242 Even their mose 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's energy needs.
正确答案把划线部分的no less than去掉了
不太明白的是，no less than是什么意思啊？
做这个题目的时候，担心是作者为加强语气所用的短语，没敢排除A。
怎么判断一个短语是needlessly还是为了加强语气呢？
谢谢：）

no less than “不少于”，表示强调好像只用：no less X than x ，大全534：No less an authority than Walter...我个人翻成：“恰恰是”。Longman上说nothing less than sth表强调，不知道no less than sth是否也强调。
对于强调的对不对，我的处理办法是，把它表强调的符号词从句子中拿掉，然后在其欲强调的词后面加一感叹号：
A technical or scientific breakthrough (！) is neccessary before solar cells can meet the goal of providing one percent of the nation's energy needs。
的确觉得感叹的不是应该强调的地方，所以判定为多余。
而No less an authority than Walter(！是Walter耶!～)...则比较通。

1. no less than 在GMAT中一定要当比较来用，要有明确的比较对象。
a) sth + be + no less + adj. + than sth. / no less adj. than sth. be sth. (倒装)
No less remarkable than the development of the compact disc has been the use of the new technology to revitalize, in better sound than was ever before possible, some of the classic recorded performances of the pre-LP era.
b) no less X1 than X2 be … (特殊的比较方式)
No less an authority than Walter Cronkite has reported that half of all Americans never read a book. 不仅仅是Walter Cronkite一家机构。。。
c) no less than + sth. + be necessary/required/needed… redundant的结构，因为直接去掉no less than也不会影响原意。(OG242)
d) 但如果 no less than + sth. + 其他动词，往往不是redundant.
如：No less than 45 people attended yesterday’s meeting. 不可改成 45 people attended ….

我觉得这个翻译不对，no less A than B 的意思应该在于强调B，而事实是只有B，没有其他的了
longman：The message came from no less a person than the prime minister.
used to emphasize that the person or thing you are talking about is important or impressive
看了上面的讨论我糊涂了，
The message came from no less a person than the prime minister.
这句话的意思是，这个消息只来自the prime minister。
还是，这个消息不仅仅来自the prime minister。
再看看这句话
No less an authority than Walter Cronkite has reported that half of all Americans never read a book.
“不仅仅是Walter Cronkite一家机构。。。”这个翻译对吗？：）
谢谢！：）
up!
请高手指教！：）

OG say : In D and E, the preposition "for" is less idiomatic than “of” in expressing necessity.
But Longman say :

a) sth + be + no less + adj. + than sth. / no less adj. than sth. be sth. (倒装)
No less remarkable than the development of the compact disc has been the use of the new technology to revitalize, in better sound than was ever before possible, some of the classic recorded performances of the pre-LP era.（比较级，修饰remarkable,放在句首倒装）
b) no less X1 than X2 be … (特殊的比较方式)
No less an authority than Walter Cronkite has reported that half of all Americans never read a book. 不仅仅是Walter Cronkite一家机构。。。（强调数字，多余一家机构，no less than是一个短语）
c) no less than + sth. + be necessary/required/needed… redundant的结构，因为直接去掉no less than也不会影响原意。(OG242)
d) 但如果 no less than + sth. + 其他动词，往往不是redundant.
如：No less than 45 people attended yesterday’s meeting. 不可改成 45 people attended ….（同样也是强调数字，no less than做短语）
感谢这位仁兄做的总结，这里补充几点：
no less than可以连用，做短语
no less than
a) used to emphasize that an amount or number is large
By 1977, the
b) used to emphasize that the person or thing you are talking about is important or impressive
The message came from no less a person than the prime minister.
从这句和251读出了一点阅读的感觉。
