My mother bought two fish today (fish так и остается, потому что множественное и единственное число этого слова неизменно). They are very fresh.
I want something to drink now. (want - глагол чувства и восприятия, а они не употребляются в present continious)
My mum said that I need do more exercises. (глагол need не изменяется во всех временах)
The cakes are still warm. They were baked early in the morning.
There were two women in the garden.
