The teacher told us (that) the earth moves around the sun. 二、两大类型： whether/if引导的宾语从句: 意为”是否” whether与if通常可以互换，且常跟在ask、know、wonder、decide、unsure、 uncertain等之后引导宾语从句，引出两个或以上的可能性之一； whether/if在从句中也不充当任何成分，只起连接作用. 特殊情况：当从句后面有or not时，只能用whether，不用if 语序：从句必须用陈述语序 时态呼应：和前边一致 I wonder if/whether it will rain. 我想知道是否会下雨。 只用whether的情况 1. 在 whether ... or not 的固定搭配中 Let me know whether you can come or not. 告诉我你是否能来。 if 和 whether 一般情况下可互换，但注意以下情况： 2. 当宾语从在句首时，只能用whether Whether he will come, I don’t know.他会不会来，我不清楚。 3. 在不定式前 I don’t know whether to accept or refuse. 我不知道该接受还是拒绝。 4. 在介词之后，作介词的宾语。 I worry about whether I hurt her feelings. I don’t know __________ I’ll watch the races next year or not. I am not interested in _________ you’ll come or not. He doesn’t know _________ to stay. _________ it is true or not, I can’t tell. whether whether whether 有or not 用 whether 介词后用whether 动词不定式 前用whether Whether 句首用whether 选词填空（that /if/whether） I hope ________ I can find some good learning strategies. She asks ____________ she should listen to English podcasts. We don’t know ____________ he will come or not. Do you know _________ reading aloud helps improve pronunciation? My teacher finds ____________ taking notes is useful. that if/whether whether if/whether that 宾语从句的时态 I hear that she was a worker two years ago. I hear that she is an English teacher now. I hear that she will come back tomorrow. He told me that he liked playing football. I said that she would come. He says the moon goes around the earth.

Language points Point 1 Could you tell me if this sentence is correct in English? correct /kə'rekt/ adj. 正确的；恰当的 v.纠正 correct(adj. 正确的)→correctly(adv. 正确地)→correctness(n. 正确性) (1)be correct in doing sth 做某事是正确的 (2)the correct answer/way/method 正确的答案/ 方式/ 方法 ◆What’s the correct way to solve this problem? 解决这个问题的正确方法是什么？ correct  (adj. 正确的v. 纠正)强调“符合标准、规则或事实”，更正式。 right (adj. 对的 n. 权利)侧重“道德、伦理或主观判断的正确性”，更口语。 Point 2 He suggested that learners should read and take notes very carefully,... suggest v. 建议；提议 n. suggestion 用法：（1）suggest +(that)+宾语从句，从句中用should do 或者省略should，直接用动词原形。 （2）suggest + doing ... E.g: He suggested going out for a walk.他建议出去散步。 （3）give a suggestion 给出建议 follow one’s suggestion 遵循某人的建议 Point 3 Luogeng later introduced a reading and learning method... method /'meθəd/ n. 方法 辨析：method, way 与mean method 强调系统性、步骤化、条理性的方法，与with搭配。使用场合大多为科学、学术等。如：with this method 用这种方法。 way 强调通用、灵活的方式，与in 搭配。使用场合较日常、口语化。 如：in this way 用这种方法。 means 强调具体的手段或工具，常与by 搭配，且单复数同形。常用于交通、通讯等。如：by means of借助……手段。 Exercises 单项选择 一、单项选择。 A 1.
