1.  I never wrote a research essay in high school; therefore, I did poorly in my EAP class.

2.  Young teens see actors smoking in popular movies, so the teenagers begin to smoke.

3.  University of Alberta is farther away from my hometown than UBC; as a result, I

decided to go to U of A.

4.  Sometimes students put so much effort into their studies that they eventually have to drop out from university.
