下列地理现象与太阳辐射关系较密切的是

①生物的生长    ②大气的运动    ③火山的爆发   ④煤、石油的形成

A.①②③

B.②③④

C.①②④

D.①③④

答案

答案:C

太阳光线到达地球的时间大约需要8分钟,日地平均距离为1.5亿㎞。太阳直接为地表提供光能和热能,维持地表温度,为生物繁衍生长,大气和水体运动等提供能量,太阳能是一种新能源。火山的爆发是由于地球内力作用的原因,与太阳辐射无关。所以本题选择C选项。

Next time a customer comes to your office, offer him a cup of coffee. And when you’re doing your holiday shopping online, make sure you’re holding a large glass of iced tea. The physical sensation of warmth encourages emotional warmth, while a cold drink in hand prevents you from making unwise decisions-those are the practical lesson being drawn from recent research by psychologist John A. Bargh.

Psychologists have known that one person’ s perception of another’ s "warmth" is a powerful determiner in social relationships. Judging someone to be either "warm" or "cold" is a primary consideration, even trumping evidence that a "cold" person may be more capable. Much of this is rooted in very early childhood experiences, Bargh argues, when babies’ conceptual sense of the world around them is shaped by physical sensations, particularly warmth and coldness. Classic studies by Harry Harlow, published in 1958, showed monkeys preferred to stay close to a cloth "mother" rather than one made of wire, even when the wire "mother" carried a food bottle. Harlow’ s work and later studies have led psychologists to stress the need for warm physical contact from caregivers to help young children grow into healthy adults with normal social skills.

Feelings of "warmth" and "coldness" in social judgments appear to be universal. Although no worldwide study has been done, Bargh says that describing people as "warm" or "cold" is common to many cultures, and studies have found those perceptions influence judgment in dozens of countries.

To test the relationship between physical and psychological warmth, Bargh conducted an experiment which involved 41 college students. A research assistant who was unaware of the study’s hypotheses, handed the students either a hot cup of coffee, or a cold drink, to hold while the researcher filled out a short information form: The drink was then handed back. After that, the students were asked to rate the personality of "Person A" based on a particular description. Those who had briefly held the warm drink regarded Person A as warmer than those who had held the iced drink.

"We are grounded in our physical experiences even when we think abstractly." says Bargh.

We can infer from the passage that().

A. abstract thinking does not come from physical experiences

B. feelings of warmth and coldness are studied worldwide

C. physical temperature affects how we see others

D. capable persons are often cold to others
