Answer 1

1.句型：The reason why…… 意为“……的原因”
The reason why laughter can reduce pain 笑能够减少疼痛的原因
2.动词seem的用法：seems to be 意为“似乎是”
3.表语从句that it helps produce endorphins（内啡肽）in the brain
它（笑）能帮助产生大脑中的内啡肽
整合起来的句意就是：
笑能够减少疼痛的原因似乎是它能帮助产生大脑中的内啡肽.
答案看完了,就采纳一个呗!拜托啦!嘿嘿
百度答题人伤不起呀~%>_,3,The reason /（why laughter can reduce pain-是the reason 的同位语）到这里为止可看成是主语 /seems to be( that it helps to produce endorphinsin the brain整块做seem to be 里的that 从句.)-这是整个句子的谓语和宾语,2,主语 the reason
谓语 seems to be
宾语从句 that后面,1,句子主干的主语是The reason，谓语seems to be。
这个句子包含两个从句：
【The reason why laughter can reduce pain 】这是一个定语从句，先行词是reason，why是关系副词，“笑能减轻疼痛的原因”.......
The reason why laughter can reduce pain seems to be ...,1,主语是“the reason”, "why laughter can reduce pain " 同位语从句，seems to be 应该是谓语，that是宾语，后面是宾语从句。,1,一个英语句子结构的分析---在线等---高手进
