As follows:
1. Life is really difficult now. I can’t even refuel, which makes me feel like my pockets are really empty!
2. The speed of making money can never keep up with the speed of spending money. I can’t even refuel. Sometimes I feel very helpless!
3. This is probably the tragedy of my life. I couldn’t afford to refuel. From then on, I started walking to work!
4. The sky is vast, the earth is vast, and prices are rising. I can't afford to buy a car, but I can't afford to fill it with gas. The public transportation is quite busy, so those who own cars will end up in trouble.
5. I am so poor this month that I can’t even refuel.
