8.Cause and effect is one way to explain things that happen around us.Many things happen because something caused or influenced them to happen.Sometimes it is hard to look at a cause and find out what caused or influenced them to happen.Sometimes it is hard to look at a cause and find out what causes the effect.It may help you to start with the effect and use your reasoning(推理的) skills.Think about all the things you know that could be reasons for the effect you can see.
For example,you may see someone putting on a heavy jacket.This is the effect.To look for a cause,think to yourself,"What would take someone put on a heavy jacket?"Maybe the person is going outside into very cold weather.Maybe the person works in the penguin pen(企鵝圈養(yǎng)地) at Sea World.Maybe the person is going to visit an ice skating rink where the air is kept very cold.All of these things could be a cause for putting on a heavy jacket.
Now,think about a second example.The effect is a boy named Abi has to go to the head teacher's office.What are the possible causes?Maybe he bullied(欺負(fù)) another student.Maybe he is just being picked up early.Maybe he is being given a prize!
Here is another example for you to think about its cause and effect.Cait,13,was trying to fall asleep when her 8-year-old brother,Doug,came into her room.He looked around a bit,but seemed really out of it.Then Doug went back into the hallway and stood there looking straight up at the hall light for quite a while.Little brothers can be very strange,but this was really much too strange.Cait's father appeared and explained that Doug was sleepwalking.What's the cause end effect,could you tell?

根據(jù)材料內(nèi)容選擇最佳答案,并將其標(biāo)號(hào)填入題前括號(hào)內(nèi).

2.It's Friday evening.My daughters,3 and 9,sigh(嘆息) when I gently take the iPads away from their laps.One by one,our screens are turned off.We light the candles and sit down to have a big meal.
Most people in our lives know they will not be able to contact us by using computer or mobile phones for 24 hours.And so it has gone,every week for three years.We call it our"Technology Shabbat(科技安息日)"which lasts from sunset on Friday to sunset on Saturday.
I first understood the importance of disconnecting in 2008,when my father was told that he had got brain cancer.Some days he would have only one good hour,and I wasn't willing to be disturbed when I was with him,so I'd turn off my mobile phone.
Soon after,encouraged by National Day of Unplugging(全國(guó)斷網(wǎng)斷電日) on March 1st,my husband and I decided to unplug for one full day every week.
During our"Technology Shabbats",time slows.Our Saturdays now feel like mini-vacations.We drive our car or ride our bike.We,with our kids,work in the garden,play board games and cook meals.I feel more balanced.I feel like a better mother,wife and person.
Keeping a balance between the good and the bad of technology is my lasting state.The technology we've created makes it possible for us to share knowledge and take in carious ideas all over the world.But the technology also take something away from us.When we stay up late at night linking(連接) from website to website or sending messages or e-mailing,we click again,and again,and again until we've overloaded(超負(fù)荷的).
When we rush into the time full of high technology,it's necessary for us to pay attention to what we are doing online and when we should go off.
I will always remember the most important thing in my family:"Technology Shabbat".
32.When is"Technology Shabbat'in the writer's family?B

A.save energy             
B.enjoy life together
C.stay away from others    
D.follow National Day of Unplugging
34.What do the writers family NOT do during their"Technology Shabbats"?D
A.They drive their car or ride bikes for mini-vacations.
B.They light the candles and sit down to have a big meal.
C.They work in the garden,play board games and cook meals.
D.They stay up late at night linking from website to website.
35.What's the main idea of this passage?A

B.A woman should Iearn to be a good mother or wife.
C.People need to stay away from technology properly.
D.People had better not send messages,e-mail or chat online.

3.Is the world too crowded?Well,that's a hard question to answer.It's all a matter of perspective(視角).In Montana,you might drive for a mile in any direction and not see another human being.In Macao,60,000people live in every square mile!
What is true is that the world's population doesn't stay the same.It has been increasing at a very fast rate(比例).That's in part because in each generation(代) these are more people who then have children than in the last generation.
Five hundred years ago,the population of the world was about 460million.In 1900,the world's population was under 2billion(十億).Right now it is doubling every 40years.That means,if this rate of growth continues,when you are a parent,there will be twice as many people on earth as there are now.Wow!Now that's a whole lot of people!Soon the world's population will probably reach 7billion.Some people worry about that!But there is a lot of disagreement about just how many people on earth equals(相當(dāng)于) too many people.But everyone agrees that the more people there are,the more resources(資源) the world needs to feed,house and take care of all of them,and the more need there is to think carefully about how we live and use the earth's resources.

61.From the first paragraph we can know thatB.
A.Montana is too crowded                  B.Macao is too crowded
C.the world is too crowded                 D.the world is not too crowded
62.The population is increasing fast partly becauseD.
A.people live longer than before
B.there are less wars than before
C.medicine is developing faster than before
D.more couples now would like to have children than before
63.What was the world's population 100years ago?B
A.450million.B.About 2billion.C.40billion.D.7billion.
64.The writer thinks that with the population increasing,we shouldC.
A.find more resources                    B.use more resources
C.think about our ways of living            D.move to other places
65.From the passag we can learn that the writerD.
A.thinks the world already has too many people

13.We all dream about things that we would like to do we hope to achieve in the future.But are everybody's dreams the same?Here are some of the findings of a survey about hopes and dreams,in which thousands of students across China took part in it.
What are the hopes of teenagers?
We received several different answers to the question:what would you like to do after finishing your education?It seems some students would like to start work as soon as possible,so that they can help provide better lives for their parents.Other students hope to continue studying after finishing school and to go to university.Although money is important,many teenagers said they want to do jobs they enjoy.According to the survey,the most popular choice of job is computer programming.
What are the dreams of teenagers?
Teenagers have all kinds of dreams.Some are more realistic than others.For example,many students said they would like to be volunteers if Beijing could hold the World Cup,maybe working as translators or tour guides.And quite a few said they dream of going to the moon one day.
According to the survey,less realistic dreams are also common,but many students reported that they were willing to work hard to achieve their dreams.Quite a few dream of becoming famous,perhaps famous sports people or singers.Some said they'd like to go on exciting trips; one students said she'd love to sail across the Pacific Ocean.And then there are dreams that are impossible; three students said they'd like to be able to fly!
Conclusion It was clear from the survey that teenagers have similar hopes.It seems that most students hope to have a good education and find a good job.On the other hand,students dream of very different things:good things,and even crazy things.It is very important to dream,so hold on your dreams; one day they may just come true.

Hopes of teenagersSome students hope to start working as soon as possible.
Others hope to continue studying after finishing school and to go to university

Dreams of teenagersSome students have more realistic dreams such as working as volunteers at the 2008Olympics,etc.
