2022屆高考英語第一輪語法狀語從句專題教案
【例句觀察】
she is as tall as her mother.
她和她媽媽一樣高。
【結論1】 as… as 和……一樣……
she is not as healthy as her sister.
她不如她姐姐健康。
【結論2】 not as / so…as…不如……一樣……； 不和……一樣……
the boy is taller than his father.
這個男孩長得比他爸爸高。
【結論3】比較級＋than 比……更加……
【疑難】比較狀語從句通常會結合三個倍數的表達句型進行考查，如：a是b的三倍大有如下三種表達：
(1) a is twice bigger than b.
(2) a is three times as big as b.
(3) a is three times the size of b.
【疑難剖析】
1. a is倍數＋adj.的比較級 (larger, heavier, more 等)＋than b.
2. a is倍數＋as＋adj. 的原級( large, heavy / many, much)＋ as b
3. a is倍數＋the＋表比較內容的名詞(size, weight, area, width, length 等)of b.
注意：句型1的倍數比句型2、3的倍數少一倍。
