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 eng ineering 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/nanoelectromechanical systems(M/NEMS). 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 belie ve 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 s ize and try with various other materials. Kwon said that the 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 appliedB. to indicate nuclear batteries can be safely usedC. to describe a nuclear-powered systemD. to introduce various energy sources3. Liquid semiconductor is used to .A. get rid of the radioactive wasteB. test the power of nuclear batteriesC. decrease the size of nuclear batteriesD. reduce the damage to lattice structure4. According to Jae Kwon, his nuclear battery .A. uses a solid semiconductorB. will soon replace the present onesC. could be extremely thinD. has passed the final test5. The text is most probably a .A. science news reportB. book reviewC. newspaper adD. science fiction story【参考答案】1--5 、CBDCA科普学问类阅读下列四篇短文，从每小题后所给的A,B,C或D四个选项中，选出最佳选项。

2. 柔声细语，保持你的声音低沉，每当你在别人面前。

你要体谅，避免打扰你周围的人。

6. 如果一定要和它可能会打扰别人，用无声振铃模式和移动谈。

如果您必须呼叫时，可以把你的设备上沉默环或震动，稍后再检查您的来电或语音信箱。

如果你必须采取一个电话，无论你身在何处，移动到一个私人的空间，你可以静静地。

如果你与一组，只需原谅自己了几分钟：“对不起，我需要把这个调用。

我马上回来。

“保持通话尽量简短。

8. 不要文本在课堂上或在你的工作会议上，重要的是要确保你给那些在你面前全部注意力。

课堂或会议时发短信分心他人，但它是你分心，最终导致你错过了潜在的重大和关键的信息。

9. 私人信息可以被转发，这样做不是文本。

不要文本什么保密的，私人的，或潜在的尴尬。

我想拥有一部手机作文作文英语

我想拥有一部手机作文作文英语Having a cell phone is a common desire for many peoplein today's society. It has become an essential tool for communication, entertainment, and productivity. The convenience and connectivity that a cell phone provideshave made it nearly indispensable in our daily lives. However, there are also downsides to owning a cell phone, including potential addiction, privacy concerns, and negative impacts on mental health. In this essay, I will discuss the pros and cons of owning a cell phone from multiple perspectives.From a practical standpoint, owning a cell phone can greatly enhance our lives. It allows us to stay connected with friends and family, access important information, and even work remotely. The ability to make calls, send texts, and access the internet from anywhere provides a level of convenience that was unimaginable just a few decades ago.In emergency situations, having a cell phone can be aliteral lifesaver, allowing us to call for help when needed.On the other hand, the constant connectivity that cell phones provide can also be a double-edged sword. Many people find themselves addicted to their devices, constantly checking for notifications and updates. This can lead to decreased productivity, poor sleep habits, and even strained relationships. The pressure to always be available and responsive can take a toll on our mental and emotional well-being, leading to increased stress and anxiety.Privacy is another major concern when it comes to owning a cell phone. With the rise of social media and data collection, our personal information is more vulnerable than ever. Companies and hackers alike can access our location, browsing history, and even private messages without our knowledge. This lack of privacy can be unsettling and can make us feel like we are constantly being watched and monitored.From a financial perspective, owning a cell phone can also be a significant expense. The cost of the device itself, along with monthly service fees, can add up to asubstantial amount over time. Many people feel pressured to constantly upgrade to the latest model, leading to a cycle of never-ending spending. For those on a tight budget, the cost of owning a cell phone can be a source of stress and financial strain.Despite these drawbacks, there is no denying the impact that cell phones have had on society as a whole. They have revolutionized the way we communicate, conduct business, and access information. In many ways, owning a cell phone has become a necessity for participating in modern life. However, it is important to be mindful of the potential downsides and to use our devices in a balanced and responsible manner.In conclusion, owning a cell phone has its pros and cons. While it provides unparalleled convenience and connectivity, it also comes with potential downsides such as addiction, privacy concerns, and financial strain. It is important for individuals to be aware of these issues and to use their devices in a mindful and responsible manner.Ultimately, the impact of owning a cell phone on our lives will depend on how we choose to use it.。

