base on, based on和on the basis of的用法很多人一直搞不清。
?
1.Base on
?
EX: Climatologists base their predictions about climate change on computer simulations.
例句：氣象學(xué)家關(guān)于天氣變化的預(yù)測(cè)是根據(jù)計(jì)算機(jī)模擬測(cè)試得出的。
?
If you use “base on” you must say WHAT climatologists base on computer simulations. This is because the verb “base on” requires two objects (it is what grammarians call a ditransitive verb). In the above example, computer simulations is one object, and their predictions about climate change is the other.
使用“base on”時(shí)，一定要寫明什么東西是根據(jù)計(jì)算機(jī)模擬測(cè)試得出的。這是因?yàn)椤癰ase on ”需要兩個(gè)賓語（語言學(xué)家稱其為雙賓動(dòng)詞）。在上面這個(gè)例子中，計(jì)算機(jī)模擬測(cè)試是其中一個(gè)賓語，氣象學(xué)家關(guān)于氣候變化的預(yù)測(cè)是另一個(gè)賓語。

2.Based on

You can also say that “something is based on something” – this is the passive.
我們也可以使用base on的被動(dòng)態(tài)——based on，即A是基于B而來的。
?
EX. It cannot be said that the actions are based on the consumer’s ignorance or lack of experience.
例句：我們不能說這些措施是基于消費(fèi)者的無知和缺乏經(jīng)驗(yàn)而得出的。
?
In summary, there are two ways of using “base on” – active or passive.
總之，base on可以有兩種用法——主動(dòng)和被動(dòng)。
