二、核心句型

三、重点语法

【考点精讲】
一、核心词汇
1．fantastic adj.
[考点点拨]意为“极好的，美妙的”。a fantastic beach一片极好的海滩；a fantastic achievement 一项了不起的成就；have a fantastic time＝have a good/great/wonderful time玩得开心。fantasy n．(pl. fantasies)幻想，想象。如：
Stop living in a fantasy world别再生活在幻想世界中了。
2．such det.& pron.
[考点点拨] such意为“这样的（人或物）”，常用于以下结构：
such+a/an+adj.+可数名词单数。如：
This is such a big house.这是一座如此大的房子。
such+adj.+可数名词复数。如：
They are such kind girls.她们是如此好心的女孩。
such+adj.+不可数名词。如：
It is such sad music.它是如此悲伤的音乐。
[辨析] so常用于以下结构：
so+adj.+a/an+可数名词单数。如：
so clever a boy如此聪明的一个男孩
so+adj.／adv.。如：
so clever如此聪明；so quickly如此迅速
so many/much/few/little+n．。如：

3．couple n．

二、核心句型
1.I don't think it'll be a holiday for me.
我想这对我来说不会是个假期了。
[考点点拨]本句原为“I think it won't be a holiday for me.”这是一个“否定前移”的句子，主句中的否定词实际上否定的是后面从句的内容。在英语中，当主句是I think，I believe等时，其后的宾语如果是否定式，则要把否定前移至主句，表达成“I don't think/believe+肯定句”的句式。这是因为英美人士在表达个人观点时比较委婉。如：
I don't think he is an honest boy.
我认为他不是个诚实的孩子。
I don't believe that will happen我相信那不会发生。
2. It moved at high speed and was really exciting!
它高速运动，确实令人兴奋！

3. Next, we hurried to a restaurant to have a quick meal.
接下来，我们匆匆去了一家餐馆吃了一顿简餐。
[考点点拨] hurry to someplace匆忙赶到某处；hurry to do sth. ＝be in a hurry to do sth＝do sth in a hurry匆忙做某事；in a hurry赶快，急忙。
Tom was still late though he hurried to school.
虽然汤姆匆匆赶到学校，但还是迟到了。
John is in a hurry to catch his train约翰急着赶火车。
4. On the way, we met some Disney cartoon characters, such as Snow White and-Mickey Mouse 在途中我们遇到了一些迪斯尼卡通人物，比如白雪公主和米老鼠。
[考点点拨]
(1) on the way在途中，在路上。后面可以直接跟地点副词home／here/there，跟地点名词时名词前要加介词to。其中the也可以换用形容词性物主代词。如：
Let's wait a few moments. He's on the way.
咱们等一会儿，他正在路上。
He lost his watch on his way to school this morning.
今天早晨他在去学校的路上丢了手表。
(2) such as例如，比如。一般用来列举同类人或物中的几个例子，插在被列举的例子和被列举的名词之间，as后没有逗号。如：
He has been to many countries, such as America,
Japan and Germany.他去过很多国家，比如美国、日本和德国。
such as后面不可以列出前面所提过的所有东西。如：
正：I know four languages, such as Japanese and English
我懂四种语言，如日语和英语。
误：I know four languages, such as Chinese, French, Japanese and English
我懂四种语言，如汉语、法语、日语和英语。
在现代英语中，such as可与etc.（等等）连用。如：
They planted many flowers, such as roses,
sunflowers，etc.他们种了许多花，如玫瑰、向日葵等。
[辨析] for example例如。一般只列举同类人或物中的一个为例，作插入语，不影响句子其他
部分的语法关系。可置于句首、句中或句末。如：
For example，air is invisible.例如，空气是看不见的。
He, for example, is a good student
例如，他就是个好学生。
三、重点语法
1．使用have/has been与have/has gone have/has been曾经去过，表示去过某地，现在已经回来了，人已经不在那里，指的是人的一种经历；have/has gone已经去了某地，表示人在途中或已经到达目的地，人不在说话者处，强调去某地还没有回来。两者后面可以直接跟地点副词，跟地点名词时名词前要加介词to。如：
- Where is Tom? 汤姆在哪里？
- He has gone to the bookshop.他去书店了。
(Tom在去书店的路上或已到书店，人不在说话处。)
- Where have you been recently? 你们最近去哪里了？
- We have been to Hong Kong.我们去香港了。
（人已回来，不在香港。）
Miss Brown has gone to Japan布朗小姐去日本了。

