发音与拼写Pronunciation & Spelling
No word here rhymes exactly with infiltrate (/ɪnˈfɪl.treɪt/). The -trate words penetrate, concentrate, and demonstrate share the spelling -trate and a similar final /treɪt/ or /streɪt/ sound, but their stressed syllables differ, so they are lookalikes rather than true rhymes. Filter and filtration are related lookalikes but sound clearly different.
