Sample Writing
Several measures have been taken to deal with the“small waste” problem of cigarette butts in our community. Our streets now have many special small bins for putting cigarette butts in. Drains have special small grills to stop cigarette butts getting into the water system. They can both be cleaned easily. I think the measures have been effective, but still more can be done. The benefits of the measures are that they make it easier to dispose of butts and collect them. The disadvantages are that they don't stop the problem, as cigarettes still get smoked, and butts produced. Our assessment is that the measures were effective, but smokers need to be educated more about why not to drop their butts and to dispose of them properly.
Vocabulary
trillion num. 万亿
contain v. 遏制，防止……蔓延；抑制（感情）
toxic adj. 有毒的；极其有害的
