1. read
Yun Jung: I am read a book.
Correct: I am reading a book./ I read a book everyday.
Explanation: When using a 'be' verb or linking verb in an active sentence, the verb that follows is in progressive tense or -ing. This means that the action is ongoing or happening at the moment of speaking. But if you mean to say that you do this everyday, then you can use the simple present tense to express a habitual action. This is constructed by adding the base form of the verb after the subject.

2. sing
Student: she heard the birds sing?
Correct: She heard the birds sing./ Can she hear the birds sing?
Explanation: When stating a declarative sentence, use period as your puntuation. But if you mean to ask a question, start the sentence with a modal, or helping verb. In this case, the modal 'can' was used to ask about the ability to hear of the person being talked about. This time, you can use a question mark. In addition, write sentences with a capital letter at the beginning.

3. jump
Student: can you jump rope.
Correct: Can you play jump rope?/ Can you jump over the rope?
Explanation: Jump rope is a noun; it is the name of a children's game or an exercise for children and adults in which a rope is swung over and under the standing jumper, who must leap over it each time it reaches the feet. You can add the verb 'play' to indicate the action. But if you mean to ask if the person you are talking to has the ability to jump over the rope, then, use the preposition 'over'. Either of this questions need to end in a question mark. In addition, write sentences with a capital letter at the beginning.

4. write
Student: I`m read a write.
Correct: I can read and write./ I am reading a letter.
Explanation: If you mean to say that you have the ability to read and write, follow the first sentence. 'And' is a conjunction used to add a word to another. Instead of using 'am' as the subject, you can use 'can' to express the ability. But if you want to tell that you are doing the action at the moment of speaking, then use the progressive tense of the verb or -ing. If that is the case, instead of using write, perhaps you mean to say 'letter'.

5. run
Student: I don`t run.
Explanation: There is no grammatical error in the sentence if you mean to say that you are not doing something because you are forbidden/restricted to do it for some reason.
