　　感官動(dòng)詞 + doing/to do

　　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.
