How an OHP Is Used
An overhead projector (ohp) is a device that casts a transparency image on a screen. The process of on ohp includes the following steps. First, an ohp is placed on a table positioned several feet from a screen ,and it is pluged into an electical socket. Next, a transparency is placed face up on the plate glass surface of the ohp ,and the switch is turned on . Finally, the height of the ohp is adjusted so that the image is centered on the screen and,a focus knob is turned until the clear image is projected.

Thank you, Hajar for your great work. I am really happy to have a student like you in my class.
I enjoyed reading your process paragraph.
the following is my feedback:
1. ohp = OHP
2. pluged = plugged
3. a focus = the focus
4. the clear = a clear
5. Sentence (5):
After that, the height of the OHP is adjusted so that the image is centered on the screen and,the focus knob is turned until a clear image is projected.
6. Missing sentence:
Finally, the transparency is replaced with the next transparency, and the sixth step is repeated.
Thanks, again, Hajar!
