1 . 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.

I often imagine what I will be in the future. I desire to work as a computer program designer, for I am crazy about designing computer programs and had won first prize in software designing contests three time. Besides, I find it excited to work out a program for which is beneficial to our life. What makes us satisfied with this job is because it will provide me with flexible time. As result, I can spare time to keeping my family company. No matter how hardly it is, I will ever give up halfway.
3 . 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 |
