3.Do you know what is scarier than bees?Pirate bees!Scientists have discovered a new species of bee that survives by capturing hives(蜂房) made by other species.The behavior is usually seen in cuckoos(杜鹃),so the new species has been named the"cuckoo bee".Discovered by Dr.Jakub Straka of Charles University in Prague,and Dr.Michael S.Engel of the University of Kansas,the cuckoo bee was found during a journey to the Republic of Cape Verde is an island chain off the western coast of Africa.Cape Verde is an island that has not been visited before by scientists.Scientists believe the area may be home to a lot of undiscovered species.
According to Straka and Engel's report,the cuckoo bee enters a hive secretly.While the host is out collecting pollen(花粉),the female cuckoo bee enters the hive and lays her eggs on top of the host's.The cuckoo bee eggs hatch more quickly than the other eggs.Then,when they come out of their eggs,the newborn cuckoo bees immediately kill all of the host's eggs and young,and then eat all the stored food.Eventually,they gain control of the hive and live off its resources.
Physically,the cuckoo bees look like zebra,featuring mostly black-and-white patterns.Also,they are mostly quite large.But one species was only 5mm long,which is actually quite small for a bee.Engel and Straka believe the large size of most of the cuckoo bee species is the result of"island gigantism(岛屿巨型化)",a phenomenon where a species can grow at an extreme rate when separated from the rest of its kind.
The researchers are now trying to explore the diversity(多样化) of the cuckoo bees'hosts and also to understand their evolution across the islands.
32.Why is the bee called the"cuckoo bee"?A
A.It survives in a similar way to the cuckoo bird.
B.It looks like the cuckoo bird.
C.Its sound is similar to that of the cuckoo bird.
D.It is from the same island as the cuckoo bird.
33.What does the underlined word"capturing"in the first paragraph probably mean?C
A.Building.
B.Destroying.
C.Controlling.
D.Stealing.
34.The cuckoo beeA.
A.has zebra-like patterns
B.collects pollen before entering a hive
C.kills the host bee after entering a hive
D.enters a hive in a group
35.What is the real reason for most cuckoo bees being larger?D
A.They can get plenty of food from other bees'hives.
B.Their habitat,Cape Verde,has not been polluted.
C.Their hosts are diverse.
D.They are separated from the rest of their kind.
分析 本文属于科教类阅读,作者通过这篇文章向我们介绍了科学家们发现的一种新的蜜蜂--"杜鹃蜂".
解答 32.A 细节理解题,根据第一段The behavior is usually seen in cuckoos(杜鹃),so the new species has been named the"cuckoo bee".可知这个蜜蜂叫"杜鹃蜂"是因为它是以杜鹃的生活方式存活下来,故选A.
33.C 词义猜测题,根据第一段Pirate bees!Scientists have discovered a new species of bee that survives by capturing hives(蜂房) made by other species.可知科学家发现了一种新的蜜蜂,他们在蜂巢里捕获其他物种,故选C.
34.A 细节理解题,根据倒数第二段Physically,the cuckoo bees look like zebra,featuring mostly black-and-white patterns.可知杜鹃蜜蜂看起来像斑马,故选A.
35.D 细节理解题根据倒数第二段 Engel and Straka believe the large size of most of the cuckoo bee species is the result of"island gigantism(岛屿巨型化)",a phenomenon where a species can grow at an extreme rate when separated from the rest of its kind.可知大多数杜鹃蜜蜂看起来更大的真正原因是它们与其他种类分离,故选D.
点评 考查学生的细节理解和推理判断能力.做细节理解题时一定要找到文章中的原句,和题干进行比较,再做出正确选择.在做推理判断题时不要以个人的主观想象代替文章的事实,要根据文章事实进行合乎逻辑的推理判断.
