It seems to be strange to you there is a blind spot (盲点)on the eyes. Here is an interesting experiment (实验) that can make something disappear(消失) when one eye is open.
Make a card which is as big as a postcard, and write two English letters L and R on it. Write L on the left and R on the right. First, hold the card about 80 cm(厘米) away and you see both the letters. Then close your right eye and look at the letter R only with your left eye. And now, as you move the card slowly towards you, you’ll find the letter L disappearing. But if you move the card nearer to your face, the letter will be seen again. Now do the same experiment with your left eye closed, you’ll find the letter R disappearing.
Why does the letter disappear? It is because there is a blind spot on the eye. When the image (影像) of the letter falls on the blind spot, it won’t be seen. That is why either of the letters disappears.
1. Where should we write the two letters?
2.Which letter should be written on the left?
3.Which eye do you close when R disappear?
4.What will happen if the image (影像) of the letter falls on the blind spot?
5..Do all people know that there is a blind spot (盲点)on their eyes?

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.”
