It is important ( necessary, right, strange, natural.) that . 该句型和上一个同属一个句型;由于主句中的形容词不同,that 后的从句中要用虚拟语气(should + 动词原形),should 可以省去,建议记住该句型中的形容词。It is important that

It is a pity that he is ill. 他生病了,真遗憾!4It is said (reported/ learned/believed/thought/known/told/hoped.) that . 该句型中的it 仍是形式主语,真正主语是that 引导的主语从句;该结构常译为据说(据报道,据悉)。 It is said that he has come to Beijing. It is reported that another earth satellite has been put into orbi
11、t. It is suggested ( ordered /demanded/insisted/commanded. ) that . 该句型和上一个同属一个句型,主句中的过去分词是表示请求,建议,命令等词时,that后的从句要用虚拟语气(should + 动词原形),should 可以省;常译为据建议;有It is suggested that the meeting ( should ) be put off. It was ordered that we ( should ) arrive there in two hours.配套练习1._(据报道)that dozens of chi
