教学活动1. 时态和主谓一致的分析
1.The fog lifted while I __was driving______(drive)home and I saw the golden autumn leaves shining in the sunlight.
分析: 过去进行时 提示信息: 两个并列的句子中谓语动词的时态都是过去时。
2.A number of boys ____are_____(be) playing computer games in the internet bar, but I don't know what the exact number___is______(be).
分析:
时态上根据后面句子中的don't know可知是一般现在时。
主谓一致上:A number of boys 大量的男孩 复数概念 所以是复数形式 the number 数量 不可数 所以是单数
3.By the end of this month he ___will have been trainning/will have trained_____(train) horses for twenty years.
分析:By the end of this month是一般将来时的时间状语;for twenty years是现在完成时的时间状语。所以结合起来就要用将来时的完成态形式。
4.The park, as well as the surrounding hills, where they once had a good time, ___has_____(have) changed a lot.
分析:as well as the surrounding hills, where they once had a good time 是插入成分。句子的主干是The park___has_____(have) changed a lot.主语The park是单数,所以谓语动词用单数形式。
5.To her disappointment, what she had devoted herself to ____resulted____(result) in nothing but failure.
分析:what she had devoted herself to是主语从句, 根据从句中的谓语动词的时态(过去完成时)可以确定主句中的谓语动词的时态是过去时。
6.The university estimates that living expenses for international students_____are________(be) around $8,450 a year, which ____is_____(be) a burden for some of them.
分析: 第一空的主语是 living expenses是复数概念,所以用are; 第二空的主语是which指代$8450,是单数概念,所以用is.
7.Walmart, which is one of largest American supermarket chains,____keeps______(keep) some of its stores open 24 hours on Monday through Sataudays.
分析:根据从句中谓语动词的时态可以确定,主句中谓语动词的时态是一般现在时, 主语Walmart是单数概念,所以谓语动词填单数形式。
教学活动2.语态和主谓一致的分析
1.Half of the work assigned by our department manager _has been completed_____(complete) by now.
分析:
句子层级一:Half of the work _has been completed_____(complete) by now.
句子层级二: assigned by our department manager(过去分词短语作后置定语)
句子中的主语是Half of the work, 不可数,所以主谓一致上是单数。
句子中的时间状语by now, 现在完成时的标志。
语态上,工作是被完成,所以是被动态。
2.His newly written novel ___had been translated_____________( translate) into more th
