A team of engineers at Harvard University has been inspired by Nature to create the first robotic fly. The mechanical fly has become a platform for a series of new high-tech integrated systems. Designed to do what a fly does naturally, the tiny machine is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.

“It’s extremely important for us to think about this as a whole system and not just the sum of a bunch of individual components (元件),” said Robert Wood, the Harvard engineering professor who has been working on the robotic fly project for over a decade. A few years ago, his team got the go-ahead to start piecing together the components. “The added difficulty with a project like this is that actually none of those components are off the shelf and so we have to develop them all on our own,” he said.

They engineered a series of systems to start and drive the robotic fly. “The seemingly simple system which just moves the wings has a number of interdependencies on the individual components, each of which individually has to perform well, but then has to be matched well to everything it’s connected to,” said Wood. The flight device was built into a set of power, computation, sensing and control systems. Wood says the success of the project proves that the flying robot with these tiny components can be built and manufactured.

While this first robotic flyer is linked to a small, off-board power source, the goal is eventually to equip it with a built-in power source, so that it might someday perform data-gathering work at rescue sites, in farmers’ fields or on the battlefield. “Basically it should be able to take off, land and fly around,” he said.

Wood says the design offers a new way to study flight mechanics and control at insect-scale. Yet, the power, sensing and computation technologies on board could have much broader applications. “You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animals, but using these robots instead,” he said. “So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day to day basis.”

A few years before, Jack and I had a quarrel over score in a football match. From then on, we didn’t speak to each other any longer.

One day, when I was standing by a tree read, a ball flew to me and I kicked it back with looking at the player, but while I put up my head, I found it was Jack. Seen him, I was feeling very embarrassed. However, he was smiled to me, so I smiled either. Then we began to make up.

This way the walls between us were torn down with a smile but we become good friends again.

Most of us seem to reach our peak of alertness (警觉) around noon. Soon after that, alertness declines, and sleepiness may set in by mid-afternoon.

Your short-term memory is best during the morning—in fact, about 15 percent more efficient than at any other time of day. So, students, take notice: when you are faced with a morning exam, it really does pay to review your notes right before the test is given.

However, long-term memory is different. Afternoon is the best time for learning materials that you want to recall days, weeks or months later. Politicians, business executives or others who must learn speeches would be smart to do their memorizing during that time of day. You should try to do most of your studying in the afternoon, rather than late at night. Many students believe they memorize better while burning the midnight oil because their short-term recall is better during the early hours of the morning than in the afternoon. But short-term memory won’t help them much several days later, when they face the exam.

By contrast, we tend to do best on tasks related to the process of knowing, understanding, and learning numbers during the morning hours.

What about sports? During afternoon and early evening, you’re able to react the quickest to an outside stimulus—like a baseball speeding toward you. Studies have also shown that late in the day, when your body temperature is peaking, you will consider PE easier and less tiring—whether it actually is or not. That means you are more likely to work harder during a late afternoon or early evening workout, and therefore benefit more from it.

In fact, all of your senses—taste, sight, hearing, touch and smell—may be at their keenest during late afternoon and early evening. That could be why dinner usually tastes better to us than breakfast.

While all of us follow the same general pattern of ups and downs, the exact timing varies from person to person. It all depends on how your “biological” day is structured. Each of us can increase our knowledge about our individual rhythms. Learn how to listen to the inner beats of your body; let them set the pace of your day. You will live a healthier and happier life.

1.What does the underlined “it really does pay” mean?

A．It will cost a lot. B．It requires price.

C．It is very painful. D．It is worthwhile.

2.If there is an English exam two weeks later, you should go over English ____________ for days before that.

A．in the afternoon B．in the late evening

C．in the early morning D．right before the exam

3.From the passage, it can be inferred that ______________.

A．we eat more food at noon

B．we feel most tired if we exercise in the evening

C．it is a good choice to study math in the morning

D．we feel most sleepy before noon

4.Which would be the best title for the passage?

A．What’s Your Best Time of the Day for Different Tasks

B．How to Live a Healthier and Happier Life

C．How to Study Efficiently

D．How to Keep Your Best State of Learning
