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(好奇). Firstly, listen to their questions. I once visited a chlassroom of seven-year-olds to talk about science as a job. The children asked me “textbook questions” about schooling, salary(薪水) and whether I liked my job. When I finished answering, we sat facing one another in silence. 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(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, dults 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(符合逻辑的), 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(行为). 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(目标) 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(放大镜), and they’ll understand why you want them to wash before dinner. Rather than saying that water evaporates(蒸发), set a pot of water to boil and let them watch the water level drop.
57. According to the passage, children are natural scientists, and to raise their interest, the most important thing for adults to do is ________.
A. to let them see 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
58. In the last sentece of the first paragraph, the word “lists” could best be replaced by “________”.
A. any questions                            B. any problems
C. questions from textbooks                   D. any number of questions
59. 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
60. 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(背诵) facts

An oasis (绿洲) is an island of life in an ocean of temperature extremes.Any oasis always contains one or more springs Oases make it possible to survive through the desert.In large deserts such as the Sahara.towns are located around sources of water such as oases and rivers.
What causes an oasis? An oasis is actually a spot in the desert where the altitude is low enough that the water table is fight below the surface,resulting in the presence of springs.Even in a desert, it rains occasionally,and this produces a water table just above the bedrock,usually several hundred feet below the surface.Sand is very porous (可渗透的),so most water runs right
through it and down to the bedrock.
Deserts consist of many millions of tons of sand.There is only one natural force capable of moving it in noticeable amounts:the wind.Although,in an average dust storm,ten cubic feet of air only holds about an ounce of sand,a cubic mile of air can move about 4,600 tons of it,leading to erosion (侵蚀).A severe storm is capable of moving as much as 100 million tons of sand and dust.
In certain areas where large quantities of sand are moved by storms,erosion digs all the way down to the water table,putting it just beneath the surface Seeds planted in the ground there are capable of extending roots into the moist land,producing an oasis.
Sometimes.the oasis produced by the wind can be very large when vast tracts of desert are wiped clean by storms.The great Kharga oasis in the Sahara,for example,is over 100 miles long and 12 to 50 miles in width. The oasis was produced when erosion caused the edges of the hollow places to sink down to the water table.    
63.What does “it” in Paragraph 4 refer to_______.
A.erosion        B.water table          C.sand                      D.storm
64.How many conditions of the oasis formation are mentioned in the passage without considering
The wind and seeds?
A.3                B.4                        C.5                           D.6
65.We can infer from the passage ________.
A.there is at least one spring on an oasis
B.the bedrock is usually just right below the surface
C.the great Kharga oasis is the biggest oasis in the world
D.the great Kharga oasis is at a low altitude
66.In the last paragraph,the author mentions the great Kharga oasis as an example to_______.
A.introduce the great oasis to the readers
B.tell how the oasis was produced by rain
C.show the oasis produced by the wind can be very large
D.tell it’s easy to form oases in the desert after storms

The centerpiece of curling(冰壶)is the curling stone, which has been called a “geometrical masterpiece of tooled geology (地质). ” Kays of Scotland has been making curling stones since 1851, when William Kay and his sons Andrew and Thomas set up a workshop in Mauchline, Ayrshire , in southwest Scotland. Kays is still owned by the relatives of the founder, and today it is the only curling stone maker left in Scotland.
Used in a highly competitive sport, the curling stones are made to exact standards. First, stones are sliced and then into round “cheeses”. Finally , the cheeses are shaped and polished into curling stones in a series of precise steps.
Each stone must weigh 44 pounds. Each must have a maximum diameter (直径) of 36 inches. Polishing is done by hand on a wheel using water, diamond-talcum power, and felt. Finishing the stone’s “running edge” is done entirely by hand with a special kind of paper and a digital measure and magnifying glass (放大镜). Lastly, a handle is fitted into holes on the top of the stone. Stones are computer-matched into pairs. Sixteen stones -8pairs-are needed for a game, and since curling game field usually have 6 lanes, each game field needs 96 matched stones!
Kays is a small firm, employing than ten skilled workers. Master craftsman and co-owner James Wyllie is skilled at all phases of curling stone making and is also an enthusiastic curler, as well as active member of Mauchline’s Burns Club, which meets regularly to honor well-known Mauchline residents.
59.What IS true about Kays?
A.It is a family business.            B.It’s a brand of curling stones.
C.It’s a place in Scotland.                     D.It’s the name of a curling stone dealer.
60.How many curling stones are needed for two games happening at the same time?
A.8.                           B.16.                  C.32.               D.96.
61.Which of the following shows the right process of making a curling stone?
A. Slicing—shaping—polishing. 
B.Weighing—measuring—polishing.
C. Cutting—running—edging—computer—matching
D. Cutting—measuring——shaping——polishing

