所謂溫故而知新,前五點(diǎn)大家要記得回頭認(rèn)真瞄一眼。

6、不定式作表語與?to?的省略

當(dāng)不定式用作表語的時(shí)候,其中的to 原則上是不能省略的。如:

His aim is to make a million dollars in ten years. 他的目標(biāo)是十年掙一百萬。

This wall made of stone was to keep the cattle out。這堵墻為的是不讓牲畜進(jìn)來。

但有一種例外,那就是當(dāng)主語部分有動(dòng)詞do的某種形式時(shí),用作表語的不定式可以省略to。如:

All I did was (to) touch the vase, and it broke all of a sudden. 我只不過碰了一下窗戶,它突然就碎了。

7、并列不定式與to的省略

當(dāng)兩個(gè)或多個(gè)作用相同的不定式并列時(shí),通常只需在第一個(gè)不定式前用to,其余不定式前的to 可以省略。如:

I’d like to go to sleep and(to)have a good rest。我想躺下休息了。

Will you go to the America or (to)the Africa? 你要去美洲還是非洲啊?

但是,如果兩者有對(duì)比關(guān)系,則后面不定式前的to不可省略。如:

To try and fail is better than not to try at all. 嘗試而失敗總比不嘗試好。

8、固定搭配與to的省略

1. let類固定搭配:let fall (無意中說出),let fly(發(fā)射、攻擊),let go (放開),let slip (放走),live and let live (自己活也讓別人活)等。如:

She let slip an opportunity to study abroad. 她錯(cuò)過了出國留學(xué)的機(jī)會(huì)。

He arranged all and then let fly. 他安排好了之后便開了槍。

I got to know what was going around from a few words she let fall. 我從她說的幾句話中猜出發(fā)生什么事了。

2. make類搭配:make believe (假裝),make do (湊合著用)等。如:

The girls made believe (that) they were angles.女孩子們假扮成天使。

We were in a hurry so we had to make do with a quick snack. 我們時(shí)間很緊,只好胡亂吃了頓小吃。
