　　答案：①to produce computers　②to land on the moon 基础知识巩固 答案：therefore　 考查副词。句意：我们希望我们会在工作市场上起更大的作用，因此提供更多的工作。 答案：ever　本题考查省略句。句意：这里的气候宜人，________，在夏季气温极少达到30摄氏度。if ever如果曾经有；如果曾经发生。根据句中的关键词quite pleasant(宜人)，rarely(极少)可知，空格处表达的意思是“如果曾经有(if ever)”。if ever相当于if it(the temperature) ever reached 30℃ in summer。 答案：stayed　本题考查虚拟语气。句意：我们宁愿我们的女儿和我们一起待在家里，但是那是她的选择，她已经不再是一个小孩子了。would rather后接that从句时，要用虚拟语气，如果与现在或将来事实相反，从句用一般过去时态；如果与过去事实相反，从句用过去完成时。根据后面的it is her choice可以判断这件事情还没发生，因而从句用一般过去时。 答案：up　句意：狗熊在夏天和秋天开始脂肪的储存以使他们有足够的能量来度过冬眠。 答案：so　本题考查省略。句意：听起来好像是车的发动机出毛病了。如果这样的话，我们最好立刻把它带到修车厂去。if so“如果这样的话”。 答案：leading　本题考查非谓语动词。根据本句的结构来看，引起的关注正是这条消息令公众震惊的同时所引起的结果，即结果状语，而作结果状语，且表达主动意义。句意：这条消息令社会震惊，引起了人们对在校学生安全的极大关注。 答案：If　答语句意：如果可能的话，我要去看望乡下的父母。if possible如果可能的话。 答案：inviting　考查非谓语动词。句意：起初，我后悔邀请他们留下来，但是我们很快成为了朋友。regret doing后悔做了某事。 答案：decorating　考查动名词作主语。句意：我这个周末过的很忙很累，因为装饰圣诞房子花了我一整天。because引导原因状语从句，从句中的cost是谓语，前面是主语，用动名词作主语。 答案：became　考查虚拟语气的用法。句意：难道你不想让你的孩子在学业上成功，获得奖学金吗？would rather后面的从句用虚拟语气，即用动词的过去式形式。 答案：it　考查代词。句意：新的技术已经让以更低的成本更快地生产出新的产品成为可能。根据句意可知，it在句中作形式宾语，真正的宾语是后面的不定式。 答案：eating　句意：——为了有一个苗条的体形，范妮尝试了许多方法，但都徒劳。——因此现在她被迫晚饭什么都不吃。be reduced to doing sth.沦落到做某事，陷入……的境地。 答案：from/of　free...from/of...使……免于……。 答案：it　本题考查代词。句意：去年平均降了18.75厘米的雨，使其成为自1850年加利福尼亚成为州以来最干旱的一年。由语境可知，此处考查的是代词的替代，替代前面提到的last year，为同名同物，同一者，用it。 5．Before going abroad, you must exchange your money with some dollars.__________________ 6．I found my father sitting at his table, was lost in thought.__________________ 7．It is raining outside.
