　　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.

　　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. 将which改为that。先行词由最高修饰时定语从句的关系代词只能用that。

　　2. 在thought 后面加of，或者将thought 改为regarded。“think of A as B”，指“把A看作B”，为固定搭配。

　　3. 去掉he。这句话的.主语是“to hunt a whale”，“to hunt a whale was high adventure”。中间的“when…”只是插入的状语从句。

　　4. 在referred后加to。“refer to A as B”只“把A称作B”，这句话的意思是“古人把鲸称作大鱼”。

　　5. 在felt 后加for。这句话实际的结构是“feel a sense of wonder for whales”指“对鲸怀有惊奇的感觉”，for引出对象。

　　6. 在exploit后加them。capture，slaughter，exploit都是及物动词，后面必须加宾语。

　　7. 去掉but。前面已有“even though”，后面就不应该再用but。

　　8 .将since改为from。“100 years from now”指“从现在起100年后”since 只能用于完成时。

　　9. 在blame前加to。“be to blame for sth ”指“对某事应负责任”，为固定搭配。

　　10. 在always前加has。这个定语从句强调对现在的影响，很明显应该用完成时，不能用过去式。

　　改错题出现的错误经常包括：语法;词汇;语篇

　　1. 语法包括英语的时态，语态，倒装句，虚拟语气，主，谓，宾在数，格，人称上的一致。

　　2 .词汇方面，短文改错在用词上的错误主要集中在以下几个方面：名次单复数，可数名词和不可数名词的差异，形容词与副词，连词与介词的误用，同义词的混淆等。

　　3. 语篇的改错旨在测试做题者在具体语境上下文中使用语法和词汇的能力。从逻辑的意义上看，句与句之间的关系可以分为顺序，并列，时间，空间，层递，对比，转折，解释，因果，过渡，推论等。最好的做法是先通读全文，结合上下文的逻辑关系回答问题。

　　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，就没有必要说two dangers to guarded against，所以这里犯了语义颠倒的错误。

　　2.work-do

　　work在这里用得不好，应该为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

　　这里缺少了介词about，使先行词things 和something to be done无法连接。

　　4.for-to

　　to think for oneself表示“为自己着想”，这这里显然不是这个意思，应改为to oneself 表示“自己想……”，类似于to say to oneself。

　　5.are(used)-/

　　be used to 表示“习惯于……”，而这里的意思是“过去曾经……”，所以应改为used to do。

　　6.hope-the
