Grammar is important in any one language because the grammatical rules standardize the expression forms so that everyone can understand the meaning expressed. During the process when Chinese teachers teach Mandarin language, they often list some important grammar points after learning a certain lesson. For example, the pattern 对…来说 is a structure often used to indicate to see from the perspective of certain person or thing. The point needs students’ attention is that it is usually put at the beginning of the sentence or in the middle of sentence like 对日本人来说，写汉字并不困难. Sometimes, it can be used as 对于…来说and对…来说.

Another grammar point that the foreign students need to master is A + 所 + verb + 的 + B like in the sentence 我们所了解的情况还不够详细. Here, 所is an auxiliary word often used before transitive verb, together with的 to modify the words or phrases behind it so that the whole structure forms a nominal composition. A and B are the subject an object of the verb,. In certain language environment, B which is modified by 所…, can be omitted. In addition, this pattern is more often used in written form. For instance, 这就是战争所造成的严重后果.

When studying in qualified Mandarin program, many students may have heard and seen many sentences with the pattern 拿…来说like 这个地方的生活很不方便，拿打电话来说，常常要道15公里以外的县城里去打. According to the given example, we can see that this structure is used to lead to a typical example to illustrate the conditions mentioned before.

For the Chinese structure A被B所 + verb, it is a very formal expression forms of passive sentence. For example, 我们被江上动听的琴声所吸引，忘记了开船出发. The words after 所are usually disyllabic words and can’t take other constitutions. However, if the words are monosyllabic words, the whole sentence has strong style of ancient Chinese language.
