　　13. From a heavy gun that was raised, the captain realized that the ship must havebeen a cruiser.

　　從撈起的一門大炮來看，船長認(rèn)為那艘船一定是艘巡洋艦。

　　語言點(diǎn):句子結(jié)構(gòu)分析:that was raised是定語從句，修飾gun。后面分句中的that引導(dǎo)賓語從句，交代realised的內(nèi)容。注意，must have been不表示對(duì)現(xiàn)在情況的推測，而是對(duì)過去情況的推測。

　　14. In another chest, which contained the belongings of a ship's officer, there was anunfinished letter which had been written on March 14th, 1943.

　　另一只海底沉箱中裝的是船上一位軍官的財(cái)物，其中有一封寫于1943年3月14日的信，但沒有寫完。

　　語言點(diǎn):句子結(jié)構(gòu)分析:第一個(gè)which引導(dǎo)非限制性定語從句，修飾chest。第二個(gè)which引導(dǎo)定語從句，修飾letter。

　　15. The captain learnt from the letter that the name of the lost ship was the Karen.

　　從這封信中船長了解到沉船船名是“卡倫”號(hào)。

　　語言點(diǎn):句子結(jié)構(gòu)分析:這句話的主體結(jié)構(gòu)是“learn from…+賓語從句”。
