【中考重点短语】
the number of意为“……的数量”，后接可数名词复数，作主语时，谓语动词用单数形式，表语常是数词，也可接large，small作表语
a number of 意为“许多的”，相当于many，修饰可数名词复数，作主语时，谓语动词用复数形式。number前可加small，large，great表示程度,即a large number of “大量的”， a small number of “少量的”

【答案】
1.The number of the students in our school is 2000.
2.A number of students are playing on the playground.
3.C
4.A
5.are
6.play
7.is
8.A
解析：根据题意，本句是有许多鹿，许多是a number of。Deer的用法是单复数同形。中考时，有三个单复数同形的单词，必须要记住：鱼鹿羊（谐音于露洋，一个美丽的小女孩），fish，deer，sheep。
9.C
解析：第一空，句子里的动词是like，是原形，不是三单，因此用a number of。如果是the number of，谓语动词一般来说都应该是is，rises，increases这类词汇。第二空就是分数的用法：子基母序的规则，也可以把fifth看成五分之一，那么五分之四就是四个五分之一。因此fifth用复数。
三、look like, be like和feel like 的区别
like最常用作【v.】和【prep】
①作动词，“喜欢”
②作介词，“像”，“类似”，“...怎么样”
注意下面两个高频表达:
How do you like your teacher
= What do you think of your teacher
你认为你的老师怎么样
What is the weather like in Chongqing
= How is the weather in Chongqing
重庆的天气怎么样
短语辨析:
look like “看上去像”，指外观上像。
be like “像……一样”，指品德、相貌等，更多侧重表示人的个性特征。
feel like意为“想要(做某事)”，feel like doing sth.=want to do sth., 其后接名词或动名词，不能接不定式。
feel like 还表示 “摸起来好像”， 因为feel是系动词， 表示“摸起来”，“感觉到”
如:
She looks like her mother.
她看起来像她妈妈。
--What is he like 他是个什么样的人
--He is kind and warm-hearted.他善良又热心。
I feel like a cup of tea.
我想喝杯茶。
Do you feel like joining us
你想要加入我们吗？
I like this scarf.It feels like silk.
喜欢这条围巾。 它摸起来像丝绸。
四、think相关短语
think about 意为“想，考虑”，指考虑解决某一问题,“考虑”的宾语可由名词、代词、动名词、疑问词引导的不定式或宾语从句充当。
think of 意为“思考，想起，考虑”。表示“考虑”的含义时，可与think about互换，后接名词、代词、v.-ing形式或疑问词引导的从句。
think over 意为“仔细考虑”，其中over为副词，如宾语为名词，位于over前后均可，如果是代词，必须置于think与over 之间。
【练习】
1.我正在考虑一个问题。（汉译英）
2.He always thinks of others more than himself.（英译汉）
3.在你做这件事之前，你最好先好好考虑一下。（汉译英）
4.This is my idea.I hope you can _______ it.
A.Think of
B.Think over
C.Think about
D.Think up
5.选词填空:think of，think about 和 think over

--It's very good.It is clean and beautiful.
②.--Would you like to go abroad to study
--Let me_____it_.
【答案】
1.I'm thinking about a problem.
2.他总是为别人考虑得多，为自己考虑得少。
3.You'd better think it over before you do it.
4.C
5.①think of
②think; over
五、leave相关短语
leave “离开，出发”，其后接表示地点的名词，构成“leave+地点名词”短语。
leave for 后接表示地点名词表示“动身去某地”。
leave...for...表示“离开某地去另一地”， 即leave A for B。
leave from “从……离开”，from后的地点是离开的地方。
如:
When did you leave London
你们是什么时候离开伦敦的
We are leaving for Rome next week.
我们下周将要去罗马。
We will leave Beijing for Shanghai.
我们将要离开北京去上海。
I'm leaving from school.

【答案】
