1.細節(jié)理解題根據(jù)第二段倒數(shù)第二句"and her typing style was analyzed to make sure she was who she said she was: Did she enter her student number at the same speed as she had in the past? "可從本句得知監(jiān)控Jennifer的原因是為了確保她不作弊。故選D,就是不誠實的行為。屬于上下義重現(xiàn)。
2.猜詞題根據(jù)a key to encourage 以及下一句的 the technology 可以知道答案。cutting edge與key是并列關(guān)系,同時二者都可以做到鼓勵誠實行為。前面this所指代的為上文中提到的防作弊科學技術(shù),由此得知cutting edge應該為advanced technique。
3.細節(jié)理解題根據(jù)第三段 Only with solid measures against cheating, experts say, can Internet universities show that their exams and diplomas are valid -that students haven't just searched the Internet to get the right answers.可以得出答案。屬于原詞重現(xiàn)。本解析為學科網(wǎng)名師解析團隊原創(chuàng),授權(quán)學科網(wǎng)獨家使用,如有盜用,依法追責!
4.細節(jié)理解題根據(jù)最后一段的第一句" Other programs can produce unique exams by drawing on a large list of questions and can recognize possible cheaters by analyzing whether difficult test questions are answered at the same speed as easy ones. "可知正確選項為A。此題易錯選BD。
其實選項A包含了BD選項內(nèi)容。通過生成大量的有難也有易的問題,然后通過比較答題速度。屬于原詞重現(xiàn)。
5.主旨大意標題題文章主題句位于第三段第一句"In the battle against cheating, this is the cutting edge and a key to encourage honesty in the booming field of online education."可得知本文主要討論網(wǎng)絡課程的防作弊問題,故選C。此外,文章多次出現(xiàn)cheating,屬于原詞重現(xiàn)。
