No matter how carefully we check a composition(作品), it seems there’s always one more little mistake waiting to be discovered. The following tips may help you find your mistakes before anyone else does.
First of all, give it a rest. If time is allowed, set your composition aside for a few hours after you’ve finished it, and then read it carefully to correct mistakes with fresh eyes.
Secondly, look for one type of problem at a time. Read through your composition a few times, concentrating first on sentence structures, then word choice, then spelling, and at last punctuation. As the saying goes, if you look for trouble, you’re likely to find it.
If you don’t believe in yourself, you can ask a friend for help. Read your composition to him aloud. You can also ask him to read it aloud. You may hear a problem that you can’t see. Your friend can also help you find some mistakes.
Then, try to read your composition backward. Another way to catch spelling mistakes is to read backward, from right to left, starting with the last word in your composition.
Another method that helps writers a lot is to keep a list of the types of mistakes they commonly make, and then use the list each time they correct their works.

Antarctica (南极洲) is the fifth largest continent on Earth. It is also the coldest, windiest, driest and highest. It is an ice-covered place where no large plants grow, and no land animals live there. Antarctica covers an area of more than 13.6 million square kilometres. It is nearly twice the size of Australia, or one-and-a-half times the size of the United States of America.
Antarctica does not belong to one country, and it has no government. People visit Antarctica – usually as tourists, or to do scientific research – but no one lives there all the time.
Antarctica was the last place to be discovered. It is not certain who first saw Antarctica, but sailors began to map Antarctica’s coast from their ships in the 1800s. The first proved landing was in the mid-1890s.
Over the next few years, several men tried but failed to reach the South Pole, which is the Earth’s southernmost point.
Finally, a team led by Norwegian Roald Amundsen reached the South Pole in 1911. By then, countries around the world were becoming more and more interested in the frozen place, and soon Argentina, Australia, Chile, France, New Zealand, Norway and the United Kingdom had laid claim（声称）to parts of Antarctica.
As so many nations had made a claim to govern in Antarctica, it was clear that fighting might break out. Diplomats(外交官) from different countries wanted to stop a war from starting, so they began talking about a treaty for Antarctica. A treaty is a written agreement signed by two or more nations.
Several countries had already set up research stations in Antarctica where scientists could live and work. Most scientists worked during the summer months when it was not as cold as in winter. Scientists hoped a treaty would allow them to continue their work and to exchange information with scientists from other countries.

Most people have map apps on their phones that can show their locations and guide them to where they want to go. But how do these app systems know your location at any time or place? They find you by using satellite navigation system(卫星导航系统).
A navigation system uses groups of satellites to find the user’s locations. This location information is then sent to a receiver.
The first navigation system is the Global Position System(GPS)(全球定位系统), which belongs to the United States. The system is the world’s famous navigation system. But China’s satellites are important for improving the navigation system. Beidou, has overtaken(超过) GPS in size, Japan’s Nikkei Asian Review reported.
China sent Beidou’s first navigation satellite into space in 2000. China also became the third country to build a navigation system after the United States and Russia, People’s Daily reported. As of right now, over 30 countries in Africa and the Middle East are using the Beidou system.
With its world-leading technology, Beidou is leading Chinese people to a better life by playing important roles in different areas, according to Xinhua News.
For example, over 6.2 million vehicles in China are using Beidou for navigation, according to a report on the Beidou system’s construction and development.
At the newly built Beijing Daxing International Airport, Beidou has been used to keep track of(追踪) loading and unloading vehicles indoors and outdoors. When the airport opens, each baggage cart has Beidou navigation equipment to help passengers get their luggage faster.
For a navigation system, the number of satellites is important for improving the system’s positioning accuracy(定位精度). The more satellites, the more accurate the positioning is. The satellite navigation system is useful in many ways.
1.What does a navigation system use to find a user’s location?

2.Which of the following statements is NOT true according to the passage?
A.GPS is the first navigation system in the world.
B.Beidou system has world leading technology.
C.GPS is much larger than Beidou System.
D.To make the positioning more accurate, we need more satellites.
3.Nikkei Asia Review may be _______.
A.a newspaper B.a satellite C.a navigation system D.an airport
4.How many countries have built navigation systems before 2000?
A.Three. B.Two. C.Over 30. D.One.
5.At Daxing International Airport, Beidou helps _______.
A.to open the doors B.to find the luggage more quickly
C.to improve the positioning accuracy D.to build the new airport
