請仔細閱讀下列語篇，留意加粗的藍色詞的時態(tài)。為什么此句用了過去完成時，而彼句則用了一般過去時?　　

My friend, Andrew, had lived in a foreign country for many years before he returned to 　　England　　. He had often dreamed of retiring in 　　England　　 and had planned to settle down in the countryside. He had no sooner returned than he bought a house and went to live there. Almost immediately he began to complain about the weather, for it was often bitterly cold. After so many years of sunshine, Andrew got a shock. He acted as if he had never lived in 　　England　　 before. In the end, it was more than he could bear. He had hardly had time to settle down when he sold the house and left the countryside. The dream he had had for so many years ended there. Andrew made a big mistake because he had thought of everything except the weather.　　

我們以該語篇為例，進一步分析過去完成時的用法和含義：　　

首句My friend, Andrew, had lived in a foreign country for many years before he returned to England. 我朋友安德魯在回到英國之前，已在國外生活了多年。顯然，had lived 要早于returned. 　　

He had often dreamed of retiring in 　　England　　 and had planned to settle down in the countryside. 在這句話中，had dreamed和had planned這兩個動作的參照物也是returned, 都早于returned. 　　

在He had no sooner returned than he bought a house and went to live there.句子中， “had no sooner +過去分詞+than +一般過去時”這是一個常用句型。had returned跟bought似乎是同時發(fā)生，但也有先后，根據(jù)時態(tài)一看便知。　　

He acted as if he had never lived in England before.句中，had never lived屬于虛擬語氣。He had hardly had time to settle down when he sold the house and left the countryside.也是一個類似的句型。　　

在The dream he had had for so many years ended there.這個句子中，had had也有參照物ended, 夢想在先，結(jié)束在后。　　

最后一句Andrew made a big mistake because he had thought of everything except the weather. 不用說也明白，因果關(guān)系誰先誰后。所以，在because引導的原因從句中，其動作一定是早于主句中的動作的。
