Please call me if you want to go there. a list of 意为”的清单/单子” Youd better make a list of your mistakes. list 作动词，意为“将单子制表” He has listed the names of the students who didnt finish doing their homework. 常用短语：a shopping list 购物单 put sb/sth on the list 将某人/某物列在单子上 take sb/ sth off the list 将某人/某物从单子上除掉(3) When you have finished reading a message, click on “Close.” have finished 意为“已完成了”，是现在完成时。现在完成时的构成为”have/has +过去分词”，表示过去发生的某一动词对现在造成的影响，动作是发生在过去，但强调对现在的影响或结果依然存在，属现在时的范畴。 -Why havent you gone to the cinema? -Because I have seen the film. finish reading 意为“读完”。finish 意为“完成”，后接v.-ing形式。 I finished writing . 类似finish只能用v-ing形式而不用不定式作宾语的词还有：enjoy, keep, mind, practice, suggest, dislike, excuse, consider等。 I enjoy playing football. He is practicing speaking English. He kept writing .(4) Its always nice to hear from Wu Hong!hear from sb 相当于get/receive a letter /an e-mail/ a phone from sb,意为“收到某人的来信/邮件/电话”。I often hear from my uncle.hear from 还可意为“从处得知”I have heard from your mother that you are in Beijing .hear of/about 意为“听说”，其后常接名词或代词I often hear of the place.“hear +that 从句”意为”听说”I have heard that you are learning Japanese.“hear + sb+ doing sth”意为”听见某人正在做某事”，表示主语亲耳听见He heard the boy making noises.“hear sb+do sth”意为”听见某人做了某事”，听见的是动作的全过程或动作经常发生，也表示亲耳听到。Iheard him climb upstairs.3. 根据对话内容，选择恰当的句子补全下列对话 A: Good morning .Can I help you?
