China on Thursday successfully launched space lab Tiangong-2 into space, meaning another historic step towards building a manned space station around 2020.
Measuring 10.4 meters in length, the tube-like Tiangong-2 is designed to enable two astronauts to live in space for up to 30 days and to receive spaceships.
Once inside Tiangong-2, two astronauts arriving from the Shenzhou-11 spaceship will carry out key experiments related to in-orbit equipment repairs, aerospace medicine, space physics and biology, such as space clocks and solar storm research. The number of experiments carried out by Tiangong-2 will be the highest of any manned space mission (航天任务) so far.
The successful launch of the Tiangong-2, along with the first flight of China’s new generation carrier rocket Long March-7 in June, bodes well for the final stage of China’s three-step manned space plan.
The first step, to send an astronaut into space and return safely, was fulfilled by Yangliwei in the Shenzhou-5 mission in 2003. The second step is developing advanced space flight technologies, including the launch of two space labs. Finally, the third step will be to operate a manned space station.
Once the space lab mission comes to an end, China will start building our own space station, which is planned for completion by around 2020. The Chinese space station will be much smaller than the current International Space Station (ISS), but it can be expanded for scientific research and international cooperation. With the ISS set to retire in 2024, the Chinese station will offer a promising choice, and China will be the only country with a permanent (永久) space station.

Spanish artist Pablo Picasso (1881—1973) is one of the greatest artists of the 20th century. It is said that everything his brush touched turned to gold. But in truth, the value of his work could be worth more than any precious metal. Picasso created more than 20,000 works in his life, including two of the world’s 10 most expensive paintings.
Between 1907 and 1913, Picasso and his colleague(同事) Georges Braque started a revolution(革命) in painting. Before that, paintings were like windows — they were painted to look as if they had depth. You could tell which objects were “close” to you and which objects were “far away”. But Picasso and Braque didn’t want to paint like that any more. To them, a painting wasn’t a window to the world; it was marks and lines on a flat surface. Why, they thought, should an object like a guitar be shown only from one angle (角度)? A guitar can look very different depending on which angle one looks at it from. Their answer was to show all the angles. They broke the guitar up into pieces. Their style of painting is called cubism.
But why did they feel such a need to change things? Well, the world around them was changing, too. Science was turning people’s ideas upside down. Albert Einstein’s theory was proving that what we knew about time and space was wrong. And new political movements like socialism were on the rise. The world was becoming different; artists needed to start seeing and painting it differently.
The famous and terrifying painting Guernica (1937) shows the horror of the bombing(轰炸) of the town of Guernica during the Spanish Civil War. In the painting, you can actually see the sky falling. Picasso couldn’t have painted it without the skills he learned during his cubist period. Breaking a guitar into pieces was his preparation for showing the world being blown to pieces.
1.What is the article mainly about?
A. The high price of Picasso’s paintings. B. Picasso’s difficulties in career.
C. The popularity of Picasso’s paintings. D. Picasso’s achievements in art.
2.In what way did Picasso and Braque paint?
A. They painted objects with different depths.
B. They made their paintings look like windows.
C. They painted an object from different angles.
D. They broke objects into pieces and painted them.
3.What caused Picasso and Braque to start cubism?
A. Einstein’s theory. B. The changing world.
C. The rising socialism. D. New political movements.
4.The painting Guernica is mentioned to show _______.
A. the themes of Picasso’s paintings B. the anger of Picasso at the war
C. the preparations Picasso made before D. the artistic effect of cubism
Easy floating
If you have ever been swimming in the ocean, you may have noticed that sea water is easier to float in than pool water. Here’s why:
You’ll need
Two clear bowls Food coloring Spoon Salt Two eggs
1. Fill bowls halfway with water.
2. Add 10 tablespoons of salt to one bowl, mix until it dissolves, and then add several drops of color.
3. Carefully put an egg into each bowl of water, and watch what happens.
What happens?
The egg in the plain water sinks. The egg in the salt water floats.
(If the salt water egg does not float well, mix more salt into the bowl. )
The water and salt particles (粒子) in the salt water bowl are closer together than plain water particles are. They press harder against the egg than the plain water particles do and the egg floats.
1.The purpose of the experiment is to explain ________.
A. why the egg floats in the salt water
B. why people float more easily in the sea
C. how we can make the egg float in water
D. how the water and salt particles act together
2.According to the text, if the egg in the salt water doesn’t float, which is the reason?
