标题: OG46-比较句中助动词何时需补齐

各位大虾，有关OG46的两个语法点不清楚，可否帮忙解释，谢谢！

46. A study commissioned by the Department of Agriculture showed that if calves exercise and associated with other calves, they will require less medication and gain weight quicker than do those raised in confinement.

(E) associate with other calves, they require less medication and gain weight more quickly than

1。为什么“require"及“gain"不用将来时，不是应该“X will happen if y happens(OG37)"

2。为什么”than"后不用补齐助动词"do"，但在OG12及OG19中都补齐了？

可否告之何种情况下需补齐助动词。

E rice has a protein higher in quality than
