1 . Secret codes (密码) keep messages private. Banks, companies, and government agencies use secret codes in doing business, especially when information is sent by computer.

People have used secret codes for thousands of years.     1    Code breaking never lags (落后) far behind code making. The science of creating and reading coded messages is called cryptography.

There are three main types of cryptography.     2    For example, the first letters of “My elephant eats too many eels” spell out the hidden message “Meet me.”

    3    You might represent each letter with a number, for example. Let’s number the letters of the alphabet, in order, from 1 to 26. If we substitute a number for each letter, the message “Meet me” would read “13 5 5 20 13 5.”

A code uses symbols to replace words, phrases, or sentences. To read the message of a real code, you must have a code book.     4    For example, “bridge” might stand for “meet” and “out” might stand for “me.” The message “Bridge out” would actually mean “Meet me.”     5    However, it is also hard to keep a code book secret for long. So codes must be changed frequently.

A．It is very hard to break a code without the code book.

B．In any language, some letters are used more than others.

C．Only people who know the keyword can read the message.

D．As long as there have been codes, people have tried to break them.

E．You can hide a message by having the first letters of each word spell it out.

F．With a code book, you might write down words that would stand for other words.

G．Another way to hide a message is to use symbols to stand for specific letters of the alphabet.

2 . 根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

    1     However, it is possible to prevent stress as well as reduce its effect when it can’t be avoided. The following are ways to deal with stress.

    2     Running, walking, playing tennis, and working in your garden are just some of the activities you might try.

You should make every effort to get enough rest and eat well. If you easily get angry and can’t sleep well enough, or if you’re not eating properly, it will be more likely that you will fall into stressful situations.    3    

Schedule time for both work and entertainment. Don’t forget, play can be just as important to your health as work.    4     Go window-shopping or work on a hobby. Allow yourself at least half an hour each day to do something you enjoy.

Stress can result from disorganization and a feeling that “there’s so much to do, and not enough time”. Make a list of everything you have to do.    5    Remember: do one thing at a time, and check off each task it is completed.

A．If stress repeatedly keeps you from sleeping, you should see a doctor.

B．You’d better get into good living habits.

C．You need a break from your daily routine to just relax and have fun.

D．It is impossible to live completely free of stress.

E．Set out to do the most important task first.

F．Trying releasing the pressure through exercise is probably a good choice.

G．Stress can influence peopled thoughts and feelings.

3 . If something that you’re doing doesn’t challenge you, then it doesn’t change you. We all need some normal stress in our lives, after all.     1     So challenge the following limits:

1. Figure out what you are scared of and do it continuously.

If you are a salesman, and you’re scared of talking to people personally or over the phone, now, instead of being scared and thinking you will fail, spend at least five minutes a day to pick up the phone and make a call.     2     But don’t stop on the first try! Eventually, you can look at fear in the eyes and say, “Go on, I’m not scared!”

2. Take a class for a hobby you’ve been wanting to develop.

Make sure this hobby is not linked to your career; you have to relax and relieve your stress while performing this.     3     Apart from helping you challenge yourself, taking a class for your hobby may also give you extra income.

3. Set aside at least nine minutes a day for physical exercise.
    4     A simple 9-minute run around your neighborhood can do wonders for yourself. Exercise can not only help you maintain your regular weight, but also make you feel better about yourself.
4.     5    

Don’t just limit yourself to your fellow travelers — try to connect with the service staff. You never know what kind of people they’re going to be. Get out of your house or go online right now to book your class. Start to travel now and learn to challenge yourself.

A．You should do it continuously.

B．Someone may make you disturbed.

C．You don’t need to go to the gym.

D．Running in the gym may be a better choice.

E．You can never see any improvement if you stick to your comfort zone.

F．Travel and allow yourself to be interested in new people.

G．Some examples might be cooking, sewing, painting and so on.

4 . Are you facing a situation that looks impossible to fix?

In 1969,the pollution was terrible along the Cuyahoga River Cleveland, Ohio. It    1    (be) unimaginable that it could ever be cleaned up. The river was so polluted that it    2    (actual) caught fire and burned. Now, years later, this river is one of    3    most outstanding（杰出的）examples of environmental cleanup.

But the river wasn’t changed in a few days    4    even a few months. It took years of work     5    (reduce) the industrial pollution and clean the water. Finally, that hard work paid off and now the water in the river is    6    (clean) than ever.

Maybe you are facing an impossible situation. Maybe you have a habit    7    is driving your family crazy. Possibly you drink too much or don’t know how to control your credit card use. When you face such an impossible situation, don’t you want a quick fix and something to change immediately?

While there are    8    (amaze) stories of instant transformation, for most of us the    9    (change) are gradual and require a lot of effort and work, like cleaning up a polluted river. Just be     10    (patience).

5 . Arriving in Sydney on his own from India, my husband, Rashid, stayed in a hotel for a short time while looking for a house for me and our children.

During the first week of his stay, he went out one day to do some shopping. He came back in the late afternoon to discover that his suitcase was gone. He was extremely worried as the suitcase had all his important papers, including his passport.

He reported the case to the police and then sat there, lost and lonely in a strange city, thinking of the terrible troubles of getting all the paperwork organized again from a distant country while trying to settle down in a new one.

Late in the evening, the phone rang. It was a stranger. He was trying to pronounce my husband’s name and was asking him a lot of questions. Then he said they had found a pile of papers in their trash can(垃圾桶) that had been left out on the footpath.

My husband rushed to their home to find a kind family holding all his papers and documents. Their young daughter had gone to the trash can and found a pile of unfamiliar papers. Her parents had carefully sorted them out, although they had found mainly foreign addresses on most of the documents. At last they had seen a half-written letter in the pile in which my husband had given his new telephone number to a friend.

That family not only restored the important documents to us that day but also restored our faith and trust in people. We still remember their kindness and often send a warm wish their way.

6 . You may not have heard of Ashoka,   but for the past 27 years,this association, founded by Bill Drayton, has fought   poverty (贫穷)and sickness, promoted education and   encouraged small businesses. To support these worthy causes, Ashoka provides money for the world's most   promising "changemakers" seeking to solve (解决) urgent problems and would like to create a   world in which every citizen is a changemaker.

Drayton believes that anyone can become an agent for change. The important thing is to simply give yourself permission. If you see a problem that you care about, you can help solve it. The young in particular are willing to accept this concept because at heart every child wants to grow into a happy, healthy,   contributing adult. In fact ,It is many young people's ambition to set up programmes or businesses that improve social conditions. An excellent example is an Ashoka project started in 1995 in Dhaka, which handled the rubbish problem facing the city ,helped local farmers and provided an income for poor people there .

When Masqsood and Iftekhar began to study the problem of all the uncollected rubbish that lay in Dhaka’s streets. Attracting tats and disease , they discovered that 80% of it was natural waste . So they educated the poor people in the city to compost (把……制成堆粪)this waste . They knew that they would have a market for the end product because local farmers were struggling with chemical ferntilisers (化肥) which were expensive and had reduced the natural minerals in the soil over the years . At first , they were refused ,but once they were able to persuade that there was money to be made , the project took off. In 2009 sales were $14,000.

Drayton is optimistic that in ten years Ashoka will be making really serious, practical progress in bringing about social change by changing the way we look at economic development.
