三、重点知识点讲解：
考点（一）词语辨析
Ⅰ. in front of / in the front of 辨析
in front of 是在整个物体的前面，in the front of 是在物体内部的前面。
例如：a tree is in front of the classroom是教室前面有棵树，树一般在教室外面的户外；
there is a desk in the front of the classroom就是教室前面有张桌子，（比如讲台）是在教室里面的，这是内部方位。
【典型例题1】1.The teacher’s desk is _______________ our classroom and our English teacher likes standing _______________ it .
A. in front of, in the front of
B. in front of , in front of
C. in the front of , in front of
D. in the front of , in the front of

A. in front of; in the front of
B. in front of; in front of
C. in the front of in front of
D. in the front of; in the front of
【答案】A
【解析】
考点：考查固定短语的辨析。
Ⅱ. get/ reach/ arrive辨析
1. 三者均可表示“到达”。注意：arrive 和get 都是不及物动词，前者较正式，后者较口语化。两者之后均不可接宾语，但可接here, there home 之类的表地点的副词作状语。如：
When did you arrive?　你什么时候到的？
We got (arrived) here last night. 我们昨晚到这儿。
2. reach (到达)是及物动词(属较正式用语)，其后可直接跟地点名词作宾语(不能用介词)，也可接here there home 等词。如：reach Beijing (到达北京)；reach home (到家)。
3. 表示“到达某地”，可在地点名词之前reach, get to或 arrive in / at (in 一般用于较大的地方，at 用于较小的地方)。如：
They reached (或got to / arrived at)the station on time. 他们准时到达车站。
【典型例题2】1.A: Could you tell me when you will _______Tokyo?
B: I’m not sure. When I _______ I will call you.
A．arrive ; reach B．reach; get to C．get to; arrive D．reach; arrive at
【答案】C
【解析】表到达，有三种方式：arrive，reach或get to。Reach后面必须跟宾语，arrive后面跟宾语须加介词 at 或 in，get 后跟宾语要加 to，所以第一空可用reach 或get to，第二空用arrive 。所以选C。
考点：考查动词的用法。
2.“When will your father _________ Shanghai?” “He ________ at 8:00 this Monday.”
A. arrive at, will arrive B. arrive in , will arrive
C. arrive ,will arrive in D. arrive, will arrive at
【答案】B
【解析】
考点：考查动词时态
Ⅲ. join/join in/take part in辨析
1. join 表示从参加某一团体并作为其中一员,如果后接人,则表示参加某人的活动,如: Let's join the children. 我们去参加孩子们的活动.
2. join in 指参加到某些人当中去做某事,这项活动往往正在进行着,如: May I join in the game? 我可以参加这个游戏吗?
3. take part in指参加会议或者群众性的活动等,重在说明句子的主语参加该项活动并在活动中发挥作用,如: John takes part in many school activities. 约翰参加很多学校里的活动
附加: take part in是参加某种活动 take a part in 在……中扮演某个角色
【典型例题3】1. Why don’t you _____ us to _____ the speech contest?
A. join, join B. take part in, take part in
C. take part in, join D. join, take part in
【答案】D
【解析】考查近义词辨析。join指参加活动时，后加介词in；join后可直接+人或组织；take part in指参加大型活动，并在活动中其积极作用。句意“为什么不加入我们一起参加演讲比赛呢？”后加人作宾语用join；排除B、C；join不能直接加活动，排除A。故选D。
2. —Where are you going, Jack?
—I’m going to _______ the English corner. Would you like to _______ me?
—I’m afraid I can’t.
A. take part in; join B. join; take part in
C. join; join in D. join in; take part in

【答案】A
【解析】
试题分析：句意：杰克，你要去哪里？我要去参加英语角。你愿意和我一起去吗？take part in指参加群众性活动、会议、劳动、游行等，往往指参加者持有积极的态度，起一份作用；join指加入某党派、某组织或某社会团体，以及参军等，还可表示参与某种活动。"与某人一起做某事"则用join sb. in sth./doing sth.。故选A。

考点（二）语法重点
过去进行时态
过去进行时态

② 过去某段时间正在发生的动作
I was staying here from March to May last year. 去年从3月到5月，我一直呆在这里。
⑵ 与过去进行时连用的时间状语，常见的有 at nine last night/at that time=then/at
this time yesterday/或有when the teacher came in/ while he was reading的提示
⑶ 过去进行时的构成：was\were +现在分词
⑷ 过去进行时的四个基本句型
肯定句 He was cooking at six last night.
否定句 He was not cooking at six last night.
一般疑问句 Was he cooking at six last night?

when 和while的区别
when，while，显然都可以引导时间状语从句，但用法区别非常大。
一、when可以和延续性动词连用，也可以和短暂性动词连用；而while只能和延续性动词连用。
① Why do you want a new job when youve got such a good one already？get为短暂性动词）你已经找到如此好的工作，为何还想再找新的？
②Sorry，I was out when you called me．（call为短暂性动词）对不起，你打电话时我刚好外出了。
③Strike while the iron is hot．（is为延续性动词，表示一种持续的状态）趁热打铁。
④ The students took notes as they listened．（listen为延续性动词）学生们边听课边做笔记。
二、when从句的谓语动词可以在主句谓语动作之前、之后或同时发生；while从句的谓语动作必须是和主句谓语动作同时发生。
1．从句动作在主句动作前发生，只用 when。
①When he had finished his homework，he took a short rest．（finished先发生）当他完成作业后，他休息了一会儿。
②When I got to the airport，the guests had left．（got to后发生）当我赶到飞机场时，客人们已经离开了。
2．从句动作和主句动作同时发生，且从句动作为延续性动词时，when，while都可使用。
①When ／While we were dancing，a stranger came in．（dance为延续性动词）当我们跳舞时，一位陌生人走了进来。
②When ／While she was making a phonecall，I was writing a letter．（make为延续性动词）当她在打电话时，我正在写信。
3．在将来时从句中，常用when，且从句须用一般时代替将来时。
①You shall borrow the book when I have finished reading it．在我读完这本书后，你可以借阅。
②When the manager comes here for a visit next week，Ill talk with him about this．下周，经理来这参观时，我会和他谈谈此事。
