The world's largest radio telescope was finished on Sept. 25, 2017 in China.

    FAST is a five-hundred-meter telescope. It is also called Tian-yan ("The Eye of Heaven"), with a dish the sire of 30 football grounds, deep in the mountains of southwest China's Guizhou Province. The giant dish is built on a howl-like valley.

    The surrounding area has "radio silence" as there are no towns and cities within a 5-kilometer radius (半径范围) and only one county center within 25 kilometers.

    FAST is made up of 4, 450 panels (面板). The second largest radio telescope is in Russia. The bigger dish will be able to pick up weaker signals (信号).

    The radio telescope is like an ear, listening to tell meaningful radio messages from white noise in the universe. With the help of the telescope, we can receive weaker and more radio messages far away in space. It will help us to search for intelligent life outside of the Galaxy (银河系) and explore the origins (起源) of the universe. "Any of its discoveries will lead to a Nobel Prize," said Joseph Taylor, a Noble Prize winner.

    The FAST project began in 2011. And the telescope is expected to remain the global leader for the next 10 to 20 years.

    Three kinds of bears live in the United States. They are the black bear, the brown bear, and the polar bear.

    Black Bears

    Black bears are the most common of the three. They live in forests in many different parts of the country. Even though they are known as black bears, they are not always black. Sometimes they are brown or tan (黄褐色的) , and a few are even white. Black bears are usually about five or six feet long, and they are the smallest of the three kinds of bears.

    Brown Bears

    Brown bears are found in a few western states and in Alaska. They live in forests as well as in open areas called the tundra (冻土地带). Brown bears are usually light or dark brown and can grow to be very large. In fact, some are eight feet long!

    Polar Bears

    Polar bears can be found in Alaska. It is in a cold area near the North Pole called the Arctic and there are no trees there. Polar bears are white, and they are the largest of the three kinds of ears. They are a little longer and usually heavier than the brown bear.

    Other Interesting Things

    Bears eat different things. Black and brown bears eat fish and other kinds of meat, roots, and berries. Polar bears eat fish, other meat, seaweed, and grass. All three types of bears eat as much food as they can find just before winter. Then during the cold months, they sleep in caves or hollowed-out trees called "dens". They keep them warm. Winter is when the female bears have their babies. All three types of bears have between one and four cubs (幼兽). The cubs are born while the mother bear sleeps!

    All people are afraid of bears. However, bears are actually shy. Most bears try to stay away from people, but still, bears can be dangerous at times.

A..Have the willingness to change an opinion in the face of better data. 

B.Reading is a good way to stay open-minded.

C.A system can be measured,refined,and optimized.

D.The better we get at writing the better we get at thinking.

There is no quick hack to becoming a critical thinker but there are some habits that one can build to after their character in the right direction.

● Read a lot and read widely

{#blank#}1{#/blank#} Well read people understand that there are different ways to look at a problem and different lenses with which to view the world.

● Don't jump to conclusions

A good critical thinker has built up the habit of not jumping to conclusions especially when there is no data.{#blank#}2{#/blank#}

● Create systems,not goals

For example,creating a system habit that promotes writing every day is more effective than setting the goal of writing an essay a week. {#blank#}3{#/blank#}.A goal only focuses on the outputs.

●{#blank#}4{#/blank#}

Great thinkers routinely and intelligently try to counter their own arguments.They go back and forth until only the most rational and strongest argument exists based on the knowledge they have.

● Write

Writing is thinking. {#blank#}5{#/blank#}.Writing also helps us separate what we actually know from what we think we know.

Harbin is the capital (首都) city of Heilongjiang. Many people like Harbin because of its winter tourism (旅游). Last winter, people talked a lot about Harbin on the Internet.

To make visitors feel welcome, Harbin did a lot of things. At the airport (机场), there were shows to watch. And visitors could get warm clothes to wear in dressing rooms. Local (当地的) people also helped a lot. When they were not busy, they went out to give free rides to visitors. When some tourists couldn't find hotels, the local government (政府) let visitors stay in their service center at a low price.

Many of the tourists were from southern China. It doesn't snow very often there. They dressed themselves like potatoes and many of them are shorter than the people in Heilongjiang. So the local people called them "southern little potatoes". The nickname (绰号) quickly became popular on the Internet. The tourists liked the nickname and shared their warm experiences of Harbin. A girl left a note at the hotel, saying, "This southern little potato is leaving. Harbin is so beautiful. The people are so friendly. I can't wait to come back again. Yours, southern little potato." After people saw this note online, "the southern little potato is leaving" became a hot topic, and more and more people shared their trips.

Come to Harbin and experience the wonder of ice and snow this winter!

Many people do not read the classics. Their reasons begin with the language being too difficult and end with the storyline being too far from our present life. Love for great books is not at first sight. It might take you some time to do it. We begin as strangers and become close friends at last. {#blank#}1{#/blank#}

Research, research, research. Before you turn to page one, do some digging. Researching the background can help you read difficult passages. The writer's experience, opinions, and historical background might help you make the connections you might not have. 

{#blank#}2{#/blank#}The order of the story and the plot(情节) are important in the same way.Make sure that as you read, you make a quick note of what happens in each part. This will help you bring the things you have noticed about the character, setting(场景), language and so on together. It's also a great help for you to retell the story.

{#blank#}3{#/blank#}Great books are written by famous writers, many of whom are known for their excellent writing skills. Some of them use language in a special way to make stories work.

Remember: there is no right answer. There is no perfect way to read a classic text. Your goal as a reader is to find out what subjects and ideas are meaningful to you. {#blank#}4{#/blank#}Consider what you like, read with a purpose, and think independently. Even if your understanding of the work isn't quite perfect, it is still worthy!

A. It's your own reading, so just enjoy it.

B. So how does one start to read and love the classics?

C. You need to find out how the story begins and ends

D. Enjoy the beauty of language itself. 

E. Pay attention to the plot of the story
