College libraries are designed primarily for research and study．To explain its use, let us choose a research topic and follow the step-by-step procedure of looking up the material for the paper．

Suppose your assignment is to write a paper on a novel called “The Sun Also Rises” by American writer Hemingway．The first step is to go to the main catalog．Many small drawers on the large wooden cabinets are lined up in alphabetical（字母的） order．Each of the drawers contains hundreds of alphabetical ordered cards．These cards are printed references to all material available in the library．Title cards are cataloged （为…编目录） by the first word of the book title, leaving out the articles like “a”, “an” and “the”．And then you get the cards for the books you need．On the upper left corner of each card is the call number．This is the numerical code that shows where the book is located in the library．The library has open and closed stacks．If your book is on the open stacks, you can go to the open-stack room, and according to the call number find it out by yourself．There are only about 30,000 books on open stacks, while most of the 800,000 books in our library are kept in closed stacks, which are accessible only to teachers and graduate students．

For undergraduates like you, borrowing books from the closed stacks have to be done with the help of our librarian．In that case, you must fill out a call slip（纸条） for the book, showing the call number, author and title．You can get call slips on tables near the catalog cabinets．You show your call slip together with your library card to a librarian at the information desk．He or she will help you find the book out in the closed stacks．

What is the main purpose of this text?

A．To present readers a brief introduction to a college library．

B．To guide readers how to find books needed in a college library．

C．To tell readers how to fill out a call slip in a college library．

D．To show readers where to find books in a college library．

Microwaves may be great at warming up food, but what about warming people?

Using microwaves to directly heat owners of a room would save much of the energy wasted by heating walls and furniture. And despite popular ideas about microwaves, this technique would be safe, according to Charles R. Burlier of the Microwave Research Center in Marlborough, New Hampshire. Low-power microwaves only penetrate (贯穿) the skin (low-power microwave penetration in a ham is about 0.2 inches, for example) and with no negative effects.

To test this idea, Buffler subjected himself to microwaves in a special room using a standard 500-watt, 2459 MHz magnetron (磁控管). He found that a person will start to feel warmth at about 20 kilowatts per square centimeter (mw. / sq. cm. ) ; a satisfactory feeling of warmth occurs between 35 and 50 mw. / sq. cm. By comparison, a person standing in noonday summer sun feels the amount of 85 mw. / sq. cm. And a frozen meat pie in your microwave oven receives about 1000 mw. / sq. cm.

In houses of the future, each room could be provided with its own magnetron, says Buffler. When you stepped into the living room, for example, a motion detector (运动感应器)would turn on the magnetron, filling the room with low-power microwaves. In the same way that a microwave oven heats up a hamburger, but not the plate it’s on, you would feel warmth from the microwaves without changing the temperature of your coffee table. (You could, however, make your favorite easy chair even more comfortable by treating it with a radiation-absorbing chemical.)

While it might be some time before homeowners are comfortable enough with the idea to set up whole-body microwave heaters in houses, Buffler says microwaves may attract livestock(家畜) farmers. Lambs that are born outdoors in winter, for example, are frequently lost to cold. Microwaves could warm the lambs safely and quickly.

Which of the following can tell the main idea of the passage?

A. A new heating system.

B. A new microwave oven.

C. A popular technique.

D. The magnetron.

According to Paragraph 2, which of the following does not describe the characteristics of a microwave heater?

A. It directly heats people in a room.

B. It heats walls and furniture in a room.

C. It is safe.

D. It saves energy．

The test conducted by Buffler shows that when a person feels comfortable warmth, he receives about ________________.

A. 20 mw. / sq. cm. B. 40 mw. / sq. cm.

C. 60 mw. / sq. cm. D. 85 mw. / sq. cm.

According to Paragraph 4, which of the following fills the room with low-power microwaves?

A. The magnetron.

B. The motion detector.

C. The microwave oven.

D. The radiation-absorbing chemical.

Which of the following statements about microwave heaters would Buffler most probably agree with?

A. Microwave heaters will soon be widely used by homeowners.

B. Microwave heaters sometimes make people feel uncomfortable.

C. Perhaps microwave heaters will be first used by livestock farmers, who wish to protect their lambs in winter.

D. Microwave heaters cannot be accepted by the public because they are somewhat unsafe.

At the beginning of this century, medical scientists made an interesting discovery; we are built not just of flesh and blood but also of time. They were able to show that we all have "a body clock" 36 us, which controls the rise and fall of our body energies, 37 us different from one day to the next.

The idea of "a body clock" should not be too 38 since the lives of most living things are controlled by the 24 hour night-and-day cycle. We feel 39 and fall asleep at night and become 40 and energetic during the day. If the 24 hour-cycle is disturbed, most people experience unpleasant 41 . For example, people who are not 42 to working at night can find that 43 of sleep causes them to 44 badly at work. 45 the daily cycle of sleeping and waking, we also have other cycles which last longer than one day. Most of us would 46 that we feel good on some days and not so good on others ; sometimes our ideas seem to flow and at other times, they 47 do not exist.
