Because banana plants yield only one bunch of fruit, each plant is cut down after produces bananas.  

after有prep和conj两种形式，但是无论是哪一种形式都不可能出现after 直接连接 动词的，所以因该改为after prouducing bananas比较好。

Small to medium-sized marsh birds similar in body shape by cranes, rails are found throughout the world, except in the polar regions   

shape和cranes之间是所属关系，应该用of 而不是用by.

xkfy0521

Small to medium-sized marsh birds similar in body shape by cranes, rails are found throughout the world, except in the polar regions

应该是similar.....to.......

Photographer Edward Steichen constantly experimented new techniques and materials in his quest to have photography accepted as a creative art.   

experimented with new 因为experiment是不及物动词

挖,这么块就有人回答,多谢帅哥,美女

linlin315

Photographer Edward Steichen constantly experimented new techniques and materials in his quest to have photography accepted as a creative art.   

选择A的原因是experiment这个词本身是个不急物的动词，所以他后面是无论如何都不能加宾语new techniques and materials的，所以应该将其改成experimented on

以下是引用xkfy0521在2004-4-14 9:01:00的发言：

Small to medium-sized marsh birds similar in body shape by cranes, rails are found throughout the world, except in the polar regions

应该是similar.....to.......

experiment 不及物动词，(常和on ,with连用)做试验
