I wonder whether you can change this note for me.,3)动词+间接宾语+宾语从句,She told me that she would accept my invitation.,2.作介词的宾语,Our success depends upon how well we can cooperate with one another.,3. It作为形式宾语,He has made it clear that he will not give in. See to it that children dont catch cold.,4.否定的转移,主句的谓语动词为think, consider, suppose, believe, expect, fancy, guess, imagine等, 其后的宾语从句若含有否定词not, 一般要把否定词not转移到主句谓语上, 从句谓语用肯定.,I dont think this dress fits you well.,5. that不能省略的情况,1)and连接两个宾语从句,that宾语从句放在and后,Everybody could see what happened and that Tom was frightened.,2)that引导的宾语从句作介词宾语时,I know nothing about him except that he is from the south.,3)that从句位于句首时,That he ever said such a thing I simply dont believe.,4)主句谓语动词与that从句之间有插入语时,We decided, in view of his special circumstances, that we would admit him for a probationary.,6.宾语从句的时态,1)主句用过去时,从句用一般过去时(如从句表示客观真理,可用现在时),Did you see that the boys were playing football on the playground at that time? Yesterday Tom said that the earth goes round the sun.,2)主句为现在时时,从句可根据需要选用各种时态,I think that the Greens have left for Hawaii. I want to know if/whether he will go surfing this afternoon.,3)动词suggest(建议), insist(坚持,主张), prefer(宁愿), request(要求), require(要求,命令), demand(要求), order(命令), command(命令), advise(建议)等词后的宾语从句中, 谓语动词要用虚拟语气, 其构成是“should+动词原形”，其中should可省略,It was suggested that more teachers should be sent there to help them.
