　　麻烦各位了.

　　1.getdowntosth,lookforwardto,objectto,payattentionto等等后接sth、v-ing时,to为介词,那可不可以跟todo当状语?why?

　　2.Whenaskedhowtheywerepayingfortheireducation,almostathirdofthestudentssaid……此处为何用asked而不用beingasked?

　　3.Theystayedwithmethreeweeks.me后为什么不加介词?

　　4.Tryhardashewill,he……"Tryhard"是表语还是状语,为什么可提前?Ashelikeshermuch,hedoesgetangrywithhersometimes.这个句子为什么错?为什么一定要用Muchthoughhelikesher,he……?as/though不是可倒可不倒吗?

　　5.Aloneinadesertedhouse,hewassobusywithhisresearchworkthathefeltanythingbutlonely.逗号前的是独立主格结构吗?省略那些东西?

　　6.Therebenosth.sth是单还是复还是均可?意思一样么?
