If you and your friends wish to share a secret, you can write it in code, and no one else will be able to read it. Codes are one way of writing in secret. Ciphers (密码) are another. In a code each word is written as a secret code word or code number. In a cipher each letter is changed.

Codes and ciphers have played an important role in the history of the world. Julius Caesar, the Roman ruler who defeated almost all the countries in Europe about 2, 000 years ago, used a cipher when he sent secret messages to his troops. During the American Revolution, George Washington's spies used a kind of code to send him information about the enemy before his military action. In World War Ⅱ, the Americans "broke", or figured out, Japan's most important naval codes and got enough information to destroy a powerful Japanese fleet(舰队).

Storekeepers use codes to mark their goods. The codes show how much was paid for the goods or when they were added to the stock. Businessmen use codes to hide plans from their business enemies. Sometimes personal letters or diaries are written in code. Many people enjoy figuring out codes and ciphers simply as a hobby.

In the 16th century, codes and ciphers were very popular among scientists. They wrote messages to each other in code so that no one else would learn their secrets. Geronimo Gardano, an Italian astrologer(占星家), mathematician, and doctor, invented the trellis cipher. He took two sheets of paper and cut exactly the same holes in each one. Then he sent one sheet, which he called a trellis, to a friend and kept the other for himself. Whenever he wanted to write a message, he put his trellis over a clean sheet of paper and wrote the secret message through the holes. Then he removed the trellis and filled the rest of the paper with words that would make sense. When his friend received it, he put his trellis over the writing and read the secret message.

What does the underlined word "trellis"mean?

A. A piece of paper with many small holes.          B. A machine with a lot of small holes.

C. A letter with unreadable words and sentences.   

D. A sheet of paper with groups of Arabic figures.

Which of the following statements is true?

A. Ciphers can be broken or figured out more easily than codes.

B. You could read some words in Geronimo' s letter without his trellis.

C. The first person who ever used a cipher in history was Julius Caesar.

D. Fondness of using codes was the hobby of the scientists in the 16th century.

The best title of this passage is________.

A. Codes and Ciphers                  B. Differences between Codes and Ciphers

C. History of Codes and Ciphers         D. Inventors of Codes and Ciphers

People like to look in the mirror often when they have a young and beautiful face. However, when one grows old, nobody wants to see their wrinkled old face in the mirror any more. So, many old people seldom look at their faces in the mirror. This is completely wrong.
According to Wu Zhenyun, a professor from the Psychological Research Institute under the Chinese Academy of Sciences, a person’s willingness to look in the mirror can reflect his or her mentality. When people don’t care too much about their age, they will try to carry themselves with ease and natural poise (姿态). They don’t mind looking in the mirror to see their own faces. Some people even love to look in the mirror from time to time to see whether they keep a good appearance. In this way, mirror becomes their best friend that help them to look confident.
On the other hand, some people are afraid of being old. They don’t want to see the wrinkles on their face and their hair turning grey. So they don’t want to look in the mirror. This actually reflects a negative attitude they hold towards life. In the long term, they might suffer from psychological pressure or some sort of depression, which is actually not a wise act.
“ Everyone can make themselves look charming at every age stage. If one is confident, one will always look beautiful, it shows that they accept themselves.” professor Wu said.
Mirror cannot only give confidence to one. By looking in the mirror, one can even find the traces of some diseases from one’s own face.
67.Why does the mirror become the best friend for some people?
A. Because it brings much confidence to them.
B. Because it makes them more beautiful.
C. Because it tells whether they are clean or not.
D. Because it helps them find their own faults.
68.The fact that some people are afraid of looking in the mirror reflects that______.
A. they suffer from metal disease  B. they treat life in a negative way      
C. they are too ugly              D. they can’t bear the pressure of being old
69. The text tells us that______.
A. if you are willing to look in the mirror you are getting old
B. everyone can become attractive at any age
C. confidence can make a person look beautiful
D. old people will accept the reality when they are old
70. The writer wrote this passage to______.
A. advise people to look in the mirror constantly
B. reflect different attitude towards looking into a mirror
C. introduce a way of finding signs of disease from one’s face
D. analyze why people like and dislike to look in the mirror

The Internet has opened up a whole new online world for us to meet, chat and go where we’ve never been before.

But just as in face-to-face communication, there are some rules of behavior that should be followed when on line.  1. . Imagine how you’d feel if you were in the other person’s shoes.

For anything you’re about to send: ask yourself, “Would I say this to the person’s face?” If the answer is no, rewrite and reread.    2.    

If someone in the chat room is rude to you, your instinct (本能) is to fire back in the same manner. But try not to do so.   3.  If it was caused by a disagreement with another member, try to fix the situation by politely discussing it. Remember to respect the beliefs and opinions of others in the chat room.

   4.   Offer advice when asked by newcomers, as they may not be sure what to do or how to communicate. When someone makes a mistake, whether it’s a stupid question or an unnecessarily long answer, be kind about it. If it’s a small mistake, you may not need to say anything. Even if you feel strongly about it, think twice before saying anything. Having good manners yourself doesn’t give you license to correct everyone else.  5.  At the same time, if you find you are wrong, be sure to correct yourself and apologize to those that you have offended(冒犯).

It is not polite to ask others personal questions such as their age, sex and marital status. Unless you know the person very well, and you are both comfortable with sharing personal information, don’t ask such questions.

A. If you do decide to tell someone about a mistake, point it out politely.

B. It’s natural that there are some people who speak rudely or make mistakes online.

C. Repeat the process till you feel sure that you’d feel comfortable saying the words to the person’s face.

D. Everyone was new to the network once.

E. The basic rule is simple: treat others in the same way you would want to be treated.

F. When you send short messages to a person online, you must say something beautiful to hear.

G. You should either ignore the person, or use your chat software to block their messages.
