发音与拼写Pronunciation & Spelling
Genuine matches: rain /reɪn/ pairs with lane /leɪn/ and vain /veɪn/; final -fall /fɔl/ pairs with fall /fɔl/, waterfall /ˈwɔtərˌfɔl/, and pitfall /ˈpɪtfɔl/. Beware lookalikes: in rainfall the -fall syllable is only lightly stressed, and not all -all words sound like fall (e.g., shall /ʃæl/).
