典型例題
1）They knew her very well. They had seen her ___ up from childhood.　
　 A. grow　 B. grew　 C. was growing　 D. to grow
　 答案：A。因題意為，他們看著她長(zhǎng)大，因此強(qiáng)調(diào)的是成長(zhǎng)的過程，而非正在長(zhǎng)的動(dòng)作，因此用see sb do sth 的句型。

2）The missing boy was last seen ___ near the river.　
　A. playing　 B. to be playing　　C. play　　D. to play
　答案A. 本題強(qiáng)調(diào)其動(dòng)作，正在河邊玩，應(yīng)此用see sb. doing sth句型。
