I think that mooncakes are delicious!Grammar Focus在复合句中，由一个句子充当宾语，这个句子叫做宾语从句。引导宾语从句的常见关联词有that, if, whether, what, where, why, how等。the Chinese Spring FestivalI think that we're busy visiting relatives.
I believe that all kids like this festival.
I know that it is a time for us to have a good rest.
I guess that we will put on some pounds.Object clauses with that, if and whetherGrammar（一）宾语从句 在句子中起宾语作用的从句叫做宾语从句。
We know Mr Green teaches English.
She asked if these answers were right.Ⅰ. if和whether引导宾语从句时，作“是否”讲，一般情况下，二者没有区别，可以换用。但if常用于口语中，whether比较正式。如：
Millie asked if/whether he liked this sweater.
米莉问他是否喜欢这件羊毛衫。
The fisherman wants to know if/whether it will rain.
渔民想知道天是否会下雨。Object clauses with if and whether由if / whether引导的宾语从句Ⅱ. if和whether引导宾语从句时，要注意宾语从句三要素，即连词、语序和时态。由于if和whether连接的是一般疑问句，因此要注意把从句语序改为陈述句语序。如：
Does Mr Zhao live in Room 208? Could you tell me?
→Could you tell me if/whether Mr Zhao lives in Room 208? Ⅲ. if和whether的区别,二者在下列几种情况下不能换用：
1. 宾语从句置于句首表示强调时，应用whether，不用if。如：
Whether this is true or not, I can’t say.这是否对，我不能说。2. 宾语从句与or not直接连用时，应用whether，不能用if。如：
I don’t know whether or not he will come tomorrow.
我不知道他明天是否来。3. 与动词不定式连用时，只能用whether。如：
She can’t decide whether to go to America. 她不能决定是否去美国。
4. 从句作介词宾语时，只能用whether。如：
I worry about whether I hurt her feeling. 我担心是否伤了她的感情。5. 宾语从句的谓语动词是否定形式时，只能用if，不能用whether。如：
Tom wants to know if he won’t come here tomorrow.
汤姆想知道他明天是否不来这儿。
6. if意为“假如，如果”时，可以引导条件状语从句，而whether没有这个用法。如：If Simon comes here tomorrow, I’ll call you.
假如西蒙明天来这儿，我将打电话告诉你。?当主句是一般现在时，宾语从句的时态不作限制，我们可以根据句子的意思来使用需要的任何一种时态。【时态】He will go to Hong Kong .
He is sick.
He is reading a book .
He has finished his work.he had finished his work.he would go to Hong Kong .he was sick.he was reading a book . ?当主句是一般过去时的时候，宾语从句必须运用相应的过去的某一种时态，从而达到主句和从句的相互一致。the sun is much bigger than the moon .Summer is after Spring .the earth moves around the sun. He told me (that)We knew (that)The teacher told us (that) ?当宾语从句说明的是客观存在的事实或者是客观存在的真理时，就不用受到主句时态的限制，仍是用一般现在时态。1. ( ) —Do you know ____ Jane visits her

Read the passage below and underline the objective clauses. If possible, write your own sentences about Mother’s Day and Father’s Day using objective clause.4bDear Xia Yu,
Do you know that there are two special days for parents in America?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.
Junetie n. 领带（可数）
复数形式：ties
e.g. I bought a tie for my
father yesterday.tie v. 系，捆，与to连用
e.g. Please tie your shoes.2. One is Mother’s Day on the second Sunday of May, and the other is Father’s Day… another, the other, others & the others
another和the other都有“另一个”的意思。another指多个中的“另一个”；the other则指两个中的“另一个”，常与one构成固定one ... the other ...，“一个……另一个……”。 e.g. The shoes don’t fit me. Would you please show me?_________?pair?鞋不适合我，你能给我看看另外一双吗？
? My sister has two skirts.?_____?is yellow,?__________?is black.
我姐姐有两条裙子。一条是黄色的， 另外一条是黑色的。others (=other+复数名词)与the others (=the other+复数名词)均含有“其他一些”的意思。others泛指多部分中的一部分，可与some构成固定结构some ... others ...，“一些……一些……”；the others则特指剩余的一部分。 e.g. Some?like fruit and vegetables, _____like junk food.
一些人喜欢吃水果和蔬菜，还有一些人喜欢吃垃圾食品。
