【答案】
A.
1) The cheetah.
2) 170 km/h.
3) More than
100 km/h.
4) Because most animals run
on four legs.
5) Because we have
machines.

【原文】
The fastest
animal on land
is the cheetah. It can run at a speed of about 100 kilometres an
hour. The fastest bird in the world can
fly at 170 km/h, and the fastest fish can swim at
more than
100 km/h.
Human
beings are not very fast. The fastest man in the
world can only run at about 40 km/h.
Many animals can run faster than this.
But most animals run on four legs. Four legs are
better than
two, aren’t they? Why do we
only have two legs?
Scientists
say that we are more intelligent than other
animals because we stand on two legs,
so we can
use
our
hands for
other
things.
We can
pick
things
up with
them.
We can
use
tools.
Human beings have used
tools for millions of years. That is why our
brains have developed. That
is why we
have become the most intelligent animals in the
world.
In
the
past
few
years,
we
have
made
all
kinds
of
machines.
We
have
made
cars,
ships,
aeroplanes
and spacecraft. In these machines we can travel
faster than any animal
—
by
land, by
sea, or by air. We can
even go to the moon. No other animal has ever done
that!

【答案】
A.
1)
Climate, lack of food and aliens from outer space
might be responsible for their extinction.
2) No.
B.
B: might have gotten, killed them off
A: may have run out of food
B: could have been destroyed by aliens
【原文】
A: Y
ou know,
we’re studying din
osaurs in science class.
It’s really interesting.
B: Oh, yeah? Hey,
have you learned why the dinosaurs disappeared?
A: Well, no one knows for sure.
B: I thought it had something to do
with the climate. The temperature might have
gotten cooler
and killed them off.
A:
Y
eah, that’s one theory. Another idea is that they may have run out of food.
B:
Uh-
huh.
And you know, there’s even a theory that they could have been destroyed by aliens
from
outer space.
A: That sounds crazy to
me!
T
ask 4
【答案】
1) The mayfly.
A
few hours.
2) They just do two
things: finding a mate and producing young.
3) We could judge by its growth rings.
4) It was kept for 152 years.
【原文】
For the shortest
life, the first prize must go to the mayfly, which
typically lives only a matter
of a few
hours after it emerges from its shell. Few
mayflies live to see the sun rise again. These
creatures
devote
their whole
lives
to
a
single
desperate
mission:
finding
a
mate
and
producing
young. They
don’t even have functional mouths and
stomachs. They simply have no time to eat. In
fact they have no time for
anything else.
The
record-holder
for
the
longest
life
may
be
the
Arctic clam,
one
of which
lived
quietly
underwater for 220
years. However it did not have any birth
certificate to prove this. One could
only judge by its growth rings.
If you insist on better documentation,
the oldest animal ever was probably a tortoise
that died
in
1918.
It
had
been
captured
already
full-grown
in
1766,
nine
years
before
the
American
Revolution began and it died 152 years
later as World War I came to a close.

【原文】
Every
year
about
17
million
animals
are
used
in
Laboratory
experiments.
But
in
many
countries
today,
a
difficult
question
is
being
asked:
Do we
have
the
right
to
use
animals
in
this
way?
People
who
are
for
using
animals
in
research
argue
that
the
use
of
animals
in
medical
research
has
many
practical
benefits.
Animal
research
has
enabled
researchers
to
develop
treatments
for
many
diseases,
such
as
heart
disease
and
depression.
It
would
not
have
been
possible to develop vaccines for
diseases like smallpox and polio without animal
research. Every
drug anyone takes today
was tried first on animals.
Future
medical research is dependent on the use of
animals. Which is more important: the life
of a rat or that of a three-year-old
child?
Medical
research
is
also
an
excellent
way
of
using
unwanted
animals.
Last
year,
over
12
million animals
had to be killed in animal shelters because no one
wanted them as pets.
However those who are against it point
out that the fact that humans benefit cannot be
used to
justify using animals in
research any more than it can be used to justify
experimenting on other
humans. Animals
suffer a lot during these experiments. They are
forced to live in small cages, and
they
may be unable to move.
Much of the
research that is carried out is unnecessary
anyway.
Animals have the same rights as
humans do
—
to be able to move freely and not to have pain
or
fear
forced
on
them.
Researchers
must
find
other
ways
of
doing
their
research,
using
cell
culture and computer
modeling. There should be no animals in research
laboratories at all.
