Answer 1

E项：错在句子成分残缺。 multyplying...sea是修饰plants的定语成分，你也可理解为tiny plants which multipliy in....sea 既然是定语，就可以忽略，所以简化后可以看到变成了 tiny plants turning the water green 根本不是一个完整句 所以E错
B项正确，multiply是动词此处意为繁殖 而turning the water green 逻辑主语是plants，没问题，表伴随着他们在这里繁殖，他们把水变成了绿色
这句话如果你读着别扭，顺序倒一下就好了
tiny plants muliply where the sea is usually rich in nutrients, turning the water green.
就是一个SVO,doing的形式。只不过把where...nutrients这个成分提前了

Answer 2

选B
你先看清楚这个句子的主语，是tiny plants，对应后面的一个伴随状语turning the water green.
B选项Where the sea is unusually rich in nutrients, tiny plants multiply作的是是地点状语。
然而你选择的E选项没有谓语啊~Tiny plants multiplying in the unusual nutritional richness of the sea 和turning the water green. 都没有谓语的成分~
你再看看B选项multiply则作谓语~
你看看还有什么不清楚的问题？

Answer 3

E选项 Tiny plants主语， multiplying 和后面的turning 都是现在分词形式的修饰成分，造成整个句子没有谓语动词，所以e错误
而b， 主谓= tiny plants mutiply,这就完整了 where......和后面的turning都是作为修饰成分
