6.Flies are buzzing.Most people think they are dirty and annoying.But in Bryan Lessard's eyes,flies are beautiful insects with great abilities.
Lessard is a researcher at Australia's CSIRO.He is an expert on flies.According to Lessard,more than 159,000 types of flies have been found around the world.The number forms 10-15 percent of all the known animals on Earth!
Shocked?The truth is that you can never get away from flies,Lessard says.If you are a chocolate lover,you really should thank flies.Because there would be no chocolate without them!
A tiny kind of fly is the only known pollinator (授粉者) of the flower of the cocoa plant.These special flies are native to countries that are rich in cocoa,such as Brazil and Ecuador.They play a great role in the world's big sales of chocolates.Flies,as well as some other insects,also pollinate Australia's tea trees.Flies are a huge driver of the economy,but we take them for granted.
Flies can also be useful in other cool ways.Take black soldier flies for example.Scientists in Australia,India and US are turning black soldier fly larvae (幼蟲) into a nutritious feed for livestock(家畜).The larvae are 45 percent protein.They find that chickens fed on the larvae grow larger,and don't experience any harmful side effects.As well as that,Chinese researchers from Wuhan's Huazhong Agricultural University have made oil from the black soldier fly larvae and turned the liquid into a form of biodiesel (生物柴油).So someday our cars could be powered by flies!

分析 這是一篇社會文化類閱讀,作者首先引用Lessard的觀點:蒼蠅對人們還是有用處的,并舉例說明有些蒼蠅是唯一已知的可可植物的授粉者,有些是家畜的營養(yǎng)飼料,更有中國科學(xué)家從蠅幼蟲中獲取了油并把這種液體轉(zhuǎn)變成一種生物柴油.充分說明了蒼蠅對我們的用處.
解答 32.A 推理判斷題.根據(jù)文中第一段中的But in Bryan Lessard's eyes,flies are beautiful insects with great abilities.以及第三段中If you are a chocolate lover,you really should thank flies.可得在Lessard眼中,蒼蠅是有著很多功能的美麗的昆蟲,比如巧克力的制作就離不開它.可知:蒼蠅對人們還是有用處的,故選A.
33.B 細節(jié)理解題.根據(jù)文中第四段中的A tiny kind of fly is the only known pollinator (授粉者) of the flower of the cocoa plant.可得這種小型的蒼蠅是唯一已知的可可植物的授粉者,再結(jié)合題中選項,故選B.
34.D 細節(jié)理解題.根據(jù)文中最后一段中的Chinese researchers from Wuhan's Huazhong Agricultural University have made oil from the black soldier fly larvae and turned the liquid into a form of biodiesel (生物柴油).可得,中國武漢的華中農(nóng)業(yè)大學(xué)的研究人員從蠅幼蟲中獲取了油并把這種液體轉(zhuǎn)變成一種生物柴油.故選D.
35.A 推理判斷題.根據(jù)文中最后一段中的Scientists in Australia,India and US are turning black soldier fly larvae (幼蟲) into a nutritious feed for livestock(家畜).可得來自澳大利亞,印度和美國的科學(xué)家把蠅幼蟲變成了家畜的營養(yǎng)飼料,所以可知蠅幼蟲是家畜的很好的飼料,故選A.
點評 這是一篇社會文化類閱讀,題目涉及多到細節(jié)理解題,做題時結(jié)合原文和題目有針對性找出相關(guān)語句進行仔細分析,結(jié)合選項選出正確答案.推理判斷也是要在抓住關(guān)鍵句子的基礎(chǔ)上合理的分析才能得出正確的答案.
