11、nything special to express my thanks.书面表达黄山为“三山五岳”中“三山”之一，位于我国安徽省境内。黄山有 72 峰，风景区自然景观秀丽，奇松、怪石、云海、温泉素称黄山“四绝” ，令海内外游人叹为观止。请写一篇 100120 词的短文来介绍一下黄山。参考词汇：peak 山峰；irregular 不规则的_动词不定式和现在分词作结果状语的不同用法：动词不定式作结果状语时，表示出乎意料的结果。现在分词作结果状语多表示顺其自然的结果，即主句和结果之间有一定的因果关系。We hurried to the station only to be told that th
12、e train had left.我们急匆匆赶到车站，结果被告知火车已开走了。The fire lasted a whole night， causing great damage.大火持续了一整夜，造成了巨大损失。课时作业答案解析Period Four Grammar & Writing.1.A 句意为：这位退休的老人把自己的大多数积蓄捐献给了在玉树地震中损坏的那所学校，从而使得学生们重新回到了教室。2D 句意为；他有一个非常美好的童年，那时他跟着他的妈妈周游世界。从句意看他和旅游之间为主动关系，又因为 He had a wonderful childhood 是一个完整的句子，故选 D 项
13、。3C 句意为：南方天降大雨，导致许多省份出现了严重的水灾。动词的现在分词形式在句中作结果状语，强调主句动作发生后所导致的结果。having caused 体现的动作先于主句动作发生；to cause 说明该动作发生在将来，与事实不符；serious和 several 这两个形容词都说明结果已经出现。故选项 C 正确。4B 句意为：律师全神贯注地听着，尽量不漏掉任何一个要点。空格处应是伴随状语，与主句动作 listen 同时发生，应用现在分词形式，排除 C、D 两项；A 项是现在分词 trying 的否定形式，意为“不努力”；B 项意为“努力不”。由句意知，应选 B 项。5C 句意为：这位女士
14、在各家商店逛来逛去，时刻注意着廉价商品。keeping an eye out for bargains 为现在分词短语作伴随状语，其逻辑主语为 the lady。6B 本题考查现在分词的完成式作状语，表示在谓语动作之前发生的动作，其否定形式是在其前面加 not。 7B hope 和逻辑主语是主谓关系，故用现在分词作伴随状语。8C 本题考查非谓语动词作状语。wait 发生在谓语动作之前且和逻辑主语是主谓关系。9D leaving 作伴随状语，第二空作宾语补足语，lie 和 book 是主谓关系，故用lying。10B 本题考查动名词作介词的宾语，not 要放在动名词的前面。11D 此处为非谓语动
15、词作状语，与句子主语 he 之间为被动关系，故可排除B、C 两项。根据前后句的逻辑关系可知，非谓语动词应用完成时态表示动作发生在句子谓语动词 understood 之前。12D 本题考查分词的逻辑主语必须与句子的主语保持一致。四个选项中只有D 项的主语能作 finding 的逻辑主语。13C 句意为：由于天气很好，孩子们去了公园。后一部分为完整的句子，前后两部分无连接词，且前后两部分主语不一致，所以前一部分是独立主格结构，故选C 项。14D 句意为：因为不知道关于那件意外事故的任何情况，他照常去上班了。句子主语 he 与 know 是主谓关系，故用现在分词作原因状语；非谓语动词的否定形式应在非
16、谓语动词前加 not。15B 句意为：他在忙着写一个故事，只是偶尔停下来抽支烟。此处应为现在分词短语作伴随状语，表示与 write 伴随的动作。A 项通常作目的状语和结果状语。 .1.Having finished 2.Having been warned 3.It being sunny 4.Thinking it over 5.Not knowing.1.Having brushed his teeth，Mr.Brown came downstairs for breakfast. 2.Travelling by train，we visited a number of cities. 3
