Unit 4 Space explorationperiod 3 Discovering useful structures教学设计课题Describe space facts andefforts to explore space单元Unit 4学科English年级高二教材分析This lesson is period 4 of Unit 2. The theme of the activity is "Describe space facts and efforts to explore space." When people discuss the topic of space exploration, the use of infinitives as attributives and adverbials is very common in both oral and written expressions, from the perspective of semantic construction and pragmatic function. The purpose of this section is for students to grasp and use this structure to describe known facts about space, important events in the history of space exploration and the achievements of important people.The core structure of this unit is the use of infinitives as attributives and adverbials. In junior high school, students have learned to use infinitives as adverbials of purpose. This unit adds the use of infinitives as adverbials of result. When an infinitive is used as an attribute, it is used to modify nouns, pronouns, numerals, etc. When an infinitive is used as an adverbial, it can express purpose, result, cause, accompanying state, etc.学情分析This lesson is aimed at the Senior One students.
