Plastic brings us convenience, and pollution as well.
Some very tiny pieces of plastic are called microplastics (微塑料). The largest microplastics can be directly seen.
Since plastic is everywhere, researchers suggest that we should be careful with possible microplastics in life. They may be from baby toys, pens, and even phones we use every day.
根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
| A．What’s worse, it’s everywhere. |

| D．Use plastic products widely in our daily life. |
| E．All in all, we should use plastic products properly. |
| F．But many of them are small enough to be around us without being seen. |
| G．Also, the heat of your drinks will encourage microplastics to get into your drinks. |
