It seems to be strange to you that there is a blind spot (盲點)on the eyes. Here is an interesting experiment (實驗) 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.
1.The writer of the passage thinks that ________ there is a blind spot on the eyes.
A．few people know
B．no one knows
C．most people know
D．a(chǎn)ll the people know

3.You fail to see the letter L in the experiment because ________.

Dear Annie,
I have never written a letter to a newspaper before, I have just never felt the need to do such a thing. I have always felt I was quite able to do everything by myself. But now I know I was wrong.
Sometimes you really need help in life, I guess. And that’s why I’m writing this letter to you.
I have a happy family. I love my children and they love me . I’m a mother of three children. I know well how to bring up (帶大)children, and two of them are already over twenty, so it is nothing new for me.
But now I have a serious problem: the Internet problem. My little son is just sixteen, and I feel he should do a lot of homework now , but he doesn’t seem to be interested in it . He can happily spend six or eight hours at a time on the Internet every day , He chats with people that he has never met before , but speaks little to us .He does lots of useless things on the Internet. And he sees red if you ask him to do his homework.
I just want him to be a good student . Now he seldom does his lessons at home. I’m afraid he will drop behind in his class soon. His father is a doctor , a very kind man . He never seems to be afraid of his father.
What can I do ?And don’t tell to talk to him. We’ve tried that and it didn’t work. But this is really a big problem in our family. I have tried everything I can think of . I
wonder how the Internet is so attractive(有吸引力的).You’re my last hope. Please tell me what I can do!
Yours,
Ellen Smith
