四、任务型阅读
17．Let me try a wild guess：the system of passwords you use on the Internet﹣ for accessing online banking，e﹣mail，shopping sites，and Renren accounts﹣ is a mess（一团糟）．
You know perfectly well what you ought to be doing for each site you visit，you should be choosing a different，complex sequence of letters，numbers and symbols，and then memorizing it． （That's the first rule of the common knowledge on passwords：never，ever write them down．） But you don't do this，because it's hard for you to remember so many numbers．
So instead，you use the same familiar words for every site﹣your dog's name，the name of your street﹣by adding"123"at the end．Or maybe you do try to follow the rules，and if you're probably getting locked out of your bank account，you began trying to remember the answers to various security questions． （"What was your favourite sport as a child？"）
A recent security breach （安全漏洞） at Yahoo showed that thousands of users' passwords were either "password"， "welcome"， " 123456"or"ninja"．People choose terrible passwords even when more is in danger than their savings．
Password hacking takes many different forms．This is where the length of your password makes an almost unbelievable difference．For a hacker with the computing power to make 1，000 guesses per second，a five﹣letter，purely random，all﹣lower﹣case password，such as "fpqzy"，would take three and three quarters hours to crack．Increase the number of letters to 20，and the cracking time increases it's 6.5 thousand trillion centuries．
If you think you've got a clever system for coming up with passwords，the chances are that hackers are already familiar with it．The least hackable password，then，would be a long string of completely random letters，numbers，spaces and symbols but you'd never remember it．
However，because length matters very much，the surprising truth is that a longish string of random English words，all in lower case﹣say， "awoken wheels angling ostrich"﹣is actually much more secure than a shorter password that follows your bank's annoying rules，such as "M nch3st3 r"．
（1）According to the writer，what's the reason for most people to write down their password？
（2）What else do people have to remember if they get locked out of their bank account？
（3）According to the Yahoo security breach， "ninja" is among those terrible passwords，isn't it？
（4）How long does it usually take a hacker to crack a password，such as "fpqzy"？
（5）Which password is probably a secure one， " m@nch3st3 r"or " welcome123"？
（6）What does a safer secure password possibly consist of？
五、句型转换
18．（2分）The little girl can count from 1 to 10. （改为否定句）
The little girl from 1 to 10.
19．（2分）Steve went to the meeting room in a hurry in order not to be late. （同义句转换）
Steve the meeting room in order not to be late.
20．（2分）Some people call the brain a living computer. （划线提问）
any people call the brain？
21．（2分）It took Devi less time to do a calculation than a computer. （保持句子意思不变）
Devi less time a calculation than a computer.
22．（2分）Make the model plane，Ken. （ 否定句 ）
Ken， the model plane.
23．（2分）To walk on the wet road is quite awful for us.（保持原句意思不变）
is quite awful for us on the wet road.
六、书面表达

四、任务型阅读
17．【解答】（1）Because it's hard for them to remember so many numbers.细节理解题。根据 you should be choosing a different，complex sequence of letters，numbers and symbols，and then memorizing it． （That's the first rule of the common knowledge on passwords：never，ever write them down．） But you don't do this，because it's hard for you to remember so many numbers．可知你应该选择一个不同的，复杂的字母，数字和符号序列，然后记住它。（这是密码常识的第一条规则：永远不要，永远不要写下来。）但你不会这样做，因为这对你来说很难记住这么多数字。故答案为Because it's hard for them to remember so many numbers.
（2）The answers to various security questions．细节理解题。根据 if you're probably getting locked out of your bank account，you began trying to remember the answers to various security questions．可知如果你可能被银行账户锁在门外，你开始试着记住各种安全问题的答案。故答案为The answers to various security questions．

（5）Neither of them．推理判断题。根据 the surprising truth is that a longish string of random English words，all in lower case﹣say， "awoken wheels angling ostrich"﹣is actually much more secure than a shorter password that follows your bank's annoying rules，such as "M nch3st3 r"．可知令人惊讶的事实是，一长串随机的英文单词，都是小写的，比如"awoken wheels angling ostrich"，实际上比遵循银行令人讨厌的规则（如"M nch3st3 r"）的较短密码安全得多。因此"米@nch3st3 r或者"欢迎123"都不是安全的密码。故答案为Neither of them．
（6）It consists of completely random letters，numbers，spaces and symbols．细节理解题。根据 The least hackable password，then，would be a long string of completely random letters，numbers，spaces and symbols but you'd never remember it．可知那么，最不容易破解的密码就是一长串完全随机的字母、数字、空格和符号，但你永远记不住。故答案为It consists of completely random letters，numbers，spaces and symbols．
五、句型转换

故答案为：hurried to。
20．【解答】What，do.考查特殊疑问句。根据题干中的划线部分可知就宾语a living computer进行提问，所以疑问词用what，其次在主语some people前加助动词do构成一般疑问句即可。
故答案为：What，do.
21．【解答】It takes sb.some time to do sth.＝Sb.spend some time doing sth.某人花多长时间做某事；根据原句时态用一般过去时，spend的过去式是spent.
故答案是 spent，doing
22．【解答】原句是祈使句，否定句在动词原形前加don't.
故答案是 don't make
