    連接副詞however所帶出來的子句是相反的資訊,符合本句的內容需要:雖然困難,但我們仍然得在時限內盡力完成。

    而therefore所帶出來的子句是同向的資訊,而且是前一子句的結果。本句不適用,因為困難不是努力的原因。

    He is poor; therefore, he works hard to succeed.

    邏輯有問題:沒有因果,不能用therefore

    He is poor; however, he works hard to succeed.

    邏輯有問題:他現在既然成功了,怎麼還窮呢?

    he works hard to succeed because he is poor.

    邏輯有問題:因為沒有因果關係。

    Although he is poor, he works very hard.的文法正確,語意符邏輯。

    那麼三句的語意都是通的嗎?

  • 8 年前

    He is poor therefore he works hard to succeed.

    he works hard to succeed because he is poor.

    therefore, because都做連接詞用,所以都對的

    He is poor; however, he works hard to succeed.

    ; however,是做副詞用,we must, however, ...

    因為用標點轉折,所以選用however,連接詞時不必用標點

    這一題與文法完全沒有關係

    只與所選擇的單字的認知有關係
