Whether he’ll take the job is still unknown. Where they’ll move their office to is not clear. When he’ll leave for New York hasn’t been decided. It is still uncertain whether he's coming or not tonight. 2. 宾语从句 e.g. I hope that people will spend more money on education. Do you know which football team Bill supports Would you mind telling me what shoe size you take I wonder whether I should accept the offer or not. He asked if I could show him how to operate the air conditioner. Choosing the right bike depends on what you want to use it for. 1) 当主句的主语是第一人称，且谓语为think, believe, suppose等动词时，如果宾语从句表示否定意思，通常否定前移，即否定主句的谓语。 e.g. I don't suppose they'd start the trip without us. 2) 宾语从句亦可用作介词的宾语。 e.g. If you've got any questions about what I've said so far, I'd be happy to answer them. 3) 引导宾语从句的连词that在口语中可省略，但在下列情况中，that需保留： a. 主、从句之间有表示时间等的状语时that不能省略，否则会产生歧义。 e.g. My friend Lisa said yesterday afternoon that she came across one of our classmates in the bookstore. 3. 表语从句 e.g. His suggestion is that we should hire more experienced people. That’s what we should do. That is how they succeeded. That is why he was late for school. That was when my mum was in hospital. Things were not as we had expected. 1) 当主语是reason且后面的表语从句表示原因时，通常用that引导；而当it，this或that作主语，后面的表语从句表示原因时，常用because引导。 e.g. The reason everyone is cheering is that it's just been declared a national holiday. It / This / That is because you are saying too much. 2) 表语从句还可由as if / as though引导，主句中的动词可用be, seem, appear, look, taste, sound, feel等。 e.g. He looked as if / as though he hadn't washed for a week. It sounded as if / as though he were trying to say something. 三、引导名词性从句的连接词辨析 1. what与that 1) what引导名词性从句时不仅起连接作用，而且在从句中充当主语、宾语、表语、定语等。 e.g. John arrived two hours late: what had happened was that his bicycle chain had broken. Luis lost his job and was short of money, so what he did was to sell his flat and move in with his brother. My hometown is much different from what it was ten years ago.
