New or old？⇒Is the town library new or old？這是一個選擇疑問句，句中兩個并列的選擇成分用or連接。選擇疑問句的答語不能用yes或no來回答，而是從可供選擇的兩個選項中選出一個直接回答。
eg：—Whose bag is this，Sarah's or Vivian's？這是誰的包，薩拉的還是薇薇安的？
—It's Sarah's.是薩拉的。
單元語法補充
①終止性動詞也稱為非延續性動詞或瞬間動詞，這類動詞所表示的動作往往在“瞬間”就完成了，動作不能“持續”，可以用于完成時態，但在完成時態的句子中不能與表示一段時間的狀語連用。如：since two days ago，for two years等。如果要表示該動作的延續，就需要將其轉換為延續性動詞或表示狀態的詞。
eg：The film started two hours ago.電影是兩個小時前開始的。
→The film has been on for two hours.電影已經開始兩個小時了。
②常見的短暫性動詞和對應的延續性動詞或表示狀態的詞：
borrow/lend→keep；buy→have；finish/end→be over；begin/start→be on；open→be open；arrive/come/go/move/reach/get to→be in/be at/be here/be there；close→be closed；die→be dead；leave→be away (from)；go to school→be in school/be a student；get up→be up；fall asleep→be asleep；fall ill→be ill；lose→be lost；become→be；join→be in/be a member of ...；return/come back/get back→be back；join the army→be in the army/be a soldier；get to know→know；receive/get a letter→have a letter；catch/get a cold→have a cold
