第一节 情态动词和虚拟语气

考点一：情态动词

1.It is required by the rules that students ______ get grades not lower than 85 in any subject in order to get the scholarship.

A. will B. may

C. shall D. would

【解析】C 句意：根据规定，学生如果想拿奖学金，任何单科成绩不得低于85分。shall用于第三人称，在条约、规定、法令等文件中表示义务或规定，意为“应，必须”。

2.They are brothers, but they do not always agree with each other as they ______. Quarrels break out now and then.

A. can B. should

C. may D. will

【解析】B 句意：他们是兄弟。但是他们却并不像本来应该的那样总是赞成对方(的观点)。争吵时常发生。根据句意可知，此处应用should表示“应该，应当”。

3.According to the newly-made traffic regulation, whoever drive through red light ______ be fined at least 200 dollars.

A. shall B. may

C. would D. should

【解析】A 句意：根据最新颁布的道路管理条例，任何闯红灯者将被罚款最少200美元。shall用于第三人称，在条约、规定、法令等文件中表示义务或规定。

4.—Hi, Lucy. Do you know where Linda is?

—She ______ in the library. I met her there just a few minutes ago.

A. shall be B. must be

C. should have been D. might have been

【解析】B 句意：——你好，露西。你知道琳达在哪里吗？——她一定在图书馆。几分钟前我在那里见到她了。设空处表示对现在的推断，故排除C、D两项；must(一定)符合本题要求。shall与第二、三人称连用，用于陈述句表示说话者给对方的命令、警告，不符合本题要求，故被排除。

5.—I don't know what to get for my father's birthday.

—You ______ buy him a T-shirt. There are many new styles in the shop.

A. need B. could

C. would D. shall

【解析】B 句意：——我不知道该为我父亲的生日买什么礼物。——你可以给他买件T恤衫。商店里有很多新款式。考查情态动词could表示可能性。need作情态动词时不能用于肯定句；would常用于虚拟、请求或过去经常发生的事情；shall用于第二、三人称表示说话者的命令、警告、威胁、允诺等语气。

6.—The weatherman on the news said it might rain later on this afternoon.

—Well, I ______ take my umbrella along with me today.

A. can B. may

C. could D. must

【解析】D 句意：——新闻中的天气预报员说今天下午晚些时候可能有雨。——哦，我今天必须带雨伞。根据句意可知must(必须)符合语境。can/could可能，能够；may也许。

7.—It was really tiring for me to stand in the queue for two hours to get the G-train ticket.
