since when说起,浅谈几个特殊的定语从句

    定语从句是高考的热点之一,在每年的高考英语试题中,几乎所以省份都会考查一处定语从句。而且,最近几年还考到了比较特殊的用法。请看典型试题:

【典型例题】

1. He was educated at a local grammar school, ______ he went on to Cambridge.

    A. from which    B. after that    C. after which    D. from this

2. The book was written in 1946, ______ the education system has witnessed great changes.

    A. when    B. during which    C. since then    D. since when

【典例分析】

1. 句意:他在当地一所文法学校上学,之后他便去了剑桥。根据句意可排除AD两项;after that意为“然后,之后”,但不能引导一个定语从句,因此B项也被排除;after which相当于and after that,不但符合语境,而且能引导定语从句,故答案为C

2. 句意:该书写于1946年,从那以后教育制度已经历了巨大变化。根据从句中的现在完成时态和句意,我们可排除AB两项;短语since then意为“从那以后”,但不能引导一个定语从句,因此也排除了C项;故此处应选D项,since when相当于and since then,它能引导一个定语从句。

【同类例句】

除了上述例题外,我们还回见到下面的例子:

1. At home, he never seems to have time until after 10:30 pm, by which time his children have gone to bed.

= At home, he never seems to have time until after 10:30 pm, and by that time his children have gone to bed.

在家里,他好像十点半之后才有空,到那时孩子们已上床睡觉了。

2. We were next-door neighbors for three years, during which time we met only twice.

= We were next-door neighbors for three years, and during this/that time we met only twice.

我们做了三年隔壁邻居,在此期间我们只见过两次面。

3. It occurred to him that it would save a lot of trouble to destroy the advertisement, in which case, he would have to explain to Peter.

=It occurred to him that it would save a lot of trouble to destroy the advertisement, but in that case, he would have to explain to Peter.

他曾想到过,撤销广告会避免很多麻烦;但是如果那样的话,他必须向皮特做出解释。

4. I was told my work was unsatisfactory, at which point I submitted my resignation.

= I was told my work was unsatisfactory, and at this/that point I submitted my resignation.

被告知我的工作不能令人满意,闻讯后我便递交了辞呈。

5. He is studying economics, which knowledge is pretty important today.

= He is studying economics, and this knowledge is pretty important today.

他在学习经济学,这门知识在当今非常重要。

6. He stood by the window, from where he could see what was happening outside.

= He stood by the window, and from there he could see what was happening outside.

他站在窗子旁边,从那儿他能看到外面发生的一切。

【小结点拨】

    根据上面的例句,我们不妨做出如下总结:①带有this, that的短语,引导定语从句时,要将this, that变为which;②带有here, there的短语,引导定语从句时,要将here, there变为where;③带有then, now的短语,引导定语从句时,要将then, now变为when;④带有one's的短语,引导定语从句时,要将one's变为whose
