连词 连接词与词、句与句，不能单独用作句子成分。分：并列连词【连接词与词;连接句与句 】、 从属连词【连接句子和句子，组成状语从句】
连接词：and、but、yet(轻微转折：但、可、却）、or、so、for(因为：这个解释才是连词）
错误：I like English because my English teacher我喜欢我的英语老师 正确I like English because my English teacher is good
连接句子和句子 I like English because of my English teacher (介宾结构）
连接词是连接英文单词的词，如also，and等。英语有486,000个左右的单词，连接词却只有70个左右，它们总是非常高频率的出现在各类文章、对话、电邮等英语实际沟通中。
表示承接also，and，and then，too，in addition，furthermore，moreover，what's more, again，on top of that，another，first，second，third，fourth
时间顺序now，then，before，after，afterwards，earlier，later，immediately，soon，next，in a few days，gradually，suddenly，finally(但可感到这些词是副词，所以原词条对于"连接词"即连词是错误)
空间顺序near(to)，far(from)，in front of，behind，beside，beyond，above，below，to the right/left，around，outside
比较in the same way，just like，just as
转折but，still，yet，however，nevertheless，nonetheless，on the contrary，in spite of/ in spite of the fact that，even though，although，despite / despite the fact that
一方面，另一方面on the one hand，on the other hand，for one thing，for another
结果和原因because，since，so，as a result，therefore，then，furthermore，otherwise(as a result ,therefore, thus不是连词是副词，所以经常是放句首，用逗号与后面句子隔开)
目的for this reason，for this purpose，so that，in order to
强调in fact，indeed，surely，necessarily，certainly，without any doubt，truly，to repeat，above all，most important
解释说明for example，in fact，in this case，for actually， for instance
总结in a word，above all,，all in all，finally，at last，in conclusion，as I have shown，in another word，in brief，in short，in general，on the whole，as has been stated，last but not least,in addition
并列连词①同类性质的词、短语、分句【fanboys（for、and、nor、but、or、yet、so)、however、both…and、either…or、neither…or】；②组成并列句
条件状语从句if, unless, as [so] long as, in caseDo you mind if I open the window?我开窗你不介意吧?
Don’t come unless I telephone. 除非我打电话，否则你别来。
注意：条件状语从句 中通常用一般现在时表示将来意义，而不能直接用将来时态。不过有时表条件的 if后可能用will，但不是将来时态, 而是表意愿或委婉请求(will为情态词)
结果状语从句in order that, so that, in case, for fearHe raised his voice so that everyone could hear. 他提高了嗓音，以便每个人都能听见

比较状语从句than 、as…asShe was now happier than she had ever been. 现在她比过去任何时候都快活
名词从句的从属连词that, whether, ifHe replied that he was going by train. 他回答说他将坐火车去
注意：引导名词从句的从属连词主要有that, whether, if 等，它们用于引导主语、表语、宾语和同位语从句。
其中that 不仅没不充当句子成分，而且没有词义，在句子中只起连接作用；而 if, whether 虽不充当句子成分，但有词义，即表示“是否”
