篇1：初三英语（人教版）Unit 2重难点解析
1. [原文]Have you ever watched someone surf? （L. 6）surf是动词，在这里怎么用原形？
[精析] surf是省去to 的动词不定式，在这里作感官动词watch的宾语补足语。类似用法还有，感官动词look at, see, listen to, hear, 使役动词let, have，make等，后都可以接省去to的不定式作宾补。
2. [原文] Now it is enjoyed by people all over the world. (L. 6) is enjoyed是什么谓语形式？all over是什么用法？
[精析]is enjoyed是被动语态形式。当主语为动作的承受者时，谓语要用被动语态形式，即be + 过去分词形式。这部分内容在今后还要学到。
all over是“全部、浑身、在各地”的意思，可单独使用，也可在其后接相应的词语。例如：
People all over the world love peace.全世界的人民都热爱和平。
He is wet all over.他全身都湿了。
all over the world 也可以用all the world, the whole world 来表示，但一定要注意冠词的位置。用all 时，冠词放在all之后，用whole时，冠词放在whole之前。
3. [原文] Every year...attract large numbers of tourists to the islands. (L. 6) large numbers of与a large number of 有区别吗？
[精析]没有。这两个短语都表示“许多”的意思，可以互换。如：Large numbers of / A large number of people came to the meeting from all over the country. 许多来自全国各地的人参加了会议。但是a number of / numbers of 与the number of是有区别的。作主语时，前者后接复数名词，谓语用复数形式；后者意思是“为……的总数”，后接复数名词，但谓语要用单数。试比较：
A number of students are playing in the playground.许多学生在操场上玩。
The number of students in the playground is about one hundred.操场上的学生（数量）大约有一百人。
4. [原文] For example, Jake Booth, a 21-year-old man, gave up his job in San Francisco a year ago. (L. 6) 21-year-old中的year怎么不加s？
[精析] 21-year-old是由数词 + 名词 + 形容词构成的复合形容词，其中year不可以用复数形式，词与词之间用连字号。试比较：
He is a 15-year-old boy.他是一个15岁的男孩。
The boy is 15 years old.这个男孩15岁。
另外，句中give up意思是“放弃”，作及物动词，后可以接动名词；也可以接代词，用宾格放于up之前。也可用作不及物动词。例如：
You should give up smoking. I gave it up last year.你应该戒烟。我去年就戒掉了。
She doesn't give up easily.她做任何事情都不会轻易放弃。
5. [原文] Although I haven't got a very good job, surfing keeps me very fit.( L. 6) although与though用法相同吗？
[精析] 有共同之处，也有不同点。两都可用来引导让步状语从句，表示汉语的“虽然……但是……”。但不能说although / though...but...。如：不能说：Although / Though he is very old, but he is still quite strong. 句中的but 应去掉。Although是较为正式的用语，引导的从句多位于主句前，though多用于非正式文体中，引导的从句位于主句前后都可。
注意：though可用于倒装句中，although不可。如：Young though he is , he has worked for a few years.他虽然年轻但已经工作好几年了。
6.[原文] He's gone to New Zealand on business. (L. 7) business前可以加定冠词the 吗？
[精析] 不可以。on表示“处于……状态中”，与一些名词构成特定的词组，on business出差。再如：on duty值日，on fire着火了，on holiday在度假。这些固定词组中都不能加冠词。
7. [原文] On May 17, , on his 13th birthday, his dream came true.(L. 8) come true是“实现”的意思，realize也有这一意思，它们的用法一样吗？
[精析] 不一样。这两个词语虽然可以表示同一个意思，但句法结构不同。come true的主语应是某事，而realize的主语应是某人。试比较：
His dream has come true.他的梦想实现了。
He has realized his dream.他实现了他的梦想。
另外，表示某人几岁生日是：one's + 序数词 + birthday。如：Tom's 10th birthday.
