One area where this is particularly evident is education. Traditional classroom learning is being complemented by digital tools that allow for personalized learning experiences. Online courses, educational software, and mobile applications are changing the way students learn and teachers teach.Technology has made it possible for students to access educational resources from anywhere at any time, provided they have an internet connection. This flexibility has opened up opportunities for those who might not otherwise be able to attend traditional schools due to geographic or financial constraints. However, while technology offers many benefits, it also poses challenges. Not all students have equal access to these technological resources, which can lead to disparities in educational outcomes. Furthermore, the reliance on technology raises questions about the skills that students will need in the future, as well as the roles of educators in guiding them.Despite these challenges, the integration of technology into education continues to grow. As we move forward, it will be essential to ensure equitable access to technology and to prepare students for a future where digital literacy is as crucial as traditional academic skills.Questions:1、The passage states that technology plays a minor role in education.Answer: False2、According to the text, online courses are one example of how technology complements traditional learning.Answer: True3、Technology has made education less accessible to people with financial limitations.Answer: False4、The passage suggests that the use of technology in education does not create any disparities.Answer: False5、Educators will need to adapt their roles to include guiding students in developing digital literacy.Answer: True第二题Read the following passage and then answer the questions below it.The internet has revolutionized the way we communicate and accessinformation.

It is a means of acquiring knowledge, understanding different perspectives, and expanding our horizons. In today’s fas t-paced world, where information is readily available at our fingertips, the significance of reading as a habit cannot be overstated.Books have the power to transport us to faraway lands, introduce us to fascinating characters, and spark imaginations.

Moreover, reading regularly can improve cognitive abilities, enhance vocabulary, and foster empathy.In an era where technology dominates our lives, it is easy to overlook the benefits of traditional reading. However, research has shown that digital distractions can hinder deep thinking and concentration. On the contrary, reading physical books or even e-books without distractions can significantly improve focus and comprehension.Beyond personal growth, reading is also a crucial skill for academic and professional success. It is a fundamental requirement for many educationalprograms and job positions. Students who read regularly perform better academically and develop critical thinking skills that are highly valued in today’s workforce.Furthermore, reading promotes lifelong learning.

All of this will be in the future of sport. The spectator (the television audience) will be the priority and professional clubs will have to readjust their structures to adapt to the new reality: sport as a business.The new technologies will mean that spectators will no longer have to wait for broadcasts by the conventional channels. They will be the ones who decide what to see. And they will have to pay for it. In the United States the system of the future has already started: pay-as-you-view. Everything will be offered by television and the spectator will only have to choose. The review Sports Illustrated recently published a full profile of the life of the supporter at home in the middle of the next century. It explained that the consumers would be able to select their view of the match on a gigantic, flat screen occupying the whole of one wall, with images of a clarity which cannot be foreseen at present; they could watch from the trainer’s stands just behind the batter in a game of baseball or from the helmet of the star player in an American football game. And at their disposal will be the sane option s the producer of the recorded programmer has to select replays, to choose which camera to me and to decide on the sound whether to hear the public, the players, the trainer and so on.Many sports executives, largely too old and too conservative to feel at home with the new technologies will believe that sport must control the expansion of television coverage in order to survive and ensure that spectators attend matches. They do not even accept the evidence which contradicts their view while there is more basketball than ever on television, for example, it is also certain that basketball is more popular than ever.It is also the argument of these sports executives that television harming the modest team. This is true, but the future of those teams is also modest. They have reached their ceiling . It is the law of the market. The great events continually attract larger audience.The world I being constructed on new technologies so that people can make the utmost use of their time and , in their home have access to the greatest possible range of recreational activities. Sport will have to adapt itself to the new world.The most visionary executives go further. That philosophy is: rather than see television take over sport why not have sports taken over television?1．What does the writer mean by use of the phrase “an indissoluble marriage” in the first paragraph?A．sport is combined with television. B．sport controls television. C．Television dictates sports.D．Sport and television will go their own ways2．What does “they” in line 2 paragraph 2 stand for?A．Broadcasts. B．Channels. C．Spectators. D．Technologies. 3．How do many sports executives feel with the new technologies?A．they are too old to do anything. B．They feel ill at ease. C．They feel completely at home.

