AMany views are held as to whether or not sharks will attack man.Some people believe that a shark will attack man only when he is near the shark in the water.Others take the position that sharks never attack man.The facts show that the truth is between these two positions.There are thirty-two kinds of sharks,and only three are dangerous to man.These are the hammerhead shark,the tiger shark,and the white shark.All sharks are easily frightened and are much more afraid of man than man afraid of them.They have a keen (敏锐的) sense of smell even from a place that is a fairly long way away.The smell of blood excites them,and then they may attack human beings.If such an attack does take place,however,it is done blindly because the shark happens to be excited by the smell of blood.This is very different from the manner in which a lion or a tiger will attack its victim (受害者) in the woods.The one acts without thinking while the other acts with the greatest care.1Which is the best title for this passage?A.Sharks and Other AnimalsB.Sharks’ Attack on ManC.Why does Blood Excite SharksD.Sharks,the Most Dangerous of All the Fishes,故答案为B项。

2The main difference between the manners in which a lion attacks its victim and a shark attacks a man is .A.in the speed of the attackB.that the lion is careful with the attack,but the shark acts without thinkingC.that the lion is more cruel than the sharkD.that the shark’s attack is less sudden“Thisisverydifferentfromthemannerinwhichalionoratigerwillattackitsvictim(受害者)inthewoods.Theoneactswithoutthi nkingwhiletheotheractswiththegreatestcare.”可知鲨鱼不假思索就攻击人,而狮子、老虎攻击人时非常小心。

3Why does a shark attack a man blindly?A.Because the shark is easy to be frightened.B.Because the shark has a keen sense of smell.C.Because the shark has just been excited by the smell of blood.D.Because the shark always protects itself by attacking the others.“Ifsuchanattackdoestakeplace,however,itisdoneblindlybecausethesharkhappenstobee xcitedbythesmellofblood.”可知血腥味吸引鲨鱼。

BWhat do you know about the sea?We know that it looks very pretty when the sun is shining on it.We also know that it can be very rough when there is a strong wind.What other things do we know about it?The first thing to remember is that the sea is very big.When you look at the map of the world you will find there is more water than land.The sea covers three quarters of the world.The sea is also very deep in some places.It is not deep everywhere.Some parts of the sea are very shallow.But in some places the depth of the sea is very great.There is one spot,near Japan,where the sea is nearly 11 kilometers deep!The highest mountain in the world is about 9 kilometers high.If that mountain were put into the sea at that place,there would be 2 kilometers of water above it!What a deep place!If you have swum in the sea,you know that it is salty.You can taste the salty.Rivers,which flow into the sea,carry salt from the land into the sea.Some parts of the sea are more salty than other parts.There is one sea,called the Dead Sea,which is very salty.It is so salty that swimmers cannot sink!Fish cannot live in the Dead Sea!In most parts of the sea,there are plenty of fishes and plants.Some live near the top of the sea,and others live deep down.There are also millions of tiny living things that float in the sea.These floating things are so small that it is hard to see them.Many fish live by eating these.The sea can be very cold.Divers,who go deep down in the sea,know this.On the top the water may be warm.When the diver goes downwards,the sea becomes colder and colder.Another thing happens.When the diver goes deeper,the water above presses down on him.It squeezes(挤压) him.Then the diver has to wear clothes made of metal.But he cannot go very deep.Some people who wanted to go very deep used a very strong diving ship!They went down to the deepest part of the sea in it.They went down to a depth of eleven kilometers!4When does the sea look beautiful?A.When it is calm.B.When the weather is fine.C.When there is a strong wind.D.When there is a storm.看出B项正确。

“Theweatherisfine.”和“Thesunisshining.”意思相近。

5Why does the author cite (引用) the sea somewhere near Japan?A.To show that the sea in some place is very deep.B.To show that the sea in some place is very rough.C.To show that its depth is 9 kilometers greater than the height of the highest mountain.D.To show that its depth is 11 kilometers greater than the height of the highest mountain.“Butinsomeplacesthedepthoftheseaisverygreat.”“Whatadeepplace!”看出是强调海洋的深度。
