1. power my home with renewable energy,reduce water waste and buy better bulbs.

2.

 I have decided to enter university after graduating from secondary school for the following reasons:

+It doesn't mean that I will get a job easily if I have an university degree but it will open up more options to me.

+ It is the only way for me to follow my dream of being a doctor. If you want to get a career, not just a job, you must have a degree which allows you to progress in your career faster than without a degree.

+ With degrees, I can track my career, I can work at a higher level, then I can earn more money.

+Studying for a decree teaches me to be an independent thinker, how to work in a team, how to communicate well with others...

3. I want to visit Hoi An because :

Hoi An’s unique fusion of cultural influences reveals itself within its narrow streets. Weathered shop-houses squeeze shoulder-to-shoulder alongside ancestral homes, their tiled roofs decorated in exotic wood carvings. Tucked away from the old ferry quay, you’ll find an open market, pagodas and a timber bridge that once connected the town's Japanese and Chinese communities. Hoi An is even better in the evenings, when the faded streets glow in the light of thousands of lanterns.

4.I don’t think so because the environment is being destroyed so life is getting more and more difficult.
