Part  One

Nominalization is common in academic writing in which the action is more important than the agent of the action . It can not only create an impersonal and objective tone , but make the writing more succinct and easier to read .  (P183)

名词化的好处：

简洁：把更多的信息“压缩”到一个精简的词语中，可以使一个句子能够表达更多的意思。

读者关注焦点转移：（语义重点转移）将表示具体行为或表示事物特点的形容词转化成为表示概念、观念、事实、现象的名词来表达。可以使读者关注的焦点从与主语相关的过程、动作、特点转移到事件、概念、现象、问题或事实本身。

Part Two 

Here is an extract from a biology report. Nominalisation has been used frequently in this passage, creating a more academic, abstract tone. 

Identify the norminailization  .

Many Australian plant species produce seeds with fleshy appendages  called elaiosomes. It was hypothesised that elaiosomes are involved in the dispersal of seeds by ants. To test this hypothesis, the removal of seeds with elaiosomes was compared to seeds from which the elaiosome had been removed and observations were made to confirm that the agents of seed removal were indeed ants. It was found that the removal of seeds with elaiosomes was significantly greater than those without elaiosomes. Observations of the seed removal process confirmed that ants were the only agents of seed removal.
