(P34) 有人想在不到五天的时间内穿越加拿大。【句法分析】此处that you can cross Canada in less than five days是同位语从句， 是idea的同位语，用来说明idea的具体内容。【教材原句】People say it is Canadas most beautiful city, surrounded by mountains and the Pacific Ocean. (p34) 人

17、们说这是加拿大最美丽的城市，被大山和太平洋环绕。【句法分析】1、此处surrounded by mountains and the Pacific Ocean 是过去分词作原因状语， 相当于状语从句because it is surrounded by mountains and the Pacific Ocean.过去分词作状语，表原因、条件，伴随等。一般置于句首，也可置于句末。Eg： He soon fell asleep, exhausted by the journey.Seen from the hill, the city looks magnificent.Given good

18、health, I hope to finish the work this year.They came in, followed by 3 children.2、 surrounding, adj. 周围的，附近的 eg: surrounding country 【教材原句】 Because of the Great Lakes, they learned, Canada has more fresh water than any other country in the world.他们知道，因为五大湖，加拿大的淡水比世界上任何国家都多。【句法分析】该句运用了形容词比较级表示最高级。英语

19、中用比较级句型可以表最高级的含义，较为常见的有下列几种形式：1、直接使用比较级How beautiful she sings! I've never heard a better voice.  = She has the best voice I've ever heard. I have never read a more

20、60;interesting novel. = It is the most interesting novel I've ever read.   any other + n.(单)2、 比较级+ than +  the other +n.(复) any of the other + n.（复）She goe

26、160;is my sisters best friend. 【教材原句】 In the distance, they could see the misty cloud that rose from the great Niagara Falls, which is on the south side of the lake.远处，他们可以看到湖的南边尼亚加拉大瀑布上方升腾着的雾霭。【句法分析】1、 in the distance 在远处；相当于 far away， 强调距离远。2、 that 引导的是一个定语从句，修饰the misty c

27、loud，表示“升起的misty cloud“。3、 rose是rise的过去式。表示上升。辨析rise、arise、raise、arouse 首先， rise, arise 是不及物动词raise, arouse是及物动词 1. rise（rose, risen）vi. 上升，升起, 升高；上涨；文：（躺 坐或跪后）起立，起身；起床说明主语自身移向较高位置，常用于日、月、云、雾、烟、蒸汽、河水、温度、物价等，无被动语态。 1) The sun rose at seven oclock. 太阳七点钟升起。2) The moon has risen above the hills. 月亮已经从山

28、上升起。 3) The river has risen by several meters.河水上涨了好几米。4) The river is rising after the rain. 雨后河水涨了。5) The temperature in the room is rising higher and higher. 房间里的温度越升越高。6) Soon steam can be seen rising from the wet clothes. 很快就看见水蒸气从湿衣服里冒出来。7) The price is rising. 物价正在上涨。2、 arise (arose, ari

29、sen) vi. .(问题，困难等)出现；发生， 产生；主语一般为抽象名词，如problem, trouble, quarrel, difficulty, misunderstanding, disagreement古：起身；起来；起立。无被动语态。常用短语：arise from / out of sth.由引起；因产生。 如：1) Problems arose from the outset.一开始就产生了很多问题。2) How did the quarrel arise? 争吵是怎么引起的？3) They are talking about problems arising out of

30、the lack of communication.他们正在谈论由于缺乏交流而产生的问题。3、 raise vt. 说明主语发出的动作是要作用于其它事物的，往往有使物体达到其应有的高度的含义。可用于被动语态。如： 1) 招募：to raise an army 2) 养育、栽培：to raise a family 3) 提高raise salaries工资, raise the rent租金。4) 举起raise ones hand 5) 提出问题 raise a question 1) Salaries have now been raised. 现在薪水已增加了。 2)

31、The price was raised to 10. 价格涨到十英镑。 3) Heavy rain raised the river stage. 暴雨使河水水位升高。4) The boss promised to raise her salary. 老板答应要给她加薪水。4、 arouse意为“激起，唤醒；使. 奋发” 可用于被动语态1) arouse ones interest / sympathy“唤起某人的兴趣 / 同情心” 2) arouse sb. 唤醒某人3) He fell into a sound sleep, don't arouse him.

32、 他睡熟了，别唤醒他。4) He was aroused from his sleep by the doorbell. 门铃声把他从睡眠中唤醒。总结： arise 没有“上升”之意，多指“产生、发生和出现”，常用于抽象事物 rise 使用范围广，既用于具体事物的“上升、增长”，又用于抽象事物的“上涨” raise 与以上两词不同的是，此词是及物动词，表示把某具体事物抬起高处或提高某抽象事物【教材原句】 It is too bad the Chinese cant go as far as Ottawa, Canadas capital.很可惜你们不能一直走到加拿大的首都渥

33、太华。【句法分析】1、该句结构是It+ 系动词+形容词+that从句。如：It is necessary/ clear/ likely/ important that 有必要/很清楚/很可能/重要的是类似的形容词还有：strange; natural; obvious; true; good; wonderful; possible; unlikely; quite; unusual; certain; evident; worth-while; surprising; interesting; astonishing, etc. Eg: It is no surprise that Bob

34、should have won the game. It is a pity that you missed the film. 2、go as far as 一直走到 eg. This is as far as we go. as/so far as sb. knows 就某人所知 as far as sb. can see/tell/ remember 就某人看来/所说/所记得as/so far as sb / sth is concerned 就某人/事物而言far from sth 毫不；一点也不； 远非So far, so good. (谚) 到目前为止，一切都很顺利。考点/易错点3

35、 语法点学习 表语从句和同位语从句表语从句1 定义：用作表语的从句叫做表语从句。2 引导表语从句的关联词的种类：(1) 从属连词that。在从句中不做成分。如：The trouble is that I have lost his address.  麻烦是我把他的地址丢了。 The reason was that he was late for school.(2) 从属连词whether, as, as if。如：1. He looked just as he had looked ten years before.  他看起来还与十年前一样。2.

