高考试题赏析

There is nothing more I can try ____ you to stay, so I wish you good luck.

A. being persuaded B. persuading

C. to be persuaded D. to persuade

赏析：I can try ____ you to stay为定语从句，修饰先行词nothing，省略了作try宾语的关系代词that,选项to persuade在定语从句中作目的状语。答案：D

[发散思维]persuasion n.说服,劝说，信服 persuasive adj.有说服力的，令人信服的

辨析：persuade与convince

persuade和convince两者均为 “说服”，前者着重感情上的“督促，劝告”，后者着重理智方面的“辩论，证明”，两者结构相同。persuade(convince)sb. that/of sth.意为“说服某人……”。

He persuaded me that it was not worth buying.

他说服我说那东西不值得买。

高考试题赏析

Scientists are convinced ____ the positive effect of laughter ____ physical and mental health.

2.She is not sure which brand she should buy, so she has asked you to listen to ads from different companies.

她不确定应该买哪个品牌，所以她请你去听来自不同公司的广告。

which在此作定语，修饰brand。which brand she should buy为宾语从句。

should是情态动词，是shall的过去式，意为“将，会，应该”。

[链接]should的特殊用法：

(1)表示语气较强的假设。如：

If he should fail to come, ask Comrade Chen to work in his place.

万一他不来，就叫陈同志代替他的职位。

Should it rain tomorrow/If it should rain tomorrow, the meeting would be put off. 万一明天下雨，会议将会延期。

(2)表示可能性、推测或推论，意为“可能，应该”。如：

They should have arrived in Beijing by this time.

他们这时应该到北京了。

The North Lake should be beautiful, but it is now heavily polluted.

北湖本应当非常漂亮的，但是现在被严重污染了。

(3)表示委婉、谦逊，意为“可，倒是”。如：

I should think so. 我倒是这样认为的。

(4)可与why, who, how等连用，表示意外、惊异等，有“竟会”之意。如：

Why should you be so late today? 你今天怎么来得这么晚？

高考试题赏析

____ fired, your health care and other benefits will not be immediately cut off.

A. Would you be B. Should you be

C. Could you be D. Might you be

赏析：该题考查虚拟语气。句意为“如果你被解雇，你的医疗保险和其他利益并不会立即取消”。与将来事实相反的假设，可用should,不可用would,could, might。答案：B

注意：“should+完成式”表示“本应该怎样而未怎样”，“should not+完成式”表示“本不应该怎样而怎样了”。
