1.选A learn to do swim 学游泳 句子意思:他在海里学游泳
2.选B 这题可以用排除法,看某人做什么事有两种表达:watch sb do sth 或者watch sb doing sth
这里只有B 是正确的搭配.
find sb do sth.就是讲发现某人做了什么事,是发现了整个过程,而find sb doing是发现某人正在做什么事,发现了一部分而已.
这里的语境是:我正在看孩子们玩,孩子们正在玩,所以选择B.
1. choose A because C&D are impossible, so don't even think about it. If you choose B, then you have to change "learns" in to "learned."
2. choose B because children is a plural noun, so A is incorrect. I don't know how to explain why not choosing C&D, but they are the wrong answers
A 学习做某事(to do表示目的,学习游泳)
B 宾语补足语,看着孩子们打球
learn to swim
playing
