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. 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 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 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. 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.
【小题1】According to the passage, children are natural scientist, and to raise their interest, the most important thing for adults to do is______________.

How would you like an easy way to earn 2,500 dollars? All you have to do is to sit around and wait for your meals．There’s catch, however．You have to stay in a chicken cage with a stranger for a whole week．There are no books or television or radio for amusement．You can’t leave until the week is up．And a camera will be recording your every move．
Two people actually took the job．The idea came from Rob Thompson, a video artist．He wanted to make a film about the way animals are treated．His goal was to raise people’s awareness of the living conditions of animals that are raised for food．He decided to pay $ 5000 out of his own savings to two people who were willing to lie like chicken for a week．
To Rob’s surprise, quite a few people answered his advertisement．He had interviews and selected Eric, a 24-year-old restaurant worker, and Pam, a 27-year-old chemist．The plan was for them to spend seven days together in a chicken cage that was six feet long and three feet wide．A camera would record their experience, which would take place in an art museum．
The week was long and difficult．They slept on a hard wooden floor．They couldn’t stand up without banging（重击）their heads．They ate vegetarian mash（土豆泥）and drank water from a garden hosepipe（水龙头软管）．Their only privacy was a toilet surrounded by a curtain．There were no sinks, mirrors, or toothbrushes in the cage．Their only inspiration was the two framed checks that hung on the wall outside the cage．Visitors who came here were warned, “Do not food the humans．”
Finally it was over, Pam and Eric emerged from their cage．They had survived the week, and they each had a $2,500 check in their hands．When Rob Thompson opened the cage, Eric came out, changed into clean clothes, and ate a chocolate bar right away．“It’s great to be able to stand up,” he said．Pam just changed her clothes and left．After a week of visitors and reporters watching her, she didn’t want to talk to anyone．

Homemade Ice Cream in a Bag
Difficulty: Very Easy
Average User Rating:★★★★☆(4.3/5)
Milk can become homemade ice cream in five minutes by using a bag! This homemade, creamy treat is a summertime delight for your kids and you alike.
What you’ll need:
1 tablespoon of sugar; 1/2 cup of milk; 1/4 teaspoon of vanilla (香草香精); 6 tablespoons of rock salt; 1 small-sized plastic food storage bag; 1 gallon-sized plastic food storage bag; ice cubes.
How to make it:
l Fill the large bag half full of ice, and add the rock salt. Seal the bag.
l Put milk, vanilla, and sugar into the small bag, and seal it.
l Place the small bag inside the large one, and seal it again carefully.
l Shake until the mixture turns into ice cream, which takes about five minutes.
l Wipe the top of the small bag, and then open it carefully. Enjoy!
Tips:
1/2 cup of milk will make about one spoon of ice cream, so double the recipe if you want more. But don’t increase the amount more than that—a large amount might be too big for kids to pick up because the ice itself is heavy.
Here is another version of the homemade ice cream recipe from another parent!
These are the homemade ice cream ingredients:
1/4 teaspoon of vanilla butter and nuts; 1 tablespoon of sugar; 1/2 cup of milk.
These are the other supplies:
Plastic sandwich bag; 12 salt pellets; 1 dish of ice; large plastic bag.
Put the ice cream ingredients in the small bag, and then put the bag, salt and ice in the big bag. Hold the bag shut and move it around on the floor for about 5 minutes.
When I made ice cream at home last time, although the salt pellets didn’t really dissolve (溶解) that well, I still got ice cream. It was not smooth ice cream, probably because of the low-fat milk. It was incredible that it could be ready in 5 minutes (not counting preparing the ingredients)
Next, I changed the recipe, using a tablespoon of cocoa, a tablespoon of sugar, and a cup of milk. It was a bit too chocolaty, but good!
【小题1】The underlined “that” in “Tips” section refers to ____.

One would have to be a fool to overlook (忽视)the importance of using positive(积极的) thinking for you rather than allowing negative thinking to work against you. In recent years, research in psychopharmacology (精神药理学) has proved what many people have known over the centuries: a positive attitude is good for you, good for your health, good for your wealth, good for everything. Researchers found that a positive attitude produces a specific chemical reaction which makes people feel better, while negative thinking results in a decline of hormone (荷尔蒙) and shuts down the immune (免疫的) system. This leads to illness and depression. Positive thoughts will make you feel better. Even if you must begin by literally forcing yourself to be positive (faking it, so to speak), it will become contagious (会传播的) and the positive thoughts will generate nice little chemicals and good feelings which will reinforce the positive thoughts.
For example, if you force yourself to smile or laugh, even when you don't feel like smiling or laughing, if you keep at it for a few minutes, you will soon feel like it. Feelings can generate (导致)thoughts, but thoughts can also generate feelings. Control your thoughts and you can control your feelings. Positive thinking is important in all aspects of our lives. There is probably no single factor more important in determining your success in achieving your career objectives than your own attitude.
It's often been said that in the land of the blind, the one-eyed man is king. And in the office of militant (好战) negativism, the positive workers shine like gold. You cannot control external events, but you can learn to control your reaction to those events and thereby have a positive attitude and be happy. This vital key to success is totally within your control. Use it.
