) 12.______ people breathe when they are under water?
A C
再问： 为什么，请详细解释下
再答： 第一题考查 的是情态动词 翻译过来是 当人们在水底下的时候 ~~~ 呼吸吗 ？ 很明显 用CAN 可以的意思 B的话弱是应该呼吸吗？ 明显是错误的 C是必须呼吸吗？ 也是错误的 D也是可以的意思？ 但MAY语气比CAN弱些 且MAY用于请求 所以选A 第二题是固定搭配 IN ONE'S MIND 在某人脑海中
再问： 下一题也答下。
再答： 第三题选B 这题首先是陈述句， 用what we can do 而不是what can we do what we can do 是正常语序 因为此句是陈述句 HOW是错误的 因为 C D选项 HOW后面没有宾语
