✔ 最佳答案
Include these elements should be enough for a 2 mins talk:
1. Exactly what this new facility is.
2. The reason for installing this new facility.
3. In what way will this facility aid with students' learning. Short term/Long term benefits.
4. Any disadvantage(s) after installing this new facility and how to overcome it.
This should be enough for a 2 mins talk; I advice you to stay calm, speak slowly and clearly, don't rush, then 2 mins will pass before you know it!
Hope it helps!! =)
