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. June 4b Read June’s letter and underline the objective clauses. 宾语从句的种类 ①I believe that there are many ways to show our love. ②We are talking about whether we invite Miss Li to the birthday party. ③I am glad that you can go to a university in Beijing. 动词宾语从句 介词宾语从句 形容词宾语从句 that引导宾语从句时无词义，在从句中不充当成分， 可以省略。 e.g. I hear (that) she will be back next week. e.g. He told me (that) the new store was great. 连词 whether / if引导宾语从句，意为 “是否”，不充当成分， 不可以省略。Whether 和 if一般情况下可以互换。 e.g. I wonder if you’ll be back next week. e.g. I can’t decide whether the school will have sports meeting. 连词 Ⅲ. if和whether的区别 二者在下列几种情况下不能换用： 1. 宾语从句与or not直接连用时，应用whether，不能用if。 I don’t know whether or not he will come tomorrow. 我不知道他明天是否来。 2. 与动词不定式连用时，只能用whether。 She can’t decide whether to go to America. 她不能决定是否去美国。 3.在介词后通常用whether It depends on whether I have enough time. Grammar I know _____________ the Water Festival is really fun. I wonder _____________ they’ll have the races again next year. I wonder _____________ June is a good time to visit Hong Kong. I believe ______________ April is the hottest month in Thailand. (that) whether / if whether / if (that) 练习 用合适的引导词完成句子。 1.当主句的时态是一般现在时， 则从句根据时间状语、语境选择合适时态。 e.g. I hear that she will come back tomorrow. e.g. I remember you gave me a pen yesterday. e.g. Anna says she has seen the movie. e.g. I know you were watching at six o’clock yesterday. 时态 口诀：主现从随便 2.当主句是一般过去时， 则从句为四种带“过”字时态中的一种。 e.g. My father said that he was watching TV at that time. e.g. My mother said that he had already cleaned the house. e.g. He said that she visited her grandparents last weekend. 时态 口诀：主过从必过 3.若从句是真理、事实规律的句子，无论主句什么时态，从句都用一般现在时。 e.g. She explained that two and two is four. e.g. He says that the moon goes around the earth. 时态 口诀：客观事实永不变。 观察下列句子，请圈出主句谓语动词和宾语从句的谓语动词。 I think (that) you are right.
