问题补充:
I think it quite that you will finish the work on time if you work hard.
A. probably
B. certainly
C. likely
D. possibly
答案:
A. probably
B. certainly
(答案→)C. likely
D. possibly
解析:考察词性及词义辨析。A也许,可能(副词);B当然(副词);C可能(形容词);D可能(副词);本句中的likely是一个形容词作宾语补足语,前面的宾语it作为形式宾语。真正的宾语是后面的从句。句意:我认为如果你努力你就能准时完成这份工作在完全可能的。一般情况下副词是不能作为宾语补足语的。故C正确。
