教学过程 教学环节 教师活动设计 学生活动设计 设计意图 Step 1: Lead in Review Review the five basic sentence patterns learned in Unit 1. T: Class, do you remember the five basic sentence patterns we learned in unit one Let's review it first! 基本句型一：S+V （主＋谓） 基本句型二：S +V +P （主＋系＋表） 基本句型三：S +V +O （主＋谓＋宾） 基本句型四：S +V +O+O （主＋谓＋间宾＋直宾） 基本句型五：S +V +O +C （主＋谓＋宾＋宾补） Review sentence patterns, on the one hand to consolidate what students have learned, on the other hand to strengthen the relationship between new and old knowledge, for the following grammar knowledge to pave the way. 复习句型，一方面巩固学生所学知识，另一方面加强新旧知识之间的联系，为后面的语法知识做铺垫。 Step 2: Presentation Simple sentence A simple sentence is made up of one independent clause which has one subject-verb combination. T: What do you think the sentences we just reviewed belong to I saw a cat. I saw a cute cat. S: They are simple sentences. Tip: Sometimes two or more juxtaposed subjects have a common predicate, or even two juxtaposed predicates, and such sentences are still simple. eg: Lucy and I often work together and help each pound sentence. A sentence containing two or more independent subject-predicate structures or simple sentences is called a compound sentence. They are usually joined by commas, semicolons, or parallel conjunctions. (1) A compound sentence indicating a relationship and, not only…but also…, neither…nor… eg: He gave me a present,and I like it very much. The juxtaposition of disjunctive relations but, while,yet eg: He is old but he is in good health. He is tall while his sister is short. A compound sentence indicating a choice relationship or,either..…or…,not.but… eg: Either you are right,or I am． Complex sentence A sentence consisting of one main clause and one or more subordinate clauses is called a complex sentence. The main sentence is the main part of the compound sentence, and the subordinate clause is the part that modifies the main sentence or some component of the main sentence. In the main sentence, clause can act as subject, object, predicate, appositive, attributive, adverbial and so on. eg:Check all your answers before you hand in your paper A doctor is a person who looks after people's health.（定语从句） What he did made his mother very angry.（主语从句） Parents shouldn't give their children whatever they warn.(宾语从句） This is because you are too careless.（表语从句） The girls were surprised at the fact that ocean ships can sail up the Great Lakes.（同位语从句） Explore and explain different sentence structures and their features to help students better understand the differences between them. 对不同的句子结构及其特征进行探索和解释说明，帮助学生更好的理解他们之间的区别。 Step 3: Practice Match each sentence with the correct type in the table below. simple sentences: 2,3,4,6 compound sentences: 5,8,13 complex sentences: 1,7,9,11,12 Point out the sentence type.
