　　重点短语 重点句型 重点单词 ◆拓展延伸 Don’t mention it.别提了。 not to speak of=to say nothing of不用说,不用提 ◆词义辨析 1.not to mention在列举的几项后再加一项,前后是并列关系,多为肯定句中使用,相当于as well as。 Pollution has a negative effect on the health of everyone living in the city,not to mention the damage to the environment.=Pollution has a negative effect on the health of everyone living in the city,as well as the damage to the environment.污染对每个生活在城市里的人的健康都有不利影响,更不用说对环境的危害了。 2.let alone多用于否定句中,后加的一项是递进关系,是较之前的更加不可能的,目的是强调前一项不可能。 I never thought of it,let alone did I do it.我想都未曾想过这个,更谈不上去做了。

　　重点短语 重点句型 重点单词 ❶“疑问词+不定式”构成的复合结构 We started flying around the world and meanwhile,scientists figured out how to split the atom,previously thought to be the smallest particle of matter in the universe.我们开始在世界各地飞行,同时,科学家们发现了怎样分裂原子,而原子以前被认为是宇宙中最小的物质微粒。(教材原句P24) 句中how to split the atom为“疑问词+动词不定式”构成的复合结构。在英语中,“疑问词+动词不定式”的用法较为普遍,现在将其归纳如下: “疑问词+动词不定式”结构中的“疑问词”,包括疑问代词what,which,who和疑问副词when,how,where 等。这些疑问词和动词不定式一起构成了不定式短语,这种结构在句子中不能作谓语,可作主语、宾语或表语等。

　　重点短语 重点句型 重点单词 She didn’t know which bus to take.她不知乘哪路公共汽车。(作动词的宾语) We must first solve the problem of whom to serve.我们必须首先解决为谁服务的问题。(作介词的宾语补足语) When to start remains undecided.何时出发,尚未决定。(作主语) The difficulty for us is how to do the most of work with the least of money.于我们而言,困难是如何花最少的钱办最多的事。(作表语) 这种结构相当于一个名词性从句,不论它在句子中作什么成分,常常都可用同等成分的从句来替代。改为从句时只要在疑问词后面添加一个适当的主语并将不定式动词改为适当形式的谓语动词即可。所以上述几句可分别改成: She didn’t know which bus she should take. We must first solve the problem of whom we should serve. When we should start remains undecided. The difficulty is how we ought to do the most of work with the least of money.

　　重点短语 重点句型 重点单词 当这种结构作宾语时,常常置于show,find out,learn,teach,tell,advise,wonder,know,discuss,remember,forget,explain 等动词或动词短语之后。 The teacher showed us how to read a book.老师指导我们怎样读书。 You’d better find out where to put these pens.你最好了解一下应该把这些钢笔放在哪里。 ◆现学活用 用“疑问词+不定式”改写下列句子 1.How we should do it was discussed last night. →How to do it was discussed last night.  2.I didn’t know where I should go. →I didn’t know where to go.  3.The difficulty was how we should cross the river. →The difficulty for us was how to cross the river . 

　　重点短语 重点句型 重点单词 ❷过去分词作定语 We started flying around the world and meanwhile,scientists figured out how to split the atom,previously thought to be the smallest particle of matter in the universe.我们开始在世界各地飞行,同时,科学家们发现了怎样分裂原子,而原子以前被认为是宇宙中最小的物质微粒。(教材原句P24) 本句中“previously thought to be the smallest particle of matter in the universe”是过去分词短语在句中作定语,修饰先行词the atom,相当于定语从句which was previously thought to be the smallest particle of matter in the universe。 The building completed last month is a laboratory.上个月竣工的那个建筑物是实验室。 重点短语 重点句型 重点单词 ◆现学活用 用括号中所给词的适当形式填空 1.You cannot accept an opinion offered(offer) to you unless it is based on facts. 2.The first textbook written(write) for teaching English as a foreign language came out in the 16th century.

