【考前冲刺】高考英语专题课件：110定语从句(安徽专用)(100张).ppt

单项填空(十)——省略法 高考在命题时，通常在题干中加入一些非关键信息，就是去掉它们也不影响对句意的理解，并且句式结构更简洁明了，有助于对题目的理解和最佳答案的选择。对于这类题目，解题时就要采用省略法，省略那些不必要的内容，如插入语，过渡语，解释性内容等。 1. The scientist made several discoveries, _______. A. which we think are important B. which we think that is important C. we think which are important D. which we think is important 【解析】选A。考查非限定性定语从句。句意：这个科学家有好几个发现，我们认为这些发现都很重要。we think为插入语；从句的谓语动词应与先行词discoveries一致。 2. He managed to achieve his goal in a way ________. A. what you thought was impossible B. that you thought was impossible C. you thought was impossible D. in which you thought was impossible 【解析】选B。考查定语从句。句意：他成功地用一种你认为不可能的方式实现了他的目标。根据句意，此处为定语从句，排除A；you thought为插入语，was impossible缺主语，排除D；主语不能省略，排除C。 (2)from where为“介词＋关系副词”结构，也可以引导定语从句。 We stood at the top of the hill, from where we can see the town. 我们站在山顶，从那里我们能看到那个小镇。 (3)像listen to, look at, depend on, pay attention to, take care of等固定动词短语，在定语从句中一般不宜将介词与动词分开。 This is the boy whom she has taken care of. 这就是她照看的那个男孩。 (4)whose+名词=the+名词+of which/whom =of which/whom+the+名词 【易混点拨】 1. 当“介词+which”在定语从句中作时间、地点和原因状语时，可以用相应的关系副词when, where和why来替换。 2. when根据情况可以等于in which, at which, on which等。 3. where根据情况可以等于in which, at which, on which等。 四、限定性定语从句与非限定性定语从句 1. 二者区别 (1)限定性定语从句：从句与主句关系密切，去掉从句，主句意义不完整，甚至不合逻辑。 I was the only person in our office that was invited. (去掉定语从句，意思就不完整) 我是我们办公室里惟一一个受到邀请的人。 (2)非限定性定语从句：从句与先行词关系不密切，去掉定语从句，意思仍然完整。形式上用逗号隔开，不能用that引导。 Tom’s father, who is over sixty, still works hard day and night. (who引导非限定性定语从句，整个句子可分成两句来翻译) 汤姆的父亲已经60多岁了，但仍然还是日夜辛苦地工作。 2. as引导定语从句时的用法 (1)as引导限定性定语从句通常用于the same . . . as, such . . . as结构中。 I want the same shirt as my friend’s. 我想要一件跟我朋友的一样的衬衫。 Such machines as are used in our workshop are made in China. 我们车间使用的这种机器是中国制造的。 (2)as引导非限定性定语从句既可放在主句之前，也可放在主句之后，用来修饰整个句子。通常用下列句型：as is known to all, as is said, as is reported, as is announced, as we all know, as I expect(ed)等。 As I expected, he got the first place again in this mid-term examination. 正如我所预料的那样，他在这次期中考试中又获得了第一名
