When foreign students who just learn to speak Chinese talk with Chinese people, they often feel confused by some sentence structures used by them. For example, you may hear 我不想和他住一个房间，抽烟不说，睡觉还打呼噜, which is one example of the structure A 不说，还 B. When we use it, we usually intend to indicate that there is B in addition to what is said in A. In the above sentence, the one is not only 抽烟, but also 打呼噜.
After understanding the meaning, you should know how to apply it to the daily conversation. It is simple to use because you can just replace A and B with the part what you want to say like 周末咱们去温泉度假村吧，能洗温泉不说，还能钓鱼呢. One point that the students in Chinese school in China should know is that sometimes 不说can be replaced by不算. But it usually refers to something unpleasant. We can say 昨天我家被盗了，小偷偷了钱还不算，还打坏了不少东西.
If you want to emphasize the degree of one thing is very high so that reaching the extreme, you can say sentences of the pattern A得不能再A了. For example, 这孩子胖得不能再胖了，该让他减减肥了. The part A is usually an adjective. The sentences of such type are exaggerating. Sometimes, it is also used for irony like in the dialogue: 甲：我这么做有什么不好吗？乙：好，真是好得不能再好了.
If you meet sentences like A 的 A，B 的 B when you learn Mandarin in China, you should know it refers to the fact that some are in this case while others are in that case. When combined, they can stand for the whole. For instance, 晚会上，大家说的说，笑的笑，非常热闹. Generally speaking, A and B are adjectives, verbs or verbal phrases.
