二、阅读理解。
How much do you know about Uranus? It is one of the eight planets in our solar system. Its color is blue-green. At -200℃, it is the coldest planet in our solar system. And Uranus may be the smelliest(最臭的) planet.
Scientists from the UK find that the clouds above Uranus smell like bad eggs. That's because there is hydrogen sulfide(硫化氢) in the air around the planet. This gas is what makes bad eggs smelly. It also gives Uranus an awful smell.
This is the first time scientists have found this gas on Uranus. It used to be hard for scientists to find out what makes up Uranus' air, because the planet is very far away from Earth. But this time, scientists could use the Gemini North telescope(北双子望远镜) in Hawaii to help them. They used the telescope to take infrared images of Uranus. After looking at these images, scientists found hydrogen sulfide. They hope they can study the air of other planets in the same way in the future.
