覚え方のコツ Memory Tip
becomes は原形 become の三人称単数現在形で、主語が he、she、it や単数名詞のとき語尾に -s を付ける。発音は /bɪˈkʌmz/ で、末尾は無声音 /s/ ではなく /z/。becomes cold、becomes a doctor、becomes clear のように、後ろに形容詞・名詞を置いて「新しい状態や役割に至る」と覚える。
Becomes is the third-person singular present form of become. Add -s when the subject is he, she, it, or a singular noun: water becomes ice, she becomes confident, and the situation becomes clear. The final -s is pronounced /z/, giving /bɪˈkʌmz/. Remember that the complement names the result of the change: an adjective describes a new condition, while a noun phrase identifies a new role or thing. Contrast becomes with is: is states a condition, whereas becomes emphasizes entering that condition.
例文

She becomes more confident with each public speaking experience she has.

becomes の語源・成り立ち Etymology
古英語「becuman」（やって来る、至る）から。接頭辞 be-（完全に）＋ cuman（来る）で「ある状態に至る」が原義。関連語: come, become。何かが「来て」ある状態に到達するイメージが「〜になる」という変化の意味につながった。
Becomes is formed regularly from become by adding the third-person singular present ending -s. Become comes from Old English becuman, meaning “to come, arrive, or come to be,” and combines be- with cuman, the ancestor of modern come. Its historical idea of arriving at a place developed into that of arriving at a new state. The final consonant of become causes the ending in becomes to be pronounced /z/.
