典型例題
1.閱讀分析點撥
Alice suddenly called on Betty on Saturday. 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 根據“Alice suddenly called on Betty”可以斷定 Alice不是被邀請的，這是做1.1題的，根據句尾“on the cat-trap”我們可以看出奶酪不適合，所以最后關鍵回答可以幫助你作出判斷2、3、5、7題.
2.當你離開的時候，所有的燈都應關掉.
誤：When you leave, all the light should close.
正：When you leave all the light should be turned off.
解析 關燈應用 turn off不能用close，并且用被動語態(tài).
3. 紐約離北京有14，8000公里
誤：New York is 14，8000 Kilometres far away from Beijing.
正：New York is 148000 away from Beijing.
解析 與具體的距離連用時，不能用 far from.如 5公里，只能說 5 kilometers away here.
4.在老師的幫助下，他很快完成作業(yè)
誤：Under the teacher’s help, he finished the homework quickly.
正：With the teacher’s help, he finished to homework quickly.
解析 在某人的幫助下用 with one’s help， under則表示具體的方位如 under the tree under the desk.
5.In the library.我認為他們中的任何一個都沒趣
誤：I think any of them isn’t interesting.
正：I don’t think any of them is interesting.
解析 think，believe等在變否定句時，否定詞應放在句首.
