This is an English-Chinese dictionary. 2. The dinner smells good. 3. My job is to teach you English. 4. The question is who will do it. （表语从句） 主语 + 系动词 + 引导词 + 其他成分 This is why he did it. 分析： What I want to say is that I am tired. 可以接表语从句的系动词有： 1. be动词：am, is, are, was, were 2. 感官动词：feel, seem, look, appear, sound, taste, smell 3. 表示状态：remain, keep, stay 4. 表示变化：become, get, grow, turn, go, fall 5. 证明：prove, turn out 引导词： that 在从句中不担任句子成分，无实际意义，一般不能省略。 如：The fact is that our team has won the game. 主语是“建议，劝说，命令”的名词，如idea, suggestion, order, request，表语从句中谓语动词用“should + 动词原形”，should可省略。 如：My suggestion is that we (should) leave early tomorrow. 引导词： whether 是否： The question is whether it is worth doing. if 不能引导表语从句。 as if, as though 好像，似乎，常置于连系动词look, seem, sound, is, become等后面。 It+连系动词(look/seem…)+that/as if 从句. 看起来似乎…… 如：It seems as if he knows everything. 他似乎知道所有事情。 引导词： because 因为，引导表语从句通常只用于“This/That/It is because…”结构中 如：I didn’t go to work yesterday. That’s because I was ill. 我昨天没有去上班，是因为我生病了。 why ……的原因 如：I didn’t do my homework, that’s why I was punished by my father. 引导词： why与 because 引导表语从句时的区别： why强调结果，because强调原因。 如：He was ill. That’s why he was sent to the hospital. He was sent to the hospital. That’s because he was ill. 注意： 主句主语为reason，只能用that引导表语从句，不可用because 句型：the reason (why…) is that … 如：The reason why I don't speak is that I'm shy. 我不说话是因为我害羞。 引导词： where, when, why, how引导的表语从句 连接副词充当时间、地点、方式、原因状语，本身具有词义。 如：That’s where I can’t agree with you. This is why Sarah was late for the meeting. This is how they overcome the difficulties. 引导词： 由连接代词引导的表语从句： 如：You are not who I thought you were. 你已不是我过去所想象的人。 The question is who(m) we should trust. 问题是我们应当相信谁。 引导词： 由关系代词what引导的表语从句： 如：That’s what I want to stress. 这是我想强调的。 That’s what we are here for. 我们来这里就为了这个。 Fame and personal gain is what they’re after. 他们追求的是名利。 He is no longer what he was. 他已经不是以前的他了。 表语从句一定要用陈述语序： False: The question is when can he arrive at the hotel.
