3、，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”【练习】1.我们学校的学生人数为2000。（汉译英）2.许多学生正在操场上玩耍。 （汉译英）3.-How many boys are there in your class?-_them_twenty three.A.A number of; are B.The number of; are C.The number of; is D.A number of; is4._books on the shelf is about one thousand and _them are on sale.A.The number of;a number of B.The number of;the number of C.A number of;the number

5、e number of the students in our school is 2000.2.A number of students are playing on the playground.3.C4.A5.are6.play7.is8.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thenumberof，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】作动词，“喜欢”作介词，“像”，“类似”，“.怎么样”注意下面两个高频表达:How do you like your teac

6、her?= 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 s

7、carf.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 ofB.Think over C.Think aboutD.Think up5.选词填空:think of，think about 和 think over -What do y

8、ou _our school?-Its very good.It is clean and beautiful.-Would you like to go abroad to study?-Let me_it_.【答案】1.Im thinking about a problem.2.他总是为别人考虑得多，为自己考虑得少。3.Youd better think it over before you do it.4.C5.think of think; 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。 Im leaving from school.我要从学校离开。【练习】1.My father _ the city of New York three days ago.A.leaveB.left toC.left offD.left for用leave和leave for 的适当形式填空。2.Remember to close the door when you _ the house.3.He_ Beijing this morning, and will arrive there in an hour.【易错题】4.My father _ the USA in two weeks.A.is leave forB.leavesC.is leaving forD.left for【答案】1.D2.leave3.
