There are some birds in the tree.【改为一般疑问句 并作否定回答】
There are some birds in the tree?No,there aren't.
错误解析：一般疑问句要把be动词,助动词提到句首,因此
纠正：Are there some birds in the tree?No,there aren't.
There are [a lot of books] in the bookcase.【对括号部分提问】
Where are some books?
错误解析：where 是对地点提问的,但是括号部分的意思是许多书,因此提问应该问多少
纠正：How many books are there in the bookcase.
I can see [four] pictures on the wall.【对括号部分提问】
How many pictures on the wall?
错误解析：这道题目提问的疑问词是正确的,用how many ,但是句子意思不完整,而且句子缺少动词,没有动词句子就不完整,另外没有把上面的句子完全表达出来.应该把I can see 也放在疑问句中
纠正：How many books can you see on the wall
下面是选择适当形式填空
They like[ ]【make】model planes.
like +doing 喜欢做某事,不能加动词原形.
纠正 ：They like【making】model planes.
