2 . When drones (无人机) first became widely available around 15 years ago, it wasn’t uncommon to find tech people painting dramatic pictures of how they were soon going to change the world. However, if you look up into the largely empty sky, you can see that hasn’t happened yet.
Sure, drones are useful for taking aerial (空中的) photos, but we’re a long way away from aerial superhighways, packed with autonomous drones carrying parcels at speeds that are near-impossible on the ground.
In 2016, Amazon announced it had completed its first ever aerial delivery. In a video, we saw an Amazon “Prime Air” drone pick up a parcel and fly it across the countryside landing in the buyer’s garden, dropping the parcel, and then returning to its home base. But Amazon still hasn’t completed its second drone delivery. In fact, it has reportedly downsized the drone program.
So, will drone delivery ever be a thing? There are some indications of a possible drone delivery future not in Britain, but in Africa. Because also since 2016, rural hospitals in Rwanda have been receiving regular shipments of medical supplies by drone thanks to a company called Zipline. It surely has saved lives, thanks to the speed at which blood can be delivered in a country with a poorly developed road network. So could we ever expect such a system here?
Unfortunately, there’s a big difference between rural Africa and thickly populated Britain. British homes don’t have large gardens where to land and nobody wants loud large drones constantly landing around the neighbourhood. Another reality is that British cities may still have security and safety concerns about routinely having drones carrying stuff over our heads.
That’s why I wonder if the real drone future could be crawling (爬) along the ground. For a few years, “autonomous delivery robots” with wheels have been walking on the pavements. So perhaps we’re not so far away from a drone delivery future, but the reality might be a little bit more down to earth.

I’m still a ordinary Senior 3 student, struggling to balance school work and my personal life under great pressures. I’m always wondering how my life will be like when I’m 30 years old. Encouraging by a famous professional interpreter, I have always dreamed becoming an interpreter. I suppose that after 14 years of hard work, you will definitely achieve this dream. I know that taking on this job meant taking on a great deal of responsibility. Serving as a bridge of communication, and I’ll work to improve the relationships between countries and making China's voice heard by the world. I’ll do my share to contribute to a peace world.
4 . If you could travel in time, where would you go? Perhaps you would watch an original performance of a Shakespeare’s play in Elizabethan England? What about hanging out with Laozi in the Spring and Autumn Period? Or maybe you’d voyage far ahead of the present day to see what the future holds.
The possibility of time travel is indeed appealing. Stories exploring the subject have been around for hundreds of years. Perhaps the best known example is the science fiction novel The Time Machine, which was written by H. G. Wells and published in 1895 for the first time. It was adapted into at least two feature films of the same name, as well as two television versions, and a large number of comic book adaptations. It is generally credited with the popularization of the concept of time travel using a vehicle that allows an operator to travel purposefully and selectively. The term “time machine”, coined by Wells, is now universally used to refer to a vehicle transporting people into the far future.
But could time travel actually be possible? Some scientists say yes, in theory. They propose using cracks in time and space called “wormholes”, which could be used as shortcuts to other periods. Einstein’s theory of relativity allows time travel in extreme circumstances. And British physicist Stephen Hawking said you could travel into the future with a really fast spaceship—going at nearly the speed of light. Though building such a spaceship would of course be no simple task.
Even if you could travel into the past, there is something called the “grandfather paradox”. It asks what would happen if a time traveller were to go back in time and have his own grandfather killed for some reason, and therefore prevent himself from being born. If the time traveller wasn’t born, how would he travel back in time?
And would you really like to visit the future? In H. G. Wells’ book, the main character travels into distant time where he arrives at a beach and is attacked by giant crabs. He then voyages 30 million years into the future where the only living thing is a black object with tentacles (触角). If that’s what’s in store, maybe we are better just living in the present day after all.

When I was in junior high, I was study machine. But I was will to do so because I understood how vital study was. I gave out all my rest time including summer and winter vacation with all weekends, that was highly odd and extreme in other’s eyes. Those years our motherland was still advanced, giving the cruel fact that Chinese GDP only surpassed that those of Japan. I studied so hard like a maniac China’s first premier Zhou Enlai did.

