几个看不懂结构的英语句子
1.Your brain sends chemicals around your body that are good for you.
这里around your body和 that are good for you个是什么成分?修饰什么或者有什么用?
2.Whatever the reason,research shows that in the end,the English saying"Laughter is the best medicine"may be true after all.
在这里in the end和那个逗号是干什么的?after all不是毕竟的意思是什么?
3.He made an advertisement for Pepsi in the 1980s that became very poplular.
在这里that became very poplular是定语从句么?
4.He is my favorite stand-up comedian,and I enjot watching him on TV and in films.
在这里
comedian后面的那个逗号有什么用?我觉得以前的这种复合句没有逗号的,直接接and的啊

Answer 1

1. around your body作状语,说明chemicals作用的位置.that引导同位语从句.
2.in the end是时间状语,“最终,调查研究表明了它”.after all在这里是强调为几经周折后的结果.
3.不是. 定语从句是必须有先行词的,如果现行此时前面的一整句,那么他就是非限制性定语从句,而非限制性定语从句是绝对不可能用that引导的~!这是一个同位语从句.
4.这不是复合句,而是两个简单句用逗号和连词（and）连接的并列句.
