问题 Vitamins and minerals such as iron, calcium, are another group of essential nutrients, though the body does not need ______ it does the macronutrients.
选项 A、as great a quantity of these as
B、as a great quantity of these as
C、as great a quantity of these than
D、so a great quantity of these as
答案 A
解析 as…as…表示“和……一样”，注意这种结构的词序为“as+a．+a(n)+n．+as”，与“too+a．+a(n)+n．”和“so+a．+a(n)+n．”结构类似，如：It’s too hot a day to work．(天热得无法工作。)根据句意，故A正确。
