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:

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。
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：

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.
注意：不定式動(dòng)詞在介詞but, except, besides后面時(shí),如果這些介詞之前有行為動(dòng)詞do的各種形式,那么,這些介詞后的不定式不帶to,否則要帶to.如：
She could do nothing but cry.
What do you like to do besides swim?
I have no choice but to go.
