Can someone help me write an introduction about qualities of a good student?

Answer and Explanation:

sure,

in a nice introduction you should include a topic sentence, evidence/ examples, and the conclusion or transition.

You can begin with a topic sentence such as:

A good student can be successful in school and in life as whole, these students often consist of many positive characteristics that help them throughout their studies.

You can then move on to providing examples of the characteristics, such as good work habits and etc. Lastly conclusion is the final sentence that will allow you to move on to describe each example in depth throughout the rest of the essay.

the present continuous is a verb tense which is mainly used to indicates that an action is in progress at the moment of speaking.  

it is formed using: person + verb to be (am/is/are) +verb + - ing form  

example: i am studying at this moment .

in addition, the present continuous is also used in order to express things that will or will not happen in the near future.

example: i am having dinner with some friends tonight.

the speaker sometimes   uses it   to express that an action is repeated and it causes irritation on the part of the speaker

example: my sister is constantly complaining about everything.

"a" because he is appealing to logic as oppose to appealing to the audience's emotions.
