题型组合加餐练Ⅰ.阅读理解AWhat if there was a fire where you live？Would you know what to do？It’s a good idea for families to talk about what they would do to escape from a fire.Depending on where you live，there may be different escape plans，so let’s start there.Know Your Way OutAn escape plan can help every member of a family get out of a burning house.The idea is to get outside quickly and safely.Smoke from a fire can make it hard to see where things are，so it’s important to learn and remember the different ways out of your home.How many exits are there？How do you get to them from your room？It’s a good idea to have your family draw a map of the escape plan.It’s possible that one way out could be blocked by fire or smoke，so you had better know where other ones are.Safety StepsIf you’re in a room with the door closed when the fire breaks out，you need to take a few extra steps：·Check to see if there’s heat or smoke coming in the cracks around the door.·If you see smoke coming under the door，don’t open the door!·If you don’t see smoke，touch the door.If the door is hot or very warm，don’t open it!·If the door feels cool，and you can’t see any smoke around the door，you can open the door very carefully and slowly.If there’s still no smoke or heat when you open the door，go toward your escape route exit.语篇解读本文是一篇说明文，介绍了火灾发生时的逃生计划。

高一英语必修第一册(2019版)_Unit4_单元测评
Unit4 单元测评第一部分听力（共两节，满分30分）略第二部分阅读理解（共两节，满分35分）第一节（共10小题；每小题2.5分，满分25分）阅读下列短文，从每题所给的四个选项（A、B、C和D）中选出最佳选项。
（2020·北京四中高一月考）Getting less sleep has become a bad habit for most American kids. According to a new survey by the National Sleep Foundation, 51% of kids aged 10 to 18 go to bed at 10 p.m. or later on school nights, even though they have to get up early. Last year the Foundation reported that nearly 60% of 7-to 12-year-olds said they felt tired during the day, and 15% said they had fallen asleep at school.How much sleep you need depends a lot on your age. Babies need a lot of rest: most of them sleep about 18 hours a day! Adults need about eight hours. For most school-age children, ten hours is ideal. But the new National Sleep Foundation survey found that 35% of 10-to 12-year-olds get only seven or eight hours. And guess what almost half of the surveyed kids said they do before bedtime? Watch TV.“More children are going to bed with TVs on, and there are more opportunities(机会) to stay awake, with more homework, the Internet and the phone.” says Dr Mary Carskadon, a sleep researcher at Brown University. She says these activities at bedtime can get kids all excited and make it hard for them to calm down and sleep. Other experts say part of the problem is chemical. Changing the levels of body chemicals called hormones not only makes teenagers’ bodies develop adult characteristics, but also makes it hard for teenagers to fall asleep before 11 p. m.Because sleepiness is such a problem for teenagers, some school districts have decided to start high school classes later than they used to. Three years ago, schools in Edina, Minnesota, changed the start time from 7:25 a. m. to 8: 30 a.m.Students, parents and teachers are pleased with the results.21.What is the new National Sleep Foundation survey on?A. Learning and sleeping problems.B. Teenagers sleep-related diseases.C. Activities to prevent sleeplessness .D. American kids’ sleeping habits.22.How many hours of sleep do 11-year-olds need every day?A. 7 hours.B. 10 hours.C. 8 hours.D. 18 hours.23.Why do teenagers go to sleep late according to Carskadon?A. They are affected by certain body chemicals.B. They tend to do things that excite them.C. They follow their parents’ examples.D. They don’t need to go to school early.B（2020·衡水中学期中）Snowbirds are people who leave their homes when the temperature drops and head to warmer climates. They are mostly retirees and business owners who can afford to take the winter off. While the snow flies in the Northern states, they are enjoying golf, sailing and barbecues in mild temperatures in the South. Then, after winter passes, they return to their homes in the North.Most snowbirds are away from Canada and the Northern states between the middle of October and the end of November. They pack up and head to Florida, Alabama, Texas, California, and all of the other Southern states. Some may even go as far as Australia or Italy to escape the cold winter weather. There are special communities for snowbirds in many areas. Snowbirds are also offered special discounts in some restaurants, hotels and area attractions. Several