教學建議
教學教法：
進入高三下學期的學習，基本進入了全面備考狀態。北京特級教師張鐵城老師有如下建議：
1． 對近年高考題精耕細作，反對盲目的題海戰術。
2． 不要單純背詞匯表，要把詞匯與語法結合起來，要在具體語篇中記憶詞匯。
3． 要多讀多題材的閱讀文，特別是現代生活中的熱點問題。
4． 要增加聽力訓練的力度，充分利用高三課本資源。
詞語辨析：
1.By 1820 the population of New York had grown to about 125 000, making it the largest city in the USA．
making it the largest city in the USA是分詞短語作結果狀語。動詞make 意為“使成為”，接名詞或形容詞構成復合結構。如：
The bus was held up by the snowstorm, thus causing the delay．
Her husband died in the war, making her a widow with three children
2.In 1858 an area of poor housing, factories and farm buildings was torn down and Central Park was created, reaching from 59th Street to 110th Street and across three avenues．
1）tear（tore，tom）是動詞，意為“撕開，扯掉”。短語動詞 tear down，意為“撕下，拆毀”。如：
tear down a notice 撕下一張通知
tear down a dangerous wall 拆毀一道危墻
2）reach作“延伸”解。reaching from 59th Street. . . and across three avenues是現在分詞作定語，修飾Central Park，相當于一個定語從句。
①現在分詞作后置定語相當于限制性定語從句，表示主動的動作或動作正在進行。
Anyone swimming will be punished．
The road joining the two villages is very wide．連接這兩個村子的路非常寬。
③現在分詞的被動語態作后置定語（既表示被動，也表示動作正在進行）
The question being discussed is very important.
Do you know the boy being punished by our teacher?
3.In 1892 the age of mass arrival began, during which 15 million new people passed through Ellis into the USA. over a period of 62 years．
1）mass是名詞，意為“大量，大批”，mass arrival是名詞修飾名詞，mass作定語。英語中名詞修飾名詞是常有的現象。如：
head teacher班主任 express train快車
news broadcast 新聞廣播 welcome speech 歡迎詞
time table時間表 orange juice 橘子汁
press conference 記者招待會 research project研究計劃
power plant電廠 weather forecast天氣預報
2）pass through為固定短語，含義為“穿過，通過，路過”，其中 through既可當介詞用，也可當副詞用。如：
He passed through unspeakable difficulties.
Were just passing through on our way to Shanghai
4.now that，due to，because of，owing to，since，as
1）now that．作“既然”時相當于since．突出事實性，而as作“既然”語氣較弱。有時now that中的that可省去。如：
Now（that）you are well again，you can travel．你既然恢復了健康，就能夠旅行了。
2）due to作“由于，因為，應歸功于”時常作表語或跟在名詞后。如：
The flight was cancelled due to the storm．班機因暴風雨停航了。
3）because of“由于，因為”只能引導副詞短語，在句中作狀語或表語。如：
Lincoln is admired because of his leadership．林肯由于出色的領導而受到人們的贊賞。
4）owing to“由于，因為”常在現代英語中與 because of，due to換用。如：
Owing to unfavourable weather，I was unable to carry on with it．由于天氣不好。我不能把它進行下去。
