8、作结果状语。通常放在句末,用逗号与前面的部分隔开;有时为了突出结果,其前可带thus。She was so angry that she threw the plates on the floor,breaking them into pieces(=and broke them into pieces).翻译 她是如此生气,以至于把盘子扔在地上,摔得粉碎。5.作条件状语。相当于if引导的条件状语从句。Working hard(=If you work hard),youll succeed sooner or later.翻译 努力学习,你迟早会成功的。6.表示方式或伴随情况。这种用法可以用
