attributive clauses , the past perfect continuous tense and the present participles .
teaching procedures :
step 1 疑难透析
1. what had he been doing before the earthquake ?
过去完成进行时表示在过去一个时间点以前一直进行的动作; 而现在完成进行时则表示从过去一个时间点开始一直进行的动作。例如:
i had been doing my homework before you came .
i have been doing my homework since i came back home .
注意 完成进行时都是强调动作的延续, 故其中的动词必须是延续性的。
考查方向 现在与过去进行完成时的辨异。
【典型考题】 北京高考
three months went by before she knew it . 她还没有意识到三个月就过去了。
now that she is out of a job , lucy __________ going back to school , but she hasn’t decided yet .
a. had considered b. has been considering
c. considered d. is going to consider
【解析】由 she hasn’t decided yet 可知, lucy 还在考虑这件事情, 故用现在完成进行时, 表示动作还在继续。
【答案】b。
2. before she could move , she heard a loud noise .
before she could think twice , the water was upon her .
本句中，before 意为“还未来得及…就…”， 例如：
the telephone was hung up before i could answer it .
我还未来得及接电话, 电话就挂断了。
before 还可以表示“… 之后才…”, 例如:
he almost knocked me down before he saw me .他几乎把我撞倒才看到我。
before 还可用于 it was not long before …结构, 表示“不久以后”。在此句式中, it 表示时间, before 引起时间状语从句。若从句时态为将来时, 应用现在时表示。例如:
it was not long before the whole country rose up and drove the enemy out of their homeland . 不久以后, 全国人民奋起反抗, 把敌人赶出了他们的国土。
注意 before 用法很多, 在平时的学习中应特别注意。它既可用作连词又可用作介词, 应注意不同词性需要不同形式。
考查方向 before 与其他连词的意义辨析以及词义。
【典型考题】 北京高考
he made a mistake , but then he corrected the situation ___________ it got worse .
a. until b. when c. before d. as
【解析】根据句意“在形势变得糟糕之前纠正错误”可知, 答案应为 before 。
【答案】c。
3. who， whom ， that ，which 或 whose 引起的定语从句以及关系词与普通连词 and，but 等的用法区别。
who， whom， that， which 或 whose 为引起定语从句的关系代词，该使用哪一个由其在句中做的成分来决定：who， whom ，that ，which 在从句中作主语、宾语，而whose 在从句中作定语。
定语从句应为句子的一部分，故从句的前面不需要 and， but，so，or 等连词。而句中若有了这些连词，则不使用定语从句。这也就是何时使用关系词，何时使用普通代词的问题。例如：
he has three sons，and all of them are doctors .
或: he has three sons , all of whom are doctors .
考查方向 是选择关系词还是选择普通代词, 也就是选择含有定语从句的复合句还是并列句。
【典型考题】 辽宁高考
the factory produces half a million pairs of shoes every year, 80% __________ are sold abroad.
a. of which b. which of c. of them d. of that
【解析】80% 的前面没有连词, 故应用定语从句形式, 排除 c 项; 而 that 不能直接充当介词的宾语, d 项错误; 用 of which 表示从属关系“其中的”, 引导定语从句。
【答案】a。
4. 分词做状语
分词在句中做状语, 是一个重要的语法项目, 一定要把握。
若分词在句中做状语, 则由句子的主语来决定其形式。若主语与分词之间为主动关系, 则用现在分词; 为被动形式, 则用过去分词; 没有主动或被动关系, 则用状语从句或独立主格作状语。例如:
a storm broke out suddenly , sweeping away everything .
（a storm 与sweep away 之间为主动关系 ）
given more time , i will do it better . （i 与give 之间为被动关系）
it being a hot day , they went swimming . （独立主格）
辨析 分词做状语与并列谓语动词
若几个动词之间没有主次之分, 只有时间先后, 则用作并列谓语, 表示连续的动作, 最后两个动作之间加连词; 若动词之间有主次之分, 则次要动词用作分词作状语, 主要动词用作谓语, 且分词前不能加连词。
考查方向 在具体的语境中, 过去分词和现在分词的选择。
【典型考题】 广东高考
____________ the program, they have to stay there for another two weeks .
a. not completing b. not completed
c. not having completed d. having not completed
【解析】现在分词的完成式表示动作发生在谓语动词以前, 其否定形式要在分词的前面加not 。
【答案】c。
