he ----the ladder while ----on the tree.
a,fell down from;reaching for the apple
b.fell down; he reached for the apple
c.fell off; he reached for the apple
d.fell off; reaching the apple
正确答案是C但我认识应该是A,while 后面不应该跟现在进行时吗?而且主句和从句主语一致,从句可以省略主语 +be.

d.
fall off...从...摔下
while连接动名词或者正在进行的动作
reach for 是伸手拿某物
这里表达的他正好够到某物,reach sth
D
d
D
fell off 这里用off 较好,表示人的身体与梯子分离。
while 后接动词ing 形式说的很简洁,很好。
所以选D
reaching for 或者 he reached for都可以
关键是从梯子上掉下来是用fall off
而fall down一般偏指摔倒或者坍塌
