教案 不定式
高考语法复习精讲非谓语动词之——不定式
时态主动被动否定
一般式To do To be done 在to 前加not
完成式To have done To have been done
进行式To be doing
完成进行式To have been doing
一，动词不定式的时态：
动词不定式用哪种形式要根据其动作与主句谓语动作发生的时间顺序来判断。
1 不定式的一般式：表示不定式的动作与谓语动词动作几乎同时发生，或在谓语动作之后发生，或者不强调不定式动作的时间性。但若是不定式表原因时，往往先于谓语动作之前发生。
如：
The news will not fail to surprise him.
I helped to repair the car.
☆注意：不定式表示谓语动作的原因时，往往发生在谓语动作之前。
如：
I am very happy to see you here.
She seemed surprised to meet us.
2 不定式的完成式：通常表示动作发生在谓语动词之前或者有与现在完成时连用的时间状语。如：
I am sorry not to have come to your party last night.
He seems to have finished his homework.
注意：若谓语动词是表示愿望，打算，意图的动词，如：hope, think, want, promise, plan, suppose, expect, mean, intend等时，不定式的用法如下：
A）上述动词的现在时+动词不定式的完成式，表示不定式发生在谓语动作之后，在将来发生。
如：I hope/expect/want/plan to have finished the task(任务) by the end of this month.
B)上述动词的过去时+不定式的完成式：表示本希望在过去发生的事情，但因故未能实现。
如：We planned to have finished the work before lunch.
3 不定式的进行式：表示不定式的动作正在进行，持续之中。可能在谓语动作发生时正在进行，也可能在谓语动作之后发生并进行。
如：
The boys were discovered to be hiding behind the door.
It's nice to be lying on the beach.
The boss doesn't like you to be always coming late for work.
4 不定式的完成进行式：表示不定式的动作在谓语动作之前就已开始，到谓语动作发生时可能停止，也可能继续下去。Tom seemed to have been reading a novel.
He is found to have been working for 4 hours.
二：不定式的语态
动词不定式除了有时态变化外，还有语态变化。用主动态还是被动态，取决于不定式和其逻辑主语的关系是主动还是被动。如果逻辑主语是动作的发出者，不定式用主动；反之，用被动。
1 不定式的主动主动语态：
如：
She came here to study, not to have a good time here.(目的状语)
She wanted me to buy some books.(me是to buy的逻辑主语，而不是she )
A mother must teach her children not to tell lies.
注意：不定式的逻辑主语可能是作者或说话人，用来表示说话人对所谈内容的看法或态度。
To begin with, she made a speech to the audience(观众)
To speak frankly, she doesn't work as hard as me.
To tell the truth, he is quite lazy.
这类表示态度的不定式固定搭配还有：
To be honest, 老实说
To cut a long story short长话短说，简而言之
To get (back) to the point回到正题
To put it another way换句话说
2 动词不定式的被动语态：
She asked the door to be closed.
She asked me to close the door.
I opened the door quietly in order not to _____________(disturb) him.(不定式作目的状语)
I closed the door quietly in order not to ______________(disturb) .(不定式作目的状语)
Have sth to do / have sth to be done 的区别：
Have sth to do 表示.....
Have sth to be done 表示.....
试比较：
I have some clothes to be washed today.我今天有些衣服要洗。（让别人帮忙洗）
I have some clothes to wash.(自己洗)
※不定式的主动形式表示被动※
A)在there be句型中，主语可用不定式修饰。如果句中主语是不定式的承受者，常常用不定式的主动表示被动。
如：There is still a lot of work to do.
B)too...to句型也常常用不定式主动代替被动。
如：The stone is too heavy to move.
和：The stone is too heavy for me to move.
C)在“主语+系动词+形容词+不定式”结构中，如果表语形容词说明的是主语的内在特征，往往用主动表被动。
形容词有:easy,difficult,hard,impossible,nice,pleasant,light,heavy,interesting,important,expensive,cheap, fit,dangerous等.
如：
The food is awful to eat
The problem is hard to solve
D)如果不定式后面跟的是“动词+介词”短语动词，介词不可省略。
You are pleasant to talk with.
The pen is hard to write with.
He is an impossible person to work with.
The problem is too difficult to work out
E)take作“花费”解时，其后的不定式总是用主动。
The book took me 2 years to write.
