質問: 文構造が分からないので解説をお願いします。
回答: A Maori MP was thrown out of a New Zealand parliament debate for performing a haka in protest at what he said were racist comments made by an opposition party leader. 出典は書いてくださいよ。 <文の構造> A Maori MP <主語> was thrown <述語動詞部分:受け身> out of a New Zealand parliament debate <場所の副詞句> for performing a haka <thrown out に対する理由・原因の副詞句> in protest ... <performing a haka に対する理由・原因の副詞句> <in protest ... の構造> in protest at 〜「〜に抗議して」 what he said were racists comments made by an opposition party leader <名詞節> この名詞節 what he said were racists comments made by an opposition party leader は、破格な表現です。 「元の文」は、 He said that the comments made by an opposition party leader were racists comments. ここから、 He called the comments made by an opposition party leader racists comments. さらに、 The comments made by an opposition party leader were what he called racists comments. ここから、 what he called(→ said)racists comments だけをまず取り出して、 さらに、 made by an opposition party leader まで修飾句としてくっつけちゃったのが、 what he said were racists comments made by an opposition party leader 文法的には変な文ですが、意味はわかる。
