There are different ways in which two simple sentences can be combined.
The commonest way is by using a conjunction such as: and, but, yet, for, though, because, nor, so, etc. This method works best when the two sentences are independent clauses (which means they do not need each other to make sense.)
When the two sentences have the same subject , they can be combined by dropping the subject in one of the clauses.
In some cases, when the second clause is related to the first but not directly, a semi-colon can be used.
