1.-DO you have any idea what paul does all day?
-as i know,he spends at least as much time playing as he(does writing)
2.as the years passed,many occasions-birthdays,awards-(were marked)with dad's flowers
3.-i'm going to leave at the en of this month
-i don't think you shoul do that until (you've found )another job
4.-he promisedto come on time.
-what do you imagine (has happened)to him then为什么不用HAPPENING?
5.as soon as he comes back,i will tell him when(you will come and see him)为什么不用一般现在时表示将来动作
6.are you still busy?
-yes,i(am just finishing )my work,an it won'ttake long,

1、he spends at least as much time playing 和he(does writing)是平行结构,括号里的内容可省略
2、好想不能有were
3、这是完成时的用法,仔细体会一下就知道了
4、括号好想应该加在do you imagine上,这是插入语,主句是what has happenedto him then,如果用heppening句子结构就不完整了
5、这是宾语从句,不同于条件从句
6、好像I 也在括号内吧 ,这样就好理解了

1.does 是助动词,来代替前面的spends
2.因为这句中暗含的时时是过去的.
3.因为这句中的时间是将来的.
4.因为这句中少谓语.happening是非谓语形式.
5.因为这个从句是宾语从句而不是时间状语从句.
6.这句是用现在进行时表示将来时.
