請教各位NN

這兩道題我實在不明白

何時應補出主詞 何時應補出動詞

請問是否有判斷的標準呢

請各位NN指教

兩題答案都是在這部分有點爭議的

我實在想不出來了說

第一题：选E无疑，第一个as many 修饰后面的名词，第二个as 自然要修饰名词，不能是D那样的省略主语的句子

第二题：不选B是因为那种形式the man-eater of the movies—fewer than have been 是idiomatic的吧（有人见过破折号这么用的吗？一般要补足两个吧，而且E补出了省略的代词要更precise and clear一些吧（不过这题形容词短语修饰远在天边的people也有些问题，不过既然ABCDE都是这样也只好随他去了

“何時應補出主詞 何時應補出動詞”说起来挺麻烦的，斑竹好像有做这方面的总结，自己去搜索一下，或者试试召唤斑竹大人现身帮忙吧。

ＭＭ不要着急，如果有明确的判断标准，就不会有对题目的争议了。

可参看一下

谢谢两位NN的帮忙 之前是参考了

但仍然无法为这两题下具体的结论

不过如版大的话 有结论就不会有争议了

希望我能选中ETS青睐的答案
