If you want to speak a full sentence with complete meaning, you should know some grammar knowledge. For example, the structure 就是…也…is often used to indicate assumption and concession. The former part is often the assumed or extreme conditions while the latter indicates that the result or conclusion is free from the effect of such conditions. For example, 会议上有了它，就是再空洞的会议也会显得主题正确，内容充实. However, the point that the students who study in Chinese learning programs should know is that if the latter clause takes subject, 也should be placed after the subject like 就是明天下雨，足球赛也会照常进行.

Another common and important structure is “A…. B 则…” in the sentence like 精力过人的一类，只管自己发球，不管你接得住接不住，消极的一类则相反，难得接你一球两球. This pattern is applied to indicate the comparison between the former and the latter, carrying a slight tone of transition. 则here is an adverb used in the second clause. Sometimes, the conjunctive 而is used to collocate with 则. For instance, 一般来说，北方人喜欢吃面食，而南方人则喜欢制米饭.

In the sentence不管对手是积极还是消极，反正该你捡球, 不管…. 反正… has the function of emphasizing that the result or conclusion will never be changed in any cases. The phrases “verb不verb”, “adjective不adjective” and “是A还是B” are often placed after 不管. Students who learn Chinese online free should also know 反正is adverb often used before subject. For example, 不管别人来不来，反正你得来.

至于is also important for those who are leaning Mandarin Chinese to learn. Usually, the preposition 至于if to introduce another topic, being placed at the beginning of the clause. And the part after it is the topic. We can say下个月我们要去农村实习，至于哪一天去，现在还没确定.
