E选项有个明显的错误
前一句主语是usage of spices, 后一句的they 指代的是spices, 按比较对象平行的准则的话,改成这样应该就没问题了?
In cooking, the usage of spices is in small quantities, whereas in medicinal usage *it is* in large quantities.
定位第一段costs per unit of output fall as plant size approaches "minimum efficient scale," &第二段but rather by the first to exploit the full potential of such plants.
a, passing这里是名词还是动名词??如果是作名词,前面需要加上the passing,而且passing有自己的名词形式,passage;allowing作伴随状语,逻辑主语也不可能是people,只能是法案; in 1999紧跟act,造成一种1999年的法案的感觉
b, in 1999修饰歧义同a, they的指代对象不清,前面的复数名词太多
c, 句子主干是proliferation led to the act, and it allows...这里it语法上指代proliferation,但是实际指代act
e, passed和allowing的逻辑主语是谁?如果是伴随状语,逻辑主语是proliferation,如果是修饰act,逻辑主语就是act,所以两个非谓语动词用逗号隔开,没有紧跟修饰对象,会有歧义
果因,从一个结果归结原因。可能是别的原因导致的这个结果,削弱了题目了归结的原因
