According to psychology professor Carol Dweck of Stanford University, "Praising children for being smart can backfire." If this doesn’t get the attention of Millennium parents, I’m not sure what will.It is my observation that so many parents today believe that if their child appears to be the least bit "advanced" for his age, he’s destined to be the next Albert Einstein, Tiger Woods, or Bill Gates. It’s human nature for room and dad to show much admiration for their child and dish out praise for accomplishments achieved. The problem is, according to this study, parents may not be doing the best thing by praising their child for his intelligence.Dweck’s research involved junior high students in New York and concluded that "classroom performance improved when her study subjects believed the brain is like a muscle that can grow." Students who "focused on the learning process (effort, concentration or strategies used) asked for feedback and did better in all subjects." Feedback such as, "You did well because you worked so hard" or "You used so many descriptive words to make this story interesting" can encourage children to try new things, as they are being rewarded for their effort. When the "time and effort" strategy is being positively reinforced, the child will probably use the same strategy next time they are learning something. Over time new strategies can be introduced, so the child’s repertoire of strategies is broadened.Dweck goes on to say that "they (students who improved) performed better because their success was being measured by effort, not by test scores or grades." Parents should praise effort, not just results. Children who received praise about their innate abilities (talents or strengths) had less chance of trying new things and became anxious and under-performed as things became more difficult. That is one of the greatest dangers to continually praising children for whatever they do in order to falsely raise a child’s self-esteem.What are mom and dad to do Offer genuine praise and encouragement for efforts and successes, but balance this with setting appropriate expectations and following up with consequences when the child falls short due to laziness. Don’t make excuses. Your child will better face the challenges life has to offer in the future when you as a parent recognize the efforts he is making today. Which of the following can be considered proper feedback()

A. You did really well on this spelling test, you must have spent hour practising your words.
B. Oh, honey, you’re so smart--that failing grade won’t matter anyway.
C. This is a wonderful painting. What a great artist you are!
D. You did really well on this spelling test. You are very clever.

As a new matchmaker, Internet dating sites promise two cutting edges: a vastly greater choice of potential partners and scientifically proven way of matching suitable people together.The greater choice is unarguable. But does it lead to better outcomes And do the "scientifically tested methods" actually work These are the questions asked by a team of psychologists led by Eli Finkel.The researchers’ first observation is how any of the much-boasted partner- matching methods actually works. Many firms preserve their intellectual property as trade secrets, and there is no reason why Internet dating sites should not be among them. But this renders claims of effectiveness impossible to test objectively. There is thus no independent scientific evidence that any of these methods does enhance the chance of their hitting it off when they meet.It is possible to test the value of a claim that they match people with compatible personality traits. However, Dr. Dyrenforth asked more than 20,000 people about their relationships and assessed their personalities. Members of couples with similar personalities were indeed happier than those without. But the difference was just 0.5%.Surely, the chances of finding that magic other are increased by the second thing Internet dating brings: a multitude of choice. But here, too, things are not as simple as they might seem.An assumption behind all consumer decisions is that what people think they want is what they actually need. And the data suggest people are not good at knowing what they want. One of Dr. Finkel’s own studies showed that when they are engaged in speed dating, people’s stated preferences at the beginning of the process do not well match the characters of the individuals they actually like. When faced with abundant choices, people pay less attention to characteristics that require thinking and conversation to evaluate and more to physical matters. Choice, in other words, dulls the critical faculties.Finkel’s conclusion is that love is as hard to find on the Internet as elsewhere. You may be just as likely to luck out in the local caf~, or by acting on the impulse to stop and talk to that stranger on the street whose glance you caught, as you are by clicking away with a mouse and hoping that, one day, Cupid’s arrow will strike. According to Paragraph 6, the abundance of choices offered by the dating sites()

A. can increase the chance of finding ideal partners
B. helps people become better aware of what they want
C. diverts attention from other mental qualities
D. leads to exclusive concern with one’s appearance

When does a middle-aged man become an old man Officially, of course, it’s when we reach retirement age. But, as we all know, this is a fairly blunt (生硬的) method of decision making. As life expectancy (预期寿命) increases, retirement planning needs to be changed. This is because being an old man today is very different from what it was a generation or so ago.2. Sixty-five is the new middle-aged man. These days people are talking about the young-old, that is ages 70-75, and those over 75 as the old-old. The young-old frequently continue in good health and maintain strong links with friends and family. The old-old have a much higher chance of poor health and social isolation.3. Although men are living longer, there are still more old women than old men. This fact alone should arouse interest as to why. Relatively little is actually known about why this is the case or about the experiences of the old man. Sure, we are aware that the old man experiences anxiety, financial problems, loneliness, etc., but that’s really about all we know.4. It is usually believed that the old man often complains about their health. In fact, most rate their health as good even though most are diagnosed with at least one chronic illness. The physical health of the old man is strongly affected by their health behavior when they were younger. More research should be done on the experiences of ______.

42()

A. exotic
B. patriotic
C. supersonic
D. alcoholic