在上述含有一段时间的完成时句子中，主句中的谓语动词要用延续性动词。如：
I have had this bike for five years.
我买这辆自行车有五年了。
(3)延续性动词和短暂性动词
①英语中的动词可分为延续性动词和短暂性动词。延续性动词表示一个动作可以持续一段时间或更长时间，常见的有live，stay，study，play，read，write，sleep，talk，wait，fly，lie，walk等；短暂性动词表示一个动作发生在一瞬间，非常短暂，常见的有begin，start, finish, come, leave, find, get up, arrive, reach, get to, enter, hear, stop, open, close, become, buy, borrow, lend, happen, die等。
②延续性动词和短暂性动词都可用于完成时的句子中。但如果完成时句子中含有表示持续时间的时间状语，则要用延续性动词或相当于延续性动词的动词短语作谓语。有些短暂性动词也可转换为延续性的表达方式。如:
finish/stop-have/has been over; borrow-have/has kept;
leave-have/has been away; buy-have/has had;
die-have/has been dead: fall ill-have/has been ill;

三、重点语法
一般过去时和现在完成时的区别
一般过去时和现在完成时都可以表示过去发生的动作或存在的状态，但是在具体的语境中，它们有着明显的区别：
1．用法及强调的内容不同
(1)一般过去时表示过去某个时间发生的动作或存在的状态，着重陈述过去发生的事情或存在的状语，不涉及现在的情况。如：
I went to the park last Sunday.
上周星期天我去了公园。
（着重说明“上周星期天我去公园”这件事，和现在无关。）
(2)现在完成时常用于以下情况：
①表示从过去开始一直持续到现在的动作或状态，强调持续到现在。此时常和since…或for…连用。如：
Li Ming has lived in Nanjing since his family moved there in 2000.
自从2000年他家搬到南京，李明一直住在那儿。
（着重说明李明住在南京是从他家搬到南京开始一直持续到现在。）
She has been here for ten years.
她已经在这里十年了。
（着重说明她在这里从过去一直延续到现在十年了，而且还可能一直延续下去。）
②表示过去发生的动作对现在造成的影响或结果，强调对现在造成的影响或结果。此时常和already，yet，ever，just，never等连用。如：
I have had my breakfast already.
我已经吃过早饭了。
（“吃早饭”这个动作是过去发生的，对现在造成的影响是“我饱了，我不饿”。）
I have ever read this book
我曾经读过这本书。
（“读过这本书”这个动作是过去发生的，对现在造成的影响是“我知道这本书的内容”等等。）
2．连用的时间状语不同
现在完成时跟模糊的过去时间状语连用或不用时间状语；一般过去时通常跟具体的过去时间状语连用。常跟现在完成时连用的时间状语有：so far，in the past ten years, up to now, since…ago, for…, already, yet, ever, never, before, recently, lately等。
常跟一般过去时连用的时间状语：yesterday，last week，last year, last month, the day before yesterday, just now, in 1980等，如：
I have learned about 2, 000 English words so far.
到目前为止我已经学会了大约两千个英语单词。

8B Unit4
【考点精讲】
一、核心词汇

[考点点拨] Germany名词，意为“德国”。German作形容词，意为“德国（人）的”，作名词，意为“德国人”。常见的国家名称和某国人的单复数形式：
国家名称某国人单数某国人复数
Germany German Germans
America American Americans
Australia Australian Australians
Canada Canadian Canadians
France Frenchman Frenchmen
Frenchwoman Frenchwomen
England Englishman Englishmen

