There are many four lines<~~I have no idea what "many four lines" means! in the notebook for English. Students are asked to write down small<~~use "lower-case" instead of "small" letters in Italic script.
In the English textbook, On<~~no capital O needed; lower-case letters are generally used inside a sentence unless the word is a proper noun the four lines there are English alphabet<~~change "alphabet" to "letters" which are not composed of deep<~~use "dark" instead of "deep" color. Instead they are written in light cloor black<~~instead of "light cloor black" use "gray" so that they<~~change "they" to "students" (otherwise "they" will be referring to the letters!) can trace each letter to practice writing capital letters.
I hope this makes sense. Let me know if it doesn't.
