1 . Why do you think people who live in some hot countries eat very spicy(辛辣的)food? Is it because the spices make the food taste better? Is it just because their parents and grandparents and great-grandparents liked hot food，or is there some connection between spices and healthy food?

4 . 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 (消失), 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, you can see the letter again. Now do the same experiment with your left eye closed, you’ll find the letter R disappearing.
