey from it. Often, these nests are high up in trees, and it is difficult to find them. In parts of Africa, though, people and animals looking for honey have a strange and unexpected helper — a little bird called a honey guide.
The honey guide does not actually like honey, but it does like the wax in the beehives (蜂房). The little bird cannot reach this wax(蜡), which is deep inside the bees’ nest. So, when it finds a suitable nest, it looks for someone to help it. The honey guide gives a loud cry that attracts the attention of both passing animals and people. Once it has their attention, it flies through the forest, waiting from time to time for the curious animal or person as it leads them to the nest. When they finally arrive at the nest, the follower reaches in to get at the delicious honey as the bird patiently waits and watches. Some of the honey, and the wax, always falls to the ground, and this is when the honey guide takes its share.
Scientists do not know why the honey guide likes eating the wax, but it is very determined in its efforts to get it. The birds seem to be able to smell wax from a long distance away. They will quickly arrive whenever a beekeeper is taking honey from his beehives, and will even enter churches when beeswax candles are being lighted.Why is it difficult to find a wild bees' nest?
A.It's small in size. | B.It's buried in the soil. |
C.It's covered with wax. | D.It's hidden in trees. |
What do the words "the follower" in Paragraph 2 refer to?
A.A bee. | B.A bird. |
C.A honey searcher. | D.A beekeeper. |
The honey guide is special in the way ________.
A.it gets its food | B.it goes to church |
C.it sings in the forest | D.it reaches into bees’ nests |
What can be the best title for the text?
A.Wild Bees | B.Wax and Honey |
C.Honey-Lover's Helper | D.Beekeeping in Africa |
One day, when I was working as a psychologist(心理学家) in England, a young boy showed up in my office. It was David. He kept walking up and down restlessly, his face pale, and his hands shaking slightly. His head teacher had introduced him to me before. “This boy has lost his family,” he wrote. “He is understandably very sad and refuses to talk to others, and I’m very worried about him. Can you help?”
I looked at David and showed him to a chair. How could I help him? There are problems which psychology doesn’t have the answer to, and which no words can describe. Sometimes the best thing one can do is to listen openly and silently. And I would do in this way.
The first two times we met, David didn’t say a word. He sat there, only looking up to look at the children’s drawings on the wall behind me. I suggested we play a game of chess. He nodded. After that he played chess with me every Wednesday afternoon—in complete silence and without looking at me. It’s not easy to cheat in chess, but I admit I made sure David won once or twice.
Usually, he arrived earlier than agreed, took the chess board and pieces from the shelf and began setting them up before I even got a chance to sit down. It seemed as if he enjoyed my company. But why did he never look at me?
“Perhaps he simply needs someone to share his pain with,” I thought. “Perhaps he senses that I respect his suffering.” Some months later, when we were playing chess, he looked up at me suddenly.
“It’s your turn,” he said.
After that day, David started talking. He got friends in school and joined a bicycle club. He wrote to me a few times, about his biking with some friends, and about his plan to get into university. Now he had really started to live his own life.
Maybe I gave David something. But I also learned that one—without any words—can reach out to another person. All it takes is a hug, a shoulder to cry on, a friendly touch, and an ear that listens.When he first met the author, David_________.
A.felt a little excited | B.walked stubbornly |
C.looked a little nervous | D.showed up with his teacher |
As a psychologist, the author __________.
A.was uncertain about psychology | B.was ready to listen to David |

David enjoyed being with the author because he____________.
A.needed to share pain with the author |
B.wanted to ask the author for advice |
C.liked the children’s drawing in the office |
D.beat the author many times in the chess game |

A.He recovered after months of treatment. |
B.He liked biking before he lost his family. |
C.He went into university soon after starting to talk. |
D.He got friends in school before he met the author. |
What made David change?
A.His teacher’s help. |
B.His exchange of letters with the author. |

The Healthy Habits Survey shows that only about one third of American seniors(年长者) have correct habits. Here are some findings and expert advice.
1.How many times did you brush your teeth yesterday?
·Finding:About 33% of seniors brush their teeth only once a day.
·Step:Remove the 300 kinds of bacteria in your mouth each morning with a battery-operated toothbrush. Brush gently for 2 minutes, at least twice a day.

·Finding:Seniors, on average, bathe fewer than 3 days a week. And nearly 30% wash their hands only 4 times a day—half of the number that doctors advise.
·Step:We touch our faces around 3,000 times a day-often inviting germs(病菌)to enter our mouth, nose, and eyes. Use toilet paper to avoid touching the door handle. And, most important, wash your hands often with hot running water and soap for 20 seconds.
3. How often do you think about fighting germs?
·Finding:Seniors are not fighting germs as well as they should.

You may think that sailing is a difficult sport, but it is really not hard to learn it.You do not need to be strong.But you need to be quick.And you need to understand a few basic rules about the wind.
First, you must ask yourself, “Where is the wind coming from? Is it coming from ahead or behind or from the side?” You must think about this all the time on the boat.The wind direction tells you what to do with the sail.
Let's start with the wind blowing from behind.This means the wind and the boat are going in the same direction.Then you must always keep the sail outside the boat.It should be at a 90° angle (角度) to the boat.Then it will catch the wind best.
If the wind is blowing from the side, it is blowing across the boat.In this case, you must keep the sail half way outside the boat.It should be at a 45° angle to the boat.It needs to be out far enough to catch the wind, but it shouldn't flap (摆动).It shouldn't look like a flag on a flagpole.If it is flapping, it is probably out too far, and the boat will slow down.
Sailing against the wind is not possible.If you try, the sail will flap and the boat will stop.You may want to go in that direction.It is possible, but you can't go in a straight line.You must go first in one direction and then in another.This is called tacking.When you are tacking, you must always keep the sail inside the boat.What should you consider first while sailing?
A.Sailors' strength. | B.Wave levels. |
C.Size of sails. | D.Wind directions. |
What does the word “It” underlined in Paragraph 4 refer to?
A.The boat. | B.The sail. |
C.The wind. | D.The angle. |
What do you have to do when sailing against the wind?
A.Move in a straight line. | B.Allow the sail to flap. |
C.Lower the sail. | D.Tack the boat. |
Where can you probably find the text?
A.In a popular magazine. | B.In a tourist guidebook. |
C.In a physics textbook. | D.In an official report. |
