If you look at the sky one night and see something moving and shining that you have never seen before, it might be a comet (彗星).
A comet sometimes looks like a star. Like a planet, a comet has no light of its own. It shines from the sunlight it reflects (反射). Like the earth, a comet goes round the sun, but on a much longer path (轨道) than the earth travels.
If a comet isn’t a star, what is it then?
Some scientists think that a large part of a comet is water frozen into pieces of ice and mixed with iron and rock dust and perhaps a few big pieces of rock. When sunshine melts (融化) the ice in the comet, great clouds of gas go trailing after it. These clouds, together with the dust, form a long tail.Many people perhaps have seen a comet. However no one knows how many comets there are. There may be millions of comets, but only a few come close enough for us to see.
An Englishman named Edmund Halley, who lived from 1656 to 1742, found out a lot about the paths that comets take through the sky. Some comets move out of our sight and never come back. Others keep coming back at regular times. A big comet that keeps coming back was named after Halley because he was the one who worked out when it would come back again. Maybe you have ever seen Halley’s Comets because the last time it came close to the sun and the earth was in the year 1986. Then people all over the world were outside at night to look at it. You will probably be able to see Halley’s Comets when it comes near the earth again.
1.A comet is like ________.
A. sun B. moon C. sunlight D. the earth

九年级英语单选题中等难度题查看答案及解析
In the sunny night, look up at the clear night sky. You can probably see thousands of stars. The biggest thing you’ll see, of course, is the moon. For thousands of years, people have wondered about this big thing in the sky.
Earth’s moon is a satellite. A satellite is a body that orbits(环绕轨道运行)a planet. All moons are satellites, and many planets have them. Some have many moons. Earth, of course, only has one. It’s a special moon, though. It’s the fifth largest moon in the solar system!
In fact, the moon is much smaller than the sun. But it’s much closer to Earth, so it looks as big as the sun. The moon is so close that you can see its dark and light spots(斑点)without a telescope. Men flew and landed on the moon’s surface many times by spacecrafts in the 1960s and 1970s. Neil Armstrong was the first human to step on the moon. He walked on the moon on July 20th, 1969. The flights to the moon have helped us learn much about it. Astronauts even brought rocks home with them!
There’s still a lot to learn about the moon. Now people still can’t live on the moon because it does not have oxygen or water like the Earth. But I’m sure that humans can live there one day in the future.

If you watch the sky for about an hour after the sun goes down, you may see some “moving stars”. But they’re not real stars. They’re man-made satellites(人造卫星). And the biggest of all is the International Space Station (ISS). From May to July is the best season to watch the ISS flying over the earth. And people can see it with their eyes.
The ISS is the biggest satellite and scientists want to live on it. They think that the best way to learn more about space is to live there.
When the space station is finished, it will be like a city in space. People will stay and study there with many of the things they have at home. Laboratories, living rooms and power stations are being built. The ISS is the most expensive space program. Billions of dollars are being spent on it every year.
Scientists hope that the ISS will be a stepping stone for future space exploration(探测). “The ISS will help us understand the human body better, explore space and study the earth. It can help us make life on the earth better,” said Kathryn Clark, an ISS scientist.
Sixteen countries are part of the program: the US, Russia, Canada, Japan, Brazil and 11 European countries. China isn’t an ISS country, but it has helped with some of the experiments. In 2003, China sent some rice up to the ISS to find out what space would do to it.
根据短文内容,选择正确答案。
1.The International Space Station_____________.
A. is really a big city in space B. is the biggest man-made satellite
C. can only help us explore space D. is mainly built by the USA and Russia
2.From the passage we know that_____________.
A. building the ISS is only for scientists to live there
B. scientists can do anything they like there
C. people can see the Space Station at any time
D. sixteen countries are members of the space program
3.China sent some rice up to the ISS is probably to_____________.
A. be used as astronauts’ food B. sell it to aliens
C. do some science experiments D. make it grow better in space
4.Which of the following isn’t mentioned ?
A. China will join the ISS in the future.
B. The scientists are building living rooms for them in the ISS.
C. The ISS will be more useful in the future.
D. The ISS costs the members of 16 countries plenty of money every year.

九年级英语单项填空中等难度题查看答案及解析
The next time you look up at the sky and see a cloud that looks like Mickey Mouse or your favorite fruit, look again. It may not be a cloud, but a Flogo -- a logo that flies. It's a new form of advertising in the sky that's never been used before. It's a different way to market your products, logos, and events.
These funny logos are made with soap bubbles (肥皂泡) mixed with a little helium gas (氦气) ,which makes them lighter than air and float in the sky. Special machines are used to make these new funny Flogos. The machine, which can be rented for $ 2,500 a day, can make a Flogo every 15-25 seconds.
Flogos can fly much higher or lower if needed. They can last from a few minutes to an hour anywhere in the sky, depending on the weather conditions. Though they can fly up to 20, 000 feet, they usually float around at 300- 500 feet. Flogos are only white now, but people hope to have more colorful Flogos in the near future.
Flogos are Green, 100% environmentally safe, because the soap used to make the Flogo comes from plants and leaves. So this fun way of advertising is healthy and good for the environment.
1.Flogos are mainly used to _____.
A. advertise in the sky B. make funny bubbles
C. improve weather conditions D. see colorful clouds
2.Why are Flogos healthy and good for the environment?
A. Because they can float high and last for a long time in the sky.
B. Because there is a little helium gas mixed with soap bubbles.
C. Because the machines used to make them are special and expensive.
D. Because the soap used to make them comes from plants and leaves.
3.From the passage, we can infer that Flogos _____.
A. can fly for hours in the sky all day B. can have different colors at present
C. may be influenced by the weather D. may be the cheapest way of advertising
4.Which of the following can be the best title of the passage?
A. Machines -- Used for Flogos! B. Flogos -- Logos that fly!
C. Advertising -- Made of Fruits! D. Clouds -- Like Mickey Mouse!
