8.We don't know how different our future will be in the future.We can only try to imagine it.
At first we think about human relationship.In the year 2050,we will use computers almost every day we will be making new friends through the Internet-even our husbands or wives will be met in this way.It will be much faster and easier for us.On the other hand,our relationships with people won't be as important as they are today-we will feel a little lonely.
Computers will also help us in many other activities in 2050.For example,they will be used by the children at school to make their learning easier.In addition,there will be much more other machines which will play a similar role as computers,like robots which will do the homework for us.
Spending holidays will also be completely different.Traveling to other planets or to the moon will he available for everyone.Means of transport will,of course,change,too.We will be using solar-powered ears,which will be much cleaner.
We could expect that the faster technological progress would lead to a more polluted environment.But it isn't true.We will pay more attention to protecting the environment.And,Scientists will probably find cures for many dangerous diseases,like cancer or AIDS.Therefore,our surroundings as well as health will be in better condition.
Although we can't predict the exact changes which will be made in the world,we often think about them.We worry about our and our children's future;we have expectations,hopes as well as fears.But I think we should be rather sanguine about our future.We should be happy and believe good things will happen.

51.Why will people probably feel a little lonely in 2050?B
A.Because the number of people will become much smaller.
B.Because there will be less face-to-face communication
C.Because people won't like making friends with each other
D.Because people won't communicate with each other much often.
52.The third paragraph mainly tells isC
A.that computers will do all the things for human beings
B.how people will use computers to communicate with each other
C.that machines like computers and robots will help people a lot
D.how people will use robots to do the housework
53.According to the passage,which of the following will happen in 2050?C
A.The relationship between people will be more important than today.
B.The way of spending holidays will be the same as that of today.
C.It won't be difficult for people to travel to other planets
D.Our environment will be much more polluted with a growing number of cars
54.The underlined word"sanguine"in the last paragraph most probably means"D".
A.disappointed    B.surprised     C.curious      D.optimistic
55.What does the passage mainly talk about?B
A.How people will communicate in the year 2050.
B.What our life will be like in the year2050.
C.How people will travel and spend their holidays in the year 2050.
D.What high technology will appear in the year2050.

分析 我们不知道我们的未来将如何不同,我们只能想象它.文章人际关系(从电脑对人际关系和生活便利两方面来讲)、度假、技术进步叙事,尽管我们不能语言未来的世界将会怎样,但我们仍然抱着积极乐观的态度.

解答 51-55  BCCDB

55.B 主旨大意题.文章主要对人际关系(电脑对人际关系和生活的影响)、度假、科学技术的未来进行预测.故选B项

19.One of our biggest fears nowadays is that our kids might some day get lost in a"sea of technology"rather than experiencing the natural world.Fear-producing TV and computer games are leading to a serious disconnection between kids and the great outdoors,which will change the wild places of the world,its creatures and human health for the worse,unless adults get working on child's play.
Each of us has a place in nature we go sometimes,even if it was torn down.We cannot be the last generation to have that place.At this rate,kids who miss the sense of wonder outdoors will not grow up to be protectors of natural landscapes."If the decline in parks use continues across North America,who will defend parks against encroachment(蚕食)?"asks Richard Louv,author of Last Child in the Woods.
Without having a nature experience,kids,can turn out just fine,but they are missing out a huge enrichment of their lives.That applies to everything from their physical health and mental health,to stress levels,creativity and cognitive(认知的)skills.Experts predict modern kids will have poorer health than their parents-and they say a lack of outside play is surely part of it; research suggests that kids do better academically in schools with a nature component and that play in nature fosters(培养)leadership by the smartest,not by the toughest.Even a tiny outdoor experience can create wonder in a child.The three-year-old turning over his first rock realizes he is not alone in the world.A clump of trees on the roadside can be the whole universe in his eyes.We really need to value that more.
Kids are not to blame.They are over-protected and frightened.It is dangerous out there from time to time,but repetitive stress from computers is replacing breaking an arm as a childhood rite of passage(通过仪式).
Everyone,from developers,to schools and outdoorsy citizens,should help regain for our kids some of the freedom and joy of exploring,taking friendship in fields and woods that strengthen love,respect and need for landscape.As parents,we should devote some of our energies to taking our kids into nature.This could yet be our greatest cause.
58.According to the passage,children without experiencing nature willA.
A.be less healthy both physically and mentally 
B.keep a high sense of wonder
C.be over-protected by their parents           
D.change wild places and creatures for the better
59.According to the author,children's breaking an arm is.C
A.the fault on the part of their parents           
B.the result of their own carelessness in play
C.the natural experience in their growing up      
D.the effect of their repetitive stress from computers
60.In writing this passage,the author mainly intends toB.
A.blame children for getting lost in computer games
B.show his concern about children's lack of experience in nature
C.encourage children to protect parks from encroachment
D.inspire children to keep the sense of wonder about things around.

3.I had a lot of teachers that I loved.However,the teacher I remember most was Mrs.Green from Marianna,Florida.She was my 5th grade teacher.Since I was a new student,she made my time there much more pleasant.I immediately began to like her.She was really funny and I knew that she liked me.She made learning fun.I remember one day for Christmas holidays,she taught us how to make ornaments(装饰物)from eggs.My parents still have some of the ornaments I made.
She made me leader for many group projects and that made me feel special.I think that would make any child feel special,especially when a child is in a new place with no friends.She made me want to be like that.Not to pick a"favorite"student,but to make every student feel that they are special.That year,I received the Presidential Academic Award(美国总统学术奖).I was really proud and so were my parents.
