Lesson1:形容詞、副詞的比較級和最高級1/34Adj.adv.2/34用來修飾動詞、形容詞、其它副詞、全句或名詞詞組及句子詞。e.g.very,early,quickly,etc.Herunsfast.Todayisveryhot.Pleasereaditloudly.3/34用以修飾名詞，表示事物特征詞。e.g.long,tall,short，cheap,hungry,etc.普通來說，漢字意思是“……”詞是形容詞，而漢字意思是“……地”詞是副詞。4/34形容詞比較級用于二者（人或事物）之間比較，表示其中一個比另一個“更……”或“較……”，后面用連詞than連接另一個所比較人或事物。比如：1.Thatrulerislongerthanthisone.2.Maryisyoungerthanme(I).“A+be+形容詞比較級

+than+B”意思為“A比B更……”比較級用法：5/34①在含有連詞than比較級中，前后比較對象必須是同一范圍，即同類事物之間比較*比較應在同類事物中進行.②在比較級前面使用much，表示程度程度“強得多”。如：Awatermelonismuchbiggerthananapple.③very,quite普通只能修飾原級，不能修飾比較級。比較級注意6/34young-yonger-yongestold–older-oldest
