【答案解析】

1. B. 因为collection (收藏品，收集物) 是可数名词，此处为单数，又不是特指，所以用不定冠词;books是名词复数表示种类，而非特指，所以不用冠词。又如：a fine collection of paintings精美的绘画收藏品。

2. B. word (话、话语) 是可数名词，without saying a word意为“没说一句话”;虽然silence (沉默)是不可数名词，但此处是特指前面提到的那种沉默，所以用the。

3. A. 因为school, college, university, hospital, prison, church, table, bed名词等指其用途时，不用冠词。leave college意为“大学毕业”。又因为表示职业或身份的单数名词前通常要用不定冠词，所以选A。

4. C. price前加定冠词表特指。句意为“如果你买10个以上，他们会从那个价钱中减掉20便士”。

5. B. 因为division后有介词短语between…and…的限制，这是特指的，所以要用the。又因为concern作“所关切的事”解是可数名词，所以前面要用冠词。

6. D. 因为house和cottage都是可数名词，且都不是特指，所以都用不定冠词。句意是“威尔逊一家住在大海附近的一栋A形房子里，那是一座17世纪建的别墅”。

7. A. 从next time可知，对方这次住了旅馆，第一空的hotel就是特指这个旅馆，所以用the;第二空的单数可数名词bed不是特指的，所以用不定冠词。句意是：你下次来这里度假，就不要到这旅馆来住了，我在我的公寓里帮你弄张床。

8. D. 虽然understanding是不可数名词，但作“了解、理解”解时，却常常要加不定冠词(尤其是当其前有形容词修饰时)，排除B和C。又因为life作“生活、人生”解，是不可数名词，不是特指，不用冠词。have a better understanding of life指“对生活有更深刻的理解”。

9. B. 虽然通常说the world，但world有定语修饰时，表示“一个…的世界”时，要用不定冠词。题中两个world都有定语修饰，后者是前者的同位语，所以两个都用不定冠词。句意是：这是一个奇妙的世界，一个什么事都有可能发生的世界。

10. C. 因part后面有一定语从句修饰，是特指，用the;又因为“工业革命”是由普通名词构成的专有名词，所以前面也要用the。
