Section A Grammar Focus-4c Learning objects (学习目标) master the usage of grammar as below: Objective clauses with that, if and whether Exclamatory statements give personal reactions and statements about festivals. I know that the Water Festival is really fun. I wonder if they’ll have the races again next year. I wonder whether June is a good time to visit Hong Kong. I believe that April is the hottest month in Thailand. Grammar Focus 由that, if/whether 引导的宾语从句 宾语从句 宾语从句本质：用一个完整的句子，代替普通宾语（如名词、代词），来表达“动作的对象”。宾语从句必须跟在“有实际动作的词”（如动词know/think/say，或形容词sure/afraid）后面 一、定义 在句子中起宾语作用的从句叫做宾语从句。 I know the girl. 做宾语 主语 谓语 宾语 做宾语 从句 I know that the girl is a student. 主语 谓语 宾语从句 结构:主句+ 连接词 +宾语从向 2.连接词: that 无词义 可省略 陈述句 if/whether “是否” 不可省 一般疑问句 wh-疑问词 不可省 特殊疑问句 宾语从句需要用“引导词”连接主句和从句，核心是that、if、whether，用法完全不同 1. 她说她喜欢英语。→_________________________________. 2. 我知道他是我的同学。 → ____________________________________. 1.陈述句:（ 引导词that，无实际意义，可省略。) I know that the girl is a student. 主语 谓语 宾语从句(陈述句) She says (that) she likes English I know (that) he is my classmate 2.一般疑问句:-引导词if，有实际意义，不可省 I wonder if the girl is a student. 主语 谓语 宾语从向(一般疑问句) 当主句有“疑问、不确定”的语气（如动词ask/wonder，形容词not sure），从句是在问“是…还是不是…”时，用if，翻译为“是否”，且if不能省略。注意：从句要用“陈述句语序” 1. 他问明天是否下雨→________________________________. 2. 我不确定她是否在家→ _____________________________. He asks if it will rain tomorrow I’m not sure if she is at home 3.特殊疑问句 引导词whether：和if几乎一样，“是否”有实际意义，不可省。能用if的地方大多能用whether I wonder whether the girl is a student. 主语 谓语 宾语从句(特殊疑问句) 但以下3种情况只能用whether，不能用if： - 场景1：从句后面有“or not”时（“是否…还是不…”）。 - 场景2：从句跟在“介词”（如about/of）后面时。 - 场景3：从句跟在动词不定式之前时。 但以下3种情况只能用whether，不能用if： - 场景1：从句后面有“or not”时（“是否…还是不…”）。 例：我想知道他是否会来还是不来→ I wonder whether he will come or not.（不能用if） - 场景2：从句跟在“介词”（如about/of）后面时。 例：我们在讨论是否去公园→ We are talking about whether we will go to the park.（不能用if） - 场景3：从句跟在动词不定式之前时。 例：我们正在讨论是否去购物。→ We are discussing whether to go shopping.（不能用if） 主句使用现在时，从句可使用任何时态； 主句使用过去时态，从句一律使用过去时态。 当宾语从句是客观真理或不可改变的自然现象时，宾语从句须用一般现在时，不受主句时态的限制。 I think that you are right. Lin Tao thought the TV play was very boring.  Our teacher told us that light travels faster than sound. 宾语从句的时态取决于主句的时态。 宾语从句的时态 Exercise I think_________ Halloween is a fun festival. I want to know ________it’s good news or not. I worry about __________I hurt her feelings. I can’t decide _________to stay. I wonder _________they’ll have the races again next year.

One is Mother’s Day on the second Sunday of May, and the other is Father’s Day on the third Sunday of June. On these two days, American children often give gifts to their parents or take them out for lunch or dinner. Common gifts are flowers and cards for mothers and shirts or ties for fathers. I heard that it is becoming more and more popular to celebrate Mother’s Day and Father’s Day in China. I wonder if children over there also give similar gifts to their parents. I believe that there are many ways to show our love. Actually, we don’t have to spend a lot of money. It is also a good idea to help parents to do something instead.