高考英语一轮阅读理解选练(9)

手惰市安逸阳光实验学校2015高考英语阅读理解选练（9）及答案（一轮）【2014高考英语一模试题】From a small warehouse in North Salt Lake City, Utah, a little-known company called Go Natural CNG is about to release a new home refueling system after more than two years of research.The system, backed by technology giant Parker Hannifin Corp, will fill up quicker than some models—about one gallon an hour—and last up to 20 years, according to Go Natural CNG Chief Executive Lucas Kjar. The unit, expected by the end of the year, will use hydraulic technology to compress (压缩) the gas for vehicle use, he said. He did not say how much the unit would cost.But Go Natural may have a lot of competition. General Electric, Whirlpool and Eaton are all working on home refueling technologies expected to be launched in the next couple of years.General Electric, which received $1.8 million from the government to develop its system, aims to release a unit that will cool natural gas to minus 50 degrees Celsius to extract (提取) water and other contaminates before refueling. GE aims to sell the unit at $500, about a tenth of the cost of current models.General Electric said it was in the development phase and declined to comment on the program’s progress.Honda, which makes the natural gas-fired Honda Civic GX, has contacted GE and Whirlpool to discuss their plans, according to Elmer Hardy, Honda’s senior manager of alternative fuel vehicles.Eaton, which received $3.4 million from the government to develop the technology, is working on a unit at its labs in Southfield, Michigan, that would use liquids to compress the gas instead of the traditional metal pistons(活塞). It aims to make a unit available for $500 by 2015.“We are seeing if we can do it in a way that reduces the price point,”said Clark Fortune, who leads the program at Eaton. “The adoption will improve if the costs come down.”46.

Soon you may be able to throw your wallet away and pay for things with a quick wave of your smart phone over an electronic scanner.In January, Starbucks announced that customers could start using their phones to buy coffee in 6, 800 of its stores. This is the firstpay-by-phone practice in the U. S. , but we’re likely to see more wireless payment alternatives as something called near field communication(NFC) gets into America’s consumer electronics. Last December, some new smart phones which contain an NFC chip were introduced to the public.Already in use in parts of Asia and Europe, NFC allows shoppers to wave their phones a few inches above a payment terminal—a contact-free system built for speed and convenience. But before NFC becomes widely adopted in the U. S. , a few problems need to be worked out, like who will get to collect the profitable transaction (交易) fees. Although some credit card providers have been experimenting with wave-and-pay systems that use NFC-enabled credit cards, cellphone service providers may try to muscle their way into the point-of-sale(POS) market. Three big cellphone service providers have formed a joint venture (合资企业) that will g o into operation over the next 15 months. Its goal is “to lead the U. S. payments industry from cards to mobile phones.”The other big NFC issue, apart from how payments will be processed, is security. For instance, what’s to stop a thief from digitallypi ckpocketing you? “We’re still not at the point where an attacker can just brush against you in a crowd and steal all the money out of your phone,” says Jimmy Shah, a mobile-security researcher. “Users may also be able to set transaction limits, perhaps requiring a password to be entered for larger purchases.”Still uneasy about this digital-wallet business? Keep in mind that ifyou lose your smart phone, it can be located on a map and remotely disabled. Plus, your phone can be password protected. Your walle t isn’t.1. What is predicted to happen in the U. S. ?A. The expansion of cellphone companies.B. The boom of pay-by-phone business.C. The disappearance of credit cards.D. The increase of Starbucks sales.2. The NFC technology can be used to .A. ensure the safety of shoppersB. collect transaction fees easilyC. make purchase faster and simplerD. improve the quality of cellphones3. Three cellphone service providers form a joint venture to .A. strengthen their relationshipB. get a share in the payments industryC. sell more cellphonesD. test the NFC technology4. According to the passage, what can users do if they lose their smart phones?A. Stop the functioning of their phones.B. Set up a password.C. Get all the money out of their phones.D. Cancel large purchases.【参考答案】33.1-4 BCBA【2014高考英语一模试题】CEverybody loves to play board games sometimes, but it is surprising to know how long this pastime has been in existence.

