初二英语语法大全:随句型变化而变化的词

15)肯定句变否定句及疑问句要变化的一些词

1. some变为 any如:

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:

3. a lot of(= lots of)变为 manymuch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.
