Ask and answer in pairs.
1. How old are you

3. What grade are you in
英语有两种基本语调: 一种为升调，发音时，结尾元音往上挑，升调符号为“↗”；一种为降调，发音时结尾元音下降，降调符号为“↘”。
(1) 读升调的情况:
① 一般疑问句读升调。如：
Are you from China ↗
句子语调
② 几个字母、数字等连续读时，前面的读升调，只有最后一个读降调。如：
A ↗ B ↗ C ↗ D ↗ E ↗ F ↗ G ↘
One ↗ Two ↗ Three ↗ Four ↗ Five ↘
③ 多个单词并列时，要连续读出，前面的用升调，最后一个用降调。如：
She has a small head, ↗ small eyes, ↗ and a small nose. ↘
④ 选择疑问句or前用升调，or后用降调。如:
Is your hair long ↗ or short ↘
(2) 读降调的情况：
① 陈述句读降调。如：
She has a round face. ↘
② 特殊疑问句读降调。如：
Who’s this man in that car ↘
③ 祈使句读降调。如：
Close the door, please. ↘
come from 意为 “从……来、来自······”
come from = be from
表示某人来自某一地方
e.g. They come from America.
他们来自美国。
—Where are you from 你是哪儿的人
—I am from Beijing. 我是北京人。
语言点
Come from 的特殊疑问句和一般疑问句
I’m from China. = I come from China.
— She comes from Canada.
Where does Jane come from
Is Jane from Canada
Does Jane come from Canada
注意：通过上述例子，我们可以发现：come from 的特殊疑问句和一般疑问句要借助助动词do/does来完成
2. …year(s) old… ……岁了
这是一种表达年龄的方式，有时也 可省去。如：
He is five years old. 他五岁了。
=He is five.
We are in different schools.
= We are not in the same school.
same 相同的
Tom and Jim are in different schools.
Lily and Lucy are in the same school.
结论：same和different都可修饰名词。Same修饰名词时，前面要加定冠词the,后面要跟可数名词的单数形式；different修饰名词时，后面通常要跟可数名词的复数形式
different 不同的
3. have可以表示“有” 的意思，在一般现在时中，它的用法有哪些呢？下面我们一起来探究一下。