states even have special snowbird resorts（度假胜地）.There are several online communities and local resources to help snowbirds get set in their seasonal homes.Some snowbirds own homes both in the South and in the North. Both homes have everything they will need for their stay, minimizing the amount of packing necessary when moving from one to the other. Other snowbirds will rent apartments for theduration of their stay outside of their home state.Recreational vehicles, or RVs（房车），are a huge part of the snowbird lifestyle. RVs allow snowbirds to move from place to place on a whim（奇想），bringing everything they need with them. They spend nights in RV parks, large parking lots or anywhere else they choose to stay. RVs have beds, bathrooms, and most other modern conveniences available in a regular home. Although the spaces are small, there is more than enough room for a couple to live in.24.Which of the following can be regarded as a snowbird?A. One who retires and has a lot of free time.B. One who likes to play in snow in winter.C. One who travels around the world the whole year.D. One who heads for the South to avoid the cold weather.25.We can infer from Paragraph 2 that ________.A. the Internet makes it easier for snowbirds to find seasonal homesB. snowbirds are not welcome in many areasC. snowbirds have to stay in special communitiesD. it doesn’t cost much to be a snowbird26.Recreational vehicles allow snowbirds to ________.A. avoid the heavy trafficB. carry everything they have at homeC. have a comfortable life wherever they areD. save more money than renting an apartment27.We can conclude from the passage that ________.A. one has to be quite wealthy to be a snowbirdB. Canada is a favorite destination for snowbirdsC. snowbirds don’t like the weather in the NorthD. a snowbird has to own homes both in the South and in the NorthC（2019·四川成都棠湖中学期末）I was raised in a house where my sisters and I weren’t trusted by our mother to manage our own appearance. A few years ago, I was home for a visit when my mom, now in her early 70s, called me into her bedroom. We were about ready to leave for dinner. “I don’t know what to wear,” she complained. “You girls always look so good.”I paused in the doorway and looked at her，wondering if I’d misheard. “What do you mean?” I asked her. “You know what to wear.” “No,” she answered. “I don’t. Can you pick some for me?” I was so surprised.This was the same woman that, in 1989, told my younger sister she wasn’t allowed to leave the house wearing a pair of ripped（撕碎的）Jeans; the same woman that, in high school, called me while I was out at a party to ask if my hair was tied up. “You look better with it down.” she told me. Before I could answer I realized, suddenly, that my mother not only wanted my opinion, but needed it. I pulled a pair of blue jeans and a light blue sweater. “Wear this with your black shoes,” I told her. She did. My mother certainly doesn’t need anyone to take care of her. In fact, she still cares for my grandmother who lives with her. But with that question, my mother and I started the role reversal（转换）that happens to all parents and all children, from caregivers to receivers.Now, if I’m visiting or we’re together, it’s rare for her to wear anything without checking with me first. But every so often, it seems like she asks me just to be able to disagree with my answer and pick out something on her own. And when she does, I just tell her what I think of the way she looks. Sometimes it’s “great”, and sometimes it’s “awful”.28. How did the author react the first time her mother asked her for advice on clothes?A. She was happy to do something for her mother.B. She came to realize that her mother needed her care.C. She was worried that her mother was too old to live alone.D. She had no idea what was suitable for her mother.29. When the author gives her opinion about clothes, what does her mother do?A. She always accepts her suggestions happily.B. She sometimes chooses to follow her own ideas.C. She is often surprised by what the author says.D. She still shows uncertainty about what to wear.30. What’s the author’s purpose of writing this article?A. She wants to show what it is like to have a strict mother.B. She wants to remind readers to visit their parents often.C. She wants to stress her mother’s great influence on her.D. She wants to show how the roles of parents and their children reverse.第二节（共5小题；每小题2分，满分10分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项，选项中有两项为多余选项。

