In the IELTS Speaking exam, you often need to talk about yourself or other people. Here are some useful words/phrases to do this...
a glass half full person is a person who is an optimist (noun) and always looks at things in a positive way.
a glass half empty person is someone who is a pessimist (noun) and looks at things in a negative way.
