Tokyo is one of those places that you can love and hate at the same time.

　　In Tokyo there are always too many people in the places where I want to be. Of course there are too many cars. The Japanese drive very fast, but in Tokyo they often spend a long time in traffic jams(拥挤).Tokyo is not different from London, Paris and New York in that. It is different when one wants to walk.

　　At certain times of the day there are a lot of people on foot in London’s Oxford Street. But the streets near the Ginza in Tokyo always have a lot of people on foot, and sometimes it is really difficult to walk. People are very polite; there are just too many of them.

　　The worst time to be in the street is at 11:30 at night. That is when the night-clubs are closing and everybody wants to go home. There are 35 000 night-clubs in Tokyo, and you do not often see one that is empty.

　　During the day, most people travel to and from work by train. Tokyo people buy six million train tickets every day. At most stations, trains arrive every two or three minutes but at certain hours there do not seem to be enough trains. Although they are usually crowded, Japanese trains are very good. They always leave and arrive on time. On a London train you would see everybody reading a newspaper. In Tokyo trains everybody in a seat seems to be asleep, whether his journey is long or short.

　　In Tokyo, I stood outside the station for five minutes. Three fire-engines(消防车) race past on the way to one of the many fires that Tokyo has every day .Tokyo has so many surprises that none of them can really surprise me now.

Adults are often surprised by how well they remember something they learned as children but have never practised in the meantime. A man who has not had an opportunity to go swimming for years can ___21___ swim as well as ever when he gets back in the water. He can get on a bicycle after several decades and still    22    away. A mother who has not    23   the words for years can teach her daughter the poem that begins "Twinkle, twinkle, little star" or recite the story of Cinderella or Snow White.

　　One explanation is the    24     of over learning, which can be stated as following: Once we have learned something, additional learning increases the    25    of time we will remember it.

　　In childhood, we usually continue to practise such skills as swimming, bicycle riding long after we have learned them. We continue to listen to and    26    ourselves of poems such as "Twinkle, twinkle, little star" and childhood tales such as Cinderella or Snow White. We not only learn but  __27   .

　　The law of over learning explains why cramming (突击学习) for an examination, though it may result in a(an)    28     grade, is not a    29    way to learn a school course. By cramming, a student may learn the subject well enough to get by on the examination, but he is likely soon to forget almost everything he learned. A little over learning,    30   , is usually a good investment toward the future.
