1_ Someone says they think magazines are a waste of money . Disagree , giving a reason

2_ A friend from England calls and asks about the weather . You see dark clouds in the sky

3_ One of your friends watched a football match on TV and found it boring . You have a different opinion

2- Itis cloudy , it'sgoing to rain
3- I think it isn't boring
