Now that the forest was destroyed by a big fire, a large ________of trees ______ to be planted ...

B

第一空考查“大量的”不同表达，a large number of修饰可数名词， a large quantity of修饰可数或不可数名词， a large amount of修饰不可数名词， a large sum of修饰不可数名词，所以第一空排除CD项，第二空考查主谓一致，a large number of修饰可数名词，后面接复数的谓语，所以A也不对。a large quantity of修饰可数或不可数名词，谓语是根据quantity的数来定，所以a large quantity of trees后面接单数谓语。选B。
