When to use 'I go swimming' and 'I swim'? And,what are the differences between them? Are they suitable to use.
To go swimming is to spend some time swimming (in a swimming pool or the sea etc.) for pleasure or exercise. To swim is just to propel yourself through the water.
If you fall into water by accident and can swim to save yourself from drowning, you don't call it going swimming. On the other hand, if you go swimming regularly you might say "I swim at the nearby pool every day".
A good answer to the question, "What do you do in summer when you are uncomfortably warm?" could be

Both answers are perfectly acceptable. Moreover, "I go swimming" and "I swim" say the same thing with slightly different wording. The verb in "I swim" is present tense; the verb in "I go swimming" is present participle. Here are a few sentences which illustrate how the two sentences can be used:
When I get hot in summer, I swim. Sometimes I swim alone, and sometimes I go swimming with friends. When I am swimming in a pool, I like to have plenty of room all to myself. When the pool is crowded, I swim, but I am not comfortable swimming. That's because I keep bumping into people.
In the public pool near my home, between 4 PM and 5 PM, the lifeguards install lane barriers so that people can swim laps without bumping into anyone. I swim in lane number 6 because I like swimming close to the edge of the pool.
I go swimming in the ocean when my family goes on vacation to Myrtle Beach in South Carolina. I swim usually in the early morning when the beach is almost empty. I go swimming late in the day because the beach is not crowded then either.
