    About one million adults in the USA need someone to help them eat. Researchers at the University of Washington are working on a robotic system that can help make it easier. After identifying different food on a plate, the robot can decide how to use a fork to pick up and deliver the desired bite to a person s mouth.

    "Being dependent on a caregiver to feed every bite every day takes away a person's sense of independence," said the researcher. "Our goal with this project is to give people a bit more control over their lives the idea was to develop a feeding system that would be attached to wheelchairs and feed people whatever they wanted to eat.

    "When we started the project, we realized there are so many ways that people can eat a piece of food depending on its size, shape or consistency(坚实度)," said the researcher, "So we set up an experiment to see how humans eat common foods. "

    The researchers arranged plates with about a dozen different kinds of food, ranging in consistency from hard carrots to soft bananas. Then the team gave volunteers a fork and asked them to pick up different pieces of food and feed them to a model. The fork contained a sensor to measure how much force people used when they picked up food.

    To design a feeding strategy that changes based on the food item, the researchers combined two different algorithms (算法). First they used an object-detection algorithm called Retina Net, which scans the plate, identifies the types of food on it and places a frame around each item. Then they developed SPNet, an algorithm that examines the type of food in a specific frame and tells the robot the best way to pick up the food.

    The team is currently working with the Taskar Center for Accessible Technology to get advice from caregivers and patients on how to improve the system to meet people's need.

(1)、Why do the researchers work on the robotic system?
A、To help old people live a normal life. B、To help people improve their health. C、To release people from heavy housework. D、To make some people more independent.
(2)、How does the robotic system work?
A、By picking up some soft food. B、By picking out food on the wheelchair. C、By working with some nurses. D、By observing and delivering food.
(3)、What can be inferred about the robotic system?
A、It needs further research. B、It has come onto the market. C、It is suitable for any disabled person. D、It has won people's great concern.
(4)、What may be the best title for the text?
A、The process of inventing a robotic system. B、A new way to help those who don't like eating. C、Robotic feeders for humans are coming into being. D、Caregivers are going to lose their jobs in the future.

    If you have a chance to go to Finland, you will probably be surprised to find how “foolish” the Finnish people are.

    Take the taxi drivers for example. Taxis in Finland are mostly high-class Benz with a fare of two US dollars a kilometer. You can go anywhere in one, tell the driver to drop you at any place, say that you have some business to attend to, and then walk off without paying your fare. The driver would not show the least sign of anxiety.

    The dining rooms in all big hotels not only serve their guests, but also serve outside diners. Hotel guests have their meals free, so they naturally go to the free dining rooms to have their meals. The most they would do to show their good faith is to wave their registration card to the waiter. With such a loose check, you can easily use any old registration card to take a couple of friends to dine free of charge.

    The Finnish workers are paid by the hour. They are very much on their own as soon as they have agreed with the boss on the rate(价钱). From then on, they just say how many hours they have worked and they will be paid accordingly(相应地).

    With so many loopholes(漏洞) in everyday life, surely Finland must be a heaven to those who love to take “petty advantages”. But the strange thing is, all the taxi passengers would always come back to pay their fare after they have attended to their business; not a single outsider has ever been found in the free hotel dining rooms. And workers always give an honest account of the exact hours they put in. As the Finns always act on good faith in everything they do, living in such a society has turned everyone into a real “gentleman”.

    In a society of such high moral practice, what need is there for people to be on guard against others?

    It is interesting to see that the force of only 6 or 7 people pushing in the same direction can cause up to 1,000 pounds of force-enough to break brick walls. During a deadly stampede(逃奔), people can even die standing up. People die when pressure is put to their bodies in a front to back direction, causing them not to be able to breathe.

    If you are in a crowd, the first and most important thing is to make yourself familiar with your surroundings and find different exits. No matter where you are, make sure you always know how to get out.

    Make yourself aware of the type of the ground you are standing on, and know that in a crowd of moving people wet ground can cause you to fall.

    When in danger, a few seconds can make a difference, giving you the possibility of making use of your escaping route. Always stay closer to the escape route. If you find yourself in the middle of a moving crowd, do not fight against the pressure, do not stand still or sit down, because you can easily get trampled(踩踏). Instead, move in the same direction of the crowd; make use of any space that may open up to move sideways to the crowd movement where the flow is weaker.

    Keep your hands up by your chest, like a boxer-it gives you movement and protects your chest. If you fall, get up quickly. If you can't get up because you are injured, get someone to pull you up. If you have kids, lift them up.

    If you fall and cannot get up, keep moving in the same direction of the crowd, or if that is not possible, then cover your head with your arms; do not lie on your stomach or back.

    A new discovery may change how scientists think about prehistoric humans. Human history is more of a war movie than a romantic comedy, at least as far as other animals are concerned; we may be causing one of the planet's great extinction events at the moment. But a recent discovery means humans might not be as destructive as we thought.

    Large animals have a history of disappearing when humans move to their areas. Scientists have long believed that humans simply hunted big animals because people are really good at hunting. For example, scientists thought humans arrived in Madagascar around 4,000 years ago, but only two thousand years later, giant lemurs, giant tortoises and elephant birds disappeared from the island. Many scientists thought humans had something to do with that rapid drop in biodiversity(生物多样性).

    At least, that's what scientists thought until a group of researchers dug up a lot of bones in Madagascar recently. These bones belonged to the elephant bird, a kind of extinct bird that weighed up to 1,000 pounds. The huge bones were covered in cuts that clearly came from a human hunter. The researchers found that the humans had killed the birds 10,000 years ago...Thousands of years before scientists believed humans had come to the island.

    "Our research provides evidence of human activity in Madagascar more than 6,000 years earlier than suspected, which shows that a different extinction theory is required to understand the huge biodiversity loss that has happened on the island." explained James Hansford, one of the researchers. "Humans seem to have coexisted with elephant birds and other now-extinct species for over 8,000 years, clearly with limited negative influence on biodiversity for most of this period."

    If humans lived among large animals for thousands of years without wiping them out, then maybe our species can't wipe other species out. Rather, extinction is more of a habit we've learned. Perhaps we can unlearn it too.

    Sure, it's good to get along with your teacher because it makes the time you spend in the classroom more pleasant.

    And yes, it's good to get along with your teacher because, in general, it's smart to learn how to understand the different types of people you'll meet throughout your life

    "But really, there's one super-important reason why you should get along with your teacher. When you do, learning bursts right open," says Evelyn Vuko, a longtime teacher who writes an education column (专栏) called "Teacher Says" for the Washington Post newspaper.

    In fact, kids who get along with their teachers not only learn more, but they're more comfortable asking questions and getting extra help. This makes it easier to understand new material and do your best on tests. When you have this kind of relationship with a teacher, he or she can be someone to turn to with problems, such as problems with learning or school life like bullying.

    As a kid in a primary or middle school, you're at a wonderful stage in your life. You're like a sponge(海绵), able to absorb lots of new and exciting information. On top of that, you're able to think about all this information in new ways. Your teacher knows that, and, in most cases, is very excited to be the person who's giving you all that material and helping you make it. Remember, teachers are people, too, and they feel great if you're open to what they're teaching you. That's why they wanted to be teachers in the first place—to teach!

    Some kids may be able to learn in any situation, whether they like the teacher or not. But most kids are sensitive to the way they get along with the teacher, and if things aren't going well, they won't learn as well and won't enjoy being in class.
