Betty said to her “I’m sorry, there isn’t anything for you to eat.” The boy of the family quickly left his room and returned with a piece of cheese in his hand. He gave it to Alice. Alice smiled and put the food into the match and said “Boy, you have better eyes than your mother.” Where did you find it? “On the rat – trap(捕鼠器)，” the boy answered. ( )1.Alice was invited. ( )2.Betty in fact had some food in the house. ( )3.The boy bought a piece of cheese for Alice. ( )4.Alice was very happy when the boy gave her cheese. ( )5.The boy had better eyes than her mother. ( )6.Betty didn’t want to give Alice something to eat. ( )7.The cheese was fit to eat. (答案：1.× 2.× 3.× 4.√ 5.× 6.× 7. ×) 分析 根据“Alice suddenly called on Betty”可以断定 Alice不是被邀请的，这是做1.1题的，根据句尾“on the cat—trap”我们可以看出奶酪不适合，所以最后关键回答可以帮助你作出判断2、3、5、7题. 2.当你离开的时候，所有的灯都应关掉. 误：When you leave, all the light should close. 正：When you leave all the light should be turned off. 解析 关灯应用 turn off不能用close，并且用被动语态. 3. 纽约离北京有14，8000公里 误：New York is 14，8000 Kilometres far away from Beijing. 正：New York is 148000 away from Beijing. 解析 与具体的距离连用时，不能用 far from.如 5公里，只能说 5 kilometers away here. 4.在老师的帮助下，他很快完成作业 误：Under the teacher’s help, he finished the homework quickly. 正：With the teacher’s help, he finished to homework quickly. 解析 在某人的帮助下用 with one’s help， under则表示具体的方位如 under the tree under the desk. 5.In the library.我认为他们中的任何一个都没趣 误：I think any of them isn’t interesting. 正：I don’t think any of them is interesting. 解析 think，believe等在变否定句时，否定词应放在句首. 【关于“Unit 12 Mainly revision”的常见问题】 常见问题1: Mainly revision 1 问题： This programme was sent to the USA __ China __ satellite． A．in; of B．of; in C．from; by D．by; from 解答: 分析这句话的意思是：这个节目通过卫星从中国送到了美国。介词from指“从，自……来”之意。by有“被，由，通过……方式”之意。注意介词的含义和搭配。 答案C 常见问题2: Mainly revision 2 问题： It must be on Channel 2, try that． I__ that．But I still can’t get anything． A．have tried B．tried C．try D．will try 解答: 分析“但我仍然什么信号都没收到”是try(尝试)的结果。现在完成时表示过去的动作对现在造成的影响或结果，由过去持续到现在，所以用try的完成时，表示已试过，并且有结果。注意分析题意。 答案A 常见问题3: Mainly revision 3 问题： What are you talking __?
