一、可引導比較狀語從句并在從句中充當句子成分(主語、賓語、表語),為便于理解,有時可視為than后省略了what,如:
1、We don’t want to do more than is necessary. (than在從句中作主語)
2、The pain was almost more than he could bear. (than在從句中作賓語)
3、Life here is much easier than it used to be. (than在從句中作表語)
二、省略情況,有時than后面會省略主語和助動詞,如
He returned three days earlier than expected.=
He returned three days earlier than he was expected.
三、倒裝情況,than引導比較狀語從句時,從句語序通常不需倒裝,但在正式文體中,有時也可倒裝,如:
City dweller has a higher death rate than country people does.
=City dweller has a higher death rate than does country people.
四、根據需要,than后面可以直接加時間或條件狀語從句 ,這種情況也可以看成是省略類型,如:
You are a little fatter than when I saw you last year. =
You are a little fatter than you were when I saw you last year.
They work better together than if they are alone. =
They work better together than they do if they are alone.
五、含義區分:同質比較還是異質比較 。than 通常用于兩個不同的人或物在同一方面進行比較,但有時指的可能是對同一個人或物在兩個不同方面進行比較,此時只用于more...than...結構,而不能用 –er...than...的形式,這類結構通常可譯為“與其...不如...”“有...無...”。如:
He’s more fat than short. 翻譯為與其說他矮不如說他胖,不能譯成他比短更胖。(邏輯不通)
六、和否定詞(never,no, hardly等)連用,表示強調,通常帶有最高級含義,如:
I’ve never had a worse morning than today.
我哪一天早上也不像今天早上這樣倒霉。即:今天早上最倒霉了。
若意思明確,有時可省略than結構。如:
I’ve never found a better job.
這是我找到的最好的工作。
