Move Earth—it’s no science fiction
LONDON—Scientists have found an unusual way to prevent our planet from overheating: move it to a cooler spot. All you have to do is send a few comets（彗星）in the direction of Earth, and its orbit will be changed. Our world will then be sent spinning into a safer, colder part of the solar system.
This idea for improving our climate comes from a group of US National Aeronautics and Space Administration（NASA） engineers and American astronomers. They say their plan could add another six billion years to the useful lifetime of our planet—effectively doubling its working life.
The plan put forward by Dr Laughlin, and his colleagues Don Korycansky and Fred Adams is designed to carefully direct a comet or asteroid（小行星） so that it passes close by our planet and sends some of its gravitational energy to Earth.
“Earth’s orbital speed would increase as a result and we would move to a higher orbit away from the Sun,” Laughlin said.
Engineers would then direct their comet so that it passed close to Jupiter or Saturn. The comet would pick up energy from one of these giant planets. Later its orbit would bring it back to Earth, and the process would be repeated.
In the short term, the plan provides an ideal way to global warming, although the team was actually concerned with a much greater danger. The sun is certain to heat up in about a billion years and so “seriously compromise” our biosphere（生物圈）by cooking us.
That’s why the group decided to try to save Earth.
The plan has one or two worrying aspects, however. For a start, space engineers would have to be very careful about how they directed their asteroid or comet towards Earth. The smallest miscalculation（误算）in orbit could fire it straight at Earth—with deadly consequences.
There is also the question of the Moon. As the current issue of Scientific American magazine points out, if Earth was pushed out of its current position, it is “most likely the Moon would be stripped(剥去) away from Earth,” it states. This would greatly change our planet’s climate.What makes the scientists plan to move Earth?

Manage your time well for each module(单元), but also make sure you get a good balance(平衡) between work and social life. That is vital for life in general.
Set aside time specifically for each subject. Try to study one subject a day. You need to balance time. If you are bad at balancing things, make a personal timetable. Even if you do not stick to it, you will have an idea what you should be doing each day. This is better than trying to do everything each day and, at the end of the week, not achieve anything. Also, try to keep your weekends free of studying. Only study at the weekend if you really have to.
I had to learn to balance work, study and family when I was at college. I was a retail assistant working part-time and had at least four modules to complete at the same time at college. I also had to help around the house doing household cleaning and shopping at times. I managed to finish my college work on time, which was very difficult and hard, and still hold down a job.
Why was it possible? Because I only thought about my part-time work when I was at work on the weekends and my college work had to be done from Mondays to Fridays before the weekends. This was hard—but you need to set a timetable for yourself. It was an achievement when I finally realized that things have to be done in order, and need to be organized as well.
Balancing study and other aspects(方面) of your life can be a problem if you have a job or a family, but planning in advance is helpful. Use the time you have well. Do not leave anything until the last minute, as this will only cause problems.The underlined word“vital”(in Paragraph 1) means_____________.
| A．common | B．necessary | C．easy | D．difficult |
According to the passage, which of the following is NOT the advice the writer gives?
| A．Try to study many subjects in a day. | B．Try not to study on the weekends. |

| A．the writer has a part-time job as an assistant when he was at college |
| B．you need to set a timetable for yourself |
| C．you should make a personal timetable if you are bad at balancing your time |
| D．the writer can arrange（安排） his time well when he was at college |
What is the passage mainly about?

It was several years since Adolf Hitler came into power in Germany. And now his army was marching into some parts of Europe. He must be in the prime of his career.
One day Hitler went to an exhibition where the works of school children were on show. He seemed to have great interest in the exhibits—inventions as well as carvings, drawings. After having walked around the hall and examined everything, he said he was ready to meet the young artists. And soon a group of children came into the room to salute(向-----敬礼) him.
