Ⅳ.阅读理解
Americans are proud of their variety and individuality，yet they love and respect few things more than a uniform，whether it is the uniform of an elevator operator or the uniform of a five-star general.Why are uniforms so popular in the United States?
Among the arguments for uniforms，one of the first is that in the eyes of most people they look more professional than civilian(百姓的) clothes.People have become conditioned to expect superior quality from a man who wears a uniform.The television repairman who wears uniform tends to inspire more trust than one who appears in civilian clothes.Faith in the skill of a garage mechanic is increased by a uniform.What easier way is there for a nurse，a policeman，a barber，or a waiter to lose professional identity(身份) than to step out of uniform?
Uniforms also have many practical benefits.They save on other clothes.They save on laundry bills.They are tax-deductible(可减税的)．They are often more comfortable and more durable than civilian clothes.
Primary among the arguments against uniforms is their lack of variety and the consequent loss of individuality experienced by people who must wear them.Though there are many types of uniforms，the wearer of any particular type is generally stuck with it，without change，until retirement.When people look alike，they tend to think，speak，and act similarly，on the job at least.
Uniforms also give rise to some practical problems.Though they are long-lasting，often their initial expense is greater than the cost of civilian clothes.Some uniforms are also expensive to maintain，requiring professional dry cleaning rather than the home laundering possible with many types of civilian clothes.
1．It is surprising that Americans who worship variety and individuality ________.
A．still judge a man by his clothes
B．hold the uniform in such high regard
C．enjoy having a professional identity
D．will respect an elevator operator as much as a general in uniform
2．People are accustomed to thinking that a man in uniform ________.
A．suggests quality work
B．discards his social identity
C．appears to be more practical
D．looks superior to a person in civilian clothes
3．The chief function of a uniform is to ________.
A．provide practical benefits to the wearer
B．make the wearer catch the public eye
C．inspire the wearer’s confidence in himself
D．provide the wearer with a professional
4．According to the passage，people wearing uniforms ______.
A．are usually helpful
B．have little or no individual freedom
C．tend to lose their individuality
D．enjoy greater popularity
5．The best title for this passage would be ________.
A．Uniforms and Society
B．The Importance of Wearing a Uniform
C．Practical Benefits of Wearing a Uniform
D．Advantages and Disadvantages of Uniforms
immediately ad v.立即；马上
生义：conj.一……就

Ⅱ.1.我19岁，曾经是一个吸毒上瘾的人。

2．B[be addicted to对……上瘾。]
3．A[in danger处于危险中；share sth.with sb.和某人分享某物。]
4．C[take带走，符合句意。bring带来；carry强调随身携带；fetch强调动作往返。] 5．C[动名词或不定式可作句子的主语，动词原形、过去时，一般现在时的第三人称单
数都不能作句子主语。]
6．B[allow后接复合宾语加带to的不定式。]

9．D[stop doing sth.停止做某事，符合句意。stop to do sth.停下来做某事。]
10．B[dangerous危险的，符合句意。in danger指人或动物处于危险之中；out of danger 指人或动物脱离危险。]
Ⅳ.1.B[细节理解题。第一段第一句yet转折后面就是答案。hold...in regard和respect 是同义转换。]
2．A[推理判断题。答案对应在第二段第二句中的“People ... expect superior quality...”认为穿制服的水平更高。D项错在混淆了superior的目标，不是人，而是quality，所以不对。] 3．D[细节理解题。在第二段末尾，道出了制服的主要功能是什么。A项是实际的好处，而不是主要功能。]
4．C[细节理解题。在第四段。制服的一个主要缺点。]
5．D[主旨大意题。文章的主题是讨论了制服的优缺点。]