8. [原文] He went on cycling for another two hours before he finished his journey. (L. 8) 句中的journey与trip, travel均可表示“旅行”，有区别吗？
[精析] 有区别。这三个词都表示“旅行”的意思。journey 一般指较远距离的旅行，指单程；trip用得比较广泛，可以是“旅行”，也可以是“去了一下”，但都指一个往返；travel一般指到国外或远方旅行，不着重某一个目的地，有到各地“游历”的意思。请看例句：
He made a journey from Paris to Berlin.他作了一次从巴黎到柏林的旅行。
I took several trips to Guilin.我去过桂林几次。
He returned from his travels.他旅行结束回到家里。
篇2：人教版初三Unit 18 重难点解析
作者：刘世一
1. [原文] I'm beginning to get angry with him. (L.69)句中begin是终止性动词，却用了进行时态，怎么理解这一语法现象？
[精析] 在英语中，终止性动词由于动作不能延续的特性，一般情况下没有进行时态，也不与时间段状语连用。而英语中某些终止性动词如come, go, leave, begin, start, return, move等的进行时态形式，可用来表达将来的含义，本句就是这一用法。如：
They are leaving for Beijing on business.他们要出差去北京。
The Greens are moving into a new flat.格林家准备搬进新公寓。
2. [原文] However, it is still not known whether he and Irvine ... (L.70)本句是什么句子结构？
[精析] 这是一个主从复合句，whether引导的是主语从句，句首的it是形式主语。在英语中，往往采用“it is +过去分词+从句”这一结构。如“据说，据报道，据以为”等含义。如：
It is said that he is a good doctor.据说他是个好医生。
It is reported that China has sent another man-made earth satellite into orbit. 据报道，我国又发射了一颗人造地球卫星进入轨道。
3. [原文] ..., but some people wondered whether .... (L.70)动词wonder有哪些用法？
[精析] wonder这一动词在不同的句子结构中表达的意思不同：
(1) 后接“who, what, why等疑问词引导的宾语从句”、“疑问词+不定式”时，表示“想知道”。如：
The teacher wondered why she was late. 老师想知道她为什么迟到。
He wondered what happened. 他想知道发生了什么事情。
I'm just wondering how to do it. 我正想知道怎么做那件事。
（2）后接“that引导的宾语从句”、“不定式短语”时，表示“感到惊奇；对......感到惊讶”。如：
I wonder that he was off office.我对他下岗感到惊讶。
I wonder to see her looking so cheerful. 我很惊讶地发现她如此高兴。
（3）后接if或whether引导的宾语从句时，表示一种委婉的请求或疑问。如：
I wonder if you would mind giving me a hand. 我想知道你是否介意助我一臂之力。
（4）后接at 或about表示“感到惊异；感到疑惑”的意思。如：
I wonder at your allowing her to do such a thing. 我对你允许她做那样的事感到惊异。
I wonder about my future.我对我的未来感到疑惑。
4. [原文] ... live in less developed countries are quite poor. (L.71)句中developed可改为developing吗？
[精析] developed和developing是动词develop的过去分词和现在分词形式，在句中作定语，两者的区别是：（1）在时间上，现在分词表示动作正在进行，过去分词表示动作已经完成。（2）在语态上（这条规则只符合及物动词）, 现在分词表示主动，过去分词表示被动。所以developed countries是“已经发展了的国家，即发达国家”，改为developing countries是“正在发展的国家，即发展中国家”，这样句意就发生了改变。再如：
We knew the surprising fact.我们知道了那个使人感到惊讶的事实。
Those surprised people didn't move at all.那些受了惊的人们呆在那儿一动不动。
篇3：人教版初三Unit 17重难点解析
作者：吕新军
1．[原文] ① But I heard him speak.(L.65) ② Suddenly, they hear someone outside shouting: ...(L.66)为什么①句中speak用原形，而②句中shouting用的是V-ing形式？
[精析] 感官动词hear后可以接动词原形和V-ing作宾语补足语，即hear sb. do或hear sb. doing。二者的区别是：前者表示后边的动作已经完成，后者表示后边的动作正在进行。试比较：
I heard him say that the matter was yet undecided. 我听见他说那件事还没决定。
I heard somebody laughing. 我听见有人在笑。
2．[原文] I'll shoot anyone who moves!
(L.66)动词shoot后如果加一个介词at，意思有变化吗？
[精析] 有。 shoot作及物动词，表示“击中”，后接被击中的对象。如：
He shot the bird dead. 他把那只鸟射死了。
当表示“向......射击”时，要用短语shoot at，此时不强调结果。如：
He shot at a dog, but missed it. 他朝狗开枪，但没打中。
3．[原文] Who would you ask for help if you were robbed? (L.66)这句话在本课中并不表示过去，而谓语动词却用的是would ask和were，这是什么语法现象？
[精析] 这是一个含虚拟语气的句子。在英语中，表达的假设或不大可能发生的事时，要使用虚拟语气。如果假设与现在事实相反或与将来事实可能相反，条件从句为“if +主语+动词过去式”, 主句为“主语+should (would)+动词原形”。（这种语法现象在以后会学习到。）如：
If I were you, I would leave him at once. 如果我是你，就立刻离开他。
句中ask sb. for help是“向某人求助”。ask sb. for sth. 是“向某人要求某物”，ask for sb. / sth. 表示“要求见某人；要求与某人谈话；要某事物”等等。如：
She asked him for advice. 她向他征询高见。
Did anyone ask for me? 有人找我吗？
Did you ask your boss for a pay increase? 你请求老板加薪了吗？
篇4：Unit 10重难点解析 (人教版高一英语下册教学论文)
Unit 10重难点解析
1. Use the questions below to get started and try to think of more questions.(Speaking)
get started意为 “开始活动、工作等”。类似的还有：get washed洗脸；get dressed穿衣；get lost迷路。如：
Sarah, hurry up. I’m afraid you wouldn’t have time to _____ before the party. (NMET I)
A. get changed B. get change
C. get changing D. get to change
此题选A。句意为 “你恐怕在晚会开始之前没有时间换衣服了”。
2. We often talk about how important it is to take good care of ourselves and our planet... (Reading)
这里宾语从句是一个感叹句结构，how是感叹副词。如：
You can’t imagine how proud Du Li was when she won the first gold medal in the 2004 Athens Olympic Games.