English takes time and energy to learn.学习英语需要花费时间和精力。
F)在"with+n+to do"结构中.
例如:
With nothing to do,he lay in bed.
With so many exercises to do,I can't go to the cinema.
G)一些作表语用的不定式的主动形式.
常见的这类动词有let(出租),rent,hire,blame等.
例如:
The house is to let.
I felt l was to blame.
三．不定式的句法功能：动词不定式在句中可充当主、宾、表、定、状、补。
1）作主语：
不定式作主语时，通常表示一个具体的，特定的行为。其谓语动词用第三人称单数形式。动词不定式作主语可位于句首。例如：
To live means to create.
To do that sort of thing is stupid.
To learn a skill is very important for everyone in society.
☆常用it作形式主语，而用动词不定式作实际主语的常用句型有：
1. It is＋adj (＋for sb.／sth.) ＋to do sth.表示“做某事对某人来说怎么样”。
此类形容词有：easy, hard, difficult, possible, important, impossible, necessary, good, bad, exciting, interesting, surprising等。例如：
It is interesting to play this game.
It is necessary for you to change your job.
2.It’s +adj.+of+sb.+不定式”表示“某人(做某事)怎么样”。通常表示根据事实判断人的品行，特征。
注意：这类形容词常描述主语的性格、品质的形容词（表语形容词），如good(好的)，kind(友善的)，nice(友好的)，polite(有礼貌的)，clever(聪明的)，foolish(愚蠢的)，lazy(懒惰的)，careful(细心的)，careless(粗心的)，wise(明智的)，right(正确的)，wrong(错误的)等。
It is very kind of you to help me (You are kind)
It is foolish of you to play fire at home (You are foolish)
3.It＋be＋名词＋不定式
用于此句型的名词有：pity, shame, pleasure, one’s duty, one’s job, fun, joy, good manners, bad manners等。例如：
It's our duty to take good care of the old.
It's a shame for you to do such kind of thing.
4. It takes sb.＋some time＋to do sth. 该句型意为“做某事花费某人多长时间”。例如：
It took us half an hour to ride to the town by bike.
2）作表语
动词不定式作表语常用于以下结构：
My wish/ job/ aim/ goal is to do或者The next step/ /important thing/problem/measure is to do等。
例如：
My wish is to be a teacher.
My goal is to pass the college entrance examination(高考，大学入学考试).
☆另外：不定式作表语常常用来表示预定要发生的动作，或表示未来的可能性或假设be to do 。
如：His greatest wish is to see an end to the war.
注意：当主语中含有实义动词do的各种形式时，作表语的不定式通常省略“to”.
All you have to do is (to) finish the job as quickly as possibly.
All I can do is just smile at him and say nothing.
3）作宾语
许多动词都可和不定式搭配，即这些动词的用法决定了其后接带to的不定式作宾语。有些动词只能接“疑问词+不定式”作宾语。而句中的主语常常就是不定式的逻辑主语。
常见的只能使用动词不定式作宾语的动词有：
agree, choose, decide, hope, fail, wish, refuse, expect, manage, plan, intend, pretend, promise, offer, afford, demand, arrange等如：
They decided to build a highway between these two cities.
She offered to help me when I was in trouble.
He promised not to tell anyone about it.
常接“疑问词+不定式”作宾语的动词有：
decide,discover,forget,inquire（询问），know,learn,remember,see,settle,think,wonder.
例如：
I don't decide/know what to do/where to go.
I can't remember what to do.
I forgot how to operate the machine.
注意：当作宾语的不定式是较长的短语，常常用it作形式宾语，而把真正的不定式放到句末去。
常常这样用的动词有believe, think, consider, find,feel, make等动词。
可构成句型“动词+ it +adj. / n+to do sth.”句型，其中使用it作形式宾语，而将真正的宾语动词不定式置于句末。
例如：
I think it necessary for us to have a good rest after the long work.
the teacher made it a rule to practise oral English every morning
4）作介词宾语
以下介词之后常用省to的不定式作宾语。（前面有do，后面省to）
这类介词主要有：Than ,But ,Except除。。。之外
Have nothing to do but do
Have no choice but to do
如：
I couldn't do anything but wait here.
The enemy(敌人)had no other choice but/than to surrender(投降).