C．Television coverage expansion.D．An example to show how sport has taken over television.5．What might be the appropriate title of this passage?A．The arguments of sports executives B．The philosophy of visionary executives C．Sports and television in the 21st century D．Sports: a businessPassage 2Don't have time to read anymore? Now you can get free, quick literature via email. More than 100,000 people open their email each day to read a chapter of a book, through Chapter-A-Day, an online book club created two years ago. It's a free email service that provides a short daily reading for busy people, exposing them to literature they may not find on their own, inspiring some to recommit to the reading habit. About 550 public library systems representing over 3,000 branch libraries already have signed up to offer Chapter-A-Day. Via email, participants get about five minutes' worth of reading every day. After three chapters are emailed, the installments stop, and those who want to keep reading can borrow the book at their public library or purchase it online. Chapter-A-Day has eight free book clubs, and sells thousands of books each month.Chapter-A-Day started in 1999 when Suzanne Beecher, a lifelong book lover, realized how many of the women who worked part-time for her software development company didn't have time in their busy lives to read. She decided to type part of a chapter of a book, and send it to her employees through email. The next day she typed a little more, and continued to send literary installments each day. She says she started getting feedback from the staff about how reading made them feel. "They were interested, and realized that, though they didn't have time in their busy lives for reading, just reading that little bit each day got them back in the habit". Realizing that many other people could benefit, she decided to take the idea even further and start an email "chapter-a-day" book club to help others ease their way back into daily reading. "Reading makes changes in people's lives." Beecher says.Pat Dempsey, a librarian at a public library in Ohio, has found Chapter-A-Day helps her library clients get back in the habit of reading. "It's a different way to get people hooked on books," she says.6. Chapter-A-Day is intended to help people _.A. get back into the habit of readingB. relieve stress from office workC. find interesting books onlineD. buy books more conveniently7. The passage was written in _.A. 1999B. 2000C. 2001D. 20028. It can be inferred that through Chapter-A-Day _ _.A. public libraries have become crowded with readersB. MS Beecher made much money for her software companyC. people begin to read very slowly and patientlyD. people cannot finish reading any book online9. The word "installment" in t he passage probably means “”.A. a library emailB. a rare piece of literatureC. a free novelD. a part of a book10. Ms Beecher decided to expand her Chapter-A-Day service because .A. over 3,000 libraries had joinedB. many other people could benefitC. eight book clubs supported herD. free email service was availablePassage 3According to the United States government, people are classified as homeless if they have no place to stay and no expectation of finding a place for the next thirty days. Although technically accurate, that is an impersonal assessment of an enormous and very human problem.The homeless population represents all of us Americans. It includes men and women, the elderly, children, andinfants. Its members are from all ethnic (种族的) groups. What they have in common is poverty.Currently in the U.S., thirty-nine million people live in poverty. When money is really tight, paying the rent or buying food often becomes a choice. Government assistance in the form of food stamps does help but, as one homeless man explains, you can’t pay the rent with food stamps.With no money for rent, the streets and homeless shelters become the alternative.Although men constitute the largest group within the homeless population, homeless women with children are rapidly joining them. In fact, one quarter of the homeless people in the U.S. are teenagers and young children.People may become homeless for numerous reasons. However, there are certain factors that many of these individuals have in common. They include a lack of adequate education and job skills. A majority of the teenagers and adults have not completed high school.The abuse of alcohol and drugs is also a common factor. One third of the adult homeless population abuses alcohol, while one quarter of the same group uses drugs.Some members of this population suffer mental health problems. Within the past several years many institutions for the mentally ill have been closed and their patients sent “home”. Unfortunately, a number of those people have no home to go to and they are unable to adequately look after themselves.Job loss in today’s economy has also become a real factor in the loss of people’s ho mes. The breakup of families through abandonment and divorce are also contributing factors, particularly when there are children involved. The parent who is left to care for the kids with inadequate income may be forced to depend on the homeless shelters to put a roof over their heads.11. The writer thinks that the U.S. government’s definition of the homeless reveals ______.A. an insincere attitude toward the homelessB. an unbearable attitude toward the homelessC. an uncivilized attitude toward the homelessD. an unsympathetic attitude toward the homeless12. The U.S. government helps the homeless by ______.A. giving them homeless allowancesB. giving them food stampsC. finding jobs for themD. finding residences for them13. Most of the homeless in the U.S. are ______.A. male adultsB. female adultsC. the elderlyD. children14. People become homeless for all the following