例1（2006浙江高考）The company had about 20 notebook computers but only one-third__________ used regularly. Now we have 60 working all day long.

A. is　　　　　　　     B. are　　　　　　C. was　　　　　　D. were

思路分析:本题考查主谓一致及动词时态，当分数、百分数作主语时，要根据后面的名词来决定其谓语动词的单复数。此处one-third 指的是one-third of the notebook computers，因此谓语动词用复数，且句子时态应用过去时。

答案:D

深化升华 当分数、百分数修饰population并作句子主语时，通常谓动用复数，即看作是people(许多人)的概念，而不是看作一个人口数目。

例2(2006辽宁高考)The father as well as his three children __________ skating on the frozen river every Sunday afternoon in winter.

A. is going                     B. go                     C. goes                 D. are going

思路分析:本题考查主谓一致，A as well as B短语结构中as well as B属修饰部分，中心主语为A，即本句的中心主语是the father，可知谓语动词应用单数；由时间状语every Sunday afternoon in winter可知用一般现在时。
