【文章內(nèi)容簡介】 t like using “ Konniqiwa” as a greeting for the whole day C． people don’ t need to be polite to their colse friends D． Japanese people are very friendly to each other 答案 B 解析 理解推斷題。根據(jù)第二段的 “ ...I am sure you wouldn’ t like greeting people with a ‘ Good day’ at any time, and neither do Japanese like saying ‘ Konniqiwa’ when they want to say ‘ Hello’ ． ” 可知作者認(rèn)為在日本，人們不會(huì)喜歡一天到晚用 Konniqiwa 來跟別人打招呼。 39． What does the underlined word “ invariably” in the last paragraph mean? A． Probably. B． Always. C． Sometimes. D． Likely. 答案 B 解析 詞義猜測題。根據(jù)第三段的 “ because one hardly ever uses ‘ Good morning’ or ‘ Good afternoon’ or ‘ Good evening’ right after picking up the phone.” 可知人們拿起電話的時(shí)候，通常不會(huì)分早、中、晚問候，只是說 Moshi, Moshi, 由此可推斷作者是想表達(dá)接電話時(shí)、問候別人時(shí)總是用甜美而古老的 “ Hello” 。 B An Australian based scientist announced yesterday he had made a step forward in forensic (用于法庭的 ) DNA testing so that an individual can be identified by a single cell. Ian Findlay， from the Australian Genome Research Facility at the University of Queensland，said current DNA testing required 200 to 500 cells to gain a similar level of accuracy.“ What we have done has brought that down to one cell， ” said after releasing details of his DNA testing technique at a Sydney conference. The technology could allow investigators to pick up DNA identifies from plastic cards and even build up a plete history of the people who have handled a paper document. “ You’ d have to wear a space suit to stop yourself from leaving can identify cells on the paper， so you can work out where it came from and who touched it， ” he said. The technique could also be used to trace the thrower of a punch from cells left behind on the skin of their the wearing of latex gloves would not help： small cells can pass through the gloves， and the constant flow of geic material given off by the human body would leave further evidence. “ We gained a skin cell from a document dating back 30 years and managed to gain a DNA evidence can remain fresh for decades， perhaps even centuries， ” said.“ The potential for this technology to solve unsolved crimes is great， ” he added. But ， named scientist of the year in 1998 by the European Society of Human Geics， said the new testing needed to be scientifically validated， which would take up to five years. He said， “ There are serious consequences taking on technologies too public has to be sure that they have the utmost confidence in the security and court systems.” 40． The main advantage of the new technology is that_____________________________ __________________________________________. A． a single cell can identify an individual B． it has brought down the cost of DNA testing C． a higher level of accuracy can be acquired with a single cell D． it needs less than 200 cells to gain a certain level of accuracy 答案 A 解析 細(xì) 節(jié)理解題。由第二段的最后一句可知 A項(xiàng)正確。 41． The underlined word “ validated” in the seventh paragraph means________. A confirmed B． imagined C． supposed D． criticized 答案 A 解析 詞義猜測題。倒數(shù)第二段的大意為：這項(xiàng)新的測試要科學(xué)地驗(yàn)證、確認(rèn) (confirm)至少還需要 5 年的時(shí)間。 42． According to Ian Findlay， the new technology can_________________________ ______________________________________________. A． help to keep DNA evidence fresh for decades and even centuries B． make the process of DNA testing much more simplified C． help to pick up DNA identities more easily D． be widely used in five years at most 答案 C 解析 細(xì)節(jié)推斷題。倒數(shù)第三段說明新技術(shù)使 DNA采集變得更容易了。 43． The last paragraph suggests that________. A． the immediate adopting of the technology may cause mistakes B． the public have acknowledged the new testing technology C． it is safe to put the new technology into use now D． is quite sure of his new technology 答案 A 解析 段落主旨題。由最后一段可知過早地采納這種技術(shù)可能會(huì)造成錯(cuò)誤，公眾必須確信他們?cè)诎踩退痉w系上擁有最可靠的證據(jù)。 C Edmund Jackson, who is 83 years old now, was injured as a gunner in World War Ⅱ on August 7, 1944. The 20 year old jumped out of the plane and spent 32 days hiding from the enemies in Yugoslavia. The history in Jackson’ s head and the stories of other veterans (退伍軍 人 ) are being collected and will be put in a new series of schoolbooks by the American Veterans Institute. The American Veterans Institute hopes to give the books to schools to get students from three year old to seventh grade more interested in history by offering stories with places, dates and facts. “ I wouldn’ t want to go through it again, but I wouldn’ t have missed it for anything， ” Jackson said. “ It’ s important f
