1.现在分词作定语时很多，有时单独作定语放在所修饰的词前面(a)，有时引起短语放在所修饰词的后面(b)：
a. He is a promising young man.
他足个很有培养前途的青年。
It is a fascinating city.
它是一座迷人的城市。
They are visiting in a neighboring town.
他们在邻近的一座城市访问。
He was one of the leading composers of the time.
他是那时最卓越的作曲家之一。
b. Anna drew a girl who was standing on her hands.
安娜画了一个倒立的姑娘。
There's someone knocking at the door.
有人敲门。
We built a high way leading (which led) into the mountains.
他们修了一条通往山里的公路。
We met a group of children (who were) returning from school.
我们碰到一群放学回来的孩了。
2.现在分词作定语相当于一个定语从句,即使单独的现在分词也如此：
a promising Young man = a young man who is promising
这也是作定语的动名词和现在分词的区别。现在分词作定语时多表示所修饰名词的动作，常可改为一个定语从句：
flying fish (=a fish that can fly) 飞鱼
everlasting friendship (=friendship that lasts forever) 永恒的友谊
working people (=people who work) 劳动人民
而动名词作定语时却没有这种情况，如：
sleeping car (=a car for passengers to sleep in) 卧车
working method (=method of working) 工作方法
reading room (=a room for people to read in) 阅览室
另外，现在分词还可构成合成形容词，如：
hard-working people (=people who work hard) 勤劳的人民
oil-bearing crops (=crops that bear oil) 油料作物
good-looking 貌美的
