问题
单项选择题
The environmental group hopes ______ the forest to its original condition by the end of the decade.
A.having restored
B.to have restored
C.to be restored
D.to have been restored
答案
参考答案:B
解析:从四个选项的区别点可以看出,此题的考点是非谓语动词的用法。hope要求接不定式作宾语,而不是hope doing sth. 。另外不定式restore的逻辑主语是group,相互关系应该是主动的,所以C和D都是错误的。正确答案为B项to have restored,此处用完成式表明到将来某一时刻(by the end of the decade)要完成的动作。
