Natural fuel sources are important to us, and we are in desperate need of it. But we use it too wasteful of avf used too much, so they are slowly running out. So in the future, sooner or later, those energies will expire soon. They are gas, oil, coal, ... Then, if we do not have timely treatment, we will be severely short of raw materials. All activities will be immediately suspended, and we will be very miserable. First, we will not have electricity to light all daily activities, and they will become very difficult. The second is for cooking, we have to use the straw stoves, straw stoves, while today we often use gas stoves. There are also many other issues like raw materials for production, for moving. Next is the environment is heavily polluted after we use those energy sources. In short, the consequences are enormous. However, we can stop it by using renewable energies like wind, solar energy, tidal energy, which last forever, and they don't pollute the environment. I hope in the future everyone will use renewable energy sources to make life better.

CT thì hiện tại đơn:
(+) S + V(s/es) + O
(-) S + don't/ doesn't + V + O
(?) Do/Does + S + V + O?
Tobe: am/is/are
- Nếu chủ ngữ là số ít, he, she, it thì tobe là is và V phải thêm s/es.
- Nếu chủ ngữ là số nhiều, you, we, they thì to be là are và V giữ nguyên.
- Nếu chủ ngữ là I thì tobe là am và V cũng giữ nguyên.