Japan Japanese Japanese
法国人、英国人复数形式是将a改为e，而德国人复数形式并不是将a改为e，中国人、日本人单复数形式相同。
2．stomach n．
[考点点拨]s tomach意为“腹部，胃”，虽然是以ch结尾，但是由于“ch”是发/k/音，所以其复数形式是在词尾直接加“-s”。如：
The stomachs of starving people often distend.
饥民的腹部常鼓得大大的。
3．either adv.
[考点点拨] either意为“也”，用于否定句，且要放在句末。如：
Millie can't skate. I can, t either.
米莉不会滑冰，我也不会。
too作“也”讲时，用于肯定句末尾，或作为插入语放在句中，前后用逗号隔开。如：Tom can swim. I can swim too.
汤姆会游泳，我也会。
You，too，may have a try.
＝You may have a try too.
你也可以试一试。
also在书面语中比too更为正式，用于肯定句中。紧靠谓语动词，位于be动词、助动词、情态动词后，行为动词前。如：
His uncle is also a policeman
他叔叔也是一名警察。
She is also reading a novel.
她也在看小说。
Sandy can also swim
桑迪也会游泳。
二、核心句型
1. Have you decided what to do with these books, Hobo?

[考点点拨] what to do with—how to deal with怎样处理。注意疑问词what和动词do搭配，疑问词how和动词deal搭配。如：

I have a huge pile of letters to deal with
我有一大堆信件要处理。
2. However, they soon got up again and continued moving across my body．

[考点点拨]continue doing sth继续做某事，也可以说continue to do sth，两者意思相同：如：They continued meeting every day.
＝They continued to meet every day.
他们继续每天见面。
表示继续维持某一情况时，其后可直接跟名词作宾语，也可先接介词with再接宾语。如：We will continue (with) the payments for another year.
我们这样的报酬还要维持一年。
continue doing sth.意为“继续做某事”，continue by doing sth.意为“接着做某事（其他事）”。如：
He continued reading/to read all night.
他通宵在看书。
He talked about Keats, and continued by reading us a poem
他谈了济慈，接着给我们朗诵了一首诗。
三、重点语法
1．特殊疑问词+动词不定式
(1)“特殊疑问词+动词不定式”结构相当于一个名词，在句子中可作主语、宾语、表语、宾语补足语、状语、同位语等句子成分。大部分特殊疑问词可用于该结构，如when，how，which，where，who等等。注意：疑问词why不能用于该结构。如：
Where to go is still a question
去哪里还是个问题。
（作主语；作主语时，谓语动词常用单数形式）
I know where to find the boy.
我知道哪里能找到这个男孩。
（作动词know的宾语）
The question is how to learn English well.
问题是怎样学好英语。（作表语）
The question where to spend this weekend troubles Millie．
到哪儿去过周末这个问题困扰着米莉。（作同位语）
连词whether也可以用于该结构。如：
They are talking about whether to have a party.
他们正讨论是否要举办一场聚会。（作宾语）
(2)“特殊疑问词+动词不定式”结构经常用在某些动词（短语）后面作宾语，常见的有tell，show，know，learn，teach, find out, forget, wonder, remember等。如：
I'll show you how to do it.
我会让你看看如何做这件事。
“特殊疑问词+动词不定式”结构还可以用在be sure，
be clear等后面作宾语。
I'm not sure when to leave.
我不确定何时出发。
(3)“特殊疑问词十动词不定式”结构可以把复合句转换为简单句。如：
I don't know what I'll do next.
＝I don't know what to do next.
我不知道下一步该做什么。
反之可以将含有“特殊疑问词十动词不定式”结构的简单句转换为复合句。改写时只需在疑问词后加上适当的主语，并把不定式改为适当形式的谓语即可。如：
Li Ping doesn't know how to learn English
＝Li Ping doesn't know how he should learn English
李平不知道该怎样学英语。
(4)“特殊疑问词+动词不定式”结构可以独立成句。如：
What to do?
怎么办？
How to get rid of the trouble?
如何摆脱困境？
(5)常见的两类错例
①动词后面要不要加介词？如：
我还没决定住哪儿。
误：I haven't decide where to live in.
正：I haven't decide where to live.
注：where是疑问副词，副词前不需要加介词。可以说live there，live in the flat，不可以说live in there，live the flat。
②动词后面要不要宾语？如：
我不知道该做什么。
误：I don't know what to do it.
正：I don't know what to do.
注：这里不要it，因为前面的what就是do的逻辑宾
语，it在这里多余。
我不知道怎样去做。
误：I don't know how to do．
正：I don't know how to do it.
注：这里要it，因为do是及物动词，后面需要宾语，而how是疑问副词，不能作动词do 的宾语，它在这里作状语，所以这里需要it。
2．must和have to
must表示主观的意愿或命令，语气强烈。其否定形式为mustn't，意为“禁止，不可以”；have to表示客观的义务或需要，意为“必须，不得不”，其否定形式为don't have to，表示“不必，不需要”，一般现在时中主语为第三人称单数时则要用has to，doesn't have to。如：
We students must work hard.
我们学生必须努力学习。
My bike is broken today. I have to walk to school.
今天我的自行车坏了，我不得不步行上学。
- Must I stay here?
我必须留在这儿吗？
- No, you needn't.／No, you don't have to.
不，不必。

