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 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."
The difficulty the team of engineers met with while making the robotic fly was that ________.
A. they had no model in their mind B. they did not have sufficient time
C. they had no ready-made components D. they could no assemble the components
It can be inferred from paragraphs 3 and 4 that the robotic fly ________.
A. consists of a flight device and a control system
B. has been put into wide application
C. can collect information from many sources
D. can just fly in limited areas at the present time
Which of the following can be learned from the passage
A. The robotic flyer is designed to learn about insects.
B. Animals are not allowed in biological experiments.
C. There used to be few ways to study how insects fly.
D. Wood's design can replace animals in some experiments.
Which of the following might be the best title of the passage
A. Father of Robotic Fly B. Inspiration from Engineering Science
C. Robotic Fly Imitates Real Life Insect D. Harvard Breaks Through in Insect Study
二、阅读七选五(本大题共5小题,共10.0分)
Imagine going to the doctor to get treatment for a terrible fever. ___5___ The robot detects the cause of your fever, travels to the appropriate system and provides medication directly to the infected area.
___6____ They are called nanorobots and engineering teams around the world are working to design robots that will eventually be used to treat everything from fever to cancer.
In recent years researchers have been building nanorobots out of a familiar material—the same stuff that makes human life possible. ___7_____ DNA is literally all around and in you—you just can't see it. If you were to look inside almost any cell inside any living creature, you would find DNA.
This might sound surprising—especially since these nanorobots don't need batteries or any power source. Instead, they work by using the natural structure of DNA. The nanorobots "crawl" on DNA. Sometimes researchers refer to these things as DNA "spiders". ____8_______ A nanorobot could, perhaps, destroy just a cancerous cell, for example, but leave healthy cells alone.
_____9_____ But the future is bright for DNA-built nanorobots. One day, perhaps DNA-made machine will swim around in the human body, delivering medicine to diseased cells or helping doctors diagnose problems. Or maybe they'll help build the smallest computers the world has ever seen.
A.These nanorobots are made of DNA.
B.Nanorobots made from DNA aren't useful yet.
C.This description will give you a simple picture of the legs of a DNA nanorobot.
D.In other words, the DNA nanorobot destroys the track as it goes.
E.Being able to make such a tiny thing move in a certain way might be useful for health.
F.Instead of giving you a pill or a shot, the doctor puts a tiny robot into your bloodstream.
G.In fact, we're not that far off from seeing devices like this actually used in medical procedures.

We asked Professor John Williams, a futurologist, for his expert predictions on life in the next few decades.
"Unfortunately, it looks quite likely that the climate may (10) significantly (显著地), with hotter summers, colder winters and more flooding. At the same time, fuel for heating or air conditioning will probably become much more expensive. For these reasons, our houses will certainly have to become much better (11) . People are already building so-called 'passive houses', which have little or no central heating at all, (12) the body heat of the people who live there.
"Homes probably won't be as big, and so we will need more adaptable (可改变的) furniture, such as sofa beds, and when we are not (13) our furniture we will be able to fold it away into wall cabinets (壁橱). Houses could have moveable walls so that the same space can be (14) in different ways."
"New technology will make us more self-sufficient (自给自足的). Kitchens may have fish tanks which, as well as providing fish to eat, also (15) fresh vegetables. The plants will (16) oxygen for the fish. These tanks will be powered by household waste and create (17) , which can then be used to run the family car— (18) we might not all have cars!"
"Water will be more expensive and the home of the future will probably be designed to use much (19) water. Washing machines and dishwashers might use sound waves to shake (20) off. We may even take showers using sound waves. What water we do use will be recycled and used again round the house and private swimming pools will become a thing of the (21) ."
"We will also (22) have more robots in our houses, though they won't look like the ones in films. There will probably be small robots (23) to clean the fridge or open the curtains. (24) fridges will tell us when food is about to go out of date and even suggest recipes, and we will be able to communicate with our homes by mobile phone wherever we are."
