よくある質問
まず最初にどの文の構造を学ぶべきですか？
最初はシンプルな文から始めましょう：主語ひとつ＋述語ひとつです。明確で完全な単文が書けるようになったら、等位接続詞を使った重文に進み、次にbecause・although・whenなどの従位接続詞を使った複文へ進みましょう。この順序で実際の英語ライティングのほとんどをカバーできます。
フレーズ（句）と節（クローズ）の違いは何ですか？
フレーズは主語と定形動詞の両方を持たない語のまとまりです。節は主語と定形動詞の両方を持ちます。独立節は文として単独で成立しますが、従属節は単独では成立しません。この区別を理解することは、より複雑な文を正しく構築する上で不可欠です。
ランオン・センテンス（文の連結ミス）を避けるにはどうすればよいですか？
ランオン・センテンスは、2つの独立した節が適切な句読点や接続詞なしに繋がれたときに発生します。ピリオドで2文に分ける、カンマ＋等位接続詞（but・so・andなど）を使う、セミコロンを使う、または一方の節を従属させることで修正できます。声に出して読むと、ある考えが終わり次が始まる場所を聞き取れます。
並列構造が重要な理由は何ですか？
並列構造は、リストや比較を読みやすくし、よりリズミカルにします。シリーズの要素が文法的に並列でない場合——名詞とジェルンド、不定詞と過去形が混在するなど——読者は無意識につまずきます。すべての要素を同じ文法形式に統一することは、文の明確さを高める最も手っ取り早い方法のひとつです。
文をより多様で興味深くするにはどうすればよいですか？
文の長さを混ぜましょう：短い文はインパクトを生み、長い文はアイデアを展開できます。文の書き出しも変えましょう：時には副詞で、時には分詞句で、時には時間節で始めます。強調には周期文を、描写には累積文を使いましょう。何より大切なのは、英語をたくさん読み、多様な文のパターンを自然に身につけることです。
