| A. | do; send | B. | did; send | C. | had; sent | D. | has; sent |
分析 --你知道到目前为止中国多少次把宇航员送到了天空吗?
--三次.
解答 答案:D
根据so far,可知so far是现在完成时的标志词.现在完成时态表示过去发生或已经完成的动作对现在造成的影响或结果.或从过去已经开始,持续到现在的动作或状态.本题属于表示过去发生或已经完成的动作对现在造成的影响或结果,现在完成时态的构成:助动词have/has+过去分词,根据主语China是第三人称单数,所以应该用has sent,故选:D.
点评 本题主要考查动词时态,做此类题目要注意时间状语、标志词.根据上下文所表达的含义,做出判断.同时更应记清时态的构成形式.就本题而言,主要考查现在完成时态.
