A thick growth of sunflowers （standing ten feet tall ,their brown heads drooped） over the fence with the weight of their seeds.
D stood ten feet tall,their brown heads drooping
这题为什么选D?STOOD 和 droop那个是谓语?这句话就看不懂分析不出成分啊.
According to experienced auto mechanics .it is a good idea to change a car's oil and filter（ regularly because doing so helps） reduce wear on the engine parts..
E.Regularly for the purpose to help
这题为什么不选E而是原句没有问题呢?

1.先看前面的,主语是 sunflowers,后面缺少谓语,这里应该用stood.
接着又出来了their brown heads ,这里已经换了主体了,从sunflowers换到了their heads,而且stood ten feet tall 和their brown heads之间没有任何连词,只有一个逗号,所以后面的不是句子,不能用真正的谓语,要做变换,这里用的是现在分词做伴随状语.如果逗号后面加一个连词也是可以的,就不用现在分词了.
2.因为because后面引导的是一个句子
doing so是动名词做主语,helps是谓语,后面的就好理解了吧,help （to） do sth.
for the purpose of sth或者of doing sth是常用的结构,没有for the purpose to do的噢.
