It is easy for many people to catch a cold in the springtime or
fall. It makes us wonder if scientists can send a man to the moon, why can’t
they find a cure for the common cold? The answer is easy. There are actually
hundreds of kinds of cold viruses out there. You never know which one you will
get, so there isn’t a cure for each one.
&&&&&&&& When
a virus attacks your body, your body works hard to get rid of it. Blood rushes
to your nose and cause a block in it. You feel terrible because you can’t
breathe well, but your body is actually eating the virus. Your temperature goes
up and you get a fever, but the heat of your body is killing the virus. You
also have a runny nose to stop the virus from getting into your cells. You may
feel very uncomfortable, but actually your wonderful body is doing everything
it can to kill the cold.
&&&&&&&& Different
people do different things to deal with colds. In the United States and some
other countries, for example, people might eat chicken soup to make themselves
feel better. Some people take hot baths and drink warm liquids. Other people
take medicine to stop various symptoms (症状) of colds.
&&&&&&&& There
is one interesting thing to note —some scientists say taking medicines when you
have a cold is actually bad for you. The virus stays in you longer because your
body doesn’t have a way to fight it and kill it. Bodies can do an amazing job
on their own. There is a joke, however, on taking medicine when you have a
cold. It goes like this:
&&&&&&&& It
takes about one week to get over a cold if you don’t take medicine, but it
takes only seven days to get over a cold if you take medicine.

名词在英语词汇中占有较大的比例，历年中考试题都要涉及，分值在2-3分，考点常分布在单项选择、完形填空和完成句子中。近几年的中考在淡化语法的同时，突出了语言的交际性和实用性，中考热点主要集中在：
1、正确识别可数名词和不可数名词；
2、掌握可数名词复数形式的构成；
3、正确判断某些常用名词在特定语境中的可数和不可数性；
4、掌握名词所有格的基本形式及一般用法。
攻克方法：要全面掌握中学阶段所学的英语知识，系统地做好语法归纳并有意识地多记一些名词惯用语，尤其是与汉语不同的一些特殊用法。

Making Our Team Work Best
Learning in school, we often work in small groups．But why? Is it necessary to
work with others? What if you feel comfortable doing a job by yourself ? In
reality, however, after leaving school, you will find out that almost all work
in many fields is done in teams．
Actually, a team is a group of individual people brought together in
order to complete a task which cannot be efficiently finished by any member of
the group alone．The
group may be temporary or it may stay together for a long period．
A type of team that we are familiar with are sports teams, which are
made up of a certain numbers of players．They work together to win a match．In fact, different numbers have different skills
in a team．A team
can only work well when all their members cooperate．The atmosphere in a team
affects the performance of the team, so the social relations within the team
are important．
Teams require leaders, and people who create ideas, who develop
ideas, and people whose role is to comment and help improve plans．People who identify problems
and suggest solutions are needed in a team, too．Every team member works in their most efficient
way to make the whole team work best．
Regulations and rules help teams work well．But be careful．Working in a team, we have to
take into account how each individual member can work best．Some may work best on task
others work best in groups．How the group task is divided depends on the personalities and
abilities of the individual in the group．
In a dynamic （充满活力的） team, people with quite different personalities work well together．Actually, their differences are
the strength of the team．To make the best of working with our classmates, or to make our team
work best, it is important to recognize the strengths and weaknesses of each
individual of the group．
To know someone's personality type and ability is to know a great
deal about that individual person, or to understand that person．To understand means that we can
build strong relationship between members of a team, and make the best use of
each others' talents．
&&&&&&&& A．Knowing about Team Members
&&&&&&&& B．Functions of Rules and
Regulations
&&&&&&&& C．Team Members and Their Roles
&&&&&&&& D．How a Team Works
&&&&&&&& E．A Sports Team
&&&&&&&& F．The Definition （定义） of a Team
With five breakout （破纪录的） games, Jeremy Lin has
become the NBA's newest star．
In the New York Knicks' 92-85 won over the Los Angles Lakers last
Saturday, Lin had a career-high 38 points．A day later, he led the Knicks to their fifth victory, 100-98 to
Minnesota Timberwolves．In his previous games, Lin, 23, had 23 points against the
Washington, 25 points against New Jersey and 28 against Utah in his first start．
Lin is smart．Before graduating from high school in California, he had sent his
application to all the Ivy League Schools （常青藤联盟）．He only got into Harvard and Brown, and he chose Harvard．In 2010, Lin graduated with a
degree in economics．
Lin is the first Chinese-American player in the NBA．He was born in the US and his
family is Asian．Although
not born in China, Lin has attracted nearly all Yao Ming's old fans, who see
him as a powerful role model．
He started off on the Golden State Warriors．Lin first signed with the
Warriors in July, 2010, but seldom played in games before the start of the
fourth quarter．His
first time on the court for the Warriors earned him seven points, three
rebounds （篮板球） and two
assists in just 11 minutes．
He is really perfect for the Knicks．The New York Knicks has been in need of a reliable
point guard and to Mike D'Antoni, the Knicks coach who's going through a
difficult season, Lin is a most unexpected figure．&Lin just does everything easy and the rest
of the guys around him are playing the way we want to,& D'Antoni said．&I think it's for real,
and it can only get better．&
1.In which team did
Lin start his career in NBA?
&&&&&&&& A．the New York Knicks．&&&&&&&&&
&&&&&&&&&&
&&&&&&&& B．The Golden State Warriors．
&&&&&&&& C．Minnesota Timberwolves．&&&&&&&
&&&&&
&&&&&&&& D．The Los Angles Lakers．
2.From the passage,
we learn that ___．
&&&&&&&& A．the New York Knicks has never
been defeated
&&&&&&&& B．Lin is an American-Chinese
basketball player
&&&&&&&& C．most of Yao Ming's fans take
Lin as a great role model
&&&&&&&& D．after graduation from Harvard,
Lin signed with the Knicks
3.From the passage,
it can be inferred that ____．
&&&&&&&& A．Lin is the team leader of the
Knicks
&&&&&&&& B．the Knicks' success only
depends on Lin
&&&&&&&& C．the Knicks'coach puts strong
hopes on Lin
&&&&&&&& D．the Knicks is sure to win the
season this year

