2. that从句中含有主从复合句。如：
I’m afraid that if you’ve lost it, you must pay for it.
3. 主、从句之间有插入语时。如：
It says here, on this card, that it was used in plays.
卡片上写着，它是古代演戏用的。

并列连词连接时，只有第一个连词that可以省略。如：

if或whether引导宾语从句时，作“是否”讲，一般情况下，两者常可换用。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。
我不知道他明天是否来。
I don’t know whether or not he will come tomorrow.
2. 与动词不定式连用时，只能用whether。

She can’t decide whether to go to America.

宾语从句
+
+
在复合句中，由一个句子充当宾语，这个句子叫做宾语从句。
定义： 用来表达喜、怒、哀、乐等强烈感情的句子叫感叹句。感叹句一般用what或how引导，句末用感叹号。what修饰名词，how修饰形容词或副词。
Presentation
1.What + a / an +adj.+可数名词单数（+主语+谓语+其他成分）！
他是多么壮的一个小伙子啊！
What a strong boy he is!
玛丽是一个多么诚实的小女孩啊！
What an honest girl Mary is!
2.What + adj. + 可数名词复数（+ 主语 + 谓语 + 其他）！
这些书籍真有趣！
What interesting books!
3.What +adj.+不可数名词（+主语+谓语+其他成分）！

一、What开头的感叹句
1．How + adj.+ a / an +可数名词+主语+谓语+其他成分！
多么振奋人心的一场球赛啊！

3.How+ 主语 + 谓语！ 时间过得真快啊！
How time flies!
二、How开头的感叹句
拓展
1）在how引导的感叹句中，句中的主语和谓语可以省略：
How fast！ 多快呀！
How beautiful! 多美呀!
2）在感叹句中，What a / an 常用来修饰单数可数名词，若其前面的形容词为元音开头，则用 an。what 是用来修饰复数可数名词和不可数名词。但有些不可数名词，如 rain, surprise, breakfast, lunch 等，当前面有形容词修饰，使抽象名词具体化时，则要用 what a / an，如：
What a heavy rain it is! 多大的一场雨啊！
What a great surprise it is! 这多么令人惊奇啊！
What a rich breakfast it is! 多么丰盛的一顿早餐啊！
3）要修饰名词的形容词不能是表数量的many， much， little， few，遇此情况要用how，即使它们后面跟有名词：
How many books he has！ 他的书真多！
How much money he gave her！ 他给了她好多钱呀！
How little money I have！ 我的钱多么少呀！
How few friends he has！ 他的朋友真少！
比较：What a little box it is！ 多小巧的盒子呀！（该little不表示数量）
_____ a beautiful city it is！
_____ beautiful the city is！
3. _____ exciting the news is！
4. _____ an old building it is！
5. _____ brave the doctors and nurses are！
6. _____ quickly he runs at the sports meeting！
判断依据：去掉主语和谓语部分，中心词是名词时，那么感叹词用what;中心词是形容词或副词时，那么感叹词用how 。

Dear 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
4b
or mon 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.
