6 . Commencement (毕业典礼)is a time for idealism.

But economic reality is cruel everywhere; especially for new college graduates. They have been told repeatedly that a college degree is an open sesame (芝麻) to the global economy. But that’s not necessarily so, according to new research by two economists at the Massachusetts Institute of Technology, Frank Levy and Peter Temin.

It is true that people with college degrees make more money than people without degrees. The gap has narrowed somewhat in recent years, which is disturbing. But the earning power of college graduates still far outpaces that of less-educated workers.

The bad news, though, is that a college degree does not ensure a bigger share of the economic pie for many graduates. In recent decades Mr. Levy and Mr. Temin show, only college-educated women have seen their income grow in line with economy wide gains in productivity. The earnings of male college graduates have failed to keep pace with productivity gains.

Instead, a huge share of productivity growth, which expands the nation’s total income, is going to Americans on the top of the income scale. In 2005, the latest year with available data, the top 1 percent of Americans--whose average annual income was $1.1 million--took in 21.8 percent of the nation’s income, their largest share since 1929.

Administration officials, and other politicians and economists, often, believe that income inequality reflects an education gap. But Mr. Levy and Mr. Temin show that in the case of men, the average bachelor’s degree is not enough to catch the rising tide of the global economy.

They argue that the real reason that inequality is worsening is the lack of strong policies that broadly distribute economic gains. In the past, for example, a more progressive income tax and unions promote equality. Positive measures have also helped and probably accounts, in part, for the pay growth of college-educated women. But such measures have been eroding and new ones have not yet emerged, making the income gap even greater.

Mr. Levy and Mr. Temin conclude that only a new government policy can restore general prosperity. That’s a challenge to the nation’s leaders and today’s graduates. America needs them to contribute to the development of the nation in a global economy.

7 . For the most part, American children aren’t great at math. But Chinese children tend to be excellent. It’s consistently found Chinese students at the top of the academic pile and Americans much nearer the bottom.

In Lenora Chu’s book “Little Soldiers: An American Boy, a Chinese School”, she begins to reveal the cultural differences that lead to this gap. The differences she notices in children’s focus and discipline are dramatic, but she also notices cultural differences that influence how Chinese schools are run, and the reason why its students test so well. Along with factors such as highly trained teachers and an emphasis on memorizing before pursuing deeper understanding, the difference comes down to a belief that has begun slowly making its way across the US: achievement is the result of hard work, not natural ability.

This approach comes from a firm belief that anything is possible with hard work, with chiku, or “eating bitter”. Studies show that for kids who score poorly. Chinese teachers believe a lack of effort—rather than of smarts — is to blame.

Stanford psychologist Carol Dweck, author of “Mindset (心态)”, is responsible for making up the terms “growth mindset” and “fixed mindset”. Chinese students are trained to have a growth mindset: if they aren’t doing well, they’11 work harder, and they’ll be successful. American children tend to be trained to have a fixed mindset about academics: their abilities are largely predetermined and static. If they aren’t doing well, it’s because they’re not good at it.

In America students are told that learning is fun and easy. But real learning is actually very difficult and takes suffering and anxiety. If you’re not willing to go through that you’re not going to learn deeply. The downside is these students often give up when something gets hard or when it’s no longer fun.

How is everything going?

9 . The sixth mass extinction is not a worry for the future. It’s happening now，much faster than previously expected，and it's entirely our fault，according to a study puhlished Mooday.

Humans have already wiped out hundreds of species and pushed many more to the brink of extinction through wildlife trade，pollution，habitat loss and the use of toxic substances. The findings published in the scientific Journal Proceedings of the National Academy of Sciences( PNAS)show that the rate at which species are dying out has accelerated in recent decades.

Gerardo Ceballos González，a professor of ecology at the National Autonomous University of Mexico and one of the authors of the study，said approximately 173 species went extinct between 2001 and 2014. “173 species is 25 times more extinct species than you would expect under the normal extinction rate. ”he told CNN in an email. He and his team found that in the past 100 years，more than 400 vertebrate(脊椎动物的)species went extinct. In the normal course of evolution，such extinctions would have taken up to 10，000 years，they said.

Mass extinctions are just as severe as their name suggests. There have been five mass extinction events in the Earth’s history，each wiping out between 70％and 95％of the species of plants，animals and microorganisms. The most recent，66 million years ago，saw dinosaurs disappear. The past events were caused by catastrophic changes of the environment，including massive volcanic eruptions or collision with an asteroid.

The sixth mass extinction the one happening now—is different：scientists say it’s caused by humans. The researchers also said the current coronavirus(冠状病毒)crisis shows people’s recklessness(鲁莽)towards nature can seriously hurt themselves. Many endangered species are dying in large numbers due to the trade in wild animals and plants.

10 . A first-year undergraduate student in Chengdu, recently complained online that her mother refused to raise her monthly allowance to 4,500 yuan ( $ 633) even when she said her current allowance 2, 000 yuan was not enough to cover her expenses, sparking a debate on how much money a college student needs per month. One expert shares his views on the issue with China Daily: Students should pursue education, not comfort.

Even for a college student studying in a first-tier city in China, 2,000 yuan is enough to cover all his or her monthly expenses. In fact, for a college student in Chengdu a monthly allowance of 2,000 yuan is more than enough. According to a survey conducted by a bookkeeping platform, the average monthly expense for an undergraduate in cities other than Beijing, Shanghai and Hangzhou was less than 2,000 yuan in 2019； for Chengdu, it was 1,900 yuan.

Claiming that she can hardly afford new clothing and cosmetics with her 2,000 yuan monthly allowance, the undergraduate student in Chengdu criticized her mother for refusing to raise her pocket money. Her "meager" allowance, she said, prevented her from buying branded goods that her hostel-mates enjoyed.

By the time a person enters a college, she or he should have developed a healthy consumption habit. And a youth should adjust her or his consumption according to her or his family income. On a deeper level, the money they spend in college should depend on how much they value their parents' hard work. Besides, some college students could take UP part-time jobs to meet their monetary needs if they feel their parents don't or can't send them enough money. In this way they can also learn to meet the requirements of life in the future and develop healthy consumption habits. More importantly, they should always bear in mind that education is their top priority in college
