A
Today many people call Paul Cezanne the Father of Modern Painting.In fact，he sold few pictures and won no prizes.He had to be supported by his father and was also helped by the writer Emile Zola，his boyhood friend.Only in the last ten years of his life was his greatness recognized.
Paul Cezanne was born in Aix­en­Provence，France，on Jan.19,1839.His father，Louis­Auguste，was a successful banker.Cezanne received an education at the College Bourbon and studied drawing at the Aix Museum.After studying for a short time at law school and working in his father’s bank，he went to Paris to study painting.Then he often returned to Aix.He worked many summers painting the scenery (景色) near his father’s home away from the center of the city.
During the Franco­Prussian War in 1870，Cezanne fled to L’Estaque，near Marseilles.With him went Hortense Fiquet.In 1872 their son Paul was born.
Cezanne took part in the first exhibition of impressionist (印象派的) paintings in 1874，though he later broke with the impressionists.He was more concerned with structure and color than with the effects produced by light.
Not until Cezanne was about 60 years old did galleries and museums begin to look for his works.Even with his newfound success he still remained unsociable.However，he continued to paint until a week before his death on Oct.22,1906.
Most 20th­century painters were influenced by Cezanne.He invented a way of modeling three­dimensional (三维的) forms by painting in small areas of color.He painted from nature but often changed a shape or its color to express its special effect.His finest works are very calm and peaceful but they are powerful expressions of forms in space.

答案：　A
2．What was Paul Cezanne’s attitude towards impressionist paintings in his later life?

The Internet plays a big part in human life.We use it for work and pleasure.We use it to learn a new language.We find advice on it.We use it to connect with family and friends.We use it to stay in touch with events we care about.The list goes on and on.
Well，that train has left the station.But can using the Internet too much be bad for our health？It might be，researchers say.A new study finds that heavy Internet use may be connected to high blood pressure (血压) in an unlikely group : teenagers.
High blood pressure makes your heart and blood vessels (血管)work too hard.Over time，this extra pressure increases your risk of a heart attack.High blood pressure can also cause heart and kidney (肾脏)disease.It is also closely linked to a brain disease.
The Henry Ford Hospital in Detroit，Michigan did the study.335 young people，from 14 to 17 years old ，took part in it.134 of the teens were described as “heavy Internet users.”And researchers found that out of these 134 teens,26 had high blood pressure.The researchers say the study is the first to connect heavy web use with high blood pressure.Other research has connected heavy Internet use with anxiety，depression and obesity(肥胖)．
The lead researcher is Andrea Cassidy­Bushrow.She said，“Using the Internet is part of our daily life，but it shouldn’t ruin us.” Ms Cassidy­Bushrow adds that it is important for teens to take regular breaks from their computers or smartphones and do some kind of physical activity.She also suggests that parents limit (限制) their children’s use of the Internet to two hours a day，five days a week.

沁园春·雪 <毛泽东>
北国风光，千里冰封，万里雪飘。
望长城内外，惟余莽莽；
大河上下，顿失滔滔。
山舞银蛇，原驰蜡象，
欲与天公试比高。
须晴日，看红装素裹，分外妖娆。
江山如此多娇，引无数英雄竞折腰。
惜秦皇汉武，略输文采；
唐宗宋祖，稍逊风骚。
一代天骄，成吉思汗，
只识弯弓射大雕。
俱往矣，数风流人物，还看今朝。
薄雾浓云愁永昼， 瑞脑消金兽。 佳节又重阳， 玉枕纱厨， 半夜凉初透。
东篱把酒黄昏后， 有暗香盈袖。 莫道不消魂， 帘卷西风， 人比黄花瘦。
