1.It will take us at least three days ________ the difficult job.
A．to finish B．finish
C．finishing D．finished
句意：完成这项困难的工作至少需要三天时间。
考查非谓语动词。根据题干可知，本句考查的是固定句型：It takes sb some time to do sth，意为“花费某人多长时间去做某事”，其中It是形式主语，真正的主语是后面的动词不定式，本句时态是一般将来时。故选A。
2．My parents allow me ________ games on the Internet on Friday evening.
A．playing B．to play
C．play D．to playing
句意：我父母允许我周五晚上在网上玩游戏。
考查非谓语动词。allow sb to do sth为固定搭配，意为“允许某人做某事”，所以填动词不定式。故选B。
3．We hope ________ to the mountains this afternoon.
A．go B．to go
C．went D．going
句意：我们希望今天下午能去山里。
考查非谓语动词。hope to do sth“希望做某事”，为固定短语。故选B。

A．open B．opened
C．to open D．opening
句意：王叔叔很擅长烹饪，他决定开一家自己的餐馆。
考查非谓语动词。根据“decides...his own restaurant.”可知，此处是decide to do sth.“决定做某事”，为固定搭配，所以空处应填动词不定式to open。故选C。
