B. Bees are important for food crops.
C.
Bees give us a lot of delicious honey.
D. Cherry trees are pollinated by bees.
答案 B
解析 段落大意题。根据第二段的第二、四句可知,蜜蜂可以帮助植物授粉;在美国,养蜂人养的数百万只蜜蜂飞来飞去为粮食作物做着这种重要的授粉工作。因此选择B。
5.Bees are hard to study because
.
A. they move around too much
B. new bees soon replace all the bees studied by researchers
C. they are too tiny
D. they never return to hives
答案 A
解析 细节理解题。根据第四段中的“However, bees are hard to study. Most die away from the hive”及Pettis的话“It isn't like studying a large animal like a cow that doesn't move around much and is easy to find out in the cow field”可知,研究蜜蜂很难是因为它们活动得太多。
6.What could cause so many bees to die?
A. Poisons to kill birds.
B. Eating too much.
C. Large insects.
D. Some virus.
答案 D
解析 细节理解题。根据最后一段中的“A virus or bacteria could also be doing the killing”可知,某种病毒可能是蜜蜂大量死亡的原因,故选D;由最后一段中的“They could be sick because of poisons widely used to kill insects”可知,蜜蜂的死亡也可能是由可广泛用来杀死昆虫的毒药引起的,故A项说法不正确。
