问题: What do you do when you see rubbish on the street?

If I see rubbish on the street and there’s a bin nearby, I usually pick it up and throw it away. I think it’s important to keep the city clean and set a good example for others.

When I notice rubbish on the street, I usually pick it up and throw it away if there’s a bin nearby. I care about keeping my city clean and feel a sense of responsibility for the environment. Plus, I think it sets a good example for others to follow.

1. 一般现在时：答案使用一般现在时（“I notice”，“I usually pick it up”，“I care”，“I think”）来描述常规动作和观点，这在此语境中是合适的。 2. 条件从句：“if there’s a bin nearby”是第一条件句，展示了自然使用条件结构的能力。 3. 表示目的的不定式：“to follow”在“for others to follow”中展示了用不定式表达目的。

Sometimes I just ignore rubbish on the street, especially if I’m in a hurry or if it looks dirty. I think it’s the job of the cleaners to take care of it.

To be honest, I sometimes ignore rubbish on the street, especially if I’m rushing somewhere or if the rubbish looks really dirty or dangerous. In my mind, it’s usually the responsibility of city workers to deal with it.

1. 频率副词的使用：“sometimes” 表示说话者的习惯或倾向，这是英语口语中表达频率的自然方式。 2. 条件句的使用：“especially if I’m rushing somewhere or if the rubbish looks really dirty or dangerous” 使用 “if” 引入条件，使答案更加细致和具体。

If there’s a lot of rubbish, I might report it to the local authorities. I don’t always want to touch it myself, but I still want to help.

If I see a lot of rubbish in one place, I might report it to the local authorities. Some cities even have apps for reporting litter, which makes it easier to help out without having to touch it myself.

1. 第一条件句：“If I see a lot of rubbish in one place, I might report it...” 这使用第一条件句来谈论未来可能的行动，显示了语法的灵活性。 2. 关系从句：“which makes it easier to help out without having to touch it myself” 使用关系从句来补充有关应用程序的额外信息，使回答更复杂且自然。
