牛津版英语九年级上unit3知识点牛津版英语九年级上 Unit 3 知识点Unit 3 是九年级上册的第三个单元，主要讲述了介词、不定代词以及情态动词的用法。

这些知识点在英语学习中非常重要，对于准确运用语言、更好地表达自己的意思起着关键作用。

1. 介词介词是连接词或短语之间关系的词语，常常用于描述时间、地点、方向和方式等。

在英语中，常见的介词有 in, on, at, with, of, from等等。

这些介词的使用需要根据具体的语境来决定。

比如，“in”用于表示时间、地点或状态；“on”用于表示表面或接触点；“at”用于表示具体的时间或地点等。

2. 不定代词不定代词是用来指代不明确或不确定的人或物的代词。

常见的不定代词有 someone, anyone, nobody, everybody, something, anything, nothing等等。

不定代词可以在句子中作主语、宾语或补语。

）3. 情态动词情态动词用于表示说话人的态度、情感或能力。

常见的情态动词包括：can, could, may, might, must, shall, should, will, would等等。

情态动词在句子中常常与动词原形连用，表示能力、可能性、必要性、意愿等。
