AC/DC have postponed their US tour after singer Brian Johnson was warned by doctors that he was at risk of “total hearing loss”. This is unsurprising, given the decades that the Australian band has been pumping out the hard rock decibels(分贝). But deafness isn’t only a concern for rock musicians. In recent years it has become clear that anyone around music a lot has reason to be equally worried.
When exposed to music, risk to hearing arises from a combination of how loud the sound is and how long you’re exposed to it. If you visit a nightclub that is thumping out (响亮地奏出) music on the dance floor at 100 dB, then after only 10-15 minutes the exposure is potentially damaging. In a quieter part of the club, but where the music is still loud enough that you have to shout at your friends, then you could be there for a couple of hours before having to worry about your hearing. Of course music frequently exceeds(超过) 80-85 dB, but what counts most in assessing the risk to hearing is the average exposure.
Exposure to high noise levels often causes temporary deafness — something many people have experienced after going to a nightclub. While hearing usually recovers after a few hours or days, repeated loud exposure leads to permanent hearing damage. Initially, this damage is subtle and unlikely to be noticed by the listener. Problems only becomes significant in middle age when the noise-induced hearing loss combines with the natural loss of hearing due to ageing.
Improved technology means that the number of musicians having to give up performing could decrease, but student musicians need to be educated about the dangers of noise-caused hearing loss. The increasing use of headphones will also work against this — for musicians and everyone else. Unless people are careful with the volume(音量) level on their portable music players, hearing loss caused by music will increase.

AC/DC have postponed their US, tour after singer Brian Johnson was warned by doctors that he was at risk of“ total hearing loss". This is unsurprising that the Australian band has been pumping out the hard rock decibel(分贝). But deafness isn't only a concern for rock musicians. Anyone around music a lot has reason to be equally worried.
When you are exposed to music, risk to hearing arises from a combination of how loud the sound is and how long you' re exposed to it for. If you visit a nightclub with music at 100 dB, then after only 10~15 minutes the exposure is potentially damaging. In a quieter part of the club, but where the music is still loud enough that you have to shout at your friends, them you could be there for a couple of hours before having to worry about your hearing. Of course music frequently exceeds (超过) 80~85 dB, but what counts most in assessing the risk to hearing is the average exposure.
Exposure to high noise levels often causes temporary deafness-something many people have experienced after going to a nightclub. While hearing usually recovers , repeated loud exposure leads to permanent hearing damage. Initially, this damage is unlikely to be noticed by the listener. Problems only become significant in middle age when the noise-caused hearing loss combines with the natural loss of hearing due to ageing.
Often orchestras employ screens or “musicians ear plugs” to block sound from the loudest instruments. These decrease sound without completely blocking everything out and are very useful in rehearsal(训练),but get in the way of balancing the sound in a concert. Professional orchestras also look at how they schedule music to ensure that musicians are exposed to a mixture of quiet and loud pieces. Given how loud their instruments are, drummers are particularly at risk, but using era plugs can go some way to reducing potential hearing loss. For rock and pop musicians, using in-ear monitors has the potential to reduce noise exposure.
Improved technology means the number of musicians having to give up performing could decrease, But student musicians need to be educated about the dangers of noise-caused hearing loss. The increasing use of headphones will also work against this. Unless people are careful with the volume level on their portable music players, hearing loss caused by music will increase.
1.What does the author mainly want to show by mentioning Brian Johnson?
A. Hearing loss are very common nowadays.
B. Music and hearing loss are closely related.
C. Being with music isn't always beneficial.
D. Deafness has become musicians' major concern.
2.What matters most in evaluating the risk of hearing loss according to the text ?
A. The rhythm of music.
B. The average exposure of time.
C. The playing environment of music.
D. The listener's sensitivity to sound.
3.What dose Paragraph 4 mainly talk about ? .
A. How the sound in a concert is balanced.
B. How professional orchestras schedule music .
C. How musicians can decrease their risk of hearing loss.
D. How different musicians work together in an orchestra.
4.Which of the following best reflects the author's opinion?
A. Improved technology can prevent hearing damage.
B. Student musicians are main sufferers of hearing loss.
C. Using headphones helps reduce hearing loss to a degree.

高三英语单项填空简单题查看答案及解析
Malia Obama, the elder daughter of former US President Barack Obama, would postpone enrolling in Harvard. She would take a gap year.
Gap years are so popular in Britain that more than 200,000 students take them every year. However, they are virtually unknown to many students in the US. Only about 1 percent of graduating seniors, or about 30,000 Americans students, decide to take a year off between high school and college.
Gap years, as defined by most US colleges, are structured educational periods of travel, volunteering or other kinds of learning through experiences. They usually have to be approved by the colleges which students plan to attend, and more American students, like Malia Obama, have started to take gap years.
According to American Gap Association(AGA)surveys, there was a 22 percent increase in students taking gap years in 2015 over the previous year.
While many colleges and particularly public universities don’t allow students to postpone enrollment, Florida State Universality has begun encouraging its freshmen to take a year off from their studies in order to get some extra maturity and new experience.
“We know very clearly now that gap years can be an educational experience that changes you completely,” said Joe O’shea, the president of(AGA),“Gap years help increase students’ focus while their identities and future plans take shape.”
She believes gap years are good ways for young people to get away from their comfortable lives or pressures from society, and to see their lives from a new angle. “It helps you choose your path, instead of letting it choose you.
Karis Engle spent a year with a charitable organization in Haiti at age 18. The experience has made her realize that she wants to help others. Now Engle has become the president of the Glades Initiative, a non-profit organization that helps with food security in communities in southern Florida. She said the immersion in a very different culture completely changed her worldview. By the time she entered Bethel College in Kansas a year later, her life had changed. “I felt like I was different from most people there. I knew clearly what I wanted to study, which was international development with an emphasis on social work.”

