Answer 1

the smallest
worst
the least
the most carefully
better
to learn
to finish
Travel(l)ing
dose take
这些题主要考的是形容词的比较级和最高级的应用
和to do 动词不定式和doing做主语的一些内容
楼主啊，您的那个last night 打错了。。

Answer 2

the smallest 三者中比较 用最高级
the worst 同上
the least “of all”暗示三者以上，同上用最高级
the most carefully 副词修饰listen 最高级无变化
better 两者中的比较用比较级
to learn / learning to+动词原形 动词不定式/进行时表动作
to finish/ finishing it take somebody sometime to do/doing something
Traveling 句首动词加ing变为动名词。
does take everyday 决定了时态是一般现在时，主语由it代替所以用does，，does后面的动词和情态动词一样用原形
