This went on for some time, day after day while the mother tried to understand what was happening.

Finally, little Tommy brought home his report card. He quietly put it on the table and went up to his room and hit the books. His mom looked at it and to her surprise, little Tommy got an A in math.

Mind Those Manners on the Subway

So, there you are, just sitting there in the subway car, enjoying that book you just bought. Suddenly, you feel someone leaning over your shoulder reading along with you. Or, the person sitting next to you takes out a nail clipper and begins cutting his or her nails.

Annoying? Many of us have to spend some time every day on public transportation. We all know that some behaviors are s____________ unacceptable.  So, to make the trip more pleasant, we suggest the following: 

 Let passengers get off the bus or subway car before you can get on. Getting off and on in an orderly m__________can save time for all. Stand away from the doors when they are closing.

Don't cut your nails or pick your nose on public transportation. 

Don't read over other people's shoulder. Many people do this on subways, but it's r__________ annoying. It can make people uncomfortable. They might think you're too stingy even to buy a newspaper. Or they might think you're judging their behavior.

 

D. Answer the questions(依据短文内容回答问题)

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. 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.

A recent security breach 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  nch3st3r".

79. According to the writer, what's the reason for most people to write down their password?

 

80. What else do people have to remember if they get locked out of their bank account?

 

81. According to the Yahoo security breach, "ninja" is among those terrible passwords, isn't it?

 

82. How long does it usually take a hacker to crack a password, such as “fpqzy”?

 

83. Which password is probably a secure one, “ m@nch3st3r”or “ welcome123”?

 

What does a safer secure password possibly consist of?

 

I.  26. B   27. B   28. A   29. A   30. C   31. D   32. C   33. C   34. D   35. B

   36. B    37. C   38. B   39. C

II.  40. C   41. F   42, A   43. E   44. B   45. D

III. 46. development   47.invented   48. fourth    49. calculating ; calculation

   50. less          51. nearly     52. living    53. electrical / electronic

IV. 54. How soon      55. study, · or      56. any longer    57. please don't

   58. enough, to      59. about solving

A. 60. C   61. D   62. B   63. C   64. C   65. B.

B. 66. C   67. C   68. C   69. B   70. B   71. D

C. 72. simply   73. manner   74. stand    75. others

   76. own     77. spread   78. really

D. 79. Because it's hard for them to remember so many numbers,

  80. The answers to various security questions. 81. Yes, it is.

  82. It usually takes them three and three quarters hours to crack.

  83. Neither of them. 84. It consists of completely random letters, numbers,spaces and symbols.
