Can't you come in and have tea now, Peter?
Not yet. I must water the garden first. Do you have to water it now? I'm afraid I must. Look at it! It's terribly dry. What a nuisance! Last summer it was very dry, too. Don't you remember? I had to water it every day. Well, I'll have tea by myself. That was quick! Have you finished already? Yes. Look out of the window. It's raining! That means You don't need to water the garden. That was a pleasant surprise. It means I can have tea, instead.

彼得，你现在能进来喝茶吗？
还不能。 我得先给花园浇水。 你一定得现在浇吗？ 恐怕我得现在浇。 你看看！干得厉害。 真讨厌！ 去年夏天也是干得很。 你记得了吗？ 我不得不每天浇水。 好吧，我一个喝茶了。 好快啊！ 你已经浇完了？ 是的。你看看窗外。 下雨了！ 这就是就是说，你不必给花园浇水了。 这是意想不能的好事。 这意味着我反倒可以喝茶了。
