used to的概念和用法
二、重点、难点
used to和be used to的区别
三、考情分析
used to是中考考查的重点知识，主要在单选、词汇运用、动词应用等题型中出现，分值在1-2分。
【教材原句】
He used to be so shy and quiet. 他过去是文静、内向的。
【概念】
used to是一个固定结构，它的意思是“过去经常、以前常常”，它的后面用动词原形，它表示过去存在某种状态或者过去的某种经常性、习惯性的行为或者动作，并意味着这种动作现在已经不存在，所以它只能用一般过去时，不能用现在时态。
【用法】
1. 它的陈述句的肯定形式：主语＋used to＋动词原形。
I used to play with my friends after school. 过去放学后我常常和朋友们一起玩。
2. 它的否定形式：主语＋didn’t＋use to＋动词原形。
You didn’t use to like pop songs. 你过去常常不喜欢流行歌曲。
3. 它的一般疑问句形式：Did＋主语＋use to＋动词原形＋其他？
Did your sister use to be quiet? 以前你的妹妹常常是很安静的吗？
4. used to的状语可以用副词always，often，sometimes等，但是仍然是过去的习惯，不是指现在的习惯，所以不能用一般现在时。
He always used to be late for class. 他过去常常上课迟到。
5. used to可以用在there be结构中表示“过去经常有”的意思。
There used to be a lot of fish in this river. 过去这条小河常常有许多鱼。
【拓展】
1. be used to （doing） sth.意为“习惯于（做）某事”，可用于各种时态，其中to为介词，used为形容词，to后可接名词、代词或动词-ing形式。
Are you used to the wet weather here? 你对这儿的潮湿天气习惯吗？
Mr. Li is used to washing his face with cold water. 李先生习惯于用冷水洗脸。
2. be used to do sth.意为“被用来做某事”，其中used为动词use的过去分词，to为不定式符号，应接动词原形。
This knife is used to cut bread. 这把刀子是用来切面包的。
【考题链接】
My father is used to _________early now.
A. get up
B. getting up
C. got up
D. gets up
答案：B
思路分析：be used to +v.-ing形式，意为“习惯于做某事”；be used to do sth.意为“被用来做某事”；由主语是my father，可知本句是主动语态，A项错误；句意为“我父亲现在习惯于早起床了”，故B项符合句意及语法点。
1. Usually computers ___________ to search the Internet.
A. use
B. are using
C. are used
D. used
2. My mother ________ us stories when we were children.
A. was used to tell
B. is used to telling
C. used to tell
D. used to telling
3. __________ used to_________ an old bookshelf in my room.
A. There; be
B. There; have
C. It; be
D. There; having
答案：1-3 CCA
思路分析：
1. usually通常是一般现在时态的标志词，D项是过去式，故错误；根据句意“电脑通常被用来上网”可知用被动语态，故排除A, B两项。
2. 从本句意思“我妈妈过去常常给我们讲故事，”可以理解为是用“used to＋动词原形”表示“过去常常”。
3. 本句是考查there be和used to连用的用法，表示“过去常常有”的意思。

There is a room in the building that is still free. There is a pretty girl who wants to see you. 7. 句子中如果已经有了who，引导词代替人，为了避免重复，要使用that；或者句子中如果已经有了which，引导词代替事物，为了避免重复，要使用that； 8. 先行词如果在主句中做表语，或引导词在从句中做表语，代替事物，多使用that；eg. 这是我昨天买的书。This is the book that I bought yesterday. as作为定语从句引导词的三点用法 （1）代替主句整句话内容； （2）先行词有such修饰，要使用as； eg. He is such a good teacher __as__ we all like. He is such a good teacher __that___ we all like him. (such…that 如此…以至于…,引导结果状语从句)； （3）先行词有the same修饰， the same……as表示同类不同一个：I want to buy the same bicycle as my friend did. the same……that表示同类同一个：The police has found the same bicycle that Jack lost. 引导词代替主句整句话内容，在从句中做主语或宾语，要使用as或which来引导 ?as和which的区别： 1.结构上as的从句既可以放于主句前，也可以放于主句后；which的从句只能放于 主句后； 2.as如果在从句中做主语，谓语动词只能是be动词结构； eg. 她数学考试不及格，这让她的爸爸很生气。

so-that的用法
so...that... 如此……以致于…… ...so that... 以便于，为了 “so...that...”句型的意思是“如此/这么……以致于……”，常引导结果状语从句，但“so...that...”是个爱“变脸”句型，你一不留意就会出错。“so...that...”句型及其转换也是中考的热点，现将其用法总结归纳如下，让我们一起来看看它是怎样变的吧。 一、 so... that...句型中的so是副词，常常用来修饰形容词或副词，常用句型为：主语+谓语+so+adj. / adv. + that从句。例如： 1. he is so young that she can't look after herself. 2. The boy ran so fast that I couldn't catch him. 3. He was so angry that he couldn't say a word. / 二、在“such... that...”句型中，such修饰名词，意思也是“如此……以致于……”但当名词前有many、much、(a) few、(a) little等词修饰时，句子中要用“so...that...”而不能用“such...that...”。例如： 1. He has so much money that he can buy what he wanted. 2. I've had so many falls that I have pains here and there. 3. There is little water in the glass that I can't drink any more. 三、 so与that也可连起来写，即变成：... so that ...(以便 / 为了……)，引导目的状语从句。例如： ~ 1. I got up early so that I could catch the early bus. 2. Please open the window so that we can breathe fresh air. 3. You must go now so that you won't be late. 四、以“so...that”引导的结果状语从句可以转换成不定式的简单句，即可转换为“...enough to...”或“...too...to”句型，但这种转换必须符合下列条件： 1. 当主句和从句的主语一致，且that从句是肯定句时，可用“enough to do sth.”来转换。例如：
