1 . There was a point in time when the solar industry was considered dead money. It was too expensive, too inefficient, and too inconsistent to be a viable (切实可行的) alternative energy source for really anything, let alone your home or office.
But those days are long gone.
Solar energy costs have dropped more than 70% over the past 10 years, and are now cheaper than fossil fuels in most parts of the United States. Better yet, the drivers of these cost declines — economies of scale (规模经济) and technological improvements — are durable (耐久的) , and therefore, solar is only going to get even cheaper. Indeed, these forces are so powerful in the solar industry that they have their own law — Swanson’s Law — which states that the price of solar modules (模块) decreases by about 20% for every doubling in global solar capacity.
Meanwhile, solar panels have become very efficient at transforming light from the sun into usable energy. Back in 1992, researchers at the University of South Florida made a thin-film solar cell with 15.9% efficiency — and that was considered a breakthrough at the time.
These days, though, your average silicon solar cells’ efficiency rate is around 20%. That’s standard. And some research efforts have even managed to achieve near 50% efficiency in certain lab tests.
At the same time, these solar systems have become dramatically more consistent. One of the biggest hurdles for solar in the early 2000s was its intermittency — the sun doesn’t shine every day, so what do you do when its cloudy?
Well, that’s why the clean energy industry has developed energy storage solutions, which are basically just big batteries that homeowners and office building managers can install on-site and link to their solar panels to store excess (过度的) solar power on super sunny days, and use that power on cloudy days.
Cheapest. Most efficient. Most consistent. That’s a powerful combination. No wonder solar industry has accounted for 58% of all new energy capacity additions so far in 2021 and is only going to get stronger and more active over the next 10 years — to a point where, by 2030, I wouldn’t be surprised to see solar industry accounting for 90%+ of all new energy capacity additions.

2 . Very few people can say that they have achieved all that they are capable of. But what is it that is preventing you from fulfilling your potential (潜能)?
It is easy and natural to settle into a rut (墨守成规). Why try something new when you are already doing that you are good at?

4 . Despite an ever-higher bar to grab the attention of students in large lecture hall, Tatiana Erukhimova, who teaches physics at Texas A&M University, has managed to get her students, as well as future generations, excited about the science.
Known as “Dr. Tatiana”, the professor performs physics tricks with boundless energy and enthusiasm in her videos. A range of everyday objects are used in her experiments, from pingpong balls and toilet paper to marshmallows, bicycle wheels and hair dryers. Videos of her dramatic demonstrations have received hundreds of millions of views across social media platforms.
However, things aren’t always easy. When she first started teaching college freshman classes two decades ago, she also struggled to grab the attention of her students. “I did not grab their attention on the first day-that was my mistake.” she says. “I missed this opportunity to bond with them from the very beginning, and then it took me a while to find my voice.”
By the second semester, she found her footing, adjusting her approach to get her students engaged. The key, she says, has been to make herself approachable and her instruction personal. And, of course, add showy demonstrations. “These demonstrations often help students to connect these abstract concepts with real life.” she says.
Physics department head Grigory Rogachev says Erukhimova’s work has helped bring visibility to the department, with about 2. 5 million subscribers on its department’s YouTube page, which has translated to a boost in research funds and physics major applicants.
As a leader in a STEM field in which women are underrepresented, she’s become a role model for some. Afiya Dhanani attended Texas A&M University after seeing Erukhimova’s videos online. “Watching Dr. Tatiana do the experiments online, especially since she was a female leader. Was more inspiring for me to even go into physics.” Dhanani said in an interview with CBS Mornings. That’s all Erakhimova says she can hope for -making physics less forbidding and more exciting.

B.It makes more people to know about the department. |
C.It helps the department translate more research papers. |
D.It attracts more physics professors to join the department. |

7 . The Stanford marshmallow (棉花糖) test was originally conducted by psychologist Walter Mischel in the late 1960s. Children aged four to six at a nursery school were placed in a room. A single sugary treat, selected by the child, was placed on a table. Each child was told if they waited for 15 minutes before eating the treat, they would be given a second treat. Then they were left alone in the room. Follow-up studies with the children later in life showed a connection between an ability to wait long enough to obtain a second treat and various forms of success.
As adults we face a version of the marshmallow test every day. We’re not tempted by sugary treats, but by our computers, phones, and tablets — all the devices that connect us to the global delivery system for various types of information that do to us what marshmallows do to preschoolers.
We are tempted by sugary treats because our ancestors lived in a calorie-poor world, and our brains developed a response mechanism to these treats that reflected their value — a feeling of reward and satisfaction. But as we’ve reshaped the world around us, dramatically reducing the cost and effort involved in obtaining calories, we still have the same brains we had thousands of years ago, and this mismatch is at the heart of why so many of us struggle to resist tempting foods that we know we shouldn’t eat.
A similar process is at work in our response to information. Our formative environment as a species was information-poor, so our brains developed a mechanism that prized new information. But global connectivity has greatly changed our information environment. We are now ceaselessly bombarded (轰炸) with new information. Therefore, just as we need to be more thoughtful about our caloric consumption, we also need to be more thoughtful about our information consumption, resisting the temptation of the mental “junk food” in order to manage our time most effectively.

C.Delay eating for fifteen minutes. | D.Show respect for the researchers. |

10 . Critical thinking is the ability to think clearly and rationally, understanding the logical connection between ideas. Critical thinking has been the subject of much debate and thought since the time of early Greek philosophers such as Plato and Socrates and has continued to be a subject of discussion into the modern age, for example the ability to recognise fake news.
Critical thinking might be described as the ability to engage in reflective and independent thinking. In nature, critical thinking requires you to use your ability to reason. It is about being an active learner rather than a passive recipient of information.
Critical thinkers rigorously (严厉地) question ideas and assumptions rather than accepting them at face value. They will always seek to determine whether the ideas, arguments and findings represent the entire picture and are open to finding that they do not.
One of the most important aspects of critical thinking is to decide what you are aiming to achieve and then make a decision based on a range of possibilities.
Once you have clarified that aim for yourself you should use it as the starting point in all future situations requiring thought and, possibly, further decision making. Where needed, make your workmates, family or those around you aware of your intention to pursue this goal. You must then discipline yourself to keep on track until changing circumstances mean you have to revisit the start of the decision-making process.
However, there are things that get in the way of simple decision making. We all carry with us a range of likes and dislikes, learnt behaviours and personal preferences developed throughout our lives; they are the hallmarks of being human. A major contribution to ensuring we think critically is to be aware of these personal characteristics, preferences and biases (偏见) and make allowance for them when considering possible next steps.
The more clearly, we are aware of ourselves, our strengths and weaknesses, the more likely our critical thinking will be productive.
