eg. 1) a little bigger 大一點兒
2)much more 多得多
3)even heavier更重
但注意:不能在比較級前加so; too; very; quite等。
2.比較級必須是同類事物相比(即as; than后的詞應(yīng)與主語是同類事物),注意常用漏的代詞有:that; those; one; ones
eg. 1)The apples (A) in this basket (B) are redder (C) than in that basket(D). _________
2)This knife (A) isn’t (B) so (C) new as that (D). _______________
3)Our classroom (A) is (B) bigger (C) than Lily(D). _______________
3.個體與整體相比,不能包括個體,常用“any other + 單數(shù)名詞”來進(jìn)行比較。
eg.1)Betty(是個體) is cleverer than any student in her class(是整體). ( × )
正:Betty is cleverer than any other student in her class.
=Betty is cleverer than anybody else in her class.
=Betty is the cleverest in her class.
(特別注意以上三種句型的轉(zhuǎn)換)
2)China is bigger than any country in Africa.
中國比非洲的任何一個國家都大。
3) China is bigger than any other country in Asia. 中國比亞洲的任何一個其他國家大。
*4.使用最高級時應(yīng)把主語包括在范圍內(nèi)。
eg. Mary is the tallest of all her sisters.( × )
(all her sisters已排除了Mary)
改:Mary is the tallest of all the sisters.
5.表示“第二、第三……”時,可在最高級前加“second , third, …”(但“第一”不能用first)
eg. The Changjiang River is the first longest river in China. 改錯:________________
