八年級英語上冊第三單元導學案（2016新版人教版）
若有修飾成分，如twice, three times, half, a quarter等，則須置于第一個as之前。例如：
your bag is twice as expensive as mine.你的袋子比我的貴一倍。（二）. “否定 + 比較級” 相當于最高級�！� wait until we get a satisfactory reply, will you?— i couldn't agree more. the idea sounds great to me.5. “a + 比較級 + 名詞（than...）” 結構常出現在以never構成的完成時態的動詞后面。how beautifully she sings！i have never heard a better voice.6. 倍數表示法：...times as + 形容詞原級 + as...；...times + 形容詞比較級 + than...；...times the + 性質名詞 + of...。the dining hall is three times as large as that one.the dining hall is three times larger than that one.the dining hall is three times the size of that one. （三）比較級應注意的問題1. 為了避免重復, 常用the one代替單數可數名詞, the ones, those 代替復數名詞, that 代替單數或不可數名詞。2. 當比較對象屬于同一范圍時，需使用other來排除自身，否則會造成與自身相比較的矛盾。canada is larger than any other country in north america.4. “no + 形容詞的比較級 + than”結構表達對兩者均否定。don't be proud so early. you are no better than me.5. 比較級前面可以用even, still, yet , any, much, rather, a little, a lot, by far等修飾語用以加強語氣或表示比較程度。to tell you the truth, my boyfriend is much older than me.
