英语 九年级上册 人教版 四清导航 单元语法精讲精练 ►概念：在复合句中用作宾语的从句叫宾语从句。 ►不同引导词引导的宾语从句 1．that引导的宾语从句：当宾语从句是陈述句时，用连接词that引导，that在口语、非正式语境中常被省略。 She said that she went to the park last week.她说她上周去了公园。 2．if或whether引导的宾语从句：当宾语从句是由一般疑问句变来时，要用连接词if或whether来引导。一般情况下二者可以互换使用。 I want to know if/whether he is waiting for me.我想知道他是否在等我。 【注意】下列情况中一般只能用whether引导： (1)与or not连用时。 I don't know whether he likes the movie or not.我不知道他是否喜欢这部电影。 (2)作discuss等词或作介词的宾语时。 We discussed whether we should close the shop.我们讨论了是否应该关闭那家商店。 (3)在动词不定式之前时。 We are discussing whether to go shopping.我们在讨论是否要去购物。 ►宾语从句的时态 1．如果主句是一般现在时，宾语从句的时态应根据实际情况来定。 I want to know if it will rain tomorrow.我想知道明天是否会下雨。 2．如果主句是一般过去时，宾语从句常用过去的某种时态。 I didn't know that my son lost the football match at that time.那个时候我并不知道我儿子输掉了足球比赛。 【注意】如果主句是一般过去时，宾语从句所表达的是客观真理或不可改变的自然现象时，宾语从句仍用一般现在时。 The teacher told us that the earth is smaller than the sun.老师告诉我们地球比太阳小。 ►概念：用来表达说话时的惊异、喜悦、气愤等情绪的句子叫感叹句。 ►结构 (1)What＋a/an＋形容词＋可数名词单数(＋主语＋谓语)!
