5. A plane powered by the sun will attempt an unprecedented flight around the world soon. The attempt is going to prove that flying is possible without using fossil fuel ( 化石燃料 ). Solar Impulse 2 ( 阳光动力 2 号 ) is set to take off from Abu Dhabi ( 阿布 扎比 ) with stops in India, Myanmar ( 缅甸 ) and China. The plane will then cross the Pacific Ocean and fly across the United States and Europe. It will complete its journey where it started in late July. During its five-month journey, the plane will be powered only by solar energy. Two Swiss pilots will take turns at the controls ( 操纵装置 ) in the tiny cabin ( 驾驶舱 ). There will also be a crew of 80 technicians, engineers and a communications team on board. “ Miracles can be achieved with renewables ( 可再生能源 ) such as solar power. We want to show that we can fly day and night in an aircraft without a drop of fuel,” said Bertrand Piccard, one of the pilots. The plane weighs the same as a family car, but has a wingspan ( 翼展 ) equal to that of the largest passenger airliners ( 客机 ). “It is not the first solar airplane, but it is the first able to cross oceans and continents,” Andre Borschberg, the other pilot, said. Of course, there will be a lot of unknown challenges, but nothing will stop the journey. “There is a will in humankind to find solutions to climate change and make a better world,” Piccard added.

6. Comprehension Answer the following questions. 1. How many countries will Solar Impulse 2 stop by? 2. How long will it take Solar Impulse 2 to fly around the world? 3. There will be nobody else except two pilots on board, will there? 4. What is the significant meaning of the flight according to Andre? Three. Five months. Yes, there will. It will be the first solar airplane able to cross oceans and continents.
