1．In my living room，there is a plaque （匾） that advises me to"Bloom （開花） where you are planted．"It reminds me of Dorothy．I got to know Dorothy in the early 1980s，when I was teaching Early Childhood Development through a program with Union College in Barbourville，Kentucky．The job responsibilities required occasional visits to the classroom of each teacher in the program．Dorothy stands out in my memory as one who"bloomed"in her remote area．
Dorothy taught in a school In Harlan County，Kentucky，Appalachian Mountain area．To get to her school from the town of Harlan，I followed a road winding around the mountain．In the eight-mile journey，I crossed the same railroad track five times，giving the possibility of getting caught by the same train five times．Rather than feeling excited by this drive through the mountains，I found it depressing．The poverty level was shocking and the small shabby houses gave me the greatest feeling of hopelessness．
From the moment of my arrival at the little school，all gloom （憂郁） disappeared．Upon arriving at Dorothy's classroom．I was greeted with smiling faces and treated like a queen．The children had been prepared to show me their latest projects．Dorothy told me with a big smile that they were serving poke greens salad and cornbread for"dinner"（lunch）．In case you don't know，poke greens are a weed-type plant that grows wild，especially on poor ground．
Dorothy never ran out of reports of exciting activities of her students．Her enthusiasm never cooled down．When it came time to sit for the testing and interviewing required to receive her Child Development Associate Certification，Dorothy was ready．She came to the assessment and passed in all areas．Afterward，she invited me to the one-and-only steak house in the area to celebrate her victory，as if she had received her Ph．D．degree．After the meal，she placed a little box containing an old pen in my hand．She said it was a family heirloom （傳家寶），but to me it is a treasured symbol of appreciation and pride that cannot be matched with things．（360 words）

A．a warm welcome                                                 
B．the sight of poke greens
C．Dorothy's latest projects                                       
D．a big dinner made for her

A．She was invited to a celebration at a restaurant．

C．However poor you are，you have the right to education．

9．Directions：Read the following text and choose the most suitable heading from A-F for each paragraph．There is one extra heading which you do not need．
A．Manufacturing industry in information economy
B．News in the age of information
C．Argument about individual accounts and their reliability
D．Be your own investigative journalist
E．Don't believe everything you read in the newspapers．
F．Information is presented in an entertaining way．
76．B
With the arrival of the age of"information economy"，intellectual work is becoming a more important source of wealth than manufacturing．Organizations in all walks of life are doing more to spread their information．So people of the Public Relations are hired to speak for them．A lot of our news is actually collected from press releases and reports of events intentionally staged for journalists．In the information age，journalists spend their time，not investigating，but passing on the words of a spokesperson．
77．E
There is a joke in the novel Scoop about the newspaper's owner，Lord Copper．The editors can never disagree with him．When he's right about something they answer"definitely"，and when he's wrong they say"to some extent，Lord Copper．"It seems reasonable to suppose that，in the real world，the opinions of such powerful people still influence the journalists and editors who work for them．
78．F
In countries where the news is not officially controlled，it may be provided by commercial organizations who depend on advertising．The news has to attract viewers and maintain its audience ratings．I suspect that some stories get air-time just because there happen to be exciting pictures to show．In Britain，we have the tabloid newspapers which millions of people read simply for entertainment．There is progressively less room for historical background，or statistics，which are harder to present as a sensational story．
79．C
There is an argument that with spreading access to the internet and cheap technology for recording sound and images we will all be able to find exactly the information we want．People around the world will be able to publish their own eye-witness accounts and compete with the widely-accepted news-gatherers on equal terms．But what it will mean also is that we'll be subjected to a still greater amount of nonsense and lies．Any web log may contain the latest information of the year，or equally，a made-up story that you will never be able to check．
80．D
Maybe the time has come to do something about it，and I don't just mean changing your choice of TV channel or newspaper．In a world where everyone wants you to listen to their version，you only have two choices：switch off altogether or start looking for sources you can trust．The investigative journalist of the future is everyone who wants to know the truth．
