※ 引述《yuanz (rock your body)》之銘言：
: Laboratory rats and mice live up to 40 percent longer than usual when
: fed a diet {of at least 30 percent fewer caloriesthan that which they
: would normally eat, but that otherwise} contains all necessary vitamins
: and nutrients.
: a. of at least 30 percent fewer calories than that which they would
: normally eat, but that otherwise
: b. with at least 30 percent fewer calories than what they would
: normally eat though otherwise it
: c. that has at least 30 percent fewer of the calories that they would
: normally eat, but otherwise it
: d. that has at least 30 percent fewer calories than they would
: normally eat but that otherwise
: e. that has at least 30 percent fewer calories than that which they would
: normally eat, though that otherwise
: 想請問(一)A.E 中的than that which:
: 1.是正確用法嗎
錯，that指代diet（詳見第2點），你不能拿calories比diet
: 2.that如何判斷指代calories還是diet
that後面的which they would normally eat，人們不會吃calories而是吃diet
: (二)E的第2個that解答說無指代是為什麼呢?
正確選項的對等連接詞but連接兩形容詞子句that has...跟that otherwise contains..
因為平行，所以第二個that的指代對象很明確，就是跟他平行的第一個that的指代對象
但是E選項的though並不能做對等連接詞之用，而是開啟一個新的副詞子句
因為這時that不是跟前面的that作平行，自然也就不清楚其指代對象是否與前面that一致
