篇章分析
本文是一篇說明文,講述了短信服務中的垃圾短信問題。文章第一段介紹了短信服務正成為一種被廣為使用的信息交流服務。第二段提出了垃圾短信問題,并分析了垃圾短信為何惹人生厭,第三段繼續分析垃圾短信侵犯人們的隱私,最后一段講述了對短信服務商來說垃圾短信也不是一件好事。
答案及解析
51.【答案】D
【題型】細節題
【解析】題干意為“什么為短信服務創造了一個良好條件?”從文章第一段第二句話可以看出是“the development of mobile communications technology and service”即移動交流技術和服務的發展為短信服務創造了有利條件,因此正確答案為D。
52.【答案】B
【題型】細節題
【解析】題干意為“通過MMS,短信息可以在除下面什么以外的設備上傳送?”從文章第一段第四句話可以看出可以在手機和電腦以及手機之間傳送,文章并沒有提到在電腦之間發短信息,因此正確答案為B。
53.【答案】A
【題型】推理題
【解析】題干意為“人們有時并不喜歡短信服務是因為什么?”文章第二段談到了這個問題,但我們需要將四個答案與原文逐一對比、逐一排除。B短信服務侵犯了人們的隱私,而從第二段第二句話可以看出是垃圾短信嚴重侵犯了用戶的隱私,因此排除B。同樣從最后一句話可以看出是發垃圾短信的人沒有考慮人們是否需要垃圾短信,沒有得到人們的允許就發垃圾短信,可以排除C、D。正確答案為A。
54.【答案】C
【題型】推理題
【解析】題干意為“MMS可能會侵犯人們的隱私是因為什么?”從文章第三段最后一句話可以看出MMS。促使網上的不健康信息能夠從電腦傳到手機上,從而擴大了垃圾短信的范圍和影響,綜合考慮這一段話上下文的含義,我們可以判斷正確答案為C。
55.【答案】B
【題型】主旨題
【解析】題干意為“從這篇文章我們可以知道什么?”A人們應該拒絕垃圾短信,B短信服務應該想辦法除掉垃圾短信,C多媒體服務不應該允許人們從網上給手機發信息,D短信服務從垃圾短信中獲益,A、C、D都不是文章想說明的觀點,B最貼切文意。故選B。
