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,” 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.”

1.Which of the following statements was the difficulty engineers met while making the robotic fly?

A.They did not have sufficient fund.

B.No ready-made components were available.

C.There was no model in their mind.

D.It was hard for them to assemble the components.

A.Wood’s design can replace animals in some experiments.

B.Animals are not allowed in biological experiments.

The idea that computers have some amount of “intelligence” is not new, says Ralph Haupter, the president of Microsoft Asia, pointing as far back as 1950 when computer pioneer Alan Turing asked whether machines can think. “So it has taken nearly 70 years for the right combination of factors to come together to move AI from concept to reality,” says Haupter.

It is predicted that the development of artificial intelligence will be the story of the coming generations, not just the coming year, but as 2019 gets underway, you’ll find AI will begin to touch your life in many ways according to some researchers.

“Personal assistant AIs will keep getting smarter. As our personal assistants learn more about our daily routines, I can imagine the day I need not to worry about preparing dinner. My AI knows what I like to eat, which days of the week I like to cook at home, and makes sure that when I get back from work all my groceries are waiting at my doorstep, ready for me to prepare that delicious meal I had been longing for.” ---Alecjandro Troccoli, senior research scientist, NVIDIA.

“Thanks to AI, the face will be the new credit card, the new driver’s license and the new barcode (条形码). Facial recognition is already completely transforming security with biometric capabilities being adopted, and seeing how technology and business are connected, like Amazon is with Whole Foods, I can see a near future where people will no longer need to stand in line at the store.” ---Georges Nahon, president, Orange Institute, a global research laboratory.

“2019 will be the year AI becomes real for medicine. By the end of the year we’re seeing solutions for population health, hospital operations and a broad set of clinical specialties quickly follow behind.” ---Mark Michalski, executive director, Massachusetts General Hospital.

1.What can we know about AI from the first two paragraphs?

A.People didn't expect AI to develop so rapidly.

B.The idea of AI just came up recently.

C.The concept of AI was put forward by Ralph Haupter.

D.It took more than 70 years to turn the concept into reality.

2.Who sees the future of AI doing housework instead of human being?

A.Alan Turing. B.Georges Nahon. C.Mark Michalski. D.Alejandro Troccoli.

3.What is Georges Nahon’s job?

A.Executive director of a hospital. B.President of a research laboratory.

C.Chairman of an energy corporation. D.Chief operating officer of a newspaper.

4.How is the passage developed?

A.By explaining cause and effect. B.By presenting research results.

C.By listing some predictions. D.By describing personal experiences.

The world is a colorful landscape of different languages, skin colors, and different cultures. It’s important to have a good understanding of different cultures in order to become a well-rounded person1.

One way is to read hooks written by authors from a particular culture. Reading works by authors who have a close relationship with a particular culture allows people to gain an authentic glimpse into the food, music, language, religion, and way of a life of a particular group of people.

2.

Another way to learn about different cultures is to try to learn a foreign language.3.A person can choose a language she has always wanted to learn and locate learning programs to help her master the language. Besides, one can enroll in a foreign language class in order to learn in a more formal setting. One can also try to visit areas of the city to establish social connection with native speakers of the language.

4.Seek out restaurants that feature authentic food from a variety of countries. Food is an important part of different cultures and allows people to gain deep understanding into a particular cultural group’s way of life.

Communicating with people from other countries through email or snail mail is another useful way to become familiar with different cultures.5.Various websites offer pen pal services, offering to connect individuals with pen friends around the world.

阅读下面短文，根据所给情节进行续写，使之构成一个完整的故事。

I’m originally from Orange County, California, where I had the pleasure and honor of serving as a Newport Beach ocean lifeguard for five seasons. Whenever I could, I got shifts working the Point. If you wanted to save lives, that's where you worked. The Point was known for its massive rip currents((激流)

So, late in a shift, I was working Tower 15. Two blocks to my right was another guard named Mike, working Tower 17. I'd known Mike for a number of years. Mike had a rough upbringing. You can tell just by looking at him. He has a number of really frightening tattoos (纹身)，and his bald head shows the scar he got from a broken beer bottle. Maybe he wasn't the friendliest guard on the beach. I admit, I didn't really get along with Mike. But everything he lacked in friendly appearance and social skills, he more than made up for in lifesaving ability.

He called me over the phone and said, “Hey, I got a couple kids. I gotta go give’ em a warning. Keep an eye on us. “

I said, “Sure, “ and hung up.

Anytime you get out of your tower, you're supposed to let somebody else know, in case a situation develops. And sure enough, as soon as he hung up the phone, a rip was snapped up under these two kids, and they're getting sucked out. Mike saw it before it's happening, and he's running full speed toward the ocean. I scanned the water. All I saw was two small. noses bobbing (上下浮动)in the water.

I dropped my binos(望远镜)and I called in and said,” “Double rescue 17-he's out. I'm going. “ Mike was already punching through the surf line. By now, the mother of the two kids realized what's happening. She's on her feet and screaming.

Paragraph 1:

Mike reached the kids-a brother and sister around eight or nine years old

_____________________________________________________________________________________________________________________________

Paragraph 2:

Then the mother glanced back and got her first good look at Mike, as well as his tattoos.
