I don't know why she didn't go to school yesterday. 三. 动词不定式的省略 1.当不定式在形容词afraid, anxious, eager, glad, happy, ready, willing等后作状语时,to后的内容常省略。 You can't force him to answer the question if he's not ready to (answer the question). 如果他不愿意回答这个问题,你不能强迫他。 2.某些使役动词如:make, let, have等和感官动词如:see, watch, notice, observe, hear等后面作宾补的不定式须省略to,但若这些动词用于被动语态,则to不省略。 We often hear her sing an English song in the classroom. →She is often heard to sing an English song in the classroom.(被动语态) 我们经常听见她在教室里唱英语歌。 3.并列的不定式可以省略后面的不定式符号to。但若两个不定式之间表示对比关系时,不省略to。 ①He likes to swim more than (to) skate. 比起溜冰他更喜欢游泳。 ②He believes it important to study rather than to play computer games.(比较) 他认为最重要的是学习而不是玩电脑游戏。 4.当不定式在某些动词后作宾语时,常可省略。常见的动词有agree, afford, expect, forget, hope, know, manage, pretend, remember, refuse, want, wish, would like等。 I asked him to see the film, but he didn't want to (see the film). 我请他看电影,但是他不想去。 5.介词but, except(除了)前有实义动词do的具体形式时,后面的不定式不带to。 All he could do was nothing but wait and see. 他所能做的只有等等看。 6.当不定式在be going to, be able to, have to, ought to, used to后作复合谓语时,不定式可省略。 They don't go shopping as much as they used to (go shopping). 他们不像过去那样经常去购物了。 注意:(1)省略的不定式内容若含有作助动词用的have或be的任何形式时,to后要保留原形的have或be。 (2)类似这样用法的还有动词短语be going to, be about to, be supposed to, have to, used to及形容词glad, happy, pleased, delighted等。 ①He didn't come, but he ought to have (come). 他没来,但他应该来。 ②—Are you a farmer —No, but I used to be (a farmer). ——你是个农民吗? ——不是,但我过去是。 【跟踪典例】单句改错 ①There were so many cars held up by the heavy rain on the road that we had no alternative but wait. ②We can do nothing but to give up. ③He was noticed leave the office. ④The city now is much noisier than it used to. ⑤My mother wouldn't let me to go to see the film. 【答案】 ①but后加to ②去掉to ③noticed后加to ④to后加be ⑤去掉第一个to 【巩固练习】 Ⅰ. 单句语法填空 1.

On its sides 2 (print) the words TRACKER DOG and a telephone number. Yes, the passenger in the blue truck is a dog that 3 (be) used to find lost things or follow the tracks of persons and animals. Within seven years, the dog and his 4 (own) Anderson have found lost things worth nearly $400, 000, among 5 are watches, jewelry, money, cows, pigs, and other dogs. Of course, the secret of the dog is his sensitive nose. Each year the dog and Anderson answer about 700 calls 6 help. Four out of five times they find what they are asked to look for. Whenever the phone rings at Anderson’s house, the dog is 7 (immediate) excited. He quickly runs to the truck, eager to be off in search of the 8 (lose). On the way, Anderson repeats again and again the names of 9 they are looking for. So by the time they arrive, the dog is ready 10 (get) to work. He circles here and there until he picks up the smell of an object in a place where it doesn’t belong. 答案: 本文讲述了国家公园的来历和作用:1916年,美国建立了世界上第一个国家公园系统,从那时起,它就成为其他国家更好地保护环境和让人们享受大自然的典范. 1. 考查状语从句的省略。分析句子可知,as if引导状语从句,此处强调“好像正在听他的指令”,应用现在进行时is listening,因为状语从句的主语与句子主语一致,此处省略了主语,所以此处be动词也省略,故填listening。 2. 考查动词时态、语态和主谓一致。根据上文Whenever the truck goes by, the people of Funen turn and stare,可知时态为一般现在时;主语its sides与动词print之间是被动关系,故用被动语态,its sides是可数名词复数,故be动词应用are,故填are printed。 3. 考查时态和主谓一致。根据空前the passenger in the blue truck is a dog可知,时态为一般现在时;that ______(be) used to find lost things or follow the tracks of persons and animals是一个定语从句,that指代先行词a dog,表示单数,所以谓语动词用单数形式,故填is。 4. 考查名词。根据空前的形容词性物主代词his可知,空处应填一个名词,此处指它的主人, 用owner,根据空后Anderson可知,该空应填名词单数,故填owner。 5. 考查非限制性定语从句。此处为介词 + 关系代词引导的非限制性定语从句, 先行词是物, 只能用关系代词which。故填which。 6. 考查固定用法。calls for help呼救, 寻求帮助, 是固定用法。故填for。 7. 考查副词。修饰形容词excited应用副词形式, 故填immediately。 8. 考查形容词。句意是说它渴望离开去寻找丢失的物品。表示“丢失的物品”要用the lost,故填lost。 9. 考查宾语从句。分析句子可知,空处引导一个宾语从句,作介词of的宾语,引导词在从句中作宾语,表示“寻找的东西”,应用what引导,故填what。 10. 考查固定短语。be ready to do sth. 是固定短语,意为“准备好做某事”,故填to get。 【要点回顾】 【温故知新】 I. 