10、炸裂，突然破裂。由句意“蒸气压力过高的锅炉突然破裂了”可知，用一般过去时最合适，因此答案选 A。3. 解析：选 A。考查短语搭配。exist on 靠活下去(靠生存) ；exist in 在中存在(或生存) ； exist by 在( 某种思想、品质等 )中找到生活的力量；exist with 与共存。由句意“他靠面包和水度日” 可知，答案选 A。4. 解析：选 C。句意为：村民们在协议达成之前彼此之间经常发生暴力冲突。由常识可知，冲突不应是“有趣的” ，也不会是“ 平安的或和平的”。 “精神冲突”亦不合适，只有“暴力的冲突”才符合句意，故选 C。5. 解析：选 B。考查固定短语。句意为：寒冬
11、对橘子树有害。be harmful to . 对有害。6. 解析：选 D。考查短语辨析。 in surprise 吃惊地；in return 作为回报；in turn 轮流，依次；in time 终于，一段时间后。由句意“ 她起初只是一名办公室职员，最终成了整个公司的董事 ”可知，应选 D。7. 解析：选 B。考查动词短语的用法。prevent .from doing 意为“阻止做某事”，同义短语还有 stop/keep .from doing,其中 prevent/stop .from doing 中的 from 可省略，而 keep .from doing 中的 from 不能省略，排除 A 项；happen 为不及物动词，不用被动语态，故选 B。8. 解析：选 A。句意为：一切按计划进展得很顺利。 according to 根据,按照，是固定短语。9. 解析：选 C。句意为：她对她的将来感到迷惘。puzzled （人）迷惑的、迷惘的; puzzling（物）令人迷惑的。10. 解析：选 B。考查 lie (lied,lied)说谎；lie (lay,lain)躺，平卧；和 lay (laid,laid)放置；下蛋这几个词的区别。句意为：躺在树下的那个男孩向他的朋友撒谎说他的公鸡下蛋了。故选B。
