What’s the red star in the sky through a telescope(望远镜)? It is Mars. Do you want to know more about it? Take the “Mars Orbit Express”!
“Mars Orbit Express” is a space probe (探测器). It was sent towards Mars by American scientists on August 12th，2005. Its tasks are to study Mars’ atmosphere and return photos to Earth. But before that “Mars Orbit Express” must travel about 100 hundred million kilometers and seven months. It reached Mars’ orbit(轨道)in March，2006.
Mars and Earth have similar weight and size. However，Mars is closer to the sun than Earth. Mars is very cold. The average temperature is below 50℃. The temperature at noon only reaches 20℃ during a Mars day. Its atmosphere is mostly CO2. It has much sand and two moons---Phobos and Deimos.
Scientists think Earth and Mars had similar beginnings 4.6 billion years ago. But while Earth supports millions of lives，Mars becomes bad. “Earth easily could have turned out like that.” said an scientist, “It is important for us to find out why and Mars Orbit Express’ should do that.” “Mars Orbit Express” also would help scientists to learn what might happen to Earth in the future. “Mars Orbit Express” would work for about four years.

There are many unusual hotels around the world. In Greenland(格陵兰岛), there is a hotel made of ice, open between December and April every year. In Turkey(土耳其), there is a cave(岩洞) hotel with a television, furniture, and a bathroom in each room. And in Bolivia(玻利维亚), there is a hotel named the Salt Palace Hotel.
Thousands of years ago, the area around the Salt Palace Hotel was a large lake. But today, the area has only two small lakes and two salt deserts(荒漠).
The larger of the two deserts is called Uyuni salt desert. During the day, the desert is bright white because of the salt. There are no roads across the Uyuni desert, so local people must show guests the way to the hotel.
In the early 1990s, a man named Juan Quesada built the hotel. He cut big blocks of salt from the desert and used the blocks to build it. Everything in the hotel is made of salt: the walls, the roof(屋顶), the tables, the chairs, the beds, and the hotel’s bar.
The sun makes the walls and roof warm during the day. At night the desert is very cold, but the rooms are warm. The hotel has twelve rooms. A single room(单人间) costs＄40 a night, and a double room(双人间) costs＄60.
A sign on the hotel’s wall tells guests, “ Please don’t lick（添）the walls.”
