— _________ I use your telephone?

— Yes, of course.

A.Would

B.May

C.Should

D.Must

答案

答案:B

题目分析:句意:我可以用你的电话吗。当然可以。情态动词may表示许可或征求对方的许可,有“可以”的意思。should是应该的意思,must是必须的意思。故选B.

点评:情态动词是中考的必考语言点。情态动词表必要性时用must(必须)与don’t have to / needn’t(不必要);表推测时用must (肯定、一定)与 can’t/couldn’t (不可能);表请求和许可时can/may(可以、能够)与can’t/mustn’t(禁止、不许)。

These proprietary packages, however, of which there am still many inexistence, do not address the problem of universal interconnect ability, or open systems interconnection. In an attempt to alleviate this problem, (5) , in the late 1970s, formulated a reference model to provide a common basis (or the coordination of standards developments and to allow existing and evolving standards activities to be placed into perspective with one another.
