21、most useful inventions of the last 50 years, but not everything that is said about them is good.

22、en off by mobile phones. Bees have a built-in system a bit like GPS and this helps them find their way back to their hive. But recently, thousands of bees have failed to find their way home. 2The problem was first noticed by beekeepers in America and is a lot more complicated than it at first seems.
23、 The important thing about bees is that most of the crops in many countries of the world are pollinated (授粉) by them. 3Many beekeepers in America and Europe have reported losing between 50 and 70 percent of their bees.

27、 【解析】选G。 从空前的Mobile phones are frequently blamed for a number of things, from thumb injuries and headaches to house fires. 及下段第一句中的关键词The theory可知, G项(One theory even blames mobile phones for the disappearance of bees)符合语境, 故选G。2. 【解析】选D。由上句的“最近, 数千只蜜蜂找不到回家的路”可以得出结论“人们认为它们即将在离蜂巢很远的地方死去。”故选D。 3. 【解析】
28、选E。 由上句The important thing about bees is that most of the crops in many countries of the world are pollinated by them. 可知, 蜜蜂重要的作用就是授粉, 下文则谈蜜蜂消失给农业造成的影响, 即没有蜜蜂, 庄稼就不能继续生长。故选E。4. 【解析】选B。 本题的填入内容与空后的However, the fact that bees are disappearing in very large numbers is real. “然而蜜蜂正在大量消失这一事实却是真的。”为转折关系。However在上下两句中表示转折, 是理解前后两句关系的关键词。5. 【解析】选F。 由上句Einstein said that if all our bees disappeared, man would only live for four more years!及下句“If the mobile phone theory is correct, we need to do something about it immediatelybefore its too late. ”可知, 科学家必须趁着为时不晚马上采取行动, 需要世界上最优秀的科学家对这种情况做出评估。故选F。
