问题补充：
of time and energy has been spent in investigating the murder.
A. A great deal
B. A good many
C. Large numbers
D. Large amounts
答案：
(答案→)A. A great deal
B. A good many
C. Large numbers
D. Large amounts
解析：考查形容词短语。a great deal of许多，大量，修饰不可数名词；a good many/large numbers of修饰可数名词复数形式；要特别注意large amounts of做主语的时候，谓语动词应该使用复数形式。故本题D项错误。另外本句中的time and energy属于不可数名词，排除BC项。故A正确。
