In the future, people may travel to Mars (火星) by water-powered spaceship! Today's spaceships are fine for getting things into space, but they are not so good at travelling long distances. These spaceships burn chemical fuels (燃料) and they are very expensive. Scientists say that a water-powered spaceship could make the trip to Mars much cheaper. The idea is just in the planning stages now, but scientists think such a spaceship could be developed soon.
The key to the water-powered spaceship is the engine (发动机). Regular engines push spaceships by burning fuel. The water engine will use steam, created by solar panels (太阳能板) that heat water to a high temperature. Of course, the spaceship will have to carry a lot of water for the long trip to Mars.
Today's spaceships could not carry that much water. But scientists think that a spaceship blown up like a balloon will be able to.
One US company has already developed a spaceship like this. These spaceships are made of a strong material. Two of them have already been sent up into space, using rockets and then later filled with air. "Balloon" spaceships could be very large and carry enough water for a long trip. With the "Balloon" spaceships, enough water could be carried to power the engines and grow food during the trip. And the people on the spaceship might even get to take a hot bath!
Scientists say the biggest advantage of such a spaceship would be cost. The "Balloon" spaceship uses water to push it through space and costs about one thirtieth of a normal spaceship. Such savings naturally encourage continued research into balloon spaceships and water engines. If these scientists are correct, we may soon be on our way to Mars in a spaceship powered by water.

Robots Are Now Teaching English! Get ready. Robots are about to invade our classroom. From Korea to Japan to the United States, schools are putting English-speaking robots in front of their students. In Korea, robots are the new teaching assistants in a number of preschools and kindergartens. The young students say that the robots are fun, but are these children really learning anything? I don't think a computer will ever be able to do what a teacher does. A teacher has to be able to respond to students as individuals (个体) . _______▲_______, and a teacher has to change his or her teaching style to fit the needs of the student. I seriously doubt that a computer will ever be able to do this even though the big data (数据) is widely used in the world. |

Sara says: In my opinion, schools should spend money training human teachers rather than buying robots. Research shows that children learn more from real speakers than from recorded conversations. Keiko says: I don't think you can learn a language without real human interaction. After all, robots cannot think as humans do. Hassan says: Robots might be able to help people learn a language, but I don't think they should replace teachers because robots are just machines without human feelings. Nancy says: I think robots might be very helpful in the classroom. A child might be less afraid to make a mistake in front of a robot than in front of a real person. | |

I'm a virus (病毒) for the common cold. It has been a long time since I infected (感染) humans last time. Today I tried to infect a boy in a primary school all day.
His name is Sam. I waited on his desktop, and when he touched the desk I jumped on his finger. Unluckily, Sam didn't touch his eyes, mouth or nose. Then, right after class, he washed his hands. Now I'm full of soap and sitting in a sink!
Tuesday, January 22nd
This morning I jumped into the nose of Sam's best friend, Bill. Unluckily, the mucus (粘液) in his nose caught me. I thought it was over for me, when suddenly Bill sneezed while he was talking to Sam.
I knew that would send me right into Sam's face! However, Sam quickly gave Bill a tissue, and Bill sneezed into that instead! Infecting people is harder than I imagined.
Wednesday, January 23rd
I'm feeling very unhappy today. Some scientists caught my friend Harry and put him under a microscope. Harry is a flu virus and he's a dangerous little guy. Besides, Sam at all his vegetables today. He's exercising, and he's getting eight hours of sleep every night. His body is too strong for me!
Thursday, January 24th
I tried to infect Sam again today, but he washed his hands five times and never touched his face! He also gave tissues to every student in his class who was sneezing. It's impossible to give him a cold! So I have to give up and I'm moving to another school.
