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

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 mine weeks old, which can be seen in the action of children ad 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.

London has become a cycle friendly zone after the launch of a new bike hire scheme.It has been designed to encourage more people to cycle in and around central London.

So how does it  work?First you have to sign up to the scheme to be sent a key.The key will unlock one of the bikes,which are kept at docking stations in  and around central London.You have to pay an access fee for the key and then you pay as you go,for he length of time you use the bike.

Transport for London, which runs the scheme,are hoping to have 6,000 bikes and 400 docking stations in place by the end of the year.The new hire system is hoping to ease congestion in London and is expected to generate up to 40,000 extra cycle trips a day into the city centre.London Mayor Boris Johnston launched the scheme and said London had been “filled with thousands of gleaming machines that will transform the look and feel of our streets and become as commonplace on our roads as black cabs and red buses”.

However,there  have been a few problems since the scheme was launched last Friday.On the first day some people found they couldn’t dock their bike  properly and their usage of the bike had not registered.Transport for London did admit they had been expecting a few “teething problems”and have said they wouldn’t charge for the first day as a“gesture of goodwill”.Some other people have criticized the lack of docking stations and locks for the bikes as well as the price it costs to hire the bicycles.

Despite the comments,the green-thinking London Mayor still seems very positive about things,saying,“My campaign for the capital to become the greatest big cycling city in the world has taken a gigantic pedal-powered push forwards.”
