1.(One more time) ,and i'll get the work finished.
(One more time 在此处是什么成分?为什么不能用Given one more time
若用Given one more time后可直接加i'll get the work finished,为什么?)
2.I think all these are main points( worthy of) much attention.
(worthy of是否可换成which worthy of,为什么?)
3.(He has been told) many times,but he still can't understand it.
(He has been told是否可替换成having been told?为什么?
但1 中 ,and前就可无主语,为什么?)
4.Only作句首,何时倒装,合适不倒装。Only to do 表示什么意思?
以上。。
