Studies show that young people with higher-than-average blood pressure and their families have a history of high blood pressure are more likely than others to develop a severe form of the condition.
A and their families have a history of high blood pressure
B whose families have a history of high blood pressure
C and a history of high blood pressure runs in the family
D whose families have a history of high blood pressure running in them
E with a history of high blood pressure running in their family
OA：B
LZ选的是C
RON解释的C的错误原因：
1 has one very glaring correctness issue: modifiers NEVER start with "and". the whole thing about the history of high blood pressure has to be a modifier, modifying the young people;
2 not only is this not a modifier (because it starts with "and"), but it doesn't even tell us that we're talking about the young people's families. it merely says "the" family. not acceptable.
3 by the way, the improper use of the conjunction "and" makes (c) not even a sentence at all.
即
1.modifier不能以and开头
2.the family不一定是young people的family，their families更好----->这个LZ懂了
3.and作为连词，让句子run on了
LZ关于and的疑问：
1.如果把and看成将history和blood pressure并列呢？
Studies show that young people with higher-than-average blood pressure and a history of high blood pressure（that) runs in the family are more...
这样第二个modifier就不是以and开头的了呀？and只是连词，其实是with a history.....，with省略了而已。以及pressure后面也省略了一个that
2.and作为连词并不是一定要连接两个句子呀，连接两个并列的elements不就可以了嘛？像上面这样理解的话，就没有run on了呀？
希望有大神解惑嘤！先谢谢啦！
