用法讲解

adv. (副词)
  1. therefore的意思是“因此,为此,所以”,是副词,引导结果、结局或结论,不能误作连词用。
  2. therefore可引出一个独立句,但不能连接两个句子,因此当therefore前没有and等连词时,前面须用分号。
  3. 连接副词therefore用于句首时后面无需逗号,若位于句中前面可加也可不加逗号。
  4. therefore也可用于推理,作“故…,由此得出”解。
adv. (副词)
therefore, accordingly, consequently, hence, so, then, thereupon, thus
  • 这组词的共同意思是“因此; 所以; 于是”,它们的区别是：
  • 1.so, then和thus是一般用词; accordingly, consequently, hence, therefore和thereupon是正式用词。
  • 2.so和then常用于简洁的日常谈话,语义较轻,只表示因果关系或逻辑顺序,而不一定表示严格的推论关系。
  • 3.accordingly, consequently, hence, therefore, thereupon和thus都表示因果关系。accordingly语气较缓和,常译为“于是”; consequently一般不强调因果间的必然联系,而只是根据逻辑推理得出的结果; hence表示合理的推断,指出原因及其必然结果,但更强调原因; therefore强调因果间的逻辑关系,多用于表示严密推理或精确论证的郑重场合,故常用在数学、逻辑学等领域; thereupon则指“作为…的结果”; thus的意思和hence, therefore相近,但更正式庄重。
  • 4.accordingly常位于(分句)句首或句中; consequently, hence常位于(分句)句首; so只用于分句句首; then常用于分句句首,有时用于句末; therefore和thereupon常用于(分句)句首,有时用于句中; thus常用于(分句)句首。
  • 5.consequently, hence, so, then, therefore和thereupon前有时可加and; accordingly前偶尔可加and; thus前一般不可加and。
  • 6.hence常引导省略句; thus还可跟现在分词短语表示结果或目的。
    • therefore, somehow
  • 两者含义并不相同:therefore的意思是“因此”,上文要交代原因或理由; somehow的意思是“反正”,上下文无需说明原因或理由。例如:
  • He is not honest; therefore I don't trust him.他不老实,因而我不信任他。
  • Somehow I don't trust him.反正我不信任他。
    • accordingly，consequently，hence，so，therefore，thus
  • 这些连接副词均有“因此，所以”之意。
  • accordingly书面用词，强调根据某种原因而得出的结果，其前可用冒号或分号，但不用逗号。
  • consequently正式用词，侧重符合逻辑的结果。
  • hence较正式用词，指接下来的东西是理所当然的必需的东西，但强调其重要性。
  • so用于比较随便的场合，口语中多用。
  • therefore通常指引出一个推断出的必然结论。
  • thus多用于书面语中，可与therefore换用。