你难以想象当杜丽赢得雅典奥运会首枚金牌时是多么自豪。
Parents are taught to understand ______ important education is to their children’s future. (广东2004)
A. that B. how C. such D. so
此题选B。宾语从句是一个感叹句结构，原句缺少感叹副词how。
3. When the habitat of a species is changed or destroyed, the animal or plant has to either adapt to the change or find a new home. (Reading)
1）species意为“（动植物）物种；种类”，单复数同形。如：
A species can become endangered for different reasons.
一个物种濒危可能是各种原因引起的。
The Origin of Species was written by Charles Darwin.
《物种起源》是查理达尔文写的。
2）either...or...是并列连词，连接两个并列成分，意为“或者……或者……”。连接并列主语时，谓语要与邻近的主语保持人称和数的一致。如：
Either my father or my brothers are coming. 不是我父亲就是我兄弟要来。
Either say you’re sorry or else get out! 你要么道歉,要么滚开!
3）adapt意为“使适应(to)；使适合(to)；改编(for; from)”。如：
You should adapt yourself to the new environment. 你应该适应新环境。
The movie was adapted from a novel.
这部电影是由小说改编的。
4. Even small things can make a big difference. (Post-reading)
1）even用作副词，意为“甚至；更”，起加强语气的作用。如：
Everyone was on time for the meeting -_____ Chris, who’s usually ten minutes late for everything. (湖南2004)
A. but B. only C. even D. yet
此题选C。这里even表示强调，意为“即使；连……都”。
2）make a/no/much difference意为“有影响/无关紧要/很重要”。如：
Exercise can make a big difference to your state of health.
锻炼对你的身体状况影响很大。
5. Professor Stevenson, who has devoted himself to protecting the milu deer, gave a talk to Chinese college students in Beijing. (Grammar)
devote oneself/one’s life/one’s time to表示“把自己/某人一生/某人的时间投身于”，to 是介词，后接名词、代词或动词-ing形式。devoted to表示“专心致志于, 献身于；热爱，很喜欢”。如：
Although the working mother is very busy, she still ______ a lot of time to her children. (上海)
A. devotes B. spends C. offers D. provides
Reed made up his mind to devote all he had to _____ some schools for poor children. (上海春)
A. set up B. setting up C. have set up D. having set up
Her son, to whom she was so _______, went abroad ten years ago. (上海2001)
A. loved B. cared C. devoted D. affected
这三个题的最佳选项分别为A、B、C。例1和例3侧重于动词词义辨析和该短语的识别；例2侧重于该结构中介词to的判断与运用。he had是定语从句，修饰先行词all, 此处省略了关系代词that。
6. Reduce the amount of rubbish. [Integrating Skills]
reduce常用作及物动词，意为“减少，缩小（尺寸、数量等），降低（价格、程度等）”。如：
-The cars give off a great deal of waste gas in the streets.
-Yes. But I’m sure something will be done to _____ air pollution. （上海）
A. reduce B. remove C. collect D. warn
此题选A。从上句“汽车排出大量的废气”可知，应用reduce表示“采取措施的目的”是“降低空气污染的程度”。

篇5：Unit 9 重难点解析 (人教版高一英语下册教学论文)
Unit 9 重难点解析
1. Modern cellphones are more than just phones - they are being used as cameras and radios, and to send e-mail or surf the Internet.(Reading)
more than本意为“多于,超过”,可引申为“不仅仅;远不止;极其”。如:
They were more than willing to help.
他们非常愿意帮忙。
She was more than frightened at the sight.
看到这情景,她简直吓坏了。
动词不定式短语to send e-mail...是跟在they are being used后面的。也就是说,这个句子应该是:They are being used to send e-mail or surf the Internet.
2. The latest cellphones have features such as games, music and an electronic calendar that will remind you about appointments and important dates.(Reading)
remind 作 “使……想起”解时,后可接of引起的短语或从句。如:
The story you have just told reminds me of an experience I once had.
你刚才讲的那个故事使我想起了我的一次经历。
That reminds me that I must write to him.
那使我想起来我该给他写信了。
remind 作 “提醒”解时, 后可接带不定式的复合结构, 也可接of或about引起的短语, 还可接从句。如:
Remind him to close the windows when he leaves.
