It is absolutely essential that William ______ his study in spite of some learning difficulties.[     ]

A. continue

B. continued

C. has continued

D. would continue

答案

A

解析

考查虚拟语气。

在it+is+形容词+that句型中,当形容词为necessary,important,essential等时,that从句应该用虚拟形式(should+v.),从句中的should通常可以省略,故本题选C。

考点名称:虚拟语气

虚拟语气的概念:

虚拟语气用来表示说话人的主观愿望或假想,所说的是一个条件,不一定是事实,或与事实相反。在条件句中的应用条件句可分为两类,一类为真实条件句,一类为非真实条件句。非真实条件句表示的是假设的或实际可能性不大的情况,故采用虚拟语气。
