肯定句变否定句及疑问句要变化的一些词 1.some变为any。如： There are some birds in the tree.→There aren't any birds in the tree. 但是，若在表示请邀请、请求的句子中，some可以不变。如： Would you like some orange juice? 与此相关的一些不定代词如something, somebody等也要进行相应变化。 2.and变为or。如： I have a knife and a ruler.→I don't have a knife or a ruler. 3.a lot of (=lots of)变为many或much。如： They have a lot of friends.(可数名词)→They don't have many friends. There is lots of orange in the bottle.(不可数名词) →There isn't much orange in the bottle. 4.already变为yet。如： I have been there already.→I haven't been there yet. (责任编辑：admin) |
