If you feel it is difficult to understand what your Chinese friends are saying when communicating in daily life, it is time for you to spend much time in learning some useful oral Chinese expressions. Let’s take 都什么年代了as an example, which is a structure carries the tone of complaint or dissatisfaction. It is usually applied to emphasize the other party‘s idea or behaviors fall behind. As a result, if you want to express that someone does something out of fashion, you can use this pattern like 都什么年代了，你怎么还想一家三代住一块儿啊？

Many of those frequently used oral expressions are the contents can’t be learned in volunteer program in China. For the structure都什么时候了, you need to know it is used to show it can’t be delayed any more. It carries the tone of criticism and complaint. The sentence you often hear might be 都什么时候了，你还不起床！

Let’s move our attention to the language point 都是… which is to emphasize somebody should take the responsibility of doing something, equal to 都是…的责任. When using this structure into the actual sentence, learners need to know it is more often used in the second person and third person, carrying the tone of complaint. For instance, A: 我听说这种大衣降价了. B:都是你，当初非要我马上买，这不该听你的.

When you hear Chinese people say the sentences with the structure 多少也得… like今天是你大喜的日子，多少也得喝点儿. You need to know it is used to mean the number can be more or less, but it should be done. Sometimes, 也can be omitted and sometimes it is used to force the others to do something or has the tone of having no choice.

Of course, another important structure that the students should know when they learn Mandarin Chinese is 多管闲事, which is frequently applied to show that somebody should not charge something that is out of his business. The sentence 你就别多管闲事了carries the tone of scolding.
