我在网上学的。

Wǒ zài wǎngshàng xué de.

I learned it online.

如果她可以在网上工作，那么她可以在家工作。

Rúguǒ tā kěyǐ zài wǎngshàng gōngzuò, nàme tā kěyǐ zài jiā gōngzuò.

If she can work online, then she can work at home.

虽然在网上买衣服的时候，你不能试穿，但是，买回来以后，你可以试穿啊。

Suīrán zài wǎngshàng mǎi yīfu de shíhou, nǐ bùnéng shìchuān, dànshì, mǎi huílái yǐhòu, nǐ kěyǐ shìchuān a.

Although when you buy clothing online you can't try it out, you can try it on after you buy it.
