To determine whether to use the Present Simple or the Present Continuous tense for each sentence, it's important to understand the context and meaning of these tenses:
- Present Simple is used for habitual actions, routines, and general truths. It describes actions that happen regularly or facts that are always true.
- Present Continuous is used for actions happening at the moment of speaking or temporary situations.
Let's apply this to the sentences:
1) I usually drink tea. Today I am drinking coffee.
- "Usually drink" indicates a habitual action, so we use the Present Simple.
- "Today I am drinking" indicates a current, temporary action, so we use the Present Continuous.
2) He usually eats lunch at one o'clock. Today he is eating lunch at 2:00.
- "Usually eats" is a routine, so we use the Present Simple.
- "Today he is eating" describes what is happening now, hence the Present Continuous.
3) She is reading now. She often reads in the evening.
- "Is reading now" describes an action happening at the moment, so the Present Continuous is appropriate.
- "Often reads" describes a habitual action, hence the Present Simple.
4) Lewis is washing the car at the moment. He usually washes it every Saturday.
- "Is washing at the moment" is happening now, so we use the Present Continuous.
- "Usually washes" is a routine, thus using Present Simple.
5) Maria rides her bike every day. She is riding her bike now.
- "Rides every day" indicates a habitual action, so Present Simple is used.
- "Is riding now" describes a current action, hence the Present Continuous.
6) James and Mike usually wear jackets but today they are wearing T-shirts.
- "Usually wear" indicates a habitual action, hence the Present Simple.
- "Today they are wearing" indicates what is happening now, so we use the Present Continuous.
