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
1.What's the expert's attitude to the issue about the undergraduate student?
A.He was critical.
B.He was neutral.
C.He was supportive.
D.He was unconcerned.
2.In 2019, the undergraduates' average monthly expense in Hangzhou was
A.more than 2,000 B.633 dollars
C.less than 2,000 yuan D.1,900 yuan
3.Which of the following best explains “meager” in paragraph 3?
A.Empty. B.Pitiful.
C.Mean. D.Fruitful.
4.What does the last paragraph mainly talk about?
A.College students should keep their expenses in line with their family conditions.
B.College students consumption level is determined by their parents.
C.College students should take up a part-time job to cover their expenses .
D.College students should deal with their living expenses problems reasonably.

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.
1.What did the video broadcast on CCTV show to the audience?
A.The process and the products of the 3D printing.
B.The name and the shape of the 3D printer.
C.The significance of the 3D printing technology.
D.The relationship between the two companies.
2.What if a component is broken in the space station now?
A.It has to be sent by spaceship back to earth for repair.
B.The astronauts can fix it conveniently by hand on the spot.
C.The astronauts make one using 3D printing and replace it.
D.It has to be unloaded and abandoned in space.
3.Why is the last paragraph mentioned?
A.To introduce the CubeSat deployer produced in space.
B.To explain the advantages of the 3D printing in space.
C.To show the adaptability of 3D printing in space.

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.
C.By replacing common plastic with a renewable material.
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?
A.Lego has to explore a new product to earn a profit.
B.A brick rental scheme has been put into mass production.
C.plant-abased plastic is environmentally friendly.
D.Lego is optimistic about the brick rental scheme.

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.

Through our lives, we can gain a lot and lose so much. But being honest should always be with us, as honesty is always regarded as a virtue. Every time I talk about the topic, something crowds in my mind as if it had just happened.
I was 16 when one morning, Dad told me I could drive him to Mijas and then take the car in a nearby garage to get it serviced. At that time, I had just passed the driving test, and I hardly had a chance to use the car, so I said yes without hesitation.
I drove my father to Mijas, promising to pick him up again at 4 pm, then I went to a
nearby garage, and put the car in there. Since I had several hours to spare, I decided to go to a movie theater near the garage to see the movie. However, I was so absorbed in the plot of the movie that I forgot the time. When the last movie finished, I looked at my watch： 6 pm. I was two hours late!
I thought my father would be very angry if he knew what I was doing. And he would never let me drive again. So I decided to make up an excuse. Then, I drove to the appointed place, my father was sitting in a corner, waiting patiently. I first apologized for being late, then told him that I wanted to get there as soon as possible, but that something was wrong with some of the main parts of the car.
I would never forget the way he looked at me. “I'm very disappointed that you thought you had to lie to me, Jason.” My father looked at me again and said, “When you didn't show up on time, I called the gas station and asked if there was anything wrong They told me you never picked up the car. So, you see, I know there's nothing wrong with the car at all."
Paragraph 1
A wave of guilt swept over me and I had to admit the fact that I had gone to the movies and that was the real reason why I was late.

Paragraph 2
But father, it's exactly eighteen miles home from here , and it's dark. You can't walk back. " I begged.
