The most advanced technology is useless if farmers don't trust it.

如果我结婚，我想深处婚姻之中。

Sometimes we get sad about things and we don’t like to tell other people that we are sad about them. We like to keep it a secret. Or sometimes, we are sad but we really don’t know why we are sad, so we say we aren’t sad but we really are.

我不害怕说出我的想法。
