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：氣象學家關於天氣變化的預測是根據計算機模擬測試得出的。
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，一定要寫明什麼東西是根據計算機模擬測試得出的。這是因為「base on 」需要兩個賓語(語言學家稱其為雙賓動詞)。在上面這個例子中，計算機模擬測試是其中一個賓語，氣象學家關於氣候變化的預測是另一個賓語。

EX: We based our analysis solely on information provided by Mr Andreas Schmitt in his e-mail of last Friday.
例句：我們的分析純粹是基於安德烈亞斯•施密特先生上周五發來的電郵中所提供的信息得出的。
EX: As requested, we based Mr Kowalski’s contract on the Company’s global template employment contract for L2/L3 level employees.
例句：按照要求，我們根據公司給第二至第三等級職員的合同模板制定了科瓦爾斯基先生的合同。
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的被動態——based on，即A是基於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於消費者的無知和缺乏經驗而得出的。
In summary, there are two ways of using 「base on」 – active or passive.
總之，base on可以有兩種用法——主動和被動。
PS: There is no such phrase as 「on the base of」 or 「basing on」.
另外，沒有「on the base of」 或是「basing on」這種用法。
3.On the basis of
EX. On the basis of the documentation you sent us, we believe your claim has a good chance of success.
例句：根據你們送過來的文件我們覺得你們很有可能贏得申訴。
