[单项选择] Passage 1
All animals must rest, but do they
really sleep as we know it The answer to this question seems obvious. If an
animal regularly stops its activities and stays quiet and unmoving——if it looks
as though it is sleeping——then why not simply assume that it is in fact
sleeping But how can observers be sure that an animal is sleeping
They can watch the animal and notice whether its eyes are open or closed,
whether it is active or lying quietly, and whether it responds to light or
sound. These factors are important clues, but they often are not enough. Horses
and cows, for example, rarely close their eyes, and fish and snakes cannot close
them. Yet this does not necessarily mean that they do not sleep. Have you ever
seen a cat dozing with an eye partly open Even humans have occasionally been
observed to sleep with one or both eyes par

impossible to escape from some idle or inquisitive chatter-box, or from somebody
who wants something for nothing. If you have a telephone in your own house, you

out, or when you are in your bath. Are you strong-minded enough to ignore it, to
say to yourself, "Ah, well it will all be the same in a hundred year’s time"
You are not. You think there may be some important news or message for you. I
can assure you that if a message is really important it will reach you sooner or
later. Have you never rushed dripping from the bath, or chewing from the table,
or dazed from th
A. Harmful thing.

[单项选择] Passage Two
Many Americans harbor a grossly
distorted and exaggerated view of most of the risks surrounding food. Fergus
Clydesdale, head of the department of food science and nutrition at the
University of Massachusetts-Amherst, says bluntly that if the dangers from
bacterially contaminated chicken were as great as some people believe, "the
streets would be littered with people lying here and there."
Though the public increasingly demands no-risk food, there is no such
thing. Bruce Ames, chairman of the biochemistry department at the University of
California, Berkeley, points out that up to 10% of a plant’s weight is made up
of natural pesticide (杀虫剂). Says he, "Since plants do not have jaws or teeth to
protect themselves, they employ chemical warfare." And many naturally produced
chemicals, though occurring in tiny amounts, prove in labor
A. Immediate measures must be taken to improve food production and processing.
