临床上存在不可察觉的鼻音异常的疾病是

A.急慢性鼻炎

B.鼻息肉

C.鼻肿瘤

D.萎缩性鼻炎

E.腭裂

答案

参考答案:D

解析:萎缩性鼻炎常伴有咽部软组织及咽侧索不同程度的萎缩,发声时咽侧索向中线内移减弱,因而不同程度地影响咽腔闭合所致。急慢性鼻炎、鼻息肉、鼻肿瘤等阻塞性病变时,发声时即严重影响甚至完全没有鼻腔的共鸣作用,语音的质量即改变,音显平实不悦耳,呈闭塞性鼻音。腭裂呈开放性鼻音。

A university math tutor has discovered the science behind “singledom”, finding that our chances of finding the perfect partner are just 1 in 285,000. Peter Backus, a tutor at the University of Warwick, published his “Why I Don’t Have a Girlfriend” paper after a three-year love drought.

His unconventional study uses a famous math formula called The Drake Equation(德雷克等式), which was first used to estimate the existence of extra-terrestrial(地球以外) life.

The results don't look promising for British singles. 30-year-old Mr. Backus found that out of the 30 million women in the UK, only 26 would be suitable girlfriends for him.

The dull equation takes into account the number of women aged 24 to 34, living in his home city of London, and who are single, meaning his chances of meeting his dream woman on a night out are slim.

The economics expert said: “There are 26 women in London with whom I might have a wonderful relationship. So, on a given night out in London there is a 0.0000034% chance of meeting one of these special people. That’s a 1 in 285,000 chance, so it’s not great.”

The puzzling Drake equation reads: N =" R*" x Fp x Ne x Fi x Fc x L, and helped pioneering scientist Professor Drake to predict that there could be 10,000 civilizations in our galaxy.

Mr. Backus simply replaced the original equation with his own criteria for a dream date, which included the percentage of women likely to find him attractive, and the number of girls aged 24-34 in London. He said: “The research may sound depressing to people looking for love, but the good news for singles is, it’s probably not your fault!”

56. Mr. Backus’ discovery in this passage is mainly concerned about ______.

A. whether there exists life out of our planet

58. What can we learn from the first paragraph?

A. Mr. Backus’ major research field is “singledom”.

B. Mr. Backus found a girlfriend three years ago.

C. Mr. Backus’ new thesis will surely be well received.

D. Mr. Backus has been searching for love for long.

59. By “the good news for singles” in the last sentence, Mr. Backus probably mean _____.

A. you don’t have to blame yourself for remaining single  

B. maybe the discovery is not reliable at all

D. there might be more dream date out of London

60. Which of the following statements is true?

A. This passage could be published in a scientific magazine.

B. The passage intends to prove there are other civilizations.

C. The passage writer doesn’t really understand the Drake equation.

D. Most women in London are not suitable for university teachers.
