Hello, welcome to my english microgrants. Today we are going to learn non predicate verbs. Before the class, let's enjoy the pictures and read the sentences, then lay out the predicate and non predicate works. Look at the picture, 画出句语词中的谓语和非谓语动词。The boy playing football there is my classmate, 在单句中is谓语动词。playing非谓语动词。They joined the film given by popular stock. 句子中enjoined谓语动词given非谓语动词。The girl covered . her head to have . sleep句中covered谓语动词to have谓语动词。All is a very good job. Let's make a summary. 谓语动词是指动词在谓语中用句子中充当谓语，而非谓语是指动词在句子中充当非谓语。非谓语动词可以充当的成分有主语、宾语、补语、定表语、状语。如何判断非谓语动词的使用？Now look at the sentences. 分析，在句子中没有谓语动词，所以空格处填谓语动词，时态为现在进行时态is joining the girl is drawing in the classroom now？在该句中有谓语动词，但并列连词and连接两个动词，所以空格处使用谓语动词，并前后两个动词时态一致。The girl is drawing in the classroom now, and he looks very beautiful. 在该句中有谓语动词，并且没有连词，所以空格处使用非谓语动词。They go drain in the crash room now looks very beautiful. 分析，在该句中有谓语动词带有重复连词后，所以空格处使用谓语动词时态为现在进行时。The girl who is drawn in the classroom now looks very beautiful. 总结非谓语动词在句中使用的用法，一个句子中已经有一个谓语动词用，没有连词的情况下，另一个动词用非谓语动词。非谓语动词分三种形式，现在分词、过去分词和不定式。如何选择非谓语动词？Not look at the sentences. 在这一句中有谓语动词got而cat the early bus表目的，so the answer is to catch the early bus. 在本句中有谓语动词so而where，这是指女孩们穿着不同的衣服，所以用现在分词表示穿着vary。在本句中有谓语动词can hold，而这里的build是修饰library，表示被建成，so the answer is built. At the end of this class, i'll give you some tips, 表目的或将来用不定式to do表主动或表进行用现在分词表被动或完成时用过去分词。After class, let us do some exercise to enhance our memory. Thank you for your listening.
