Exercises
Say out the PP of the verbs.
1、You used to share food with me.
used to do sth."过去常常做某事"，暗含"现在不再"之意，后接动词原形，疑问形式可以直接将used提到句首，或者借助助动词did;否定式可以直接在used后面加not，或者用didn't。
used to do sth. "过去常常做某事" 例如∶I used to go to school by bus.
be/get used to doing sth. "习惯于做某事" 例如∶I am used to living here now.
be used to do/for sth. "被用来做某事" 例如∶A pencil is used for writing.
直击重难点
例. He used to_______ games on the Internet，but now he gets used to_______ a walk after supper.
A. play; taking B. playing; take C. play; take D. playing; taking
【分析】他过去常常上网打游戏，但现在他习惯于饭后散步。
【解答】答案∶A used to do sth过去常常做某事，后面跟to引导的不定式短语; be/get used to doing sth习惯于做某事，后面跟动词的ing形式，根据He used to_____ games on the Internet, but now he gets used to_____a walk after
supper，可知第一个空用used to do sth，第二个空用be/get used to doing sth。故选A
【点评】本题考查了动词的固定搭配。解答时注意∶used to do sth过去常常做某事，后面跟to引导的不定式短语;be/get used to doing sth习惯于做某事，后面跟动词的ing形式。
【例题拓展】
She________a bike to school, but now she_______to school.
A. used to ride; is used to walking B. used to riding; is used to walking
C. is used to riding; used to walk D. is used to ride; used to walking
【分析】她过去常常骑自行车去学校，但是现在她习惯于步行去学校。
【解答】答案∶A 考查动词的固定搭配。句意"她过去常常骑自行车去学校，但是现在她习惯于步行去学校。"used to do sth表示过去常常做某事;be used to doing sth表示习惯于做某事。故选A
【例题拓展】
-Jinan ______be small and dirty.
-I agree. But great changes have taken place since the National Games was held.
A. is used to B. is used for C. is used by D. used to
【分析】-济南过去即小又脏。-我同意你的说法。但自从举行了全运会以来，发生了巨大的变化。
【解答】答案∶D 根据But great changes have taken place since the National Games was held，可知济南发生了很大的变化，前面应该说的是过去怎么样，used to do sth过去常常做某事或怎么样。故选D
2、Why didn't you take a bus
take+a/the+表示交通工具的名词，在句中作谓语。
by+表示交通工具的名词，或者介词in/on+表示交通工具的名词，在句中作状语。
例如∶He takes a bus to school. = He goes to school by bus.
（改编自2022·湖南湘西）It only takes us two hours to go from Jishou to Changsha _______ when Zhang-Ji-Huai high-speed railway opened in December last year.
A．take a train B． by train C．took a train

3、Well, there were always too mamy people on the bus and it took a long time to wait for the next one.
1) too many意为"太多"，修饰可数名词复数。例如∶There are too many books in the box.
too much同样表示"太多"，修饰不可数名词。例如∶I have too much homework to do today.
much too意为"太"，用来修饰形容词和副词，表示程度。例如∶It's much too hot today.

4、I've lived here since I was born.
since作连词，表示“自………以来”，引导时间状语从句时，从句用含有一个过去时间点或过去时的从句，主句用现在完成时。
例如∶He has worked in this company since he graduated from college.
since也可以用作介词，后面加上表示过去的时间点，同样和现在完成时连用。
例如∶The family have lived here since three years ago.
has taught
came
如：
He _________ (teach) English at this school since he ______ (come) to China.
自从他来到中国就到这所学校教英语。
例. -Will you watch the program Running Man in Zhejiang Star
-TV tonight -Yes,of course. It________one of the most popular shows since last October.
A. was B. became D. has become C. has been
【分析】-你要看浙江卫视的节目《奔跑吧!兄弟》吗 - 是的，当然。从去年十月以来它就是最受欢迎的节目之一了。
【解答】答案∶C 根据since last October可知，"自去年十月"表示一段时间，表示过去的动作一直持续到现在，应该用现在完成时态;现在完成时态的结构为have/has+动词的过去分词，而become是瞬间性动词，不能持续一段时间，所以要用延续性动词be，表状态。故选C
例. My brother_______interested in English since the end of last term.
A. had become B. became C. was D. has been
【分析】我哥哥从上学期末就开始对英语感兴趣了。
【解答】答案：Ｄ。考查现在完成时态。句意“我哥哥从上学期末就开始”。Ａ过去完成时态。Ｂ过去式。Ｃ过去式。Ｄ现在完成时态。根据since the end of last term从上学期末。可the end of last term从上学期末。可知，since＋表示过用于现在完成时态。结构是have/has+动词的过去分去的时间点，通常用于现在完成时态。结构是词。be interested in对.....感兴趣。be的过去分词是been。答案是D。
【点评】现在完成时态，由“have/has＋过去分词”构成，表示动作发生在过去，但与现在的情况有联系。也表示从过去某一时续到现在并还可能继续延续下去的动作。结合语境续延续下去的动作。结合语境，注意人称变化及动词过去分词变化。
【例题拓展】
I became a teacher ten years_____. I have been a teacher________1996. I have worked here about 10years.
A. ago; since; for B.ago; for; since C. ago; before; for D. ago; in; after
【分析】十年前我成了一名老师，自从1996年我就是一个老师了，我已经在这儿工作大约10年了。
【解答】答案∶A 考查连词辨析。根据句意∶十年前我成了一名老师，自从1996年我就是一个老师了，我已经在这儿工作大约10年了。ago用于过去时，since+时间点，for+时间段，用于现在完成时，故选A。

6、When I got married in 1965, my wife and I moved two blocks away and we've lived in this area since then.

8、It's really nice to have a beautiful modern town.
形式主语it的用法。
在英语中，当动词不定式或者that从句作主语时，常用it作形式主语，把真正的主语动词不定式或者that从句置后。it处于主语的位置，但不是真正的主语，因此英语中称之为形式主语。
常用的结构为∶It is+形容词/名词短语+to do/that从句。
e.g: It is important to learn English well.
It is a hard job that he cleans the street day and night.
注意∶"It is+形容词/名词短语+to do"结构中，当形容词是描述人的性格、品质的形容词时，用介词of，其余情况用介词for。e.g: It is kind of you to help me a lot. / It is difficult for us to solve the problem.

9、Now I feel a bit lonely from time to time.
1）a bit意为"有点儿"，表示程度，后面跟形容词、副词原级或比较级，相当于a little。
另外，a little可直接修饰名词，a bit后面加上of才可以修饰名词。
a bit of 后面加不可数名词，用法和a little一样。
例如∶ I'm a bit tired.
There is a little water.=There is a bit of water.
