8、n high school, he built mobile robots similar to small cars.Hoping to continue working on robots, he studied computer science in college. But when he got to graduate school at the California Institute of Technology in Pasadena, Chosets labmates were working on something even cooler than remotely con

9、trolled cars: robotic snakes. Some robots can move only forward, backward, left and right. But snakes can twist (扭曲) in many directions and travel over a lot of different types of terrain (地形). Snakes are far more interesting than the cars, Choset concluded.After he started working at Carnegie Mello

10、n, Choset and his colleagues there began developing their own snake robots. Chosets team programmed robots to perform the same movements as real snakes, such as sliding and inching forward. The robots also moved in ways that snakes usually dont, such as rolling. Chosets snake robots could crawl (爬行)

11、 through the grass, swim in a pond and even climb a flagpole.But Choset wondered if his snakes might be useful for medicine as well.

17、中为每个句子确定一个最佳选项。Black Holes1. Black holes can be best described as a sort of vacuum, sucking up everything in space. Scientists have discovered that black holes come from an explosion of huge stars. Stars that are near death can no longer burn due to loss of fuel, and because its temperature can no l

18、onger control the gravitational (重力的) force, hydrogen ends up putting pressure onto the stars surface until it suddenly explodes then collapses.2. Black holes come from stars that are made of hydrogen, other gases and a few metals. When these explode it can turn into a stellar-mass (恒星质量) black hole

19、, which can only occur if the star is large enough (should be bigger than the sun) for the explosion to break it into pieces, and the gravity starts to compact every piece into the tiniest particle. Try to see and compare: if a star thats ten times the size of the sun ends up being a black hole that

20、s no longer than 70 kilometers, then the Earth would become a black hole thats only a fraction of an inch!3. Objects that get sucked in a black hole will always remain there, never to break free. But remember that black holes can only gobble up (吞噬) objects within a specific distance to it. Its poss

21、ible for a large star near the sun to become a black hole, but the sun will continue to stay in place. Orbits do not change because the newly formed black hole contains exactly the same amount of mass as when it was a star, only this time its mass is totally contracted that it can end up as no bigge

22、r than a state.4. So far, astronomers have figured out that black holes exist because of Albert Einsteins theory of relativity. In the end, through numerous studies, they have discovered that black holes truly exist. Since black holes trap light and do not give off light, it is nearly impossible to

23、detect black holes via a telescope. But astronomers continue to study galaxies, space and the solar system to understand how black holes might evolve. It is possible that black holes can exist for millions of years, and later contribute to a bigger process in galaxies, which can eventually lead to c
