五、阅读理解
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(理论) 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 a built-in system a bit like BDS and this helps them find their way back to their hives(蜂巢). 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 seemed at first. The important thing about bees is that most of the crops in many countries are pollinated by them. Without bees, crops can’t continue to grow.
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.
24．What might be caused by mobiles according to Paragraph 1
A．Poor listening.
B．Forest fires.
C．The disappearance of bees.
D．Terrible toothaches.
25．What does the theory in the passage say
A．Bees have BDS inside their bodies.
B．Mobiles have an influence on bees’ hives.
C．The radiation makes bees unable to fly.
D．The radiation makes bees lose their way home.
26．The underlined word “pollinated” in Paragraph 3 probably means “________” in Chinese.
A．授粉 B．污染 C．啃食 D．催熟
27．The writer writes this passage to ________.
A．call on people to help beekeepers
B．show how a bee’s built-in system works
C．ask people to stop using mobiles right away
D．warn people of the possible harm mobiles do to bees
