题目内容：

Be lack of 和 lack
在一本书上看到lack作为动词和名词时的不同用法...
它引用一个错误的例子是
Many students are lack of independent learning skills because the education system spoon-feeds them.
我想问问如果改成这样行不行:
Many students lack independent learning skills because the education system spoon-feeds them.
如果行,究竟为甚麼必须用lack,而不能用be lack of?

修改而成的第二句可以.众所周知A of B结构中,A是核心词,B起修饰和限定作用.把第一句的修饰部分和从句去掉,主句变为many students are lack,许多学生是不足.这句话显然逻辑谬误.一个实意名词怎么能是一个抽象名次呢?...
