文法 – 倒置表現
引用: The Economist – Curbing the Asian Contagion
Along with Singapore they have all confirmed cases of local transmission. So has Vietnam, where 16 people have caught the disease and 10,000 have been quarantined
eg. Tom has a cold and so does his wife.
eg. Tom likes cheese and so does his wife.
eg. Tom plays football and so does his son.
通常は既に登場している動詞を do/does で受けますが do/does 以外だと have のみこの様な倒置表現が見受けられます。
eg. Tom has a cold and so has his wife.
= Tom has a cold and so does his wife.
正しこの用法の have は old fashioned であったり formal な表現となります。
因みに過去完了形の場合は寧ろ do/does は使えず have しか使えません。TODO: 半法助動詞
eg. She has got a car, so has he.
eg. x so does he.
