主語多樣
1. 她突然想到了一個主意。
She suddenly had an idea.
通常情況下，考生會馬上對這句話進行翻譯，基本不會動句子結構。但是以人作爲主語的英語句子總是不能夠很吸引人，所以這個句子如果稍微做下修改，以後面的賓語“主意”做主語，這個句子會發生一些變化。來源:考試大-托福考試An idea suddenly occurred to her.
2. 他開車心不在焉，幾乎闖禍。
He was absent-minded when driving, and almost caused an accident.
這句話依然是拿人做主語，稍微改一下，把心不在焉這個形容詞的名詞形式做主語，會大不相同。
His absence of mind during driving nearly caused an accident.
3. 美利堅合衆國創立於1789年。
The United States of America was founded in 1789.
這句話沒有任何錯誤，但是不夠多樣，可以用時間作主語。
The year 1789 witnessed the founding of the United States of America.
