Use this invented notice: "The upstairs study room will be closed on Thursday morning for maintenance. Booked sessions will move to Room Two on the ground floor. Please check in at reception before your session."
Read once for the practical situation. Ask three questions: Which room is affected? When does the change apply? What should a person with a booking do? The notice concerns one period, not a permanent closure.
Find the language supporting each answer
"Thursday morning" limits the time. "Booked sessions will move" explains that the sessions continue elsewhere. "Please check in" gives an action rather than background information. Underline these phrases before consulting a dictionary.
If "maintenance" is unfamiliar, the other sentences still reveal the essential arrangement. You can look up the word afterward to understand the reason more precisely. This does not mean every unknown word is unimportant; an unknown word in the required action may need immediate checking.
Write a one-sentence message to a friend: "Your Thursday-morning session is in Room Two, and you need to check in at reception." Then compare it with the notice. Do not add an afternoon closure or a canceled booking, since neither is stated. This exercise connects reading comprehension to the real task of passing on accurate, actionable information.