在下列短语后，but之后只能跟省to的不定式。
Do nothing but 只能Cannot but禁不住。。。
Do anything but决不Cannot choose but只得。。。
Cannot help but不得不
如：
She couldn't help but laugh at his clothes.她情不自禁地大笑他的着装。
I cannot but admire(钦佩) his courage.
I could not choose but love her.我不禁爱上了她。
5）作宾补
不定式作宾补时，其逻辑主语常常就是它前面的宾语。
1)可后接动词不定式作宾补的动词有：advise, allow, ask, beg, cause, challenge(挑战), convince(使信服), dare, drive(驱使), encourage, expect, forbid, force(强迫), hire, instruct(指导), invite, need, order, permit(允许), persuade, require, teach, tell, urge, hear, order, see, want, wish, worn(警告)等。
例如：
The doctor advised her not to eat too much sugar.
I wish you to go to the meeting with me. Wish sb to do / hope to do
I persuaded him to give up smoking.
2)注意：有一类表示见解，看法的动词，如：believe, consider, count, declare, deny, feel, find, guess, imagine, judge, know, prove, realize, suppose, think等动词后常常接to be型不定式作宾补。to be可以省略。例如：
He declared himself （to be）a college student. 他自称是名大学生。
The police proved him （to be ）a thief. 警察局证实他是小偷。
We consider him (to be ) diligent(勤奋的).
☆特别注意hope, demand, suggest等动词不能后接动词不定式作宾补。例如：
判断正误：（T or F )
I hope my son to be back soon.
I hope my son will be back soon.
She suggests us to have a discussion about it.
She advises us to have a discussion about it.
She suggests that we (should) have a discussion about it.
3)在主动结构中，下列动词后作宾补的动词不定式应省略to：。例如：
“一感”(feel)
“两听”(hear, listen to)
“三使”(make, let, have)
“五看”(see, watch, notice, observe, look at)
His boss made/have/let him work all day long.
I heard him sing in her bedroom.
I saw him play basketball on the playground.
但是，改为被动结构后，应该还原省略的to。例如：
He was seen to break the window.
4)表示好恶的动词+宾语+带to的不定式
这类动词主要有：
Dislike不喜欢Like喜欢Prefer更喜欢
Hate讨厌，不喜欢Love喜爱Want想要
如：I like people to tell the truth.
She preferred me to do my job by myself.
I hate him to speak loudly in the classroom.
6）作定语
动词不定式作定语，应位于所修饰词语之后，即：作后置定语。
被修饰的名词和用作定语的不定式之间有三种关系：
1逻辑主谓关系
由only, first, last, next, only, second以及序数词或形容词最高级修饰的名词后，也常接不定式作定语。例如：Who was the last one to leave the classroom last night?
She was the first girl to come to the party.
2 逻辑宾语的关系。例如：
1）当谓语动词是be, find, get, give, have, need, want等，它们后面的名词（宾语或者表语）常常用不定式修饰。如：
Have you got anything to eat? (to eat修饰anything，位于其后)
Do you have anything to say/declare(宣布)？
What I want is to get something to do.
2）当不定式的动词是vi或不能构成动宾关系时，要加相应的介词。
We found a house to live in.
This is the only point for us to pay attention to.
用相应的介词填空：
I need/want a piece of paper to write ______.
There are a lot of goods(商品)to choose __________
Mike is the person for me to turn _______ in difficult time.
My boss is the man easy to get along _________
3）无关系（常放在一类名词后）
此类名词：ability, attempt, chance, courage, decision, effort, evidence, failure, means, measure, reason, refusal, promise, right,way, wish等。例如：
But she gave up the chance to go abroad.
You have no right to speak.
He has the ability to work out the math question.
I have the courage to invite her for dinner.
She has a great wish to to travel around the world.
7）作状语
动词不定式作状语，可表示目的、原因、结果、条件、方式等。
1 作目的状语：不定式的动作稍晚于谓语动词的动作。
如：I must leave now to get there on time.我必须马上动身，以便按时到达那儿。
I am saying this to encourage you.
I store the food in the fridge to keep it fresh.
We went there to see our grandparents.
※in order to do / so as to do / to do 的用法：
A)不定式表示目的时，其逻辑主语常是句子的主语。如：
Many people go to work on foot in order to /so as to lose weight.
He worked so hard so as to get high salary(薪水).
