[导语]科技发展迅速，将来人类会制造星球吗？请看下文。
These days, it seems like everyone wants to go out into space and live on new planets.Rather than depend on another preexisting planet, could we make a new, proper planet ourselves?
To start with, if we'd 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 are 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？ C
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.
解析：细节理解题。由第二段首句“To start with, if we'd want to be living on it, we should find a good place in space to put the new planet.”可知，想要制造一个行星，首先要在太空中找到安置这个行星的合适的位置。
2．What does the underlined word“it”in Paragraph 3 refer to？ C
A．Our Earth. B．Outer space.
C．The new planet. D．The ocean water.
解析：代词指代题。本段主旨句是“We'd also need the right materials to make the planet.”即本段在介绍制造新行星所需的材料，可推知画线词所在句意为“制造的新行星需要有和地球相似的元素和结构”，故此处的 it 指制造的新行星。
3．How much food does an astronaut actually eat each meal？ B
A．About 0.12 kilograms.
B．About 0.71 kilograms.
C．About 0.83 kilograms.
D．About 0.95 kilograms.
解析：推理判断题。由倒数第二段中的“each astronaut uses about 0.83 kilograms of food per meal, including 0.12 kilograms of packaging(包装) material”可知，去掉0.12公斤的包装材料，一个宇航员每顿实际上吃了0.71公斤的食物。
4．What does the author think of creating a planet？ D
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.
解析：推理判断题。由文章最后一段中的“if this is even possible, it likely won't happen for a very long time”可知，作者认为制造星球即使有一定的可能性，也不会在短期内实现。
