Question

改错题：

(3) Did Sam walked to school yesterday?
(4) There aren't some boys here.
(5) I want do my homeword now.
(6) They're my grandparent.
(7)She is learnt English now.

Answer 1

3. walked改成walk
Did即为过去式，所以其后的动词必须用原形。

4. some改成any
否定句中，some要变成any

5. want和do中间加入to
固定短语want to do sth，意思是“想要做某事”

6. grandparent改成grandparents
主语They和动词are都用了复数，指两个人，所以grandparent也必须用复数形式grandparents

7. learnt改成learing
时间状语now表明句子为现在进行时，且she和learn之间为主动关系，所以使用现在分词learning

Answer 2

walked去ed
some 改any
want to
grandparents
learning

Answer 3

3.walled变 walk 4.some 变any 5.want do之间加 to6.grandparents 7.learning ，希望帮到你
