    According to a recent study out of the University of Pennsylvania's Wharton School, men with shaved heads are considered to be more manly, powerful, and successful than those with longer hair or thinning(稀少的) hair. Besides, in some cases, they are considered to have greater leadership potential (潜力). That may explain why the power-buzz look has become popular among business leaders in recent years.

    Albert Mannes, Wharton management lecturer, said he was encouraged to do the research after noticing that he was treated with more respect when he shaved off his thinning hair.

    Mannes did three experiments to test people's impression of men with shaved heads. In one of the experiments, he showed 344 subject photos of the same men in two versions: one showing the men with hair and the other showing them with their hair digitally removed, so their heads appear shaved. In all three tests, the subject report found the men with shaved heads are more dominant(占优势的) than their hairy counterparts(对应的人).

    The study found that men with thinning hair were viewed as the least attractive and powerful. For those men, the solution could be as cheap and simple as a shave.

    New York image consultant Julie Rath advised her clients to get closely cropped when they start thinning up top. “There is something really strong, powerful and confident about laying it all bare(光秃的),” she said, describing the thinning look as kind of raunchy(不修边幅的).

    Not everyone needs a bare head. Rick Devine, 55, the CEO of Devine Capital Partners, advised executive candidates attracted by their clippers to keep their hair closely cropped, rather than completely shaved. “It is way too much image risk,” he said, “The best thing you can do in a business meeting is to make your look not an issue.”

      阅读下文,回答(1)~(5)题。

植物也有血型

      ①人们都知道动物有血液,且大多数颜色是鲜红的。但也有些动物的血液呈现出别种颜色,还有不同的血型。可你知道吗?从某种意义上讲,植物也有血液,那就是它的汁液。它们不仅有不同的颜色,并且令人称奇的是,植物也有血型!

      ②植物“血液”的颜色,有的是透明的,有的呈乳白色,有的与人血一样为鲜红色;有的呈流质状,有的很粘稠;有的香气扑鼻,有的臭味熏天。而植物也有血型,却是人们在一次偶然的机会中发现的。

      ③一天,一位日本妇女在家中死去,警察赶到现场,一时无法判断是自杀还是他杀,便进行血迹化验。经化验死者的血型为O型,可枕头上的血迹为AB型,遂怀疑是他杀。可是后来一直找不到凶手作案的佐证。于是有人提出,会不会枕头里的荞麦皮也有血型呢?经过化验,荞麦皮的血型果然为AB型。

      ④据科学家研究,蔬菜、水果也有血型,它们与人一样,也有A、B、O型的血型。经过研究发现,苹果、草莓、南瓜、山茶、辛夷等60种植物的血型为O型。在大约150种蔬菜、水果中,有血型的占19种。500余种植物种子中的60种有血型,其中,O型大约占一半,剩下的是B型或者是AB型,目前还没有发现有A型的。

      ⑤植物为什么会有血型呢?科学家研究证实,人和一些动物的红血球细胞膜表面有一种特殊的抗原物质,正是这种抗原物质不同的分子结构决定了血液的类型。而植物没有红色细胞,但它却有类似人体内附在红细胞表面的血型物质——血型糖。不同的血型糖便决定了不同的血型,这就是植物也有血型的奥秘所在。研究者还发现:植物的血型物质除了担当植物能量的储藏物外,由于本身粘度大,也担负着保护植物体的作用。

      ⑥科学家发现,在玉米、油菜和烟草等植物体中,含有类似于人体血红蛋白的基因。这表明植物也有造血功能!如果再把铁原子加入其中,就能够造出人体所需要的血红蛋白。血红蛋白是人体红细胞的重要组成部分,它易于与氧结合和分离,因此具有输送氧的功能。利用植物制造出人体所需要的血液,这种愿望如果能够成为现实,那么人类拥有的血库中的血就会取之不尽,而且安全性也会大大提高,不会携带艾滋病毒、肝炎病毒等人类血液中的有害物质。
