Did you know that women’s brains are smaller than men’s? The average women’s brain weighs 10% less than men’s.Since research has shown that the bigger the brain, the cleverer the animal, men must be more intelligent(聪明的) than women.Right? Wrong.Men and women always score similarly on intelligence tests, despite the difference in brain size.Why? After years of study, researchers have concluded that it’s what’s inside that matters, not just the size of the brain.The brain consists of “grey matter” and “white matter”.While men have more of the latter, the amount of “thinking” brain is almost exactly the same in both sexes.
It has been suggested that smaller brain appears to work faster, perhaps because the two sides of the brain are better connected in women.This means that little girls tend to learn to speak earlier, and that women can understand sorts of information from different sources at the same time.When it comes to talking to the boss on the phone, cooking dinner and keeping an eye on the baby all at the same time, it’s women who come out on top every time.
There are other important differences between two sexes.As white matter is the key to spatial(空间的) tasks, men know better where things are in relation to other things.“A great footballer always knows where he is in relation to the other players, and he knows where to go,” says one researcher.That may explain one of life’s great mysteries: why men refuse to ask for directions…and women often need to!
The differences begin when fetuses(胎儿) are about nine weeks old, which can be seen in the action of children as young as one.A boy would try to climb a barrier (障碍物) before him or push it down while a girl would attract help from others.These brain differences also explain the fact that more men take up jobs that require good spatial skills, while more women speech skills.It may all go back to our ancestors(祖先), among whom women needed speech skills to take care of their babies and men needed spatial skills to hunt, according to one research.
If all this disappoints you, it shouldn’t.“The brain changes throughout our lives according to what we do with it.” says a biologist.

Every few years, two groups carry out a study of how many Americans wash their hands after using the toilet. These groups are the American Society for Microbiology and the American Cleaning Institute, formerly the Soap and Detergent Association.
There was good news in the latest study. Researchers found that eighty-five percent of adults washed their hands in public restrooms last month. That was the most since the studies began in 1996.
Researchers visited restrooms at a baseball park in Atlanta and a science museum and aquarium(水族馆) in Chicago. They also visited two train stations in New York City and a large farmers’ market in San Francisco. In all, they observed about six thousand adults, with females and males equal in number.
The researchers found that seventy-seven percent of men and ninety-three percent of women washed their hands. That was up from sixty-six percent of men and eighty-eight percent of women in the last study three years ago.
The lowest rate of hand washing among men was at Turner Field, home of the Atlanta Braves baseball team. Only sixty-five percent of men washed their hands, compared to all but two percent of women.
Chicago and San Francisco had the most hand washers—eighty-nine percent of adults. Atlanta followed at eighty-two percent. New York had the lowest rate, at seventy-nine percent of the adults observed at Grand Central Station and Penn Station.
The findings of the observational study conflicted(不一致) with the findings of a separate telephone survey of about one thousand people. Ninety-six percent of them said they always washed their hands after using public restrooms.
Almost nine out of ten also said they always washed after using the bathroom at home.
Hand washing can help prevent the spread of many different infections.
To clean your hands well, wet them first and rub in soap for at least twenty seconds, including between the fingers and under the nails. Then wash under running water. In a public restroom, if you dry your hands with a paper towel, you should also use the towel to shut off the water and open the door.
Hand washing is also important when preparing food and after changing a baby’s diaper(尿布). You should also wash if you cough or sneeze into your hands.According to the latest study, about ____ women washed their hands after using public bathroom.
A.1,980 | B.2,310 | C.2,640 | D.2,790 |

While I was on a trip to Papua New Guinea to take underwater photographs, I asked a local dive guide to help me find a pygmy sea horse(侏儒海马). I wanted to take a picture of it. These sea horses can be red or yellow-and-orange. The red pygmy sea horse lives on only one type of coral, a red sea fan that grows at depths below ninety feet.
This depth made the job even tougher. As the pressure on my body increased, I had to breathe harder, which used my air supply faster. So the deeper I dived, the shorter my time underwater.
I had a lot to do. First, I had to find the pygmy sea horse’s special type of fan .Then I had to look over the whole fan with my magnifying glass(放大镜) to see if a sea horse lived on it. If not, I had to find another fan—all the while keeping an eye on my oxygen supply. The second fan rewarded me with a find. The dive guide held the magnifying glass so I could have my first look at the tiny fish.
My next challenge was to focus my camera on such a small subject. The dive guide pointed at the tiny creature. I looked through the viewfinder(取景物) on my large underwater camera housing(相架), found the guide’s finger, and followed it to the sea horse.
It was hard to hold ourselves steady because both of us were floating in mid-water, but our system worked. I could hardly contain my excitement as I focused on the eyes of the cutest sea horse imaginable.What do we learn about the red pygmy sea horse?
A.It lives on red sea fans only. | B.It swims very quickly. |
C.It lives nine feet deep. | D.It usually floats in mid-water. |

When you leave home to go and live somewhere else, you naturally take your own personality and cultural ways with you. When you arrive in a new country with a different culture you can experience different kinds of feelings and reactions. For example, you may feel confused and nervous, and like to depend on others.
If you do experience these things, then you are probably experiencing culture shock. For example, coming to Australia from another country certainly gives you a chance to face many new things: the buildings look different, and the food is not what you are used to. You may not be able to speak with other people confidently.
Learning to function effectively in a new culture is not easy. Meanings in cross-cultural situations are often unclear. This can be stressful because you are not sure what others expect of you or what you can expect of them. In these situations it is natural to feel anxious and frustrated(挫折). If you recognize that these feelings are a normal part of the experience of living away from “home”, you may be able to deal with them more efficiently. Your sense of humor and openness will also help. As you gain greater understanding of the new culture, you can expect the stress to disappear.
Dealing with culture shock needs a special effort, but it is the most important to remember that you are not alone in your feelings of distress. Most people in their first weeks and months in a new country experience similar reactions.This passage mainly tells us _______.
A.How to adapt(适应) to a new environment | B.how to live in Australia happily |
C.how to study in a new environment | D.how to avoid being nervous |
Why do people have many kinds of feelings in a new country?
A.Because they are surprised at everything they see. |
B.Because buildings are very beautiful. |
C.Because culture shock does have a great effect on them. |

Which of the following is the most important thing in dealing with culture shock?
