It seems that there arepeople out of work. Something must be done to solve the problem.
A. a great many
B. a great many of
C. a great deal
D. a great deal of
答案：
(答案→)A. a great many
B. a great many of
C. a great deal
D. a great deal of
解析：考查形容词短语。表示许多的词组有：a great deal of(修饰不可数名词)；a great many修饰可数名词复数形式。A great deal许多，大量（做状语，修饰副词）；B项多了一个of；本题使用a great many修饰可数名词复数形式。句意：似乎有很多人失业了。一定要采取措施来解决这个问题。
