Not too many decades ago it seemed “obvious” both to the general public and to sociologists that modern society has changed people’s natural relations, loosed their responsibilities __1__ to kins (親戚) and neighbors, and substituted in their place __2__ for superficial relationships with passing acquaintances. __3__ However, in recent years a growing body of research has revealed that the “obvious” is not true. It seems that if you are a city resident, you typically know a smaller proportion of your neighbors than you if you are a resident of a smaller community. __4__ But, for the most part, this fact has a few significant consequences. __5__ It does not necessarily follow that if you know few of your neighbors you will know no one else.
Even in very large cities, people maintain close social ties within small, private social worlds. Indeed, the number and quality of meaningful relationship do not differ between more and less urban __6__ people. Small-town residents are more involved with kin than do big __7__ city residents. Yet city dwellers compensate by developing friendships with people who share similar interests and activities. Urbanism may produce a different style of life, but the quality of life does not differ between town and city. Or are residents of large communities __8__ any likely to display psychological symptoms of stress or alienation __9__ than are residents of smaller communities. However, city dwellers do worry more about crime, and this leads them to a distrust for strangers. __10__
答案：
ed改為loosened。儘管loose也可作及物動詞，但它的含義是“鬆開，解開，發射，釋放”等具象的含義，在這裡語義不符，而loosen則往往與tie、control、discipline、restriction這樣的詞連用表示抽象含義。
改為kin。kin是集體名詞，用單數表達複數概念，相當於relatives，另外，kin作主語的話，謂語動詞也應用複數形式。（記得上次的machinery麼，也是這個改法）
3.去掉for。在substitute A for B 的用法中，for引導的是被代替項而不是代替項。
4.(than you)^ do。兩個比較分句如果謂語部分相同則可以省略後一個分句的謂語，或者用do來代替。
5.去掉a
tionship改為relationships。Relationship既可以作可數名詞又可以作不可數名詞。由於前面有 the number of 這樣分詞修飾，這裡relationship應該當作可數名詞。
改為are。兩個比較分句的謂語動詞應該同是be involved，如果將後一個比較分句裡的動詞部分省略，保留下來的'也應該是be動詞，而不是do。
改為nor。前句話是否定結尾的，本句也應是否定的含義。
ly改為likelier。由於有than出現，這裡是一個比較句。
改為of。distrust 後往往跟of，不跟for，如：a distrust of the media。 It does not necessarily follow that if you know few of your neighbors you will know no one else.這話初看有點彆扭。follow有這麼個意思，必然是…的後果，必然有…後果，所以這裡大概意思是：不認識什麼鄰居並不意味著你也不認識其他人。例如：He is good，it does not follow that he is wise。
