Explanation:

A school notice must be a brief, succinct, direct and objective text. This notice must contain simple and clear language so that it can be understood by anyone.

The notice must address your objective in a very objective way and in case you are informing about an event, such as the notice above, it must present the time, place and activities that will be carried out.

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.

what is your question?
