Ⅱ.阅读理解(共5小题；每小题2分，满分10分)

Let us take a look at the exact harvest of the sea.The first thing that comes into the mind is the fish.Fishing in the sea is a major industry of the world and maritime countries and their people depend on fish for food.There are major fishing grounds of the world，notably the North Sea and the Sea of Japan.

Besides fish，the whale is hunted for its flesh and blubber as well as its bones.Whale hunting is a dangerous job because the whale is not a fish in the real sense and it can destroy a boat if it strikes.A whole novel Moby Dick has been dedicated to whale hunting.

The floor of the sea has not been exploited.There is a belief that the deep floors of the sea must be rich in minerals.When the minerals on the land is exhausted，perhaps man may turn to the sea bed for resources.There is，of course，mineral oil found in some places in the sea bed.Already some countries have taken up the idea and have started prospecting for oil in the sea.

If the harvest of the sea is understood in a wider sense，water transport then can also be the bloodstream of the world's commerce.Wide arteries(干道)of shipping lines have liners loaded with the world's goods.Till the invention of the airplane the ship was the only link connecting countries divided by the seas.

Another important item of harvest is the energy that could be produced by using the tidal waves.There are countries where these tidal waves may bring harm.But they could be used to produce power.This possibility has not been ruled out and there are attempts ready to get this source.

A．the sea bed will be opened up further

B．many countries will fight for the sea

C．the sea bed should be protected well

解析　推理判断题。第三段主要说明，海底矿物资源丰富，在陆地矿物资源开采完之后，人们或许会转而开采海底矿物资源，即将来海底矿物资源将得到进一步开发。

答案　A

19．How many sea harvests does the passage describe?

Ⅲ.信息匹配(共5小题；每小题2分，满分10分)

阅读下列应用文及相关信息，并按照要求匹配信息。

首先请阅读下列一些书的内容简介：

A．I Am a Pencil

Sam Swope's job was teaching third­graders writing in New York City.His students

were from 21 countries，speaking 11 languages，with different backgrounds.But there

were a few things they had in common，family troubles，a money struggle，and

poetry.Every single student，with the help of this creative teacher，came forth with

awesome writing.Swope leaves the reader with the inspiring conviction(坚定的信仰) that

deep within each of us lives a poet.

B．Between a Rock and a Hard Place

Aron Ralston,28，went hiking in a remote Utah canyon without telling anyone.An

unexpected catastrophe struck.With enough supplies only for a day，Ralston knew his

situation was full of danger.Sure enough，after five days he was in a fight against

death.That was when he carried out a courageous plan—using a pocket knife to cut off his

trapped arm.His amazing survival story rests at a place among the classics of the genre.

C．Our Brother's Keeper

Author Jedwin Smith spent 30 years trying to repress(抑制) all memories of his

brother，Jeff，who was killed in Vietnam.But in Our Brother's Keeper he tells what

happens when the Internet brings him into contact with several his brother's old Marine

friends，including the guy who held Jeff in his arms as he died.First via e­mail，and then in

person，Smith gets to know these men.

D．The All Americans

With his graduation from West Point，Henry Romanek sailed toward Omaha Beach

on the eve of D­day.It was June 1944，and he was about to face the bloodiest battle of his

life.Just yesterday，it seemed，he was a standout soldier on the Army team.Today，he was

a leader of youngsters in battle，fighting，quite literally，for his country and the future of

the free world.In this book，Lars Anderson retraces Romanek's life and that of three other

soldiers.

E．Copies in Seconds

With the push of a button，anyone can make copies of almost anything—unlike the o

ld days，when papers had to be rewritten long­hand，carbon­copied out of fussy

mimeograph machines(油印机)．In Copies in Seconds，David Owen showed how a shy

engineer named Chester Carlson perfected his xerography machine(静电复印机) and

shopped it around until finally hooking up with the Haloid Corporation.That partnership

led to the Xerox copier and changed the face of work forever.

F．State of Grace

Back in the late 1950s and early 1960s，the Lynvets was just a football team in a New

York City neighborhood.But to most of its members—the author，Robert Timberg，

included—the team was their only experience of a happy family，their only chance to rise

above lousy everyday circumstances，their only shot at being heroes.The friendships these

men formed sustained them throughout their lives.
