that, whether / if 引导的宾语从句 在复合句中，由一个句子充当宾语，这个句子叫作宾语从句。我们需要从三方面来学习由that, whether / if 引导的宾语从句。 一、关联词 1. 陈述句作宾语时，宾语从句用that引导。that只起连接作用，没有实际意义，在从句中不充当任何成分，因此常省略。如： He can visit Beijing one day. My brother hopes. (合并为含有宾语从句的复合句) My brother hopes (that) he can visit Beijing one day. 2. 一般疑问句作宾语时，宾语从句用whether或if引导。whether和if意为“是否”，在从句中不充当任何成分，但不可省略。如： Is Tom's sister an English teacher? May wants to know.  (合并为含有宾语从句的复合句) May wants to know whether / if Tom's sister is an English teacher. 二、语序 that, whether / if 引导的宾语从句要用陈述句语序。如： Will she go to Beijing tomorrow? I don't know.  (合并为含有宾语从句的复合句) I don't know whether / if she will go to Beijing tomorrow. 三、时态 1. 如果主句是一般现在时，that, whether / if 引导的宾语从句可根据需要使用适当的时态；如果主句是一般过去时，that, whether / if 引导的宾语从句用相应的过去时态(一般现在时→一般过去时，现在进行时→过去进行时，一般将来时→过去将来时，现在完成时→过去完成时，一般过去时→过去完成时)。如： Andy knows (that) his wife bought a nice dress yesterday. I want to know whether / if my father will go to London next week. Jack believed (that) Mary made up the story. Mary wondered whether / if Jenny was watching a movie at 8:00 p.m. yesterday. 2. that, whether / if 引导的宾语从句表示客观事实或真理时，其时态不受主句限制，用一般现在时。如： The teacher said (that) China lies in Asia. 感叹句     感叹句是用来表达喜、怒、哀、乐等强烈情感的句子。感叹句可由what和how引导。感叹句句末常用感叹号。 ▲what引导的感叹句(what用来修饰名词)，常见结构如下： 1. What + a / an +形容词+可数名词的单数形式(+主语+谓语)! 如： What a kind woman (Mrs. Steen is)! What an interesting movie (it is)! 2. What +形容词+可数名词的复数形式(+主语+谓语)! 如： What lovely children (they are)! 3. What +形容词+不可数名词(+主语+谓语)! 如： What delicious food (it is)! What good advice Mr. Green has given us! ▲how引导的感叹句(how用来修饰形容词、副词、谓语动词等)，常见结构如下： 1. How +形容词 / 副词(+主语+谓语)! 如： How clever (the boy is)! How carelessly Peter did his homework! 2. How +主语+谓语！如： How time flies! 【温馨提示】 一般情况下，以what和how开头的感叹句可以相互转换，转换后意义不变。如： What an important meeting it is! = How important the meeting is! that, whether / if 引导的宾语从句 Ⅰ. 用that或whether / if填空 1. Susan hopes _______ she can visit Beijing one day. 2. I want to know _______ Alice will go to the zoo with us tomorrow.