Period Three Discovering Useful Structures—RestrictiveRelative Clauses(1)感知以下课文原句，完成方框下的小题1.以上定语从句由关系词who，which，that，whose引导，修饰名词或代词，置于被修饰词的后面。
2.关系代词which，that，who在定语从句中可以作主语，也可以作宾语或表语；关系代词whose 在定语从句中作定语。
在复合句中，修饰某一名词、代词或整个主句的从句叫做定语从句。
被定语从句修饰的名词或代词叫作先行词，连接先行词和定语从句的词叫关系词。
关系词的主要作用是连接主句和从句，并在从句中充当一定的句子成分。
关系词分为关系代词和关系副词两种，关系代词有that，which，who，whom，whose等；关系副词有when，where，why等。
一、关系代词的用法1.who指人，在定语从句中作主语或宾语。

2.whom指人，在定语从句中作宾语，常可省略。

注意：(1)关系代词whom在口语或非正式文体中常可用who/that来代替。
The boy (who/whom/that) we saw yesterday is John’s brother.昨天我们看到的那个男孩是约翰的哥哥。
(2)在从句中作介词的宾语且直接跟在介词后时，用whom，不用who。
The man to whom you spoke just now is a relative of mine.刚才和你说话的男人是我的一个亲戚。
3.which指物，在定语从句中作主语或宾语，作宾语时可省略。
The gold medal (which) she won has been given to her old school.她获得的那块金牌已经被送给她的母校了。
4.that既可以指人，相当于who或whom；也可以指物，相当于which。
在定语从句中作主语或宾语，作宾语时可省略。
The woman (that/who/whom) I read about in the newspaper has just won a gold medal.我在报纸上读过相关报道的那位女士，她刚刚赢得一枚金牌。
The report (that/which) Mr Turner handed in was about the motor race.特纳先生递交的报告是关于汽车比赛的。
注意：(1)宜用that不宜用which的情况①当先行词是all，little，few，much，something，anything，everything，nothing，some等不定代词时。
All that can be done has been done.一切能做的都已经做完了。
②当先行词被all，every，some，any，little，much，the only，the very，the right，the last，just等修饰时。
Music is the only thing that interests me.音乐是唯一令我感兴趣的东西。
③当先行词是序数词、形容词最高级或被序数词、形容词最高级修饰时。
This is the most interesting story that I have ever read.这是我曾经读过的最有趣的故事。

⑤当主语是以which开头的特殊疑问句时。

②在非限制性定语从句中。
Have you ever read the book，which was written by a young girl?你读过这本由一个年轻女孩写的书了吗？③先行词本身就是that时。
What’s that which flashed in the sky just now?刚才在天空中一闪而过的是什么？④关系代词后有插入语时。
Here is the English grammar book which，I think，can help improve your English.这就是那本我认为能帮你提高英语水平的英语语法书。
(3)宜用who不宜用that的情况①当先行词是指人的不定代词时，如：one，ones，anyone。

②当先行词是I，you，he，they等人称代词时(常用于谚语中)。

5.whose通常指人，也可指物，在定语从句中作定语。

This is the person whose story surprised everybody.就是这个人的故事让所有人感到吃惊。
The classroom whose door is broken can hold 40 students.那间被弄坏了门的教室能容纳40个学生。
二、使用定语从句的注意事项1.关系代词在定语从句中作主语时，定语从句的谓语动词要和先行词的数保持一致。
The suitcase that/which lies on the ground is hers.地上放的那个手提箱是她的。
注意：“one of＋复数名词”作先行词，谓语动词用复数形式；“the only one of＋复数名词”作先行词，谓语动词用单数形式。
This is one of the books which were written by Charles Dickens.这是查尔斯·狄更斯所写的书的其中一本。
He is the only one of the boys in our class who has learned French.他是我们班男生中唯一一个学过法语的。
2.为避免关系词的重复，被关系代词所代替的成分不可在从句中重复出现。
[译]昨天晚上我们看的那部电影非常吓人。
[误]The film (that/which) we saw it last night is very frightening.[正]The film (that/which) we saw last night is very frightening.3.关系代词的省略。
(1)关系代词作主语时不能省略。
