part 1
A great many cities are experiencing difficulties which are nothing new in the history of cities, except in their scale. Some cities have lost their original purpose and have not found new one. And any large or rich city is __1__going to attract poor immigrants, who flood in, filling with hopes of __2__prosperity which are then often disappointing. There are backward towns on the edge of Bombay or Brasilia, just as though there were on the edge of __3__seventeenth-century London or early nineteenth-century Paris. This is new is __4__the scale. Descriptions written by eighteenth-century travelers of the poor of Mexico City, and the enormous contrasts that was to be found there, are very __5__dissimilar to descriptions of Mexico City today—the poor can still be numbered __6__in millions.The whole monstrous growth rests on economic prosperity, but behind it lies __7__two myths; the myth of the city as a promised land, that attracts immigrants __8__from rural poverty and brings it flooding into city centers, and the myth of the __9__country as a Garden of Eden, which, a few generations late, sends them flood __10__-ing out again to the suburbs.
答案：
1 在new one前加a.这里one指代上下文中的可数名词purpose，因此该词前要有限定词。
2 将filling改为filled.在这里，非谓语动词fill与句子的whopoor immigrants之间是逻辑动宾关系，因此要使用过去分词来表示被动意义。
3 去掉though.
4 将this改为what.根据句子结构，我们可以看出这里需要一个关系代词，它既能引导主语从句，同时也可以在从句中作主语，这个关系代词就是what。如：What I like in a good author is not what he says，but what he whispers。
5 将was改为were.that引导定语从句，其先行词是descriptions…and the enormous contrasts,因此谓语动词be要用复数。
6 将dissimilar 改为 similar.这里要表示的是“共同，相似”之处。
7将lies 改为lie.behind it lie two myths 是个倒装句，主语为two myths，可见谓语动词要使用复数。
8 将that改为which.这里是一个非限制性定语从句，因此不可用that，而要用which。
9 将it改为them.复数名词immigrants的代词，所以要用复数形式。
10 将late改为later

答案与解析
1. 答案：insurances — insurers
试题分析：本题为名词误用 。
详细解答：文中指的是健康保险公司insurer ，而非抽象意义的保险insurance。
2. 答案：and — or
试题分析：本题为连词误用。
详细解答：文中的obese和overweight是两个表示体重超标的形容词，前者表示“过分肥胖的有病态的”，后者表示“超重的”，程度轻些，两种状态只能选其一，故用or。
3. 答案：More — Other
试题分析：本题为逻辑错误 。
详细解答：根据句子的意思：除医院提供的一些减肥的'项目之外，几乎没有其他可供选择的途径，所以选用“除……之外”other than，而不是“比……多”more than。
4. 答案：∧the — to
试题分析：本题为缺词错误 。
详细解答：contribute是一个不及物动词，与介词to搭配使用，表示“有助于，促成，导致 ……”。
5. 答案：∧help — that或help — helping
试题分析：本题为从句误用 。
详细解答：关系代词that在句中作限定性定语从句的主语，不能省略，否则句子不完整。或者也可以使用help 的非谓语动词形式，作为补充说明。
6. 答案：the — /
试题分析：本题为冠词误用 。
详细解答：句中的new approaches没有特指哪些新方法，上文也没有提到过，因此是泛指，不需要用定冠词 。
7. 答案：for — on
试题分析：本题为介词误用 。
详细解答：test sth. on sb. 是固定搭配，表示在某人身上做试验 。
8. 答案：lose — losing
试题分析：本题为非谓语动词误用 。
详细解答：have a difficult time doing sth. 表示在……方面经历了一段艰难时期，是固定搭配。
9. 答案：maybe — may be
试题分析：本题为副词误用 。
详细解答：本句缺少谓语动词，应该使用情态动词may，而非副词maybe，否则句子不完整。
10. 答案：gain — lose
试题分析：本题为逻辑错误 。
详细解答：本文的主旨是要帮助肥胖人士减肥lose pounds，从而使身体更加健康，而非增加体重gain pounds，与本意不符。
