文章摘要:2017年四川中级职称英语备考阅读理解每日一练,大小罗卡卡都是在20岁就进入巅峰,在萨拉赫这个年纪开始走下坡路的作为前锋,这有点大器晚成的意思,状态能保持三年就不错了。是啊。那球就是和后卫1对1,至少能拉开机会射门吧!还是太年轻,虽然身价不低,当球星还是要成长啊。书包努力给库里做球,几次投篮无果,书包眼看不行,自己简单中投俩,稳住了又给库里做球,终于迎来了库里发挥。感觉这样的书包很可怕啊。,如果我是巴萨的教练,昨晚淘汰的就是罗马,一句话:上一场我们1比4输了,这一场我们必须翻盘。浓眉也许还行,算是卡佩拉的全方位终极强化版。考辛斯和阿德拉开空间的作用也有,但是总体防守和护框能力差了。正好大陆没有一个合适的时机派战机穿岛巡航,若美航母穿越台湾海峡,正好提供了这样一个好机会。届时,大陆要做好万全准备,若台独武力攻击,则立即发动收台战争。至于届时的美航母,必须立即滚蛋,否则一并收拾之。若台及美面对我穿岛巡航无计可施,则此后穿岛巡航常态化,直至台湾回归之后。。

  The Magic of Sound

  Music is one of the most beautiful forms of artistic expressions ever invented. In movies and plays, music has an added function: 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 limit, even beautiful music will become ear-splitting noise and harm health. A strong blast of high sound can twist and break a solid iron sheet. High sound of 150 decibels can kill a healthy rat.

  The noise from a plane's engine is over 140 decibels. However, the sound of a flute is at most a few decibels. Therefore, the sound of ordinary musical instruments cannot harm your health. It has been proven that people who have worked in an environment 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 can't hear and only those who have the same ability can feel. In nature, there is actually sound that is beyond our hearing. In physics, the sound that exceeds 20,000 Hz is called ultrasonic. Dolphins, whales and bats can make such high-frequency sound. It does no harm to health.

  Sound less than 20 Hz is called infrasonic waves. When we move, the air will vibrate. The vibration of air can produce infrasonic waves. As the frequency of infrasonic waves is close to that of people's internal organs, infrasonic wave may cause resonance in human bodies. As a result, people's vision may weaken and internal organs may rupture. However, whether an infrasonic wave can be used as a weapon depends on its intensity. If its intensity is very low, it won’t damage internal organs or a person's health. If the intensity of infrasonic wave exceeds 160 decibels, it is extremely harmful. When wind blows at a force of 3 or 4 over the sea, 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

  C.can be used as deadly weapons.

  D.can improve eyesight.

  41.C 文章开篇以音乐为例,简单介绍了其附加功能,接着详细介绍了不同分贝的声音会产生怎样不同的效果,因而重点在于声音及其效果。故此题选C。

  42.A 第一段明确提到了“it not only moves people but also can shock people”,故此题选A。

  43.D 第二段明确提到了“Once sound exceeds this limit, even beautiful music will become earsplitting noise and harm health.”,故此题选D。

  44.D 第三段明确指出了“there is actually sound that is beyond our hearing”,故此题选D。

  45.C 文章最后一段“infrasonic wave exceeds 160 decibels, it is extremely harmful”和“scien-tists can only produce infrasonic weapons in the lab”两处都提到此意思,故此题选C
