副詞性連接詞
副詞性質的連接詞不能象連詞一樣分句或主從複合句之間用逗號連接。也就是説它們不能連接兩個分句或引導從句。它們引導的句子與前面的句子之間要用分號或句號,而它們與引導的句子之間往往用逗號。副詞性質的連接詞在寫作中常常使用,主要分為以下幾類:
1.表示順序的',如first, in the first place, then, finally, inthe end等等。尤其要注意then. 如:
誤:He graduated from college in 2003, then hefound a job.
正:He graduated from college in 2003, and thenhe found a job.
Hegraduated from college in 2003. Then he found a job.
2.表示遞進關係的,如in addition, what is more, furthermore,moreover等。注意in addition 與in addition to 的區別:inaddition 是副詞性質;而in addition to 是介詞性質,後面必須接賓語。
3.表示轉折關係的,如 however, nevertheless, nonetheless, on thecontrary, in contrast, 等等。要注意不要把however 當成連詞:
誤:In 2003, the United States launched the waron Iraq on account of Iraq possessing weapons of mass destruction (WMD),however, no WMD has been found in Iraq so far.
正:In 2003, the United States launched the waron Iraq on account of Iraq possessing weapons of mass destruction(WMD). However, no WMD has been found inIraqso far.