36、The question is whether they will be able to help us. 问题是他们是否能帮我们。注：从属连词if一般不用来引导表语从句，但as if却可引导表语从句，如：All this was over twenty years ago, but its as if it was only yesterday.这都是20多年前的事了，但宛如昨天一样。The key is whether we can solve the problem. 看起来好像要下雨。It looked as if it was going to rain.注：能跟表语从句的谓语动词一

37、般为系动词be, seem, look，sound等。如：He looked just as he had looked ten years before. 他看起来还与十年前一样。 造句：听起来好像有人在敲门。It sounds as if someone is knocking at the door. (3) 连接代词who, whom, whose, what, which, whoever, whatever, whichever 在表语从句中做主语、宾语等。如：The problem is who we can get to replace her. 问题是我们能找到谁去替换她呢。

38、That was what she did this morning on reaching the attic. 那就是她今晨上了阁楼干的。 造句： 问题是我们能找到谁去替换她呢。 The problem is who we can get to replace her.我想问的是谁离开了。 My question is who left. (4) 连接副词 where, when, how, why。What I wonder is when he left. 我想知道他是何时离开的。This is where they once lived. 这就是他们曾经住过的地方。造句：这就是他为何

39、没到这儿来的原因。 That is why he didn't come here. 造句：问题是他是如何做此事的。 The question is how he did it.  (5) 连词because可引导表语从句。如：I think it is because you are doing too much. 我想这是因为你做得太多。造句：这是仅仅因为他不认识她。 It's just because he doesn't know her. That's because he didn't understand me. 那是因

40、为他没有理解我。(That's because.强调原因) That's why he got angry with me. 那正是他对我生气的原因。 (That's why.强调结果) (6) 在一些表示“建议、劝说、命令”的名词后面的表语从句中，谓语动词用虚拟语气。should+动词原形表示，should可省略。如：My suggestion is that we (should) start early tomorrow. 我的建议是我们明天一早就出发。同位语从句同位语从句说明其前面的名词的具体内容。1、 同位语从句通常由that引导，可用于同位语从句的名词有ad

41、vice、demand、doubt、fact、hope、idea、information、message、news、order、problem、promise、question、request、suggestion、truth、wish、word、rumor等抽象名词。例如：The news that we won the game is exciting. 我们赢得这场比赛的消息令人激动。I have no idea when he will come back home. 我不知道他什么时候回来。The thought came to him that Mary had probably

42、fallen ill. 他想到可能玛丽生病了。2、如同位语从句意义不完整，需增加"是否"的含义，应用whether引导同位语从句。例：We'll discuss the problem whether the sports meeting will be held on time.析：the sports meeting will be held on time意义不完整，应加"是否"的含义才能表达the problem的全部内容，因此应用whether引导同位语从句。3、如同位语从句意义不完整，需增加"什么时候"、"

43、;什么地点"、"什么方式"等含义，应用when, where, how等词引导同位语从句。Eg: 1：I have no idea when he will be back. 2：I have no impression how he went home, perhaps by bike. 4、当主句的谓语较短，而同位语从句较长时，同位语从句常后置。eg：The thought came to him that maybe the enemy had fled the city. 同位语从句与定语从句的区别：1、 定语从句中的that既代替先行词，同时以在从句中作

44、某个成分（主语或宾语），而同位语从句中的 that是连词，只起连接主句与从句的作用，不充当句中任何成分。2、 定语从句是形容词性的，其功能是修饰先行词，对先行词加以限定，描述定的性质或特征；同位 语从句是名词性的，其功能是对名词进行补充说明。例如：1) The news that he told me is that Tom would go abroad next year.（他告诉我的消息是汤姆明年将出国。）2)The news that Tom would go abroad is told by him.（汤姆将出国的消息是他讲的。）I had no idea that you wer

45、e here（that引导同位语从句，不能省略）Have you got the idea（that）this book gives you of life in ancient Greece？（that引导定语从句，作宾语，可以省略）四、例题精析【例题1】 【题干】To some people，happiness _family and friends. 对于有些人来说，幸福就是被朋友和家人包围着。 【答案】is being surrounded by 【解析】本题考查词汇surround的使用。【例题2】 【题干】The National Stadium which looks very

46、magnificent_258,000 square metres in area.Ais measuring Bis measuredCmeasured Dmeasures【答案】：D【解析】：句意：看起来非常辉煌的国家体育馆面积为258 000平方米。measure在此处为不及物动词，指尺寸、长短、数量等。用作此含义时，不能用于进行时，也不能用于被动语态。【例题3】 【题干】These soldiers defend the _ area of China's North all year round.Aborder BharborCglobe Dscenery【答案】：A【解析】

47、：句意：这些士兵整年都在保卫中国北疆国门。border国界，国门；harbor港口；globe地球；scenery景色。 五、课堂运用【基础】1、More consumers are waiting for the further drop of housing prices with money in their hands rather than _ houses，according to a report.Ato buy BbuyingCbuy Dbought【答案】B【解析】rather than连接平行结构，由句子中的waiting for.可知rather than后应用buying。 2、The girl who is studying at the art college has a _ for music and dance.Agift BpresentCpower Dstrength 【答案】A 【解析】词组have a gift for的含义是“在有天赋”。present作“礼物”讲与gift是同义词，但它没有
