选C,帮我分析一下.并翻译一下.

解答:

1.We want to be pilots and ( ) the largest
planes in the world.
选B.并列的动词不定式,fly 之前省略了to.

2.----Why was he fined?
----He happened to ( )flowers in the
park.
A.find picking
B.see to pick
C.be caught picking
D.notice picking
选C.happen to do sth(碰巧做某事)是个固定搭配.而be caught doing sth意为:因为做某事而被捉.所以选C是正确的.
