2．（10 分）Children start out as natural scientists，eager to look into the world around them．Helping them enjoy science can be easy；there is no need for a lot of scientific terms or expensive lab equipment．You only have to share your children's curiosity．You only have to share your children's curiosity．There are suggestions on how to do it．

Firstly，listen to their questions．I once visited a classroom of seven﹣year﹣olds to talk about science as a job．The children asked me "textbook questions"

about schooling，salary and whether I liked my job．When I finished answering，we sat facing one another in science．Finally I said，"Now that we've finished with

1

your lists，do you have questions of your own about science？"

After a long pause，a boy raised his hand，"have you ever seen a grasshopper （蚱蜢）

eat？When I try eating leaves like that，I get a

stomachache．Why？" This began a set of questions that

lasted nearly two hours．

Secondly，give them time to think．Studies over the past 30 years have shown that，after asking a question，adults typically wait only one second or less

for an answer，no time for a child to think．When adults increase their "wait time"

to three seconds or more，children give more logical，complete and creative answers．

Thirdly，watch your language．Once you have a child involved in a science discussion，

don't jump in with "That's right" or "Very good"．These words work well when it comes to encouraging good behavior．But in talking about science，quick praise

can signal that

discussion is over．Instead，keep things going by saying "That's interesting" or

"I'd never thought of it that way before'，or coming up with more questions or ideas．

Never push a child to "think"．It doesn't make sense；children are always thinking，without your telling them to ．What's more ，this can turn a conversation into a performance．The child will try to find the answer you want，

in as few words as possible，so that he will be a small target for your disagreement．

Lastly，show；don't tell．Reallife impressions of nature are far more impressive than any lesson children can learn from a book or a television program．Let children look at their fingertips through a magnifying glass （放大

镜），and they'll understand why you want them to wash before dinner．Rather than

1

saying that water evaporates （蒸发），set a pot of water to boil and let them watch

the water level drop．

（1）According to the passage，children are natural scientists，and to raise their

interest，the most important thing for adults to do is ．

A.to look into the world around

B.to share the children's curiosity

C.to explain difficult phrases about science

D.to supply the children with lab equipment

（2）In the second paragraph，the word "list" could best be replaced by ．

A.all the questions

B.questions about the author's job

C.questions from textbooks

D.questions of his own

(3)According to the passage，children can answer questions in a more logical，

complete and creative way if adults ．

A.ask them to answer quickly

B.wait for one or two seconds after a question

C.tell them to answer the next day

D.wait at least for three seconds after a question

(4)The author mentions all of the following techniques for adults to share with their children's

curiosity except that adults should ．

A.tell their children stories instead of remembering facts

B.offer their children chances to see things for themselves

C.be patient enough when their children answer questions

D.encourage their children to ask questions of their own

3．（7.5 分）

One half of the brain remains on high alert （警惕）during the first night of sleep

in a new space．

1

Over the course of three experiments on 35 young，healthy volunteers，researchers measured brain activity during two nights of sleep．They found that part

of the left side of the brain remained more active than the right side only on the first

night，specifically during a deep sleep stage．

"When you sleep in a new place for the first time，a part of one side of the brain seems to stay awake，so you could wake up faster if necessary，" said senior study

author Yuka Sasaki of Brown University．

While this may be bad news for business travelers who regularly make brief overnight

trips，it may not be as troublesome for people who go away for longer periods of

time，Sasaki added by email．

To see how being in a strange place affects sleep，Sasaki and colleagues performed a series of lab tests on their subjects．

When they stimulated （刺激） the left side of the brain with sounds in the right ear during deep sleep on the first night， that led to greater possibility of waking and faster action upon waking， than if sounds were played in the left ear to affect the right side of the brain． On the second night，there wasn't any difference in reactions to tests between the left and right sides of the brain，even during deep sleep．This suggests that there is a first﹣night ﹣only effect specifically in one side of the brain during deep sleep， the authors conclude． One limitation of the new study is its focus on healthy volunteers， which means the results may not apply to people with sleep disorders， the authors note．While it's possible that the findings may explain poor sleep among frequent t ravelers，t he study wasn't designed to test whether these "first night effects" continue to happen to people every time they hit the road， said Patrick Finan， a researcher at Johns Hopkins University