语法中that的用法
“that”在英文中是一个使用频率很高的单词。它有四种词性，并且句法及语法功能纷繁复杂。同学们如果不能熟练掌握其用法，很可能会形成英语学习的一种障碍，从而影响其学习兴趣和效率。现将that的用法总结归纳如下： 第一、that 用作形容词（后接复数名词时用those）。 它用来指已被提到的人或物；也可表对比，指两个中较远的那个。 What about that book you borrowed from me last month？ 请注意，that 有时候在句子中具有喜欢或轻蔑等感情色彩。 that little son of his 他那个小宝贝儿子 That George！乔治那家伙！（含有轻蔑语气） 第二、that 用作代词。 1. that 用作指示代词（复数形式是those），其指代意义同形容词用法，同时它还可以用作定语从句中的先行词；还可为了避免重复，代替前述名词。That is what he told me. What is that (which) you have got in your hand? The price of rice is higher than that of flour. 2. that 用作关系代词，引导限制性定语从句。先行词可人可物，用法相当于who或which。（但是在下列情况下多用that：先行词既有人又有物时；先行词有形容词最高级、序数词、不定代词、very，only等修饰时；先行词是不定代词时） He talked about the teachers and schools that he had visited. I think it one of the most wonderful films that the film company has ever produced. She has little information that is useful for our research. Is there anything that I can do for you? 请注意，that 在定语从句中作宾语时通常可省略。The books (that) I sent you will help you in your studies. 第三、that 用作连词，引导名词性从句,状语从句和强调句。 1. that名词性从句。 ①引导宾语从句。及物动词后的引导词that可省略。I didn't expect (that) he could win the championship. The teacher pointed out that Tom was not working hard enough. ②引导主语从句。通常采用it作形式主语的句型。 That the earth goes around the sun is known to everyone. （It is known to everyone that the earth goes around the sun.） ③引导表语从句。 The trouble is that we are short of money. ④引导同位语从句。 引导同位语从句的that和引导定语从句的that是不同的。前者只起语法作用，在从句中不作任何成分；而后者在定语从句中作主语、宾语或表语。举例说明： The news that he resigned from office surprised us. The idea that he holds is very common nowadays on campus. 2. that引导状语从句①引导目的状语从句。 Bring it nearer that I may see it better. ②引导结果状语从句。What have I done that he should be so angry with me? ③引导原因状语从句。 I am afraid that I will fail in the driving test. ④引导让步状语从句。意为“虽然、尽管”。

考研语法小知识：that从句用法 一、that作连词引导各类从句 (一)that引导名词性从句 that后面连接一个完整的陈述句，可以位于主语、宾语、表语或同位语的位置，分别引导主语从句、宾语从句、表语从句和同位语从句。此时，that没有实意，而且不在从句中做任何成分。that引导主语从句和同位语从句时不可以省略。 例1：That the plates are movingis now beyond dispute.(主语从句) 地球板块是在漂移的，这一事实毋庸置疑。 例2：The truth isthat everyone should take care of orphan, not just the authorities.(表语从句) 事实是，所有人都应该照顾孤儿，而不仅仅是完全由政府承担。 例3：All people believedthat it was right to rescue the temple.(宾语从句)(注：that可以省略) 所有人都认为拯救古庙是正确的。 例4：The students expressed their hopethat they could be admitted by that university.(同位语从句) 学生们表达了他们向被这所大学录取的愿望。 (二)that引导定语从句 that引导定语从句，在从句中充当主语、表语或者宾语，既可以指代人，也可以指代物。that在定语从句中作宾语时，引导词that可以省略。 例1：The professor that you admire most will visit our university next month. 你敬仰的那个教授下月会到我们学校参观。 例2：This is one of the subways that will be put into use in two years. 这是未来两年内将开通的地铁之一。 例3：I have nothing that is worth reading. 我没有什么值得一读的东西。 (注：当先行词中有不定代词、形容词最高级、序数词或者先行词被the only，the very等限定词修饰等情况下 ，定语从句引导词也只能用that。) (三)that与其他单词结合引导状语从句 that可以和其他单词结构共同引导状语从句，例如such...that，so...that等引导结果状语从句，in order that，so that等引导目的状语从句，in that，now that，on the grounds that等引导原因状语从句 suppose/supposing/assume/assuming/provided/providing that，on condition that等引导条件状语从句等。 例1：She has madesuchrapid progressthatbefore long she could pass the exam. 她进步很快，不久就能通过考试的。 例2：You should make full use of this opportunityso thatyou can get rich experience. 你应该充分利用这次机会，以便获得丰富的经验。 例3：Supposing thatyou were in my position, what would you do? 如果你在我的位置，你会怎么做? 