问几道问题~求个解谢谢大家~
As its sales of computer products have surpassed
those of measuring instruments, the company has
become increasingly willing to compete for the mass
market salest  （it would in the past have conceded to rivals ）这个句子是对的。。我就是想知道括号it开始的这个部分是不是同位语啊？还是什么。。。~
Retail sales rose 0.8 of 1 percent in August,
intensifying expectations         (    that personal spending in the July-September
quarter would more than double）
of the 1.4 percent growth rate in personal spending
for the previous quarter.
一样的。。（）括号为正确句子~我想问的是double 不是正确用法是double something of么。。。比如double number/size of...而不能直接double of 。。。。我记得看曼哈顿时出现的。。。与two times 直接加sth 不同。。。有点疑惑。。当然。。其他选项错的离谱所以只问下这个用法~
求回答哦~

lz你的問題描述有點亂，看得有點費勁...建議下次清晰一點哈;)

1、it不是同位語，是省略了that的定從，
it would in the past have conceded (that) to rivals

2、double/twice something，something要求是抽象的名詞，例如the size/the number/height etc.
