In elementary school, Glenn Cameron was very aware of the challenges faced by his friend, Roger, who had lost a hand. Now he has built an artificial helper for him. The robotic hand is called “Dexi”. Each of its fingers can move independently. The strength and speed of the hand’s “muscles” can be controlled. He’s also created a digital version of this hand, which responds on a computer screen. Through a special headset, the system takes electrical signals from a human brain, sends them to a computer, and then the computer “tells” the hand what to do. For example, to make the hand close, you “see” a fist in your head. In fact, Cameron’s first robotic hand was 3D printed online. Realizing the hand was too limited, he decided to build his own. It was quite a challenge, but his new version was better. It was also cheap, compared to many other robotic hand projects. Cameron says designing and building the hand was hard, but he went on. Then came the one Roger is using. Cameron is working on a hand that can actually be used by a person who’s lost a hand at present. He says the new hand will be simpler, because there won’t be as much space. To make up for this, he’s adding a mini camera and trying to make the hand smarter. Cameron encourages young people who think they might want to do something demanding and similar, “You just begin working towards it. Take one little step at a time, purposeful and steadfast, sooner or later you’re going to get to the place you long for.” 【1】Which version of the artificial hand does Dexi belong to? A.The first. B.The second. C.The third. D.The fourth. 【2】How could a user of the digital version of Dexi control the robotic hand? A.By operating the computer. B.By thinking. C.By sending electrical signals to the hand. D.By speaking. 【3】Which saying do Cameron’s words convey? A.Well begun is half done. B.The longest journey begins with the first step. C.All things are difficult before they are easy. D.Nothing is impossible to a willing heart. 【4】What is the text mainly about? A.Cameron’s brain-controlled robotic hands. B.Cameron’s story of success. C.The latest designs of artificial intelligence hands. D.A robotic helper for the disabled. |

Frozen 2 sees the return of Elsa and Anna.This time,the Queen of Arendelle and her sister are in-tended to save the kingdom.The film,adding different topics and making breakthroughs,has won greater popularity. One big change since the first movie is what the leading women are wearing.Elsa and Anna branch out(出场)by wearing tights,not just skirts.It's rare to see Disney princesses in anything other than tradi-tionally woman style clothes.Director Jenifer Lee said the move represented contemporary attitudes. “Everyone sort of represents when the film was made and what the film's trying to show,”she said,“And that's right for these two women,who are carrying the weight of the kingdom.I love you can wear any-thing.” President of Walt Disney Animation Studios Clark Spencer thought it important to design what Elsa and Anna wear carefully.“This time,they don't have to flee their kingdom in the wrong dress,”said Spencer.“They're going on a big adventure.It's going to be very physical.It makes the audience aware there is more than one way to be a princess.” Pants are just the beginning.Another noticeable topic is the role of the environment,which helps them on their adventure when it feels respected and hurts them when threatened.What the filmmakers re-ally talked about is that the ecosystem is a big serious issue,according to Lee.“Climate change and nature out of balance might give Elsa the real purpose.Could that be why she has this power?That's something most of us talk about.But a core(核心的)theme of the movie is the idea of not trying to force the envi-ronment into your world,"she said.Every character is connected to this idea of respecting the strength and changes of the environment and taking care of the world around you. 【1】Why does the director change Elsa's and Anna's wear? A.To show the background of the movie. B.To increase the film's popularity. C.To express the idea of dressing freedom. D.To reflect the trend of the times. 【2】What might Clark Spencer think of the wear's change? A.It's a wrong choice. B.It makes sense. C.I's a risky decision.

An underwater robot named Icefin has gone to the bottom of Antarctica’s Thwaites Glacier (冰川) recently, which is one of Antarctica’s fastest melting glaciers. Even so, scientists learned unexpectedly that waters at the ground line, the region where the glacier meets the sea, are more than 2 degrees Celsius above the normal freezing temperature. The journey to collect the data wasn’t easy. Scientists dropped Icefin through a 700-meter-deep hole they had drilled through the glacier. “We’re proud of Icefin, since it represents a new way of looking at glaciers,” said Britney Schmidt, lead scientist for Icefin. “For really the first time, we can drive miles under the ice to measure and map processes we can’t otherwise reach. We’ve taken the first close-up look at a grounding zone. It’s our ‘walking on the moon’ moment.” The grounding zone is the region where the bottom of the glacier meets the sea water beneath it. The team spent the last two months in minus 30℃ weather at the glacier for the project. After going down the nearly half-mile hole through the glacier, Icefin swam more than a mile to the grounding zone. As it moved along, Icefin took measurements and recorded what it saw with an inside camera so that scientists could later map the area, as well as understand the temperatures and the changing landscape there. Thwaites Glacier, roughly the size of Florida, which prevents the ice behind it from freely flowing into the ocean, is melting at an increasingly fast rate. Its melting already accounts for about 4% of the global sea rise, Georgia Tech reported. The amount of ice flowing out of Thwaites into the sea has doubled in the past 30 years, greatly changing the landscape, temperatures and the ecosystem of Antarctica. “We know that warmer ocean waters are eroding many of West Antarctica’s glaciers, but we’re particularly concerned about Thwaites,” Keith Nicholls, an oceanographer with the British Antarctic Survey and the United Kingdom lead on the team, said in the Georgia Tech statement. “This new data will provide a new viewpoint of the processes taking place, so we can predict future change with more certainty.” 【1】What were scientists surprised to discover at the bottom of Thwaites Glacier? A.A melting glacier. B.Warm waters. C.The ground line. D.An underwater robot. 【2】What did Icefin do as it moved along underwater? A.It took photos. B.It mapped the area. C.It drilled holes. D.It measured sea water temperature. 【3】From paragraph 4, we can infer Thwaites Glacier ________. A.is extremely vital to Antarctica B.is a lot larger than Florida, USA C.is melting the fastest in Antarctica D.is to blame for the global sea rise entirely 【4】What does the underlined word “eroding” in the last paragraph mean? A.Accumulating. B.Shaping. C.Raising. D.Destroying. |

Why Not Build a DIY Ebike Buying an electric bicycle is a great way to get going quickly and enjoy the immediate satisfaction of getting around on an ebike. 【1】 There are some of the best reasons to go with a DIY ebike. Save money with a DIY ebike. When you buy an electric bicycle, you aren’t just paying for the ebike. 【2】 When you decide to convert (改装) your own standard bicycle into an electric bicycle, you just pay for the ebike parts themselves. Gain control when building your own ebike. When you choose your own parts, you have total control over the performance of your ebike. This applies more to choosing parts individually, but even buying a complete electric bicycle conversion kit (整套配件) is a great way to go. There are so many different kits out there for everyone. 【3】 A DIY ebike means a better bicycle. A dirty secret of the industry is that many ebike producers skimp on (克扣) the quality of the actual bicycle, so that they can try to bring the price down enough. 【4】 By converting a bicycle yourself, you’ve already saving a bunch of money. 【5】 The last and perhaps best reason for converting your own bicycle to electric drive is simply the sense of accomplishment. You get a great feeling every day when you ride on your ebike, knowing that you are doing a good thing for the environment and that you are also riding on something you built with your own two A.You can start with a simple electric bicycle. B.As a result, they can draw in more consumers. C.Be proud of building your own electric bicycle. D.Do your own electric bicycle conversion without any help. E.The kit you choose will largely depend on your own desires. F.However, converting your own bicycle into an ebike is better. G.You’re actually covering all of the cost to get that ebike out of store. |
