1. A.
   to do
2. B.
   doing
3. C.
   with
4. D.
   to be doing

Answer 1

A
the other exercise（其他练习），意味着不同于这个(this one)练习，故不表示“继续做原来的事情”，所以用go on to do表示。本题考查同形词组的区别。做这一类题的关键是要从语境来判断前后是同一件事情还是不同的两件事。又如：The soldiers went on to dig the fields, after they helped the villagers get in the wheat.帮助村民们收割完小麦后，战士们继续挖地。
