“疑问词+­ever”引导的从句

Howeverno matter how different they may seemall over the worldthe spirit of sharing joygratitudeloveor peace is common in all festivals.

然而,无论它们看起来多么不同,在这个世界上,分享快乐、感恩、爱或和平的精神是所有节日共有的。

(1)句式分析:这是一个主从复合句。no matter how different they may seem是让步状语从句;the spirit of sharing joy,gratitude,love,or peace is common in all festivals是主句,是主系表结构。

(2)句首的However是副词,意为“但是;不过;然而”。however作此用法时,可置于句首、句中或句末,但必须与句子的其他成分用逗号分隔开来。

(3)句中no matter how引导让步状语从句,表示“无论如何”“不管怎样”,可替换为however。

[思维拓展]

“疑问词+­ever”引导的从句:

(1)whenever,wherever,however引导让步状语从句,相当于no matter when/where/how。

(2)whatever,whoever,whichever,whomever既可引导名词性从句,也可引导让步状语从句,在引导让步状语从句时相当于no matter what/who/which/whom。

(3)“no matter+疑问词”只能引导让步状语从句,可放在主句前或主句后。

However(=No matter how) hard you shout,Granny won't be able to hear you.

不管你叫得多响,奶奶都听不到你的声音。

Sailing in rough weather can be very unpleasant.However,we found it exciting.

天气不好的时候航行很可能不畅快。然而,我们却觉得很刺激。

“动词+形式宾语it+宾补+真正的宾语”结构

Online shopping websites and social media apps have made it much easier for the public to spend more on gifts for their loved ones.

在线购物网站和社交媒体应用程序让公众更容易为他们心爱的人花更多的钱买礼物。

(1)句式分析:这是一个简单句。主语是Online shopping websites and social media apps,谓语是have made,it是形式宾语,easier是宾语补足语,to spend more on gifts for their loved ones是真正的宾语。

(2)“动词+形式宾语it+宾补+真正的宾语”结构:

①能用于上述结构的动词有make,think,find,believe,feel,consider;

②宾补的两种常见形式:形容词、名词(词组);

③真正的宾语的常见形式:不定式(短语)、v.­ing(短语)、that引导的从句。用v.­ing(短语)作真正的宾语时,宾补通常是no use,no good,fun等;

④当真正的宾语为不定式时,不定式可有自己的逻辑主语,该逻辑主语用for引出。该结构中的“形式宾语it+宾补+真正的宾语”有时可改写为宾语从句。

I feel it our responsibility to protect the environment.

我认为保护环境是我们的责任。

No matter where he is,he makes it a rule to go for a walk before breakfast.

无论他在哪儿,他都习惯在早餐前散步。

He made it clear that he wanted me to stay for another week.

他清楚地表示他希望我能再待一周。

It was the culture,rather than the language,that made it hard for him to adapt to the new environment abroad.

是文化,而不是语言,使得他很难适应国外的新环境。

I can understand why astronauts find it difficult to readjust to life on earth.

→I can understand why astronauts find that it is difficult to readjust to life on earth.

我能够理解为什么宇航员觉得重新适应地球上的生活不容易了。

注意:“make+it+adj./n.+(for sb./sth.) to do sth.”结构在高考中常考查it作形式宾语的用法及宾补后面的非谓语动词的形式。在英语中形式主语和形式宾语只有it可以充当,其他词没有此用法。

allow 的常见用法

They are occasions that allow us to relax and enjoy lifeand forget about our work for a little while.

它们是让我们放松,享受生活,暂时忘记工作的机会。

(1)句式分析:这是一个主从复合句。主句是They are occasions,使用了主系表结构,后面是that引导的定语从句。

(2)句中allow 的意思是“允许”。allow 还可作“给予”讲。allow 的常见用法:

 

 

 

 


()

We allow smoking only in restricted areas.

我们只允许在指定的地点吸烟。

My parents don't allow me to go out at night.

我父母不允许我晚上出去。

He is not allowed to stay out late.

他不可以在外待到很晚。

He allows his son too much money.

他给他儿子的钱太多了。

不定式短语作原因状语用法

And if you study festivals carefullyyou may be surprised to find that different cultures actually have a lot in common after all.

如果你仔细研究节日,你可能会惊讶地发现不同的文化其实有很多共同点。

(1)句式分析:这是一个主从复合句。主句是you may be surprised to find,前面是if引导的条件状语从句,后面是that引导的宾语从句。句中不定式短语to find... 作原因状语。

(2)不定式短语作原因状语用法浅析:

①形容词多是表示情感、感觉或心理活动的happy, pleased, surprised 等;

②不定式的逻辑主语一般为句子的主语,若不是,则在不定式前加上其自身的主语;如果强调不定式动作先于谓语动作或谓语所表示的状态,则不定式用完成式。

We are very happy to cooperate with you in this project.

在此项目中与你们合作,我们非常高兴。

He is very glad for his son to have made such great progress.

儿子取得了非常大的进步,他高兴极了。
