The floor was littered with papers. Even the bottom of the river was full of rubbish. There were no more fish for fishermen to catch. I put more coal on the fire. What ugly things! Throw them away. There are other advantages of bike riding. It's good for health and it doesn't cost anything! The total cost to you is 3 000. I never take wooden chopsticks or plastic forks when I buy takeaway food. The pipes are made of plastic. These plastic bottles can be reused. Let's have a takeaway tonight. And remember to throw rubbish in the bins and keep public places clean and beautiful for everyone. Read the passage about sharks and complete the fact sheet below. Many have heard of shark fin soup. This is not only cruel, but also harmful to the environment. Fruit juices can be harmful to children's teeth. Sharks are at the top of the food chain in the ocean's ecosystem. Many believe that sharks can never be endangered because they are the strongest in their food chain. The global warming will surely influence the ecosystem. But in fact, around 70 million sharks are caught and traded in this industry every year. They have even asked governments to develop laws to stop the sale of shark fins. So far, no scientific studies have shown that shark fins are good for health. We’ll not take part in the sports meeting. Can we afford a new car? For example, you can save electricity by turning off the lights when you leave a room. You can also use reusable bags instead of plastic bags. I think it's a great idea that you now have to pay for plastic bags in some stores. Let's take action now! I think that everyone should use public transportation. Recycle books and paper. Don't use paper napkins. Do you often throw away things you don't need anymore? Have you ever thought about how these things can actually be put to good use? <grammar> *现在进行时 *现在完成时 *被动语态 |
