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 classroom 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’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(符合逻辑的), complete and cre ative 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.
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

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

Batteries can power anything from small sensors to large systems. While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves. University of Missouri (MU) researchers are developing a nuclear energy source that is smaller, lighter and more efficient.
“To provide enough power, we need certain methods with energy density (密度),” said Jae kwon, assistant professor of electrical and computer engineering at MU. “The radioisotope (放射性同位素) battery can provide power density that is much higher than chemical batteries.”
Kwon and his research team have been working on building a small nuclear battery, recently the size and thickness of a penny, intended to power various micro/nano-electromechanical systems (M/NEWS). Although nuclear batteries can cause concerns, Kwon said they are safe.
“People hear the word ‘nuclear’ and think of something very dangerous,” he said. “However, nuclear power sources have already been safely powering a variety of devices, such as pace-makers, space satellites and underwater systems.”
His new idea is not only in the battery’s size, but also in its semiconductor (半导体). Kwon’s battery uses a liquid semiconductor rather than a solid semiconductor.
“The key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure (晶格结构) of the solid semiconductor, ” Kwon said. “By using a liquid semiconductor, we believe we can minimize that problem.”
Together with J. David Robertson, chemistry professor and associate director of the MU Research Reactor, Kwon is working to build and test the battery. In the future, they hope to increase the battery’s power, shrink its size and try with various other materials. Kwon said that the battery could be thinner than the thickness of human hair.
Which of the following is true of Jae Kwon?

A.He teaches chemistry at MU.
B.He developed a chemical battery.
C.He is working on a nuclear energy source.
D.He made a breakthrough in computer engineering.

Jae Kwon gave examples in Paragraph 4 ________.

A.to show chemical batteries are widely applied
B.to indicate nuclear batteries can be safely used
C.to describe a nuclear-powered system
D.to introduce various energy sources.

Liquid semiconductor is used to ________ .

A.get rid of the radioactive waste
B.test the power of nuclear batteries
C.decrease the size of nuclear batteries
D.reduce the damage to lattice structure

According to Jae Kwon, his nuclear battery ________.

A.uses a solid semiconductor B.will soon replace the present ones
C.could be extremely thin D.has passed the final test

The text is most probably a ________.

A.science news report B.book review
C.newspaper ad D.science fiction story

Christopher Thomas, 27, was a writer by night and a teacher by day when he noticed he was always tired and was losing weight fast. Diagnosed with diabetes (糖尿病), Thomas would need to inject himself with insulin (胰岛素) three times a day for the rest of his life or risk nerve damage, blindness and even death. And if that weren't bad enough, he had no health insurance.
After a month of feeling upset, Thomas decided he'd better find a way to fight back. He left Canton, Michigan for New York, got a job waiting tables, nicknamed himself the Diabetic Rockstar, and created diabeticrockstar.com, a free online community for diabetics and their loved ones — a place where over 1,100 people share personal stories, information, and resources.
Jason Swencki’s son, Kody, was diagnosed with diabetes at six. Father and son visit the online children's forums(论坛) together most evenings. "Kody gets so excited, writing to kids from all over," says Swencki, one of the site's volunteers. "They know what he's going through, so he doesn't feel alone."
Kody is anything but alone: Diabetes is now the seventh leading cause of death in the United States, with 24 million diagnosed cases. And more people are being diagnosed at younger ages.
These days, Thomas's main focus is his charity(慈善机构), Fight It, which provides medicines and supplies to people —225 to date— who can't afford a diabetic's huge expenses. Fight-it.org has raised about $23,000 — in products and in cash. In May, Thomas will hold the first annual Diabetic Rockstar Festival in the Caribbean.
Even with a staff of 22 volunteers, Thomas often devotes up to 50 hours a week to his cause, while still doing his full-time job waiting tables. "Of the diabetes charities out there, most are putting money into finding a cure," says Bentley Gubar, one of Rockstar's original members. "But Christopher is the only person I know saying people need help now."
Which of the following is true of Christopher Thomas?

A.He needs to go to the doctor every day.
B.He studies the leading cause of diabetes
C.He has a positive attitude to this disease.
D.He encourages diabetics by writing articles.

Diabeitcrockstar.com was created for _________.

A.diabetics to communicate B.volunteers to find jobs
C.children to amuse themselves D.rock stars to share resources.

According to the text, Kody ______.

A.feel lonely because of his illness
B.benefits from diabeticrockstar.com
C.helps create the online kid’s forums
D.writes children’s stories online

What can we learn about Fight It?

A.It helps the diabetics in financial difficulties.
B.It organizes parties for volunteer once a year.
C.It offers less expensive medicine to diabetics.
D.It owns a well-known medical website.

The last paragraph suggests that Thomas ______.

