题目内容：

SAT 语法 纠结死偶啦,..
一个关于this
1.OG P801/4
The information age hasushered children into a global society,this situation causing educators to lament a lack of texts that explain the diversity of cultures.
"this situation causing educators to lament"成"a situation causing educators to lament",官方解释是this 指代不明,但这又引起了我的另一个困惑,
2.OG P864/14 一题是这样的
High school graduates usually do not end up earning as much income as college graduates do,this being why so many high school students go on pursue college degrees.
这题答案是改" do,this being why so many high school students "成"do; this fact explains why so many high school students "
倘若1题中的this有指代不明的嫌疑,那么2题中的this不也有指代不明的嫌疑?
