初二英語上冊語法復習詳解（15）-隨句型變化而變化的詞
15) 肯定句變否定句及疑問句要變化的一些詞
1.some變為any。如：
There are some birds in the tree.There arent any birds in the tree.
但是，若在表示請邀請、請求的句子中，some可以不變。如：

與此相關的一些不定代詞如something, somebody等也要進行相應變化。
2.and變為or。如：
I have a knife and a ruler.I dont have a knife or a ruler.
3.a lot of (=lots of)變為many或much。如：
They have a lot of friends.（可數名詞）They dont have many friends.
There is lots of orange in the bottle.（不可數名詞）
There isnt much orange in the bottle.
4.already變為yet。如：
I have been there already.I havent been there yet.