例题：In order to make the city green ,_____________ .
A many trees were planted
B the government planted many trees
C we planted many trees
B)in order to 和so as to 的否定式是在to前面加not，构成in order not to 和so as not to.
He studied in his bedroom so as not be disturbed.
I got up so early in order not to miss the early bus.
C)in order to/ to do既可以放在句首表目的，亦可以放在句中，而so as to 只能放在句中。
In order to catch the early bus, I get up early every day.
=I get up early every day so as to catch the early bus.
D) in order to do => in order that ...
So as to do => so that ....
I got up early in order to catch the first bus . => I got up early in order that I could catch the first bus .
2 不定式作结果状语时，总是出现在被修饰的动词之后，并且常用以下结构：
结构中文含义
So+形容词/副词+as to do 如此。。。以致
Such+（形容词+）名词+as to do 如此。。。以致
Enough+名词+to do 足够。。。
名词/形容词/副词+ enough+to do 足够。。。
Too+形容词/副词+to do 太。。。以致不能。。。
如：
What have I said to make you so angry?
What have I done to offend you?
They said goodbye, never to meet again.
用so...as...和such...as...引导的结果状语：
He is not so stupid as to do that.他还没用蠢到去做那种事情。
He got up so early as to catch the first bus.
他起的如此早，以致他赶上了头班车。
She is such a beautiful girl as to be liked by people.
He is such a strong boy as to carry that heavy box.
由too...to...引导的结果状语，意为“太。。。以致不能。。。”
注意：
1 只能用不定式的肯定形式
2 如果不定式的动词是vi ，则需加相应的介词
3 不定式与所修饰词之间构成逻辑动宾关系
The food is too hot to eat.
I am too tired to study any more.
改错：
The box is very heavy to be carried .
The room is comfortable to live .
注意：
A)如果too 前有all,but,not,only等修饰时，too的意思是“非常、很”，这种情况下，即使too后面跟了不定式，也不含否定意义，不表示结果。
I am not too sad to see them leave.
I am not too happy to meet you.
I am only too pleased to help you.
B)当too和以下形容词连用时，即使其后跟有不定式，也不表示否定，too意为“非常。”
这些形容词有：
Pleased高兴的Glad高兴的Apt易于。。。
Anxious焦急的Willing愿意的Ready愿意的
Eager渴望的Kind好心的Inclined倾向于。。。
如：
I am too glad to see you.
Food is too apt to go bad in summer.
She is too eager to see you.
由enough引导的结果状语。
注意：enough用来修饰名词时，可以放在名词前面或后面；但是用来修饰形容词或副词时，只能放在其后。
如：He made enough noise/noise enough to wake the dead.
He was kind enough to help me.
☆另外：only to do 作结果状语，暗示一种意外的结果。
如：
He worked hard only to fail in the exam.
He rushed to the station only to find the train had left.
He invited the girl for dance only to receive a polite refusal.
3 动词不定式用作原因状语，通常放在谓语之后，表示原因。该状语的时间常常略早于谓语动作发生的时间。如：
They jumped high to hear the news.
I feel very happy to be praised by my teacher.
I am very sorry to hear that.（原因）
The boy was shocked to see his girlfriend walk hand in hand with another boy.
4 动词不定式用作条件状语。此时，不定式位于句首，句末皆可。
如：She will be glad to hear the news.
He would be stupid not accept her advice.
To look at him, you could not help laughing.
5 不定式用作方式状语。此时，不定式前面常常有as if，as though，表示比喻关系。
如：He raised his hand as if to stop the car.
She opened her mouth as though to speak.
