21、Sound may offer a creative way to take the ocean's temperature. Climate change is steadily warming the seas, which have absorbed about 90 percent of the excess heat trapped by greenhouse gases. This warming contributes to sea-level rise, endangers species and influences weather patterns.
But tracking the warming is tricky. Ship-based observations capture only snapshots in time over a tiny portion of the water. Satellite observations cannot enter very deep below the surface. The most detailed picture of ocean heat comes from Argo, which can drop down to around 6,500feet. But there are only about 4,000 such floats, and they cannot sample deeper parts of the oceans.
In Science, researchers at the California Institute of Technology and the Chinese Academy of Sciences compared the travel speeds of sounds produced by undersea earthquakes to detect ocean warming over wider areas. Because sound travels faster in warmer water, differences in speed can reveal changing temperatures. "They're opening up a whole new area of study," says Princeton University geophysicist Frederik Simons, who was not involved in the research.
Inspired by those early efforts to measure ocean heat with sound, Caltech researcher Wenbo Wu thought to monitor low-frequency sound waves sent out by earthquakes below the seafloor. “I know these earthquakes are very powerful sources, "Wu says, "So why not try to use the earthquakes?"”
He and his team tested the idea near Indonesia’s island of Nias, where the IndoAustralian Plate is bumping under the Sunda Plate. The researchers gathered sound data from 4,272 earthquakes of magnitude 3 or greater from 2004 to 2016, and they compared sound wave speeds from quakes that originated in the same spot over the years. By modeling the differences, often just fractions of a second, they found that the ocean near Nias was warming by about 0.08 degree Fahrenheit per decade—more than the 0.047 degree F suggested by Argo’s data. Less than one degree F does not sound large, but it takes considerable heat to warm the entire eastern Indian Ocean.
The new method is promising, says University of Hawaii oceanographer Bruce Howe, who was not involved in the work. Meanwhile Simons and his colleagues are exploring an alternative technique, employing dozens of underwater microphones called hydrophones to catch more earthquake sounds. He notes that finding out the floats’ precise locations will be challenging, however. Overcoming such challenges would fill in important gaps, Wu says, “We really need different methods of gathering the data as much as possible.”
【1】What do people do to take ocean’s temperature?
A.Ships sail across all the oceans to take photos.
B.Satellites are used to provide data on ocean heat.
C.Argo enters the deepest seas for detailed pictures.
D.The numbers of floats hit a record high for samples.
【2】Why can sound be a method for detecting ocean warming?

22、If you are sending a text message, watching TV or listening to the radio, you may stop and give this your full attention. Multi-tasking shrinks(使……萎缩) the brain, research suggests.
A study found that men and women who frequently used several types of technology at the same time had less grey matter in a key part of the brain. University of Sussex researchers said, “Using mobile phones, laptops and other media devices simultaneously could be changing the structure of our brains.”
Worryingly, the part of the brain that shrinks is involved in processing emotion. The finding follows research which has linked multi-tasking with a shortened attention span, depression, anxiety and lower grades at school.
The researchers began by asking 75 healthy men and women how often they divided their attention between different types of technology. This could mean sending a text message while listening to music and checking email, or speaking on the phone while watching TV and surfing the internet. The volunteers were then given brain scans which showed they had less grey matter in a region called the anterior cingulated cortex (ACC)(前扣带皮质). Scientists have proved that brain structure can be changed on exposure to fresh environments and experience.
Other studies have shown that training – such as learning to play magic tricks or taxi drivers’ learning the map of London – can increase grey-matter densities(密度) in certain parts.
Experts have also warned of the harmful impact technology can have on our memory and attention span. The University of California team conducted a survey of more than 18,000 people aged between 18 and 99, and found 20% had problems with memory. Researchers were shocked greatly by the 14% of 18 to 39-year-old people who also worried about their memories.
Multi-tasking may shorten attention span, making it harder to focus and form memories, the researchers said, adding that youngsters may be particularly affected by stress.
【1】The underlined word "simultaneously" in Para.2 means _________.
