题目内容

9．The law of gravitywas discovered （discover） by Isaac Newton about 350years ago．

分析万有引力定律大约在350年前由艾萨克牛顿发现的．

解答答案：was discovered．主语是The law of gravity是动词discover"发现"的承受者，构成被动关系，时间状语about 350years ago表示350年前，故用一般过去时的被动语态was/were+过去分词，主语是三单，故was，discover的过去分词discovered，故答案是was discovered．

点评一般过去时的被动语态was/were+过去分词的呈现，各种时态的被动语态的构成要理解记忆．

Mary can hardly speak Chinese，canshe？

Tom’s father has a big farm. On New Year’s Day, his father asked him, “Could you work on the farm when you’re free this year, Tom?”

“Farming is not my work, Dad. I have much school work to do,” Tom wasn’t glad at it.

“If you help me work on the farm, I will give you anything you want.”

“OK,” Tom agreed happily.

So Tom gets up early and works hard on the farm in his free time this year, just like other farmers. His wheat grows very well.

Time flies. Today is the last day of the year, December 31st. The father is talking with his son.

“I’m happy to see you work hard on the farm. Tom, now tell me what you want as the gift(礼物).”

Tom shows his father a big piece of bread. He makes it with the wheat on his farm. “I have already gotten your gift, Dad. You’re trying to give me a lesson—- no pain, no gain.
