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(guò)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。
