假如

想象一下，假如你有一台时光机。

xiǎng xiàng yī xià， jiǎ rú nǐ yǒu yī tái shí guāng jī。

Imagine that you have a time machine.

假如你没有这个程序，你现在就可以去下载。

jiǎ rú nǐ méi yǒu zhè ge chéng xù， nǐ xiàn zài jiù kě yǐ qù xià zǎi。

If you do not have this program, you can download it now.

假如你有1000美元，你会用它做什么呢？

jiǎ rú nǐ yǒu 1 0 0 0 měi yuán， nǐ huì yòng tā zuò shén me ne？

Suppose you had a thousand dollars, what would you do with it?
