一个语法问题

tbs

OG 242
Even their most ardent champions concede(that no less than a technical or scientific breakthrough is necessary )before solar cells can meet the goal of providing one percent of the nation'senergy needs.
答案that a technical or scientific breakthrough is necessary
解释中说no less than could be dropped without loss of meaning
但是这是强调的语气呀,可以改的吗,我现在不知道什么时候强调的语气可以去掉的了,是要看具体的句意而定吗?请帮我分析一下,谢谢

这不能算是强调吧

chnp

虽然有强调的意思但语义重复。

tbs

为什么语义重复?不明白

猫猫头

它应该是比较necessary的吧，可是necessary没有比较级的呀

chnp

no less than直接翻译过来是不少于，necessary意思是必需的，既然是必需的，那肯定是不少于的了。不就多余了吗？
另外，no less than 是conj.意思是正如。这个意思在这句话里显然没有任何意思。

vincentsam

这是lzm语法中的一题，以供参考对比
No less an authority than Walter has reported that American never read a book.

a. no less an authority than
d. not less an authority than
e. an authority no less than

答案是a. 因为no less [U]a person/thing [/U]than 是表示强调，相当于that very important person/thing. 以上是原文解释。大家对比一下就清楚了
