12．Good health is the most valuable thing a person can have，but one cannot take good health for granted．It is important to remember that the body needs proper care in order to be healthy．There are three things that a person can do to help stay in good shape：eat right food，get enough sleep，and exercise regularly．
Proper nutrition （營(yíng)養(yǎng)） is important for good health．Your body cannot work well unless it receives the proper kind of"fuel"（燃料）．Don't eat too much food with lots of sugar and fat．Eat plenty of foods high in protein （蛋白質(zhì)），like meat，fish，eggs and nuts．Vegetables and fruits are very important because they provide necessary vitamins （維他命） and minerals．However，don't overeat．It is not helpful to be overweight．
Getting the proper amount of sleep is also important．If you don't get enough sleep，you feel tired and easily get angry．You have no energy．Over a long period of time a little a amount of sleep may even result in a change of personality （人的個(gè)性）．Be sure to allow yourself from seven to nine hours of sleep each night．If you do，your body will feel strong and refreshed，and your mind will be sharp．
Finally，get plenty of exercise．Exercise firms the body，strengthens the muscles，and prevents you from gaining weight．It also improves your heart and lungs．If you follow a regular exercise program，you will probably increase your life-span （壽命）．Any kind of exercise is good．Most sports are excellent for keeping the body in good shapes：basketball，swimming，bicycling，running and so on are good examples．Sports are not only good for your body，but they are enjoyable and interesting，too．
If everybody，were to eat the right foods，get plenty of sleep and exercise regularly，the world would be a happier and healthier place．We would all live to be much older and wiser．

Dear Jim，
Dear Jim，
How is it going？Thank you for your support on my upcoming attendance in the CCTV program The Reader．
The book I have chosen is"Fu Lei's Family Letters"in which he shared his view about art and life in order to guide his son．There are two reasons why I've decided to read one of his letters to the audience nationwide．Firstly，you can feel the profound fatherly love and his efforts to guide the next generation，which I believe will touch the youngsters like me．Besides，many traditional virtues，such as integrity，can be found in his works，which can inspire students like us．
The book has an immense influence on me．Actually，it is this book that changed me from a troubled teen to a caring son．Besides，the wisdom in the book helps me shape a positive attitude towards life and future．Thus，it came to my mind the moment I got the invitation．
That's all about it．I hope my introduction can be of some help．Is there any book that also plays an important role in your life？I'm looking forward to your reply!
Yours，
Li Hua

7．Delicious Culture
Cultural identity is what helps a nation，an area or a social group to distinguish itself from others．Across the globe and throughout human history，the land and climate have made groups of people develop their own food preferences，（25）whichhave become their traditional cuisines （美食） and their diversified lifestyles．However，this kind of food identity is fading slowly due to changes in the way we live today．
（26）What food is available is no longer decided by geography．As the world shrinks，our area's preferences will surely become more similar to （27）those of the rest of the world．As international food industry consultant Chris Lukehurst told The Guardian，you'll see Italian teens ignoring their local wine in favor of American-style beer．And while coffee and potato chips were"almost unknown"in China a decade ago，they are now becoming popular here．
However，（28）to win （win）as many customers as possible，multinational companies change their products a little for each market．Take fast food （29）for example．In China，both McDonald's and KFC include much more salad in their meals to help provide the three food groups necessary in every meal：grains，protein and vegetables．They also offer rice porridge，soy milk drinks and youtiao，or fried dough sticks，in breakfast menus to suit local customers．
（30）Although only a certain culinary （烹飪的） sign of culture is fading，UNESCO has decided to safeguard the world's food-related cultural heritage （遺產(chǎn)）．In 2008，cuisines from specific cultures （31）were included （include） in its List of Intangible Cultural Heritage （非物質(zhì)文化遺產(chǎn)）．
Now，let's take a food journey across the world to understand （32）why we often say that you are what you eat，or you are what your ancestors ate．

