四、难点解析
1.“某人有某物”的表达方式———主语+have/has。
句型结构:“某人有某物”的句型为“主语+ have/has...”
【解析】have/has 的意思是“拥有”,当句中的人称为第三人称单数时,则把 have 变为has。
例句:We have a new teacher.我们有一个新老师。
Amy has a new desk.埃米有一张新课桌。
I have a new bed.我有一张新床。
【拓展】此向中主语为第一人称复数形式,故谓语动词用have;当主语为第三人称单数形式时,谓语动词用has.
2.用 Where is...? 来询问地点。
【解析】Where is ...?的意思是“……在哪里?”用来询问地点,某人的位置,某人来自哪里,物品的产地等。
例句: Where is your mother? 你妈妈在哪?
Where are you from? 你来自哪里?
Where is the school?学校在哪里?
3. Let's go and see! 我们去看看吧!
【解析】这是一个祈使句。let's 是 let us 的缩写形式,意为“让我们……吧”,后面接动词原形。
句型结构: Let's+动词原形+其他!
例句: Let's go shopping! 我们去购物吧!
Let's do homework first. 我们先做作业吧。
4.The door is orange. 门是橘黄色的。
【解析】此句是用来描述物体颜色的。当主语是复数形式时,be 动词用are。
句型结构:主语+be 动词(is/are)+表示颜色的形容词。
例句: The desk is yellow. 书桌是黄色的。
The window is green. 窗户是绿色的。
【拓展】表示颜色的形容词都可作名词,意为“……色”,如 black(黑色),white(白色),yellow(黄色)等。
例句:I like black. 我喜欢黑色。
My favourite colour is white.我最喜欢的颜色是白色。
5.There's a bee in our classroom.我们教室里有一只蜜蜂。
【解析】这是 there be句型的肯定句结构,表示“某处有……”。there's是 there is 的缩写形式,意为“有”。
句型结构:There+be 动词(is/are)+(a/an+)名词+介词短语.
例句:There is a fan on the wall. 墙上有一台风扇。
There are fifty students in our class. 我们班有五十名学生。
【注意】there be 句型遵循"就近一致原则",即 be 动词的单复数形式与离其最近的主语(名词)保持一致。
There is a pencil and three books on the desk.书桌上有一支铅笔和三本书。
There are three books and a pencil on the desk.书桌上有三本书和一支铅笔。
6.常用来表示地点的介词。
It is near the window.它在窗户旁边。
What's in the classroom?教室里有什么?
It's on the floor.它在地板上。
It is under the teacher's desk.它在讲台下面。
【解析】near 是常见的表示地点的介词,我们常见的表示地点的介词还有
in(在……里面),on(在……上面),under(在……下面)。
【拓展】想知道某物上面/下面/附近有什么,可以用“What's on/under/near +名词?”来提问。
