三、教材精华
1．He could be running for exercise．他跑步可能是为了锻炼身体。
(1)could be running是“情态动词+ be + doing”结构，表示猜测正在进行或发生的动作。
I think he could be watching TV at home．我想他可能正在家里看电视。
(2)exercise
①本句中exercise作“运动；锻炼”讲，是不可数名词，do／take exercise=do sport，意为“进行运动；锻炼身体”。He takes exercise every day．他每天都运动。
②当exercise作“体操；练习”讲时，是可数名词。do morning／eye exercises做早操／眼保健操
③exercise作不及物动词，意为“运动；练习”；作及物动词，意为“使……得到锻炼”。
We exercise every morning．我们每天早晨都锻炼。
She was exercising herself in singing．她在练习唱歌。
2．He might be running to catch a bus．他也许是跑着去赶公共汽车。
catch动词，意为“捕获；赶上”。过去式、过去分词均为caught。
The cat caught a mouse．那只猫逮到了一只老鼠。
He ran quickly to catch the bus．为赶上公共汽车他飞快地跑。
［图解助记］catch的一词多义
3．When he was interviewed by the local newspaper, he said,“Every night we hear strange noises outside our window…”当地报社采访他时，他说：“每天晚上我们都听到窗外奇怪的声音……”
(1)interview动词，意为“面试；采访；会见”。
We are going to interview the manager of this company．我们要采访这家公司的经理。
He has interviewed a lot of people for the job．关于这份工作，他已面试过很多人。
［图解助记］interview，interviewee与interviewer
动词后加上后缀—ee／—er，成为名词，表示该动作的承受者／发出者。
train trainer trainee 训练 训练人 受训者
employ employer employee 雇用 雇主 雇工
examine examiner examinee 考试 主考人 应试者
(2)noise名词，意为“噪音；喧闹声；嘈杂声”。
I don't like so much noise．我不喜欢如此吵闹。
I heard a noise in the next room．我听到隔壁房间里有嘈杂声。
温馨提示
noise作“噪声”“喧闹”讲时，为不可数名词；而作“某种声音”讲时为可数名词。
. Stop making so much _____. The children are sleeping.
A. voice B. noise C. sound
答案：B
【解析】本题考查词义辨析。voice一般指人的声音，说话、唱歌。谈笑都可用voice。noise意为“噪音”、“喧闹声”，常指不悦耳、不和谐的嘈杂声。sound作“声音”，“响声”讲时，可以指人或动物发出的声音，或物体碰撞的声言。这个词的使用范围很大。可以说，大自然的任何“声音”都可以用sound。句意“不要制造那么大的噪音，孩子们正在睡觉”。根据句意可知用noise。故选B。
. — Did you hear any strange _____when the quake happened?
— No, I was in my garden with my flowers and was enjoying the beautiful _____of my birds at that time.
A. voice; noise B. noise; sound C. whisper; sound D. sound; voice
答案：D
–Lily has a silk __________. Listen, she is singing in the next room!
-- How nice!
A. look B. noise C. voice
答案：C
【解析】名词词义辨析。look可数名词，意思“相貌，样子，外表”，常用复数形式；noise 不可数名词，意思“噪杂声，吵闹声”；voice，可数名词，意思“嗓音，说话声”。故选择C。
(2008·安徽中考) The music made me think of the ________ of a running stream.
A. shout B. noise C. voice D. sound
【解析】选D。考查“声音”的区别。根据题意“这种音乐让我想起来机器运转声”可确定D为正确答案。
4．There must be something visiting the homes in our neighborhood…
一定有某种东西闯入了我们的小区……
(1)there must be是there be句型与情态动词must连用，表示对现在情况的肯定推测，意为“一定有……”。
There must be someone in the room．房间里一定有人。
注意
①由there must be构成的句子，如果must表推测，意为“一定是，必须”，其反意疑问句则需要根据be来选用适当形式，即be + not + there?
There must be a knife in your pocket，isn't there?
你的口袋里一定有把小刀，不是吗?
There must be some people in the room，aren't there?房间里肯定有一些人，是吗?
②there be句型除有现在时态和过去时态形式外，还可以有完成形式，其结构为“There have been+名词”。
There have been great changes in our hometown in the last few years．
在过去的几年里我们家乡发生了巨大的变化。
(2)“There be+名词十doing”句型表示“有……在进行”。
There is someone knocking at the door．有人在敲门。
5．No more mystery in Bell Tower neighborhood钟楼小区不再神秘
该句是一个省略句，完整的句子应是There is no more mystery in Bell Tower neighborhood．其中no more意为“不再”，表示动作不再出现，相当于not...any more，可以和表示短暂动作的动词连用。
Time lost will return no more．时光一去不复返。
6．We now know what was happening in Bell Tower neighborhood．
现在我们知道钟楼小区发生什么事情了。
辨析：happen与take place
happen
“(偶然)发生”，较多地用来指某个事件的突然发生，强调其偶然性，主语往往是事件、事故等名词。其后也可接动词不定式，多用于It happens that．．．结构，表示“碰巧”的意义。happen to do sth．“碰巧做某事”。
take place
“发生，举行”，常指某事按规律、预先布置或按计划发生或进行，尤指“举行”，不含偶然的意味。用表示具体事物的名词作主语时，有时可以和happen交换使用。
If anything happens to the machine，please let me know．
如果机器出了什么毛病，请通知我。
The sports meeting took place(＝was held)in our school last week．
上周我们学校举行了一场运动会。
7．The director of the local zoo says that three monkeys escaped from…
当地动物园的主管说3只猴子从……逃跑了。
(1)director是由动词direct(指导，指挥)加后缀—or构成的名词，意为“主管，主任；导演”。
The director of the film is Feng Xiao gang．这部电影的导演是冯小刚。
She is a director in the company．
她在这家公司做主管。
(2)escape动词，意为“逃跑，逃走”，常与from，out of连用，表示“从……逃跑／逃走，逃离……”。
They escaped from the burning house．他们从那座着火的房子里逃了出来。
8．In my dream, I was swimming in an ocean of paper．
在我的梦中，我在试卷的海洋里遨游。
ocean海洋，大海;[喻]无限，无际;[常用复数]大量，许多。本句中an ocean of=
oceans of，后可跟可数或不可数名词，意为“极多的，无边际的，大量的”。
I saw an ocean of ants moving to a new place．
我看见很多的蚂蚁正在搬往一个新地方去。
