The great whales are among the most fascinating creatures which __1__ have ever lived on the earth, and one of them, the blue whale, is the largest. People in ancient times thought whales as fearsome __2__ monsters of the ocean depths. So to hunt a whale, when one occasionally swam toward shore, he was high adventure. People __3__ found the adventure was rewarding, too, for the oil and meat from one whale alone could heat and feed a village for a whole winter.
Whales resemble huge fish. They were referred by the ancients as __4__ “great fish,” and any whale beaching along the coasts of England was designated “the King‟s fish” because it automatically belonged to the Crown.
Ever since those early times, human have felt whales a sense of __5__ wonder mixed with an intense desire to capture, slaughter, and exploit. Now the slaughter has reached alarming proportions. __6__ Even though some species are protected by the regulations of the International Whaling Commission and theoretically all whale hunting is regulated, but the earth‟s stock of whales is still being __7__ depleted. In fact, some scientists worry that 100 years since now __8__ there may be no whales left. If this happens, mankind will be blame for removing from the earth forever a remarkable and __9__ awe-inspiring creature that always fed man‟s imagination and __10__ made the world a more exciting place.
參考答案及解析:
1、將which改爲that。先行詞由最高修飾時定語從句的關係代詞只能用that。
2. 在thought 後面加of，或者將thought 改爲regarded。“think of A as B”，指“把A看作B”，爲固定搭配。
3. 去掉he。這句話的`主語是“to hunt a whale”，“to hunt a whale was high adventure”。中間的“when„”只是插入的狀語從句。
4. 在referred後加to。“refer to A as B”只“把A稱作B”，這句話的意思是“古人把鯨稱作大魚”。
5. 在felt 後加for。這句話實際的結構是“feel a sense of wonder for whales”指“對鯨懷有驚奇的感覺”，for引出對象。
6. 在exploit後加them。capture，slaughter，exploit都是及物動詞，後面必須加賓語。
7. 去掉but。前面已有“even though”，後面就不應該再用but。
8 .將since改爲from。“100 years from now”指“從現在起100年後”since 只能用於完成時。
9. 在blame前加to。“be to blame for sth ”指“對某事應負責任”，爲固定搭配。
10. 在always前加has。這個定語從句強調對現在的影響，很明顯應該用完成時，不能用過去式。
task 2What is a black hole? Well, it is difficult to answer the question,as the terms we would normally use to describe a scientific phenomenon __1__ are adequate here. Astronomers and scientists think that a black hole is __2__ a region of space which matter has fallen and from which nothing can __3__ escape—not even light. But we can‟t see a black hole. A black hole __4__ exerts a strong gravitational pull and yet it has no matter. It is only space—or thus we think. How can this happen? __5__
The theory is that some stars explode when their density increases to a particular point; they “collapse” and sometimes a supernova occurs. The collapse of a star may produce a “White Dwarf” of a “neutronstar”—a star which matter is so dense that if continually shrinks by the force of __6___ its own gravity. But if the star is very large, this process of shrinking maybe so intense that a black hole results in. Imagine the earth reduced to the __7__ size of a marble, but still having the same masses and a stronger __8__gravitational pull, and you have some ideas of the force of a black hole. __9__ And no matter near the black hole is sucked in. __10__
參考答案及解析:
supernova 名詞，[天]超新星
1. 將as 改爲since或者because。在表示原因的連接詞中，只有as引導的原因狀語從句不能位於主句之後，只能位於句首。
2 .將adequate 改爲inadequate，或者在are後加not。從邏輯上分析，因爲我們擁有的科學術語“不充足”，所以才無法回答這個問題，所以用否定形式。
3. 在which 前加into。這是一個定語從句，意思是“黑洞是太空中物質可以掉進去的地方”，所以
定語從句應該爲“into which matter has fallen”。
4. 將but 改爲 so。 上文已提到“連光都無法從黑洞中逃出”，所以我們根本無法看到黑洞。這裏應該是因果關係，而不是轉折關係。
5 .將thus改爲so。這句話的意思是“那只是空間—或者我們認爲它只是空間”。so做 think 的賓語，thus 只能做連詞，不能做賓語。
6. 將which 改爲whose。這個定語從句的意思是“它是一顆星，其密度非常大，由於自身的引力，它在不斷地收縮”。matter 屬於star，所以關係代詞應該用whose。
7 .去掉in。result爲不及物動詞，意爲“形成了”，而“result in sth。”意爲“導致某結果”。
8. 將masses 改爲mass。mass 可指“大量的物質”，而“the masses”特指“勞動羣衆”，用在此處不妥。
9 .將ideas 改爲idea。“idea”在表達“印象”時，爲不可數名詞，不可以用複數。
10. 將no改爲any。分析便知，任何在黑洞附近的東西都會被吸進去。
