[小学]语法填空专项训练---时态语态
![[小学]语法填空专项训练---时态语态](https://img.taocdn.com/s3/m/9e69b8a064ce0508763231126edb6f1aff007176.png)
语法填空专项训练---时态语态时态和语态是广东高考语法填空中的必考点，每年必考1题。
究竟考些什么内容？现将考点简述如下：1. 时态。
时态是英语谓语动词的一种形式，表示动作发生的时间和所处的状态。
英语中的时态是通过动词形式本身的变化来实现的。
英语中常用的时态有16种，但高考考试说明中规定要掌握的有十种：注：(1)表示将来还有多种形式，如：“be going to +动词原形”“be to+动词原形”“ be about to+动词原形”等。
在飞机、火车等时刻表中规定的事情，或在时间状语从句或条件状语从句中，要用一般现在时表示将来；表示计划好的活动，还常用现在进行时表示。
(2)现在进行时与always，continually，constantly等连用，表示说话人的某种情感，如赞扬，遗憾，讨厌或不满等。
如：He is always helping others.他总是帮助别人。
(赞扬)2. 语态。
语态有两种：主动语态和被动语态。
主语是动作的发出者为主动语态；主语是动作的接受者为被动语态。
被动语态由“be+过去分词”构成，不同时态的被动语态的形式由be 来体现，如一般过去时的被动语态就是“was/were+过去分词”，一般将来时的被动语态就是“will be +过去分词”。
解题技巧在广东高考英语语法填空中，一般有一空是考查谓语动词的时态，同时有一空是考查非谓语动词，因此，首先要判断括号中所给动词是谓语动词还是非谓语动词；若是谓语动词，一是根据主语与谓语动词的关系判断用主动语态还是用被动语态，二是根据具体的语境来判断用哪一种时态，进而确定所填动词的形式。
例1：This proverb is saying we have to let things go in their natural course. Being too anxious to help an event develop often 40 (result) in the contrary to our intention. (2008广东)分析：因句中Being too anxious to help an event develop是动名词短语作主语，括号中的result 应当为谓语动词；主语与谓语动词是主动关系，再说短语动词result in本身是不能用于被动语态的，故用主动语态；根据语境，这段话是拔苗助长这个成语故事所说明的道理，“我们必须让事物沿着它们的自然进程发展。
