【聚焦语法】
形容词比较级
形容词比较级用来对两者（两个人或两个事物）进行比较。
1. 当句子中有标志词than，表示前后两者之间的比较。如：
Allen is stronger than you. 艾伦比你更强壮。
Some dinosaurs are smaller than our schoolbags. 一些恐龙比我们的书包还小。
2. 在两者之间选择“哪一个更……”时，常会用到句型“Which/Who is +比较级，A or B ”。如：2·1·c·n·j·y
Which sweater is ( http: / / www.21cnjy.com )cheaper, the red one or the yellow one 红色的和黄色的运动衫，哪个更便宜？【来源：21·世纪·教育·网】
Who is thinner, Mary or Amy 玛丽和艾米谁更瘦呢？
3. 结合具体语境来判定使用形容词比较级。如：
Spring is coming! The ( http: / / www.21cnjy.com )sky is clearer and the sun is brighter. 春天来了！天空更清澈，太阳更明亮。21·世纪*教育网