A. on one’s own B. at no time
C. at the same time D. by accident
【2】All of the following are possible effects of multi-tasking except _________.

C. lower grades at school D. depression and anxiety
【3】What can increase grey-matter densities?
A. Sending a text message while listening to music .
B. Students’ doing their homework.
C. Taxi drivers’ learning the map of London.
D. Speaking on the phone while watching TV.
【4】In which section of a newspaper can the passage be found?
A. Entertainment. B. Economy.
C. Tourism. D. Science.
【5】Which of the following can be the best title of this passage?
A. Media multi-tasking is becoming more popular.
B. Multi-tasking shrinks the brain.
C. Multi-tasking may shorten attention span.
D. People are worried about their memories.
23、Professor Heinz Wolff, who has died aged 89, was a bioengineering pioneer. He established the discipline, named it and, in a 60-year career, made significant contributions to medicalresearch.But to the British public, he was best known as the"dotty scientist' who fronted The Great Egg Race, a BBC show in which colour-coded teams were set engineering challenges(the first was to transport an egg in a vehicle powered by rubber bands).With his trademark bow tie, half-moon glasses and Mittel-European accent, he looked really like Professor Branestawn, as described by W. Heath Robinson. Yet while he cheerfully exploited his reputation as a "peculiar egghead'", he was very serious about his work and inspired thousands of young people to consider scientific careers.
Born in Berlin in 1928, Heinz Wolff was the son of Jewish parents.His mother died in 1938, and the next year the family fled.They arrived in Britain on the day war was declared."We really cut it rather fine," he said on Desert Island Discs in 1998.After leaving school, he worked as a technician at the Radcliffe Infirmary in Oxford.where he invented a machine to count red blood cells, and then at the National Institute for Medical Research's pneumoconiosis research unit in Cardiff, where he designed a means of measuring dust levels in coal miners.He went on to study at University College London and graduated with a first in physics and physiology. Then, in 1983, he founded the Institute for Bioengineering at Brunel University.His particular interest was in technologies to improve the lives of older people, but he was also heavily involved in space research and worked as an adviser to the European Space Agency.
Wolff had made his first appearance on TV on Panorama in 1966,encouraging Richard Dimbleby to swallow a“radio pill'".On The Great Egg Race, which ran from 1979,his task was to get opponent teams representing organizations such as the chemical company ICI. Challenges included building a hovercraft from a lawnmower, and inventing a bicycle that could ride on water.Marks were awarded for entertainment value and technical accomplishment.The show ended in the mid-l980s,but Wolff continued to judge scientific competitions, on TV and elsewhere. A natural entertainer with an inexhaustible curiosity about the world, he said he'd be happy to dress up as a clown if it got children interested in science.
【1】The word “dotty” (paragraph1) is closest in meaning to ________ .
A.peculiar
B.serious
C.famous
D.genius
【2】Which of the following statements is TRUE of Heinz Wolff according to the passage?
A.His family left Berlin after World War II began.
B.He used to major in physics and physiology.
C.He invented a machine while in University College London.
D.His interest lay in helping those living in war-stricken areas.
【3】Heinz Wolff didn't mind looking ridiculous as long as _________ .
A.he could keep being curious about the world
B.he could combine entertainment and technology
C.he could help arouse children's interest in science
D.he could appear on TV to judge scientific competitions
【4】Which of the following is an achievement made by Heinz Wolff?
A.Representing a chemical company.

C.Being the first scientist to front TV shows.
D.Setting up the subject of bioengineering.
24、Mr William Shakespeare and the Internet
Explanation of Contents
This is the fourth edition of these pages. It is hard to believe, but once again they are new and improved. My motive in publishing these pages remains to help and stimulate others in Shakespeare studies, and especially those who might contribute their work to the Internet. The spirit of altruism (利他主义) that originally built the Internet is not quite gone, though, sadly, through the pressure of time and profit has lessened.
