After students have studied Chinese for a period of time, they should be able to read independently. On the contrary, we can also study Chinese language in the reading. In the following parts, some sentences will be given, among which one is incorrect. Students should find out the incorrect ones according to what they have learned.

The first example for those who learn Mandarin is as follow:
A 恐龙身高达九米，比长颈鹿还要高一倍，这需要多高的血压啊！
B 除非你根本没有认真复习，否则考试结果不可能及格。
C 看着她低头咬着嘴唇默默垂泪，梁萧的眼睛不由得也濡湿了。
D 客家人的服饰图案朴实精美而又寓意深刻，这也是南迁客家人与原住少数民族交流融合的结果。

If the foreigners who have come to learn Chinese in China for a long time, they can find the mistakes when they read the second sentence. The meanings of the two parts are in contradiction. The structure “除非X，否则Y” means the condition “Y” will not happen. Therefore, the “不” in “不及格” should be removed.

When doing such exercise, those who study in China should be carefully and pay more attention to the details. Let’s see another group of sentences:
A 李贵这小子精得很，早已闻到了他俩之间有一股火药味。
B 老季一屁股坐在了小沙发上，闭了一会儿眼，脑子里五光十色的想法如潮水般涌出来。
C 除非对方是艺术内行或什么大人物，他在构思和手法才讲究一些。
D 恐龙属于爬行动物，对于后来地球动物的形成有重要影响，因此研究恐龙的意义十分重大。

From the first sight, it is difficult for students who just come to learn Mandarin in China to realize the mistakes even they understand the meanings of these sentences. In the latter part of the second part, it emphasizes the aspects of “构思和手法”. In Chinese, we want to describe a certain aspect of things, we should add “方面”. So it should be “在构思和手法方面”.

Generally speaking, the sentences appear in this kind of practice are all representative. Therefore, students who learn Chinese language in China should read more repeatedly after correcting them. They can also read the other sentences repeatedly.

From the two exercises above, we can see that if we want to find out the mistakes in the sentences, we should understand the meanings firstly and then pay attention to the details.
