Teaching reflection 【教学反思】
When teaching the comparative and superlative degrees, a lot of students understood the basic rules by looking at example sentences and making simple comparisons.Using real objects and pictures made it easier for them to use the grammar.
However, there were some problems. The exercises we had were too similar. Some students still made mistakes when they had to use the grammar in more difficult sentences. We should add more exercises that are like things they see every day. Also, some students didn't talk or participate much. We need to get every student to practise more so that they can really learn this grammar well.
