not nearly (=by no means，far from) 远不
例1: The food supply will not increase nearly enough to match this, which means that we are heading into a crisis in the matter of producing and marketing food.
注：1) this是指上面提到的“到21世纪初世界人口将增加到60亿或70亿”。2) 又如：There are not nearly enough people here to do the job.(这里的人手远远不够承担这项工作。)
to say nothing of
not to speak of
not to mention
这四个词组也意为 “更不用说”，也是一种追补的说法。但它们与much less和still less有所不同。这些词组可以随前一句的意思而定，即前一句是肯定，则追加的也是肯定意义；如果前一句是否定，则追加的是否定意义
例1：I could not agree to, much less participate in such proceedings.
例2：He knows little of mathematics, and still less of chemistry.
例3：I did not even see him, still less (= much less) shake hands with him.
例4：In old China, here was hardly any machine-building industry, to say nothing of an electronic industry.
例5：Sally takes singing and dancing lessons, to say nothing of swimming and tennis lessons.
例6：At that time they could not afford the ordinary comforts of life, not to speak of luxuries.
例7：They have three fine sons, not to speak of their two 1ovely daughters.
例8：I don‘t know algebra or geometry，not to mention calculus.
例9：A11 they have to do is press a button，and they can see plays, films, operas and shows of every kind, not to mention political discussions and the latest exciting football match.
例10：I can‘t add two and two, let alone do fractions.
注意：美国成语词典认为let alone只能用于追加的否定。但是，有的词典认为，该短语也可以引导追加的肯定。例如：There were five people in the car, let alone the luggage and the two dogs.