purpose of writing the report is ____．
&&&&&&&& A．to show his support for the
Knicks
&&&&&&&& B．to express his love for Jeremy
Lin
&&&&&&&& C．to report the progress of the
Knicks
&&&&&&&& D．to introduce a newest rising NBA
star
Have you ever wondered why birds sing? Maybe you thought that they
were just happy．After
all, you probably sing or whistle when you are happy．
Some scientists believe that birds do sing some of the time just
because they are happy．However, they sing most of the time for a very different reason．Their singing is actually a
warning to other birds to stay out of their territory．
Do you know what a &territory& is? A territory is an area
that an animal, usually the male, claims as its own ．Only he and his family are
welcome there ．No
other families of the same species are welcome．Your yard and house are your territory where only
your family and friends are welcome．If a stranger should enter your territory and threaten you, you
might shout．Probably
this would be enough to frighten him away．
If so, you have actually scared the stranger away without having to
fight him．A bird
does the same thing．But he expects an outsider almost any time, especially at nesting （筑巢） season．So he's screaming （高声尖叫） all the time, whether he
can see an outsider or not．This screaming is what we call a bird's song, and it is usually
enough to keep an outsider away．
Birds sing loudest in the spring when they are trying to attract a
mate and warn others not to enter the territory of theirs．You can see that birds have a
language of their own．Most of it has something to do with attracting mates and setting up
territories．
1.Some scientists
believe that most of the time birds' singing is actually
A．an expression of happiness&&&&&&&
&&&&&&&&&&&&&&&&
B．a way of warning
C．an expression of
anger&&&&&&&&&&& &&&&&&&&&&&&&&
D．a language of their own
2.What is a bird's
&territory&?
A．A place where a bird may shout at the top of its voice．
B．A place where other bird families are not accepted．
C．An area for which birds fight against each other．
D．An area which a bird considers to be its own
3.Why do birds keep
on singing at nesting season?
A．Because their singing helps frighten outsiders away．
B．Because their singing helps get rid of their fears．
C．Because they want to find outsiders around．
D．Because they want to invite more bird friends．
4.How does the writer
explain birds' singing?
A．By comparing birds with human beings．&&&&&&&&&&&
B．By reporting
experimental results．
C．By describing birds'daily life．&&&&&&&&&&&&&&&&&&&
D．By telling a
bird's story．
How many coins do you have in your pocket right now? Three? Two? Or
one? With a phone card, you can make up to 200 calls without any charges at all．
★What do you do with it?
Go to a telephone box marked &Phone-card&．Put in your card to start, make
your phone call and when you have finished, the screen will tell you how much
is left on your card．It costs no extra for the cards, and the calls cost 10 p（便士） per unit, the same as any
other pay-phone call．You can buy it in units of 10, 20, 40, 50, or 100．
★Appear in a shop nearby．
Near each card-phone place, you will find a shop where you can buy one．They are at bus, train or metro
stations．At
universities, hospitals, clubs, restaurants and shopping centers, you can also buy
it．
★No more broken pay-phones．
It is possible that many pay-phones don't work because they have
been damaged． There
are no coins in a card-phone to excite the thieves' interest in it．So you are not probably to find
a broken one．
Get a phone-card yourself and try it out．Or get a bigger wallet．
1.The passage is most
probably ____．
&&&&&&&& A．a
warning&&&&&&&&&&&&&&&&&&&&&
&&&&&& B．a notice
&&&&&&&& C．an
advertisement&&&&&&&&&&&&&&&

