Question

They ___(每个） have a nice hat.What colors are the ()?They're ___(orange)

Answer 1

They ___(每个） have a nice hat.
They是主语，可以填all 或者each作同位语。

What colors are the ( )?They're ___(orange).
第一空填oranges，因为谓语为are所以主语the oranges必须为复数。
第二空填orange，此处orange为形容词作表语。

Answer 2

填each

1)every总是修饰单数名词，后接单数动词。
(2)each作为形容词，修饰单数名词，接单数动词。作为代词，单独使用，接单数动词；放在复数名词和代词后作同位语，接复数动词。
(3)each of +名词复数作主语，后面的谓语动词用单数。(1)every one,Eg:Every one of them goes to the same factory.
(2)Each man carries his own bag. （修饰单数名词）
Each carries his own bag. (代词)
They each have their own office. (作We的同位语).
(3)Each of them goes to a different factory.
