I am on a diet now, so would you please bring me a fruit salad.

我正在节食，能给我来份水果沙拉吗?

Botanically the tomato is a fruit. Do you expect to find tomatoes in a fruit salad? Most probably not. But the ubiquitous tomato will appear in every vegetable salad.

在植物学上，番茄是一种水果。您希望在水果沙拉中找到西红柿吗？很可能不是。但是无处不在的西红柿会出现在每一种蔬菜沙拉中。
