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(杜鵑),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(島嶼巨型化)",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(多樣化) of the cuckoo bees'hosts and also to understand their evolution across the islands.

解答 32.A 細(xì)節(jié)理解題,根據(jù)第一段The behavior is usually seen in cuckoos(杜鵑),so the new species has been named the"cuckoo bee".可知這個(gè)蜜蜂叫"杜鵑蜂"是因?yàn)樗且远霹N的生活方式存活下來(lái),故選A.
33.C 詞義猜測(cè)題,根據(jù)第一段Pirate bees!Scientists have discovered a new species of bee that survives by capturing hives(蜂房) made by other species.可知科學(xué)家發(fā)現(xiàn)了一種新的蜜蜂,他們?cè)诜涑怖锊东@其他物種,故選C.
34.A 細(xì)節(jié)理解題,根據(jù)倒數(shù)第二段Physically,the cuckoo bees look like zebra,featuring mostly black-and-white patterns.可知杜鵑蜜蜂看起來(lái)像斑馬,故選A.
35.D 細(xì)節(jié)理解題根據(jù)倒數(shù)第二段 Engel and Straka believe the large size of most of the cuckoo bee species is the result of"island gigantism(島嶼巨型化)",a phenomenon where a species can grow at an extreme rate when separated from the rest of its kind.可知大多數(shù)杜鵑蜜蜂看起來(lái)更大的真正原因是它們與其他種類分離,故選D.
