雅思阅读练习题之二(2)
很好的练习题哦！
Answer keys
1. 第一段“Now a study suggests that a popular secondary security measure provides little additional protection.”似与问题文字很接近，但是原文中a popular secondary security measure是指特定的一个措施，而非泛指所有secondary security measure。原文没有其它secondary security measure安全有效性的内容。故应选择NG。
2. 见第4、5段内容。第四段 “But the researchers had secretly withdrawn the images.”即研究人员撤下了图形，第五段“Only two chose not to log on, citing security concerns.”，有两个人因为安全考虑未进入。
3. T 见第6段。
4. F 见第11、14段。
5. F 见第11段“Bank of America was among the first to adopt it”，可见首批采用图形识别软件的银行并非Bank of America一家。
6. A financial institution 见第二段。
7. (their) passwords 见第三段。
8. less convenience 见第十段。
9. identity 见第八、十段。
10. Silicon Valley 见第十一段。
11. easy to use 见第十二段。
12. site maintenance message 见第十三段“When respondents logged in during the study, they saw a site maintenance message on the screen where their image and phrases should have been pictured.”
13. 4 分别见第十段的“download new security software”和“hardware devices that feed them PIN codes”，第十五段的“a small software program, called a cookie”，以及本文提到的site-authentication images。
