Children start out as natural scientists, eager to look into the world around them.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.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 silence.Finally I said, “Now that we’re finished with 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 smaller target for your disagreement.

       Lastly, show; don’t tell.Real-life 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, and they’ll understand why you want them to wash before dinner.Rather than saying that water evaporates, set a pot of water to boil and let them watch the water level drop.

According to the passage, children can answer questions in a more logical, complete and creative way if adults ______.

       A.a(chǎn)sk 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

In which of the following paragraph(s) does the author tell us what to say to encourage children in a science discussion?

       A.The second and third.   B.The fourth and fifth.

       C.The fifth and sixth.       D.The seventh.

In the last sentence of the first paragraph, the word “l(fā)ists” could best be replaced by

       A.a(chǎn)ny questions                   B.a(chǎn)ny problems

       C.questions from textbooks      D.a(chǎn)ny number of questions?

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 reciting 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

Social networking websites are causing alarming changes in the brains of young users, a famous scientist has warned.Sites such as Facebook, Twitter and Bebo are said to shorten attention spans (幅度), encourage instant satisfaction and make children more self-centered.
Warnings from neuroscientist (神經(jīng)系統(tǒng)科學(xué)家) Susan Greenfield will disturb the millions whose social lives depend on surfing their favorite websites each day.But they will strike a chord (弦) with parents and teachers who complain that many teenagers lack the ability to communicate or concentrate away from their screens.
More than 150 million use Facebook to keep in touch with friends, share photographs and videos and post regular updates of their movements and thoughts.A further six million have signed up to Twitter, the "micro-blogging" service that lets users exchange text messages about themselves.But while the sites are popular and extremely profitable, a growing number of psychologists and neuroscientists believe they may be doing more harm than good.
Baroness Tarot, an Oxford University neuroscientist believes repeated exposure could rewire the brain.Computer games and fast-paced TV shows were also a factor, she said."My fear is that these technologies are weakening the brain to the state of small children who are attracted by buzzing noises and bright lights, who have a small attention span and live for the moment." "I often wonder whether real conversation in real time may eventually give way to these easier and faster screen dialogues, in much the same way as killing and butchering an animal to eat has been replaced by the convenience of packages on the supermarket shelf," she said.
Psychologists have also argued that digital technology is changing the way we think.They point out that students no longer need to plan their term papers before starting to write—thanks to word processors they can edit as they go along.
A study by the Broadcaster Audience Board found teenagers now spend seven and a half hours a day in front of a screen.Educational psychologist Jane Healy believes children should be kept away from computer games until they are seven.Most games only excite the "flight or fight" areas of the brain, rather than the areas responsible reasoning.
Sue Palmer, author of Toxic Childhood, said: "We are seeing children's brain development damaged because they don't engage in the activity they have engaged in for thousands of years.I'm not against technology and computers.But before they start social networking, they need to learn to make real relationships with people."
【小題1】.
According to the passage, social networking websites might _____.

A.make young users more selfish
B.lengthen young users' attention span
C.encourage young users constant satisfaction
D.help young users communicate better with their families
【小題2】.
A neuroscientist may worry that sites like Facebook may ______.
A.help children learn to make real relationships with people in society
B.encourage students not to plan their term papers before starting to write
C.disturb those whose social lives depend on surfing their favorite websites
D.make real conversation in real time give way to easier and faster screen dialogue
【小題3】.
From the passage we can infer that _____.
A.Baroness Tarot agrees websites cause small children's small attention span
B.Jane Healy believes computer games can do good to children's reasoning
C.Susan Greenfield's warnings have been brought to wide public attention
D.Sue Palmer's book Toxic Childhood discusses the development of networking
【小題4】.
What is the purpose of this passage?
A.To tell us the conflict between neuroscientists and psychologists on websites.
B.To present some negative opinions on social networking websites.
C.To offer advice on the problem of brain damage caused by social networking.
D.To analyse how social networking websites cause damage in the brains of teenagers.

YOUR mom might cook a bowl of noodles for you on your birthday. But in the US, a mom makes a cupcake for her children on their birthday.
Cupcakes are small, round cakes topped with frosting (糖霜). It has been an American tradition that moms bring cupcakes to the classroom to celebrate their child’s birthday.
But recently some doctors have called for this to be banned. They believe cupcakes contribute to child obesity.
Despite their good intentions, however, some people believe that experts are interfering (妨礙) with American culture. The cupcake is seen as American as apple pie — only prettier.
According to Marion Nestle, a professor of nutrition at New York University, the cupcake is the most democratic (民主的) of desserts. As they are small enough for one person, you don’t have to share your cupcake with anyone — it’s all yours. They are also all the same size, so there can’t be any cries of “she got the bigger piece!”
Each bite can taste different depending on how much icing you have. It is a lesson in self- determination. Some people eat only a little of the frosting every time, others have it all in just one bite.
In recent years, eating a cupcake has become as trendy as having a cup of Starbucks coffee.
Democratic presidential candidate Hillary Clinton jokingly promised on a talk show that if she was elected president, she would give everyone a cupcake on her birthday.
Ruth Reichl, editor-in-chief of Gourmet magazine, explains that the rise of the cupcake is very much about going back to American national identity in food, which is all about comfort. “People want to think about when they and their country were innocent,” she said.
【小題1】According to the passage, it has been an American tradition that ___________.

