最高级:三者或者三者以上的人或物进行比较时,需要使用形容词的最高级。
结构:A + be + the 形容词最高级 + of / in + 比较范围。
注意:形容词最高级前面要加定冠词 the。
如:Jack is the tallest in our class. 杰克是我们班长得最高的。
或:Jack is the tallest of all the students. 杰克是所有学生中最高的。
Mary is the most beautiful in our class. 玛丽是我们班长得最漂亮的。
Mary is the most beautiful of all the girls. 玛丽是所有女孩子中最漂亮的。
