American universities are rushing towards a wireless future. They are installing networks that let students and teachers surf the Internet from laptop computers(笔记本电脑). But professors say the technology poses a growing【C1】______: Retaining their students’ attention.
In a classroom at American University in Washington D.C., the benefits and【C2】______of the new wireless work were on display. From the back row of a lecture hall, more than a dozen laptop screens were【C3】______. As Professor Jay Mallek lectured on the finer points of an office budget, many students went online to surf the Internet. Students write quick emails and send instant messages. A young man shows an amusing email to the women next to him, and then switches over to read the online edition of The Wall Street Journal. Distraction is nothing【C4】______. As long as there have been schools, students have whispered, passed notes and even gazed out the window and daydreamed. But the【C5】______of the laptop has introduced new opportunities for distraction, and wireless introduces an even【C6】______range of distraction.
This is【C7】______annoying for law professors, many of whom still live in the world of paper. "This is something that hurts the students themselves," said Ian Ayres, professor at Yale Law School, who【C8】______the Internet’s entry into the classroom. However, Professor Mallek sees it【C9】______. He said the benefits of the technology outweigh(胜过)the problems. He suggested that it might even be making him a better teacher. He takes the【C10】______of losing his students to email and online newspapers as a challenge to keep lectures lively and interesting.
A)visible I)new
B)threat J)demonstrates
C)possible K)larger
D)opposes L)differently
E)obstacle M)challenge
F)especially N)arrival
G)broader O)advantages
H)drawbacks [br] 【C10】
选项
答案
B
解析
根据空前的定冠词the可知,此处应填一个名词。of losing his students是用来修饰空格处所填名词的,由此可以判断该名词应该是表否定、消极意义的。在备选的名词中表达此意的词有B)threat(威胁,恐吓),E)obstacle(障碍,绊脚石)可选。但对于老师来说,学生的注意力转移到emil或在线报纸不是一种障碍,而是一种成胁,故选B)threat。