【考点精讲】
一、核心词汇
1．turn n．
[考点点拨] turn作名词，意为“轮流，（轮流的）顺序”。
It's one's turn to do sth.轮到某人做某事了。如：
It's my turn to clean the blackboard.
轮到我擦黑板了。
It's your turn to throw the ball.
轮到你投球了。
take turns to do sth.轮流做某事。如：

请轮流提问。
by turns轮流地，相当于一个副词，在句中作状语。如：
They take turns to look after the boy.
＝They look after the boy by turns.
他们轮流照顾这个男孩。
2．avoid vt．
[考点点拨] avoid意为“避免”，是及物动词，后面可以接名词、代词或动名词作宾语，但是不能接动词不定式作宾语。如：
He brakes his car just in time to avoid an accident.
他及时煞车，避免了一场事故。
I want to avoid it at all costs.
我想要不惜任何代价来避免它。
他避而不答我的问题。
正：He avoided answering my questions.
误：He avoided to answer my questions.
3．till conj．
[考点点拨] till意为“到……时，直到……为止”。till和until都可以用作介词或连词，一般情况下两者可以互换使用。用于肯定句时，主句的动词只用延续性的，它所表示的动作一直延续到till／until表示的时间为止，意为“直到……为止”；用于否定句时，主句的动词一般是非延续性的，也可以是延续性的，它所表示的动作直到till／until所表示的时间才发生，意为“直到……（才）”。如：
She watched TV until/till her mother came back
她一直在看电视，直到她母亲回来。
（看电视的动作延续到母亲回来才结束。）
She didn't watch TV until/till her mother came back
直到她母亲回来她才（开始）看电视。
（看电视的动作直到她母亲回来才发生。）
如果要放在句首，只能用until而不能用till。如：
误：Till I finished my homework, Mother didn't let me out.
正：Until I finished my homework, Mother didn't let me out.
直到我做完家庭作业妈妈才让我出去。
二、核心句型
1. Second, don't cut in on others.
第二，别打断别人的话。
[考点点拨] cut in on sth /sb.打断某物／某人的话，插嘴。如：
Don't cut in on your mother when she is speaking.
你妈妈讲话时，不要插嘴。
Don't cut in on other people's conversation
别打断别人的谈话。
2. Always keep the library clean.
要一直使图书馆保持干净。
[考点点拨]“keep sb./sth+形容词”意思是“使某人／某物保持……”，其中的形容词是宾语sb. /sth.的补足语。如：
It is very important to keep ourselves healthy.
使我们自己保持健康是很重要的。
I'd like to keep myself busy.
我愿意让自己一直忙碌。
3…. and shake your hand when they meet you for the first time.
……并且当他们第一次见到你的时候会和你握手。
[考点点拨]shake是不规则动词，过去式是shook，过去分词是shaken。shake one's hand和某人握手。如：
He came up to me and shook my hand.
他走上前来和我握手。
A stranger walks up to me and shakes my hand.
一个陌生人向我走来并同我握手。
4. If you're in their way, they won't touch you or push past you
如果你挡住了他们的路，他们不会碰你或从你身边挤过去。
[考点点拨] in one's way妨碍某人；挡住某人的路。不需要说明某人时也可以用in the way。如：
Sorry，you're in my way．
对不起，你挡着我的路了。
A fallen tree was in the way.
一棵倒下的大树挡住了去路。
on the/one's way to someplace在（某人）去某地的路上／途中；某地用副词表示时不要介词to。如：
Millie is on her way to school now.
米莉现在正在去学校的路上。
I bought a magazine on my way home yesterday evening.
昨晚我在回家的路上买了一本杂志。
by the way顺便说／问一下。如：

顺便问一下，你爷爷奶奶身体好吗？
5. British people are very polite at home as well, aren't they?