阅读理解 A Now, cities large and small often have remains of earlier historic streets and sidewalk pavements(人行道).Yet they often go unprotected even when they may be older than neighbouring historic buildings that have enjoyed protection for tens of years. There are many reasons to protect historic pavements - culture value, economics, environmental benefits and public safety. Pavements represented an important step in the modernization of city environments in the 19th century. Before the laying of pavement, streets of dirt caused many problems to citizens, especially in wet weather when they became muddy(泥泞的), which limited the movement of people and vehicles. To solve the problem, cities experimented with a wide range of materials in an attempt to balance durability(耐用性), economics, sources of materials and noise considerations. The earliest pavement in many cities were cobblestones-naturally rounded stones. They were cheap and durable,but rough and noisy. Loose stone pavements were cheap and smooth, but not very durable. Wood also appeared in the 1850s as a popular option-smooth, quiet and affordable,but not very durable. In many cities and towns, brick(砖)streets are the only historic pavements that have survived. This fact covers up the truth of pavement experimentation between the 1850s and 1920s, when a city could use up to a dozen different paving materials at the same time! Indeed, each city developed a unique "pavement identity" in the materials chosen and the way they were laid. It is easy to think of the past when seeing historic pavements, as recalling "old world" city qualities. However, they are more similar to the early high buildings and parks-important city features that showed the modernization of the city. At a time when cities are becoming increasingly similar, such pavements also help define an important sense of place. 1. What is the present situation of historic pavements A. Failing to represent modem environments. B. Failing to receive protection they should get. C. Being brought back to its former glory. D. Being highly valued as cultural buildings. 2. Why was the first pavement built in history A. To help develop the local economy. B. To prevent earth from being washed away. C. To limit the movement of people and vehicles. D. To bring convenience to citizens' life. 3. What is mainly talked about in Paragraphs 4-6 A. Popularity of different paving materials. B. Different experiments on city identity. C. Advantages and disadvantages of stone pavements. D. Development of pavements of different materials. 4. What does the writer want to express about historic pavements in the last paragraph A. They are similar to tall buildings. B. They make cities appear similar. C. They are unique of a particular place. D. They represent the modernization of today's city. B There are many ways to deal with the plastic pollution. Tom Szaky's way may be one of the bravest. He has gone back to an old way-using reusable containers. The idea was used in the last century. It was introduced to the world by Coca-Cola in the early 1920s, when Coke was sold in expensive glass bottles that needed returning. They asked for two cents, about 40 percent of the full cost of the soft drink, and got about 98 percent of their bottles back, to be reused 40 or 50 times. Bottle deposit programs remain one of the most effective methods. Ten months ago, Szaky started Loop, an online delivery service that uses strong reusable containers. The biggest part of his risk is that Loop pushes far beyond the common reusable bottles. From food packaging to washing powder packaging,the containers are in different sizes and made from different materials. One of his products is Haagen-Dazs ice cream that is packed inside a special box to keep the ice cream from melting. 17 years ago, Szaky founded TerraCycle, a small waste management company. He thought up a way to deal with plastics, cigarette wastes, and a long list of other wastes. Gradually, he became more interested in thinking of how to recycle different kinds of waste in the best way. Loop is part of the reappearance of the reusable packaging as a best choice to plastic waste. The food and drink companies are more likely to use reusable bottles. A company said they have started the United States' first state-wide reusable beer system. More obviously, Szaky's idea of reusable packaging for products has attracted more and more companies to pay attention to the reusable packaging. 