题目内容
4.Oceans cover nearly 75% of the earth's surface.(41)Based (base) on the amount of light received,the ocean can (42)be divided(divide) from its surface to its depth into three zones.Sunlit zone is the top layer,(43)which goes down about 600feet.There is enough light for photosynthesis(光合作用) (44)to occur(occur) here.Over 90% of all marine life lives in this zone.
Twilight zone begins at about 600feet under the water and extends to the (45)darkest(dark) part,beginning about 3,000feet down.There is little light and the water pressure increases here.As (46)a result,plants do not grow here and animals that live here use their bodies to attract light.
90% of the ocean is in the midnight zone.It is (47)entirely(entire) dark.The water pressure is extreme and the temperature is near freezing.The living things found here live close (48)to cracks in the Earth's crust (地壳) and rely on the bacteria that live near the crusts for food.
We are all aware (49)that living things in oceans have always been an important source of food.(50)However,overuse of the ocean by man has led to the decline in the population of some fish.
分析 本文主要介绍海洋的分层.即按照深度划分为三层:表层,中层和深层.
解答 41.Based 考查过去分词.the ocean与base之间是动宾关系,用过去分词短语作状语.
42.be divided 考查动词语态.the ocean与divide之间是动宾关系,用情态动词的被动语态.
43.which 考查定语从句.分析句子结构可知这是一个定语从句,先行词the top layer在从句中作主语,用关系代词which.
44.to occur 考查动词不定式.此处动词不定式作后置定语修饰photosynthesis.
45.darkest 考查形容词最高级.根据定冠词the放在形容词前,要用形容词最高级.
46.a 考查冠词.as a result意为"结果,因此",是固定搭配.
47.entirely 考查副词. dark是形容词,要用副词修饰.
48.to 考查固定搭配.close to意为"接近于; 在…的近旁",是固定搭配.
49.that 考查连词.此处是"be aware that+从句"用法,意为"知道…".
50.However 考查副词.however表示转折,尤其用于谈及一个既成事实时,表示转折,其意为"可是""仍然"等.可放在句首、句中或句末,通常用逗号与句子其他成分隔开.

They (20)B sitting in the living-room,the 10-year-old daughter,looking at the flowers outside the window.The father was just about to take his cup when the (21)C came,right there in the living room.Something was hopelessly broken.
It was the thermos,which had fallen to the floor.The girl looked (22)D her shoulder at once,startled (吓一跳),(23)A.It was (24)C.Neither of them had touched it,not even a little bit.The sound caused the host to rush back from the inner room.He looked at the (25)B floor and blurted out (脱 口而出),"It doesn't matter,it doesn't matter!"
The father started to say something.Then he muttered (嘀咕),"Sorry,I (26)A it and it fell."
"It doesn't matter,"the host said.
Later,when they left the house the daughter said,"Daddy,I saw your (27)Cin the windowpane (窗玻璃).You were sitting perfectly (28)B.Why did you say…?"
The father (29)C,"What then would you (30)D as the cause of its fall?"
"It fell by itself!Maybe the floor is uneven.It wasn't steady when Mr Li put it there."
"It won't (31)C,girl.It sounds more (32)C when I say I touched it.There are things people accept less the more you (33)A them.The truer your story is,the less true it sounds."
The daughter was (34)D in silence for a while.Then she said,"Can you explain it only this way?"
"Only this way,"the father laughed again."Since life is not perfect,sometimes we need to deal with it with a white (35)B.
