It usually follows a verb, a preposition or an adjective. 在复合句中，一个句子充当宾语，叫做宾语从句，它通常位于动词、介词或形容词之后。 Step III. Practice精要练习 Let's do an exercise to practice. Please check the sentences that contain object clauses. You have three minutes to finish this exercise. Please press “PAUSE”. Let's check the answers. No. 1, 2, 4 and 5 contain object clauses. Step III. Guiding learning自主导学 There are three types of object clauses. 当宾语从句为陈述句时用that引导，可以省略。当宾语从句原形是一般疑问句时，用if /whether引导。 if / whether表“是否”，不做从句成分，不能省略。当宾语从句原形是特殊疑问句时，用原特殊疑问词引导，做宾语从句的成分，不能省略。 Choose the correct answers. Please press “PAUSE”. Let’s check the answers. whether和if都表“是否”，但与or not连用时，只能用whether。 二、语序 Do you like Peppa Pig? I wonder. 改为宾语从句是 I wonder if / whether you like Peppa Pig. 注意:宾语从句的从句部分是陈述句句序，也就是主语在前，谓语在后。 Turn the following sentences into object clauses. 三、时态 Now let’s talk about tenses in object clauses. 秘籍是“主现从不限、主过从必过、真理永一现”。 Fill in the blanks. 1. 当宾语从句的主句是一般现在时,从句根据需要选用时态,也就是“主现从不限”。 2.当宾语从句的主句是一般过去时，从句只能选用相应的过去时态，也就是“主过从必过”。 3. 当宾语从句表示客观真理、名言警句、自然现象等，始终使用一般现在时，也就是“真理永一现”。 四、否定前移 I think he will come here tomorrow.(变为否定句) I don't think he will come here tomorrow. 当宾语从句的主句是第一人称I/ We, 语动词是think, believe, suppose, expect, imagine等