5. What do we know about Tom Szaky from paragraph 1 A. He invented Coke bottles. B. He recommended using reusable containers. C. He invented a new kind of container. D. He asked people for deposit. 6. Why does Szaky keep the ice cream in a special box A. To help keep its temperature. B. To make it easy to eat. C. To make it sweeter. D. To help it melt quickly. 7. What can we infer about the reusable packaging in the future A. It will solve plastic waste completely. B. It will bring about a lot of new waste. C. It will attract more and more attention. D. It will make Loop lose a lot of customers. 8. What is the best title for the text A. Different New Ways to Deal with Plastic Pollution B. The Story of a Creative Inventor C. The World's Attitude to Plastic Pollution D. An Old Idea of Fighting against Plastic Pollution 答案: A 【解题导语】这是一篇议论文。文章谈的是古建筑人行道的保护和历史,并呼吁其应该得到保护。 1. B. 细节理解题。根据第一段最后一句Yet they often go unprotected even when they may be older than neighbouring historic buildings that have enjoyed protection for tens of years. (然而,尽管它们比周围那些享受了十来年保护的历史建筑还要古老,但是它们却没有得到保护。)可知历史人行道尽管比一些得到保护的建筑古老得多,但它们还是没有得到应得的保护。故选B。 2. D. 细节理解题。根据第三段中的Before the laying of pavement, streets of dirt caused many problems to citizens, especially in wet weather when they became muddy(泥泞的),which limited the movement of people and vehicles.(在铺人行道之前,泥泞的街道给市民造成了很多问题,尤其是在潮湿的天气它们变得泥泞的时候,这限制了人和车辆的行动。)可知本段论述了没有人行道的状况,道路泥泞阻碍出行,反过来可知修建人行道就是为了解决通行问题,便利生活,故选D。 3.D. 主旨大意题。根据文章第四段To solve the problem,cities experimented with a wide range of materials in an attempt to balance durability(耐用性),economics,sources of materials and noise considerations.(为了解决这个问题,各城市实验了各种各样的材料,试图在耐用性,经济,材料来源和噪音之间找到平衡),再根据第五段和第六段,分别讲述了天然鹅卵石、裸石及砖块各自的优缺点,可知,这三段主要讲人行道上的不同材料的发展。故选D。 4. C. 推理判断题。根据最后一段第二句However, they are more similar to the early high buildings and parks -important city features that showed the modernization of the city. (然而,它们更类似于那些展示城市现代化发展的重要城市标志---大楼和公园)可知作者认为古建筑人行道的作用,就等同于现代城市中的那些标志性建筑,这些人行道也是一个特定的地方所独有的。故选C。 B 5. B. 细节理解题。根据第一段中Tom Szaky's way may be one of the bravest. He has gone back to an old way-using reusable containers.( Tom Szaky的方式可能是最勇敢的。他又回到了老方法---使用可重复使用的容器)可知,Tom Szaky建议使用可重复使用的容器。故选B。 6. A. 细节理解题。根据第二段中One of his products is Haagen-Dazs ice cream that is packed inside a special box to keep the ice cream from melting.(他的其中一个产品是哈根达斯冰淇淋,它被包装在一个特殊的盒子里,以防止冰淇淋融化)可知,Szaky把冰淇淋放在一个特殊的盒子里,是为了帮助冰淇淋保持温度,不融化。故选A。 7. C. 推理判断题。根据最后一段中More obviously, Szaky's idea of reusable packaging for products has attracted more and more companies to pay attention to the reusable packaging.(更明显的是,Szaky的产品可重复使用包装理念已经引起了越来越多的企业对可重复使用包装的重视)可推知,可重复使用的包装会吸引越来越多的人注意。故选C。 8. D. 标题确定题。根据第一段中There are many ways to deal with the plastic pollution. Tom Szaky's way may be one of the bravest. He has gone back to an old way-using reusable containers.(有很多方法来处理塑料污染。Tom Szaky的方式可能是最勇敢的。他又回到了老方法---使用可重复使用的容器)结合文章主要介绍了Tom Szaky通过使用可重复使用的容器来处理塑料污染,说明了可重复使用的容器想法的起源和发展,以及Szaky是如何利用可重复使用容器的。可知,D选项An Old Idea of Fighting against Plastic Pollution"一个与塑料污染作斗争的旧观念"最符合文章标题。故选D。 这是一篇说明文。文章主要介绍了Tom Szaky通过使用可重复使用的容器来处理塑料污染,说明了可重复使用的容器想法的起源和发展,以及Szaky是如何利用可重复使用容器的。 预习思考 预习第二单元Reading部分的核心词汇和句型。课程主题:M3U1下核心知识点梳理 授课时间:

There are many reasons to protect historic pavements - culture value, economics, environmental benefits and public safety. Pavements represented an important step in the modernization of city environments in the 19th century. Before the laying of pavement, streets of dirt caused many problems to citizens, especially in wet weather when they became muddy(泥泞的), which limited the movement of people and vehicles. To solve the problem, cities experimented with a wide range of materials in an attempt to balance durability(耐用性), economics, sources of materials and noise considerations. The earliest pavement in many cities were cobblestones-naturally rounded stones. They were cheap and durable,but rough and noisy. Loose stone pavements were cheap and smooth, but not very durable. Wood also appeared in the 1850s as a popular option-smooth, quiet and affordable,but not very durable. In many cities and towns, brick(砖)streets are the only historic pavements