分析句子的语法成分

So if a mother breastfeeds that mean that by eating vegetables, her baby will be exposed to the flavors of vegetables through her breast milk.

尤其是breastfeeds后面的2个that分别做什么成分，mean跟哪个that相连，如何解释，请把全句的语法成分解释全，谢谢

Answer 1

解析如下
Sometimes at night you might see a light move quickly across the sky.
这句话的意思是:有时在夜里你可能看到一道光迅速地划过天际.
see sb./sth do sth.看到某人/某物做某事
see sb./sth doing sth.看到某人/某物正在做某事
由于句意并无正在进行的意思,所以用see sb./sth do sth.
如果你将move改为moves,语法上也没有错误可以see后面可以处理成宾语从句,后面是一个完整的句子a light moves quickly across the sky.但为了明显,可以在句子前面加that.

求该文章上一句和下一句

第一个that指代前面的“if a mother breastfeeds”，mean是谓语，
第二个that引导的是宾语从句，在这里不充当句子成分，可以省略。
by eating vegetables是方式状语
