语法点一
1．作时间状语时，相当于一个时间状语从句。其前面可加when, while 或before等词。 Putting on his clothes, Bill went out in a hurry. 穿上衣服后，比尔匆忙离开了。
While waiting at the dentist's, I read a short story. 在牙医诊所候诊时我读了一篇短篇小说。 2．作条件状语时，相当于一个条件状语从句。 Reading carefully, you'll learn something new. ＝If you read carefully, you'll learn something new. 仔细读，你就会学到新东西。
3．作原因状语时，一般可改写成as或because引导的原因状语从句。 Being tired, he couldn't walk any further. ＝As he was tired, he couldn't walk any further. 由于累，他再也走不动了。
4．作让步状语时，其前可加上although, though, even if/though等词。 Knowing all this, they made me pay for the damage. 尽管知道了一切情况，他们还是要我赔偿损失。 Having failed many times, he didn't lose heart. 尽管失败了许多次，他没有灰心。
5．作结果状语时，其前可加thereby, thus, therefore等词。
The book sold more than 500,000 copies a year, making it one of the bestsellers at that time.
那本书一年销售五十多万册，使它成为当时的畅销书之一。 The fire lasted nearly a month, leaving nothing valuable. 大火持续了近一个月，没剩下什么值钱的东西。
[名师点津] 现在分词作结果状语表示自然而然的结果。动词不定式位于句末，常与only, never,
动词ing形式作状语 not等副词连用，表示出乎意料的结果。
The old lady hurried to the market, only to find her money stolen on the bus. 老太太匆匆赶到市场，结果却发现自己的钱在公共汽车上被偷了。 6．作方式或伴随状语。
用来说明动作发生的背景或状况。一般情况下，现在分词的动作与谓语动词的动作同时进行，其动作发出者就是句子的主语。谓语动词是主要动作，分词是陪衬动作，伴随状语或方式状语位于句首、句中或句末均可。
They all stood there, watching closely when the magician performed the magic tricks. 当那个魔术师表演魔术时他们都站在那儿，仔细地看着。
