连词要连接两个对等成分,比较连词than当然也不例外.
1、minority graduates are nearly four times more likely than are other graduates是两个句子在比较.第一个句子是minority graduates are more likely,第二个句子是other graduates are likely.第二句中的表语形容词likely因在第一句已有,可以省去,以减少笔墨；但谓语动词are不能再省,否则句子将无法成立 .
2、 Plants are more efficient at acquiring carbon than are fungi也是两个句子在比较.第一个句子是Plants are more efficient,第二个句子是fungi are efficient.同样,第二句中的表语形容词efficient因在第一句中已有,可以省去,以减少笔墨；但谓语动词are不能再省,否则句子将无法成立.
3、over the age of thirty than under it是两个介词短语在比较,不牵扯be动词问题.
