关于that的问题【OG20-P810-884题】

Kassy1998

Most of the county’s biggest daily newspapers had lower circulation in the six months from October 1995 through March 1996 than a similar period a year earlier.

A

a similar period

B

a similar period's

C

in a similar period

D

that in a similar period

E

that of a similar period

这道题我选了D选项，答案是C，说是D前后不平行，但我觉得that这里是起指代作用的，指代“circulation”那不是和前面的lower cir...in the six 平行了吗？

另外，曼哈顿语法里有一句例句：The MONEY spent by her parents is less than that spent by her children. 为什么这里than后面需要that呢？

深呼吸放放松

菜鸟认为:

化简： lower circulation in the six months  than ？
对比对象？ in the six months 和 than 后面的,那应该结构也和in the six months 差不多
完整句子：lower circulation in the six months  (%$#) than in a similar period ......



The circulation in the six months is lower than ?
对比对象？ Circulation对circulation
完整句子：
The circulation in the six months($$&&)  is lower than that ( the circulation) in a similar period ....
