10、。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：寒冬对橘子树有害。be harmful to . 对有