初中英语语法精讲动词不定式用法(教案)
动词不定式用法 动词不定式没有人称和数的变化，在句中不能独立作谓语。但动词不定式具有名词、形容词和副词特征，在句中可以作主语、宾语、宾语补足语、定语、表语和状语等多种成分。另外，动词不定式具有动词特点，可以有自己的宾语和状语，组成动词不定式短语。动词不定式的肯定形式是to＋do；其否定形式是not to＋do。 下面以动词不定式在句中的作用来予以详细说明。 1．作主语 可以直接作主语。如：To see is to believe． 但在英语中，常用it作形式主语，真正的主语即动词不定式放在后面。如： It's wrong to play tricks on other people． It's our duty to keep our environment clean and tidy． 点击规律：动词不定式在句中作主语时，常放在It is ＋adj +(for sb.)＋(not)to do sth句型中，表示说话人对客观事件的决断，意为：做…..是……的，it仅作形式主语，真正的主语是to do sth It is very interesting to read.读书是有趣的 It is useful to read.看书是有用的 It is healthy to run every day.每天跑步是健康的 It is a little difficulty for me to work out this question.解出这道题对我来说有点难 It is bad not to finish homework.不完成作业是糟糕的 It is bad to be late for school.迟到是糟糕的 It is+adj+of sb +(not)to do sth该句型通常表示说话人对客观事件的惊讶、兴奋、懊悔、难过等感叹情绪，与It is ＋adj +(for sb.)＋(not)to do sth的意义不同。 It is very kind of you to tell me the truth．你能告诉我事实，真是太好了 It is stupid of him to do such a silly thing．他做那件傻事，真是太笨了 It is very clever of you to work out this question. 你能解出这道题目，真是太聪明了 It is very wise of you to read this novel. 你看这本小说，真是太明智了 这个句型中用介词of而不是for的原因是这里的形容词是用来形容人的品质性格的。 类似的词有：careless，careful，clever，considerate，foolish，good，impolite，kind，naughty，nice，silly，stupid，friendly 因此区分是用It is ＋adj +(for sb.)＋(not)to do sth还是It is+adj+of sb +(not)to do sth，要

不带to的动词不定式讲课教案
不带to的动词不定式有哪些 不定式是英语动词的非限定形式之一，是英语中一种非常活跃的语言现象，不带to的不定式（bare infinitive）是我们学习、掌握和运用这一语法现象的难点。本文的目的就是要对不带to的不定式作一粗浅的探讨。首先要指出的是，不带to的不定式的使用实际上非常普遍，主要用在情态动词和助动词will，shall，would，should，can，could，may，might，must…以及在作为情态动词的need和dare之后。但因为这一点在学习英语的过程中极易掌握，故不在此赘述。除此以外，在下列情况下也要使用不带to的动词不定式。 1．在see，feel，hear，watch，observe，listen to，look at, notice等感官动词或短语以及let，have，make等表示祈使意义的动词后面；不定式作宾语补足语不能带to；help后面的不定式可以不带to，也可以保留to；know在一定的条件下，后面的不定式作宾语补足语时可以不带to。例如： I saw the man come out of the house． I heard her say that she was from Japan． We felt the house shake． They watched the sun sink into the sea． Did you notice him stop？ They did not observe Jim come in and go upstairs． She was listening to him climb the stairs． Look at the boy run！ I'll let you know as soon as I hear from her． I had him mend my watch． Electricity makes motors run． He helped me（to）plant trees． I have never known him sing so beautifully． 不带to的动词不定式跟在上述动词后面时，情况比较复杂，有以下几个问题须特别注意： （1）当上述句子变成被动语态时，原来作宾语补足语的不定式则相应地成为主语补足语。这时，不定式就一定要带to，以上述句子为例：

动词不定式教案 教学目标 1.学会什么是动词不定式 2.会使用动词不定式 重难点 1.能正确的使用动词不定式的各种用法 教学步骤 Grammar: 动词不定式 Ⅰ. 不定式句法功能 1. 作主语：The cat said, “To take roller coaster” is terrible. 不定式短语作主语时，可以直接放在句首，但在很多情况下，尤其是在疑问句和感叹句中，往往放在谓语之后，而用先行代词it作形式主语。 → The cat said, “It’s terrible to take roller coaster.” How long did it take you to take roller coaster? How terrible it is to take roller coaster? 不定式作主语常见句型： a) It is + adj. (easy, important, difficult…) + 不定式 b) It is + n. (a pity, a pleasure, one’s duty, a shame) + 不定式 eg. It’s my dut y to teach you how to be a student of No.3 Middle School. c) It takes/needs/requires + some time (hours, months, days, patience…) + 不定式 eg. It requires patience to be a good teacher. 2. 作表语：当句子的主语是aim, idea, policy, question, suggestion, wish, task, duty, job, purpose等或者主语是what引导的名词性从句时，后面可以用不定式做表语，用以说明主 语所包含内容。 eg. Our most important task now is to make a plan. 注：作表语的不定式都带to，但当主语部分有实义动词do时，to可以省略。 eg. The only thing we can do now is wait and see. 3.作宾语 The cat said “Remember not to take it next time!”. a) 可以直接用不定式作宾语的动词很多，常见的有：agree, afford, tend, ask, decide, determine, expect, fail, hope, learn, intend, manage, offer, plan, promise, refuse, want, wish等 I don’t want _____ like I’m speaking ill of anybody, but the manager’s plan is unfair.

