Judgment of character can be influenced by somehting as simple as the temperature of a drink held in our hands .according ot a US study published today,.

Researchers form Yale University conducted experiments that showed that people perceive(认知)others as more generous and more attentive if they have just been holding a hot cup of coffee,and that the inverse is true for cold drinks.    

A second study found that people are more likely'to give somethine to others if they held.

something warm, and more likely take something for themselves if they something cold, In the study .published in the current issue of the journal Science, the research team built on earlier studies that show the physical distance between indivduals also influences social judgment about others.

The experiment suggests that the warmth of an object or the distance that is felt between people means more than simple metaphors(暗喻).Both instances, researchers said ,are literal examples of trust first experienced between motehr and child during infancy.

“When we ask whether someone is a warm person or cold person。they both have a temperature 0f 98.6(Farenheit,37 Celsius),’’said Yale psychology professor John Bargh,who co-authored the study with Lawrence Williams at the University of Colorado.“These terms indirectly explains the primitive experience of what it means to be warm and cold·’’

“Physical temperatures affect not just how humans see each other,but also how humans behave,”said Bargh,“The power of temperature on character assessments has been backed up by recent brain imaging studies.”He added.“Physical warmth call make us see others as warmer

people,         cause us to be warmer,more generous and trusting as well

The study was funded by the National Institutes of Health.

76.What is the main idea ofthe passage?(Please answer within 15 words.)

79.Mlich sentence in the text is the closest in meaning to the following one?

Recent studies on brain imagin ghas supported temperature's effect on judgment of character

80.Translate the underlined sentence in Paragraph 3 into Chinese.

答案

Temperature and distances can affect judgement of character 。/ a cup of hot coffee can affect judgement of character 。

1)physical temperatures   2)the physical distance between individuals  

But also     

the power of temperature on character assessments has been backed up by recent brain imaging studies。

80.另一项研究发现,如果人们手里拿着暖和的东西,那么他们更乐于给予;相反,如果人们手里拿着冰凉的东西,那么他们将会索取。

单项选择题

阅读下面短文,回答下列问题。
人体干细胞
人类胚胎干细胞是人类胚胎发育早期——囊胚中未分化的细胞。囊胚外表是一层扁平细胞,可发育成胚胎的支持组织如胎盘等;中心的腔称为囊胚腔,腔内侧有内细胞群。内细胞群在形成内、中、外三个胚层时开始分化,内胚层分化形成肝、肺和肠等,中胚层分化形成骨骼、血液和肌肉等,外胚层分化形成皮肤、眼睛和神经系统等。由于内细胞群能发育成完整的个体,因而这些细胞被认为具有全能性。
成人身上也有干细胞,主要分布于骨髓、血液、大脑、胰腺等处,比如骨髓和血液中就有造血干细胞。但是,这些成年干细胞非常稀少,较难分离和纯化。它们的作用基本上是确定的,例如骨髓中的造血干细胞在体内环境下的使命就是分化成各种血液细胞。虽然近年来发现成年干细胞也具有一定的可塑性,例如在体外培养时,可通过改变条件让骨髓干细胞分化成神经细胞,但是目前还未发现成年干细胞能像胚胎干细胞那样具有分化出所有类型细胞的能力。同时,成年干细胞在体外扩增达三四百代。因此生物学家们普遍认为胚胎干细胞的研究更有价值,美国生物学家戴利说:“20世纪是药物治疗的时代,21世纪则是细胞治疗的时代。”
目前,胚胎干细胞研究丛一个重点是用来产生神经细胞,以修复受损伤的神经系统。美国霍普金斯大学一个实验室用病毒感染老鼠的脊髓神经,使之瘫痪,然后从人的胚胎组织分离出来干细胞,在体外培养一段时间后,再注射到瘫痪老鼠的脊髓中。三个月后经过治疗的老鼠能蹒跚走路,而未经治疗的老鼠依然故我。解剖结果显示,这些来自人类胚胎的干细胞已经布满了老鼠的脊髓,并具有成熟的神经细胞的特征。
胚胎干细胞另一个研究重点是用于产生能分泌胰岛素的胰腺组织,再将这些胰腺组织移植到体内,以根治糖尿病。去年西班牙的研究者就将胰岛素基因转入小鼠的干细胞中,使之具有分泌胰岛素的能力,再将这些干细胞植入患糖尿病的小鼠胰腺中,结果小鼠的糖尿病症状消失了。
胚胎干细胞还有多种可能的用途。不过,医学界的美梦还需要一段时间才能变成现实。
胚胎干细胞分化的组织是否会在人体内无限度地增殖,甚至形成肿瘤,科学家必须小心提防,以免未得其利,先受其害。而分离干细胞必须“杀死”胚胎,这是否属于谋杀,也正在成为媒体和饭桌上争吵不休的话题。

下列理解不符合原文意思的一项是:

A.造血干细胞和骨髓干细胞都属于成人身上的成年干细胞。

B.成年干细胞在体内的分化方向是确定的,在体外培养时其分化方向则是不确定的。

C.所谓“细胞治疗的时代”,主要是指利用胚胎干细胞治疗疾病的时代。

D.利用胚胎干细胞产生能分泌胰岛素的胰腺组织以治疗糖尿病,已取得初步研究成果。
