a field about which humans had a great deal to learn.It is impossible to know today just what our Stone Age ancestors knew about plants, but from what we can observe of preindustrial societies that still exist, a detailed learning of plants and their properties must be extremely ancient.This is logical.Plants are the basis of the food pyramid for all living things, even for other plants.They have always been important to the benefit of peoples, not only for food, but also for clothing, weapons, tools, dyes, medicines, shelter, and a great many other purposes.Tribes living today in the jungles of the Amazon recognize hundreds of plants and know many properties of each.To them botany, as such, has no name and is probably not even recognized as a special branch of “knowledge” at all.Unfortunately, the more industrialized we become the farther away we move from direct contact with plants, and the less definite our knowledge, and few people will fail to recognize a rose, and apple, or an orchid.When our ancestors, living in the Middle East about 10,000 years ago, discovered that certain grasses could be harvested and their seeds planted for richer harvests the next season, the first great step in a new association (联系) of plants and humans was taken.Grains were discovered and from them flowed the wonder of agriculture: cultivated crops.From then on, humans would increasingly take their living from the controlled production of a few plants, rather than getting a little here and a little there from many varieties that grew wild and the accumulated (积累) knowledge of tens of thousands of years of experience and close contact with plants in the wild would begin to fade away.1Which of the following statements is TRUE?AEarly humans knew nothing about plants.BEarly humans probably had extensive knowledge of plants.CEarly humans had little knowledge of plants.DEarly humans did not enjoy the study of botany.解析:选B细节理解题。由第一段第三句的前半部分可知B项正确。2In Paragraph 1 the underlined word “properties” refers to_.Athe belongings of early humansBthe wealth of ancient peopleCthe characteristics or qualities of plantsDBoth B and C 解析:选C词义猜测题。全文出现property的地方有两处,除了第一段之外,在第二段倒数第二句话还能找到。观察其搭配,可发现这个词两处都与plant联用,可猜出其意思与人类无关,故选C项。3Tribes living today in the jungle of the Amazon_.Adont know anything about plantsBrecognize botany as a branch of scienceCfirst give the name of botanyDare experts of plants解析:选D细节理解题。从第二段看出,亚马孙丛林中的部落人能认识数百种植物,并熟悉它们的属性。他们不知道什么叫“植物学”,这些知识只是想当然的事,甚至不纳入“知识”范畴。故选D项。4According to the passage, what was the first great step toward the practice of agriculture?AThe invention of agricultural implements and machinery.BThe development of a system of names for plants.CThe discovery of grasses that could be harvested and replanted.DThe changing diets of early humans.解析:选C细节理解题。从最后一段第一句中可以得出答案。BThe Japanese like parties.From ancient times, a party becomes enlivened (活泼) when someone starts singing and others keep applauding.Having such a custom, the Japanese can easily sing in front of others without feeling embarrassed.This seems to be one of the reasons that karaoke has been largely accepted in Japanese society.It is now widely recognized that the use of karaoke started at a snack bar in Kobe City, one of the three biggest cities in Japan.It is said that when a guitarist could not come to perform at the bar due to illness, the owner of the bar prepared tapes of accompaniment recordings, and people enjoyed singing to the tapes.It was at that time that karaoke appeared.Holding a microphone and singing a song to the accompaniment of an “orchestra (管弦乐队)”, you can feel like a professional singer.For soldiers living in a stressful society, there is no other entertainment activity that can make them feel so refreshed.It is a typical way to relax for Japanese businessmen.They use it to take away their stress after work.However, there is an obstacle to this: since most Japanese houses are still made of wood, it would be very annoying to the neighbors to sing into a microphone at night.Seizing upon the opportunity, businessmen created the karaoke box, a roadside facility containing karaoke equipment.Karaoke boxes are soundproofed rooms, closed with a door, placed on roadsides where people can sing.The first “Karaoke box” was placed in a rice camp in the countryside in 1984.It was built from a converted freight car (改装的货运车)Now, the karaoke boom has even spread abroad and it has also been attracting the attention of the countries trying to improve their literacy rate (识字率) as a good educational tool.5According to the text, we can learn that karaoke _.Aoriginated from the biggest city of JapanBoriginated in the form of singing to tapesCcan help you achieve the level of professional singersDfirst appeared in the army to relieve stress for soldiers解析:选B细节理解题。根据第二段可知卡拉OK起源于日本三个大城市之一,Kobe的一间小零食店,这家小店因为吉他手生病不能演奏,店主就录制了吉他手的乐曲,歌手唱歌时播放录制的音乐,因此可知A项错误,B项正确。根据第三段“feel like a professional singer”可知卡拉OK让你的歌声听起来像专业歌手的歌声,并不能让你真正达到专业歌手水平,故排除C。文章第三段提到卡拉OK是士兵缓解压力的不二方式,但卡拉OK并非诞生于军营,故排除D。6The underlined word “soundproofed” in Paragraph 4 most probably means “_”Arecording sounds repeatedlyBreceiving sound signalsCmaking sound more clearDstopping sound from being heard outside解析:选D词义猜测题。根据画线单词前后语境可知由于日本的房子大都是木房子,隔音效果
