题目内容
3.Tom rushed into the house______ his mother was cooking.( )| A. | as | B. | before | C. | while | D. | after |
分析 当汤姆冲进屋里时,他的母亲正在做饭.
解答 答案:C as由于; 像,像…一样; 同时,当…时;若要表示两个正在发展变化的情况,相当于汉语的"随着",一般用as;before,在…之前; while而; 虽然; 在…期间; 与…同时;after,在…之后;若主、从句表示两个同时进行的持续性动作,且强调主句表示的动作延续到从句所指的整个时间,通常要用while;从句意可以看出rushed into the house与was cooking是同时发生的,意为"当…时候".故选C,
点评 连词在句子中主要起联系上下文的作用,他们之间的区别就是表示逻辑关系的不同,所以在解题时先要理解上下文含义,然后根据上下文逻辑关系选择合适的连词.
