有一项是符合题目要求的)

She was doing her homeworks one Sunday morning… 81. ______

［简析］homeworks→homework。homework 为不可数名词。

2. 名词“ 数” 方面的错误

① (2008 宁夏、海南卷)

More than 1000 painting will be on show, and high school students and teachers from all the eight districts will come to the event.

［简析］painting→paintings。painting 前有表示复数意义的数词1000 修饰，因此应改为复数形式paintings。

② (2004 福建卷)

When you come, you can stay with ourselves… 83. ______

［简析］ourselves→us。由于主句的主语和宾语不是同一人，宾语不应用反身代词，而应用宾格人称代词。

② (2004 湖北卷)

John Brown is a London taxi driver who love going to the theatre. 76. ______

［简析］love→loves。主语a London taxi driver 为单数名词，因此复数动词love 应改为其单数形式。

2) 代词指代错误

主要考查人称代词混用错误和人称代词属格混用错误，一般通过分析上下文弄清人称代词的正确指代或分析人称代词的功能可以发现并改正这类错误。一般情况下，主格人称代词多作主语，宾格人称代词多作宾语，形容词性物主代词须作定语，名词性物主代词可作主语、宾语或表语，反身代词可作宾语或同位语。如：

① (2008 全国卷Ⅱ )

I should be able to tell visitors about our history and culture and show them their great

One day, while my friend and I was traveling through Germany, we were very hungry but we only had a little money. 76. ______

［简析］was→were。主语my friend and I 为复数概念，因此单数动词was 应改为复数形式were。

② (2008 陕西卷)

1.“一致性”方面的错误

高考英语短文改错题在主谓一致这一语法角度主要设置动词单复数形式混用错误，如：主语为复数名词或代词时动词用单数，主语为单数名词或代词时动词却用复数。同学们应分析主语单复数与动词单复数形式是否一致，从而发现并改正主谓一致错误。如：
