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 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.這裏one指代上下文中的可數名詞purpose，因此該詞前要有限定詞。
2 將filling改爲filled.在這裏，非謂語動詞fill與句子的who(poor immigrants)之間是邏輯動賓關係，因此要使用過去分詞來表示被動意義。
3 去掉though.
4 將this改爲what.根據句子結構，我們可以看出這裏需要一個關係代詞，它既能引導主語從句，同時也可以在從句中作主語，這個關係代詞就是what。如：What I like in a good author is not what he says，but what he whispers。
5 將was改爲引導定語從句，其先行詞是descriptions…and the enormous contrasts,因此謂語動詞be要用複數。
6 將dissimilar 改爲 similar.這裏要表示的是“共同，相似”之處。
7將lies 改爲nd it lie two myths 是個倒裝句，主語爲two myths，可見謂語動詞要使用複數。
8 將that改爲which.這裏是一個非限制性定語從句，因此不可用that，而要用which。
9 將it改爲them.複數名詞immigrants的代詞，所以要用複數形式。
10 將late改爲later

答案與解析
1. 答案：insurances — insurers
試題分析：本題爲名詞誤用 。
詳細解答：文中指的是健康保險公司insurer ，而非抽象意義的保險insurance。
2. 答案：and — or
試題分析：本題爲連詞誤用。
詳細解答：文中的obese和overweight是兩個表示體重超標的形容詞，前者表示“過分肥胖的(有病態的)”，後者表示“超重的”，程度輕些，兩種狀態只能選其一，故用or。
3. 答案：More — Other
試題分析：本題爲邏輯錯誤 。
詳細解答：根據句子的意思：除醫院提供的一些減肥的'項目之外，幾乎沒有其他可供選擇的途徑，所以選用“除……之外”other than，而不是“比……多”more than。
4. 答案：∧the — to
試題分析：本題爲缺詞錯誤 。
詳細解答：contribute是一個不及物動詞，與介詞to搭配使用，表示“有助於，促成，導致 ……”。
5. 答案：∧help — that或help — helping
試題分析：本題爲從句誤用 。
詳細解答：關係代詞that在句中作限定性定語從句的主語，不能省略，否則句子不完整。或者也可以使用help 的非謂語動詞形式，作爲補充說明。
6. 答案：the — /
試題分析：本題爲冠詞誤用 。
詳細解答：句中的new approaches沒有特指哪些新方法，上文也沒有提到過，因此是泛指，不需要用定冠詞 。
7. 答案：for — on
試題分析：本題爲介詞誤用 。
詳細解答：test sth. on sb. 是固定搭配，表示在某人身上做試驗 。
8. 答案：lose — losing
試題分析：本題爲非謂語動詞誤用 。
詳細解答：have a difficult time doing sth. 表示在……方面經歷了一段艱難時期，是固定搭配。
9. 答案：maybe — may be
試題分析：本題爲副詞誤用 。
詳細解答：本句缺少謂語動詞，應該使用情態動詞may，而非副詞maybe，否則句子不完整。
10. 答案：gain — lose
試題分析：本題爲邏輯錯誤 。
詳細解答：本文的主旨是要幫助肥胖人士減肥lose pounds，從而使身體更加健康，而非增加體重gain pounds，與本意不符。
