Period 3　Grammar—the －ing Form 整体设计 教学内容分析　　　 This teaching period mainly deals with the grammar：the －ing form.In the English language， the －ing form of a verb may be a present participle or a gerund.The form is identical and the difference is in the function ， or the job it does in the sentence.The present participle is most commonly used： (1)After verbs of movement/position in the pattern. (2)After verbs of perception in the pattern.The gerund always has the same function as a noun(although it looks like a verb)． In this period we will focus on only part of the usages of the present participle，that is，the present participle used as the adverbial. 三维目标设计　　　 Knowledge and skills 1．To get the students to know the different forms and usages of the present participle. 2．To enable the students to use the present participle as the adverbial correctly and properly.
