EVERY TIME 不好, 会有歧意. BECAME错.

every time哪不好了,跟未划线部分的every time很对应啊. 我就是因为这个误选了D, 当时认为D的became也可以将就,因为说的是过去每次人们会做出的举动.(当然如果前面用了became后面也应该用过去时,且描述规律一般用现在时)

米吐！！

singdeath

我认为D主要错在最后一个字they，跟未划线部分连起来读they forget them every time a new source。第一个they指people，第二个them指solar principles，指代不一。

其次就是became的时态问题，跟整个句子的一般现在时陈述客观事实的语态不一致。

同意这个代词指代不同！！
