Question

He made _____ experiments to prove his theory, and the number _____ added up to 600.

A．a large number of ;have

B．a great deal of; has

C．a great many; has

D．plenty of; have

Answer 1

C

试题分析：考查词组辨析和主谓一致：第一空experiments为可数名词，用a large number of（许多的，大量的）的修饰；第二空the number 为……的数目，做主语时是单数形式，因而用has。选C。
考点：
点评：同样是大量的： a large number of修饰可数名词复数， a great deal of修饰不可数名词，a great many修饰可数名词，plenty of修饰可数或不可数名词。
