Affect vt。影响;影响。等同于袭击。感动刺激(悲伤、愤怒、爱情等感情)

Affect/effect/influence的混合分析

Affect vt。表示“影响,(病)攻”,大部分是指不好的影响。当Affect的宾语是人时,表示它在精神上和感情上都有影响。

,即"使……感动"。

effect 表示"影响"时,是名词,指由于某种原因直接产生的结果,常用短语为:have an effect on对……有影响;in effect正在实行;实际上;side effect副作用;take effect开始实行;开始生效;without effect没有效果;come into effect生效;实施;bring/carry sth. into effect使……生效;be of no effect 无效果。

influence多指对人的思想、观念、心理情绪等内在的东西产生潜移默化的影响,或对人的决定、行为等造成某种程度的影响。

The disease is beginning to affect her brain.疾病逐渐侵袭她的大脑。

We are deeply affected by his devotion to work.他对工作的奉献令我们深受感动。

The book had a great influence on his life.这本书对他的人生影响很大。

He is, in effect, my rival. 实际上,他是我的竞争对手。

单项填空

Sichuan province ___________by the earthquake,causing difficulties to the post-festival road transport.

A. were affected B. was affected

C. had effected D. has affected

解析:选B。affect 为动词,意思是"影响;感动";effect为名词,意思是"影响;效果"。根据句意选择B。

4. appreciate vt.欣赏;感激;意识到;体会;理解

appreciate后可接名词、代词、动名词、名词性从句等作宾语,但不能接不定式。表示"感激,感谢"时,其后的宾语只能为"物",不能为"人"。其后不直接跟if或when引导的从句,若语义上需要接这类从句,需借助it,即:appreciate it if/when ...。

易混辨析appreciate/thank

appreciate 意为"感激,感谢"时的结构为:

appreciate (doing) sth.

appreciate it if/when ...

thank表示"感谢"时的结构为:thank sb. for sth.。

I appreciate your ability very much.我很欣赏你的能力。

We shall appreciate hearing from you again.能再次收到你的来信,我们将十分感激。

I appreciate that you have come here so early.感谢你来得这么早。

I would appreciate it very much if you would help me with it.如果你能帮助我做这件事,我将不胜感激。

●2 They learned this from the way the bones were joined together. 他们是根据(恐龙)骨骼的连接方式了解到这一点的。

句型公式 the way+定语从句
