  动词不定式和动名词在TOEEL考试中不算活跃的考题,但出题频率比较稳定,即不频繁,亦无间断。命题焦占主要集中在动词不定式和动名词的基本功能及正确形式,即(1)不定式to后面接原形动词,(2)动名词具有动词和名词两重功能,介词后面的动词必须以动名词形式出现。不定式和动名词常考题型 

1. 动词不定式to后面接原形动词

  (1) Astronauts circling the Earth may get to seen sixteen sunrises and sixteen sunsets every day. (93.8) 
  [答案] C 动词不定型式的标志to后面应接动词原形see。 
  (2) Using their bills as needles, tailorbirds sew large leaves together with plant fiber to forming their nests. (90.10) 
  [答案] D to forming应改为to form正确的不定式形式。 
  (3) The poetry of e.e cummings illustrates the way in which some poets bend graminastical rules as they strive to expression their insights. (91.10) 
  [答案] D动词不定式to后面只能接原形动词,不能接名词。 
  (4) The dromedary camel is raised especially to racing. (91.1) 
  [答案] D这是一个非常简单的动词不定式错误形式的考题。Recing应改为race,与to组成不定式。 

2. 动词不定式作目的状语
  解题要点 不定式结构在句中可以作多种成分,目的状语则是TOEEL常考到的形式。动词不定型式作目的状语的命题主要分布在structure (1-15题)中。

  (A) generating

  (A) Creates 
  (B) Created 
  (C) The creating of 
  (D) To create (92.10) 
  [答案] D 这是典型的不定式作目的状语的句子。目的状语放在句首是表示强调。 
  (3) ------- time and labor, cartoonists generally draw the hands of their characters with only three fingers and a thumb. 
  (A) Saved 
  (B) Saves 
  (C) To save 
  (D) The saving (91.5) 
  [答案] C 此句与上面例题结构相同。不定式作目的状语,且放在句首表示强调。 

3. 动名词的正确用法
  解题要点有关名词的考题并不很多,但有一个常出现的题型;介词后面的动词一定要用动名词形式,作介词的宾语。 
  全真例题分析 
  (1) Microwave cooking can be accureately described as the first absolutely new method of prepare food since the discovery of fire (94.1) 
  [答案] C 介词of后面应接动名词形式,即of preparing。 
  (2) Most crickets have two pairs of fally developed wings, and mascular hind legs for iump. (94.1) 
  [答案] D 动名原形jamp位于介词for后面,故应改为动句词jamping。 
  (3) Because it is a healthful way to exercise derobic dancing is considered an excellent method for release tension. (93.1) 
  [答案] D 动名词原形release位于介词for后面,故应改为动名词releasing。
