If you've been assigned to write a descriptive and an informal paragraph, you must be the one who writes them or you will be violating the expressed or implied honesty contract you have as a student to submit your own work. So, I can't write your paragraphs for you. What I can do is give you some easy guidelines for writing your own.
For a descriptive paragraph, first choose something you know well. The more familiar you are with the subject matter, the quicker and easier it will be for you to write it. Look around your living space or think about a familiar spot on campus or in your life.
Second, choose something that has multiple layers of description. That means finding something which appeals to as many senses as possible. Here are some ideas to consider:
- the contents of your closet or wastebasket (you can be selective if you don't want to share everything)
- your desk
- your vehicle
- someone you know very well
- one of your favorite places to visit
- your view from the seat you always occupy in a classroom
- the view from your window
- your favorite meal
- a room in your house (or whatever is applicable)
- one intriguing thing in your life (anything creative, interesting, or unique that invites description)
- the contents of your refrigerator
You get the idea. These are all things you either know well without having them directly in front of you or they are things you do have right in front of you and can easily describe.
Third, choose a pattern for your description: top to bottom, inside to out, front to back, or by the senses. Doing this will not only help you identify a place to start but will also keep you moving as you write.
Next, utilize sense imagery to make your audience feel as if they know all aspects of whatever you're describing. Tell your reader how it looks, smells, sounds, or tastes. You don't have to use all of them unless it seems reasonably natural to do so. Details, details, details.
If I were describing my television remote, for example, I might start with something like this:
My television remote is about eight inches long and, like many remotes, it's black. Most of the buttons are clear and have black writing on them, though much of the writing has worn off from constant use. The buttons which are kind of turquoise blue are the "Power" button and four odd petal-shaped buttons which are at the bottom of the remote and placed in the formation of a flower. I can push them down like every other button on the remote, but they don't seem to do anything but break the monotony of all the little square and round buttons above them.
Finally, begin and end strong. While the focus of a descriptive paragraph is of course on the description, you want to leave your readers with something that feels satisfying. I might end the paragraph above with something like this:
My remote is not as high-tech as some others I've seen, but I know how to work it and that's what matters most to me.
It's a paragraph, not an essay, and I encourage you to just choose something and then sit down to write. It's not a difficult task.
Great descriptions create vivid images in the mind of the reader, making them fun and memorable to read.
As for a stand-alone "informal paragraph," I've never heard of it. The term informal is generally used to describe how a paragraph is written. In this case, your informal descriptive paragraph would include contractions ("I've" instead of "I have," for example) and be characterized by a personal tone between you and your readers.
Descriptive paragraphs are things you'd see in novels where items people and things are described using alot of descriptive language like "her hair flowed on the wind each strand shone like silver spagetti" (XD haha) etc...
An informal paragraph is similar but has relaxed grammer I like to think of it as talking to a professor or dean compaired to talking to a friend or family member. Talking to a friend is much more informal then talking to a dean.
A descriptive paragraph needs to have facts. There needs to be exact points in the reading that you can cite as your sources. There should be very little imbelishment and you should use proper grammar.
An informal paragraph can contain facts but you can expand on them. you can write about how you feel and your opinions of the reading. If it is truly an informal paragraph you may use slightly more lax grammar such as contractions (isn't, you've, weren't, etc.)