Ma Shwe turned quickly to reach it and pressed the calf with her head and trunk against the rocky bank. Then with a huge effort, she picked it up in her trunk and tried until she was able to place it on a narrow shelf of rock.Just at this moment, she fell back into the river. If she were carried down, it would be certain death. I knew, as well as she did, that there was one spot where she could get up the bank, but it was on the other side from where she had put her calf.While I was wondering what I could do next, I heard the sound of a mother’s love.

Shay asked,“Do you think they’ll let meplay?”Shay’s father knew that most of the boys would not want someone like Shay on their team,but the father also understood that if his son,mentally and physically disabled,were allowed to play,it would give him a much-needed sense of belonging and some confidence.Shay’s father approached one of the boys on the field and asked if Shay could play,not expecting much. The boy looked around and said,“We’re losing by six runs(分)and the game is in the eighth inning(局). I guess he can be on our team and we’ll try to put him in to bat in the final inning. “Shay struggled over to the team’s bench and put on a team shirt with a broad smile and his father had a small tear in his eye and warmth in his heart.

Would they let Shay bat and give away their chance to win the game?Surprisingly,Shay was given the bat. Everyone knew that a hit was almost impossible. The first pitch(投) came and Shay missed.

Instead,the pitcher threw the ball right over the head of the first baseman,beyond the reach of all teammates. The audience and the players from both teams started screaming,“Shay,run to first!“ Never in his life had Shay ever run that far but made it to first base,wide-eyed and shocked.Everyone shouted,“Run to second!“ Catching his breath,Shay awkwardly ran towards second.

In the realm of technological advancement, perhaps nothing has revolutionized communication quite like thecell phone. From its humble beginnings to its omnipresent role in society today, the journey of the cell phone is nothing short of remarkable.To truly appreciate the impact of cell phones, one must first delve into their origins. The concept of mobile telephony dates back to the early 20th century, with pioneers such as Nikola Tesla envisioning a wireless communication system. However, it wasn't until the late20th century that the first practical cell phones emerged.The Motorola DynaTAC 8000X, released in 1983, is widely regarded as the first commercially available cell phone. Weighing nearly two pounds and sporting a hefty price tag, it was a far cry from the sleek, pocket-sized devices weare accustomed to today. Despite its limitations, the DynaTAC marked the dawn of a new era in communication.As technology advanced, so too did the capabilities of cell phones. The 1990s saw the emergence of smaller, more affordable devices, such as the Nokia 5110 and the Motorola StarTAC. These phones boasted features like text messaging and rudimentary games, laying the groundwork for the multimedia powerhouse that the modern cell phone would become.The turn of the millennium brought with it a wave of innovation in the cell phone industry. The introduction of smartphones, led by the likes of BlackBerry and Palm, revolutionized the way we interacted with our devices. Suddenly, phones were no longer just tools for calling and texting; they were pocket-sized computers capable of browsing the internet, sending emails, and running countless applications.However, it was the launch of the iPhone in 2007 that truly changed the game. With its intuitive touchscreeninterface and seamless integration of hardware and software, the iPhone set a new standard for what a smartphone could be. Its App Store, which allowed users to download third-party applications, sparked a thriving ecosystem of developers and entrepreneurs, forever altering the way we access information and entertainment.In the years that followed, smartphones continued to evolve at a breakneck pace. We witnessed the rise of Android, the emergence of social media platforms like Facebook and Twitter, and the advent of features like voice assistants and augmented reality. Today, smartphones are more than just communication devices; they are essential tools for work, entertainment, and staying connected to the world around us.Of course, with great power comes great responsibility. The ubiquity of cell phones has raised concerns about privacy, cybersecurity, and the impact of excessive screen time on our mental and physical health. As we navigate the ever-changing landscape of technology, it is imperativethat we remain vigilant and mindful of the consequences ofour digital dependence.In conclusion, the evolution of cell phones is a testament to the ingenuity and innovation of the human spirit. What began as a clunky, expensive novelty has blossomed into an indispensable tool that shapes every aspect of our lives. As we look to the future, one thing is certain: the story of the cell phone is far from over.。
