句子為： "Over the last several years, big oil companies have used profits to purchase their own stock on the open market, have lifted share prices."

這個句子中在文法上不正確的部分是 (D) have lifted2。

解釋：

句子的結構問題：原句嘗試用逗號連接兩個獨立的動詞片語：「have used profits...」和「have lifted share prices」。這種用法在英文文法中稱為「逗號連接句」（comma splice），通常是不正確的。

正確的連接方式：

如果兩個動作是並列的，需要一個對等連接詞，例如："...on the open market, and have lifted share prices." (並且提高了股價) [這是根據英文文法知識，非來源直接提供]。
