题目内容
19.The boy the first prize,but he was so careless as to make a foolish mistake.( )| A. | must have gained | B. | need have gained | ||
| C. | could have gained | D. | shall have gained |
分析 这个男孩本来是可以获得一等奖的,但是他如此大意以致于犯了这个愚蠢的错误.
解答 答案:C
考查虚拟语气,but后面是一种事实情况,如果他不粗心大意的话,他能获得一等奖,事实是他没有获得,说的是与过去事实相反的假设,所以要用would/should/could/might+have done,故答案选C.
点评 虚拟语气是高考经常考查的内容,也是英语学习中的一个难点.虚拟语气用于表示说话人的假想、建议或主观愿望,所表示的假设并不是事实,而是不可能或是不大可能发生或实现的,除了掌握if条件句引导的虚拟语气之外,还要掌握一些与虚拟语气有关的固定句型结构,首先,判断是否需要使用虚拟.其次,结合虚拟语气句式,判断需使用何种时态及句式是解题的关键.
