*SENTENCE COMBINATION*

Learning to combine ideas into more complex sentences is an important writing skill. There are many ways to do this. Try to combine the following three sentences. Do not use a semi-colon.

Sentence 1: Yuri did poorly on his  final exam last week.
Sentence 2: He stayed up very late studying before the exam.
Sentence 3: Research shows that getting a good night's sleep before an exam is important.
