With a good shopping position and the right amount(數(shù)量) of money, any educated person ought to be able to make a living out of a bookshop. It is not a difficult trade to learn and the large chain-stores can never force the small booksellers out of existence as they have done to the corner shop. But the hours of work are very long—I was only doing a part-time job, but my boss put in a seventy-hour week, besides regular journeys out of shopping hours to buy books.

The real reason why I should not like to be back in the book trade for life, however, is that while I was in it I lost my love of books. A bookseller cannot always tell the truth about his books, and that gives him a dislike for them. There was a time when I really did love books--loved the sight and smell and feel of them--if they were fifty or more years old, that is. Nothing pleased me quite so much as to buy a bargain lot of them on sale for several pounds. There is a peculiar flavour(獨(dú)特的味道) about the unexpected books you pick up in that kind of collection: little-known eighteenth-century poets, or out-of-date geography books. For occasional(偶爾的) reading--in your bath, for example, or late at night when you are too tired to go to bed--there is nothing as good as a very old picture story-book.

But as soon as I went to work in the bookshop I stopped buying books. Seen in a mass, five or ten thousand at a time, books were dull and even a little tiresome. Nowadays I do buy one occasionally, but only if it is a book that I want to read and can’t borrow, and I never buy rubbish.

Millions of aircraft take off around the world every year. The skies they fly in seem limitless--miles of empty space. But, with the number of flights increasing each year, this emptiness no longer exists. Researchers in the world of aviation(航空) are worried about the increasing pressure on pilots and ground controllers. And increasing collisions, occurring at or near an airport, have called attention to the need for more aids(輔助設(shè)備) to aviation control.

People who travel the skies are not certain about air safety. A great deal of money is spent on new and bigger aircraft and airports to deal with the vast increase in passengers travelling by air. Only a small percentage of this money is spent on navigation(導(dǎo)航) and other aids. Actually, suitable electronic equipment has long existed, and many companies market safety aids designed to make it safer for aircraft to take off, fly any distance, and land, whatever the weather. Yet, there are two problems to be solved. The first is to get governments, airlines and airport officials to agree to basic levels of safety aids. The second problem is to find a way of meeting these basic requirements.

But no matter how well the equipment works, operators of the equipment still play an important role. Communications between pilots and ground controllers are extremely important to air safety. It is worth pointing out that the mishearing or misunderstanding of instructions in English, and the use of another language, in an international conversation, have led to two recent aircraft accidents. A new type of instrument(儀器) called FLIGHTWATCH would help pilots prevent airport collisions. It would be particularly helpful near airports.

68. The increasing number of flights leads to the fact that ______.

A. flying is no longer limited in the sky

B. there is no empty space for aids to aviation control

C. piloting and controlling planes is getting more difficult

D. the pressure on the ground becomes greater

69. There is uncertainty about air safety because ______.

A. planes become bigger for the increasing number of passengers

B. money spent on electronic equipment is far from enough

C. suitable electronic equipment hasn’t been invented yet

D. it is dangerous for planes to take off or land

70. The underlined word “collisions probably means______.

A. accidents in which two planes hit each other

B. misunderstandings between pilots and ground controllers

C. quarrels among passengers

D. breakdowns of new types of instrument

71. It can be inferred from the passage that ______.

A. governments and officials have paid great attention to air safely

B. there should be more companies to sell new safety aids

C. English should be used in an international conversation

D. understanding between pilots and ground controllers should be improved
