典题•热题•新题 例1(全国)Jumping out of airplane at ten thousand feet is quite exciting experience. A./;the B./;an C.an;an D.the;the 思路分析: airplane在此是泛指的概念，experience作“经历”解释时，是可数名词。 答案: C 深化升华 注意此处空半格题中is说明句子叙述的是一种没什么时间性的事情，所以不是叙述某一次从某一架飞机上跳下来。飞机不能特指。 例2(广东)I feel that one of my main duties a teacher is to help the students to become better learners. A.forB.byC.asD.with 思路分析: 依据题意，此处应选择表示“作为”的as。题意：我认为作为一名教师，我的主要责任之一就是帮助学生学习。 答案: C 例3(浙江) modeling business is by no means easy to get into,the good model will always be in demand. A.WhileB.SinceC.AsD.If 思路分析: while此处表示让步，意为“尽管”。其余各项均不符合题意。 答案: A 例4(上海) Americans eat vegetables per person today as they did in 1910. A.more than twiceB.as twice as many C.twice as many asD.more than twice as many 思路分析: 本题考查了as many...as...结构的用法。凡修饰比较等级的成分只能放在比较等级的前面，不能放在中间或后面。 答案: D 深化升华 注意此处空半格as...as...前面是表示倍数的词，再前面是修饰倍数的词。 例5(上海)Is this the reason at the meeting for his carelessness in his work? A.he explainedB.what he explained C.how he explainedD.why he explained 思路分析: the reason后接定语从句时，若从句中不缺主语或宾语，就用why引导，若缺少上述成分，则用that或which。本题中因the reason作explained的宾语，故省略了that或which。 答案: A 深化升华 注意此处空半格不能看到reason作先行词就选why,要分析reason在从句中所作的句子成分。 (责任编辑：admin) |
