　　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。
