四、阅读理解(每小题2分，共20分)

A

Venus (金星) is the second planet from the Sun and the hottest planet in our Solar System. Its temperature can reach about 460°C, which is hot enough to melt lead (铅).

Is there life on Venus? Most scientists think it is impossible because the atmosphere is full of carbon dioxide and sulphuric acid (硫酸). There is no oxygen for humans to breathe. The air pressure is 90 times heavier than on Earth.

However, some scientists believe that there might be tiny organisms (微生物) in the upper atmosphere, where the temperature and pressure are milder. They have found a gas called phosphine (磷化氢) in Venus’s clouds, which on Earth is produced by living things.

Venus has no seasons like Earth because its axis (轴) is almost straight. It rotates very slowly — one day on Venus is longer than its year.

Through a telescope, Venus looks yellowish white. Its thick clouds reflect sunlight, making it the brightest planet in our sky.