We have no choice but to wait. Cf. We can do nothing but wait.

动词不定式教案(原创)
首先，介绍课堂大致结构，分为六个部分：一、定义 二、动词不定式的主要构成 三、动词不定式的用法 四、动词不定式的否定形式 五、动词不定式的其它用法 其次，细讲每个部分； 最后，总结回顾，强调本节课重难点。 重难点：1. 对动词不定式作主语时,常用it 作形式主语时的转化； 2. 动词不定式作定语时，对于哪些动词要加相应的介词，以及区分及物动词&不及物动词的方法； 3. 掌握动词不定式的常见用法，尤其其中一些特殊的不带to 的不定式用法。 一、动词不定式的定义： 动词不定式是一种非谓语动词。 注：非谓语动词，即不能作谓语，且没有人称和数的变化的动词。 二、主要构成：to + 动词原形（被动形式：to be +过去分词） 注：to 只是不定式符号，没有实际意义，当然它也存在不带to 的情况。 三、动词不定式的用法： 注：动词不定式有动词的性质，可接宾语和状语构成不定式短语，作主语、表语、宾语、定语、状语、补语。 1.作主语： E.g. To answer your questions is difficult. (不定式作主语的时候，谓语动词用单数。) （但显然，句子从形式上来看，显得头重脚轻，所以通常我们会把它写成以it 作形式主语的形式，见下例：） ***It is difficult to answer your questions. (回答你的问题很难。) Note: 形式主语："it" 真正主语："to answer your questions" 2.作表语： E.g. a. The most important thing is to save the boy first. (最重要的事情是先救那个男孩。) “Is+ 不定式”为系表结构，故不定式在这里作表语。 b. My wish is to be a doctor. 3.作宾语： 动词不定式作及物动词的宾语，常见的及物动词有： begin/ start, want, hope, forger/ remember, love/ like, need, try, learn, wish, agree, choose, plan, decide, refuse等 E.g. a. I want to ask you a question. Note: "to ask you a question"为"want"的宾语。 b. I plan to go shopping this weekend. 4.作定语： 比较句子a&b:

非谓语动词之三——动词不定式 一、不定式的作用 1、作主语 不定式作主语时，谓语用单数。往往用it 作形式主语，把不定式放在谓语后面。如： It took us two hours to finish the job. It is impossible for us to get there on time. It is very kind of you to help us. 注意：（1）其他系动词如look, appear等也可用于此句型。 （2）当不定式作主语的句子中又有一个不定式作表语时，不能用 It is …to…的句型。试比较： It is to negate my own idea to believe him. To believe him is to negate my own idea . （3）It is+ adj. of / for sb. to do sth. 结构中，当不定式的逻辑主语和前面的形容词可以构成系表结构时，用of, 否则用 for. 2、作宾语 （1）动词+不定式。如： He managed to escape from the fire. I find it hard to get along with him.（it 作形式宾语） 注：下列动词通常用不定式作宾语：want, try, hope, wish, need, forget, know, promise, refuse, help, decide, begin, start, learn, agree, choose, get等 （2）动词+疑问词+to , “特殊疑问句+不定式”相当于名词，作宾语。如： I don’t know what to do next/ how to do it next. I can’t decide when to go there. 注意：不定式短语作宾语时，如果还带有宾语补足语，往往把不定式短语放在宾语补足语之后，用it 作形式宾语。如： I find it necessary to learn a foreign language. 3、作宾语补足语 （1）动词+宾语+不定式（to do ）。如： He warned me to be careful. I want you to speak to Tom. What makes you think so?（不带to的不定式） 注：可以用动词不定式做宾补的动词有：ask, tell, order ,want ,get, would like, like, advise, invite, allow, help, wish,warn, expect, prefer, encourage （2）表见解、看法的动词结构可为：动词+宾语+ to be 的不定式结构。如：We consider Tom to be one of the best students in our class.
