注意：現(xiàn)在分詞作定語時表示動作正在進(jìn)行或與謂語動詞所表示的動作幾乎同時發(fā)生.如果兩個動作有先有后,一般不能用現(xiàn)在分詞作定語,而要用定語從句.如：
The teacher criticized the student who had broken the window.
①現(xiàn)在分詞作定語
A．現(xiàn)在分詞作定前置時靜感強(qiáng),而后置的現(xiàn)在分詞動感強(qiáng).如：
The working people are the wisest.
The farmers working here are very busy.
能前置的現(xiàn)在分詞為數(shù)不太多,常見的大都是已被形容詞化了的現(xiàn)在分詞,前常有程度副詞,有些現(xiàn)在分詞甚至還有比較等級.如：
I have brought very exciting news to you.
This is the most exciting story that I have ever read.
B．有些現(xiàn)在分詞作定語時表示正在發(fā)生的動作,這些現(xiàn)在分詞若改為定語從句宜用進(jìn)行時態(tài).如：
Did you tell the children playing there not to make any noise
Did you tell the children who were playing there not to make any noise
The American president visiting China now will return on Saturday.
The American president who is visiting China now will return on Saturday.
有些現(xiàn)在分詞作定語時表示經(jīng)常性動作或現(xiàn)在（或當(dāng)時）的狀態(tài).此類現(xiàn)在人詞若改為定語從句宜用一般時態(tài),而不宜用進(jìn)行時態(tài).如：They stayed at a hotel standing (which stood) by the lake.
The temple standing (that stood) on top of the hill was built in the Ming Dynasty.
