kind 还有“种类”的意思如：一种a kind of各种各样的all kinds of 不同种类的different kinds of --We have all kinds of beautiful flowers in our school.2、China n.中国Africa n.非洲China 和Africa都是专有名词，首字母都应该大写，而且和介词in连用。

--There are many kinds of tigers in China.--There are many kinds of scary animals in Africa.3、friendly adj.友好的，和蔼可亲的它是名词friend的形容词形式，同义词kind，常常和be动词连用, be friendly。

--The people in Chengdu are very friendly.4、with prep.跟，同，和…在一起--I usually play chess with my father.（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：My father and I usually play chess together.）Play with “和…一起玩耍”“玩…”--I often play with my pet dog.--Don’t play with wa ter!6、leaf n.叶子复数形式为：leaves, 类似的变化有：knife—knives 7、hour n.小时；点钟hour前边通常加上冠词an 表示“一个小时”，即：an hour。

特殊疑问句的基本构成有两种情况：1. 疑问词+一般疑问句结构。

这是最常见的情况。

--What’s your grandfather’s telephone number?你爷爷的电话号码是多少？--Who is that boy with big eyes?--Which season do you like best?--When is he going to play the piano?--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. 疑问词+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？3. What/How about+名词/代词+其他？也是特殊疑问句，它是一种省略结构。

--I like English. What/How about you?--What about playing basketball?打篮球怎么样？根据首字母，填出正确的单词。
