　　如何写好简单句(8) 1．形容词在句中可以作定语、表语和补语，还可以作状语，具有副词的功能。形容词作状语一般用逗号隔开，根据情况可位于句首、句末，也可位于句中，相当于一个从句。 (1)形容词或形容词短语作状语，放在句首，作原因状语。 Angry at the girl oversleeping，Mr. Green went down to wake her up. (＝Mr. Green went down to wake her up because he was angry with her for oversleeping.) 格林先生下去叫醒女孩是因为她睡过了头而惹恼了他。 (2)形容词或形容词短语作状语，放在句末，表主语的状态。 Crusoe stared at the footprint，full of fear.(＝Crusoe stared at the footprint and he was full of fear.) 克鲁索两眼盯着脚印看，满心恐惧。 2．分词作状语在英语中出现频率极高。一方面，使句式多样化；另一方面，促使句子更简练。 (1)分词短语作状语放在句首，可表原因、时间、条件等。 Hearing the sad news，Sandy couldn't help crying.

　　听到这悲惨的消息，Sandy忍不住哭起来。 (分词短语表原因) Given more time，I could do it much better. 如果时间更充分，我会做得好得多。(分词短语表条件)

　　(2)分词短语作状语放在句末，可表伴随、 结果等。 They worked hard together，pushing the bus slowly forward. 他们一起用力把车子慢慢向前推。(分词短语表伴随动作) He died early，leaving his wife nothing but grief and debt. 他英年早逝，什么也没有留给妻子，除了悲伤和债务。(分词短语表结果) 3．介词短语在句中可作定语、状语、表语， 它的位置非常灵活，可以在句首、句中、句末。恰当使用介词短语可使简单句表达更多信息，也使句子结构更加巧妙，显示考生不俗的表达能力。

　　(1)Instead of giving us answers immediately，he encourages us to think by ourselves. 他鼓励我们独立思考，而不是立刻把答案告诉我们。

　　(2)In spite of all these difficulties，he managed to accomplish the project on time. 尽管有种种困难， 他还是设法按时完成了这个工程。 4．同位语也可使众多关于同一个人或同一事物的信息简单化，使句子结构简单明了。如： Mr. Zhang is a famous expert. He teaches us chemistry this year. → Mr. Zhang，a famous expert，teaches us chemistry this year.(著名专家张先生今年教我们化学。) 5．主语＋动词(谓语)＋it＋名词/形容词＋(for sb.) to do sth. We thought it important (for you) to read the contract carefully before you sign it. 我们认为在签字前你要仔细阅读合同条款，这很重要。 ◆ 活学活用 1．用分词短语改写下列句子 (1)Zhongshan University was located in Guangzhou，Guangdong province.
