分詞構文

作り方は下記。
1.従属節の動詞を現在分詞へ変換
2.接続詞を消す
3.従属節の主語を消す。

現在分詞を使った分詞構文。
例文:When I ate breakfast, I chipped my teeth.→ Eating breakfast, I chipped my teeth .
歯toothは複数形になると、teethです。

過去分詞を使った分詞構文。
例文:While the report was supported by many readers, people didn't buy the report .
→Supported by many readers, people didn't buy the report .

従属節の時制が主節の時制よりも過去の場合の分詞構文。
While the report was supported by many readers, people don't buy the report .
→Having been Supported by many readers, people don't buy the report .
Having beenは省略されることもある。
