Children start out as scientists, eager to look into the world around them. them enjoy science can be ; there's no need for scientific terms or expensive lab equipment. You only have to share your children's interests.
Firstly, listen to their questions. I once a classroom of seven-year-olds to talk about science as a job. The children asked me "textbook questions" about schooling, salary and my job. When I answering, I said, " we're finished with your lists, do you have questions of your own about science ?" After a long , a boy his hand, "Have you ever seen a grasshopper（蚱蜢） ？When I try eating leaves like that, I get a stomachache. Why ?" This began a set of questions that nearly two hours.
Secondly, give them time to think. After asking a question, teachers often wait only one or less for an answer, no time for a child to think. When teachers their "wait time" to three seconds or more, children usually give better answers.
Thirdly, watch your language. When children are having a science discussion, don't jump in with "That's right" or "Very good" because these may make the children think that discussion is over. , keep things going by saying, "I'd never thought of it that way before", or coming up with more questions or ideas.
Never a child to "think". It doesn't make sense, because children are always thinking without your telling them to. What's more, this can turn a conversation a performance.
, show in stead of telling. Let children look at their fingers through a magnifying glass（放大镜）, they'll understand why you want them to before dinner. Rather than say that water evaporates（蒸发）, set a pot of water to boil and let them watch the water level .

Henry Manley, boss of Mr. Smith, was the 55of a small company 56computers. The company was in 57trouble, because among other reasons, the Japanese were selling such things at very 58prices.

too long ago ,an incident that happened at Walt Disney touched me greatly. A guest 36 out of our Polynesian Village resort（度假胜地）at Walt Disney was asked how she 37 her visit .She told the front-desk clerk she had had a (n) 38 vacation ,but was heartbroken about 39 several rolls of Kodak color film she had not yet 40 .At that moment she was particularly 41___over the loss of the pictures she had shot at our Polynesian Luau , 42 this was a memory she especially treasured.
Now ,please understand that we have no written service rules 43 lost photos in the park. 44 ,the clerk at the front desk45 Disney’s idea of caring for our46 . She asked the woman to leav
e her a couple rolls of47 film ,promising she would take care of the rest of our show at Polynesian Luau.
Two weeks later the guest received a 48 at her home .In it were photos of all the actors of our show, 49 signed by each performer. There were also 50 of the public procession（游行队伍）and fireworks in the park ,taken by the front-desk clerk in her
own 51____ after work. I happened to know this 52 because this guest wrote us a letter .She said that 53in her life had she received such good service from any business.
Excellent 54does not come from policy (政策性的)handbooks .It comes from people who
55 — and from a culture that encourages and models that attitude.

As a mother, I have been blessed. I have a nice, smart, good-looking son named Alan. About a month ago, there was an assembly (集会) about seat belt safety 36 at Alan’s high school. One of the presenters in this program, Kathy Hezlep, had 37 her son in a horrible car crash the year before.
When Kathy was 38 asked to speak at this assembly, she was reluctant (不情愿的). Her son’s 39 had been extremely hard on her. She often felt helpless and discouraged, and she wasn’t sure how she could 40 a difference by speaking to this group.
But at last she 41 to talk to the students in the school. Kathy spoke about how 42 it had been since the loss of her son. She spoke 43 from her heart and 44 son took her words straight into his heart.
One day, the worst nightmare came. The 45 told me my son had been driving down a curving road and lost 46 of the car. When I was taken to the scene of the 47 and saw the broken car, I felt physically 48 . I couldn’t 49 three kids had walked away from that car 50 .
When I got to the hospital, I talked to Alan about the accident. He told me that 51 of the kids had been 52 their seat belts when he started the car. But Kathy’s words about her terrible loss had 53 him so deeply that he 54 that everyone put on their shoulder and lap belts before he would leave. That is 55 had saved their lives.

Water and its importance to human life were the centre of the world’s attention last week. March 22 was World Water Day and 36 the theme “Water for Life”.
There are more than one billion people in the world who live without 37drinking water. The United Nations 38 to cut this number in half by 2015.
Solving such a big problem seems like a(n) 39challenge. But everyone, 40 teenagers, can do something to help. A teenage girl in the US has set an example to the 41of her age around the world.
Rene Haggerty, 13, was awarded the 2004 Gloria Barron Prize for her work— 42 discarded(废弃的) batteries（电池）which pollute water.
In 2003, Haggerty went on a field trip to the Great Lakes Science Centre in Ohio. There she saw an exhibit about how 43in old batteries harm the water of Lake Erie.
Haggerty learnt that 44the batteries was an easy solution. “I think everybody can do it, because everyone 45 batteries, and it can make a big difference.” With these words, she began to 46 awareness in her area.
She 47her county government and school board. She got permission to start a recycling programme in schools 48 the public library, hospital, and churches. With the help from her family, friends and local waste-management 49, she gathered containers, arranged transportation, and made a(n) 50video.
Over the past two years, she collected four tons of batteries and drew the attention of officials, who were in charge of a battery recycling programme but had made 51 progress.
When asked 52 she feels like a hero, Haggerty is quite __53. “Not really. Well, maybe for the fish I saved!”
Every year the Gloria Barron Prize is 54to young Americans aged 8 to 18 who have shown leadership and courage in 55 the public and the planet. Each year ten winners receive US $ 2,000 each, to help with their education costs or their public service work.