A.works full-time in a diabetes charity
B.employs 22 people for his website
C.helps diabetics in his own way
D.ties to find a cure for diabetes

There were smiling children all the way. Charily they knew at what time the train passed their homes and they made it their business to stand along the railway, wave to complete strangers and cheer them up as they rushed towards Penang. Often whole families stood outside their homes and waved and smiled as if those on the trains were their favorite relatives. This is the simple village people of Malaysia. I was moved.
I had always traveled to Malaysia by plane or car, so this was the first time I was on a train. I did not particularly relish the long train journey and had brought along a dozen magazines to read and reread. I looked about the train. There was not one familiar face. I sighed and sat down to read my Economics.
It was not long before the train was across the Causeway and in Malaysia. Johore Baru was just another city like Singapore, so I was tired of looking at the crowds of people as they hurried past. As we went beyond the city, I watched the straight rows of rubber trees and miles and miles of green. Then the first village came into sight. Immediately I came alive; I decided to wave hack.
From then on my journey became interesting. I threw my magazines into the waste basket and decided to join in Malaysian life. Then everything came alive. The mountains seemed to speak to me. Even the trees were smiling. I stared at everything as if I was looking at it for the first time.
The day passed fast and I even forgot to have my lunch until I felt hungry. I looked at my watch and was surprised that it was 3:00 pm. Soon the train pulled up at Butterworth. I looked at the people all around me. They all looked beautiful. When my uncle arrived with a smile, I threw my arms around him to give him a warm hug (拥抱). I had never done this before. He seemed surprised and then his weather-beaten face warmed up with a huge smile. We walked arm in arm to his car.
I looked forward to the return journey.
The author expected the train trip to be ________.

A.adventurous B.pleasant C.exciting D.dull

What did the author remember most fondly of her train trip?

A.The friendly country people. B.The mountains along the way.
C.The crowds of people in the streets. D.The simple lunch served on the train.

Which of the following words can best take the place of the word “relish” in the second paragraph?

A.choose B.enjoy C.prepare for D.carry on

Where was the writer going?

A.Johore Baru. B.The Causeway. C.Butterworth. D.Singapore.

What can we learn from the story?

A.Comfort in traveling by train. B.Pleasure of living in the country.
C.Reading gives people delight. D.Smiles brighten people up.

I stepped into my hotel room to a pleasant surprise. Lots of room surrounded an inviting king-size bed, with armchairs nearby resting against sliding glass doors that opened onto a private yard. A small dining table sat next to a kitchen with a refrigerator and coffee machine. "Wow," I thought to myself. "Nice place."
I love hotels. I love to enter a clean room, hang my clothes and gaze out the window, walk out in the morning and when I return, someone else will have made the bed. I like in-room dining and the way they greet you so professionally. "Nice to have you with us again, Mr. Goldsborough." Very cool.
The problem is that unless Alison travels with me, I never sleep well in hotels. I miss my family, even though Linus and Camille, at ages 4 and almost 2, find a way to interrupt even the best night's sleep at home.
I'm deeply troubled by the number of parents who wake up too late with the realization:
"My children grew up too fast. In the busy career and corporate rat race(剧烈竞争), I missed their childhood.” What they fail to say but too often think causes me even more pain: "...and I barely even know them."
A hundred years from now, no one will remember the size of your bank account, the car you drove or the size of your house. The world might differ greatly however, based on your impact in the life of a small child. If you pay attention to your significant others, make the choice to put them first.
Think of one specific action that you can take, and take it. Then think of another one and take that, too. Challenge yourself to find new ways to express your appreciation and love on a daily basis. It will pay off ten-fold(十倍)at home.

For most students, school is over and summer fun is here. Even kids who are going to summer school don't need to be cooped up indoors during these bright sunny days. Why? Thanks to technology, many kids now have the option of attending "virtual" summer schools online.
These "virtual" classes are not new. Many colleges and universities offer online courses where the students never meet; they correspond with their teachers and classmates on the web. Even some traditional schools add to daily classes with internet-based assignments and feedback.
There are a lot of benefits to online schooling, and that's why public schools have started participating in this non-traditional type of education. Instead of students riding the bus, going to class, eating lunch at school, and going home in the early afternoon, they can now log on(登录)at any time of day or night and learn. This flexible online option requires just as much work and participation as normal summer school. However, the timing is different.
Online summer school is not for all students, just like it isn’t for all adults. The student needs to be an excellent reader in order to obtain as much information as possible from the lectures. In addition, students must understand computers and be self motivated(激发)in order to complete the class successfully.
If the students meet these requirements, then online summer school has many advantages. Written lectures can be read and reread until the student understands them. The students can email each other and the teacher if they need help. Students who participate in online summer school often earn higher grades because the teachers can answer more questions without slowing down the entire class progress. And because of this new technology, summer school students can still go to the beach, travel around the world, and take family vacations!
Online schooling has the following advantages and benefits EXCEPT ____.

A.Students needn’t have as much work or participation as in traditional schools.
B.Students don’t have to go to school in crowded buses.
C.Students can have more time to understand the lessons.
D.Teachers and students have more time to arrange their own things flexibly.

What does the underlined word “option” probably mean?

A.chance of expressing opinion B.chance of expressing wishes
C.right of demanding D.right of choosing

Online summer school is not suitable for ____.

A.adults or children who are too old
B.students who are poor in reading
C.those who don’t master good computer technology
D.students who can’t finish homework on their own

Which of the following people is most supposed to choose online schooling?

A.A child in the kindergarten. B.A primary school student.
C.A government office clerk. D.A child whose parents are working.
