1、在复合句中,由一个句子充当宾语,这个句子叫做宾语从句。宾语从句主要有三种类型,分别是that引导的宾语从句、if或whether引导的宾从、连接代词和连接副词引导的宾语从句。 常见的宾语从句引导词:that、if、whether、what、who、where、why和how。
Eg. I am sad that you refused me. 我很难过你拒绝了我。
2、定语从句在中考和高考中出现的频率都非常高。在复合句中,修饰名词或代词的从句叫定语从句。被修饰的名词或代词叫先行词。定语从句一般放在先行词的后面。常见的关系代词包括that,which,who(宾格whom,所有格whose),as 等,关系副词包括where,when,why等。
Eg. Lily likes music that is quiet and gentle. 玛丽喜欢轻柔的音乐。
