| 完形填空。 Mr and Mrs King have lived in our town for nearly twenty years. They have a book shop by the bus station. They're polite to everyone and have a lot of friends. They often 1 the poor students and sell them some books cheaply. So there're many young men in their shop. Of course people 2 them and their friends often visit them and 4 them. We can always hear their rooms are full of 3 and quarrel. It was a Friday evening. Mr and Mrs King were going to have a picnic on the island the next 5 . It was a little far from our town. So they had to 6 earlier than usual to catch a six o'clock train. After 7 a few friends came to see them while they were cooking some food and drinks for the picnic. Mr King and his wife had to stop to receive them. They talked a lot and few of them looked at the 8 on the wall. It was late. Mr and Mrs King were anxious (焦急的) but they couldn't tell the visitors about it. Mrs King thought for a few minutes and had an idea. She said to her husband, "Oh, it's eleven o' clock! You'd better stop talking ,dear! Our guests are anxious to 9 !" Mr King heard this and stood up, then he said 10 to the visitors and they left soon. | ||||
