Then he tried to turn around but he couldn’t. “In space, astronauts are in a weightless environment. So we need to use nearby devices (装置) to move,” he said. ※ The paper flower “blooms” In the “Tiangong Classroom,” Wang Yaping made a beautiful water film. Then she took out a paper flower and placed it on the film of water. The pink flower slowly “bloomed”! “I hope your dreams can bloom in the huge universe!” she said. ※ “Space Happy Ball” brings fun Wang Yaping asked the children on the ground to put their ping pong ball in the water. The density (密度) of the ball was less than that of the water, so it floated up. In space, when she put the ping pong ball into the water, it did not float up to the surface. It stopped in the center of the water! “The buoyancy (浮力) disappears in a weightless environment in space so the ping pong ball cannot float,” Ms. Wang explained. 1．Why was it difficult for Ye Guangfu to turn around? A．Because he was working too hard. B．Because he was too tired to turn around. C．Because he was walkin
