3.A:It was hot yesterday B:____
A.It was so B.So was it C.So it did D.So it was 我选了B

Answer 1

1 C也是错的,应该是Hard as diamond is,而不是hardly（几乎不）,这是as的复合结构,adj/adv/v./n.+as +主语+谓语,用的是一种倒装结构,意思是“尽管钻石很硬,但是用激光给它凿个洞还是很容易的”
A的意思是“我刚一坐下”,B要用Although diamond is hard
2 主语是第三人称单数啊,所以谓语动词用A （那个助理研究生）
3 D的意思是表示重复或强调,“确实是”,不倒装；B的意思是“它也是”,倒装的时候表示另一个不同的东西也一样,所以选D
