16. had better (not) do sth. 最好(別)做某事
had better為情態(tài)動(dòng)詞,其后需用動(dòng)詞原形。had better常用縮寫,變成’d better,其否定形式是在其后直接加not。例如:
We had better go now. = We’d better go now.
我們最好現(xiàn)在走吧。
You’d better not go out because it is windy.
今天刮風(fēng),你最好別出去了。
17. have sth. done 使(某事)完成 (動(dòng)作由別人完成)
sth.為賓語,done為過去分詞作補(bǔ)語。例如:
We had the machine repaired.
我們請(qǐng)人把機(jī)器修好了。
注意區(qū)分: We have repaired the machine. 我們(自己)已經(jīng)修好了機(jī)器。
18. help sb. (to) do sth./with sth. 幫助某人(做)某事,其中的to可以省略。例如:
I often help my mother with housework.

Would you please help me (to) look up these words?
請(qǐng)你幫助我查查這些詞好嗎?
