Some of the most famous scientific discoveries happened by accident. From the microwave oven to penicillin, scientists trying to solve a problem have sometimes found unexpected things. This is exactly how we created phosphorene nanoribbons (磷烯纳米带) — a material made from one of the universe’s basic building blocks, which has the potential to revolutionize a wide range of technologies.
We'd been trying to separate layers of phosphorus crystals (晶体) into two-dimensional sheets. Instead, our technique created tiny ribbons one single atom thick and only 100 or so atoms across, but up to 100,000 atoms long. We spent three years improving the production process, before announcing our findings. The two-dimensional ribbons have a number of remarkable properties (属性). Their unbelievable width allows their properties, such as whether and how they conduct electricity, to be controllable. They are also very flexible, which means that they can follow any surfaces they’re put on perfectly, and can even be twisted.
More than 100 scientific papers predicted the transformative potential of these ribbons, should it be possible to create them, across a range of technologies — some as many as five years before the publishing of our discovery in Nature. Perhaps the most important of these is in the area of battery technology. The structure of phosphorene nanoribbons means that the charged ions (带电离子) that power batteries could soon move up to 1000 times faster than they currently possible do. This would mean a significant decrease in charging time, alongside an increase in capacity of approximately 50%. Such performance gains would provide massive boosts to the electric car and aircraft industries, and allow us to use renewable energy more readily, even on grey, calm days.
1.What does “we” in the text refer to?
A.Scientists. B.Doctors.
C.Publishers. D.Technicians.
2.What can we know about phosphorene nanoribbons in Paragraph 2?
A.Its shape. B.Its origin.
C.Its structure. D.Its characteristic.
3.What would reduce charging time according to the scientific papers?
A.The cleaner source of energy.
B.The bigger batteries of tiny ribbons.
C.The increasing capacity of batteries.
D.The faster moving speed of charged ions.
4.What does the text mainly introduce to us?
A.The amazing development of battery technology.
B.Significant changes brought by wonderful discoveries.
C.A “Wonder material” created accidentally by scientists.
D.Unexpected inventions made in human’s history.

On Tuesday, China announced it had grown the first ever plants on the moon, days after landing on the moon’s “far side” Von Karman crater. The cotton seed sprouts (新芽) seemed to have withstood the tough lunar conditions: freezing temperatures, lower gravity levels, and radiation.
But by Thursday, the new cotton seed sprouts had dead already, according to Liu Hanlong, the experiment leader, in a government press conference statement.
After Chang’e-4 landed on the far side of the moon earlier this month, the probe (探测器) was sent a command to remotely water the plants and start the growing process. A tube directed natural light on the surface of the moon into the small container to allow the plants to grow. The probe entered a sleep mode on Sunday, the first lunar night after the probe’s landing.
Professor Xie Gengxin, professor at Chongqing University and chief designer of the experiment, told CNN that it ended after nine days when the control team shut down the power. Xie said temperatures inside the biosphere had grown too abnormal and reached extremes that would likely kill all life, including the seeds and eggs during the lunar night. Xie didn’t confirm why temperatures had risen to levels unbearable for the plants in spite of the measures taken by the research team.
Even though the experiment was quickly terminated, Xie considered it a success. The cotton were the only seeds to sprout, however, and despite many assumptions about the future possibility of moon clothes, the cotton plant’s main purpose this time was to give researchers the valuable data on how to cultivate life in the moon’s tough conditions. The eventual ability to grow plants on the moon could prove useful for long-term space missions, like a trip to Mars. Astronauts could theoretically harvest their own food in space, avoiding the need to return to Earth to resupply.
Aside from the apparent failure of the biological or plant experiment, the rest of China’s mission to the far side of the moon appeared on track as of Thursday. The historic mission is intended to accomplish a range of tasks, including conducting the first lunar low-frequency radio astronomy experiment and exploring whether there is water at the moon’s poles.
Chang’e-4 is the latest step in China’s robotic lunar-exploration program, named after a moon goddess in Chinese mythology. China plans to launch the Chang’e-5 sample-return mission sometime this year.
1.What does the underlined word “withstood” mean?
A.Appreciated. B.Suffered from.
C.Tolerated. D.Been subject to.
2.What is the fourth paragraph mainly about?
A.The measures of the research team. B.The cause of ceasing the experiment.
C.The reason for the extreme temperature. D.The failure and impact of the experiment.
3.What is the major target of the plant experiment?
A.To make moon clothes possible.
B.To ensure its value for long-term space missions.
C.To enable astronauts to harvest their own food without returning to Earth to resupply.
D.To accumulate the priceless data on how to grow life in the moon’s severe conditions.
4.What is the best title for the text?
A.China’s moon plants have died
B.China’s mission to the far side of the moon
C.The Chang’e-5 sample-return mission
D.Astronauts’ efforts to cultivate life in the moon