例4：On condition thatyou were lost in the desert, you should ask for help as soon as possible. 如果你在沙漠中迷路，你应该尽早寻求帮助。 (四)that引导强调句 “It is/was+被强调部分+that从句”是高频使用的一种强调句型，其中被强调部分可以作从句的主语、宾语和状语等。强调句中去掉“it is/was”和“that”后，句子成分和语义仍然完整。 例：It was after the war was over that Einstein was able to come back to his research work again. 战争结束后爱因斯坦才能重新进行他的研究工作。 二、that作限定词或代词 that可以作限定词或代词连接名词或名词短语，也可单独使用，用以指代人或者物。此外，that不仅可以指代单独的人或物，还可以指代一句话。 例：Furthermore, in the early days of long line fishing, a lot of fish were lost to sharks after they had been hooked. That is no longer a problem, because there are fewer sharks around now. [2006, text3] 分析：
初中it, one,that,those的用法
I. it／one ／that三者均可用作代词, 指代前面提到的名词。一般说来, it指代同名同物; one 与that则指代同名异物。 I have lost my umbrella; I'm looking for it. （该句中it就是指前面的my umbrella） I have lost my umbrella; I think I must buy one. （one在该句中表泛指, 因为my umbrella 已经丢了） The umbrella you bought is cheaper than that I bought. （替代词that在该句中特指“the umbrella I bought”, 以区别“the umbrella you bought”） II. one与that虽可用来指代同名异物, 但one为泛指, 相当于a／an＋名词; that为特指, 相当 于the ＋名词。所以one所指代的名词的修饰语一般为 a／an ／some ／any; that所指代的名词的修饰语往往是the ／this ／that。 A chair made of steel is stronger than one made of wood. （该句中one可以换成a chair） The water in the cup is hotter than that in the pot. （该句中that可以换成 the water） III. one只能代替可数名词单数, 代替可数名词复数时用ones; that既可以代替不可数名词也可以代替可数名词单数, 代替可数名词复数时用 those。 I like this pen more than that one. （one代替可数名词单数pen） There were a few young people and some older ones in the house. （ones代替可数名词复数people） Mary's handwriting is far better than that of Peter. （that代替不可数名词 handwriting） These pictures are more beautiful than those. （those代替可数名词复数 pictures） IV. one既可代替事物, 也可代替人, that只能代替事物而不能代替人。有时可以用the one或the ones代替that或those。 The one ／That on the table is mine. （该句中The one代替事物, 并且也可以用That） He is the teacher, the one who is loved by the students. （该句中the one代替人, 不能用that） He advised the farmers to choose the best seed-heads, the ones ／those that had the best color. （该句中the ones代替事物, 并且也可以用those） V. one一般有前置修饰语, 有时也可有后置修饰语或不用修饰语。而 that不能有前置修饰语, 但可有后置修饰语。 Cook was a strict but good captain, one who took good care of his sailors.
used to do的一些区别
used to do、be used to do与be used to doing sth.的用法详解used to do 过去常常做某事 be used to doing 习惯于做某事 be used to do sth 被用来做某事 1. used to的一般疑问句有两种构成方法： 1）将used提前至句首，结构为：Used + 主语+ to do sth...? 2）将did提前至句首，结构为：Did + 主语+ use to do sth...? 例如： Used he to get up early? = Did he use to get up early? 2. used to的反义疑问句有两种构成方法，例如： 1）He used to smoke，didn't he？ 2）They usedn't to like opera，did they？ 3.同样，其否定句也有两种构成方式： 1）直接在used后面加上not，也可一起缩写成usedn't. 结构为：主语+ used not to do sth... 或主语+ usedn't to do sth... 2）借助于助动词didn't，其结构为： 主语+ didn't use to do sth.... 例如： He used not to get up early. = He usedn't to get up early. = He didn't use to get up early. 4、be（get，become）used to结构在意义上相当于accustomed to“习惯于”，从形态上看，used是个分词型形容词，to是介词，因此后面只能跟名词、代词或动名词。例如： 1）They got used to living in the countryside．他们已习惯于住在农村。 2）I've got used to being a vegetarian．我已经习惯吃素食。 3）He is used to hard work．他习惯于艰苦工作。 5、be used to表示“习惯于某事”的状态，而get used to则表示由“不习惯”到“习惯于”这一动态的过程，意思是：“（变得）习惯于”；“开始习惯于”。试比较： He was used to the cold weather after he lived there for two years． 在那里住两年后，他已习惯了寒冷的天气。 I think it is a bit difficult for you to get used to the humid weather here． 我想，让你习惯于这里潮湿而炎热的天气有点困难。 You'll soon get used to living in the country． 很快你就会习惯于住在乡下了。 6、当主语是物的时候是指被用来做某事，be used to是动词use的被动语态，在这种结构里，to是不定式符号。例如： A metal bar was used to force the door open． 用金属棒把门撬开。
