Harbin is a beautiful city in __________ China.是填north还是填northern,为什么?由于刚才充忙,---_________________?---Pretty good.And you?How are you?还是 How is it going?为什么?

northern是形容词（northern China），north是名词(in the north of China),所以选northern

northern
northern 是 adj.
north是n.
这里填形容词。

north China
north可以是名词“北方，北部”也可以当形容词和副词

northern,如果是north，则是the north of

northern
north of China

northern 这样就把它变成形容词了

Harbin is a beautiful city in northern China.
north 名词，北方
northern 形容词 北方的
当然，这句话也可写作：
Harbin is a beautiful city in the north-east of China.
哈尔滨时中国东北一个美丽的城市。
祝你进步！

1 north 名词,北方
northern 形容词 北方的
China是名词
修饰名词要用形容词 ,所以填选northern ,若用north 则为the north of
2 选How are you?意思是身体怎么样
而How is it going?意思是事情进展的怎么样了?一般不会回答说And you?

China是名词
修饰名词要用形容词
north是名词
northern是形容词，所以填选northern
如果非要用north则使用短语the north of
