Find 的特殊用法：
Find 后可用分詞做賓補(bǔ)，或先加形式賓語(yǔ)，再加形容詞，最后加帶to 的動(dòng)詞不定式。find后也可帶一個(gè)從句。此類動(dòng)詞還有g(shù)et，have。
I found him lying on the ground.
I found it important to learn.
I found that to learn English is important.
典型例題:

A. lying B. lie C. lay D. laying
答案：A.find的賓語(yǔ)后面，用分詞或分詞短語(yǔ)，起賓語(yǔ)補(bǔ)足語(yǔ)作用。現(xiàn)在分詞表達(dá)主動(dòng)，也表達(dá)正在進(jìn)行，過(guò)去分詞表達(dá)被動(dòng)。
) to + be 的不定式結(jié)構(gòu)，作補(bǔ)語(yǔ)的動(dòng)詞。
