篇7:THAT用法总结

“that”在英文中是一个使用频率很高的单词。它有四种词性,并且句法及语法功能纷繁复杂。同学们如果不能熟练掌握其用法,很可能会形成英语学习的一种障碍,从而影响其学习兴趣和效率。现将that的用法总结归纳如下:

第一、that 用作形容词(后接复数名词时用those)。

它用来指已被提到的人或物;也可表对比,指两个中较远的那个。

what about that book you borrowed from me last month?

请注意,that 有时候在句子中具有喜欢或轻蔑等感情色彩。

that little son of his 他那个小宝贝儿子

that george!乔治那家伙!(含有轻蔑语气)

第二、that 用作代词。

1. that 用作指示代词(复数形式是those),其指代意义同形容词用法,同时它还可以用作定语从句中的先行词;还可为了避免重复,代替前述名词。

that is what he told me.

what is that (which) you have got in your hand?

the price of rice is higher than that of flour.

2. that 用作关系代词,引导限制性定语从句。先行词可人可物,用法相当于who或which。(但是在下列情况下多用that:先行词既有人又有物时;先行词有形容词最高级、序数词、不定代词、very,only等修饰时;先行词是不定代词时)

he talked about the teachers and schools that he had visited.

i think it one of the most wonderful films that the film company has ever produced.

请注意,that 在定语从句中作宾语时通常可省略。

④引导同位语从句。

引导同位语从句的that和引导定语从句的that是不同的。前者只起语法作用,在从句中不作任何成分;而后者在定语从句中作主语、宾语或表语。举例说明:

the news that he resigned from office surprised us.

the idea that he holds is very common nowadays on campus.
