形容詞有三個等級:原級、比較級、最高級?,F將其用法解碼如下:
Ⅰ. 一級解碼——原級的用法
形容詞的原級表示人或事物的特征、性質。句中只出現一個人或事物,沒有比較對象時,要用原級。例如:
I am tall. 我個子高。
Lily is a good student.莉莉是個好學生。
友情提示:
1.表示程度相同時,我們常用“as +形容詞的原級+ as”句型,意思是“和……一樣”。例如:
She is as pretty as her sister.她和她姐姐一樣漂亮。
2.表示程度不同時,我們常用“not as/so +形容詞的原級+ as”句型,意思是“不如”。例如:
It’s not so/as cold today as yesterday.今天不如昨天冷。
Ⅱ. 二級解碼——比較級用法
形容詞的比較級用于二者(人或事物)的比較。基本句型為:主語 + 系動詞 + 形容詞比較級 + than + 對比人或事物。例如:
She is taller than I.她比我個子高。
This cake is bigger than that one.這塊蛋糕比那塊大。
友情提示:
1.在比較級前可用much,a lot,a little,even,still等詞或短語修飾。例如:
My brother is much older than I.我哥哥比我大得多。
Japan is a little larger than Germany.日本比德國大一點。
2.避免與自身相比。例如:
他在班上是最高的。
誤: He is taller than any student in the class.
正: He is taller than any other student in the class.
3.被比較的對象必須是同一類的。例如:
在冬天,北京的天氣比廣州冷得多。
誤: In winter, the weather in Beijing
is much colder than Guangzhou.
正:In winter, the weather in Beijing is much colder than that in Guangzhou.
Ⅲ. 三級解碼——最高級用法
形容詞的最高級用于三者或三者以上(人或事物)的比較?;揪湫蜑椋褐髡Z + 系動詞 + the + 形容詞最高級 + (n.) + of/in…(表示范圍)。例如:
Autumn is the best season in Beijing.在北京,秋天是最好的季節。
Mary is the shortest of the three.瑪麗是三人中個子最矮的。
友情提示:
1.形容詞最高級前常常要用定冠詞,
但當形容詞最高級前有物主代詞修飾時,則不再用。例如:
Today is his busiest day.今天是他最忙的一天。
2.當用of/in短語表示最高級的比較范圍時,介詞of后的名詞或代詞與句中的主語是同一類;只說明是在某一特定范圍的比較時,用介詞in。例如:
My father is the tallest in my family. 在我家里,我父親最高。
He is the happiest of us.他是我們當中最幸福的。