that have survived. This fact covers up the truth of pavement experimentation between the 1850s and 1920s, when a city could use up to a dozen different paving materials at the same time! Indeed, each city developed a unique "pavement identity" in the materials chosen and the way they were laid. It is easy to think of the past when seeing historic pavements, as recalling "old world" city qualities. However, they are more similar to the early high buildings and parks-important city features that showed the modernization of the city. At a time when cities are becoming increasingly similar, such pavements also help define an important sense of place. 1. What is the present situation of historic pavements A. Failing to represent modem environments. B. Failing to receive protection they should get. C. Being brought back to its former glory. D. Being highly valued as cultural buildings. 2. Why was the first pavement built in history A. To help develop the local economy. B. To prevent earth from being washed away. C. To limit the movement of people and vehicles. D. To bring convenience to citizens' life. 3. What is mainly talked about in Paragraphs 4-6 A. Popularity of different paving materials. B. Different experiments on city identity. C. Advantages and disadvantages of stone pavements. D. Development of pavements of different materials. 4. What does the writer want to express about historic pavements in the last paragraph A. They are similar to tall buildings. B. They make cities appear similar. C. They are unique of a particular place. D. They represent the modernization of today's city. B There are many ways to deal with the plastic pollution. Tom Szaky's way may be one of the bravest. He has gone back to an old way-using reusable containers. The idea was used in the last century. It was introduced to the world by Coca-Cola in the early 1920s, when Coke was sold in expensive glass bottles that needed returning. They asked for two cents, about 40 percent of the full cost of the soft drink, and got about 98 percent of their bottles back, to be reused 40 or 50 times. Bottle deposit programs remain one of the most effective methods. Ten months ago, Szaky started Loop, an online delivery service that uses strong reusable containers. The biggest part of his risk is that Loop pushes far beyond the common reusable bottles. From food packaging to washing powder packaging,the containers are in different sizes and made from different materials. One of his products is Haagen-Dazs ice cream that is packed inside a special box to keep the ice cream from melting. 17 years ago, Szaky founded TerraCycle, a small waste management company. He thought up a way to deal with plastics, cigarette wastes, and a long list of other wastes. Gradually, he became more interested in thinking of how to recycle different kinds of waste in the best way. Loop is part of the reappearance of the reusable packaging as a best choice to plastic waste. The food and drink companies are more likely to use reusable bottles. A company said they have started the United States' first state-wide reusable beer system. More obviously, Szaky's idea of reusable packaging for products has attracted more and more companies to pay attention to the reusable packaging. 5. What do we know about Tom Szaky from paragraph 1 A. He invented Coke bottles. B. He recommended using reusable containers. C. He invented a new kind of container. D. He asked people for deposit. 6. Why does Szaky keep the ice cream in a special box A. To help keep its temperature. B. To make it easy to eat. C. To make it sweeter. D. To help it melt quickly. 7. What can we infer about the reusable packaging in the future A. It will solve plastic waste completely. B. It will bring about a lot of new waste. C. It will attract more and more attention. D. It will make Loop lose a lot of customers. 8. What is the best title for the text A. Different New Ways to Deal with Plastic Pollution B. The Story of a Creative Inventor C. The World's Attitude to Plastic Pollution D. An Old Idea of Fighting against Plastic Pollution 预习思考 预习第二单元Reading部分的核心词汇和句型。
