Question

【題目】閱讀下面短文，從下面每小題的A、B、C、D四個選項中選出最佳選項，并在答題卡將相應的字母編號涂黑。
All over the world the need for more laptops and computers increases each year. Networks have been part of our life. Probably everyone with a portable device （移動設備）has once logged on to a public WiFi network without paying for it, while they are having a coffee, on a train, in a shopping mall or at a hotel. However, is this kind of public WiFi network safe?
Some networks are better protected than others because encryption （加密）methods are used. Therefore, they are safer than others. But a survey in 2015 showed that more than 950 million records were not protected, including addresses, emails, birth dates, phone numbers, passwords and so on. These open WiFi networks are really not safe, because it is very easy for hackers （黑客） to break into the operating system and get people's private information.
Most smartphones and laptops, by themselves, search and connect to WiFi networks. They usually prefer a network with a connection that has been used before. Hackers' devices are able to record these searches and look like the trusted WiFi networks. When these smartphones and laptops log on to the networks which are not real, hackers can easily steal their private information.
So next time, when we want to use our laptops or our smartphones in public places which offer free WiFi networks, please think it twice or take safe measures before using them.
（1）Why do people like to go log on to a public WiFi network?
A.Because it can provide useful information.

D.Because it is safe.
（2）We can learn from the passage that .
A.not all the public WiFi networks are safe
B.none of the public WiFi networks is safe
C.in 2015more than 950million records were protected
D.there is no way to protect our private information
（3）Hackers would probably get the following EXCEPT when we connect our laptops or smartphones to a public WiFi network.
A.our birth dates
B.our passwords
C.our phone numbers
D.our smartphones
（4）Which of the following can be the best title of this passage?
A.Don't Use Public WiFi Networks

Answer 1

【答案】
（1）C
（2）A
（3）D
（4）B
【解析】短文大意：本文講述了公共wifi網(wǎng)絡的安全問題. 越來越多的人使用移動設備，因此他們可以隨時隨地地使用，隨時連接上公共wifi，然而網(wǎng)絡安全也需重視. 黑客能夠得知用戶經(jīng)常連接的網(wǎng)點，用相似的名稱"偽裝"成用戶經(jīng)常連接的網(wǎng)絡，盜取用戶信息﹣﹣包括地址、郵箱、生日、電話號碼、密碼等，損害用戶的利益.
（1） C 推理判斷題. 由第一段句子Probably everyone with a portable device （移動設備）has once logged on to a public WiFi network without paying for it，中的without paying for it可以推測出原因﹣﹣因為免費. 因此答案為C.
（2）A 推理判斷題. B項可以從第二段的第一句和第二句話Some networks are better protected than others because encryption （加密）methods are used及Therefore，they are safer than others得出，有一些是安全的，因為加密了. C項也可從句子But a survey in 2015 showed that more than 950 million records were not protected，得知是錯誤的，是沒有被保護，而不是"被保護了"；D項可從第二段第一句了解保護措施Some networks are better protected than others because encryption （加密）methods are used，加密可以保護網(wǎng)絡安全. 故只有A的說法正確. 故選A。
（3）D 細節(jié)理解題. 根據(jù)題目要求可知，本題要求解答黑客可以獲取哪些信息，這個內(nèi)容可以在原文第二段找到，…including addresses，emails，birth dales，phone numbers，passwords and so on. D項不符合，D項不屬于信息的范疇. 故選D。
（4）B 內(nèi)容歸納題. 概括本文內(nèi)容可知，全文主要講的是公共網(wǎng)絡的安全問題，同義的句子為B﹣﹣為什么公共wifi可能很危險？因此答案為B。
