由图可清晰明了地看出后测学生的做题人数总体来说有明显提升，但第10-1

After the test students can be seen from Figure clarity to make the number of questions in general has improved significantly, but the effect is not the first 10-16 questions so obvious. After measuring the number of correct measurement decline or no change over the previous, careful analysis of the reasons is the cause of this decline may be partially correct rate is the use of this part of the stick figure is not clear enough, the students did not really grasp the components of a good analysis of the relative pronoun. Or they stick figure compared to other teaching methods and teaching methods better suited to explain this part. But this does not prove that stick figure used to explain parts of no use. But measured before and after the 7-8 gap problem is very large, it proved student understanding and ability to use and when carried out during the past now can be improved.

From the figure can clearly see that the number of students after the test of the overall number of significant improvement, but the effect of the 10-16 question sq. The number of correct post-tests decreased or did not change compared to the previous test, the reason for careful analysis is that the reason for this part of the decline in accuracy may be that the use of this part of the sketch is not clear enough, students do not really grasp the relationship pronoun analysis of the various components. Or other teaching methods and methods are more suitable for this part of the explanation than simple strokes. But it does not prove that the explanation of the sketch is useless in these parts. But the 7-8 question before and after the test gap is very large, proving that students in the current and past when the understanding and use of the ability to improve.

It can be clearly seen from the figure that the number of post test students doing questions has increased significantly in general, but the effect of questions 10-16 is not so obvious. The number of the correct people in the post test is lower than that in the pre test or there is no change. The reason for the decrease of the accuracy is that the use of the simple strokes in this part is not clear enough, and the students do not really master the component analysis of the relative pronouns. Or compared with the simple strokes, other teaching methods and teaching methods are more suitable for this part of the explanation. However, it does not prove that the use of Jane's strokes in these parts of the explanation is useless. However, the gap between the pre-test and the post test of 7-8 questions is very large, which proves that students' understanding and application ability of present continuous tense and past continuous tense can be improved.