reasons EXCEPT ______.A. the lack of adequate educationB. the abuse of alcohol and drugsC. the closure of institutions for the mentally illD. the poor performance of economy15. The breakup of families is likely to lead to homelessness because a parent with kids may ______.A. lose his or her job in today’s economyB. be unable to look after the kidsC. not have enough incomeD. find residence at a homeless shelterPassage 4In early 2004 eight tiny sensors were dropped from a plane near a military base in California. After hitting the ground, the sensors—also known as smart dust sensors—organized themselves into a network and quickly detected a fleet of military vehicles on the ground. The determined the direction, speed and size of a series of military vehicles traveling along the road and later transmitted the data to a computer at a nearby base camp.Smart dust sensors are minicomputers—as small as a grain of rice in some cases—that can monitor and evaluate their physical environment and can relay the information via wireless communication. They can monitor elements such as temperature, moisture, humidity, pressure, energy use, vibration, light, motion, radiation, gas, and chemicals. These devices will soon have many applications, such as use in emergency rescue.Software has been developed to run these minicomputers. A key feature of the software is the ability of the sensors to automatically organize themselves into a communications network and talk to each other via wireless radio signals. If any one connection is interrupted, the sensors will self-correct and pass the information on to the next available sensor.Each sensor has a chip that does the computing work—recording things like temperature and motion at its location. Each sensor also has a tiny radio transmitter that allows it to talk to other sensors within 100 feet or so. With a single network of 10,000 sensors—thought to be the biggest array (阵列) of sensors currently possible—you could cover 9 square miles and get information about each point along the way. The data finally works its way to a base station that can send the information to a computer or to a wireless network.The scientists who are working with this technology say smart dust sensors can be used to detect the location or movement of enemy troops in areas too dangerous or remote for soldiers to operate. Scattering hundreds of self-networking sensors from a manned or unmanned plane onto the battlefield, in theory, could produce critical information and lead to strategic advantage. Sensors could also be used to detect the presence of chemical weapons and could give troops the time needed to put on protective gear.16. Smart dust sensors can do all the following EXCEPT ______.A. giving troops their protective gearB. organizing themselves into a computer networkC. detecting the movement of military vehicles nearbyD. operating in remote and dangerous war zones17. By “physical environment” (Paragraph 2), the writer means such elements as ______.A. the position of military troopsB. the presence of minicomputersC. the strength of radio signalsD. the amount of water vapor in the air18. If connection between two sensors is blocked, the network will automatically ______.A. replace the sensor involvedB. repair the sensor involvedC. ignore the sensor involvedD. destroy the sensor involved19. To cover an area of 3 square miles and get information about each point along the way, how many smart dust sensors are needed?A. About 3,000 sensors.B. About 3,300 sensors.C. About 5,000 sensors.D. About 6,600 sensors.20. The passage implies that the smart dust sensors are most likely to be used in ______.A. emergency rescueB. monitoring pollutionC. military operationsD. evaluating the environmentPassage 5The differences in living standards around the world are vast．In 1993，the average American had an income of about$25，000.In the same year，the average Mexican earned$7，000，and the average Nigerian camed$1，500,Not surprisingly，this large variation in average income is reflected in various measures of the quality of life．Changes in living standards over time are also 1arge．In the United States，incomes have historically grown about 2 percent per year(after adjusting for changes in the cost of living)．At this rate，average income doubles every 35years．In some countries，economic growth has been even more rapid．In Japan，for instance，average income has doubled in the past 20 years，and in South Korea it has doubled in the past 10years．What explains these 1arge differences in 1iving standards among countries and over time? The answer is surprisingly Simple．A1most a11 variation in 1iving standards is attributable to differences in countries’ productivity-----that is，the amount of goods and services produced from each hour of a worker's time．In nations where workers can produce a large quantity of goods and services per unit of time，most people enjoy a high standard of living；in nations where workers are less productive，most people must endure a more meager existence．Similarly，the growth rate of a nation's productivity determines the growth rate of its average income．The fundamental relationship between productivity and living standards is simple，but its implications are far-reaching．If productivity is the primary determinant of livings standards，other explanations must be of secondary importance．For example，people might think that labor unions or minimum-wage 1aws contributed to the rise in 1iving standards of American workers over the past century. Yet the real hero of American workers is their rising productivity．The relationship between productivity and living standards also has great implications for public po1icy．When thinking about how any policy will affect living standards，the key question is how it will affect our ability to produce。
