B
Aging brings wrinkles, sagging bodies and frustrating forgetfulness. But getting older is not all bad for many people. Mounting evidence suggests aging may be a key to happiness. There is conflicting research on the subject, however, and experts say it may all boil down to this: Attitude is everything.
Older adults tend to be more optimistic and have a more positive outlook on life than their younger and stressed opposites. The big question is why seniors are happier. A recent study suggests one reason: Older adults remember the past through happy memories. Aging can bring more cheer as people become more comfortable with themselves and their roles in society. The older adults said they were enjoying more time with their family, spending more time on hobbies and having greater financial security and did not have to work.
But others are doubtful about the link between happiness and growing older.
"The notion that those in old age are happiest is misleading," said Richard Easterlin, a professor of economics at the University of Southern California. "It is based on comparing people of different ages who are the same in terms of income, health, family life." Easterlin added, "When you take account of the fact that older people have lower income than younger, are less healthy, and more likely to be living alone, then you will find it hard to accept that they are happier.
In fact, scientists have found that as people age, their health declines and social networks disappear as their friends die, which can make the elderly less happy.
Even if one does give in to age's dark side, health and happiness don't always go hand-in-hand. It's all about attitude. Research by the University of Chicago’s Yang suggests that attitude about life and happiness, is partly shaped by the era in which a person was born. It turns out that individuals who adapt the best to changes also have the highest expected levels of happiness.
Despite the conflicting findings about aging and happiness, the good news is that there doesn’t appear to be a limit to how much happiness one can achieve in one’s life. “Most people desire happiness,” Easterlin said. “To my knowledge, no one has identified a limit to attainable happiness.”

文章大意:本文是一篇说明文。文章介绍了“成长心态”,以及每个人实际上都是固定心态和成长型心态的混合体,并随着经验不断进化;我们要让孩子更适应或大或小的失败。

【推荐1】I used to tell my children that they were smart, because I was impressed by their rapid growth. I remember clearly watching my daughter figure out how to build a Lego house that would stand up on its own, and thinking: Look at this tiny architectural genius.

But decades of research now suggest that we should not tell our children they’re “smart” when they do impressive things. When I first heard it, I felt instinctively irritated. But after I dug into the research, I was persuaded. It all goes back to something called “growth” mindset, a term developed and popularized by Carol Dweck, a professor of psychology at Stanford. Professor Dweck believes that we can change our abilities through effort and strategy. The alternative to a growth mindset is a “fixed” mindset — the idea that our abilities are inborn and can’t be changed. When we praise our children for being “smart”, based on victories like doing well on a test, we’re unwittingly (不知不觉地) encouraging them to believe that if they do poorly or make mistakes, they’re not smart.

It’s not just what we say that matters, but how we tolerate our children’s failures. A 2016 study by Dweck showed that parents’ “failure mindsets” affect their children more than their views on intelligence. In other words, if parents think that failure is shameful, their children are more likely to be afraid of making mistakes. The study concludes that everyone is actually a mixture of fixed and growth mindsets, continually evolving with experience. Whatever we say or don’t say to our kids, the key is to get them more comfortable with failures big or small.

It’s helpful for kids to understand that you make mistakes and learn how they happen. When you chat with them, you can describe what you learned, or how you strategized a solution. “You don’t have to deny you have negative emotional reactions,” Dweck said. “We, as a society, don’t do that enough because we feel embarrassed when we make mistakes.” But if we discuss our missteps more and explain how we overcame them, our children can learn to do the same.