A major new addition to the pages is a Shakespeare Timeline, which is an online biography mounted at this site. The problems with searching for Shakespeare resources using the available Search Engines are:
---- It is difficult to focus most searches so that you get a manageable number of relevant hits;
---- It is impossible by simply reading an abstract(摘要) to make any distinction between the output of a Junior High School student and that of a professional researcher.
Another change in these pages over previous editions is the “What’s News” page. If you come away from these pages with the feeling that they are very useful but slightly pedantic (学究的), I will have realized my goal.
An Apology
I am continually apologizing to the many who have written me requesting revisions of the pages. We are all too busy. I simply have not had the time to dedicate to these pages that I wish. But I love the material and so have, at long last, made some time to update them.
A Reminder to Young Students
These pages contain the best links I can find to Shakespeare on the Internet. As a reminder, I would say I very much enjoy hearing from people who view and use these pages. If you want to do Shakespeare research using the web, this page is a great starting point, and I keep it as current as I can. The web is in its infancy(初期in bringing good, scholarly content to students. Don’t forget the best, if not quickest, resources are still in your library.
【1】The passage is written to ________.
A. introduce the fourth edition of these pages
B. make an apology to readers
C. show off these pages to readers
D. let Shakespeare researchers buy these pages
【2】When searching for Shakespeare resources using Search Engines, you ________.
A. can easily recognize what the abstract means
B. will waste some time in finding what you want
C. will often come into the “What’s News” pages
D. will find something special on your computers
【3】Which of the following can best conclude the last paragraph?
A. The writer will often read letters from those who use these pages.
B. The writer of the passage is very selfish.
C. The web was just created four years ago.
D. Shakespeare researchers should first of all refer to these pages.
25、 President Obama’s second Inaugural Address used soaring language to stress America’s commitment to the dream of equality of opportunity: ‘We are true to our belief that a little girl born into _______ knows that she has the same chance to succeed as anybody else, because she is an American’.
The gap between ideal and reality could hardly be _______ . Today, the United States has less equality of opportunity than almost any other advanced industrial country. Study after study has _______ the myth that America is a land of opportunity. A way of looking at equality of opportunity is to as to what extent the life chances of a child are _______ the education and income of his parents. Is it just as likely that a child of poor or poorly educated parents gets a good education and rises to the middle class as someone born to middle-class parents with college degrees? Even in a more democratic society. the answer would be no.
How do we explain this? Some of it has to do with discrimination (歧视). Latinos and African-Americans still get paid less than whites, and women still get paid less than men, _______ they recently surpassed (超越)men in the number of advanced degrees they obtain. Discrimination, however, is only a small part of the _______. Probably the most important reason for _______ of equality of opportunity is education. After World WarⅡ, we made a major effort to _______ higher education to Americans across the country. But then we changed, in several ways. While racial segregation(种族隔离)decreased, economic segregation increased. After 1980, the poor grew poorer, the middle stagnated(停滞不前), and the top did better and better. A result was a widening gap in educational performance – the _______ gap between rich and poor kids born in 2001 was 30 to 40 percent larger than it was for those born 25 years earlier, a Stanford sociologist found. Of course, there are other forces ______ . Children in rich families get more exposure to reading. Their families can afford enriching experiences like music lessons and summer camp. They get better nutrition and health care, which enhance their learning, directly and indirectly.
Now Americans are coming to realize that without extensive policy changes, their long cherished belief is only a myth. It is unreasonable that a rich country like the United States has made _______ to higher education so difficult for those at the bottom and middle. There are many _______ ways of providing chances for more to receive higher education, from Australia’s income-contingent loan program to the near-free system of universities in Europe. A more educated population produces greater innovation, and a booming economy. Those benefits are why we’ve long been ______ to free public education through 12th grade. But while a 12th-grade education might have been enough a century ago, it isn’t today. Yet we haven’t _______ our system to contemporary realities.
The steps I’ve outlined are not just affordable but necessary. Even more important, though, is that we cannot afford to let our country drift farther from _______ that the vast majority of Americans share. We will never fully succeed in achieving Mr. Obama’s vision of a poor girl’s having exactly the same opportunities as a wealthy girl. But we could do much, much better, and must not rest until we do.