The new garbage sorting regulation has taken effect in Shanghai starting from July 1. Many citizens are still confused about the classification of the four different types of trash. Thankfully, authorities have released an official guideline to explain the new rules.
The guideline, published by the Shanghai Greenery and Public Sanitation Bureau, provides a rather clear definition on the four kinds of waste: recyclable waste, harmful waste, household food waste and residual (剩余的) waste.
Harmful waste, as the name suggests, includes various poisonous materials like used batteries, light bulbs, out-of-date medicines, paint and pesticides.
Household food waste — which is translated to “wet trash” in Chinese — refers to food leftovers, rotten food, pet food, fruit peels, remains of TCM herbs (中药) and flowers.
Paper, plastic, glass, metal and textiles (纺织品) are counted as recyclable waste.
The definition of residual waste is a little confusing. Anything that is not listed above belongs to this category.
As specific as the new guideline is, residents still have a hard time sorting trash correctly and are finding it challenging to memorize them all. For instance, both plastic bottles and bubble tea or coffee cups are plastic materials. However, the former falls to the category of recyclable waste and the latter belongs to residual waste. To save the hassle, some netizens have come up with their own way to sort trash.
“We should do this from a pig’s angle,” commented one netizen. “Those edible (可食用的) for pigs are household food waste. Those even pigs don’t want to eat are residual waste. If a pig consumes something and dies of it, then something must be harmful waste. Those that can be sold and the money we gain can be used to purchase pigs are recyclable waste.”
The new regulation came into effect on July 1. Those who do not sort their trash properly will be fined RMB 200.
1.What do the old coats that you want to throw away belong to?
A.Harmful waste. B.Wet trash.
C.Recyclable waste. D.Residual waste.
2.What is the common point of “wet trash”？
A.They can be broken down easily. B.They all come from plants.
C.They all have bad smells. D.They all have poisonous materials.
3.What is the tone of the netizen like?
A.Serious. B.Humorous.
C.Delightful. D.Uncertain.
4.What does the passage mainly talk about?
A.The four sorts of garbage are forbidden in Shanghai.
B.Shanghai garbage sorting enforcement begins.
C.People are still confused about garbage sorting.
D.The netizens in Shanghai support the garbage sorting policy.

Experienced⁃Based Education
Everyone is familiar with traditional education. You sit in a class and a teacher teaches. This is an important part of development. But at some point, every individual has to take charge of their own education. To do this, one must look at the root of learning.1.
Basically, unfamiliar experiences usually add more value than experiences that are familiar.
2. And we are in a better state to learn something new. Honestly, someone who never experiences the same thing twice will never have a chance to benefit from anything learned. However, new experiences are generally what make people interesting and push them to grow.
High school is a new experience. College is a new experience. However, at some point traditional education becomes repetitive. It is not that you won’t learn anything else, but that the environment is so familiar.3.
To solve this, an individual needs to introduce new experiences into their life. You may spend a summer in a different part of the country or learn a new language through trial and error. You can also go to a drive⁃in movie（or some other entertainment event that is new to you）.4.
These types of experiences often result in very little“book knowledge”. Instead, they will often provide you with a better understanding of yourself as you experience your reaction to different situations.5. It can be invaluable for you to work effectively with others. Becoming a well ⁃ rounded human isn’t something that happens by accident. You can spend your entire lifetime developing your potential.
A.Has education changed so much in the last decade?
B.They will also provide you with a better understanding of others.
C.Those new experiences may not lead to great personal development.
D.These are all things that can stretch and expand your experience in life.
E.This is because unfamiliar experiences require much more of our attention.
F.As a result, you can easily become less aware of your experience and not learn as much.
G.What makes some experiences add great value to our lives while other experiences do not?

China and Western countries may have different cultural belief about certain animals. But when it come to pigs, we somehow reach an agreement which pigs are lazy, ugly, stupid and shameless. None of these words are exact positive to describe pigs. Therefore, the truth is that pigs have some good qualities. According to a paper publishing in 2017, pigs can tell from those who treat them well and those who don’t. Perhaps these are the qualities of pigs to keep it in mind - their intelligence, cuteness and patience. Besides, people born in the Year of the Pig were usually devoted to what they do. They have great sense of responsibility.
