2 请教based on的用法
看到一句话:
One of greatest benefits of wealth is it will allow you to improve these based on your personal needs and long term benefits.
我认为这句话中based on…后面部分是做状语修饰前面动词improve。我看在其他语句中，based on和这句话一样，即使没有表达被动语气也是使用过去分词形式作状语，请解释一下这样表达方式的原因。

的确是 based on 作状语，修饰 improve。美国 GMAT 考试认为 based on 作状语是错误用法，建议改为 on the basis of。查各英英词典，没见到 based on 作状语用法。Our plan is based on an upturn in the economy. 这时的 based 是被动语态。
但现实中，based on 作状语的例子比比皆是。所以，按曲鼎老师的谆谆教导，“照本宣科”是不对的，要有包容心态对待新事物、新现象。
陈用仪在《英语常用词疑难用法手册》的解释，也可供你参考。他认为 be 后的 based on 是形容词短语，这和所有英英词典的说法相悖：
【本来based是由动词过去分词转变成的形容词，应该依附于某一个名词。【例如】His opinions are based entirely on prejudices. 他的意见完全是基于偏见。但是用多了，往往游离于任何名词之外，成了句子中的一个副词，引入一个状语成分，管句中的动词，而不管近处的名词。【例如】(They) insist such a (DNA) databank must come with guarantees that no one be denied employment or insurance based on genetic makeup. (US News & World Report, Dec. 2, 2002, p. 60) 他们坚持主张，如果建立DNA数据库，就必须同时作出保证，对任何人都不得根据其基因结构而拒绝录用或拒绝承保（based on同前面的employment or insurance没有修饰关系，是修饰deny的状语）。/ What has changed radically in recent years is the view that cancers of different types—breast, lung, colon—are relatively homogeneous based on how they look under the microscope and how far they have burrowed into the body. (US News & World Report, Nov. 3-10, 2008, p. 46) 近年来发生了根本变化的，是原先的那个看法，认为各种不同类型的癌症，如乳腺癌、肺癌、结肠癌，按照显微镜下看到的形状以及钻入身体多深来看，似乎是比较同构的。/... accepting students based purely on merit, without regard to wealth,... (Jonathan D. Glater, The New York Times, June 10, 2009) …不问家庭经济情况，单纯按照优劣录取新生…/ ... my hearing must also be fading fast based on the increased volume directed at me. …从人家对我说话时加大了声门看来，我的听力一定是在迅速退化。类似这种情况（即形容词作副词）的，还有relative to，effective, compared to等，均各另见。】
