短文改错的名词考点主要涉及名词的单复数问题，即在该用复数的地方误用其单数，或在该用单数的地方误用其复数。

真题单句归纳：

(1) There are branch library in many villages. (library 改为libraries，因其前的谓语are为复数) (全国卷)

(2) Today I visited the Smiths — my first time visit to an American family.(去掉time，因first 已含有“次”的意思) (全国卷)

(3) …so that I‘ll get good marks in all my subject. (subject 改为subjects，请注意前面的 all) (全国卷)

(4) You can find all kinds of information in just a few minute on theInternet. (minute改为minutes，因为a few后面的名词一定是复数) (广西卷)

(5) Without enough knowledges， you can never teach well.(knowledges改为knowledge，因 knowledge是不可数名词，没有复数形式) (湖北卷)
