21、When robots and humans interact in a shared environment, it is important for them to move in ways that prevent conflicts or accidents. To reduce the risk, roboticists have developed numerous techniques that monitor an environment, predict the future actions of humans, identify safe trajectories (轨迹) for a robot and control its movements accordingly.
Predicting human behavior and movements, however, can be incredibly challenging. Determining the future movements of a robot, on the other hand, could be far easier. If human users could anticipate the movements of robots and the effects these will have on the surrounding environment, they should then be able to easily adapt their actions in order to avoid accidents .
With this in mind, researchers at Kyushu University in Japan recently created a near-future perception system named Previewed Reality that allows human users to forecast future changes in their environment, which could then inform their decisions and guide their actions. This system compiles a data-set containing information about the position of objects, humans and robots within the same environment, to then produce simulations (模拟) of events that could take place in the near future. These simulations are presented to human users via Virtual Reality (VR) or Augmented Reality (AR) headsets.
To collect information about the position of different objects, robots, and humans in a shared environment, the researchers used a number of strategically placed sensors, including optical trackers that monitored the movements of objects or robots, and a RGB-D camera which mainly tracked human actions. The data gathered by the sensors was then fed to a motion planner and a dynamics simulator. Combining these two system components allowed the researchers to forecast changes in a given environment and synthesize (合成) images of events that are likely to occur in the near future, from the viewpoint of a specific human. Human users could then view these synthesized images simply through a VR headset or an AR display.
“This system provides human-friendly communication between a human and a robotic system.” the researchers explained. In their next studies, they plan to expand and simplify the perception system, for instance by creating a lighter and more affordable version that can be accessed on smart phones or other portable devices.
【1】Why did the researchers develop the system?

22、 High-pitched and yet distinct, the sound of a voice calling the name “Amy” is unmistakable. But this isn't a human cry—it's the voice of a killer whale called Wikie.
New research reveals that orcas are able to imitate human speech, saying words such as "hello", "one, two" and “bye bye”. The study also shows that the creatures are able to copy unfamiliar sounds produced by other orcas.
Writing in the journal Biological Sciences, researchers from institutions in Germany, UK, Spain and Chile, describe how they carried out the latest research with Wikie, a 14-year-old female orca living in an aquarium in France.
After first brushing up Wikie's grasp of the “copy” command, she was trained to imitate three familiar orca sounds made by her 3-year-old Moana. Wikie was then additionally exposed to five orca sounds she had never heard before, including noises sounding like a creaking door. Finally, Wikie was exposed to a human making three of the orca sounds, as well as six human sounds, including “hello”, “Amy”, “ah ha”, “one, two” and “bye bye”.
The team found that Wikie was often quickly able to copy the sounds, whether from an orca or a human, with all of the novel noises copied within 17 trials. What's more, two human sounds and all of the human-produced orca sounds were managed on the first attempt—although only one human sound "hello" was correctly produced more than 50% of the time on subsequent trials.
The creatures are already known for their ability to copy the movements of other orcas, with some reports suggesting they can also copy the sounds of bottlenose dolphins and sea lions after several trials.
Scientists say the discovery helps to cast light on how different groups of wild killer whales have ended up with distinct accents, adding weight to the idea that they are the result of imitation between orcas.
【1】What is the author's main purpose in writing the text?
A.To analyze orcas' speech abilities.
B.To highlight the conservation of the orca.
C.To inform us of orcas' ability to imitate sounds.

23、Many curious children have lately asked “How do glasses help you see?” Actually, they asked this at a very good time because more and more people are needing to wear glasses and we don’t really know why.
Our eyes let us see because light enters each eye, and the eye then creates a message that goes to the brain. The eyeball itself doesn’t actually “see”—the brain sees. The eyeballs just take pictures, like two little cameras. To see properly, each eyeball needs to send the light that enters it into a very exact spot inside the eyeball, called the retina(视网膜). If the light falls onto the incorrect place, everything goes wrong.
Many people won’t need glasses and can see just fine. This is because their eyeballs are focusing light properly onto the retina. However, some people have eyeballs that are too long. They are called “shortsighted”. For these people, things far away can look blurry(模糊的). Other people have eyeballs that are too short. They are called “farsighted” and things close to them can look blurry. Both shortsighted and farsighted people need glasses to help them see clearly. They work by helping the eyeball to focus light onto the correct place, the retina. Only then can we see clearly.
Maybe you have a grandma or grandpa who wears whenever they are reading books or using their mobile phone. When people get older, they usually become a little bit farsighted because a part of their eye called the lens becomes stiff and doesn’t work properly.
More and more young people in the world are needing to wear glasses. we’re not sure why, but some scientists think that children who spend too much time inside are more likely to need glasses. Children who need glasses but don’t wear them don’t do as well as in school. Once you need glasses, you usually need them forever—your eyes won’t go back to normal on their own.
I hope that one day we can find out why people’s eyeballs become too long or too short and then we can stop people needing to wear glasses in the first place. Then people will never lose or forget their glasses ever again!

24、Three Modern Services
When you're working a full-time job, studying or on the hunt for work, life can feel exhausting. The good news is that modern technology has made life easier in many ways, and with the following services, you'll find you have more time and energy for the things that matter.
Meal kit delivery services
Meal kit delivery services are one of the most underestimated innovations of the 21st century. How they work is simple. At the beginning you choose how many people need to eat in your household. Then, what your dietary requirements are, and any other preferences. Finally, you get to choose which meal kits will be delivered to your door.
No matter your diet, you can have an appropriate meal kit delivered. For example, check out these low carb meal delivery options. The kit comes complete with all the ingredients you need, already prepared. All you have to do is to follow the simple recipe to put them together and pop your meal in the oven.
With meal kit delivery, you don’t have to worry about cooking or spending money on takeout. Your trips to the grocery store will become easier and you'll waste less money and food.
Taskrabbit
One of the most frustrating aspects of having a place you call your own is that you have to take care of the maintenance(维修). Even if you are renting, there are certain tasks that your landlord will expect you to see to, whether a leaky tap or a problematic electrical appliance.
For this, Taskrabbit connects you with freelancers who are willing to take on just about any task for you. You can hire someone to take care of your leaky tap rather than spending your own time and energy doing it. You're giving someone work while enjoying your time off.
Postmates
Finally, one of the most convenient and useful services is, of course, Postmates. With Postmates, you can get just about anything delivered or deliver something yourself. You can get someone to do your groceries for you – simply make a list of what you need and choose whether the shopper should call you if something is out or if they can decide on replacements themselves.
You can also use it for takeout, to send or receive documents, and any other delivery needs you have.
We live in an age of convenience, and we should take advantage of it. Start using the above services and you'll see your stress levels drop.