School of Medicine in Baltimore．

（1）What does the underlined word "this" in Paragraph 4 refer to？

A.The finding of the new study．

1

B.The advice of the researchers．

C.The process of measuring brain activity．

D.The suffering of the volunteers．

（2）If people stay at a new place for more than one day，．

A.they can wake faster on the second night than on the first night．

B.there won't be any difference to them on the second night．

C.they suffer from sleep disorders．

D.the first night effects may not last．

（3）What is the problem of the new study？

A.Some volunteers suffer from sleep disorders．

B.It does not find out the different reactions of the ears．

C.The result may not apply to all people．

D.There are not enough volunteers．

4．（10 分）As I was busy working on my work plan in my bedroom，I could hear my four children playing upstairs．Suddenly，I heard the children running down the stairs

and shouting，"Freddie，Freddie．" I heard the word "window" and rushed

outside，heart in mouth．My three﹣year old son Freddie was lying on his side on

the ground．I cried for my husband Simon to dial 999 and within minutes the air

ambulance arrived．They quickly took him in the helicopter （直升机）．During

the flight，Freddie was looking at me and I remembered thinking was a good

sign，but then his eyes began to roll．As the doctors tried to stabilize

（稳定）him，I couldn't believe what was happening．

When we arrived at the hospital in Portsmouth，there were some doctors and nurses waiting for us and they immediately set to work on Freddie．I was

hopelessly wishing everything would be alright，but Freddie had broken his skull in

two places and blood clots were forming in his brain．He needed operation，and

only a doctor at another hospital in

Bristol could do it．This meant another helicopter ride，but we couldn't go with

1

Freddie

because there was no enough space．Simon and I drove the long 130 miles from our home in north Devon in silence．Neither of us dared say what we were thinking，"What if we get there and he's dead？" "Is he going to be brain﹣damaged？"

Freddie was just coming out of operation when we arrived．The surgeon said it had gone well．When I finally saw him，I hardly recognize my child ﹣he was covered in tubes （管子）and there were wires coming out of his head．On the third day，Simon went home to see our three girls and to pick up some clean clothes for us．While he was gone，the pressure in Freddie's brain suddenly increased．He was taken into operation room again and this time I fell apart．Luckily，the operation managed to stabilize Freddie．After almost a week，Freddie was finally woken up．When he opened his eyes，he looked at me．He didn't say anything，but I knew straight away that it was my old Freddie，and that he was going to be alright．Over the next two weeks，his recovery went well．After help with learning to swallow again and encouragement with speaking，he was soon playing with his Gruffalo cards and eating meals by himself．

I still don't know how the accident happened，but we got some idea from our girls．Clearly Freddie and Minnie had been sitting on the window ledge，and Freddie must have opened it to look out and fallen 20 feet onto the ground below．The guilt （内疚）I feel is awful ﹣for weeks I was full of "if onlys"，and we put window locks everywhere．Six months later，although the accident seems a lifetime ago，it has changed me．I feel differently about life now．I've left my job to put my children first．I want to spend every minute with them．

（1）Why did the author's son have to be moved to another hospital in Bristol？

A.Because no doctors were on duty in the first hospital that day．

B.Because the author wanted his son to stay in a hospital nearer her home．

1

C.Because no doctors in the first hospital knew the injuries to the author's son．

D.Because no doctors in the first hospital could do operation on the author's son．

