6、bots have fascinating jobs. These researchers tinker (修补)with machines in the lab and write computer software to control these devices. “Theyre the best toys out there,” says Howie Choset at Carnegie Mellon University in Pittsburgh. Choset is a roboticist, a person who designs, builds or programs ro

7、bots.When Choset was a kid, he was interested in anything that moved cars, trains, animals. He put motors on Tinkertoy cars to make them move. Later, in 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

8、 got to graduate school at the California Institute of Technology in Pasadena, Chosets labmates were working on something even cooler than remotely controlled cars： robotic snakes. Some robots can move only forward, backward, left and right. But snakes can twist (扭曲)in many directions and travel ove

9、r 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 Mellon, Choset and his colleagues there began developing their own snake robots. Chosets team programmed robots to perform the same movements as real sna

10、kes, such as sliding and inching forward. The robots aiso moved in ways that snakes usually dont, such as roiling. Chosets snake robots could crawl (爬行) 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. For some heart

11、surgeries, the doctor has to open a patients chest, cutting through the breastbone. Recovering from these surgeries can be very painful. What if the doctor could perform the operation by instead making a small hole in the body and sending in a thin robotic snake?Choset teamed up with Marco Zenati, a

12、 heart surgeon now at Harvard Medical School, to investigate the idea. Zenati practiced using the robot on a plastic model of the chest and then tested the robot in pigs.A company called Medrobotics in Boston is now adapting the technology for surgeries on people.Even after 15 years of working with

16、r ecological (生态的)system. An ecosystem is where living creatures expand within a given area. You can say that an ecosystem is the natural environment where biological organisms (生物)such as plants, animals and humans co-exist in this world. So naturally that includes you and me. Yes, we are all membe

17、rs of an ecosystem!2 There are different kinds of ecosystems depending on the type of surface or environment. Most are naturally made such as the ocean or lake and the desert or rainforest. Some are man-made or artificial to encourage co-habitation (共居)between living and non-living things in a monit

18、ored environment, such as a zoo or garden.3 Plants make up the biggest group of biological creatures within an ecosystem, and thats because they are the natural food producers for everyone. Plants raised in the earth need air and collect sunlight to help them grow. When they grow, the plants and Its

19、 fruits or flowers eventually become a source of food to animals, microorganisms (微生物)and even humans, of course. Food is then converted to energy for the rest of us to function, and this happens in a never-ending cycle until the living creatures die and break up back in the earth.4 Ecosystems are t

20、he basis of survival for all living things. We depend on plants and animals for food. In order for us to exist, we need to grow and care about other organisms. We also need to care for the non-living things within our environment like our air and water so we can continue living as a population. Sinc

21、e plants, animals and humans are all of various species (物种),we all play a role in maintaining the ecosystem.5 To preserve our ecosystems, we should stop using too much energy, which happens when we consume more than our share of resources. Humans should not disturb the natural habitat (栖息地)of plant

22、s and animals, and allow them to grow healthily for the cycle to continue. Too many people in a habitat can mean displacement (搬迁): imagine being thrown out of your home because there is no more space for everyone. Worse, overpopulation can also ruin the environment and cause destruction of existing

A new study finds that hungry people see food-related words

26、more clearly than people whove just eaten.Psychologists have known for decades that whats going on inside our heads affects our senses. For example, poorer children think coins are larger than they are, and hungry people think pictures of food are brighter. Remi Radel of University of Nice Sophia-An

27、tipolis, France, wanted to investigate how this happens. Does it happen right away as the brain receives signals from the eyes or a little later as the brains high-level thinking processes get involved?Radel recruited 42 students with a normal body mass (质量)index. On the day of his or her test, each

28、 student was told to arrive at the lab at noon after three or four hours of not eating. Then they were told there was a delay. Some were told to come back in 10 minutes; others were given an hour to get lunch first. So half the students were hungry when they did the experiment and the other half had

29、 just eaten.For the experiment, the participant looked at a computer screen. One by one, 80 words flashed on the screen for about 1/300th of a second each. They flashed at so small a size that the students could only consciously perceive. A quarter of the words were food- related. After each word, e

30、ach person was asked how bright the word was and asked to choose which of two words theyd seen - a food-related word like cake or a neutral (中性的)word like boat, Each word appeared too briefly for the participant to really read it.Hungry people saw the food-related words as brighter and were better a

31、t identifying food-related words. Because the word appeared too quickly for them to be reliably seen, this means that the difference is in perception, not in thinking processes，Radel says.“This is something great to me. Humans can really perceive what they need or what they strive (奋斗)for. From the experiment, I know that our brain can really be at the disposal (处理)of our motives (动机)and needs,” Radel says.31 “Poorer children” and “hungry people” are mentioned in Paragraph 2 to showA they have sharper senses than others.B they
