A complex sentence contains one main clause and at least one subordinate clause. A compound sentence contains at least two main clauses and no subordinate clauses.

We can convert a complex sentence into a compound sentence by changing the subordinate clause or clauses into main clauses.

Note that subordinate clauses are introduced by conjunctions like because, as, if, when, where, since and though. The conjunctions commonly used in compound sentences are: and, or, but, yet and for.

Change the following complex sentences into compound sentences.

1. Walk carefully lest you should fall.

2. Although she is rich, she is not happy.

3. As soon as we heard the gunshot, we rushed to the spot.

4. If you are honest, you need not fear anybody.

6. Though he is brave, he is careless.

7. You will pass if you work hard.

8. He could not catch the train because he was late.
