注意区别与and的用法，and通常用于连接主语或宾语，连接主语时， 如果有I, I通常放在 and 之后，如：

Play with ldquo;和hellip;一起玩耍rdquo;ldquo;玩hellip;rdquo;

I often play with my pet dog. Donrsquo;t play with water!

复数形式为：leaves, 类似的变化还有：wifemdash;wives, wolfmdash;wolves,

knifemdash;knives等。 7、hour n. 小时;点钟

hour前边通常加上冠词an 表示ldquo;一个小时rdquo;， 即：an hour。

特殊疑问句通常以ldquo;whatrdquo;、ldquo;whordquo;、ldquo;whichrdquo;、ldquo;whenrdquo;、ldquo;whererdquo;、 ldquo;howrdquo;、ldquo;how oldrdquo;、ldquo;how manyrdquo;等开头，对某一具体问题进行提问。 特殊疑问句的基本构成有两种情况：

1. 疑问句+一般疑问句结构。这是最常见的情况。例如： Whatrsquo;s your grandfatherrsquo;s telephone number? 你爷爷的电话号码是多少?

Who is that boy with big eyes? 那个大眼睛的男孩是谁? Which season do you like best? 你最喜欢哪个季节? When is he going to play the piano? 他什么时候弹钢琴? Where does he live? 他住在哪儿?

How are you? 你好吗? How old are you? 你多大了?

How many brothers and sisters do you have? 你有几个兄弟姐妹?

2. 疑问句+陈述句结构。这时疑问词作主语或修饰主语。例如： Who is on duty today? 今天谁值日?

Which man is your teacher? 哪位男士是你的老师?

我们学过的What/How about+名词/代词+其他?也是特殊疑问句，它是一种省略结构。 例如：

I like English. What/How about you? 我喜欢英语。你呢? What about playing basketball? 打篮球怎么样? nbsp;

Unit 4 I want to be an actor. 一.短语：

1 want to do sth 想要作某事

2 give sb sth = give sth to sb 给某人某物 / 把某物给某人

3 help sb do sth 帮助某人作某事

Eg: I want to help my mother do some housework at home.
