2017考研英語(yǔ)語(yǔ)法小講：副詞性連接詞

　　副詞性連接詞

　　副詞性質(zhì)的連接詞不能象連詞一樣分句或主從復(fù)合句之間用逗號(hào)連接。也就是說(shuō)它們不能連接兩個(gè)分句或引導(dǎo)從句。它們引導(dǎo)的句子與前面的句子之間要用分號(hào)或句號(hào)，而它們與引導(dǎo)的句子之間往往用逗號(hào)。副詞性質(zhì)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(jìn)關(guān)系的，如in addition, what is more, furthermore,moreover等。注意in addition 與in addition to 的區(qū)別：inaddition 是副詞性質(zhì);而in addition to 是介詞性質(zhì)，后面必須接賓語(yǔ)。

　　3.表示轉(zhuǎn)折關(guān)系的，如 however, nevertheless, nonetheless, on thecontrary, in contrast, 等等。要注意不要把however 當(dāng)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.