&one& means ____．
&&&&&&&& A．a
shop&&&&&&& &&& B．a coin&& &&&&&&&& C．a pay-phone&&& & D．a phone-card

than others

with a phone card

&Get out of the plane!& Justin shouted．Teddy and he dropped to the
ground,．．．
When Kathy and Victor reached the edge of the meadow （牧场）flames of the fire were
shooting more than five meters into the air．
Kathy couldn't believe what she was seeing．One glance told her they needed
medical attention immediately．She questioned Victor, &Are you able to find someone nearby for
help?&
&There
are no farmers, nor villagers nearby,& he replied．
&I'm a distance runner, and I'll go for help．& Looking at the seriously
injured men, Kathy said to Victor, &It may take me several hours to get
out．& She
started out．
When she was 23, Kathy set a women's record in a Marathon of 42
kilometers．But
now she was running the race of life．She had nearly 30
kilometers of hard wilderness to cover to get help．
Kathy had been running for two hours．．The country path was growing vague （模糊）．She stopped to take a quick compass （指南针） reading．Yes, she had run almost for
more than 20 kilometers．Her heart fell, her muscle aching．And finally she saw her car in the distance．
She
jumped into the car and sped away．She reached a holiday house and called the police．
During the wait, she walked around, relaxing her legs and drinking
water．It took
almost two hours for a police helicopter to reach her at the trail （小路） end．They needed her for one more
task．

himself&&&&&&&&&&&&&&&&&&

ABCA短文属于说明文。为了学生的乘车安全，列出了几条有关的规则。1.细节理解题。从第1条规则中“When you are waiting for the bus, you should wait at the bus stop”得知。2.综合理解题。从第5、６条规则中得知Ａ项不正确；Ｃ、Ｄ太片面，因为过马路时要左右看。Ｂ项等绿灯是正确的。3.细节理解题。从第4条规则中“Never bend down near the bus when you walk to or from the bus stop.”得知。4.主旨大意题。根据短文开头部分的交代，可知“take buses to school”“rules”是关键词；另外后面所列的规则都是为了学生的乘车安全。

The worst danger is a house on fire when people are asleep. Always be ready to leave through a window into the garden by making sure you can open it if necessary. If you should be on holiday in a tall building or hotel, make sure you know where the fire escape（太平梯） is . When you can’t find any way out, try to find pieces of cloth and make a rope to get out of a window to safety. If you smell burning in your home, get out right away. If you can’t breathe properly because of smoke on your way out, crawl（爬行） on your hands and knees because smoke rises and the air will be cleaner near the floor. Smoke is a killer and more people have died from breathing it in than actually being burnt.Fire in a cinema, hall or public place often means people pushing to reach a door. Keep your head up with arms up in front of your chest（胸）.This protects your chest and gives you the best chance to breathe. Above all, don’t get frightened!【小题1】In a room filled with smoke ,you’d better crawl on the floor because__________.A．you won’t get burnt.B．the floor is cleanerC．there is less smoke near the floorD．you won’t breathe any smoke【小题2】Which of the following is NOT true?A．In a fire, more deaths are caused by smoke.B．The most important thing is not to be frightened in a fireC．When a public place is on fire, people usually push to leave.D．Be ready to leave a burning house through a window if there is a garden down below.

Very few people enjoy exams. I don’t, either. And although I tell myself not to worry about them, I always do! So I’m not surprised that my students worry about them, too, even though they usually don’t need to. Because they are afraid of failing. However, since it is hard not to worry at all, we all must try not to worry too much. Why? Because worrying makes exams worse! How to do this?Ask the teacher about how to revise and about exam skills—how to work when you are in the exam. Good students don’t wait until the week before an exam. They study all through the year. It is not possible to learn everything at the last minute. So don’t leave it till then.If you start planning and working for each exam early and you make sure that you understand what you’re studying, then, when it is over, you’ll be able to say, “What a good exam that was!”Take a short rest during your time of work and revision. If your mind is tired, it won’t remember well. Work at the time when you know you’ll work at your best.If you’re studying in the evening, don’t go straight to bed afterwards. Your mind will still be “going round and round”—thinking too much. Do something else, maybe walk or get exercise. Choose something that will relax you, and make you think of other things.If you feel bad, talk to someone about your worries. But don’t be too relaxed! Some stress over exams makes you work hard for them.【小题1】How does the writer feel about exams?A．Excited.B．Bored.C．Worried.D．Surprised.【小题2】Why are the students afraid of exams?A．Because they are afraid of failing.B．Because they want to get full marks.C．Because exams are usually hard.D．Because their teachers will be angry at their bad grades.【小题3】Which is NOT mentioned in the passage?A．Good students don’t wait until the week before an exam.B．Start planning and working for each exam early.C．If you don’t know how to work for an exam, ask the teacher about it.D．You should sleep well before the exam.【小题4】According to the passage, if you feel bad, you’d better _____.A．take a short restB．tell someone about your worriesC．walk or get exerciseD．keep busy working and forget your worries

In Britain you’re allowed to drive a car when you’re seventeen. You have to get a special two-year driving license before you can start.
