[语篇解读] 作者用诙谐的语气质问WiFi,这呈现了现代人的一种通病,那就是对无线网络的依赖。
1.A.Nowthat B.Onlyif
C.ThoughD.When
根据语境可知,虽然(Though)作者知道WiFi帮助了自己,但是正是WiFi的特殊作用让作者在做事情的时候会分心。
2.A.praisedB.increased
C.focusedD.divided
参见上题解析。
3.A.keepinB.bringback
C.approveofD.giveup

bringback“使回忆起,使想起”;
approveof“同意,赞成”;
giveup“放弃”。
4.A.drawingB.pushing
C.forcingD.observing
根据语境可知,此处形象生动地表现了作者不能抗拒WiFi对自己的吸引。
draw“吸引”符合语境。
push“推,催促”;
force“强迫,迫使”;

5.A.spaceB.soul
C.societyD.workplace

strict“严格的”;
generous“慷慨的”;
busy“繁忙的”。
8.A.thoughtsB.eyes
C.exitsD.doors
此处表示人们将WiFi的作用扩大化,不仅仅满足于其作为窗口的作用,而是将所有的“门(doors)”打开迎接WiFi。
某种程度上而言,door是window的“升级版”。

C.routineD.phenomenon
结合下文中的“anillness”可知,作者疑惑的是自己和其他人对WiFi如此依赖的现象是否是一种病(disease)。
inspiration“灵感”;

如果对WiFi的情感是一种依赖的话,WiFi能保证与作者一生都亲密无间吗?