I have a dream that one day I could be the pianist. I dream of play a sweet piece of music for those who need music, bringing happiness for other. I love music and I love the feel of playing music in front of the audience. Of all the musical sounds, the beautiful but powerful sound a piano makes impresses me much. It’s clear I have a long way to go before I realize my dream. Therefore, I will practice for two hours every day if time permitted and learn as many songs as I can. I will put down my heart into my dream and never give up. I am confidence that one day my dream will come true.
8 . Brain aneurysms (脑动脉瘤) affect about one in every 50 Americans and can lead to serious medical emergencies, including stroke, brain damage and death if they burst. Existing treatment options are limited and often invasive(扩散), and surgical outcomes can vary widely from person to person.
Researchers at Lawrence Livermore National Laboratory (LLNL) have become the first team to produce a living, bioprinted aneurysm outside of the human body, perform a medical procedure on it and observe it respond and heal as it would in an actual human brain.
“While there are a lot of promising treatment options, some still have a long way to go,” said Moya, the project’s principal investigator. One common treatment is “clipping”-attaching a metal clip to the base of the aneurysm to redirect blood flow away and keep it from bursting. The procedure is highly invasive, requiring surgeons to open up the skull and expose the brain. A more common and less invasive treatment is the metal coiling (缠绕) approach. The downside to “coiling” is that success is highly dependent on a variety of factors, including the geometry of the patient’s blood vessels, which differ from one person to the next, researchers said.
Animal models aren't necessarily the best way to try out these options, as they lack direct observation of treatment effects and have uncontrollable aneurysm geometries. Unlike animal models, LLNL’s platform allows scientists to directly measure the liquid.
To take some of the guesswork out of aneurysm treatments, Hynes, the original principal investigator, realized researchers would need a way to validate more predictive 3D models that take patient geometry into account by bioprinting with human cells.
By combining the 3D-printed platform with computational models, researchers said they've developed a potential tool for surgeons to pre-select the best coil types, and perform “testruns” of procedures before attempting them on the human patient “What’s exciting is that this platform copies the actual blood vessels and also is strong enough to handle a coiling procedure. This makes it ideal to be used as a training platform for surgeons.” Moya said.
In addition to a testbed for surgical training, researchers said the platform has potential for improving the understanding of basic biology and the post-surgery healing response. While early results are promising, the researchers cautioned there's a long way to go before the platform sees application in the clinical environment.

9 . In the past few decades, great progress has been made in the field of space exploration, which has enabled mankind to have a deeper understanding of the Solar System, our place in it and in the universe. “We sent probes(探测器) to every planet in the Solar System. This is by far the best one,” said Clayton, vice president of Blue Origin. “Let's focus right now on protecting the Earth environment, and then we'll go from there. Space science and technology should be people-centric and application-centric, and focus on improving human life. We need to have a strong footing on the Earth, learn to solve the day-to-day problems of the society.”
“Space technology can help achieve the 17 sustainable development goals to be achieved by 2030 set by the United Nations. Satellite monitoring can really help with agriculture. ” said Victoria, CEO of a company working on sustainable development, “Through Global Navigation Satellite System, animals' movement information recorded on self-recharging devices can be transmitted to the company server. Farmers can be alerted in real time if anomalies(异常现象)are detected. We can use it to ensure the traceability of the entire meat chain. As a result, it enables consumers to know that the beef they are eating does not come from protected areas or the cattle don't contribute to deforestation. ”
As early as 2007, Michael Griffin, former Administrator of NASA, put forward the concept of the “space economy” in a speech. He is very optimistic about the market prospect of commercial space and said, “According to the latest data, the global space industry could reach $1 trillion in 2040, up from $ 378 billion currently. I believe more business models and space activities will be created in the future to achieve the economic scale of $1 trillion. ”
As an entrepreneur(创业者)herself, Victoria thinks the thriving space market will bring countless opportunities for entrepreneurs. She mentioned future settlements on Mars or on the Moon. “If we are going to develop a new society outside the Earth, we will need all types of applications and all types of startups. But coming back to the Earth, there are so many problems that need to be solved, and space technology can really help with that.”
