1 . If a pancake could dream, it might long for legs so it could jump off your breakfast plate in pursuit of a better, unchewed life. But legs aren’t necessary for something as flat as a pancake to jump around. A group of scientists have designed a pancake-shaped robot that can jump several times per second and higher than seven times its body height. The new robot named Hop, which swiftly jumps without feet, is an important contribution to the soft robotics.

Many ground robots move by rolling or walking. But it’s more efficient for robots to jump over obstacles (障碍物) than to go around them. Although jumping can offer some robots a competitive edge, engineering that ability has been a challenge for robotics researchers. Some soft robots that store energy can perform a single impressive jump very infrequently. Some lightweight soft robots that don’t store energy can jump frequently but can’t jump high or far enough to successfully cross an obstacle.

For inspiration, the researchers looked to gall midge larvae (瘿蚊幼虫) that miraculously throw themselves across distances 30 times as long as their loglike bodies. A gall midge larva bends its body and squeezes the liquid in its body to one end, making it rigid (僵硬的). The accumulation of liquid builds up pressure, and releasing the pressure sends it soaring (飙升). The robot’s body doesn’t resemble (像) that of a gall midge larva, but it jumps like one. Its body is made of two small plastic bags printed with electrodes; the front bag is filled with liquid and the back one is filled with the same volume of air. The robot uses electricity to drive the flow of liquid, which causes the body to bend and generate force with the ground, resulting in a jump. And the air bag imitates the function of an animal’s tail, helping the robot keep a stable position.

While the robot is currently restricted to Earth, it might be right at home exploring another planet. If this is true, the researchers robot might jump over dusty rocks and large holes on the moon or Mars, going where no pancake has gone before.

4 . Time and how we experience it have always puzzled us. Physicists have created fascinating theories, but their time is measured by a pendulum (钟摆) and is not psychological time, which leaps with little regard to the clock or calendar. As someone who understood the distinction observed, “When you sit with a nice girl for two hours it seems like a minute, but when you sit on a hot stove, a minute seems like two hours.”

Psychologists have long noticed that larger units of time, such as months and years, fly on swifter wings as we age. They also note that the more time is structured with schedules and appointments, the more rapidly it seems to pass. For example, a day at the office flies compared with a day at the beach.

Expectation and familiarity also make time seem to flow more rapidly. Almost all of us have had the experience of driving somewhere we’ve never been before. Surrounded by unfamiliar scenery, with no real idea of when we’ll arrive, we experience the trip as if lasting a long time. But the return trip, although exactly as long, seems to take far less time. The novelty of the outward journey has become routine.

When days become as similar as beads (小珠子) on a string, they mix together, and even months become a single day. To counter this, try to find ways to interrupt the structure of your day — to stop time, so to speak.

Learning something new is one of the ways to slow the passage of time. One of the reasons the days of our youth seems so full and long is that these are the days of learning and discovery. For many of us learning ends when we leave school, but this doesn’t have to be.

1. What can we know about time from Paragraph 1?

A．Physical time has little to do with the calendar.

B．Physical time is distinct from psychological time.

C．Time should not be measured by a pendulum.

D．Psychological time is quite more fascinating.

2. Which of the following will make you feel time flies faster?

A．A day spent exploring something unknown.

B．Staying with a person who you dislike.

C．A day packed with appointments to handle.

D．Driving to a new place for the first time.

3. What does “novelty” in Paragraph 3 probably mean?

A．Unfamiliarity.

B．Excitement.

C．Imagination.

D．Amusement.

4. What is the purpose of the passage?

A．To show the difference between physical and psychological time.

B．To explain why time flies and how to slow it down psychologically.

C．To describe how most of us experience time psychologically.

D．To give various explanations about fascinating time theories.

5 . The words “caring” and “empathetic” (共情的) aren’t ones normally associated with technology. Yearsley, an Australian enterpriser who is expert in artificial intelligence (AI), is trying to change that.

Yearsley is the founder of Akin, a robotics startup that currently uses a tablet-based system to help users manage the tasks related to home life, whether that’s planning meals or reminding you to pay your cell phone bill. Current home devices made by Google or Amazon or Apple use predictive AI to track patterns, strengthen behaviors and manipulate (操控) buying decisions, some of which, she assumes, are questionable or just unhealthy.

In contrast, the AI that she is developing will be designed to run the human home, encouraging healthful decisions such as taking a nightly walk, refilling the fridge and supporting social interactions like lunches or birthday celebrations with friends. “It’s the hardest AI I have ever built for it’s a complex system,” Yearsley says.

Yearsley began developing the Akin technology in 2017, when she realized the need to better manage the home is hugely ignored. Besides, she realized that women unequally bear the burden of household work. A United Nations’ report estimates that women do2.6 times the amount of unpaid care and domestic work that men do, or close to 30 hours per week in the U. S. alone.

While Yearsley pictures an army of robots someday helping with routine homemade tasks, the first display for Akin will take time and money. Akin has received some early seed money from a handful of investors, and was recently selected as a finalist for tech giant LG Nova’s Mission for the Future program, an annual challenge that seeks to identify businesses having potential to improve life and lead society into the future.

1. What might the Akin’s AI system suggest?

A．Consuming more drinks to enjoy yourself.	B．Staying up late working to make more money.
C．Spending more time staying with your family.	D．Purchasing products that may attract you.

2. What made Yearsley develop the Akin’s AI system?

A．The high cost of current home devices.	B．Akin’s becoming a finalist for a program.
C．Financial support from investors.	D．Heavy burden of housewives.

3. What can be used to describe the Akin’s AI system?

A．Questionable and unhealthy.	B．Unstable and insecure.
C．Thoughtful and innovative.	D．Mature and ideal.

4. What’s the purpose of the text?

A．To introduce a futuristic AI system.	B．To compare two companies’ AI systems.
C．To call on people to care about housewives.	D．To seek support for an AI expert.

7 . 阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。

Oliver was a small and introvert (内向的) boy who kept to himself. He was quiet and preferred indoor activities. Sitting in the corner of the class, he was very much a loner.

At the beginning of the semester, Oliver had a new classmate, Alan, who had just returned to England. Alan was assigned a seat next to Oliver. To his surprise, within weeks, he became good friends with Alan even though they were poles apart in personality. Alan was popular, outspoken and artistic. “Alan is all that I want to be,” Oliver thought to himself. He began listening to the music Alan listened to and having similar haircut. He even quit his drama club and started playing the online games that Alan played. He seemed to have been out of his loneliness.

It was not long before Oliver was introduced to Alan’s “cool” friends. He told himself that he would try all means to be part of the group. He would follow them to the football games and join the art club after school so he could spend more time hanging out with them. Oliver followed them around laughing when they told jokes, agreeing when they had opinions—most enthusiastically at the ones he disagreed with. He did not dare to differ in opinions as he would not want them to think badly of him. This continued for several months. At last, Oliver felt relieved that he had finally fitted in.

One day, Oliver overheard Alan and his cool friends talking. “Oliver is such a loser,” one boy commented in a playful tone. “He just follows you around trying to be you. He copies you; he does not have a personality of his own!” another boy exclaimed. Alan laughed, to make matters worse, he added, “That fellow wears me out. I wish he would leave me alone. He thinks we are best friends. A thorough fool!”
