    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.
(2)、What can be inferred from paragraphs 3 and 4?
A、The robotic fly has been put into wide application. B、The robotic fly consists of a flight device and a control system. C、Information from many sources can be collected by the robotic fly. D、The robotic fly can just fly in limited areas at present.
(3)、Which of the following can be learned from the passage?
A、Wood's design can replace animals in some experiments. B、Animals are not allowed in biological experiments. C、The robotic flyer is designed to learn about insects. D、There used to be few ways to study how insects fly.
(4)、Which of the following might be the best title of the passage?
A、The Development of Robotic Fly B、Robotic Fly Promotes Engineering Science C、Harvard's Efforts in Making Robotic Fly D、Robotic Fly Imitates Real Life Insect

    Many people think of guys as being carefree when it comes to their appearance . But in fact , a lot of guys spend plenty of time in front of the mirror . They care just as much as girls do about their body image.

    Body image is a person's opinions and feelings about his or her own body and physical appearance. {#blank#}1{#/blank#} You appreciate your body for its capabilities and accept its imperfections.

{#blank#}2{#/blank#} Here are some ideas:

    Recognize your strengths. Different body types are good for different things. What does your body do well? Maybe your speed, strength, or coordination makes you better than others at a certain sport. That may be basketball, table tennis, mountain biking , dancing , or even running . Or perhaps you have non-sports skills, like drawing, painting , singing , playing a musical instrument , writing , or acting . {#blank#}3{#/blank#}

    Exercise regularly. Exercise can help you look good and feel good about yourself. Good physiques(体形)don't just happen . {#blank#}4{#/blank#} A healthy habit can be as simple as exercising 20 minutes to 1 hour three days a week . Working out can also lift your spirits .

    Respect your body ! Practicing good habits – regular showering ; taking care of your teeth , hair , and skin ; wearing clean clothes , and so on – can help you build a positive body image .

    {#blank#}5{#/blank#} Your body is just one part of who you are . Your talent for comedy , a quick wit(智慧), and all the other things make you unique . So try not to let small imperfections take over.

A. Be yourself .

B. Just explore talents that you feel good about .

C. So , what can you do to develop a positive body image ?

D. They take hard work , regular workouts , and a healthy diet .

E. Use this as an opportunity to discover what you're good at .

F. The good news is that self-image and body image can be changed .

G. Having a positive body image means feeling satisfied with the way you look.

    No one enjoys hearing the sound of someone else chewing their food. Most of the time, though, it's not that big a deal but a minor annoyance.

    But for a small group of people with misophonia (恐音症), the sound can be painful, causing extreme anger and deep discomfort. The most ordinary sounds of chewing and breathing can drive them crazy. Past attempts to explain the causes of misophonia have suggested everything from compulsive disorder to an easily-annoyed personality—but according to a study published yesterday in the journal CurrentBiology, the true criminal is the structure of the brain.

    For the study, a team of researchers led by Newcastle University neuroscientist Sukhbinder Kumar recruited (招募) 42 volunteers, of whom around half had extreme misophonia and the other half served as the control group, and played them several different noises: some ordinary; some harsh, like the sound of a person screaming; and some that were ordinary for the control group but known to be annoying for misophonics, people with misophonia, like the sound of breathing. As the participants listened, the researchers monitored them for signs of anxiety, both physical symptoms and behavioral expressions, and observed their brain activity using FMRI scans.

    The only significant difference in reaction between the two groups happened, during the misophonia-specific sounds, when those with the condition showed physical changes that suggested they were entering fight-or-flight mode.

    Misophonics had increased activity in the AIC, an area known to play a central role in the system that determines which things we should pay attention to. When the trigger sounds were played, there was not only more activity in this region but also abnormally high levels of connection to other regions.

    Misophonia, in other words, may be a result of misplaced attention the brain of a misophonic focuses on things that other people normally tune out (不予理会). On a related note, on behalf of misophonics and manners-minded moms everywhere: Please, chew with your mouth closed.
