Revise the conclusion of sick sentences

For a long time, I have always thought that modifying sick sentences is the teaching content of senior grades. After all, it's quite difficult. In the second grade, it is enough to learn how to use words and write good sentences, and the rest is difficult for them.

But in the first week of this semester, as planned, there was a paragraph to eliminate sick sentences. At first, I was confused. It's really difficult to teach such a difficult thing to second graders. I have been thinking and looking for a simple and interesting method, but it is not easy. Until I passed a clinic two days later, I had a brainwave and thought of a way: treat sick sentences as patients, my students are doctors and I am a "medical professor"; I am responsible for teaching "little doctors" how to diagnose, prescribe and operate.

But they didn't know what a sick sentence was before. How can we make them understand what a sick sentence is? I think of many short stories that make jokes because the characters are incomplete and unclear. So, I decided to introduce this kind of story, taking it as an example to let them know what a sick sentence is, instead of using concepts. Sure enough, the use of this set in class immediately aroused students' interest. After laughing, many of them can tell me what are sick sentences in their own words. This problem is solved, so the next step is the "prescription". So what is a prescription? I equate this with the modified symbol. In fact, it is no stranger for students to modify symbols, because the teacher has corrected the composition for one semester, and I also introduced them to them one by one last semester. This time, I just need to tell them that this is a prescription for modifying sick sentences and then review the usage. When I really came to class, I found it more interesting to review these recipes with students than to introduce them one by one as revision symbols before.

Two conceptual problems are solved, and the next step is to teach students how to "diagnose" and determine "symptoms". According to the syllabus, this lesson mainly talks about sick sentences from two aspects: the basic structure of sentences and the transformation of sentence patterns, of which the former is the focus. Because I started with the sentence structure, I decided to focus on the incomplete components, plus the simplest and most common "ba" sentences and "bei" sentences, which were caused by improper conversion. I don't think it is necessary for the latter professor to master the children who are already familiar with the conversion of "Ba" and "Bei" sentences (in fact, the same is true when coming to class). The difficulty of the problem lies in the incomplete composition. If we want to speak from the three aspects of "subject, predicate and object", it must be too abstruse and too deep for second-grade children. What should I do? After much consideration, I decided to give up the idea of "subject and object" and give a simple example, such as: "I am a primary school student." The basic structure is "xx is xx." It is divided into three parts: ××, ×××, ×××. No matter which part is missing, it will be an incomplete sentence. Then there are "how to ×××" and "how to ×××", so that when I show the sick sentence again, the "little doctors" can quickly find out the "cause". After knowing how to "diagnose", in the step of "prescribing medicine", many little guys have "learned without a teacher" and immediately started their own "surgery", and they are very interested. As for what some students didn't master accurately, I stressed that we should try our best to let them master when I took the exam results (classroom exercises).

After several pleasant "consultation on sick sentences" classes, I rejected all the ideas that it is difficult to teach sick sentences in junior grades. I deeply realize that no matter how difficult a subject is, as long as it is not bound by tradition and trapped by difficulties, it can be thought from an easy place, break the traditional model and teach it in another way, and students can master it well!
