the other 指两个人或事物中的“另一个”,表示特指?如:We stood on one side of the road and they stood on the other. 我们站在街这边,他们站在那边
another着重于不定数目中的“另外一个”,表示泛指,所以常用来指至少三个中的一个?如:She has taken another of my books. 她已经拿了我的另外一本书

between 的意思是“在……中间,在……之间”,一般指在两者之间?如:There is a table between two windows. 在两扇窗户之间有一张桌子。between 有时也表示在多于两个以上的事物之间,但那是指在每二者之间。如:the relationship between different provinces and municiplities 省市和省市之间的关系(这里是指每两个省市之间的相互关系?)

none指“一个也没有(既可指人,也可指物)”,作主语时代替不可数名词,谓语动词用单数形式;代替可数名词,谓语动词用单、复数都可以。但在“主+系+表”结构中,如果表语为复数,则系动词要用复数形式。如:None of us are(is) afraid of difficulties. 我们谁也不怕困难。

in the front of的意思是“在……前部”,指在某个空间范围内的前面。如:There is a blackboard in the front of the classroom. 教室里前部有一块黑板
16. noise, voice, sound
这三个词都作“声音”解,在表示“听到声音”这个意思时,三者可以通用,但它们又各有特定的含义。
sound 作“声音”解,含义最广,指可以听到的任何声音,如:a weak sound 微弱的声
noise作“噪音,嘈杂声,吵闹声”解,指不悦耳,不和谐的声音,它既可作可数名词,也可作不可数名词。如:Another kind of pollution is noise. 另外一种污染是噪音。

get之后通常接介词to。如:When we got to the park, it began to rain. 我们到达公园时,就开始下雨了。

1.考查情态动词表示“推测”的用法

2.考查情态动词引起的一般疑问句的答语
[考点快忆] 回答must时,肯定答语用must,否定答语用needn't或don't have to。回答need时,肯定答语用must,否定答语用needn't。回答may时,肯定答语用may,否定答语用mustn't 或can't。
3.考查情态动词的意义
[考点快忆] must “必须”;have to“不得不”; need “必须;需要”; can(could)“能;可能”;may (might) “可以;可能”; shall,will (would)“将;会;愿意;要”; should“应当”。
“had better (not) + 动词原形”表示建议;have to / has to / had to的否定,疑问形式要借助于助动词do / does / did。
There be是一个“存在”句型,表示“有”的意思,
肯定句的形式为:There be + 名词(单数或复数)+地点状语或时间状语。
be动词单复数的确定,看be后边第一个名词,当所接主语为单数或不可数名词时,be动词形式为is;当所接主语为复数名词时,be动词为are;当be动词后接两个以上主语时,be动词与最临近主语保持数上的一致。意思为“某地有某人或某物”。如:
There is an eraser and two pens on the desk. 桌子上有一块橡皮和两支钢笔。
There are two pens and an eraser on the desk. 桌上有两支钢笔和一块橡皮。

(2)there be句型的疑问句就是将be提到句首:Be there + (any) +名词+地点状语

-Are there any boats in the river?河里有船吗
-No, there aren't. 没有。
(3)特殊疑问句:How many . . . are there (+地点状语)
某地有多少人或物回答用There be . . .
There's one. / There are two / three / some . . .
有时直接就用数字来回答。One. / Two . . .
-How many students are there in the classroom?教室里有多少学生
-There's only one. / There are nine. 只有一个。/有九个。
(4)如果名词是不可数名词,用:How much + 不可数名词 + is there + 地点状语
How much water is there in the cup?杯中有多少水
1.定语从句的功用和结构
在复合句中,修饰某一名词或代词的从句叫做定语从句。被定从句修饰的词叫做先行词。定语从句必须放在先行词之后。引导定语从句的关联词有关系代词和关系副词。例如:
This is the present that he gave me for my birthday
2.关系代词和关系副词的功用
关系代词和关系副词用来引导定于从句,在先行词和定语从句之间起纽带作用,使二者联系起来。关系代词和关系副词又在定语从句中充当一个成分。关系待客做主语,宾语,定语,关系副词可作状语。
1. 作主语:关系代词在定语从句中作主语时,从句的谓语动词的人称和数须和先行词一致。例如:
I don’t like people who talk much but do little.
The cars which are produced in Hubei Province sell very well.
2. 作宾语:She is the person that I met at the school gate yesterday.
The book that my grandmother gave me is called “The Great Escape”.
3. 作定语
关系代词whose在定语从句中作定语用。例如:
What’s the name of the young man whose sister is a doctor?
The girl whose father is a teacher studies very hard.
4. 作状语
I’ll never forget the day when I first came to Beijing.
三. 各个关系代词和关系副词的具体用法
1. who 指人,在定语从句中作主语。例如:
The person who broke the window must pay for it.
The boy who is wearing the black jacket is very clever.
2. whom指人,在定语从句中作宾语。例如:
Do you know the young man (whom) we met at the gate?
Mr Lee (whom) you want to see has come.
3. whose 指人,在定语从句中作定语。例如:
The girl whose mother is ill is staying at home today.
I know the boy whose father is a professor.
4. which指物,在定语从中作主语或宾语。例如:
A dictionary is a book which gives the meaning of words.
Here is the book (which) the teacher mentioned yesterday.
5. that多指物,有时也指人,在定语从句中作主语或宾语。例如:
I’ve read the newspaper that(which) carries the important news.
Who is the person that is reading the newspaper over there?
6. when 指时间,在定语从句中作状语。例如:
I’ll never forget the time when we worked on the farm.
He arrived in Beijing on the day when I left.
7. where 指地点,在定语从句中作状语。例如:
This is the house where we lived last year.
The factory where his father works is in the east of the city.
四. 关系代词 whom, which 在定语从句中作介词宾语时,可以和介词一起放于先行词与定语从句之间,有时为了关系紧凑也可以将 whom 与 which 与先行词紧挨着书写,而将介词置于定语从句的后面,如:
That was the room in which we had lived for ten years. = That was the room
which we had lived in for ten years.
五. 具体使用时还要注意下列问题:
1. 只能使用that,不用which 的情况:
(1) 先行词是all, few, little, nothing, everything, anything 等不定代词时。例如:
All that he said is true.
(2) 先行词被only, no, any, all,等词修饰时。例如:
He is the only foreigner that has been to that place.
(3) 先行词是序数词或被序数词修饰的词。例如:
He was the second (person) that told me the secret.
(4) 先行词是形容词最高级或被形容词最高级修饰的词。
This is the best book (that) I have read this year.
(5) 先行词既包括人又包括物时。例如:
He talked about the people and the things he remembered.
2. 只能用which,不用that 的情况:
(1) 在非限制性定语从中。例如:
The meeting was put off, which was exactly what we wanted.
(2) 定语从句由介词+关系代词引导,先行词是物时。例如:
The thing about which he is talking is of great importance.
考查的主要形式是单项填空、完型填空、短文填空和完成句子。阅读理解和书面表达肯定也要用到定语从句。
