Passage 2

　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, when one eye is open.

　Make a card about the size of a postcard and write two English letters L and R on it, L on the left and R on the right. First, hold the card about 80 cm 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.

Passage 1

　Henry was an office worker in a big city. He worked very hard and enjoyed traveling in his holidays.

　He usually went to the seaside, but one year he saw an advertisement in a newspaper. “Enjoy country life. Spend a few weeks at West Hill Farm. Good food. Fresh air. Horse riding. Walking. Fishing. Cheap and interesting.”

“This sounds a good idea,” he thought. “I’ll spend a month at West Hill Farm. I think I can enjoy horse riding, walking and fishing. They’ll make a change from sitting by the seaside and swimming.”

　He wrote to the farmer. In the letter he said that he would like to spend all of July there. Then on the first of July, he left for West Hill Farm.

　But four days later, he returned home.

　“What was wrong with West Hill Farm?” his best friend, Ed, asked him. “Didn’t you enjoy country life?”

　“Country life was very good,” Henry said. “But there was another problem.”

　“Oh. What?”

　“Well,” he said, “the first day I was there a sheep died, and we had roast mutton for dinner.”

　“What's wrong with that?” Ed asked. “Fresh meat is the best.”

　“I know, but on the second day a cow died, and we had roast beef for dinner.”

　“Lucky you!”

　“You don't understand,” Henry said. “On the third day a pig died and we had roast pork for dinner.”

　“A different meat every day,” Ed said loudly, “ and you are complaining!”

　“Let me finish,” Henry said. “On the fourth day the farmer died, and I didn't dare (敢)stay for dinner!”
