It seems to be strange to you that 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 eyes. 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】The writer of the passage thinks that ________ there is a blind spot on the eyes.

This happened to me at the age of twelve. It seems like a long time to remember the name of the old lady. Yet it keeps in my  35 that she taught me a lesson in tolerance(宽容) which I shall never forget.
On a winter afternoon, a friend and I were  36 stones onto the roof of the old lady’s house. I found myself a perfectly smooth stone and threw it out. The stone was too smooth, however, so it slipped(滑) from my hands and  37  straight not for the roof but for a small window on the old lady’s back porch(门廊). At the sound of broken   38 , we knew we were in trouble and ran away.
I was too scared(胆怯) about getting caught by the old lady that first night. However, a few days later, when I was sure that I hadn’t been   39 , I started to feel guilty(有罪的) for what I had done. She  40 greeted me with a smile each day when I gave her the newspaper, but I was no longer able to act comfortably.
I made up my mind to  41 for her window with my paper delivery(发送) money I collected. I put the money in an envelope with a note explaining I was  42  for breaking her window and hoped that the seven dollars would cover the cost for repairing it.
I waited  43 it was dark, snuck(悄悄地走) up to the old lady’s house and put the letter I didn’t sign in her door. Once again, I could have the freedom of lookingstraight  44 the old lady’s kind eyes.
The next day, I handed the old lady her paper and was able to return the warm smile that I was  45 from her. She thanked me and gave me a bag of cookies.
Reaching for the cookies, I  46 an envelope and pulled it out of the bag. When I opened the envelope, I was surprised to see the seven dollars and a short note that said, “I’m proud of you!”

It seems to be strange to you that 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 eyes. 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.
