整理 J 動詞や名詞の意味を広げる文法形式 教科書 p.96
The pattern expands the verb/noun meaning
接続：普通形・Nの + ようだ／普通形・N + みたいだ
like / seems. Compare or speculate; みたいだ is more informal.
注意 / Note：Check the subject, tense and tone of both clauses; Avoid translating word for word from Vietnamese.
比較 / Compare：Compare with similar samples in the same article to choose according to nuance and connection. Same 課: 〜かける／〜かけだ／〜きる／〜通す／〜出す／〜やすい／〜にくい／〜づらい／〜すぎる／〜がちだ／〜らしい／〜っぽい／〜だらけだ — these models are often mistaken for each other, read the 接続 line carefully and then decide.
