Can animals be made to work for us
Some scientists think that one day animals may be trained to do a number of
simple jobs that are now done by human beings.
They point out
that at a circus, for example, we may see elephants, monkeys, dogs and other
animals doing quite skillful things. Perhaps you have seen them on the
television or in a film. If you watch closely, you may notice that the trainer
always gives the animal a piece of candy or a piece of fruit as a reward. The
scientists say that many different animals may be trained to do a number of
simple jobs if they know they will get a reward for doing them.
Of course, as we know, dogs can be used to guard a house, and soldiers in
both old and modem times have used geese to give warning by making a lot of
noise when a stranger or an enemy comes near. But it may be possible
A. Animals are very skillful at a circus.
B. They are big and strong.
C. Some animals are as clever as human beings.
D. Animals can be trained because they like to get something as a reward.
[单项选择] Passage Two
People can be addicted to different things — e.g.
alcohol, drugs, certain foods, or even television. People who have such addition
are compulsive, i.e. they have a very powerful psychological need that
they feel they must spend money. This compulsion, like most others, is
irrational — impossible to explain reasonably. For compulsive spenders who buy
on credit, charge accounts are even more exciting than money. In other words,
compulsive spenders feel that with credit, they can do anything. Their pleasure

discounts. Compulsive bargain hunters, however, often buy things they don’t need
just only because they a

D. to meet their basic needs
[单项选择]If phone calls and web pages can be beamed through the air to portable devices, then why not electrical power, too It is a question many consumers and device manufacturers have been asking themselves for some time. But to seasoned observers of the electronics industry, the promise of wireless recharging sounds depressingly familiar. In 2004 Splashpower, a British technology firm, was citing “very strong” interest from consumer-electronics firms for its wireless charging pad. Based on the principle of electromagnetic induction (EMI) that Faraday had discovered in the 19th century, the company’s “Splashpad” contained a coil that generated a magnetic field when a current flowed through it. When a mobile device containing a corresponding coil was brought near the pad, the process was reversed as the magnetic field generated a current in the second coil, charging the device’ s battery without the use of wires. Unfortunately, although Faraday’s principles of electromagnetic induction have st

C. To integrate consumer-electronics firms and chipmakers.
D. To promote a common standard for inductive wireless charging.
