It has been a top concern for foreign learners to find out how to study Chinese better. As a matter of fact, reading more after learning the language points is an effective way for Chinese language learning. In the following parts, the application of words 下去、起来、出来and进去will be practiced with explanation and actual examples.

First of all, the learners need to know the basic meanings of those four words, all of which can be used to show the change of certain actions. But they have different explanations when being used in different sentences and situations. Let’s take 下去as an example. In the sentence 就是再难，我们实验也要做下去, 下去carries the meaning of continuing to do something. The whole sentence means to carry on experiment no matter how much difficulty we will meet.

For some examples, you can make sentences like 你不捡球，这场球就别想打下去and世界上任何话题他都接得下去. According to these sentences, we can summarize that 下去means to make something continue to develop. When you study as volunteer in China, you can hear a lot that Chinese people say 起. It is often used to indicate the development of certain things from good to better. For example, 春节一过，天气就一天天暖和起来了, 起来here means the weather is getting warmer and warmer.

Let‘s move the attention to the word 出来, which has the tone that something is showed or appear. For instance, 从他结结巴巴的汉语，我听出来他是个外国人, the latter part of which means I can tell that he is a foreigner, that is to say, the feature of the foreigner is showed. You can make sentence like 他的情绪一般不大会从脸上露出来.

The last but not least word you need to learn is进去, with the literal meaning of enter or go inside. For example, in the sentence 我警告了她好几次，可是她根本听不进去, the latter part means do not hear what I said.