　　重点短语 重点句型 重点单词 ❸some of which引导定语从句 The ancient Chinese are associated with many important inventions,some of which have changed the world,and many of which,we still use today.古代中国人与许多重大发明息息相关。其中有些发明改变了世界,有些我们沿用至今。(教材原句P30) 本句中“some of which have changed the world,and many of which,we still use today.”是定语从句,在句中修饰先行词inventions,表示部分与整体的关系。 在英语中,如果两个句子被逗号隔开,并且中间没有连词,则这两个句子具有主次之分,其中居于次要地位的句子充当定语从句。同时,如果先行词与后面定语从句之间存在部分与整体的关系,则用关系词one/two/half/both/some/many/all...of which(whom)或of which(whom) one/two/half/both/some/many/all...引导定语从句。 The buses,most of which were already full,were surrounded by an angry crowd.大多数公共汽车都已经挤满了人,它们被愤怒的人群包围着。 重点短语 重点句型 重点单词 I bought a dozen eggs,six of which broke when I dropped the box.我买了一打鸡蛋,其中六个在我失手打掉了盒子时摔碎了。 ◆特别提醒 在表示所属关系时,可以用whose来代替of which/whom。 It was an agreement the details of which could not be altered.这是一项细节不可更改的协定。(the details of which=whose details) 重点短语 重点句型 重点单词 ◆现学活用 完成句子 1.去年他给我们讲了许多故事,其中大部分都非常感人。 He told us many stories last year,most of which were very moving.  2.我有几个好朋友,其中有两位是北京人。 I have some friends,two of whom come from Beijing.  3.他写了一本书,书名我忘了。 He’s written a book,the name of which/whose name I’ve forgotten. 

　　一、单句填空 1.(2015·江苏高考改编)Many wastes produced in the producing process are (harm) as well.  harmful。空格前是be动词,可知此处作表语,故用形容词。 2.(2015·四川高考改编)People have long puzzled how the Egyptians moved such huge rocks.  over。puzzle over 是固定搭配,意为“冥思苦想”。 3.He’s argued that America and its allies are putting too much(emphasize) on the military option.  emphasis。put emphasis on...为固定搭配,意为“把重点放在……”。

　　4.(2017·山东高考改编)Susan made clear to me that she wished to make a new life for herself.  it。句意:苏珊清楚地向我表明她希望为自己创造新的生活。分析句子结构可以看出,该句中包含一个that引导的从句,而且根据语境可知,that从句的内容就是苏珊向我表明的事情,所以后置的that从句实际上是made的真正宾语,故用形式宾语it指代that从句。 5.(2017·陕西高考改编)The manager wants to see changes in the company,and I am sure he will time.  in。句意:经理想要看到公司的改变,我确信他迟早会看到的。in time“及时;最后,迟早”,符合题意。 6.(2017·福建高考改编)Old-fashioned phones matter when wireless networks break in disasters.  down。句意:在灾难中,当无线网络出故障时,老式的电话意义重大。break down“停止转动,出故障”。

　　7.(2017·上海高考改编)—Was it by cutting down staff she saved the firm?  —No,it was by improving work efficiency. that。题干是强调句型的一般疑问式“Is/Was+it+被强调部分+that/who+其他”。句子强调的是方式状语by cutting down staff,用that构成强调句型的基本框架。 8.(2017·江西高考改编)We needn’t have bought so much food now Suzie won’t be with us for dinner.  that。句意:既然苏姿不和我们一起吃晚饭,那我们就没有必要买这么多食物。now that是固定搭配,意为“既然”,强调已知原因。 9.(2017·湖北高考改编)Whether the buildings in this area should be pulled has remained controversial;people are still looking for other possible solutions.  down。句意:这个地区的建筑是否应该被拆毁仍有争议;人们还在寻找其他可能的解决方案。pull down为固定短语,意为“拆毁”。 10.(2011·广东高考改编)Often,we try every way possible to avoid showing our(weak),which includes a lot of pretending.  weakness。空处有our修饰,故应填名词weakness“弱点”。

　　二、单元话题微写作 未来科技 根据提示,将以下句子连成一篇英语短文。 1.人们很难预测未来到底会是什么样子,但总是想弄明白。(predict;wonder about) 2.也许房子将配备轮子,能够在计算机的控制下自由地移动。(be equipped with) 3.也许随着机器人的功能越来越先进,我们的生活将越来越便捷。(convenient;advanced) 4.也许人们可以轻易品尝世界各地各种各样的美食,没有人会死于饥饿。(die of starvation)

　　It is hard to predict what exactly the future will be like,but people always wonder about it.Maybe some houses will be equipped with wheels so as to move freely under the control of the computer.Maybe robots will make life easier and more convenient with their advanced functions.Maybe people will be able to taste all kinds of food throughout the world easily and no one will die of starvation.
