42、 is a lot of work to be done. (The work has to be done. )請(qǐng)注意下面兩個(gè)句子的含義的不同點(diǎn)：There is nothing to do. (無(wú)事可做，感到十分乏味。)There is nothing to be done. (某東西壞了，無(wú)法使之恢復(fù)正常。)三、不定式符號(hào)to 的保留問(wèn)題有時(shí)為了避免重復(fù)，可以用to 來(lái)代替前面的不定式，這種情況出現(xiàn)在下列動(dòng)詞之后：expect, hope, wish, mean, prefer, care, forget, want, try；或出現(xiàn)在be glad / happy, would lik

I didnt tell him the news. 我沒(méi)有告訴他那個(gè)消息。 Oh, you ought to have. 噢，你本應(yīng)該告訴他的。四、動(dòng)名詞作主語(yǔ)動(dòng)名詞或不定式都可以在句中作主語(yǔ)，但在下列句型中常用動(dòng)名詞作主語(yǔ)。It is / was no use / good + doing sth. It

44、 is / was not any use / good + doing sth.It is / was of little use / good + doing sth. It is / was useless 如：It is no use crying over spilt milk. 覆水難收。It is of little good staying up too late every day. 每天都熬夜沒(méi)有什么好處若主語(yǔ)和表語(yǔ)都是非謂語(yǔ)動(dòng)詞，應(yīng)保持形式上的一致。Seeing is believing.
