英语语法词汇详解because与because of的区别because 连接词，（引导状语从句和表语从句），因为【辨析1】because与so先来看几个例句，正：Because it was raining, we stayed at home.正：It was raining, so we stayed at home.误：Because it was raining, so we stayed at home.because 为从句的引导词，引导的句子是从句，有从句的句子叫复合句。so 是并列连词，连接前后两个句子，构成一个并列句。一个句子要么是并列句，要么是复合句，不允许既是并列句又是复合句，所以because 和so 不可能在同一句。【辨析2】because与because of两者都表示因为，区别如下because 后加上句子而because of 后加上名词，或短语He walked slowly because theres something wrong with his leg.He walked slowly because of his bad leg.【辨析3】because, as, for, since这几个词都是表示“原因”的连词，语气由强至弱依次为：becausesinceasfor;其中because, since, as均为从属连词，引导原因状语从句；而for 是并列连词，引导并列句。【小试牛刀】I didnt go to the mountains _ the bad weather.A. so B. because of C. because D. but解析：选Bbeat bit动词，击败、战胜【辨析1】win和beat二者作赢、战胜讲时，其区别主要在于宾语的不同：1）充当win 的宾语的是比赛、战争、奖品、金钱等名词，即race，match，game， competition，war，prize 之类的词；表示在某项活动或比赛中获胜。例如：Who won the game?2）充当beat的宾语的则是比赛、竞争的对手，即指人或球队的名词或代词。例如Our class beat Class One in the table tennis match yesterday.（助记点：win+比赛/活动， beat+对手） （连续地）敲打【辨析2】beat与hit两者都有“打、击”的意思，但用法不完全相同。beat表示用力反复地打。例如She was beating the drums.hit表示瞬间动作，强调“打中或击中”这一结果，或强调敲打、打击对象某一点，只作及物动词用。例如She hit him on the head with a book.（心脏等）跳动（音乐）节拍【巩固练习】They didnt _ the basketball match.