17．People select news in expectation of a reward．This reward may be either of two kinds．One is related to what Freud calls the Pleasure Principle，the other to what he calls the Reality Principle．For want of better names，we shall call these two classes immediate reward and delayed reward．
In general，the kind of news which may be expected to give immediate reward are news of crime and corruption，accidents and disasters，sports，social events，and human interest．Delayed reward may be expected from news of public affairs，economic matters，social problems，science，education，and health．
News of the first kind pays its rewards at once．A reader can enjoy an indirect experience without any of the dangers or stresses involved．He can tremble wildly at an axe-murder，shake his head sympathetically and safely at a hurricane，identify himself with the winning team，laugh understandingly at a warm little story of children or dogs．
News of the second kind，however，pays its rewards later．It sometimes requires the reader to tolerate unpleasantness or annoyance-as，for example，when he reads of the threatening foreign situation，the mounting national debt，rising taxes，falling market，scarce housing，and cancer．It has a kind of"threat value．"It is read so that the reader may be informed and prepared．When a reader selects delayed reward news，he pulls himself into the world of surrounding reality to which he can adapt himself only by hard work．When he selects news of the other kind，he usually withdraws from the world of threatening reality toward the dream world．
For any individual，of course，the boundaries of these two classes are not stable．For example，a sociologist may read news of crime as a social problem，rather than for its immediate reward．A coach may read a sports story for its threat value：he may have to play that team next week．A politician may read an account of his latest successful public meeting，not for its delayed reward，but very much as his wife reads an account of a party．In any given story of corruption or disaster，a thoughtful reader may receive not only the immediate reward of indirect experience，but also the delayed reward of information and preparedness．Therefore，while the division of categories holds in general，an individual's tendency may transfer any story from one kind of reading to another，or divide the experience between the two kinds of reward．
What news stories do you read？
Division of news stories●People expect to get （66）rewards/rewarded from reading news．
●News stories are roughly divided into two classes．
●Some news will excite their readers instantly while others won't．
（67）Explanations of the two classes●News of immediate reward will seeming take their readers to the very frightening scene without actual（68）involvement．
●Readers will associate themselves closely with what happens in the news stories and （69）share similar feelings with those involved．
●News of delayed reward will make readers suffer，or present a （70）threat to them．
●News of delayed reward will induce the reader to （71）prepare for the reality while news of immediate reward will lead the reader to （72）withdraw from the reality．
Unstable boundaries of the two classes●What readers expect from news stories are largely shaped by their（73）profession（s）/intention．
●Serious readers will both get excited over what happens in some news stories and （74）adapt themselves to the reality．
●Thus，the division，on the whole，（75）dependson the reader．

2．Most people think that the capital of the movie world is Hollywood in the United States．However，the real movie capital is Mumbai，in India．Mumbai used to be known as Bombay，and so the film industry there is called"Bollywood．"Bollywood makes twice as many movies each year as Hollywood-more than 800 films a year．
The movies from Bollywood are very different from Hollywood movies．For one thing，Bollywood movies are much longer than most Hollywood movies．Most Bollywood movies are more than three hours long，and contain singing，dancing，action，adventure，mystery and romance（but usually no kissing）．Because Bollywood films contain so many different features，this style of film is sometimes called a"masala"film．（"Masala"is an Indian word for a mixture of species．）
Another big difference between Bollywood and Hollywood movies is the way movies are made．It takes much longer to make a movie in Hollywood than in Bollywood．In fact，filming may began on a Bollywood movie before the script is finished．The director and writer can make up the story while the film is being made．Sometimes they will even write the script by hand instead of taking time to type it．
Bollywood actors are very popular and some are in such high demand that they may work on several movies at the same time．They may even shoot（拍攝） scenes for several films on the same day using the same costumes and scenery．Since most Bollywood movies follow the same kind of story，shooting scenes for several films at the same time is not a big problem for actors or directors．This also helps keep the cost of Bollywood movies lower than the cost of Hollywood movies．The average Bollywood film，with a budget（預(yù)算）of only two million US dollars，seems very cheap compared to the average budget of sixty million US dollars for a Hollywood film，thirty times as much!

56．What is the main topic of the reading？C
A．Famous stars in Bollywood．
B．How Hollywood movies are made．
C．The difference between two movie industries．
D．The history of movie-making in India．
57．What is NOT true about Mumbai？B
A．It is the movie capital of India．
B．The new name is Bombay．
C．More movies are made there than in Hollywood．
D．It is less expensive to make films there than in Hollywood．
58．Why are Bollywood films often called"masala"films？D
A．They are very popular．
B．They show Indian culture．
C．They are much longer than Hollywood films．
D．They mix different styles of movies．
59．Bollywood films are cheap to make becauseD．
A．they are shorter than Hollywood films       
B．the scripts are written by hand
C．the movies do not use any special effects       
D．one movie can reuse things from other movies
60．Which of the statements would the writer probably agree with？A
A．Most Bollywood movies are very similar．
B．It takes a lot of money to make a good movie．
C．Only Indian people can understand Bollywood movies．
D．Hollywood movies are too short．
