When I was a very young children, my father created a regular practice I remember well years late. Every time he arrived home at end of the day ,we'd greet her at the door. He would ask who we was and pretend not to knowing us. Then he and my mother would have had a drink while she prepared dinner and they would talk about his day and hers. While they chat, my father would lift my sister and me up to sit in the top of the fridge. It was both excited and frightening to be up there！My sister and I thought he was so cool for putting us there.
Are you facing a situation that looks impossible to fix?
In 1969,the pollution was terrible along the Cuyahoga River Cleveland, Ohio. It1.(be) unimaginable that it could ever be cleaned up. The river was so polluted that it2.(actual) caught fire and burned. Now, years later, this river is one of3.most outstanding（杰出的）examples of environmental cleanup.
But the river wasn’t changed in a few days4.even a few months. It took years of work 5.(reduce) the industrial pollution and clean the water. Finally, that hard work paid off and now the water in the river is6.(clean) than ever.
Maybe you are facing an impossible situation. Maybe you leave a habit7.is driving your family crazy. Possibly you drink too much or don’t know how to control your credit card use. When you face such an impossible situation, don’t you want a quick fix and something to change immediately?
While there are8.(amaze) stories of instant transformation, for most of us the9.(change) are gradual and require a lot of effort and work, like cleaning up a polluted river. Just be 10.(patience).
I had never known a Christmas when we could ask for a special gift and actually expect to get it. The Great Depression (大萧条) of the 1930s really___ our farming community of Belleville, Michigan. Then came 1940; I was 7 years old and my brother, David, was 8. That year my father got a(n)___ job, and David and I were asked to choose the one ___we most wanted to get that year.

On David’s face was a look of both delight and____. The bike was secondhand, which David didn’t___ , but it was a girls’ bike. Boys did not ride girls’ bikes. Personally, I wouldn’t have ___if it had come with pink bows on it – it was still a bicycle.
David and I had been learning to ride on bicycles____from friends in the neighborhood. I was not as____a rider as he was, but I could____to get from point A to point B.
David was very____, letting me ride his new wheels often. He even____out a way to tie our Radio Flyer wagon to the bike so he could pull me and other kids up and down our road.

As free as they make us, mobile phones still need to stay close to a power source. Soon that may change with "green" power.
Three Chilean students got the idea for a plant-powered device(装置) to charge（使……充电） their cellphones, while sitting in their school's outdoor courtyard during a break from exams, with dead mobile phones. Then, one of them had an "aha" moment.
“It occurred to Camila to say about plants,”said inventor Evelyn Aravena. “‘Why don't you have a socket, if there are so many plants? ’After that, we thought, ‘why don't they have a charging outlet（插座）? Because there are so many plants and living things that have the potential to produce energy, why not?’”
Their invention—a small biological circuit called E-Kaia—uses the energy plants to produce during photosynthesis(光合作用). A plant uses only a small part of that energy and the rest goes into the soil, and that's where the E-Kaia collects it. The device plugs into the ground and then into your phone.
"It's the most amazing project I've ever seen in my life, plain and simple. They brought this original model, and it worked — and that's when it all changed, at least from my personal point of view and I began to support them." said Mauricio Cifuentes.
The device solved two problems for the engineering students — they needed an idea for a class project, and an outlet to plug in their phones.
"Looking for a place to charge the notebook, which had no power, and the mobile phones, we weren't able to find anything because all the other students were in the same state of madness trying to find a place to charge their devices," said Aravena.
But plants are everywhere, and the bio－circuit makes good use of their excess(过多的) power.
The E-Kaia doesn't carry much charge but it's powerful enough to completely recharge a mobile phone in less than two hours.
The student inventors have applied for patents（专利） on their technology, and expect the E-Kaia to go on sale in the near future.
1.How could the students get the "green" power idea?
A. By carrying out an experiment.
B. Just from an occasional thought.
C. With the support of their professors.
D. Inspired by the information in a science book.
2.The device collects power by using _____________.
A. photosynthesis
B. a small biological circuit
C. energy plants
D. the electricity stored in the device
3.What can we learn from what Mauricio Cifuentes said?
A. He intended to buy the patent.
B. He invented the original device.
C. He showed great interest in the device.
D. He wanted to produce the device in large numbers.
4.What might be the best title for the passage?
A. A New Device to Change the World
B. Green Power - A New and Potential Source
C. Chilean Students Find A Green Way to Charge Phones
D. A New Device Invented by Chilean Students Will Be on Sale
On her first morning in America last summer, my daughter went out to explore her new neighborhood alone, without even telling my wife or me. Of course we were worried; we had just moved from Berlin, and she was just 8. But when she came home, we realized we had no reason to panic. Beaming with pride, she told us how she had discovered the little park around the corner, and had made friends with a few local dog owners.
When this story comes up in conversations with American friends, we usually meet with polite disbelief. Most are horrified by the idea that their children might roam(闲逛) around without adult supervision(监管).
A study by the University of California has found that American kids spend 90 percent of their free time at home, often in front of the TV or playing video games. Such narrowing of children's world has happened across the developed world. But German parents are generally much more accepting of letting children take some risks.
“We are depriving(剥夺) them of opportunities to learn how to take control of their own lives,” writes Peter Gray, a research professor at Boston College. He argues that this increases the chance that they will suffer from anxiety, depression, and various other mental disorders, which have gone up dramatically in recent decades(十年).
I am no psychologist like Professor Gray, but I know I won't be around forever to protect my girls from the challenges life holds in store for them. And by giving kids more control over their lives, they learn to have more confidence in their own abilities.
1.Hearing the author's daughter exploring the new neighborhood alone, his American friends feel________.
A. worried B. proud
C. doubtful D. terrified
2.We can conclude from Paragraph 3 that ________.
A. American kids enjoy playing at home
B. German parents are less protective than American parents
C. German kids like taking risks more than American kids
D. American parents don't limit their children's activities in their leisure time
3.It's implied from Professor Gray's words that ________.
A. parents should always be around their children to protect them from risks
B. more and more parents suffer from mental problems
C. children are having more opportunities to take control of their lives
D. giving children more freedom is beneficial to their mental development
4.Which of the following words can best describe the author's parenting?
A. Open-minded. B. Irresponsible.
C. Careless. D. Protective.
