B跨学科保护海洋的重要性(2024.福建中考改编)
Though oceans cover about 71 per cent of the earth's surface,
there's still a lot we don't know about them.Only about 20 per cent
of the seafloor has been mapped,and the remaining 80 per cent is
still a secret to us.Some scientists even think that 91 per cent of sea
animals have yet to be discovered.
So why do we know so little about the deep sea?Well,getting
to those depths is very difficult and requires high technology that
simply didn't come into being for most of human history.The first
navigable submarine(可驾驶的潜水艇)， for example ， was built in
1620,and it couldn't go more than five metres below the surface.In
fact,for a long time many scientists didn't even think that there
could be any life at depths greater than 550 metres and didn't see
much need to explore(探索)the deep sea.However,this changed
in 1862 when life was discovered as far down as 945 metres below
sea level with the help of a digging machine. Ten years later,
around 4,700 species(物种)unknown before from the ocean floor
were discovered.
Since then,high technology has been developed to help explore
the deep sea,including satellites.But why is deep−sea exploration
still so difficult?Well,at greater depths it is freezing(极冷的),
everything is completely dark,and the pressure can be over 1,000
times greater than that on the surface.
Though we have the difficulties, it's important that we
understand the seas.They help control the earth's temperature and
produce half of the oxygen(O 2)in the air.They can also provide us
with information about climate change. Our future depends on
learning more about our oceans,and it is possible for us to really
understand what is ongoing below the surface.

答案： B【文章大意】本文介绍了深海探索的现状、困难及其重要性。
1.D [解析]推理判断题。根据“Though oceans cover about 71 per cent of the earth's surface，there's still a lot we don't know about them...”可知，列举的数字表明，尽管海洋覆盖地球的约71％，但是我们对海洋仍然知之甚少。故选D。
2.A [解析]推理判断题。根据“In fact，for a long time many scientists didn't even think that there could be any life at depths greater than 550 metres and didn't see much need to explore(探索) the deep sea.”和“Since then，high technology has been developed to help explore the deep sea，including satellites.”可知，探索深海需要高科技的帮助。故选A。
3.B [解析]代词指代题。根据“Though we have the difficulties，it's important that we understand the seas.”可知，虽然我们有困难，但了解海洋是很重要的。此处they指代上文的the seas。故选B。
4.C [解析]标题归纳题。本文主要介绍了探索海洋的重要性。根据“Since then，high technology has been developed to help explore the deep sea，including satellites. But why is deep-sea exploration still so difficult?”可知，文章主要是介绍深海探索的现状，并不是过去与未来。故选C。
