We had a heated discussion about... Different people hold different opinions. Opinions are divided. People have taken/adopted different attitudes towards... People have different opinions on this problem. People take different views on this question. 2. 表达不同观点: ...of them hold the opinion that... ...of them are in favour of the idea that... People who are for/against the idea think... Some people believe that...Others argue that... 3. 不同观点之间的衔接用语: However,...of them hold a different view./...of them hold the opposite opinion.
