从属连词是连接两个从句的词语,用于表达因果、条件、时间、让步等关系。从属连词中的从句是指被连接的从句,它不能独立成句,必须依附于另一个主句才能表达完整的意思。
从属连词中的从句又分为名词性从句和非名词性从句。名词性从句可以充当主语、宾语、表语等成分,例如:
- What she said is true. (她所说的是真的。)
- I know that he is honest. (我知道他是诚实的。)
- Her wish is that she could travel around the world. (她的愿望是能够周游世界。)
非名词性从句则分为形容词性从句、副词性从句和不完全从句。形容词性从句作定语,修饰名词或代词,例如:
- The book that I borrowed from the library is very interesting. (我从图书馆借来的那本书非常有趣。)
- The girl who is wearing a red dress is my sister. (穿红色衣服的那个女孩是我妹妹。)
副词性从句则作状语,修饰动词、形容词或副词等,例如:
- I will call you when I arrive in Shanghai. (我到上海后会给你打电话。)
- He speaks Chinese as if he were a native speaker. (他说中文就像是母语一样。)
不完全从句则是省略了从属连词的从句,例如:
- Although he is young, he is very talented. (尽管他年轻,但他非常有才华。)
- I will go to the party, if invited. (如果被邀请,我会去参加派对。)
