副詞-連詞

在句子開頭的連詞或副詞

(1)副詞修飾全句
Luckily, he didn't know my phone number; otherwise, he would bother me.
Incredibly, Helena got straight A in her school report this semester.
Interestingly, cats and dogs can hardly get along well in a house.
修飾全句經常使用的副詞有：
obviously，undoubtedly，apparently，fortunately，clearly，unfortunately，incredibly，luckily， without doubt， surprisingly，frighteningly
這些副詞大多數表示說話人對全句的見解，在乎思上相等與「It is ...形容詞 that ...」。
eg:
Obviously, he is nervous about the test.=It is obvious that he is nervous about the test.
Unfortunately, he tripped over and fell in the mud.=It is unfortunate that he tripped over and fell in the mud.
(2)強調副詞
Hurriedly, the man drew me a scratch map to show me the direction.
Dangerously, the drunkard sped down the street.
Slowly and gently, snowflakes were drifting down from the sky.
(3)副詞表示某一地域或某一領域
Geographically, Canada is the biggest country in the world.
Financially, she is independent, but emotionally she is dependent.

And, but, or, for, so, yet等並列連詞開頭
現今，除了很是正式嚴肅的寫做，以連詞開頭的句子如今已被接受
將這類連詞以鏈接副詞或者短語代替（例如，以in addition 代and, however 代but, alternatively 代 or, consequently 代so )
