Present Perfect Passive
（完成時的被動語態）
Part 1:
教學提示
一般來說，主動語態和被動語態的選用應根據具體的情況而定。下面幾種情況一般用被動語態。
1）不知道或沒有必要說明動作的執行者是誰。例如：
Such books have been written for children . (兒童編寫這類圖書了。)
2）強調動作的承受者，而不強調動作的執行者。例如：
All these products have been tested .（這些產品都經過測試了。)
3）動作的執行者很模糊。例如：
The letter has been opened .（這封信被人拆開了。)
4）有時為了禮貌的需要，避免說出動作的執行者。例如：
They have been told many times not to make noises .
（已經有人多次跟他們說別那么大聲了。)

知識補充：
酈道元：北魏著名地理學家、文學家，我國游記文學的開創者。他仕途坎坷，多次被下放和調任。基于需要和對地理的濃厚興趣，罷官期間，他開始了著書之路。他長期進行實地考察，尋訪歷史古跡，觀察水流地勢，走尋探訪各地的物產民俗、風土人情、歷史興衰和神話傳說。經過認真研究分析、大量引進歷史文獻，傾盡畢生心血，《水經注》得以現世。在地理方面，這本書被稱為中國古代最系統、最全面的綜合性地理著作。酈道元以他對自然山水的熱愛、淵博的知識、精彩的語言，生動形象的描寫了祖國大好河山的壯麗，《水經注》流芳萬世。
自三峽七百里中，兩岸連山，略無闕處。重巖疊嶂，隱天蔽日，自非亭午夜分，不見曦月。
至于夏水襄陵，沿溯阻絕。或王命急宣，有時朝發白帝，暮到江陵，其間千二百里，雖乘奔御風，不以疾也。　　
春冬之時，則素湍綠潭，回清倒影，絕巘多生怪柏，懸泉瀑布，飛漱其間，清榮峻茂，良多趣味。
每至晴初霜旦，林寒澗肅，常有高猿長嘯，屬引凄異，空谷傳響，哀轉久絕。
故漁者歌曰：“巴東三峽巫峽長，猿鳴三聲淚沾裳。”
（巘，讀音同眼，山的意思）
