句型分析 1. Some people (S 主詞) believe (V動詞)that (O受詞) {the great amount of medical information avaible on the Internet can improve their health}-->修飾that 2. 接下來看子句 the great amount of medical information(子句內的S 主詞) avaible on the Internet can improve(子句內的V動詞) their health(子句內的O受詞) avaible on the Internet 都是用來修飾子句內的主詞the great amount of medical information PS以上為個人見解 如有錯誤煩請版上其他人幫忙解惑 謝謝^^
