怎样才能推测出英语四六级的生词的含义

如何推测出大学英语四六级考试生词意思，英语四六级考试涉及的词汇比较多，大家需要记住大量词汇及语法，很难说都或多或少都会遇到生僻词，有些可以忽略，但有些很关键，英语四六级考试还是比较考验实力的，当然技巧很是很重要的，那么如何推测出四六级考试遇到的生词意思呢？

一、利用所出现生词的上下文与其意义上的联系或下文进一步的叙述，猜测词义。

例：

The female mosquito is a vampire and lives on blood.

如不知道vampire的词义，从下文lives on blood(靠吸血而生存)则可得知其词义为吸血昆虫。

例：

The old man put on his spectacles and began to read.

如不知道spectacles的词义，从下文戴上spectacles后开始阅读可以猜得其词义透视。

二、利用文中的举例猜测词义。

例：

Some artists plan their paintings around geometric forms like squares, circles and triangles.

如不知道geometric forms的意思，可从文中所列举的三角形，正方形、圆形来猜得其意义为几何图形。

Today young couples who are just starting their households often spend lots of their money on appliances for instance, washing machines, refrigerators and color televisions.

如不知道appliances的意思，从文中的举例washing-machines(洗衣机)，refrigerator(冰箱)，televisions(电视机)可以猜得该词的意思为家用电器。

三、利用文中说明词义的同位词或定语等，猜测词义。

例：

The invention of snorkel, a long air tube that reaches up to the surface, has made it possible for submarines(潜艇) to use their diesel engine even when they are submerged.

句中snorkel一词的意思，可通过其同位语a long air tube that reaches up to the surface来猜得。由此我们可确定该词义为通气管。

例：

The type of meter is called multimeter, which is used to measure electricity.通过定语从句which is used to measure electricity(用来测量电的)，我们可将multimeter的词义确定为万用表。

例：

They will be on the night shift ― from midnight to 6 a. m. ― next week.

由破折号之间的解释内容，我们可以了解到night shift意思为夜班。

四、利用文章中所出现的、与某生词或词组意思相反的内容，猜测词义。

例：

American businessmen expect employees to be punctual. They do not expect that the workers will come late.

文中be punctual的意思，可理解为not come late，即准时，不迟到。

例：

Unlike her gregarious sister, Jane is a shy person, who does not like to go to parties, or to make new friends.

根据文中unlike的意思，可将gregarious理解为与文中a shy person who does not like to go to parties, or to make new friends.相反的意思，即：表示好交际的。

五、利用文章中用不同的话对同一概念的解释，猜测词义。

例：

Should the government regulate the cost of resources such as oil and gas? Some people do not believe that government control is the solution to the problem of the rising cost of fuel.

文中regulate的词义可猜测为与government control的意思相近。

例：

One of the predominant concerns today is the future of our natural resources. This issue is of greatest importance because it is becoming clear to many people that our present resources will not last forever.

文中predominant的词义可猜测为具有与of greatest importance相近的意思。

例：

Cleaning up waterways is an enormous task. The job is so large, in fact, that the government may not be able to save some of the rivers and lakes which have been polluted.

文中enormous的词义可猜测为与so large的意思相近。

六、利用基本的构词方法，猜测词义。

例：

They overestimate the interviewee's ability and asked him many difficult questions.

在overestimate词中over-是前缀，意为过分。所以overestimate的词义可以猜测为过高估计的意思。

例：

We were told that our's was the most spacious room in the hotel. That was why we had to pay so much for it.

Spacious是由词根space(空间) ious(形容词后缀)构成。由此我们可以猜得其大概意思为有空间的，宽敞的。

但是需要指出的是，不要花费太多的时间去试图猜出所有生词确切的意思，因为有的生词只能猜出大概的意思，有的生词则根本无法猜出其意思。一般来说碰到一、两个不会的词，无关紧要。重要的是要弄懂整篇文章表达了什么思想。
