26、 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 high 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, presently the size and thickness of a penny, intended to power various micro systems(MNEMS). 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 semi conduct or 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(晶体结构)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 battery could be thinner than the thickness of human hair.
【1】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.
【2】Jae Kwon gave examples in Paragraph 4 _____.
A. to show chemical batteries are widely applied.
B. to introduce nuclear batteries can be safely used.
C. to describe a nuclcar powered system
D. to introduce various energy sources.
【3】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
【4】The text is most probably a _____.
A. science news report B. book review
C. newspaper ad D. science fiction story
27、 A comparison of nesting data recorded in the early 1900s with similar data today for more than 200 species of California birds shows that over all they are breeding(繁殖)5 to 12 days earlier than they did 75 to 100 years ago.
Earlier studies found that many but not all birds in California’s mountains are moving north or to higher altitude to find cooler temperatures in the face of global warming.
The shift to earlier breeding that we detected allows birds to nest at similar temperatures as they did a century ago, and helps explain why half the bird species in the mountainous areas of California did not need to shift upward in altitude in response to climate warming over the past century, said Steven Beissinger, a UC Berkeley professor of environmental sciences.
Early spring arrivals have long been noted by the public and reported by scientists, but the assumption has been that the birds are tracking resources, primarily food: with warming temperatures, plants produce leaves and seeds earlier, and insects appear earlier.
The new study spotlights another major reason: by nesting a week earlier, birds produce eggs and young at a temperature about 1 degree Celsius lower than if they nested at the normal time in the same place. This exactly counterbalances the approximately 1 degree Celsius increase in global temperatures over the past century.
“By nesting a week or 10 days earlier, birds are avoiding some of the negative effects of climate warming,”Beissinger said.” the good news is that there may be more flexibility for species to respond to climate change than we thought, and not all species may need to move farther north or to higher altitudes, “he added. “But we don't know yet whether staying in place and shifting schedules earlier is a permanent solution, or only provides temporary relief from the 2 degree Celsius rise in temperatures forecast to occur.”
Birds may find, for example, that the window of good temperatures for breeding becomes shorter, which may limit the opportunity to re-nest if they fail the first time. Larger species that have a longer nesting period might not have an enough time to complete their nests before it starts to become too warm, he said.
【1】To fight against the global warming, earlier studies found that _______.

28、 It was early in the spring about 15 years ago when I was a young police reporter, driving to a scene I didn't want to see. A man had accidentally backed his pickup truck over his baby granddaughter in the driveway of the family home.
As I arrived. I saw a while-haired man in cotton work clothes standing near a truck, looking totally confused, he was trying to answer the reporters 'questions. Mostly he was only moving his lips, blinking and choking up.
After a while the reporters gave up oil him mid fo1lowed the police into the small white house. A few minutes later, with all the details in my notebook and a three-by-five photo in my jacket pocket I went toward the kitchen where die police had said the body was.
I had brought a camera in with me. Entering the kitchen, I came upon this scene.
On a table lay the tiny body, wrapped in a clear white sheet. Somehow the grandfather had managed to stay away from the crowd He was sitting on a chair beside the table, looking helplessly at the dead body. As I watched, the grandfather slowly leaned forward, held the little in his arms and remained still.
In that moment I recognized the makings of a prize-winning news photograph. I raised the camera......
Every element of the picture was perfect I don't know how many seconds I stood there, unable to press that shutter (快门). I fully realized the powerful story-telling value that photo would have, and my professional conscience (良心) told me to lake it. Yet I couldn't make my hand move and break into the poor man’s inner sadness.
At last I lowered the camera and moved away quietly with doubt about my suitability for the journalistic profession (职业). Now, sometimes, as I'm watching news, I remember that day.
I still feel right about what I did.
【1】Why did the author drive to the man's house?
A.To comfort the poor man.
B.To perform a duty.
C.To offer some help.
D.To get a prize-winning photo.
【2】What do we know about the grandfather in the passage?
A.He was deeply sorry for the loss of his granddaughter.
B.He didn't want to answer the reporters' questions.
C.He shared little about the accident with the author
D.He purposely created the scene for the author's photo.
【3】Why did the author give up taking the picture at last?
A.Because he preferred better photos.
B.Because the grandfather noticed him.
C.Because professional training told him not to.
D.Because his conscience told him to do so.
【4】What is the author's purpose in writing the story?
A.To describe a heart-broken scene.
B.To tell one of his experiences.
C.To learn from other photo takers.
D.To persuade people to pity others
29、Geocaching
Common Sense Media says that this expensive but very cool GPS app makes it possible for the whole family to go geocaching, a high-tech treasure hunt game. This app makes it unnecessary to buy a dedicated GPS device. The app taps directly into a database with more than 2 million locations, some within walking distance, and gives you everything you need to find treasures hidden by other enthusiasts.
SkySafari
SkySafari is a powerful mobile planetarium(天象馆)that uses GPS locations to view the night sky. The app comes in multiple versions. The databases, even on the entry-level versions, are large, requiring up to 940 MB of free space depending on the platform. You can learn about astronomy by viewing planets and stars, searching for specific objects of interest or looking at astronomical sightings in that night's sky.
Historypin
Historypin is a great tool to bring families together to share stories. You can learn about the history of any area by searching Historypin's world map by place, time, or subject. Because there are a few different ways to use Historypin's bank of user-contributed knowledge, as well as ways to add content, you can learn how to access and create digital content that's meant to be shared with the general public.
