It has been discovered that after the age of sixteen, the number of our brain cells begins to decrease at a speed of several million a year. They simply die off. In certain types of activity, the human brain is at its highest point in the early twenties, when it has collected enough information to be able to use the vast number of cells freely in the most effective way. Pure mathematics is one of the fields in which this happens, and we know that Albert Einstein made all his world-shaking discoveries between the age of about 20 and 25, and spent the rest of his life tidying them up and arranging them.
But in certain other types of activity (of which being an author is perhaps one), experience is more important than sharpness of brain, and there one usually finds that a person reaches his or her peak much later in life.
Besides sharpness of brain and experience, here is another thing that is very important, and that is wisdom. One can have a very quick, inventive brain and plenty of experience, but if one uses these foolishly, one harms both oneself and others. Wisdom does not always come with age ——there are plenty of foolish middle-aged people about ——but the average person tends to learn wisdom as he gets older, usually by making painful of embarrassing mistakes. Leaning to be wise is basically learning what is not possible ； and what is possible but so difficult that it is not worth all the trouble one has to go through to get there. Mostly, it is learning about human nature ； how real people behave and react, as against how one would like them to behave and react. One can read and hear lot of idealistic stuff about how to make the world a better place, which would be found if it was based on an accurate observation of human nature, but which is basically a waste of time because it is not.

There are at least 3 ,000 miles of waterways in Britain. On these canals and rivers, there are over 30,000 'houseboats'—boats that people use as homes. Around 10 ,000 of them are located in London.
The earliest populations of Britain's 'boat people' have been living on the water since the canals were built during the industrial revolution. Since then, houseboat living has usually attracted people who prefer to live an alternative lifestyle. Houseboat communities are typically made up of people who are looking for a slower way of life and who want to be in touch with nature.
Living on the water sounds romantic, but it is also hard work. There are daily things that need to be done, like bringing fuel and water on board and dealing with 'waste' water from kitchen sink, shower and toilet. In winter, living on a boat can be very cold and there is always a feeling of damp. Of course, most boats are quite small inside, so you don't have much space, especially if you are a couple, family or a group of friends.
Despite these difficulties, the number of people living on Britain's waterways has increased by around 50 per cent over the past ten years. More and more families and young professionals are moving onto houseboats, not only because they like the idea of life on water.but also because it is much cheaper to buy or rent a boat than a flat or a house.
There is a great sense of community on the waterways ； many boat people say that their neighbours are always ready to help them, and houseboat neighbours often become friends for life. This is quite a different story from people who live in flats or houses and may hardly know the people next door at all.
1.What does the underlined word "alternative" in paragraph 2 probably mean?
A.Creative. B.Enjoyable.
C.Non — traditional. D.Primitive.
2.From the third paragraph, we know that it is to live on the boat.
A.inconvenient B.easy
C.boring D.unforgettable
3.Which of the following information is not given in the text?
A.There are lots of rivers and canals in Britain.
B.Many people live on houseboats in Wales.
C.Houseboat living become popular in the industrial revolution.
D.People who live on houseboats are usually very friendly with their neighbours.
4.Why do many people choose to live on the water? Because .
A.living on the water is romantic
B.living on the water is easy and natural
C.living on the water can avoid unfriendly neighbours
D.living on the water costs less than living on the land
