Girls really prefer pink and boys prefer blue, recent research shows. The reasons could have its origins in the hunt for food on the African savannah  thousands of years ago. Evolution may have developed women's preference for pink, perhaps because it helped to find ripe fruit and healthy men with reddish faces, while both men and women have a natural desire for blue, according to scientists at prefix = st1 /NewcastleUniversity. " Everyone in today's western culture, from parents to toy manufactures, seems to assume that little girls like pink." Said Prof. Anya Hulbert, who wanted to find out whether the reason was cultural or to do with biology. A love of salmon,  _ and coral does seem to be rooted into females, rather than picked up from their mothers. The participants in the study were Chinese and British. The Chinese students showed a marked preference for red, " Culture may contribute to this natural female preference," said Pro. Hulbert. In her experience, 208 young adult men and women were asked to select, as rapidly as possible, their preferred color1. Hulbert and her colleague Dr. Yazhu Ling marked the results and found that while men preferred blue, women tended to choose pink. Hulbert said she could only prefer about the preference for blue: " Here again, I would favor evolutionary arguments. Going back to our savannah days, we would have a natural preference for a clear blue sky, because it signaled good weather. Clear blue also signals a good water source." The passage mentions " the African savannah" to show that  _  . A) the ancient Africa was a a beautiful place B) human beings lived in Africa at first C) women and men have different color1 preference D) color1 preference has its historical origins

Barack Obama urged congressional leaders on Monday to act quickly to pass a huge stimulus package for the U.S. economy. He met with a (concerning or involving two different political parties) group of lawmakers on Capitol Hill. Later he met individually with Democratic and Republican House and Senate leaders and spoke to a bipartisan leadership gathering. In comments to reporters early on Monday, he emphasized the urgency of finalizing economic  . "We have got an extraordinary economic challenge ahead of us," he said, "We are expecting a sobering job report at the end of the week. Nancy Pelosi and her staff have been extraordinarily helpful in working with our team so that we can shape an economic recovery and reinvestment plan that starts putting people back to work." Mr. Obama wants tax cuts for individual Americans and businesses to make up a significant portion of expected legislation. This could involve as much as $300 billion of a bill that is likely to go beyond $700 billion and include aid to cash-poor U.S. states, and money for alternative energy and a range of   projects. Later, Mr. Obama said he expects to be able to sign legislation as soon as the end of this month, adding that quick action is necessary to "break the drive of the U.S. economic depression". Emerging later from bipartisan talks with Mr. Obama, Nancy Pelosi said lawmakers discussed with the president how to pass a stimulus package as quickly as possible. "An economic recovery package that will create jobs immediately and will grow the economy and that is what we talked about today," said Nancy Pelosi. "How we could do this fast, deliberatively and to act upon it soon." Just how soon that would be, Pelosi would not say. How much support Democrats can obtain from Republicans will depend on the details. But the severity of the U.S. economic depression has created considerable bipartisan backing for quick action. Senate Majority Leader, Harry Reid said: "There are investments that we need to make on behalf of the American people to turn... What is the bipartisan leaders' attitude towards this meeting? A) Uncertain. B) Hopeful. C) Disappointed. D) Indifferent.

There was a time when, if a lady got onto a crowded bus or train, a gentleman would immediately stand up and offer her his seat. No more, though. Today, a gentleman will probably look out of the window, or, if he feels a bit guilty , hides behind his newspaper. Either way, the lady will have to stand until someone else gets off. You can't entirely blame men for this change in manners. The days are gone when women could be referred to as the weaker sex. A whole generation of women has grown up demanding equality with men; not just equality in jobs or education, but in social attitudes . Hold a door open for some women and you're likely to get an angry lecture on treating women as inferiors , unable to open doors for themselves. Take a girl out for a meal and she'll probably insist on paying her share of the bill; though on second thoughts perhaps that's not such a bad idea. It's no wonder, then, that men have given up some of the gestures of politeness and consideration which they used to show towards women. On the other hand, automatic male (men) politeness is perhaps slowly being replaced by true consideration for the needs of women, so that men can see women as equal human beings. Maybe that's worth standing in the bus or train. The passage mainly tells us   _  . A) gentlemen and ladies have equal rights on a bus or train B) ladies wonder why gentlemen offer their seats to them C) gentlemen consider politeness to be more important than ladies do D) the change in manners has taken place between men and women
