2 . Time Travel
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 science fiction The Time Machine, which was written by H. G. Wells and published in 1895 for the first time. It was adapted for at least two feature films of the same name, as well as two television versions, and a large number of comic book adaptations. The term “time machine” , invented 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 theoretical physicist Stephen Hawking says you could travel into the future with a really fast spaceship going at nearly the speed of light.
Even if you could travel into the past, there is something called the “grandfather paradox”. It asks what would happen if a time traveler 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 traveler 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. He arrives at a beach where he 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.

3 . What makes a human being? Is it our thoughts? Our emotions? Our behavior?
All of these things make us who we are, but at the center of the matter is the genome (基因组) — the genes inside our bodies that may determine everything from our hair colour to our intelligence. But if we could change our genome, what would it mean to us?
In an online video posted on Nov 26, He Jiankui, a biological researcher from Southern University of Science and Technology in China, said that he had helped to make the world’s first genetically edited babies.
These are twin girls, born in November, with genes edited in an attempt to help them fight against possible future infection (感染) with the AIDS virus.
He said that he chose to do this because HIV infections are a big problem in China. “I feel such a strong responsibility that it’s not just to make a first, but also to set an example,” He told the Associated Press(AP).
The announcement has caused an international storm. Some believe that success will benefit the families of HIV patients. Considering that HIV is “a major and growing public health threat,” attempted gene editing for HIV is justifiable, Harvard Medical School genetics professor George Church told AP.
However, others think that gene editing technology is still unsafe to attempt.
“Gene editing itself is experimental and is still associated with unexpected mutations (突变), causing genetic problems early and later in life, including the development of cancer,” Julian Savulescu, a specialist in ethics at the University of Oxford, told BBC News.
Others fear that this could open the door to using gene editing technology to make designer babies. It might give the parents the choices to choose everything from their baby’s eye color to intelligence.
“You could find wealthy parents buying the latest ‘upgrades’ for their children, leading to even greater inequality than we already live with,” Marcy Darnovsky, director of the San Francisco Center for Genetics, told BBC News.
However, Merlin Crossley, a biologist at the University of New South Wales, Australia, believes that’s a long way off. According to him, many genes produce qualities like height and intelligence — not to mention environmental influences.
And he believes the technology will be better controlled in the future.
“It’s hard to get genies (妖怪) back into bottles — but I’m optimistic that this technology, which I think of as ‘genetic surgery’, could be controlled quite effectively in the future,” Crossley told ABC News.
1. Why did He Jiankui make the genetically edited babies?| A．Because he wanted to be a leader in gene editing technology. |
| B．Because he tried to do his part in fighting against HIV infection. |
| C．Because he attempted to help the twin girls who were infected with AIDS. |
| D．Because he wanted to became the first to make the genetically edited babies in the world. |
| A．Gene editing can cause genetic problems sooner or later in life |
| B．Gene editing may widen the gap between the rich and the poor |
| C．Gene editing may enable wealthy parents to design their babies |
| D．Gene editing can determine everything inside a person’s body |
| A．Absurd. | B．Hopeless. | C．Acceptable. | D．Skilful. |
| A．Gene editing: the genie in the bottle |
| B．Gene editing: the way we should go |
| C．Gene editing: hope or fear for human beings |
| D．Gene editing: a great success in human history |
4 . The sea could be the food bowl of the future. In Jervis Bay, south of Sydney, seaweed, which is rich in fibre and omega 3, is grown and harvested.
Pia Winberg is a marine scientist who runs Australia's first food-grade fanned seaweed company. Her crop is grown alongside mussels (贻贝)and is used as an additive in pasta (意大利面)and other products.
Seaweed is also raised in large tanks, where it absorbs carbon dioxide waste from a wheat processing factory. The business is small, but could help to reduce the ecological footprint of traditional farming.
“We used ten percent of seaweed instead of wheat in breads and pastas, we've eliminated a million hectares of land, we've eliminated all of the carbon dioxide emissions associated with that, and we've also reduced the pressures on very precious fresh water.” said Pia Winberg.
Spiny sea urchins (多刺海胆虫)are another blue economy resource. They can destroy marine habitats, but a recent competition for environmental start-ups in Australia, saw them not as a pest but a delicacy (美味).
Martina Doblin, CEO of Sydney Institute of Marine Science, said, “By 2050 we will have some ten billion people on the planet, and about half the food they eat will come from the ocean. So, we really do need to pay attention to the way that we manage the blue economy-generating wealth from the ocean but in a sustainable (可持续的)way.”
Farming at sea has its challenges. Infrastructure (基础设施)has to be sound, as do supply chains and biosecurity. But get these things right, and the ocean might just be the next great economic frontier.

