23、上的 that 引导的从句作同一个动词或介词的宾语时，第二个以及以后从句中的 that 不宜省略。如：He said（that）he couldnt tell you right away and that you wouldnt understand 2）当动词 think,make,feel,consider 等后用 it 作形式宾语来代替 that 引导的宾语从句时。We think it necessary that we should practise spoken English every day 3）当 that 引导的宾语从句中的状语紧接 that 时。如：He said t

28、我（我们）认为不”。如：We dont think there is anything of interest in your pictures 2）疑问词（what，how，who 等）do you thinkbelievesupposeimaginesuggest 其它句子成分 这是一个复杂特殊疑问句。它由一个一般疑问句（do you think）和一个特殊疑问句（疑问词其它句子成分）合并而成。如：When do you think he will be back？你认为他会什么时候回来呢？实战演练 1I think its going to be a big problem Yes，it
