Read the【Case Reflection】in this section and answer the following questions:

Mr H has found the reading exercises in textbooks are beyond his students' ability, so he decides to rearrange the teaching materials by himself — he uses audio and visual aids in pre-reading activities; he designs comprehension questions according to the reading texts; and he arranges discussion for post-reading activities. Thankfully, the students have become more active in class, and they seem to respond well to the comprehension questions. One semester later, however, Mr H is disappointed to find that the students are not getting better at comprehension questions in the final exam. He cannot figure out the reason why most students are able to give right answers in class, but still get one or two questions wrong when taking the exams. What do you think are the main problems with Mr H's teaching?