1. How did the author feel about the research advice at first?
A.It was confusing.B.It was annoying.
C.It was persuasive.D.It was encouraging.
2. What do the children with a growth mindset tend to believe?
A.Smartness is the key to success.
B.Difficulties in daily life teach them a lot.
C.Their abilities can be improved through hard work.
D.They are impressive due to their good grades on tests.
3. What does Dweck suggest parents do?
A.Help children face failures positively.
B.Hide their negative feelings from children.
C.Remind children to avoid making mistakes.
D.Pay attention to developing children’s intelligence.
4. Which of the following is a suitable title for the text?
A.Ways to Cultivate Smart Children
B.The Effect of a Fixed Mindset on Children
C.The Power of Proper Praise for Children’s Growth
D.The Importance of a Growth Mindset in Parenting

【推荐2】To help the environment, many Americans have made the change from paper and plastic(塑料的) bags to reusable shopping bags. But a report by a Florida newspaper says that reusable shopping bags sold by some supermarkets have high levels of lead (铅), which can be dangerous to humans, especially young children. Now, there's a call for a rethink about the use of reusable shopping bags.

“When our families go to the store looking for safe and healthy foods, the last thing they should be worrying about is a bag,” Charles Schumer, a government official said.“Quick and complete research will allow everyone to make right decisions.”

The newspaper bought more than a dozen bags sold at Publix supermarkets from Florida supermarkets to test them for lead. The results showed that certain bags had lead levels that worried health officials. Some bags had enough lead in them to be considered dangerous waste if people were to throw the bags out with other rubbish. Lead in the bags may not move onto food. But over time, paint on the bags can break off and the bags can wear out. When this happens, lead can be freed.

The bags with the highest levels of lead had beautiful designs and many pictures. Plain(朴实无华的) reusable bags without them are found to have little lead. People worried about lead levels in reusable bags can turn to cloth. Paper bags are also a good choice, since paper can be reused.

1. What worries people now is that reusable shopping bags ________.
A.can't be reused.B.can be a danger to people.
C.are a waste of money.D.are as bad as paper bags.
2. Lead in shopping bags will probably come out when ________.
A.the paint is separated from themB.they are thrown away
C.food is put in themD.they are put with other rubbish
3. What's the best title for the text?
A.The return of paper bags
B.Time to invent greener shopping bags
C.The harm of lead
D.Be careful with reusable shopping bags

文章大意:本文是一篇说明文。文章介绍了一种将大脑信号直接转化为图像的新的方法。

【推荐3】Several research groups have previously generated images from brain signals using AI models that require numerous data analysis. Now, Shinji Nishimoto and Yu Takagi at Osaka University in Japan have developed a much simpler approach by slightly adjusting Stable Diffusion, a popular text-to-image generator, allowing it to turn brain signals directly into pictures.

Shinji Nishimoto and Yu Takagi built two additional models to help make Stable Diffusion work with brain signals. The pair used data from four people obtained by using functional magnetic resonance imaging (fMRI) (功能磁共振成像技术) to scan their brains while the four were viewing 10,000 pictures.

Using around 90 percent of the brain-imaging data, the pair then trained one model to make links between fMRI data from a brain region that processes visual signals and the images that people were viewing. They used the same dataset to train the other model to form links between text descriptions of the images and fMRI data from a brain region that processes the meaning of images. After training, these two models could translate brain-imaging data into forms that were directly fed into the Stable Diffusion model. It could then reconstruct around 1000 of the images people viewed with about 80% accuracy. This level of accuracy is similar to that previously achieved in a study that analysed the same data using a much more tedious approach, which involved more time and efforts.

However, the study only tested the approach on four people. “This approach requires huge fMRI machines”, says Sikun Lin at the University of California. “In future, more practical versions of the approach could allow people to make art or change images with their imagination, or add new elements to gameplay, but it is still a long way from daily use,” she says.

1. What do we know about Stable Diffusion?
A.It calls for more data analysis.
B.It was created to read brain signals.
C.It was launched by Japanese scientists.
D.It helps change brain signals into pictures.
2. What are the two models intended to do after training?
A.To process data.B.To redraw images.
C.To scan human brains.D.To match text descriptions.
3. What does the underlined word “tedious” mean in paragraph 3?
A.Simple.B.Complicated.C.Effective.D.Convenient.
4. What does Sikun Lin say about this approach?
A.It is practical for daily use.
B.It has been widely used in art.
C.It will enrich people’s imagination.
D.It will be applied in a broad range.
