1. bath 和 bathe
bath 做名詞， bathe 做動(dòng)詞，這是美國(guó)人的用法颊咬。
英國(guó)人 bath? 即作名詞也作動(dòng)詞，并可作及物動(dòng)詞牡辽，常用于“給小孩洗澡”喳篇。
It's not necessary to bath your kids everyday.
另外，bath 指在浴缸中洗澡态辛，“淋浴” 則用 shower
2.? provide = providing? 假如麸澜，只要
這兩個(gè)詞，用法完全一樣奏黑，可以當(dāng)作一個(gè)詞炊邦，意為“假如，只要熟史，以...為條件”馁害， 作連詞，引導(dǎo)條件狀語(yǔ)從句蹂匹。
I do believe in people being able to do what they want to do, providing they're not hurting someone else.
Provided they are fit I see no reason why they shouldn't go on playing for another four or five years.
3.? 代詞出現(xiàn)在被代替名詞之前
通常碘菜，都是先出現(xiàn)名詞，再次提到該名詞時(shí)限寞，才用代詞來(lái)代替忍啸。但在英語(yǔ)中，也有先出現(xiàn)代詞昆烁，再出現(xiàn)被代替名詞的情況吊骤。例：
Although we cannot see it, there is air all around us. (it 代指 air)
Without the friction between their feet and the ground, people would not be able to walk. ( their 代指 people's )
