选什么？为什么？
A.young ducks know how to swim B.swimming is known by young ducks
C.the knowledge of swimming is gained by young ducks
D.how to swim is know in young ducks
选什么？为什么？
选A．ON HATCHINGY应该表示刚被孵化出来，整句话（加上选项）就是小鸭子一被孵化出来就会游泳．所以是”小鸭子被孵化”，”小鸭子会游泳”主语应该都是小鸭子才不别扭．
A，应该用主动句，因为分词是主动的
选A
找状语on hatching的主语，也就是A中的young ducks啦
选A，因为句子缺少主语