（2）When the author finally saw her son，she could hardly recognize him

probably because his face ．

A.was seriously injured

B.was filled with small pipes

C.was too pale to be recognized

D.was covered by a piece of cloth

（3）On the third day after being taken to the hospital，．

A.the author's son finally opened his eyes．

B.the situation of the author's son suddenly worsened

C.the author's son was finally out of danger

D.the author's son did not need any more operation

（4）After the accident，what did the author probably learn？

A.Life is full of "if onlys"．

B.Being a single mother is not easy．

C.Children are more important than work．

D.Accidents can happen to every kid．

only have to share your children's curiosity．There are suggestions on how to do

【分析】本文是一篇说明文，说明了孩子们开始作为自然科学家，渴望观察他

们周围的世界，帮助他们享受科学很简单．

【解答】1．B．细节理解题，根据文章第一段"Helping them enjoy science can be easy；there' s no need for a lot of scientific terms or expensive lab equipment．You

only have to share your children's curiosity．帮助他们享受科学是很容易的，不需要

太多的科学术语或昂贵的实验室设备，你只需要分享你孩子的好奇心"可知为了能

够引起孩子对自然的兴趣，我们唯一可以做的就是分享他们的好奇心，让他们的

好奇心的到满足．故选B．

2．C．词义猜测题．由第一段"The children asked me"textbook questions"about schooling，

salary and whether I liked my job．以及When I finished answering，we sat facing

one another in silence．Finally I said，"Now that we're finished with your lists，do

you have questions of your own about science？孩子们问我关于学校教育、薪水和

我是否喜欢我的工作的"课本问题"．当我回答完后，我们面面相觑地坐在一

起．最后，我说："既然我们已经完成了你的清单，你对科学有没有自己的问题？""我回答完他提的问题，就问他是否有关于自然科学的问题要问我，由此推

断lists 指的是孩子们问我一些关于学校、薪水以及我是否喜欢我的工作的"教科

书式问题"．可知本题答案为C 选项．

3．D．细节理解题，根据文章第四段"When adults increase their"wait time"to

three seconds or more，children give more logical，complete and creative answers．当成年人把他们的"等待时间"增加到3 秒或更多时，孩子们会给出更

1

合理、更完整和更有创造性的答案"可知

成人提出问题以后，等 3 秒及其以上时间，可以让孩子有时间思考问题．那样

他们就能回答的更具有逻辑性和创造性，结合选项，故选D．

4．A．推理判断题．根据文章第四段"When adults increase their"wait time"to three

seconds or more，children give more logical，complete and creative answers．当成

年人把他们的"等待时间"增加到 3 秒或更多时，孩子们会给出更合理、更完整和

更有创造性的答案"给孩子足够的时间思考问题，当孩子回答问题时要足够耐心，

C 正确；文章第五段"keep things going by saying"That's interesting"or"I'd never

thought of it that way before"，or coming up with more questions or ideas．通过说"

那很有趣"或"我以前从来没有这么想过"或提出更多的问题或想法来保持进展" 要

鼓励孩子们多提问题，D 正确；文章最后一段"Let children look at their fingertips

through a magnifying glass（放大镜），and they'll understand why you want them to

wash before dinner 让孩子们透过放大镜看他们的指尖，他们就会明白你为什么要

他们在饭前洗衣服"可知让孩子们用放大镜观察他们自己的脚印…让他们自己多

发现事物，B 正确．由此可知，B\C\D 在文中均有提及，A 文中没提到．故选

A．

【点评】阅读理解考察学生的细节理解和推理判断能力，做细节理解题时一定

要找到文章中的原句，和题干进行比较，再做出正确的选择．在做推理判断题

不要以个人的主观想象代替文章的事实，要根据文章事实进行合乎逻辑的推理

To see how being in a strange place affects sleep，Sasaki and colleagues performed a series of lab tests on their subjects．

When they stimulated （刺激）the left side of the brain with sounds in the right ear during deep sleep on the first night，that led to greater possibility of waking and faster action upon waking，than if sounds were played in the left ear to affect the right side of the brain．On the second night，there wasn't any difference

in reactions to tests between the left and right sides of the brain，even during deep sleep．This suggests that there is a first﹣night

﹣only effect specifically in one side of the brain during deep sleep，the authors conclude．One limitation of the new study is its focus on healthy

volunteers，which means the

results may not apply to people with sleep disorders，the authors note．

While it's possible that the findings may explain poor sleep among frequent travelers，the study wasn't designed to test whether these "first night effects" continue to happen to people every time they hit the road，said Patrick Finan， a researcher at Johns Hopkins University

School of Medicine in Baltimore．
