A. why people live there B. how people make a living C. why do people live there D. how do people make a living B Grammar Object clause 宾语从句 9 (3) 时态 主句是现在或将来的某种时态，从句的时态可根据实际情况使用所 需要的任何一种时态。 e.g. I know that he is a student. 我知道他是一名学生。 She says that she saw a movie yesterday. 她说她昨天看了一部电影。 He believes that it will rain tomorrow. 他认为明天要下雨。 You will find that this book is fun. 你会发现这本书很有趣。 练习：She believes ________ her daughter ________ up with the latest fashion soon. A. that; will keep B. if; will keep C. that; keeps D. if; keeps A Grammar Object clause 宾语从句 10 (3) 时态 当主句中的谓语动词是一般过去时态时，宾语从句则使用相应的过去时态。 e.g. I heard you had a bad cold. 我听说你患了重感冒。 注意：如果宾语从句所表达的内容是客观真理或客观事实时，从句中 动词的时态不受主句的谓语动词时态的限制。 e.g. The teacher said that Earth moves around the Sun. 老师说地球围绕太阳转。 He said he is forty. 他说他40岁了。 练习：The teacher told us that there _________ going to be a quiz show the next week. A. is B. was C. were B Grammar Object clause 宾语从句 11 that引导的宾语从句 ① that是引导宾语从句的常用词，很多时候可以省略，省略后句子意思 不变。但以下情况，that不能省略。 当宾语从句前有插入语时；插入语常见的有I think、I believe、I guess、he said等。 当句子结构比较复杂且从句前面有其他成分(比如宾语补足语)隔开时； 当主句的谓语动词(比如say、tell、think等)后面有多个宾语从句时， 第二个及以后的that不可省略； 为强调宾语从句本身的内容，或者为了句子结构更清晰时。 e.g. The truth is, I think, that you are right. 我觉得，事实上你是对的。 I made it clear that I didn't want to go to the party. 我明确表示我不想去参加派对。 He explained (that) the project was difficult and that he needed more time. 他解释了项目有难度，并且他需要更多时间。 I believe that practice makes perfect. 我相信熟能生巧。 Grammar 12 ② 否定前移 当主句的谓语动词是think、believe、suppose、imagine等词，且宾语从句表达否定含义时，常把否定前移至主句的谓语部分，从句仍用肯定形式。 e.g. 正确：I don't think he will come. (否定在主句)我认为他不会来。 错误：I think he won't come. (否定在从句) 练习：I _______ she _______ here on time because of the heavy traffic. A. think；won’t arrive B. don’t think；will arrive C. don’t think；won’t arrive D. think；would arrive B that引导的宾语从句 Grammar 13 ( ) 1. —What did Wei Fang say about her plan for the weekend? —She said that she ______ to visit the history museum next weekend.

I believe it _______ in the cold winter with its mom’s help. A. survives B. survived C. is surviving D. will survive D B B D 挑战一：单选题。 14 if/whether引导的宾语从句 当宾语从句的语意相当于一个一般疑问句时，常用if/whether 引导，表示“是否”。if/whether在句中不充当句子成分，但不能省略。一般情况下，if和whether可以互换。 e.g. I wonder if/whether you want to attend the meeting. 我想知道你是否想参加这个会议。 拓展：只用whether不用if的情况： 与or not连用时 引导介词后的宾语从句时 与动词不定式连用时 e.g. I don't know whether I should go there or not. 我不知道我是否该去那。 Let's talk about whether we should join the club. 我们讨论一下我们是否应该加入这个俱乐部。 He didn't decide whether to stay. 他没有决定是否要留下来。 Grammar 15 注意：当whether从句置于句首且引导让步状语从句时， 此时也不可与if互换。 e.g. Whether it will rain, Mom will take a numbrella. 不管会不会下雨，妈妈都会带伞。 练习： 1) I don’t know ________ he will come. ________ he comes, I’ll tell you at once. A. if; If B. whether; Whether C. if; Whether 2) —What’s wrong with your uncle? —We’re certain _______ something is wrong with him, but we are not sure _______ the disease can kill him.
