How much is a child's future success determined by born intelligence? Most guess around 25 percent, even 50 percent. 1. So if IQ is only a minor factor in success, what is it that separates the low earners from the high ones?
Science doesn't have a definitive answer, although luck certainly plays a role. But another key factor is personality. Financial success was correlated with conscientiousness, a particular quality in your personality marked by diligence, perseverance and self-discipline.
Grades at school and achievement-test results were markedly better predictors of adult success than raw IQ scores. 2.After all, don't they all measure the same thing? Not quite. Grades reflect not just intelligence but also " non-cognitive skills ", such as perseverance, good study habits and the ability to collaborate. Personality counts.
3. A research suggests childhood interventions （介入）can be helpful, and that conscientiousness is more malleable （可塑的）than IQ. Openness—a broad quality that includes curiosity—is also connected to test scores and grades.
4.Someone with an IQ of 70 isn't going to be able to do things that are easy for a person with an IQ of 190. But many people fail to break into the job market because they lack skills that aren’t measured on intelligence tests. They don't understand how to behave with kindness in job interviews. 5. Or on the job, they make it obvious they'll do no more than the minimum, if that.
A.IQ still matters, of course.
B.That might seem surprising.
C.They may show up late or fail to dress properly.
D.How much difference between people's incomes can be tied to IQ?
E.But the data suggest a much smaller influence： about 1 or 2 percent.
F.The higher the better for IQ, and perhaps for conscientiousness as well.
G.Success depends not just on born ability but on skills that can be taught.
Lego is considering a brick rental scheme in an attempt to cut down on plastic waste. The Danish toymaker has promised to make all its bricks from sustainable （可持续的） sources by 2030 and is ploughing significant resources into finding alternatives.
Tim Brooks, vice-president responsible for sustainability, said the company was "totally open" to the idea of a product rental scheme but acknowledged that lost pieces could cause a significant problem. He said the rental scheme was "possible" but admitted there were some "technical barriers", one of which is the complexity of some Lego kits （配套元件），many of which contain thousands of pieces.
" What are the chances of giving them to an eight-year-old child and getting them all back again?” Mr Brooks added. "There is a lot of technical thinking that needs to be done.
We are right at beginning of that.” Mr Brooks said Lego was exploring several ideas with a view to producing the highest value from products while consuming the least amount of resources. He said many would "probably never see the light of day” and there was no current plan to try a rental scheme.
Lego has come under increasing pressure to reduce its carbon footprint amid growing international alarm about the impact of plastic waste on the environment. It manufactures 19 billion pieces per year—36,000 a minute——that are made only of plastic while much of the internal packaging is also plastic.
So far, the only breakthrough has been the development of a line of bricks made from plant-based plastic sourced from sugarcane. The green trees, plants and flowers were first included in Lego sets late last year but account for only one-two percent of the total amount of plastic elements produced. Henrik Ostergaard Nielson, a production supervisor in Lego's factory in Billund, told the New York Times last year： "We need to learn again how to do this”
1.How will Lego cut down on plastic waste?
A.By considering a brick rental scheme.
B.By producing a new kind of toys instead of bricks.

D.By investing large amounts of money into market.
2.What does Tim Brooks expect of the product rental scheme?
A.It'll cause certain serious problems.
B.It'll be of great complexity.
C.It'll require more mature technical skills.
D.It'll involve much more kits of bricks.
3.What does the underlined word “many” in Paragraph 3 refer to?
A.Ideas. B.Values.
C.Products. D.Resources.
4.What can be inferred from the passage?

Today, China has conducted its first 3D printing experiment in space in a newly launched spacecraft, which was put into low-Earth orbit by China's Long March 5B heavylift carrier rocket.
Video broadcast on CCTV showed that the printer has printed a flat section of a honeycomb-shaped （蜂巢状）structure as well as a symbol of China Aerospace Science and Technology Corp, the parent company of the China Academy of Space Technology. The experiment was done by a 3D printer, developed and built by its Beijing Spacecrafts Manufacturing Factory, inside the prototype of China's new — generation manned spacecraft.
The printer, named the Space-Based Composite Material 3D Printing System, uses carbon fiber-reinforced materials to autonomously print objects. It is installed in the reentry module of the experimental spaceship, and will be brought back to Earth once the module returns.
The printer features advanced technologies in material modeling, precision control and automation. Once the space-based 3D printing technology becomes operationally ready, it can extensively benefit space programs as astronauts can use it to manufacture a lot of things they currently need to obtain from resupply flights by cargo spacecraft.
Wang Yanan, editor-in-chief of the Aerospace Knowledge magazine, said the 3D Printer will be very useful in extended space missions, such as those in a space station, because it will allow astronauts to make components quickly and conveniently in space. The technology will save future space journeys considerable resources and costs.
In fact, the device is not the only representative of 3D printing onboard the Prototype.
A CubeSat deployer, designed and made through 3D printing by CoSats Space Technology, is also carried by the spacecraft to check the adaptability of 3D-printed equipment in space. CoSats Chief Operating Officer Bai Ruixue said the 3D-Printed deployer is much lighter and stronger than its counterparts and it will have huge Potential in the space industry.

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
