托福写作之介词的使用方法详解

2014-12-08 15:30:22来源:网络

等常见用法一般也不会出现错误。但是对于与动词搭配的介词to就会经常犯错:

  如:

  More and more students have taken to depend on their parents to make decision for them.

  这里的‘take to’ means ‘to begin to do sth as a habit’其中‘to’为介词,所以后面只能接名词或相当于名词的词,如动名词。所以黑体处应改为“depending on”。“take to”的另一个常用用法也需要牢记:

  He hasn’t taken to his new school. (这里‘take to’ means ‘to start liking sb or sth’)

  Prefer A to B中的“to”也是介词,会有prefer doing sth to doing sth/ prefer sth to sthelse,“prefer to do sth rather than do sth”中的“to”可是真正的不定式符号。

  类似的常用用法请同学们牢记:

  Be used to doing

  Be accustomed to doing

  See to doing

  Adapt to doing

  Adjust to doing

  prefer doing sth. to doing sth.

  等等,托福写作请注意平时仔细积累。

  assume及claim使用不够准确

  我们知道, think, assume, claim是议论文中常用引出观点的动词。在实际作文中,同学们往往认为几个词的意思是一样的,完全可以代换,所以拿过来就用。甚至还有同学把consider也拿过来与之混用。我们首先还是从定义来看这几个词的不同:

  Think: to have opinion or belief about sth.

  翻译为“认为”,通常接宾语从句来表达比较确定的观点。

  Assume: to think or accept that sth is true but without having proof of it.

  翻译为“假设、假定”,是否有事实依据是不确定的。

  Claim: to say sth is true although it has not been proved and other people may not believeit.

  翻译为“声称”,用这个词往往意味着不赞同紧跟其后的观点,所以很少用作‘I claim that…
