Last week Lu visited England. He stayed with my grandmother. He said it was a strange visit. “I don’t understand, but I  16 your grandmother a lot. When I arrived, I gave her a   17  from Suzhou. She looked in it and asked me to take it back. Then I saw a red spider(蜘蛛) on the table so I killed it for her and she seemed very   18  . Do English people like spiders?”
“Later we went shopping. Someone was painting a shop   19 , so there was a ladder. Grandmother  20 me walking under it and said I must walk around it. I liked the shops and bought a smart   21 for my father and some new shoes for myself. When we got back, I put the shoes on the table and opened the umbrella to wonder   22 it was all right. Your grandmother came in and   23  !”
“Then I broke a small   24 in the bathroom. Your grandmother’s face went white. I felt very sorry. When I left I gave   25 grandmother some flowers. She counted and there were 13. She   26 it. I think she was happy I was going.”
I   27 to Lu, “My grandmother follows the old customs(习俗). You must not give someone an empty purse   28 they will have no money. You must not kill a “money spider”  or the same will happen. It is very unlucky to walk under a ladder and to put new shoes on the table. A(n)  29 umbrella in a house means someone will die. Breaking a mirror brings seven years’ bad luck, and 13 is   30 a very unlucky number. You were really making my grandmother very afraid. ”

Our nearest neighbor is the moon. In the sky,  the moon and the sun seem to be of the same size because the moon is much nearer.
The moon makes the tides—the changes in the level of the sea. The moon and the sun together pull the sea. In some parts of the world,  the difference between * high tide’ (when the sea is very near to the land) and ’ low tide’ (when the sea is far away from the land) is very big. This is very important for ships.
The moon is very different from the Earth. Gravity on the moon is six times weaker than that on the Earth. There isn’t any air. During the day,  it is very,  very hot but at night it is very,  very cold. Nothing can live on the moon.
If the moon goes between the Earth and the sun,  we have an eclipse of the sun(日食) . The moon stops the light from the sun and we have night in the day.
If the Earth goes between the moon and the sun,  we have an eclipse of the moon. The moon goes into the shadow( 影子) of the Earth and it disappears for a few minutes.
