1. Write about a natural disaster you have read about.

The most destructive disaster that I have experienced was the flood in 2012, in Thanh Hoa province. It had been raining heavily for many days. All homes, trees and animals were flooded. The water got to the roof of houses. Damage was caused to property and people. Many people were injured and died. Rescue workers helped people trapped in the flooded houses and they brought people who were left homeless to safe place. My house was flooded but we had been evacuated before. Although the time has gone by, I still can’t forget that terrible disaster.

5. To protect the environment, in my opinion, I should start with the small things that are closest to us. For example saving electricity: turn off the TV when not watching; Or do not forget to turn off the lights when going out, replacing more energy-efficient devices. Saving water: reusing water as vegetable wash instead of discarding it, you can water the plants in the garden; When washing dishes, wash in a basin, do not wash directly under running water for too long. Along with saving is keeping general hygiene. This is very important. To keep clean is to dispose of garbage in the right place; not cutting flowers to break branches destroying nature; not graffiti on the wall; When you see garbage falling on the street, you will pick it up and put it in the trash; is to plant some more trees in front of the house, etc. These everyday tasks are small, but they also play a part in protecting the environment. And if you alone do it, we will not be able to see the change in the environment for the better. But it takes the cooperation of many people to become a giant to protect the environment.

Giống như một thiên đường, căn phòng của tôi là nơi duy nhất mà tôi cảm thấy tự do, ấm cúng và thoải mái để thư giãn sau một ngày mệt mỏi ở trường.
Phòng của tôi có thiết kế đơn giản và mọi thứ trông gọn gàng và rõ ràng. Đó là một phòng đẹp bởi vì nó được trang trí bởi chính tôi. Tôi sử dụng màu sáng cho tường và các mối quan hệ màu xanh lam để truyền cảm hứng cho một cảm giác thân mật vào không gian. Bên cạnh đó, phòng của tôi trông ấm áp và thoáng mát với hai cửa sổ lớn ở hai bên phòng và một số đèn trên tường. Tôi thích máy tính trong phòng của tôi bởi vì nó giúp tôi rất nhiều cho việc học của tôi.
