英语口语：public transport是“公共交通”吗？
我们每个人都希望学英语时能“说”英语，能“用”英语，因此，如果你真的希望学英语时能“说”和“用”英语，你就不要把英语“说成”中文“公共交通、公共运输”。你这叫“学”英语却“用”中文。
如果我们真的想学英语时能“说”英语和“用”英语，我们就把英语public transport“说成”下面的英语：
1. Well,you know public transport is also called/is also known as public transportation, public transit, or mass transit.
把英语is also called/is also known as public transportation, public transit, or mass transit“说出来”、“用起来”。下面同理：
2.Well,city buses are (examples of )public transport, trolleybuses, trams (or light rail) are public transport,passenger trains are public transport.
3.Rapid transit ,also called metro,or subway,or underground are public transport.
4. Airplanes, coaches are public transport.
见到英语public transport必须要能“说”和“用”这些英语。现在你真的是在“说”英语和“用”英语了：把英语学成英语就是在练习英语口语。
