Why is this？ Although the total growth rate of the world population will decrease(下降), in some countries there will be a big rise in the population. More people will be born in Third World countries than in the richer Northern countries. So the population will grow faster in poor countries; and the problems in these countries will be very serious. This is because the family is more likely to survive(幸存) if there are a lot of children to work for the members who become old or who cannot find work. A survey of the UN also shows that the growth rate is low where there is a higher level of income, better education, more health care and better living conditions. In this aspect, government plays an important role. So, the conclusion of the UN report is: "Look after the people and the population will look after itself." What can we learn about the growth rate of population？ A．The total growth rate of world population will increase. B．The growth rate of population in richer countries will increase. C．The growth rate of population in poor countries will increase. D．The total growth rate in American countries will increase.

We rose tint our memories and put ourselves into self-affirming situations. We become defensive when criticized, and apply negative stereotypes to others to boost our own esteem, we stalk around thinking we’re hot stuff. Psychologist and behavioral scientist Nicholas Epley oversaw a key studying into self-enhancement and attractiveness. Rather that have people simply rate their beauty compress with others, he asked them to identify an original photogragh of themselves’ from a lineup including versions that had been altered to appear more and less attractive. Visual recognition, reads the study, is “an automatic psychological process occurring rapidly and intuitively with little or no apparent conscious deliberation”. If the subjects quickly chose a falsely flattering image- which must did- they genuinely believed it was really how they looked. Epley found no significant gender difference in responses. Nor was there any evidence that, those who self-enhance the must (that is, the participants who thought the most positively doctored picture were real) were doing so to make up for profound insecurities. In fact those who thought that the images higher up the attractiveness scale were real directly corresponded with those who showed other makers for having higher self-esteem. “I don’t think the findings that we having have are any evidence of personal delusion”, says Epley. “It’s a reflection simply of people generally thinking well of themselves’. If you are depressed, you won’t be self-enhancing. Knowing the results of Epley ‘s study,it makes sense that why people heat photographs of themselves Viscerally-on one level, they don’t even recognise the person in the picture as themselves, Facebook therefore ,is a self-enhancer’s paradise,where people can share only the most flattering photos, the cream of their wit ,style. ,beauty, intellect and lifestyle. it’s not that people’s profiles are dishonest,says catalina toma of Wiscon—Madison university ,”but they portray an idealized version of themselves.
