Question

【題目】Last fall，beekeepers from states with warm climates began to report a sudden loss of honey bees.Losses were reported in twentyfour states and spread to Canada.Today，some beekeepers say thirty percent to ninety percent of their honey bees are gone.Food price could go up as a result.And some beekeeping businesses have failed.

Many kinds of plants，trees and grasses need bees to pollinate them.Bees gather nectar from flowers during this process.The liquid gives them food and material to make honey.As the bees land on flowers，their bodies pick up and drop off particles of pollen(花粉)．Most flowering plants need pollination to reproduce.

Honey bees can die during the winter.But few dead bees have been found this time.Instead，the bees seem to have disappeared.Experts call the condition “colony collapse disorder”．

Agriculture Department official Caird Rexroad said the colony collapse disorder threatens about fifteen billion dollars worth of the country's farm economy.Mr.Rexroad commented at a hearing of a House of Representatives agriculture subcommittee.

Mr.Rexroad said the cause of the sudden loss of bees was not clear.The number of honey bees had already fallen before the colony collapse disorder began.

Experts say the varroa mite is at least partly responsible for the earlier decrease in honey bees.The mite is a tiny creature that feeds on honey bees.It may play a part in colony collapse disorder by carrying bee viruses.Or the problem may be caused by other disease and weather conditions.

Diana CoxFoster of Pennsylvania State University is part of the scientific group.Ms.CoxFoster says the nation needs honey bees that can defnd themselves better against disease and insects.The recent mapping of most of the honey bees' genes offers the hope of a stronger honey bee some day.

Answer 1

【答案】

【1】C

【2】A

【3】D

【解析】

試題分析:本文是一篇說(shuō)明文，介紹了美國(guó)蜜蜂蜂群離奇消失，給科學(xué)家提出了難題。

【1】C細(xì)節(jié)理解題。根據(jù)第一段“.Losses were reported in twenty-four states …h(huán)oney bees are gone.”可知，很多蜜蜂都無(wú)緣無(wú)故地消失不見(jiàn)了。故選C。

【2】A判斷推理題。根據(jù)第三段可知，蜜蜂是在冬季死亡， 但是這個(gè)時(shí)間很少會(huì)找到蜜蜂的尸體，這就似乎看起來(lái)蜜蜂離奇消失了，專家們霸這現(xiàn)象稱為蜂群消失病。所以推測(cè)蜜蜂在寒冷的天氣里死亡是正常的。可知選A。

【3】D主旨大意題。根據(jù)全文內(nèi)容可知，全文的主旨是說(shuō)蜜蜂離奇消失，科學(xué)家們作出了種種推測(cè)，但是還是沒(méi)有一個(gè)明確的答案。只有選項(xiàng)D符合題意。