A.the family holds a party for children on their birthday
B.a(chǎn) mom cooks a bowl of noodles for her children on their birthday
C.a(chǎn) mom makes a cupcake for her children on their birthday and brings it to the classroom
D.parents go travelling with their children on their birthday
【小題2】Why do doctors ask people to ban cupcakes on children’s birthday?
A.Because they themselves don’t like cupcakes.
B.Because they think cupcakes are not so delicious.
C.Because they believe cupcakes will cause cries of “She got the bigger piece”.
D.Because they believe cupcakes are one of the causes to make children become fat.
【小題3】What cannot be inferred according to Marion Nestle?
A.The cupcake is more democratic than any other desserts in the US.
B.The cupcake is too small to share with others.
C.The sizes of cupcakes are the same so it’s equal to everyone.
D.Cupcakes will lead to child obesity so they should be banned.
【小題4】The underlined word “trendy” in paragraph 7 probably means ________.
A.popular B.gentleC.deliciousD.different
【小題5】Why did the writer mention Hillary Clinton and Ruth Reichl?
A.To arouse the readers’ attention to banning the tradition of making cupcakes.
B.To show that cupcakes are becoming a popular way to show kindness and comfort.
C.To make a comparison between them in order for readers to remember them.
D.To give readers some idea of cupcakes so as to better understand the American culture

科目:高中英語 來源:2011級重慶八中高三(上)第四次月考英語試題 題型:閱讀理解

I really hadn’t meant to yell(吼叫)at them.But that grey afternoon saw it just as my son and daughter were making a terrible mess on the floor in the kitchen.
With a tiresome report to write,I felt bothered at my desk.Suddenly, it occurred to me that my kids were at fault.A voice inside me insisted that I do something quickly.
“OK,you two here.but what an awful thing you are attempting!” shouting angrily, I made for them, while it became evident that the boy wanted no part of me.“Get away from us!” he shouted back,there being expression of support from his sister.
All of a sudden,I found the fault in myself.Quickly I shaped my hands into pincers(螃蟹螯)and crawled towards them,“Crabby(似螃蟹的)Daddy is here Ha,Ha,Ha,he likes to yell at children,and then eat them!” My son continued to keep me away,but now he was laughing and crying at the same time.My mission to repair the damage caused by my yelling seemed to work well.Still,I regretted not having controlled myself first in a right way that my children could do after.
Need I let them know how badly they were acting by blaming? This is a lesson that serves myself.It only shows just how to get rid of something(ill-feelings,responsibility)by blaming others.It’s not my “best self”.
We have to search for our “best self” when with our children.They don’t need perfect parents,but they do need parents who are always trying to get better.Here,I’m reminded of the words of a great thinker,“When a man lives with God,his voice shall be as sweet as the murmur of the brook…” Then,in our lifetime,couldn’t we always speak to our kids in such a sweet voice since,most of us consider them as the most precious in the world? And before we reach this level,what should we do when we come across various difficult cases with our children?  
【小題1】The author couldn’t help yelling at his kids this time probably because______.

A.the weather was so unpleasantB.a(chǎn) Daddy has his right to do so
C.the kids didn’t ask him to join themD.he was tired of his boring work
【小題2】Which of the following made the author aware of his fault?
A.No obvious reason.B.The children’s reaction.
C.His self-control.D.The mess made by the children.
【小題3】According to the passage the author will   in another similar situation.
A.play a crab again like this timeB.a(chǎn)pologize to kids in a sincere way
C.a(chǎn)void blaming kids in a hurryD.beat them up about such things
【小題4】What will the writer go on to write about in the next paragraph(s)?
A.How to behave ourselves properly when kids are at fault.
B.How to blame our children in a more interesting way.
C.How to deal with the terrible mess made by our kids.
D.How to persuade children to do what they are told to.

If you look for a book as a present for a child. You will be spoiled for choice even in a year when there is no new Harry Patten J.K Rowling’s wizard is not alone: the past decade has been a harvest for good children’s books ,which has set off a large quantity of films and in turn led to increased sales of classics such as The Lord of the Rings.
Yet despite that ,reading is increasingly unpopular among children .According to statistics, in 1997 23% said they didn’t like reading at all . In 2003, 35% did . And around 6% of children leave primary school each year unable to read properly.
Maybe the decline is caused by the increasing availability of computer games. Maybe the books boom has affected only the top of the educational pile . Either way , Chancellor Cordon Brown plans to change things for the bottom of the class .In his pre-budget report , he announced the national project of Reading Recovery to help the children struggling most.
Reading Recovery is aimed at six-year-olds ,who receive four months of individual daily half-hour classes with a specially trained teacher . An evaluation earlier this year reported that children on the scheme made 20 months’ progress in just one year, whereas similarly weak readers without special help made just five months’ progress ,and so ended the year even further below the level expected for their age.
International research tends to find that when British children leave primary school they read well ,but read less often for fun than those elsewhere .Reading for fun matters because children who are keen on reading can expect lifelong pleasure and loving books is an excellent indicator of future educational success . According to the OECD, being a regular and enthusiastic reader is of great advantage.
46.Which of the following is true of Paragraph 1?
A.Many children’s books have been adapted from films.
B.Many high-quality children’s books have been published .
C.The sales of classics have led to the popularity of films.
D.The sales of presents for children have increased.
47.Statistics suggested that _______.
A.the number of top students increased with the use of computers
B.a decreasing number of  children showed interest in reading
C.a minority of primacy school children read properly
D.a large percentage of children read regularly
48.What do we know about Reading Recovery?
A.An evaluation of it will be made sometime this year.
B.Weak readers on the project were the most hardworking.
C.It aims to train special teachers to help children with reading.
D.Children on the project showed noticeable progress in reading.
49.Reading for fun is important because book-loving children _________.
A.take greater advantage of the project       B.show the potential to enjoy a long life
C.are likely to succeed in their education.    D.would make excellent future researchers
50.The aim of this text would probably be _________.
A.to overcome primary school pupils reading difficulty.
B.to encourage the publication of more children’s books
C.to remind children of the importance of reading for fun
D.to introduce a way to improve early childhood reading
