I think (that) he is honest. 3. 时态一致 主句与从句时态关系： 主句时态 从句时态 例句 现在时 根据需要选择任何时态 I know he is/was/will be here. 过去时 用相应的过去时态 He said he was tired. 客观真理仍用现在时 The teacher said the earth goes around the sun. 三、宾语从句的类型 1. 动词后的宾语从句 常用动词：say, tell, know, think, believe, hope, wonder, find out等 例：I hope (that) you can come to my party. 2. 介词后的宾语从句 例：We are talking about whether we should go. 注意：介词后的宾语从句一般不用that引导 3. 形容词后的宾语从句 常用形容词：sure, certain, glad, happy, afraid, sorry等 例：I'm glad (that) you passed the exam. 四、特殊用法详解 1. if 与 whether 的区别 情况 用whether不用if 例句 介词后 We talked about whether it would rain. 与or not连用 I don't know whether or not he will come. 作主语/表语 Whether he will come is still unknown. 在不定式前 She hasn't decided whether to go. 2. that 的省略与保留 可省略的情况： 主句谓语是常见动词（think, believe, say, know等） 例：I think (that) you are right. 不可省略的情况： 从句置于句首时 That he is honest is known to all. 主句与从句之间有插入语时 He told me, believe it or not, that he would go abroad. 并列宾语从句，第二个that不省略 I know that he is honest and that he works hard. 3. 否定转移 当主句谓语是think, believe, suppose等，且主语为第一人称时，从句的否定常转移到主句 例：I don't think he will come.（不说：I think he won't come.） 五、常见错误提醒 1、语序错误（最易错！） Do you know where does he live Do you know where he lives 2、时态不一致 He said that he will come tomorrow.（主句过去时，从句应用过去将来时） He said that he would come tomorrow. 3、if/whether误用 I'm thinking about if I should go. I'm thinking about whether I should go. 4、that多余 I wonder that who will come. I wonder who will come. 5、缺引导词 I know he is right is true. I know (that) he is right. 1．They are talking about _____ can be the best monitor. A．who B．what C．which D．where 2．—Father’s Day is coming. Shall we make a card for Dad —Good idea!
