Lesson3 Macro Polo 學案

you must drink a large quantity of water. 你必需喝大量的水。擴展：a large /great /huge quantity of 和quantities of 都表示“大量的，許多”，在句中用作定語，既可修飾可數名詞（復數），也可修飾不可數名詞，一般只用于肯定句中。如：a large quantity of young people are fans of the “super voice girls”. large quantities of waste water flow into the river without being done anything with. quantity 表示“數量”；quality 表示“質量”。如：without quantity there can be no quality. 沒有數量也就沒有質量。重難點句式講解和分析：1. why was the emperor impressed by marco?皇帝為什么對馬可印象很深？impress vt. 意為“留下印象，使銘記”，impress一般不用于進行時。常用結構為impress sb. by/with sth. 給某人留下……印象impress sth. on sb. 使某人牢記某事make an impression on sb. 給某人留下印象。the girl impressed her friends with her sense of humour. the manager was greatly impressed by his talent. the teacher impressed on us the value of honesty. the beautiful scenery here made a deep impression on him. 2. the walls were covered in gold and silver and the hall was so large it could easily seat 6000 people for dinner. 墻用黃金和白銀砌成，宮殿大到可以輕而易舉地容納6000人同時進餐。這是一個由and 連續的并列復合句，在第二個分句中，so large 后面省略了that，（that）it could easily seat 6000 people for dinner 是一個結果狀語從句。so …that …  表示“如此……以致……”。拓展：sit 為不及物動詞，意為“坐，坐下”。如：they seated the guests of honor first. 他們先安排貴賓入座。i was seated at the back of the classroom. 我坐在教室的后面。i saw some villagers sitting at the back of the classroom. i saw some villagers seated at the back of the classroom. 我看到一些村子里的人坐在教室后面。3. however, marco was lucky enough to meet another prisoner who enjoyed listening to his stories about china. 然而，馬可很幸運地遇到了另一個喜歡聽他講中國故事的囚徒。該句中的enough用作副詞修飾形容詞lucky. 當enough修飾形容詞或其他副詞時，必須置于被修飾詞之后，且常與不定式或for 短語連用。如：he didn’t work hard enough and failed the examination. the man was unfortunate enough to lose his new car. 那人把新車丟了，真夠倒霉的。the bird was lucky enough to escape being caught. 這只鳥很幸運，剛好沒被逮住。拓展（1）enough也可用作形容詞表示“足夠的”，當修飾名詞時，可置于名詞之前，也可置于名詞之后作定語。如：is there enough room/ room enough for three more men ?we have enough food/ food enough for everyone. （2）enough還可用作名詞，意為“足夠、充分（的東西）”。如：he couldn’t earn enough to keep a family of four. i have said enough to explain my views.
