高中英語(yǔ)語(yǔ)法重點(diǎn)難點(diǎn)回顧(2)

這座新樓是那座舊樓的四倍大(四倍高)。［高三倍］

A is three (four, etc.) times as big (high, long, wide, etc.) as B.

Asia is four times as large as Europe.亞洲是歐洲的四倍大。

A is three (four,etc.) times bigger (higher, longer, wider) than B.

例如:Your school is three times bigger than ours.

你們的學(xué)校比我們的學(xué)校大三倍。

表示兩倍可以用 twice 或 double。

表示“較高程度”的形容詞，如excellent，extreme，perfect等，沒(méi)有更高級(jí)，也不能用比較級(jí)。

如果復(fù)數(shù)名詞前有many、few，不可數(shù)名詞前有much、little等表示量的形容詞時(shí)，該用so而不用such。如：

I've had so many falls that I'm black and blue all over.

Mr White got so little money a month that he could hardly keep body and soul together.

但little不表示數(shù)量而表示“小”的意思時(shí),仍用such。如:

They are such little children that the they cannot clean the house by themselves.

6)almost與nearly

在very, pretty, not后用nearly, 不用almost。例如：

I'm not nearly ready.

在any, no, none, never前用almost, 不用nearly。例如：

I almost never see her.

need 表示“需要”或“必須”,作情態(tài)動(dòng)詞時(shí),僅用于否定句或疑問(wèn)句中。在肯定句中一般用must, have to, ought to或should 代替。例如：

You needn't come so early.

Need I finish the work today? －－Yes, you must.

注意：needn't have done“表示本來(lái)不必做某事而實(shí)際上做了某事”。例如：You needn't have waited for me.

“should have done”表示應(yīng)該做到而實(shí)際上沒(méi)有做到。

You should have started earlier.

“ought to have done”表示過(guò)去應(yīng)做某事而實(shí)際未做。

You ought to have helped him (but you didn't)

書(shū)報(bào)的標(biāo)題,小說(shuō)等情節(jié)介紹常用一般現(xiàn)在時(shí)。

表示感覺(jué),愿望和狀態(tài)的某些動(dòng)詞如have, be, hear, see, like等詞一般不用進(jìn)行時(shí)。

有些動(dòng)詞形式上是主動(dòng)結(jié)構(gòu),但表示被動(dòng)的意思。常見(jiàn)的有可和 well, easily 等副詞連用的不及物動(dòng)詞sell,wash,write,read,clean,cook等。例如：

The cloth washes well.這布很經(jīng)洗。

The new product sells well.這新產(chǎn)品很暢銷(xiāo)。

The pen writes well.這支筆很好寫(xiě)。

在動(dòng)詞 arrange,command, demand, desire,insist, order,propose, request, require, suggest等后面的賓語(yǔ)從句中用“(should)＋ 動(dòng)詞原形”(虛擬語(yǔ)氣)例如：

We suggested that we (should) have a meeting.

We insisted that they (should) go with us.

The doctor ordered that she (should) stay in bed for a few days.

He demanded that we (should) start right away.

作advice,idea,order,demand,plan,proposal,suggestion,request等名詞的表語(yǔ)從句和同位語(yǔ)從句,其謂語(yǔ)動(dòng)詞要用虛擬語(yǔ)氣的結(jié)構(gòu)“(should)＋動(dòng)詞原形”。例如：We all agreed to his suggestion that we(should) go to Beijing for sightseeing.

My idea is that we (should) do exercises first.

在feel, hear, notice, observe, see, watch, have, let, make等詞后的補(bǔ)足語(yǔ)中,不定式不帶to。但是這些句子如果變成被動(dòng)結(jié)構(gòu)時(shí),就必須帶to。例如：I often hear him sing the song.

He is often heard to sing the song.