3.Karis Engle thinks ________.
A. taking gap years has influenced her cultural choices
B. taking gap years seldom affects participants’ worldview
C. taking gap years is very valuable for her to choose her career
D. taking gap years is helpful for her entry into college

One after another, telecommunications giants (通信巨头) have announced their latest fifth generation (5G) products. They have also claimed that 5G technology would be used on a massive scale by 2020. Yet, when reporting about 5G, many domestic media outlets have described it as a “much faster” technology than 4G without mentioning any of its other advantages. As a result, the common public view about 5G is that they could “download a high-density movie within one second”. Beyond that, most people know nothing about 5G.
Actually, 5G technology has many more advantages than 4G apart from speed. According to the criteria of 3GPP, an international standardization organization, 5G technology can be used for at least three purposes—for connecting everything, reliability of connections, and eliminating delays.
“Connecting everything” is an appropriate slogan for 5G technology, without which the Internet of things would be impossible. 5G would enable one server to connect to multiple terminals (终端) and thus establish high-speed coordination among them, and help the chips inside the terminals to timely react to meet people’s needs. Take for example, autonomous vehicles, which are mature technology products. Self-driving cars combine a variety of sensors, such as radar, computer vision, and GPS to identify navigation paths and obstacles. 5G technology will link all the elements of a transportation system, such as traffic lights, cameras and, of course, cars to establish perfect coordination so they can avoid obstacles and move on navigation paths, which will help strengthen self-driving technology.
Reliability of connections is another essential characteristic of 5G technology, whose use can be extended to other fields where high safety standards are required. For instance, in certain surgeries, surgeons insert nano-robots inside a patient’s body and have to maintain constant control over the robots to ensure they perform their functions and do not cause any harm to the patient. This is an technology can be of great help, as it can establish reliable and continuous connections between the monitor and the nano-robots.
1.What will the author most probably discuss in the paragraph that follow?
A.Eliminating delays. B.5G network capacity.
C.Disadvantages of 5G. D.Building 5G base stations.
2.Which can also serve as an example of “connecting everything”?
A.Improvement of smart phone signals.
B.Decrease in telecommunication cost.
C.High speed in-playing computer games.
D.Online tests for all members at the same time.
3.Why can 5G be used in fields with high safety standards?
A.It can attract most eyeball on a massive scale.
B.It can provide dependable and constant service.
C.It offers massive machine type of communication.
D.It employs 4G base stations and occupy less space.
4.What would be the best title for the passage?
A.5G Technology: More Than about High Speed
B.5G Technology Will Shape the Future of Connectivity
C.Telecom Giants Work Together to Better 5G Technology
D.Advantages and Disadvantages of 5G Technology and Products

In only two decades Asian Americans have become the fastest-growing US minority. As their children began moving up through the nation’s schools, it became clear that a new class of academic achievers was forming. Their achievements are reflected in the nation’s best universities, where mathematics, science and engineering departments have taken on a decidedly Asian character. This special liking for mathematics and science is partly explained by the fact that Asian-American students who began their educations abroad arrived in the US with a solid grounding in mathematics but little or no knowledge of English.They are also influenced by the promises of a good job after college. Asians feel there will be less unfair treatment in areas like mathematics and science because they will be judged more objectively. And the return on the investment in education is more immediate in something like engineering than with an arts degree.
Most Asian-American students owe their success to the influence of parents who are determined that their children take full advantage of what the American educational system has to offer. An effective measure of parental attention is homework. Asian parents spend more time with their children than American parents do, and it helps. Many researchers also believe there is something in Asian culture that causes success, such as ideals that stress family values and emphasize education.
Both explanations for academic success worry Asian Americans because of fears that they feed a typical racial image. Many can remember when Chinese, Japanese and Filipino immigrants were the victims of social separation. Indeed, it was not until 1952 that laws were laid down giving all Asian immigrants the right to citizenship.
1.. While making great achievements at college, Asian-American students ________.
A.feel they are mistreated because of limited knowledge of English |
B.are afraid that their academic successes bear a strong Asian character |
C.still worry about unfair treatment in academic areas |
D.generally feel it a shame to have to depend on their parents |
2.. What are the major factors that determine the success of Asian Americans?
A.Solid foundation in basic mathematics and Asian culture. |
B.Hard work and intelligence. |
C.Hard work and a limited knowledge of English. |
D.Asian culture and the American educational system. |
3..Few Asian-American students major in human sciences mainly because_________.
A.their English is not good enough |
B.they are afraid they might meet with unfair judgment in these areas |
C.there is a wide difference between Asian and Western cultures |
D.they know little about American culture and society |
4.. The author’s tone in this passage is __________.
A.sympathetic | B.doubtful | C.critical | D.objective |
