宾语从句应注意三点：①引导词，陈述句一般由that引导，这时的that可以省略；一般疑问句则由if或whe-ther引导；而特殊疑问句则由特殊疑问词引导。
②时态，主句是现在时态，从句可用所需要的任何时态；但如果主句是过去时态，从句时态所表示时间一般往前移一个时间段。
①如果主句是现在的时态，从句的时态可根据实际情况而定。
如：I have heard（that）he will come back next week.②如果主句是过去的某种时态，那么从句的时态一定要用过去的某种时态。
如：He said（that）there were no classes yesterday.注意：如果宾语从句表述的是客观真理、自然现象等时，不管主句是什么时态，从句都要用一般现在时。
如：He said that light travels much faster than sound.B.人称的变化和标点的使用1. 从句的主语如果是第一人称，变为宾语从句则与主句的主语一致；如果是第二人称，则与主句的宾语一致；如果是第三人称，不用变化。
如：“May I use your knife？”He asked me.→He asked me if he might use my knife.“Do you know her telephone number？”He asked me.→He asked me if I knew her telephone number.③语序，宾语从句永远要用陈述句顺序。
①陈述句变为宾语从句，语序不变，即仍用陈述语序。
如：He is an honest boy. The teacher said.→The teacher said（that）he was an honest boy.②一般疑问句和特殊疑问句变为宾语从句，语序变为陈述语序。
如：Does he work hard？I wonder.→I wonder if/whether he works hard.When did he leave？I don’t know.→I don’t know when he left.注意：有些疑问句本身就是陈述语序1.Who went there yesterday? Mary wanted to know.→Mary wanted to know who went there yesterday.2.What’s the matter with the clock? He wondered.→He wondered what was the matter with the clock.A)if和when既能引导时间状语从句，又能引导宾语从句。
因此，遇到它们就要认真分析一下。
如：If it rains tomorrow，I won’t come.（时间状语从句）I don’t know if it will rain tomorrow.（宾语从句）B)从句的简化1. 当主句谓语动词是find，see，watch，hear等感官动词时，从句常简化为“宾语＋宾补”结构，宾补为不带to的不定式或V-ing形式。
如：She found that the wallet lay on the ground.→She found the wallet lie on the ground.She found that the wallet was lying on the ground.→She found the wallet lying on the ground.2. 当主句谓语动词是hope，wish，decide，forget，plan，agree等，且主句主语与从句主语相同时，从句可简化为不定式结构。
如：She agreed that she could help me with my maths.→She agreed to help me with my maths.3. 在连接代词/副词引导的宾语从句中，当从句主语与主句主语或间接宾语一致时，宾语从句可简化为“连接代词/副词＋不定式”结构。
如：Can you tell me how I can get to the station？→Can you tell me how to get to the station？变人称，语序为陈述语序，标点，时态看看下面的题1).How does he get on with his new classmates? Could you tell me?
