3 . 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)?

    1     They know that they have something special to contribute and they are determined to make their mark. This does not mean that they are too proud. On the contrary, they are self critical and push themselves hard because they know that they can achieve more.

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?     2     They take risks. They move out of their comfort zones. They take on difficult challenges. They push themselves to acquire new skills and to face new examinations of their abilities.     3     Where are you right now — inside your comfort zone or taking risks?

    4     Thinking and planning are great but it is action that leads to success. It is only by doing things and doing the right things that you change the world.

Let’s face it — your friends and family are really nice people but they are not challenging you to achieve more. Spend more time with high flyers and positive thinkers who understand ambition and achievement. Share some of your thoughts, dreams and challenges with them.     5    

A．High achievers go further.

B．This means that they run the risk of failure.

C．All successful people have strong self-belief.

D．They can take comfort in modest achievements.

E．You waste a lot of time every day on low value activities.

F．They will encourage you and give you the direct advice you need.

G．It is really very hard to make progress if you have no ambition for your life.

5 . 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.

1. What does Erukhimova’s online videos feature?

A．Rare materials.	B．Energetic presentation.
C．Plain demonstration.	D．Professional explanation.

2. Which saying explains Erukhimova’s initial failure to grab students’ attention 20 years ago?

A．All that glitters is not gold.

B．Sharp tools make good work.

C．First impressions are make or break.

D．A fall into the pit, a gain in your wit.

3. How does Erukhimova’s work contribute to the physics department?

A．It leads more students to change their majors.

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.

4. Which word best describes Erukhimova as a leader in a STEM field?

A．Inspirational.

B．Underestimated.

C．Cooperative.

D．Ambitious.

Tomato Changed My Life

Doing things-without being planned was never my strength.

As a 14-year-old, I would refuse to go for walks around the block with my friends if I was the least bit behind in my schoolwork.

Unlike most teenagers, I lived not in my room, but in an unused kitchen upstairs where I spread my books and papers on a large round table. I spent considerable time there, working continuously for hours, and my mother worried. She would try to lure (引诱) me away. “Come and watch the parade!” she would call from downstairs. “All neighbors are out there!” She thought of all kinds of tricks-the swimming pool, ice cream, stray cats and turtles-to remove me from my -studies, but nothing ever worked.

Later, in college, the pattern continued. The library and my college dorm replaced the unused kitchen at home. When spring came along friends would stop by my dorm or peer into my library room to persuade me to play Frisbee on the lawn. “No, I would almost always say.” I have too much to do.

My college study days were gone, but not my need and love for schedules. My friends and sisters tried to keep me away from my plans, but they were hardly ever successful.

This summer, though, while house sitting for my parents, I was persuaded to change my plans in the most unexpected way. The sight of tomatoes growing in my mother’s garden lured me out of my tightly scheduled world. They drew me with the power of a lover’s gaze. Hundreds of them were turning ripe and red by the minute, decorating the garden like decorations on a Christmas tree.

“If I have time, I’ll make tomato sauce (番茄酱).” I told myself. But my long week in the house by myself was already filled with things to do: writing, and finishing a project that I brought home from the office.

Then, watching the fascinating tomatoes continuously falling to the ground in ever-greater numbers, again I mentally argued about all the things I had planned and needed to do.

8 . As AI becomes popular, researchers have noticed its influence on the environment. Training an AI system requires huge computing power and electricity, and the resulting CO₂ emissions (排放) are one way AI affects the environment. But its environmental effect is more than its carbon (碳)footprint.

Jesse Dodge, a scientist at the Allen Institute, says, "The influence of Al systems is going to be from their applications, not the cost of training them." David Rolnick, a computer scientist at McGill University, compares AI to a hammer (锤子) “The main effect of a hammer is what is being hammered,” he says, "not what is in the hammer." Just like a hammer which can either destroy things or build a house, Al can hurt or help the environment.

In 2019, ExxonMobil, an oil company, said it would use Microsoft’s app Azure. With the Al technology, it would increase its production and create billions of dollars. This means Microsoft's AI is directly contributing to greenhouse gas emissions. This is not the only AI application that could be environmentally harmful. AI behind the ads that jump out on Instagram or Facebook pages pushes customers to spend more on products like clothes. This in turn causes more emissions through more production and delivery.

But on the other side of the coin, there are AI applications that can help deal with environmental problems, such as the destruction caused by hurricanes. One such application is xView2, a program started by a U. S. organization. It can recognize buildings damaged and people trapped in natural disasters, reducing danger and saving time for rescuers.

AI could be a valuable tool in the fight against climate change—if the Al industry can reduce its harmful climate effects. "Both AI and climate rules have roles to play." Rolnick says. When creating Al rules, he suggests considering its applications, emissions, and other production costs. Further, Dodge adds that those AI professionals should help set up some value systems to limit the technology's use.

1. Where does the effect of AI systems on the environment come from according to Dodge?

A．The popularity of AI.	B．The emissions of CO2.
C．The way of applying AI.	D．The cost of AI training.

2. How does the writer develop Paragraph 4?

A．By listing numbers.	B．By giving examples.
C．By comparing facts.	D．By explaining details.

3. What can we infer from the last paragraph?

A．Rules for AI can be helpful.	B．Al's advance should be limited.
C．Production costs will be lower.	D．AI plays a role in making rules.

4. What is the main idea of the passage?

A．AI applications are environmentally harmful.

B．AI affects the environment by CO2 emissions.

C．AI is effective in solving environmental problems.

D．AI's environmental effect goes beyond its emissions.
