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.
小题1: Where should we write the two letters?
小题2:Which letter should be written on the left?
小题3:Which eye do you close when R disappear?
小题4:What will happen if the image (影像) of the letter falls on the blind spot?
小题5:.Do all people know that there is a blind spot (盲点)on their eyes?

What do you think of the most important inventions in the world? The TV? The printing? The telephone? Or the computer? A report shows that they are not the only important inventions. Here are three other important inventions.
One of the simplest(最简单的) inventions is the toilet(冲水式马桶). Before toilets, waste ran into rivers from people’s houses. Illnesses were common in big cities, and it was often difficult to find clean drinking water.
Animal food is another important invention. Before the invention, most animals were killed（***死） every autumn because there was not enough food for them in winter. After hay (干草) became a kind of common animal food, animals could live through the long winter. The third great invention is glasses. Glasses help people read, write and do “close work” after the age of 45. Without glasses, the world would be difficult for the people above 45.
