【22】 __________I accept that he is not perfect, I do actually like the person.
A. While

D. Unless
【解析22】A。考查while表示讓步的用法。連詞while除了表示時間“當…期間、和…同時”，和表示對比“而、卻”外，還可表示讓步“雖然、儘管”，與although相同，它引導的從句位於主句之前。句意是：儘管我承認他並不完美，但我的確喜歡這個人。此外，while還可表示條件“只要(=as long as)”：While there is life, there is hope.只要有生命就會有希望。