提醒他在离开时把窗子一一关上。
She asked me over the telephone to remind you about the party.
她打电话来要我提醒你不要忘了赴宴。
3. They are being used everywhere - sometimes where they shouldn’t.
(Reading)
句中are being used为现在进行时的被动语态;where引导的是一个地点状语从句,表示“在……的地方”;shouldn’t 的后面省略了be used, 以避免重复。如:
Put things where you can easily find them.
把东西放在你容易找到的地方。
These words were said where they shouldn’t.
这些话说在了不该说的地方。

篇6：初三Unit 8 重难点解析
作者：严建英
1. Q: To be here at Christmas time is a dream that has come true. 请分析一下本句的结构。
A：本句是一个主从复合句。句中To be here at Christmas time是动词不定式作主语，is a dream是系表结构，that 引导的是定语从句，修饰dream。关于定语从句会在17单元学到。
2. Q: Some people even put up stocking for their pets as well. 句中as well表示“也”与其它几种表达方式有什么异同？
A: 汉语的“也”英语可用too, also, as well和either表示，其区别是：too是普通用词，常置于句子末尾且用逗号与句子隔开；also是比较正式的用语，它一般位于be动词、情态动词、助动词等之后，行为动词之前；as well用法与too相同，通常位于句尾，但前面一般不用逗号； either表示“也”时，一般只用于否定句中，且置于句子末尾，用逗号与句子隔开。试比较：
I would like to go fishing on Sunday, too.
He has also been to the top of Mount Tai.
He is a teacher, and a writer as well.=He is a teacher, and he is a writer, too.
The students didn't work out the problem. The teacher didn't, either.
3. Q: Even though Father Christmas is no longer living, ... even though引导什么从句？
A: even though作为连词，意为“虽然......；尽管......”，引导让步状语从句。如：
Even though he is poor, she still loves him.
4. Q: It is said that ... she was to have this special boy. 句中was to have是什么结构？
A: “be to + 动词不定式”这种结构常用来表示按计划安排将要发生的事情，是将来时态的另一表达形式。如：
They are to arrive in Beijing at 4 o'clock this afternoon.
The new shop is not to be opened untill next week.
篇7：初三Unit 2 重难点解析
作者：严建英
1. [原文]Have you ever watched someone surf? （L. 6）surf是动词，在这里怎么用原形？
[精析] surf是省去to 的动词不定式，在这里作感官动词watch的宾语补足语。类似用法还有，感官动词look at, see, listen to, hear, 使役动词let, have，make等，后都可以接省去to的不定式作宾补。
2. [原文] Now it is enjoyed by people all over the world. (L. 6) is enjoyed是什么谓语形式？all over是什么用法？
[精析]is enjoyed是被动语态形式。当主语为动作的承受者时，谓语要用被动语态形式，即be + 过去分词形式。这部分内容在今后还要学到。
all over是“全部、浑身、在各地”的意思，可单独使用，也可在其后接相应的词语。例如：
People all over the world love peace.全世界的人民都热爱和平。
He is wet all over.他全身都湿了。
all over the world 也可以用all the world, the whole world 来表示，但一定要注意冠词的位置。用all 时，冠词放在all之后，用whole时，冠词放在whole之前。
3. [原文] Every year...attract large numbers of tourists to the islands. (L. 6) large numbers of与a large number of 有区别吗？
[精析]没有。这两个短语都表示“许多”的意思，可以互换。如：Large numbers of / A large number of people came to the meeting from all over the country. 许多来自全国各地的人参加了会议。但是a number of / numbers of 与the number of是有区别的。作主语时，前者后接复数名词，谓语用复数形式；后者意思是“为……的总数”，后接复数名词，但谓语要用单数。试比较：
A number of students are playing in the playground.许多学生在操场上玩。
The number of students in the playground is about one hundred.操场上的学生（数量）大约有一百人。
4. [原文] For example, Jake Booth, a 21-year-old man, gave up his job in San Francisco a year ago. (L. 6) 21-year-old中的year怎么不加s？
[精析] 21-year-old是由数词 + 名词 + 形容词构成的复合形容词，其中year不可以用复数形式，词与词之间用连字号。试比较：
He is a 15-year-old boy.他是一个15岁的男孩。
The boy is 15 years old.这个男孩15岁。
另外，句中give up意思是“放弃”，作及物动词，后可以接动名词；也可以接代词，用宾格放于up之前。也可用作不及物动词。例如：
You should give up smoking. I gave it up last year.你应该戒烟。我去年就戒掉了。
She doesn't give up easily.她做任何事情都不会轻易放弃。
5. [原文] Although I haven't got a very good job, surfing keeps me very fit.( L. 6) although与though用法相同吗？
[精析] 有共同之处，也有不同点。两都可用来引导让步状语从句，表示汉语的“虽然……但是……”。但不能说although /
