连词和状语从句考情分析：从近五年考查情况来看，连词是每年的必考点，其中并列连词的基本用法是重要考点，对从属连词的考查一般结合状语从句来考查，状语从句的时态(主将从现)也是一个常考点。
2017年备考时应掌握好并列连词的基本用法，对从属连词的基本用法和状语从句的时态(主将从现)也应注意。
考点突破考点一: 并列连词的基本用法并列连词按作用可分为表示联合、转折、选择和因果等四大类。
1.表联合关系的并列连词常见的有：（1）and意为“和，又，而，并且”。
如:I like English and math.我喜欢英语和数学。
（2）not only...but also(but as well) 意为“不但……而且……”。
如：Not only my father but also my mother likes watching TV very much.不但我的爸爸，而且我的妈妈也非常喜欢看电视。
（3）as well as 意为“也”。
如：He needs a knife as well as a piece of paper.他需要一把小刀，也需要一张纸。
（4）either...or... 意为“或……或……；不是……就是……”。
either...or... 连接两个主语时，谓语动词的单复数和其邻近的词保持一致，即由or后面的词而定。
如：Either he or I am going to have a meeting.要么他，要么我将参加会议。
（5）neither...nor... 意为“既不……也不……”。
当此词组连接两个主语时，谓语动词的用法和either...or...的用法一样，由nor后面的词而定。
如：Neither the teacher nor the students are happy.老师和学生都不开心。
（6）both...and... 意为“既……又……”。
连接两个主语时，谓语动词用复数形式。
如：Both Mary and Lily are from America.玛丽和莉莉都来自美国。
2.转折连词常见的有：but，while(而)，yet，however(然而)。
如：He likes sports,but he only watches them on TV.他喜欢体育，但是只在电视上观看。
My sister was doing her homework while I was playing computer games.我的妹妹在做作业，而我在玩电脑游戏。
Both Mary and Lily are from America.玛丽和莉莉都来自美国。
3.选择连词常见的有：or，otherwise。
如：Would you like tea or coffee? 你要茶还是咖啡？Hurry up,otherwise we can't catch the bus.快点，否则我们赶不上车。
重要的句型：祈使句+or...=if you don't...，you'll... 意为“请……，否则……”。
如：Don't go out,or you will catch a cold.请不要出去，否则你会感冒的。
4.因果连词常见的有: for,so和therefore等。
其中for引导的句子不表示直接原因，而是用来附带解释或说明前一句的情况，只用在句中，前后两个句子用逗号隔开。
如：You'd better put on your sweater,for it's cold outside.你最好穿上毛衣，外面冷。
My father is waiting for me,so I have to go.爸爸在等我，所以我要走了。
It is going to rain,therefore we have to put off the match.要下雨了，因此我们不得不推迟比赛。
