Ⅳ.阅读理解

When the natural climate changes due to global warming,it can

surely affect seals.The majority of them live in the Antarctic

region so as the ice is melting,their natural habitat can be

seriously affected.These changes don’t take place overnight.They

can be the result of many years of additional temperatures in the

area.The seals then have to find ways to adapt.

Seals depend on the cool air currents to bring plenty of food

for them.When the temperatures get higher there is less and less

food and the seal population starts to shrink.Mothers aren’t healthy enough to feed their babies.Many of them end up being 第4页 共12页 abandoned as the mothers have to leave to find their own source of

food.

The fact that their desire to produce young can be changed by

the warmer temperatures is frightening too.It is also believed that

the warmer temperatures can allow different diseases and viruses

to attack the seals.This is a huge concern as they can rapidly wipe

out huge numbers of seals out there.

However,these changes in climate and temperature aren’t all

bad for other species of seals.Scientists have found that those

living in warmer climates are producing more young due to the

changes.Research also shows that the females are moving further to

find food and water.When they are out of the reach of the governing

males,they are more willing to accept the moves of other males in

the group.

This is good news too because it means that there will be more

selection in the gene pool(基因库)for future generations.It can

help the seals as a species adapt to the change in their natural

environment more easily. 第5页 共12页 The climate change problem for seals is directly linked to

humans.When we take action to change what we let out into the

environment,we will make positive changes for the seals.However,it

is going to take a very long time to reverse(彻底改变) the effects

of what has already been done.

1.What does the author regard climate changes for seals as?

A.A double-edged sword.

B.An unavoidable disaster for eirror of evolution.

D.A requirement for more choice in the gene pool.

2.What will happen to the seals in warmer climates?

A.Their number will be on the increase.

B.The female seals will be in the lead.

C.Their genes will change a great deal.

D.The females will keep away from the males.

3.Which of the following can be the best title for the teportance

of Protecting Seals

B.Seals’ Adaptation to Climate Change

C.How Climate Change Affects Seals 第6页 共12页 D.Why Are Seals Becoming Less and Less
