题目内容
14.-The local living conditions (条件) have improved a lot ______China set up the city of Sansha.-And more and more people would like to go there for business.( )
| A. | before | B. | when | C. | since | D. | after |
分析 -自从中国建成了三沙市以来,当地的生活条件已经改善了许多.
-越来越多的人们愿意去那儿做生意.
解答 答案:C;before在…之前;when当…的时候;after在…之后;since表示"自从.以来",表示的动作是从过去以来一直持续到现在,所以since引导的从句要用一般过去时态,主句只能用现在完成时态,根据句中的"The local living conditions (条件) have improved a lot自从中国建成了三沙市以来",它是完成时态的句子,可知后面的时间状语从句用since引导,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.连词的用法都比较多,语义之间还有交叉,熟记其基本应用规则,了解其区别,注意固定搭配对象,是做好此类题型的关键.
