三、短文填空(26-40 題,請選出最適當的選項) Passage 1
Do teachers who know more about their subjects have a more positive impact on their students?
When we look at teachers' knowledge of facts and concepts, 26 measured by test scores and
college grades, the relationship to student learning is unclear and may be indirect. Teachers who know more facts about their subjects do not necessarily have students who learn more. But teachers who
know more may make clearer presentations and recognize student difficulties more 27 . They
are prepared for any student questions and do not have to be evasive or vague in their answers. 28 ,
knowledge is necessary but not 29 for effective teaching because being more knowledgeable
helps teachers be clearer and more organized.
