5.He is very funny. He always makes his classmates _____.

Answer

1.the most serious

2.minute

3.teeth

4.less

5.laugh

【解析】

试题分析：

1.联系下文可知句意为：丽萨是我们中最严肃的一个。她几乎从来不笑。故填形容词最高级the most serious。注意多音节形容词的最高级借助于单词most构成，定冠词the不能省略。

2.结合语境可知我们乘公交车用大约25分钟到达学校。故填复数名词minutes。

3.联系下文可知此处指的是牙齿，three是复数，故填复数名词teeth。注意tooth的复数形式是不规则变化。

4.联系下文可知前文意思是少吃肉，故填little的比较级less，更少的。

5.联系上文他很有趣。可知他经常让同学们发笑。Make后接不带to的不定式，故填原形动词laugh。
