問題: 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. 現在簡單式：答案使用現在簡單式（"I notice," "I usually pick it up," "I care," "I think"）來描述經常性的動作和觀點，這在此情境中是適當的。 2. 條件子句："if there’s a bin nearby" 是第一類條件句，顯示能自然使用條件結構。 3. 不定詞表示目的："to follow" 在 "for others to follow" 中展示使用不定詞表達目的。

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. 使用頻率副詞：「sometimes」顯示說話者的習慣或傾向，這是在口語英語中表達頻率的一種自然方式。 2. 使用條件從句：「especially if I’m rushing somewhere or if the rubbish looks really dirty or dangerous」使用「if」來引入條件，使回答更加微妙且具細節。

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. 第一條件句：「If I see a lot of rubbish in one place, I might report it...」這使用了第一條件句來談論未來可能的行動，展示了語法上的靈活性。 2. 關係子句：「which makes it easier to help out without having to touch it myself」使用關係子句來為應用程式添加額外資訊，使回答更複雜且自然。