I like Jack as much as she.＝I like Jack and she likes him，too. (2)两个以上的人称代词并列，其次序排列原则： 在并列主语中，“I”总是放在最后，排列顺序为：二三一(人称)。宾格me也一样。 You，she and I will be in charge of the case. Mr.Zhang asked Li Hua and me to help him. 2．物主代词 (1)注意名词性和形容词性物主代词各自的语法功能。 (2)one’s own...＝...of one’s own句式的转换。 (3)某些固定结构中常用定冠词代替物主代词。 take sb.by the arm，be wounded in the leg 3．反身代词 (1)反身代词的语法功能：宾语、表语、主语或宾语的同位语。 (2)反身代词和某些动词连用，构成固定短语。 devote oneself to致力于 重点单词 1.fit adj.合适的；健康的;能胜任的;v.适 合，合身；使胜任 I’m quite .我很健康。(回归课本P1) 观察思考 He keeps fit with diet and exercise. 他通过节食和运动来保持健康。 That kind of music fits your mood. 那种类型的音乐适合你的心情。 This coat fits you perfectly but the trousers are too large. 这件外套你穿着很合适，但是裤子太大了。 She is not fit to look after children. 她不适合照看小孩。 归纳拓展 be fit for适合；胜任be fit to do适合干…… It is fit for sb. to do/that...某人做……是合适的 keep/stay fit保持健康 fit one’s deeds/actions to one’s words做到言行一致fit in安排时间见(某人);安排时间做某事；相处融洽;适应 fit on装上；试穿 fit out装备，配备；给……提供必要的东西 易混辨异 match/suit/fit 这三个词都可表示“适合，配得上”，但用法上 仍有差别。 (1)match指两者的“相配；配得上”,指人或物 在品质、颜色、设计等方面相当或相配。 (2)suit常用于指“适合;恰当”,多指符合需要、口味、性格、条件等。尤其用来指衣着的式样、颜色或发式与人相配。 (3)fit多用来指大小、形状、位置等适合及服装合身。活学活用——用fit,suit,match的适当形式填空 (1)These shoes me perfectly. (2)The doors were painted blue to the walls. (3)The climate the old man well. (4)The patient girl is for teaching. (5)No one can him because he is a leading professor in the field of physics. (6)Will Thursday or Wednesday you? 2.anxious adj.焦虑的；渴望的；不安的 Helen is anxious about travelling on her own. 海伦对自己一个人出门旅行感到担心。 She was anxious to finish school and get a job. 她渴望毕业找到一份工作。 The mother waited for her son with anxiety. 母亲焦虑地等着儿子。 归纳拓展 anxiously adv.焦急地;担忧地anxiety n.忧虑;渴望 be anxious about担心，忧虑 be anxious for...渴望得到…… be anxious (for sb.) to do sth.渴望(某人)做某事 be anxious that...担心……(that从句中用虚拟语气) be in anxiety非常担忧with anxiety焦虑地 too anxious to do sth.非常渴望做某事 eager/anxious (1)eager指以巨大的热情渴望实现或达到目的,含有积 极向上的意义,有时也指由于其他感情而表现得急不可耐。 He is eager to do that interesting job. 他急于做那份有趣的工作。(有积极的干劲和热情) (2)anxious指热切地希望实现愿望,并因顾虑愿望落空 而心情不安,感到焦虑,强调“担心”和“焦虑”,对结果感到不安。 I’m anxious to know the final result. 我急切地想知道最后的结果。(心中焦急) 活学活用 (1)—I wonder if she will show up at the concert. —She will.She is only too to watch the famous conductor. A.anxious B.proud C.interested D.satisfied 解析由句意可知，此处指“她很渴望看到 那位著名的指挥家”，故用anxious。B、C 两项不合题意；D项无此搭配。 (2)My mother always gets a little if we don’t arrive when we say we will. A.anxious B.ashamed C.weak D.patient 解析句意为：当我们说将要到而没到时，母 亲总是有点担心。 3.pain n.疼痛;痛苦;辛苦,努力(用复数);vt.使痛苦；vi.感 到疼痛 观察思考 His broken leg gave him a lot of pain. 他的断腿使他非常疼痛。 She suffers greatly from a pain in the back. 她的背痛得很厉害。 No pains,no gains.(谚语)不劳无获。 We are pained to see such wastefulness. 我们看到这种浪费现象很痛心。 归纳拓展 1 2014-2015学年高中英语同步（步步高）练习（1）及答案：Module 2 No Drugs（外研版必修2） Module 2 No Drugs Period One Reading Comprehension Ⅰ.用适当的介、副词填空 1．I bought cannabis from a man ________ the street. 2．Users who inject the drug are also ________ more danger if they share needles ________ other users. 3．Crack cocaine is the most addictive form ________ cocaine. 4．Users become addicted ________ crack cocaine much more easily if they smoke it. 5．When I went ________ to the man again，I wanted more crack cocaine. 6．But he asked me ________ a lot of money. 7．I didn’t have enough money ________ he didn’t give me any drugs. 8．I was ________ terrible pain. 9．The next day，I broke ________ a house and stole a television and a video recorder. 10．________ a result，cocaine users sometimes have heart attacks.

My new school is very good and I can see why. The teachers are very enthusiastic and friendly and the classrooms are amazing.Every room has a computer with a special screen, almost as big as a cinema screen. The teachers write on the computer, and their words appear on the screen behind them. The screens also show photographs, text and information from websites.They’re brilliant! The English class is really interesting. The teacher is a very enthusiastic woman called Ms Shen.We’re using a new textbook and Ms Shen’s method of teaching is nothing like the teachers at my Junior High school. She thinks that reading comprehension is important, but we speak a lot in class, too. And we have fun.I don’t think I will be bored in Ms Shen’s class! Today we introduced ourselves to each other.We did this in groups.Some students were embarrassed at first but everyone was very friendly and it was really nice. Ms Shen gave us instructions and then we worked by ourselves.Ms Shen wants to help us improve our spelling and handwriting. We do this in a fun way, with spelling games and Module 1 Our body and Healthy Habits Introduction Look at these words and expressions. Which of them are connected with illness? dentist diet fat fit flu (influenza) get/catch a cold health rare toothache unhealthy wealthy Read the proverbs and try to explain them in English. ?You are what you eat. % ?Healthy mind in a healthy body. % ?Early to bed, early to rise makes a man healthy, wealthy and wise. % ?An apple a day keeps the doctor away. % Vocabulary and Reading 1.Look at these words and answer the questions. anxious; break (as in break an arm); captain; fever; injure; injury; pain; painful; normal; sweets 1. Which word is connected with food? 2. Which words are connected with body? 3. Which word means usual or ordinary? 4. Which word means leader? 5. Which word means worried about something that may happen? Zhou Kai (1) When Zhou Kai's mother saw him heading towards the front door without a jacket on, she eyed him anxiously. "Zhou Kai, where are you going?" she asked. "To the park. I'm going to play football," said Zhou Kai. "But it's raining! You'll catch a bad cold," said his mother. "No, I won't. I'll be fine," said Zhou Kai, as he opened the door. "Zhou Kai, you'll get ill. You know you will. You can at least go and get your jacket." "OK, OK." Zhou Kai went and did as he was told.【2020年】2020年外研版高中英语必修一(全册)精品教案汇总
