问题解答:

我来补答
正确答案是A.
我感觉they前面应该加一个连词,就不会产生歧义了.
因为这是问答,补全问答结构就是.
------When shall we go planting trees in the hill?
------We shall not go planting trees in the hill until it begins to rain. Beacuse they don't need watering when it rains.
因为在问答结构中,回答者为了简便,而做了省略.这里的not until 和后面的they不是同一个句子,所以不用倒装.
如有启发,请采纳.
