TTGWD29-19显然指代有歧义啊啊啊啊,为什么是这样

Q19:

Critical-thinking instruction is predicted on two assumptions:  that there are clearly identifiable thinking skills that students can be taught to recognize and apply appropriately, and if recognized and applied, students will become more effective thinkers.

1. if recognized and applied, students
2. if these skills are recognized and applied, that students
3. if students recognize and apply them, that they
4. that if recognized and applied, students
5. that if students recognize and apply these skills, they

为什么是E啊?

that... and that... 平行

认清学生和recognize的主动关系

所以选E

If recognized and applied, students...

students 应该主动recognize apply,而不是被...

Critical-thinking instruction is predicted on two assumptions:  that there are clearly identifiable thinking skills that students can be taught to recognize and apply appropriately, and that
                    if students recognize and apply these skills,
                    they  will become more effective thinkers.

绿色：that从句的条件状语从句

青色：两个假设结构平行

黄色：后一个从句的主句

需要补充的是：D选项不是被动的表达，而是省略主语，但很不幸，宾语也被省略了，造成指代不明。

如果有F选项that if recognized and applied these skills, students
            那么，该选项也正确。
