　　英語專八改錯練習題

　　One important outcome of the work on the expression of genes in developing embryos is sure to be knowledge that can help preventing birth defects. Just as promising (26) is the possibility of unraveling the complicated writing (27) of the brain. A mechanic gets valuable insight how an (28) automobile works by rebuilding car engines; similarly, neuroscientists can learn how the brain functions from (29) the way it is put together. The next step pursuing the (30) goal is to find out how the blueprint genes, the home box genes, control the expression of other genes that create the valves and piston of the working cerebral engine. The protein encoded by the latter genes could change the (31) stickiness of the cell surface, the shape of the cell or its metabolism to create the characteristic peculiar to, say, neurons or neural-crest cell. Surface proteins may be the (32) mechanism, whereby similar programmed cells stick together to form specific structures; they might also sense (33)the local environment to help the cell decide what is to do.

　　Clarifying those mechanisms will engage the best talents in (34) embryology and molecular biology for some times to come. (35) What is perhaps the most intriguing question of all is if the brain is powerful enough to solve the puzzle of its own creation.

　　參考答案：

　　1.preventing 改為prevent

　　plicated改為complexion

　　2.sight后加into

　　3.neuroscientist改為a neuroscientist

　　4.pursuing后加in

　　ter改為latter

　　5.similar改為similarly

　　6.去掉is

　　7.times改為time

　　8.if改為whether

　　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 fromone 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 whalehunting 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

　　1. 將which改為that。先行詞由最高修飾時定語從句的關(guān)系代詞只能用that。

　　2. 在thought 后面加of，或者將thought 改為regarded�！皌hink of A as B”，指“把A看作B”，為固定搭配。

　　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后加to�！皉efer 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 后加for。這句話實際的結(jié)構(gòu)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后加them。capture，slaughter，exploit都是及物動詞，后面必須加賓語。

　　7. 去掉but。前面已有“even though”，后面就不應(yīng)該再用but。

　　8 .將since改為from�！�100 years from now”指“從現(xiàn)在起100年后”since 只能用于完成時。

　　9. 在blame前加to。“be to blame for sth ”指“對某事應(yīng)負責任”，為固定搭配。

　　10. 在always前加has。這個定語從句強調(diào)對現(xiàn)在的影響，很明顯應(yīng)該用完成時，不能用過去式。

　　改錯題出現(xiàn)的錯誤經(jīng)常包括：語法;詞匯;語篇

　　1. 語法包括英語的時態(tài)，語態(tài)，倒裝句，虛擬語氣，主，謂，賓在數(shù)，格，人稱上的一致。

　　2 .詞匯方面，短文改錯在用詞上的錯誤主要集中在以下幾個方面：名次單復數(shù)，可數(shù)名詞和不可數(shù)名詞的差異，形容詞與副詞，連詞與介詞的誤用，同義詞的混淆等。

　　3. 語篇的改錯旨在測試做題者在具體語境上下文中使用語法和詞匯的能力。從邏輯的意義上看，句與句之間的關(guān)系可以分為順序，并列，時間，空間，層遞，對比，轉(zhuǎn)折，解釋，因果，過渡，推論等。最好的做法是先通讀全文，結(jié)合上下文的邏輯關(guān)系回答問題。

　　英語專八改錯練習及答案3

　　Psychologically there are two dangers to be guarded against in old age. One of these is due absorption in the past. It does not __1__work to live in memories, in regrets for the good old days, or in __2__sadness about friends who are dead. One's thoughts must be directed to the future, and to things which there is something to be done. __3__This is not always easy; one's own past is a gradually increasing weight. It is easy to think for oneself that ont's emotions __4__

　　are used to be more vivid than they are, and one's mind more __5__keen. If this is true it should be forgotten, and if it is forgotten it will probably not be true.

　　The other thing to be avoided is clinging to youth in hope of __6__sucking vigour from its vitality. When your children are growing up __7__they want to live their own lives, and if you continue to be as interested in them as you were when they were young, you are likely to become a burden to them, except they are unusually callous. I do not __8__mean that one should be without interest in them, but one's interest should be contemplatory and, if possible, philanthropic, but not __9__unduly emotional. Animals become indifferent to their young as soon as their young can look after themselves, but human beings, owing to the length of infantry, find this difficult. __10__

　　答案及解析:

　　1.due-undue

　　如果是due absoption，就沒有必要說two dangers to guarded against，所以這里犯了語義顛倒的錯誤。

　　2.work-do

　　work在這里用得不好，應(yīng)該為do，表示“能……”，work往往表示“行不行得通”，如：It does not work to employ two people. We need at least 5.

　　3.which-about

　　這里缺少了介詞about，使先行詞things 和something to be done無法連接。

　　4.for-to

　　to think for oneself表示“為自己著想”，這這里顯然不是這個意思，應(yīng)改為to oneself 表示“自己想……”，類似于to say to oneself。

　　5.are(used)-/

　　be used to 表示“習慣于……”，而這里的意思是“過去曾經(jīng)……”，所以應(yīng)改為used to do。

　　6.hope-the
