Module 9 Friendship 一、Key Grammar 疑问句作宾语从句 1. 一般疑问句作宾语从句 一般疑问句作宾语从句时常用连词 if 或 whether 引导。 Eg. Do you know if / whether it will rain tomorrow? He aked me if / whether I could lend him some money. ★只用 whether 的情况： 当 whether 后面与 or not 连用时； Eg. Let me know whether you can come or not. 介词后面只能用 whether; Eg. It all depends on whether they will come back. 在不定式前与不定式一起组成词组时。 Eg. We don’t know whether to do it next. Let’s go and ask Mr. Li. 2. 特殊疑问句作宾语从句 Eg. Can you tell me when we will start? They told me why they were late. 3. 当疑问句变为宾语从句时要注意： （1）要将疑问句语序变为陈述句语序； Eg. “Have you finished your work?” he asked Tom. ——He asked Tom if he had finished his work. （2）人称有时要作必要的调整； Eg. “Where will you go?” he asked. ——He asked me where I would go. （3）时态要与主句保持一致。 若主句是一般现在时，从句可根据实际情况选用任何时态。 Eg. I know that she is leaving China the day after tomorrow. He says that he has been ill for two days. Please tell me when you were born. 主句是一般过去时，从句可根据需要用相应的过去某种时态（一般过去时、过去将来时、过去完成时等）。 Eg. He aksed me where I lived. H
