If a child has good parents, heis fed, looked after and loved, what he may do, It is 11. _improbable that he will ever again in his life be givenso much without having to do anything in turn. In addition, 12. _life is always presenting new things to the childthingsthat have lost their interesting for older people because 13. _they are too well-known. A child finds pleasure in playingin the rain, or in the snow. JP+2His first visit to theseaside is a marvelous adventure. But a child has his pains:He is not so free to do as he wishes as he thinks old 14. _people do; he is continually being told not to do things,or being punished for that he has done wrong. 15. _His life is therefore not perfectly happy. 16. _When the young man starts to earn his own living, hebecomes free from the discipline of school and parents;but at the same time he is forced to accept responsibilities.He can not longer expect others to pay for his food, hisclothes, and his room, but has to work if he wants to livecomfortable.

Every normal person isexpert in the skill of pronouncing his own language, and 21. _few people are even moderately proficient at pronouncingforeign languages. Now there are many reasons about this, 22. _some obvious, some perhaps not so obvious. But I suggestthat the fundamental reason why people in general do notspeak foreign languages very better than they do is that 23. _they fail to grasp the true name of the problem of learningto pronounce, and consequently never set about tacklingit by the right way. Far too many people fail to realize 24. _that pronounce a foreign language is a skill, one that 25._needs careful training of a special kind, and one thatcannot be acquired by just leaving it to take care of himself. 26. _I think even teachers of language, while recognizing theimportance of a good accent, tend to neglect, in their practicalteaching, the branch of study concerning with speaking the 27. _language. So the first point I want to make is that Englishpronunciation must be taught; the teacher may be prepared to 28. _devote some of the lesson time to this, and by his wholeattitude to the subject he should get the student to feelthat here is a matter worth of receiving his close attention. 29. _So, there should be occasions where other , 30. _such as grammar or spelling, are allowed for the moment totake a secondary place. （4）People often dream of living in a perfect place where noone would be poor, and everyone would be considerable of 31. _everyone else.

These legends were no longer believed 37. _when the explorations of Americans began, but after Morestime they became common for there places 38. _Utopia, if is effected, would not suddenly make everything 39. _perfect because people are of nature imperfect. 40. _ 改错专项训练题参考答案（1）1. 去掉in。“多宽多厚”一般用“meter wide /thick”表示。2. 把from改成 in。result from 后接原因，而result in 后才接结果。3. 把extensively 改成extensive。extensive在这里做was的表语，故用形容词形式。4. 把live改成alive。alive, live都有“活的，活着”之义，但alive一般做表语或后置定语，live一般只做前置定语。Alive在本句中做主语的补语。5. 把close改成closure。the of 结构中间应该用名词。6. 把followed改following。following在此做伴随状语，如果用followed做并列谓语必须在此词前加and 。7. 把in改成on。表示具体的一天的早上，下午，晚上用介词on。一般用in。8. 把also改成and。also只是副词，不能连接两个谓语，而and是连词，可以起连词作用。9. 在gouged 的后面加 by，表被动，“被火山熔岩凿出一个大峡谷”。10. 去掉 north前的the。north在这里用作副词。（2）11.what改为whatever。whatever引导让步状语从句，相当于no matterwhat，意思是“无论什么”，“不管什么”，whatever在从句中作宾语。12.turn改为return。短语in turn表示“轮流地; 挨个, 依次; 反过来”，而在这里是指孩子对父母的回报。13.interesting改为interest。在形容词性物主代词their的后面应跟名词性成分。14.do改为 are。与前面的is相对应。15.that改为what。that引导的是定语从句，在本句中应该使用关系代词what，相当于the thing/ thingsthat。16.not改为no。固定搭配的副词短语“no longer”17.comfortable改为comfortably。修饰动词live应为副词而不是形容词。18.suffer改为go或become或be。或把hungry改为hunger。19.therefore改为however。此处的条件状语从句表示转折。20.making 改为 make。（3）21.andbut。and表示递进并列关系；but表示转折关系。根据上下文应用but。22. aboutfor。reason与介词for搭配，表示“的原因”。23. very bettervery much better。very不能修饰形容词的比较级，只能用much,far, verymuch, a lot, any, no, rather, a little, a bit修饰。24. byin。by the way：顺便说一下；in the right way：以正确的方式，又如：in your ownway：以自己的方式。25. pronouncepronouncing。在that 引导的宾语从句中主语是动名词短语pronouncing aforeign language,原形动词（这里为pronounce）不能作主语。26. himselfitself。one在本句中不是指人，所以其反身代词可用itself，而不用himself。27. concerningconcerned。be concerned with：关于，如：The book is chiefly concer
