[不定项选择题]This is the age of the quick action. We have instant satisfaction, fast food, speed reading, mobile phones; even the stress management books have titles like "Stress Management in 60 Seconds". Canadian Classics Professor Margaret Visser points out that the perception that we have "no time" is one of the most strict concepts of Western culture. Visser says that "no time" is used as an excuse and also as a spur (刺激); it both goads us and forces us, just as a concept such as "honour" did for the ancient Greeks. According to Visser, the feeling that Westerners have "no time" is abstract, quantitative, amoral (非道德性的), unarguable, bringing pressure on each person as an individual. At the same time, the "no time" excuse escapes censure by claiming to be a condition created entirely out of our good fortune. Life offers "so many pleasures, so many choices". The fact that women now work outside the home has contributed to the "no time" trend. But more important, Visser says, is the fact that feeling rushed has become an important component of our economy. Marketing of "time-saving" products causes people to buy more and work longer. So we eat out or buy prepared food to save time. The fax-it-to-me-in-my-car technology only contributes to the constant hurry. In our rushed and exhausted state, even the obligation (义务) to sit down to casual meal with family seems like a pressure. In comparison with the decision to act on a sudden whims (一时的兴致) to consume a microwave mug of soup, the act of eating together and not getting up from the table until everyone else has finished seems an incredibly time-consuming event. Being in one′ s own personal hurry in the West is somehow "free and preferable". We can learn from the passage that "no time" trend ___________.
A.exerts pressure on the individual
B.is very desirable to the individual
C.is not harmful if you have no control of events
D.has caused heart diseases and psychological problems

[不定项选择题]共用题干 Ha!The Sdence of When We Laugh and Why
It's certainly possible to over-analyze a joke._______(46)Considering the abundant research on the topic,maybe not.
Scott Weems,a neuroscientist,takes readers on a wide-ranging tour that explains what humor is and why readers should care.______(47)Humor improves interpersonal relationships,and studies show that simply watching a funny movie can lower stress,improve immune system response and even help viewers better solve problems.
The complexity of the human brain makes humor possible,Weems argues,and it also helps explain how some people can find a joke hilarious while others deem it grossly offensive.
Humor takes many forms-as many as 44 by one researcher's count-but shares certain traits and themes.From puns and riddles to slapstick（打闹剧）,humor is inherently subversive , Weems says , often treating serious subjects with frivolity（轻浮）or even rudeness.______(48) Ha ! Isn ' t a self-help guide to being funny , though a careful reader can find useful nuggets（块金） throughout?______( 49 ) Surprise helps , too , whether it ' s the incongruity（不协调）of an elephant hiding in a cherry tree or the absolute improbability of Raquel Welch and the pope ending up in the same lifeboat.
The final chapter divulges（透露）Weems's semi-successful attempt at stand-up comedy.He got a few laughs,he says,but not where he expected them. ______(50)The joke that got Weems the most laughs,and judged by one website's readers as the best in the world,is a story that he had practiced many dozens,maybe hundreds,of times. _______(46)
A.Prisoners of war and others in dire situations,for instance,often turn to dark humor.
B.It turns out that humor influences health and social well-being in many ways.
C.The funniest jokes carry a little edginess（急躁）,but not too much.
D.But can the same be said for humor as a whole?
E.Maybe practice does make perfect.
F.Laughter is the bridge between dreams and reason,and ev6ry good bridge needs abutments.
