No, just a few. For example, most Canadians say news [nju:z], but Americans say [nu:z]. We mainly use American words, but we use quite a lot of British words too. We fill our cars with gas, which is American, but we turn on the tap which is British En

没有，只有少数差别。例如，大多数加拿大人把news读成（nju:z），但美国人却读成（nu:z）。我们主要使用美国英语词，但是也使用很多英国英语词汇。我们给汽车加“gas（汽油）”，这是美国英语，但是我们说开“tap（龙头）”，这是英国英语。
