Anyone who ever wondered why a dying plant, say, a freshly-cut red rose may appeal to a lady friend, might take some comfort in science, which once again offers us a reasonable answer to one of the world’ s great mysteries.

Beyond a common preference in people for blue, “the long history of color preference studies has been described as ‘confusing and contradictory(矛盾的)’,” write scientists Anya Hurlbert and Yazhu Ling of England’ s Newcastle University, authors of a new study in the journal Current Biology. “This fact is perhaps surprising,” they said, “though the popularity of the concept that little girls differ from boys in preferring pink.”

But the scientists believe they have an answer to this scientific mystery, discovering women’s preference for red, hidden above the average liking for blue.

In their study, the pair quickly flashed color cards, displaying many different aspects, at 208 volunteers, mostly Britishers but with a number of Han Chinese, who moved to the United Kingdom recently. Tested in three different experiments, the researchers found out a small but significant preference for reddish colors in the female volunteers.

Puzzled, the authors realized that most of the difference between men and women came in the form of a preference for green VS red in the color cards, regardless of the other slight differences such as the slightly blue ones that everyone liked. Why might this be?

Evolution might offer an answer, they reason. Human color perception(感知), the assessment of three separate color types — red — green — blue— in our vision (视觉) is a relatively recent addition to our line of mammals(脯乳动物)

Adding weight to their argument, they found the women who are most typically feminine(女性的) on a psychological survey also had the biggest preference for reddish colors. “My love is like a red, red rose,” wrote the Scottish poet Rober Burns in 1794.

根据短文内容，从下框A~F选项中选出能概括每段主题的最佳选项。选项中有一项为多余项。

1.There is considerable variety in university classrooms in the United States. Because of diverse teaching methods and non-standardized curricula (课程), no two courses are the same. Undergraduate courses are considerable different from graduate courses. The classroom atmosphere in expensive, private universities may differ from that in community colleges， which are free and open to everyone.

2.Participation in the classroom is not only accepted but also expected of the student in many courses. Some professors base part of the final grade on the student's oral participation. Although there are formal lectures during which the student has a passive role (i.e., listening and taking notes), many courses are organized around classroom discussions, student questions, and informal lectures.

3.Many teachers believe that the responsibility for learning lies with the student. (Courses are not designed merely for students to pass exams.) The ideal student is considered to be one who is motivated to learn for the sake of learning, not the one interested only in getting high grades.

4.Ideally, the teacher-student relationship at universities is characterized by trust. Thus, cheating on tests, Plagiarizing (抄袭) in written work, presenting other's ideas as original, and turning in homework completed by someone else are all prohibited (禁止).

5.Relationships between students in the classroom can be cooperative or competitive. International students should not hesitate to ask for help if it is needed. in classes where such a grading curve is used, students may be reluctant to share lecture notes or information for fear that their own grades will suffer.

Friendship can deeply affect the physical and mental health of both men and women. Studies show that people who have no friends or who are lonely, are more likely to die earlier, get sick more often and suffer greater physical wear and tear(折磨）than those who have a support system of friends.
Sometimes, family members may be more likely to give you advice or tell you what you don't want to hear. It may not be as good as a friend who will listen to you and guide you, but support your decisions anyway. The most important elements about friendship are those who suffer support and do not judge your decisions based on society.
One reason for the link between social support and good health practice seems to be that people who feel cared for by others are less stress-out and protected against the symptoms(症状）of depression and loneliness.
Generally, women benefit most because of how they deal with stress. Women are more social in how they deal with stress than men while men are more likely to have a "fight or flight” reaction. Women also tend to have larger, denser social network, in which more people know each other and help each other, while men typically have smaller groups of friends and will rely on their wives or other important people for more support. While all these affect people psychologically (心理上）_, friendship brings comfort that reduces the ill effects of stress, and the sex difference also contributes to the differ­ence in the length of one's life time.
