pierre is a 25-year-old penguin at the california academy of

sciences. due to his old age, he was going bald, which made

him feel too cold to swim in the pool. therefore, biologists at

the academy had a wet suit created for this penguin to help

him get back in the swimming pool.

unlike marine mammals, which have a layer of blubber to keep

them warm, penguins depend on their waterproof feathers.

without them, pierre was unwilling to jump into the swimming

pool and ended up trembling on the side of the pool while his

19 peers played in the water.

“he was cold; he would shake,” said pam schaller, a senior

biologist. schaller first tried a heat lamp to keep pierre warm.

then she got another idea: if wet suits keep humans warm in

the cold pacific, why not make one for pierre?

schalle

r designed the suit, which covered pierre’s body and

had small openings for his flippers.

“i would walk behind him and look at where there were any

gaps, and cut and refit and cut and refit until it looked like it

was extremely suitable,” she said. one co

ncern was that the

other penguins would reject pierre in his new suit, but in fact,

they accepted his new look. he swam freely and got along with

others well, although he was the only penguin with a black

stomach.

schaller couldn’t say for sure whether th

e wet suit allowed

pierre to recover his fine feathers, but “certainly we were able

to keep him comfortable during a period of time that would

have been very difficult for him to stay comfortable”. pierre will

take off his suit after his new feathers grow back. 1. pierre felt

too cold to swim in the pool because of.

a. not having a layer of blubber

b. having few feathers due to old age

c. having no wet suit

d. others penguins rejecting him 2. the idea of making a wet

suit for pierre came from .

a. total invention

b. the use of wet suit on humans

c. the use of heat lamp

d. waterproof feathers 3. schaller followed pierre in order to

see.

a. whether other penguins would reject him

b. if anywhere of wet suit needed to be cut and refit

c. if the wet suit kept warm

d. whether the wet suit would keep the feathers from

recovering

4. what does the underlined word in the second paragraph

mean?

a. feeling scared.b. staying alone.

c. shaking with cold.d. keeping warm. 5. the best title of the

passage is .

a. wet suit for an old penguin

b. old penguin getting bald

c. unwilling to swim

d. strange look of pierre

the african elephant, the largest land animal remaining on the

earth, is of great importance to african ecosystem(

生态系统

).

unlike other animals, the african elephant is to a great extent

the builder of its environment. as a big plan-teater, it largely

shapes the forest-and- savanna(

大草原

) surroundings in which

it lives, therefore setting the terms of existence for millions of

other animals that live

in its habitat. it is the elephant’s great

desire for food that makes it a disturber of the environment

and an important builder of its habitat. in its continuous search

for the 300 pounds of plants it must have every day, it kills

small trees and underbushes, and pulls branches off big trees.

this results in numerous open spaces in both deep tropical

forests and in the woodlands that cover part of the african

savannas(

热带草原

). in these open spaces are numerous plants

in various stages of growth that attract a variety of other plant-

eaters.

take the rain forests for example. in their natural state, the

spreading branches overhead shut out sunlight and prevent

the growth of plants on the forest floor. by pulling down trees

and eating plants, elephants make open spaces, allowing new

plants to grow on the forest floor. in such situations, the

forests become suitable for large hoofed plant-eaters to move

around and for small plant-eaters to get their food as well.

what worries scientists now is that the african elephant has

become an endangered species. if the elephant disappears,

scientists say, many other animals will also disappear from

vast areas of forest and savanna, greatly changing and

worsening the whole ecosystem.

6. what is the passage mainly about?

a. disappearance of african elephants.

b. forests and savannas as habitats for african elephants.

c. the effect of african elephants’search for food.

d. the eating habit of african elephants.

7. what does the underlined phrase “setting the terms” most

probably mean?

a. fixing the time.b. worsening the state.

c. improving the quality.d. deciding the conditions.

8. what do we know about the open spaces in the passage?

a. they result from the destruction of rain forests.

b. they provide food mainly for african elephants.

c. they are home to many endangered animals.

d. they are attractive to plant-eating animals of different kinds.

9. according to the passage, which of the following statements

is true?

a. the african elephant is the largest animal on the earth.

b. african elephants have 300 pounds of plants every day,

including small trees and underbushes.

c. the african elephant is in a way the builder of the

environment like other land animals.

d. if the african elephant disappears, the whole ecosystem

won’t be affected. 10. the passage is developed mainly by.

a. showing the effect and then explaining the causes

b. pointing out similarities and differences

c. describing the changes in space order

d. giving examples