| A．How to Protect the Marine Animals |
| B．Measures to Develop Blue Economy |
| C．Farming the Sea for the Future of Food |
| D．Traditional Farming is Gradually Disappearing |

6 . Do you want to live another 100 years or more? Some experts say that scientific advances will one day enable humans to last tens of years beyond what is now seen as the natural limit of the human life span.
“I think we are knocking at the door of immortality(永生),” said Michael Zey, a Montclair State University business professor and author of two books on the future. “I think by 2075 we will see it and that’s a conservative estimate(保守的估计).”
At the conference in San Francisco, Donald Louria, a professor at New Jersey Medical School in Newark said advances in using genes as well as nanotechnology(纳米技术) make it likely that humans will live in the future beyond what was possible in the past. “There is a great effort so that people can live from 120 to 180 years,” he said. “Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years.”
However, many scientists who specialize in aging are doubtful about it and say the human body is just not designed to last past about 120 years. Even with healthier lifestyles and less disease, they say failure of the brain and organs will finally lead all humans to death.
Scientists also differ on what kind of life the super aged might live. “It remains to be seen if you pass 120, you know; could you be healthy enough to have good quality of life?” said Leonard Poon, director of the University of Georgia Gerontology Centre. “At present people who could get to that point are not in good health at all.”
1. By saying“we are knocking at the door of immortality”,Michael Zey means_________.| A．they have got some ideas about living forever |

| C．it is still doubtful how long humans can live |
| D．people can live from 120 to 180 |
| A．a great effort |
| B．the conservative estimate |
| C．the idea of living from 200 to 300 years |
| D．the idea of living beyond the present life span |

8 . These days, it seems like everyone wants to go out into space and live on new planets.Rather than depend on another pre-existing planet, could we make a new, proper planet ourselves?
To start with, if we do want to be living on it, we should find a good place in space to put the new planet. We’d want it to be in a habitable zone, meaning the planet should be at the right distance from its star to make sure there would be perfect temperatures and most importantly, liquid(液态的) water.
We’d also need the right materials to make the planet. Our Earth is made up of many different elements(元素). If we made our own new planet we’d probably want it to have similar elements and a similar structure(结构) We’ d also want enough water to form some oceans.
But even if we get all of the materials creating a new planet like Earth could have many troubles. It might be something more like a huge space station. It would be pretty expensive if we wanted it to be super big.
We would probably also need a lot of food since there s going to be many scientists and astronauts out in space working on this project!
According to NASA, each astronaut uses about 0. 83 kilograms of food per meal, including 0.12 kilograms of packaging(包装) material. Without the weight of the packaging material, we’d need about 780 kilograms of food just to feed one astronaut for a year.
Putting all these together could make it possible to make our own planet one day! In reality, creating a new planet would probably require a very modern technology and there would be tons of other things to think about. And if this is even possible, it likely won’t happen for a very long time.
1. What's the first thing we should do if we want to create a new planet?| A．To prepare enough food. |
| B．To design its inner structure. |
| C．To find a proper place to set the planet. |
| D．To collect materials similar to our Earth. |
| A．Our Earth. | B．Outer space. |
| C．The new planet. | D．The ocean water. |
| A．About 0. 12 kilograms. | B．About 0. 71 kilograms. |
| C．About 0. 83 kilograms. | D．About 0.95 kilograms. |
| A．It is a waste of money and time. | B．It should be one of NASA’S next plans. |
| C．It is not a good idea for humans. | D．It won’t come true in the near future |
