Mobile phones are one of the most useful inventions of the last 50 years, but not everything that is

Passage 14【2020 •山东日照】

 

 

Mobile phones are one of the most useful inventions of the last 50 years, but not everything that is said about them is good. Mobiles are often believed to be the cause of a number of things from poor eyesight and headaches to house fires. There's even one theory that mobile phones should be responsible for the disappearance of bees!
The theory is that the radiation (辐射) given off by mobile phones does great harm to bees' navigation systems (导航系统). Bees have built-in system a bit like GPS and this helps them find their way back to their hives. But recently, thousands of bees have failed to find their way home. It is believed they are dying far from their hives.
The problem was first noticed by beekeepers in America and is a lot more serious than it at first seems. The important thing about bees is that most of the crops in many countries of the world are pollinated by them. Without bees, the crops can't continue to grow. Many beekeepers in Europe have reported losing between 50 and 70 percent of their bees. Jim Piper, London beekeeper, said to the reporter, "My business is becoming worse. Twenty-nine of my forty hives are now empty."
Nobody knows for sure whether the theory is true or not, but it's a fact that bees are disappearing in very large numbers. And we can't manage without them. Einstein said that if all our bees disappeared, man would only live for four more years! If the mobile phone theory is correct, we need to do something about it right now—before it's too late.

本文介绍了由于手机的辐射对蜜蜂的导航系统有害,导致很多蜜蜂找不到回家的路。
41.C【解析】细节理解题。根据“There's even one theory that mobile phones should be responsible for the disappearance of bees!”可知,蜜蜂的消失可能是由手机导致的,故选C。
42.D【解析】推理判断题。根据“The theory is that the radiation (辐射) given off by mobile phones does great harm to bees' navigation systems (导航系统). ”和“ But recently, thousands of bees have failed to find their way home.”可知,这个理论说手机的辐射让蜜蜂找不到回家的路,故选D。
43.A【解析】词义猜测题。pollinate授粉,pollute污染 ,gnaw啃食,ripen催熟。根据“Without bees, the crops can't continue to grow.”可知,没有蜜蜂,庄稼无法继续生长,因此蜜蜂帮助庄稼授粉,故选A。
44.C【解析】主旨大意题。根据“The problem was first noticed by beekeepers in America and is a lot more serious than it at first seems. ”可知,第三段主要告诉我们,蜜蜂的消失是一个严重的问题,故选B。
45.D【解析】推理判断题。根据“There's even one theory that mobile phones should be responsible for the disappearance of bees!”可知,本文警告人们手机对蜜蜂可能造成的伤害,故选D。
