This ESL writing lesson introduces students to run-on sentences
and how to correct them, after which several run-on sentences
are presented for the students to rewrite and correct. A run-on
sentence is when two complete sentences are put together without
correct punctuation (a comma or period, for example). You should
avoid run-on sentences when you write! This is actually two
sentences: We went to the beach. and It was a lot of fun. To
correct this, you can add a period: > We went to the beach. It
was a lot of fun. (Right!) Or you can add a conjunction (and /
but / so / because) between the sentences. (Note: With
“and/but/so” you need to use a comma (,), but with “because” you
usually don’t need a comma.) > We went to the beach, and it was
a lot of fun. (Right!) > We went to the beach because it is a
fun place to go. (Right!) > John is sick. He hasn’t gone to the
doctor. (Right!) > John is sick, but he hasn’t gone to the
doctor. (Right!) > I didn’t finish my homework. The teacher is
not happy with me. (Right
