A shooting dead chickens at airplanes has proved helpful to demonstrate
B shooting dead chickens at airplanes has proved itself helpful as a demonstration of
C shooting dead chickens at airplanes proves itself helpful as demonstrating

答案是E,怎么排除其它几个呢?

Originally published in 1950, Some Tame Gazelle was Barbara Pym's first novel, but it does not read like an apprentice work.
A does not read like an apprentice work
B seems not to read as an apprentice work
C does not seem to read as an apprentice work would
D does not read like an apprentice work does
E reads unlike an apprentice work
关键是AE怎么区别?does not read like 和reads unlike在意思上有什么区别?

1、分词的持续动作性修饰在这里显得不太合理，因为它强调的是一种持续伴随状态，就是cannon一直在shooting着。对于D和E，存在两个差异，一时时态，二是helpful in还是to。对于时态我的一般做法是先看A选项中的时态，如果没有特别错误，先保留时态。对于helpful用in 更合适一些
2、read like是固定搭配，没有read unlike的说法，记住就行了

感谢braveMBA的解题思路，没想到对时态的把握还有这样一个小窍门，非常感谢！

我是这样理解的，这个题目主要的区分应该是A/E.选E的主要原因是句子强调的是一件事情。其他的选项的错误主要集中在proved itself的itself上。
