... When we use a verb in -ing form more like a verb or an adjective, it is usually a present participle:. Anthony is fishing. I have a boring teacher. In this lesson, we will look at the use of verbs in the ~ing form ...

The ~ing form 作定语

现在分词可以单独作定语，也可以构成合成词作定语，但在更多的情况下是分词短语作定语，包括限定性和非限定性（用逗号与其他部分分开），在意义上相当于一个定语从句。现在分词作定语通常带有主动意义和未完成意义。例如：

The man following was obviously in a hurry。（现在分词单独作定语）

They acted just like a conquering army。（现在分词单独作定语）

Do you know the man standing over there by the motor car?（分词短语作限定性定语。）

Last night,we caught a thief stealing John's bike.（分词短语作限定性定语）

The name Nebraske comes from the Oto Indian word “ebrathka”.meaning flat water.（分词短语作非限定性定语）

The ~ing form 作状语

现在分词作状语表示主语在进行一动作的同时所进行的另一动作，它对谓语动词起修饰或陪衬的作用。这时要注意现在分词与其逻辑主语在时态和意义上的统一。例如：

Rushing out of the room, he has knocked down by a car.（作时间状语）

=When he rushed out of the room, he was hnocked down by a car.

Working harder, you will pass the entrance exam.（作条件状语）

=If you work harder, you will pass the entrance exam.

She sat at a window and read a book.（作伴随状语）

=She sat at a window and read a book.

=Because he had won the championship, he was awarded a million dollars.

=Even if I take a taxi, I will still be late for the meeting.

The road is under construction, thus causing the delay.（作结果状语）

=The road is under construction, and thus caused the delay.

注意，当现在分词作让步状语时，一般放在句首，常常由although, though, even if ,unless等连词引入；作结果状语时，一般放在句末，前面可so, thus, henc。
