Homework

Today, I wake up at 1:00 pm. Yesterday, I had cold and headache so I took a medicine. Because of that, I wake up late. I was aware of it and I threw the medicine away to the trash can. I can't go to the mall for shopping because it's very rainy and the medicine had a terrible effect. While talking with teacher I said that I'm not feeling so good. Anyway, I have to go to bed.

Explanation:

1. Always remember to capitalized the first letter of the word on the beginning of your sentence.

    Example:   a. today, I wake up at 1:00pm. - Today, I wake up at 1:00pm.

2. Always remember the correct irregular from of a verb which is in past tense.

    Example:   a. waked - wake

                   b. frustrated - frustrating

3. Always remember to check the meaning of the words that you will use in your sentence. If it's not appropriate in your sentence avoid using it.

    Example : The medicine had a terrific effect. ( "terrific" means intense happiness.)

                   The medicine had a terrible effect. ( "terrible" very bad feeling.)
