12．In today's fiercely competitive business environment，companies need to communicate information concerning a whole range of issues in a clear and precise manner to their customers．This is particularly so in the case of companies which do business in areas such as manufacturing，information technology （IT），engineering products and services-companies whose products and services may not be understood by a customer not familiar with its technical aspects．
These communication materials are prepared in a company these days by"technical writers"-people who can effectively communicate to an intended audience．
Technical writing and writing text-books are poles apart．The former is aimed at those who do not have an in-depth knowledge about a product and therefore should be direct and easy to understand．Too many technical terms would only add to the confusion of the customer．Technical writers first need to understand the technical information themselves，before trying to communicate it in easier language to the customers．Even graduates of English literature are often found wanting when it comes to creative and effective writing．
This simply means that those with a Bachelor's degree in English Literature along with a  diploma/degree in Journalism and having a Post Graduate Diploma in Computer Applications （PGDCA） are ideal （理想的） candidates for being employed as technical writers．
A career in technical writing is seen as a good choice for women mainly because it is widely held that women are more gifted in creative writing than men and the job does not involve too much travelling or working at night．
28．What are"technical writers"supposed to do？A
A．To write about the company's products or services in clear，easy language．
B．To write about the company's products using correct technical terms．
C．To effectively communicate to an intended audience by writing letters．
D．To travel around to persuade people to buy the company's products or services．
29．Which of the following best explains the underlined word"wanting"in Paragraph 3？D
A．being needed．        
B．wanting to write．
C．hoping to be employed．    
D．lacking in ability．
30．What would happen if many technical terms are used in technical writing？C
A．It would sound too formal．    
B．It would help engineers a lot．
C．It would confuse the customer．
D．It would produce a better effect．
31．Who would be the best candidate for a technical writer？B
A．A man with degrees in English literature and Journalism and a PGDCA．
B．A female with degrees in English literature and Journalism and a PGDCA．
C．A male graduate of English literature with a diploma in Journalism．
D．A woman with a degree in English literature along with a diploma in Journalism．

11．The US government has started a website，Admongo，to help children think critically about the advertising aimed at them．It claims to provide visitors with an"aducation"through games and other entertainment．
A cartoon man dressed in old time pilot clothing greets visitors to Admongo．"Call me Haiz"，he says upon arrival in a rocket ship that opens up with a crazy world inside it．Spacey dance music plays in the background as Haiz tells visitors that they need to learn about advertising．
Its inventors say eight to twelve years old is the age kids develop their critical thinking abilities．Kids that age are also a big market for advertisers．
The idea behind Admongo is to teach children three things：To identify the advertiser．To know what the advertiser is really saying．And to know what the advertisement is trying to get the child to do．
Children learn these things through a video game．They create their own game character．They can choose different skin colors，hair styles，eye and mouth shapes．Then they begin a trip through ad-land，where there are ads on buses and billboards．The players have to find all the marketing in the neighborhood before they can move on to the next level．
The Admongo game takes players inside a home，to the advertising studio and everywhere else ads can be found．It is a complete exploration of the world of marketing．
One such area is food marketing．The Federal Trade Commission（FTC） says it is a big business．The FTC estimates that food，drink and fast-food restaurants spent more than one and a half billion dollars on advertising to young people in 2009．
The FTC says children are important for three reasons．They buy products．They influence parents and caregivers to buy．And they are the future adult buyers of the products．
A recent study says most advertising aimed at children is for foods of the lowest nutritional value．First Lady Michelle Obama has said she would like to see advertisers marketing healthy foods for children．

41．What is the best title of the text？B
A．The guide of Admongo
B．An aducation website for children
C．A popular online video game
D．A website aimed at children
42．Why did the government start the website？C
A．To attract the biggest market of buyers．
B．To sell the products of its company．
C．To help children know about advertising．
D．To advertise the video game for children．
43．What can players do in the website game？A
A．Choose hair styles for their character．
B．Travel to a supermarket．
C．Eat in a fast-food restaurant．
D．Play video games during the trip．
44．Children are important for advertising because they areB．
A．important for the society
B．the most potential buyers
C．easily influenced by ads
D．easily affected by poor products
45．According to Michelle Obama，lots of food advertised for children areD．
A．healthy                        B．of high nutrition
C．yummy                          D．of low quality．

1．For a long time being happy was considered something that just happened，and there was nothing special to do about it．Now we know that getting along with ourselves and with other people is something that we can work at．It is possible to act in such a way that other people will like us better．One way is being unselfish，not wanting everything our own way or demanding the best share of everything，including the attention of our friends．Another way is to look for good points，not bad ones in other people．It is surprising how successful this treasure hunt can be．
You don't have to be spineless （懦弱） in order to be popular．In fact，you will be liked and respected if you are not afraid to stand up for your rights．But do it politely and pleasantly．Being friendly and polite to your own group，to older people，to strangers and especially to those who do not look important or do not interest you is one way to develop a good character．
You cannot expect to be perfect，and so you must learn not to be too unhappy when you make a mistake．Everyone makes mistakes，and no one is to be blamed unless he refuses to learn from them．Many young people become discouraged when they recognize in themselves qualities that they do not like-selfishness，laziness and other unpleasant qualities．Just remember that we all have some of these faults and have to fight against them．
At the same time，it is important to remember that，while you are probably no worse than others，chances are that you are not much better，either．The surest way to be happy is to think yourself above other people．When something is wrong，it is good sense to try to make it right．Perhaps you don't like a teacher or a classmate．Try to see why，and look at yourself，too，to be sure that you are not doing something to make that person dislike you．In time，things may turn out all right if you just keep trying to be pleasant and polite．If things do not turn out all right，then you will simply have to get along the best you can with the situation，without thinking too much about it．Worrying never helps in a situation you can't change．
50．One of the two ways the author suggested for us to get along well with others is
B
A．to draw the attention of our friends
B．to pay more attention to other people's strong points
C．to look for treasure in order to be successful
D．to demand the best share of everything
51．The passage shows that there is no perfect person but someone should be blamed if heD．
A．makes a big mistake
B．is selfish and lazy
C．is very unhappy about his unpleasant quality
D．does not draw a lesson from his own fault
52．The passage implies that in order to be a happy person，one should consider oneselfB
A．no better than others
B．a(chǎn)s having something better than others
C．not the same as others
D．a(chǎn)s having better chances than others
53．The purpose for the writer to write the passage is toB．
A．train you to be perfect
B．show you the way to be happy
C．teach you how to be popular among your friends
D．tell you how to act when you dislike a person．

6．A good friend of mine lives about one hour away．I called her last week and found out that she wasn't doing well at work，which would make the following year a little more difficult．After hanging up the phone，I decided to offer to help her，but I couldn't think of what to do．However，opportunities come themselves when you're not even looking for．
A few days later，some friends and I happened to be eating desserts at a restaurant in her city．As we were looking at the menu，I turned to my friends and asked them if they wanted to join in a game．After explaining the idea，they decided to take 15 minutes to make someone's day．We ordered an extra dessert，wrote a note，added a smile card and were off．However，there was one problem：I had no idea where she was．

We drove to her work place and one of my friends became the delivery（投遞）person．He went in to look for my friend，found her，didn't really answer her questions and walked out，saying he's simply a delivery person．
He ran out quickly and I bent down as we drove by to make sure she didn't follow him out．Afterwards，all of us had this huge smile on our faces．We felt as if we had just planned a surprise party or something．
