语法专项突破专题六连词用于连接单词、短语、从句或句子的词叫连词。

连词是虚词，在句中不能独立充当句子成分，只起连接作用。

考点一并列连词并列连词按其作用分为表示转折、因果、选择和并列四大类。

1．表示转折关系的并列连词常见的表示转折关系的并列连词有while，but，yet等，用来连接两个意思不同甚至相反的词、短语或分句。

I was born in Changsha while I grew up in Changchun.我出生在长沙，然而在长春长大。

He wants to go，but his sister wants to stay.他想走，但他妹妹想留下。

2．表示因果关系的并列连词常见的表示因果关系的并列连词有so，for。

It's raining now，so I have to stay at home.天在下雨所以我不得不待在家里。

I must be away for a week，for I'll fix the machine for a factory.我必须离开一周，因为要为一家工厂修机器。

3．表示选择关系的并列连词常见的表示选择关系的并列连词有：or，either...or，otherwise（要不然；否则）。

（1）or的用法①or意为“或”，表示一种选择。

Would you like tea or coffee?你想喝茶还是咖啡？②or用在“祈使句＋or...”结构中，其中or在此意为“否则”。

Study hard，or you won't pass the exam.努力学习，否则你就会通不过这次考试。

③or用在否定句中代替and表示并列关系。

The baby can't walk or speak.这个婴儿既不会走也不会说。

（2）either...or意为“不是……就是……；或者……或者……”，动词与邻近的主语保持一致，即采取“就近原则”。

(七)形容词和副词历年云南中考试题中形容词和副词是必考的知识点，分值通常在2～4分之间。

从命题形式来看，一般有单项选择、完形填空、词语运用等；其中对形容词和副词的句法功能、比较等级的用法及易混形容词和副词的辨析的考查又是重中之重。

预计2016年云南中考热点仍将集中在形容词和副词的词义辨析和比较等级的用法上。

形容词是用来修饰名词或不定代词，说明事物和人的性质和特征的一类词，在句子中用作定语、表语、宾语补足语；而副词用以修饰动词、形容词或其他副词，在句子中作状语、表语、补语和定语。

英语中的形容词和副词都有等级的变化。

❶形容词的位置形容词作定语通常前置，但在下列情况中后置：1．有些形容词只能作定语。

如：little(小的)，only(唯一的)，wooden(木质的)，elder(年长的)，woolen(羊毛质的)等及复合形容词man－made(人造的)，kind－hearted(好心的)，English－speaking(说英语的)，take－away(可以带走的)等。

2．有些形容词只能作表语。

如：alone(孤独的)，asleep(睡着的)，awake(醒着的)，alive(活着的)，well(健康的)，ill(病的)，frightened(害怕的)等。

3．有些形容词貌似副词。

如：friendly(友好的)，lively(生动的)，lonely(孤独的)等。

4．有些形容词与定冠词the连用，表示一类人或物。

如：We should respect the old and love the young.我们应该尊老爱幼。

It's not polite to laugh at the blind or the deaf.取笑盲人或聋人是不礼貌的。

5．enough修饰名词时既可以放在名词的前面，也可以放在其后面；然而，enough作状语修饰形容词或副词时，应该放在形容词或副词之后。

如：We have enough time(＝time enough)to finish the work.我们有足够的时间来完成这项工作。
