题干

If it really is what’s on the inside that counts, then a lot of thin people might be in trouble.
Some doctors now think that the internal(内部的) fat surrounding important organs like the heart or liver could be as dangerous as the external fat which can be noticed more easily.
“Being thin doesn’t surely mean you are not fat,” said Dr Jimmy Bell at Imperial College. Since 1994, Bell and his team have scanned nearly 800 people with MRI machines to create “fat maps” showing where people store fat.
According to the result, people who keep their weight through diet rather than exercise are likely to have major deposits of internal fat, even if they are slim.
Even people with normal Body Mass Index scores can have surprising levels of fat deposits inside. Of the women, as many as 45 percent of those with normal BMI scores (20 to 25) actually had too high levels of internal fat. Among men, the percentage was nearly 60 percent.
According to Bell, people who are fat on the inside are actually on the edge of being fat. They eat too many fatty and sugary foods, but they are not eating enough to be fat. Scientists believe we naturally store fat around the belly first, but at some point, the body may start storing it elsewhere.
Doctors are unsure about the exact dangers of internal fat, but some think it has something to do with heart disease and diabetes(糖尿病). They want to prove that internal fat damages the body’s communication systems.
The good news is that internal fat can be easily burned off through exercise or even by improving your diet. “If you want to be healthy, there is noshortcut. Exercise has to be an important part of your lifestyle.” Bell said.

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.”
【小题1】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 not assemble the components

【小题2】It can be inferred from paragraphs 3 and 4 that the robotic fly __________.

A．consists of a flight device and a control system

B．can just fly in limited areas at the present time

C．can collect information from many sources

D．has been put into wide application

【小题3】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.

【小题4】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

When we are in a bad mood or ill at ease, as long as we listen to a beautiful song, we will feel better and relaxed. A musical _____ always makes us comfortable. By listening to music, we also can understand the philosophies which _____ the music.

Music not only can change our moods, but also can _____ some kinds of diseases, such as insomnia (失眠). Music treatment has been _____ in many countries recently. It has been _____ that music can make people relaxed, more _____ and have a better sleep. Some music even can promote us to _____ a certain number of natural chemicals from our bodies. Besides, music also has a good effect on strengthening people’s memory. In a university, 60 girl students accepted a (n) _____ , It showed that the girls who received musical training in their childhoods could _____ 17% more reading materials than those who didn’t. Some experts also ______ that musicians’ left brains are bigger in size than ordinary people’s. As we know, our memory is ______ by the left brain. That might be the reason why those who receive musical training have a better memory. ______ , the patients whose speaking is damaged may recover ______ by listening to or appreciating some music.
