2021小升初英语总复习第九讲介词知识点讲解+练习
第九讲：介词一、【考点解读】介词是一种用来表示词与词、词与句之间的关系的虚词，在句子中不能单独作成分。
介词后面一般有名词代词或相当于名词的其他词类，短语或从句作它的宾语。
介词和它的宾语构成介词词组，在句中作状语、表语、补语或介词宾语。
介词可以分为时间介词、地点介词、方式介词、原因介词和其他介词。
介词是英语中最活跃的词类之一，特别是一些常用介词的搭配力特别强，可以用来表示各种不同的意思。

一般过去时态和现在完成时态的区别练习题
一般过去时态和现在完成时态的区别练习题1）一般过去时态表示过去某时发生的动作或单纯叙述过去的事情，强调动作；现在完成时态中动作为过去发生的，强调过去的事情对现在的影响，强调的是影响。
如:I saw this film yesterday. （强调看的动作发生过了）I have already seen this film.（强调对现在的影响，电影的内容已经知了）I haven’t finished my work yet. (强调对现在的影响，还有工作要做，不能去玩) When did you finish your homework? (询问过去的动作所发生的时间，与现在无关)2）一般过去时态表示动作在过去已经停止；现在完成时态表示过去开始的动作一直延续到现在。
如：Ann visited her uncle last weekend.(visit这个动作在过去已经停止) They have lived here since 1983.(live here 这个动作从1983年开始，一直延续到现在)3）一般过去时态常用非延续性动词，如borrow, buy, come, go, leave, start, die, finish, become等。
现在完成时态可表示持续到现在的动作或状态，与时间段连用时动词一般是延续性的，如keep, have, live, teach, learn, work, study, know, be等。
如：He joined the League three years ago .(join是短暂动词）He has been in the League for three years.（be in表状态，在团内的状态可延续）He has been a League member for three years. （是团员的状态可延续）4）一般过去时态常与具体的时间状语连用，而现在完成时态通常与模糊的时间状语连用，或无时间状语。

since,for 和 ago 的用法区别习题(答案及解析)
Since 和 for 都可用于完成时，而 ago 只能用于过去时，其中 since 后面连接的是一个时间点，可以是一个具体的年月日或事件，而 for 后面连接的是一个时间段，不一定是确定的时间，但必须是一段时间。
从词性和连接时间来看，since 可以是介词、连词或副词，而 for 只是介词，ago 是副词，因此答题的关键是从时态和词性出发。
一、用 since，for 或 ago 完成下列的句子1、Claire is in Poland now. She has been there _____ two weeks.2、Claire has been in Poland _____ May and she is still there.3、Claire went to Poland two weeks _____.4、Matthew is studying in his room.