A
Watching television more than two hours a day early in life can lead to attention problems later in adolescence, according to a study released on Tuesday.
The roughly 40 percent increase in attention problems among heavy TV viewers was observed in both boys and girls. The link was established by a long-term study of the habits and behaviors of more than 1,000 children born in Dunedin, New Zealand, between April 1972 and March 1973.
The children aged 5 to 11 watched an average of 2.05 hours of weekday television. From age 13 to 15, time spent in front of the tube rose to an average of 3.1 hours a day.
"Those who watched more than two hours, and particularly those who watched more than three hours, of television per day during childhood had above-average symptoms of attention problems in adolescence," Carl Landhuis of the University of Otago in Dunedin wrote in his report, published in the journal Pediatrics.
Young children who watched a lot of television were more likely to continue the habit as they got older, but even if they did not the damage was done, the report said.
"This suggests that the effects of childhood viewing on attention may be long lasting," Landhuis wrote.
Landhuis offered several possible explanations for the association.
One was that the rapid scene changes common to many TV programs may over stimulate(刺激)the developing brain of a young child, and could make reality seem boring by comparison. "Hence, children who watch a lot of television may become less tolerant of slower-paced and more mundane tasks, such as school work," he wrote.
It was also possible that TV viewing may supplant other activities that promote concentration, such as reading, games, sports and play, he said.
Previous studies have linked the sedentary固定不动的)habit of TV watching among children to obesity and diabetes, and another study in the same journal cited the poor nutritional content of the overwhelming majority of food products advertised on the top-rated US. children"s television shows.
Up to 98 percent of the TV ads promoting food products that were directed at children aged 2 through 11 "were high in either fat, sugar, or sodium," wrote Lisa Powell of the University of Illinois in Chicago.

A. watching TV can cause all kinds of diseases for children
B. TV sets have played an important part in our daily lives
C. Watching TV over 2 hours a day early in life can cause attention problems later in adolescence
D. watching TV has side effects on children’s future
57. People used to think that _________.
A. watching TV more than 2 hours every day did good to children’s health
B. the sedentary habit of TV watching among children could easily lead to obesity and diabetes
C. the children wasn’t patient with their homework because of watching TV too much
D. it was very important for children to watching TV early in life
58. The underlined word “Hence” means _________.
A. In that case    B. And yet    C. On the contrary    D. For this reason
59. In Landhuis’ opinion, _________.
A. attention problems caused by watching TV during childhood may be hard to get rid of
B. how to develop children’s attention problems is a lasting problem
C. the key of settling attention problems is not watching TV too much

This election had many firsts and many stories that will be told for generations. But one that"s on my mind tonight’s about a woman who cast her ballot in Atlanta. She is a lot like the millions of others who stood in line to make their voice heard in this election, except for one thing: Ann Nixon Cooper is 106 years old.
She was born just a generation past slavery; a time when there were no cars on the road or planes in the sky; when someone like her couldn"t vote for two reasons, because she was a woman and because of the color of her skin.
And tonight, I think about all that she"s seen throughout her century in America: the heartache and the hope; the struggle and the progress; the times we were told that we can"t, and the people who pressed on with that American creed: Yes we can.
At a time when women"s voices were silenced and their hopes dismissed, she lived to see them stand up and speak out and reach for the ballot. Yes we can.
When there was despair in the Dust Bowl and depression across the land, she saw a nation conquer fear itself with a New Deal, new jobs, a new sense of common purpose. Yes we can.
When the bombs fell on our harbor and tyranny threatened the world, she was there to witness a generation rise to greatness and a democracy was saved. Yes we can.
She was there for the buses in Montgomery, the hoses in Birmingham, a bridge in Selma, and a preacher from Atlanta who told a people that "we shall overcome." Yes we can.
A man touched down on the moon, a wall came down in Berlin, a world was connected by our own science and imagination. And this year, in this election, she touched her finger to a screen, and cast her vote, because after 106 years in America, through the best of times and the darkest of hours, she knows how America can change. Yes we can.
America, we have come so far. We have seen so much. But there’s so much more to do. So tonight, let us ask ourselves, if our children should live to see the next century; if my daughters should be so lucky to live as long as Ann Nixon Cooper, what change will they see? What progress will we have made? 
(From Obama’s victory speech, 2008 )
