1、2022年职称英语-理工-B类每日一练06-03-职称英语-理工-B类Bill Gates: Unleashing Your CreativityIve always been an optimist and I suppose it is rooted in1 my belief that the power of creativity and intelligence can make the world a better place.For as long as I can remember, Ive loved learning new things and solving probl
2、ems. So when I sat down at a computer for the first time in seventh grade, I was hooked. It was a clunky old teletype machine and it could barely do anything compared to the computers we have today.2But it changed my life.When my friend Paul Allen and I started Microsoft30 years ago，we had a vision
3、of “a computer on every desk and in every home”, which probably sounded a little too optimistic at a time when most computers were the size of refrigerators. But we believed that personal computers would change the world .And they have.And after 30 years, Im still as inspired by computers as I was b
4、ack in seventh grade.I believe that computers are the most incredible tool we can use to feed our curiosity and inventiveness to help us solve problems that even the smartest people couldnt solve on their own.Computers have transformed how we learn，giving kids everywhere a window into all of the wor
5、lds knowledge. Theyre helping us build communities around the things we care about and to stay close to the people who are important to us, no matter where they are.3Like my friend Warren Buffett, I feel particularly lucky to do something every day that I love to do. He calls it “tap-dancing towork”
6、4. My job at Microsoft is as challenging as ever, but what makes me “tap-dancing to work” is when we show people something new, like a computer that can recognize your handwriting or your speech, or one that can store a lifetimes worth of photos, and they say, “I didnt know you could do that with a
7、PC5! ”But for all the cool things that a person can do with a PC，there are lots of other ways we can put our creativity and intelligence to work to improve our world6. There are still far too many people in the world whose most basic needs go unmet7. Every year, for example, millions of people die f
8、rom diseases that are easy to prevent or treat in the developed world.I believe that my own good fortune brings with it a responsibility to give back to the world. My wife, Melinda, and I have committed to8 improving health and education in a way that can help as many people as possible.As a father,
9、 I believe that the death of a child in Africa is no less poignant or tragic than9 the death of a child anywhere else, and that it doesnt take much to make an immense difference in these childrens lives10.Im still very much an optimist, and I believe that progress on even the worlds toughest problem
10、s is possible and its happening every day. Were seeing new drugs for deadly diseases, new diagnostic tools，and new attention paid to the health problems in the developing world.Im excited by the possibilities I see for medicine, for education and, of course, for technology. And I believe that throug

17、he road in more ways than one. Two new studies show that talking on the phone while traveling, whether youre driving or on foot, is increasing both pedestrian deaths and those of drivers and passengers, and recommend crackdowns on cell1use by both pedestrians and drivers.The new studies, lead-author
18、ed by Rutgers University, Newark, Economics Professor Peter D. Loeb2, relate the impact of cell phones on accident fatalities to the number of cell phones in use, showing that the current increase in deaths resulting from cell phone use follows a period when cell phones actually helped to reduce ped
19、estrian and traffic fatalities. However, this reduction in fatalities disappeared once the numbers of phones in use reached a “critical mass”3 of 100 million, the study found.These studies looked at cell phone use and motor vehicle accidents from 1975 through 2002, and factored in4a number of variab
20、les, including vehicle speed, alcohol consumption, seat belt use, and miles driven. The studies found the cell phone-fatality correlation to be true even when including factors such as speed, alcohol consumption, and seat belt use.Loeb and his co-author determined that, at the current time, cell pho
21、ne use has a “significant adverse effect on pedestrian safety” and that “cell phones and their usage above a critical threshold5adds to motor vehicle fatalities.” In the late 1980s and part of the 1990s, before the numbers of phones exploded, cell phone use actually had a “life-saving effect” in ped
22、estrian and traffic accidents, Loeb notes. “Cell-phone users were able to quickly call for medical assistance when involved in an accident. This quick medical response actually reduced the number of traffic deaths for a time,” Loeb hypothesizes.However, this was not the case when cells were first us
23、ed in the mid-1980s, when they caused a “life-taking effect” among pedestrians, drivers and passengers in vehicles. In those early days, when there were fewer than a million phones, fatalities increased, says Loeb, because drivers and pedestrians probably were still adjusting to the novelty of using
24、 them, and there werent enough cell phones in use to make a difference in summoning help following an accident, he explains.The “life-saving effect” occurred as the volume of phones grew into the early 1990s, and increasing numbers of cells were used to call 911 following accidents, leading to a dro
25、p in fatalities, explains Loeb. But this life-saving effect was canceled out6once the numbers of phones reached a “critical mass” of about 100 million and the “life-taking effect” - increased accidents and fatalities outweighed the benefits of quick access to 911 services, according to Loeb.Loeb and
26、 his co-authors used econometric models to analyze data from a number of government and private studies. He and his co-authors recommend that governments consider more aggressive policies to reduce cell phone use by both drivers and pedestrians, to reduce the number of fatalities.词汇：crackdown n.制裁，严

30、xpressions ever invented. In movies and plays, music has an added function1: it not only moves people but also can shock people. Is it true that an ordinary musical instrument can be so powerful?Our eardrums can withstand sound within 20 to 80 decibels. Once sound exceeds this limit2, even beautiful
31、 music will become car-splitting noise3and harm health. A strong blast of high sound can twist and break a solid iron sheet. 1 The noise from a planes engine is over 140 decibels. However, the sound of a flute is at most a few decibels. 2 It has been proven that people who have worked in an environm
32、ent with a high sound intensity for a long time suffer varying degrees of heart disease or altered brain waves.In movies, sometimes the hero can produce a sound that ordinary people cant hear and only those who have the same ability can feel. In nature, there is actually sound that is beyond our hea
33、ring. In physics, the sound that exceeds 20,000 Hz is called ultrasonic. 3 It does no harm to health.Sound less than 20 Hz is called infrasonic waves. When we move, the air will vibrate. 4 As the frequency of infrasonic waves is close to that of peoples internal organs4, infrasonic wave may cause re
34、sonance in human bodies. As a result, peoples vision may weaken and internal organs may rupture. However, whether an infrasonic wave can be used as a weapon depends on its intensity5. If its intensity is very low, it wont damage internal organs or a persons health. 5 When wind blows at a force of 3
35、or 4 over the sea6, it will produce infrasonic waves of several decibels. Only typhoons can produce infrasonic waves of over 100 decibels. At present, scientists can only produce infrasonic weapons in the lab with the help of advanced scientific tools and powerful electric power.词汇：Immigrant / mgrnt

The technique cannot yet pick up electrical activity in the human brain because the current there is too small, but Xiao doesnt rule it out4 in the future. “I can never say never,” he says.Although the rese
