助动词后面省略的词一定要是原文前出现过的

精炼厂现在每桶原油比以前多付5欧元
og93
13.The prhase 55percent more delay is not as clear as phrase a 55 percent increase in delays og94
Mahattan:In many cases, when we have one noun modified by a prepositional phrase, we can turn the phrase into a Noun-Adjective and put it in front of the first noun, thus shortening the whole expression.
This process works the best
when the preposition is of ,the simplest and most common preposition in English. However,
if the preposition is not of, then you should avoid collapsing the prepositional phrase.
Notice that
places or locations rarely work well as Noun-Adjectives, unless the original prepositional phrase begins with of
14关于although的用法 og95
Although 引导的是一个dependent clause，也就是说它引导的是一种不能脱离主句的从句
15.同时用even though和but显得 redundant和nonsesial
有道背了400个单词，真的很好，有些反复记忆印象很深刻~~
