肯定句变为否定句 技巧1： 当句中含有情态动词或助动词could，would，should等时，可直接在其后面加not构成否定句。例如： I could get you a concert ticket. → I could not / couldn't get you a concert ticket. 技巧2： 当句中含有系动词was，were 时，可直接在其后加not构成否定句。例如： I was on the Internet when you called me. → I was not / wasn't on the Internet when you called me. 技巧3： 当句中谓语是除情态动词、助动词、系动词was,were以外的动词时，在该动词之前加did not / didn't，动词还原，构成否定句。例如： The famous singer sang some Chinese songs. → The famous singer did not / didn't sing any Chinese songs.
