比较级的构成
1.“A + be +形容词比较级+ than + B”意思为“A比B更……”。如:This tree is taller than that one. 这棵树比那棵树高。注意: ①在含有连词than的比较级中,前后的比较对象必须是同一范畴,即同类事物之间的比较。②在比较级前面使用much,表示程度“强得多”。如:A watermelon is much bigger than an apple. ③ very, quite一般只能修饰原级,不能修饰比较级。 2.“比较级+ and + 比较级”或“more and more +原级”表示“越来越……”如:It es warmer and warmer when es. 春天来了,天气变得越来越暖和了。 It is getting cooler and cooler. 天气越来越凉爽。 The wind became more and more heavily. 风变得越来越大。 Our school is ing more and more beautiful. 我们的学校变得越来越美丽。 ,如果有两者供选择,前面的形容词要用比较级形式。如:Who is taller,Tim or Tom? 谁更高,Tim还是Tom? 4. “the +比较级……, the+比较级”,表示“越……越……”。 The more money you make, the more you spend. 钱你赚得越多,花得越多。 The sooner,the better. 越快越好。
