【问】 Come winter，we'll have to pay a good deal more for vegetables and fruit.请问句中的come winter为什么不保持主谓一致关系?

【答】 come在这里是现在虚拟式(be型虚拟式)，故没有人称变化。当它用于时间从句时，可以不用连词。上句中的come winter=when winter comes.

1. She will be eighteen years old come Easter.

复活节到来时，她就十八岁了。

2. I almost think if I could do like you，drop everything and live out on the ground—but itmight be，come night I shouldn't like it. (Curme)

我简直想我如能学你的样，丢开一切，露宿在外面地上——但是，当夜晚降临时，我可能就不喜欢那样了。
