1. Please don’t speak loudly in public.
2. I can make a lot of friends by taking part in team games like basketball and football.
3. I will keep my mobile off when I am having classes, so / but you can send me short
messages.
4. Unusual weather indicates that our living environment is getting worse, which is the
warning to us from nature.
5. The purpose of our meeting today is to discuss how to solve the problem, not who (has)
caused it, so please don’t waste time arguing about who is to blame (any longer).
