EAP 140 PM - WANG, Lingshan - Week 9 1/4

We called an independent clause which in a sentence hasn't been joined in a right way is run-on sentence.   Independent clauses are word groups, so they can't stand along like sentences.  We should put two independent clauses in one sentence.  We have two ways to use, we can choose one of them. 1) with a comma and a coordinating conjunction(and,but,yet,so,or,for,nor). 2)with a semicolon(or occasionally with a colon or a dash).

e.g.
The girls played basketball, but the boys played tennis. 
I like apple,  but my father like pear.
I don't think I can get high score in this test, but I get a good mark.
I like eating fruits and drinking milk.
