浅谈先行词的前面为什么要加介词

首先看一个定语从句的例子,请看下面第一句。

  ①He grew up in the house [in where] he still lives with his wife.

  ②He grew up in the house [where] he still lives [in the house] with his wife.

  ③他在这所房子里长大,他和他妻子现在仍然住在这所房子里。

  我们可以看到,在先行词where的前面,有一个介词in。假如我们不要这个in,那么这句话应当改写成上面第二句,而第二句有一个明显的毛病,那就是the house出现了两次,一次出现在主句中,一次出现在从句中,而这种同一成分在同一句子中的多次重复,正是英语的大忌,所以我们必须将in转移到where的前面,从而将第二次出现的the house省略掉,并用where代替这个被省略掉的the house,您明白了吗?下面我再举三个类似的例子,请您自己分析一下,原理都一样,我就不罗嗦了。

  ①This is the book [by which] Newton"s calculus1 was introduced into China.

  ②This is the book [which] Newton"s calculus was introduced [by the book] into China.

  ③正是通过这本书,使牛顿的微积分介绍到中国来。

  ①Please contact your webmaster [from whom] you can obtain a new password.

  ②Please contact your webmaster [whom] you can obtain a new password [from your webmaster].

  ③请联系您的网络管理员,您可以从他那里获得一个新口令。

  ①This is the ruler [with that] you can draw a straight line.

  ②This is the ruler [that] you can draw a straight line [with the ruler].

  ③这就是那把尺子,您可以用它划一条直线。
