单元语法小专题(Grammar Focus)
一、形容词
形容词修饰名词，用以说明事物或人的性质和特征。形容词是英语中最常用的一种词，它通常在句子中作定语、表语等。
1．形容词作定语
形容词作定语用来修饰名词或代词，放在名词或代词的前面。如：
This is an old book.这是一本旧书。
2．形容词作表语
形容词放在连系动词(be/feel/sound等)后，作表语，构成“主系表”结构，即“主语＋连系动词＋表语”，说明主语是什么或怎么样，即说明主语的特性。如：
The girl is beautiful.这个女孩很漂亮。
He looks happy today.今天他看起来很高兴。
二、特殊疑问句
1．特殊疑问句的定义及答语
2．特殊疑问词
特殊疑问词分为两类：疑问代词和疑问副词，其用法归纳如下：
词汇 | 用法 |
who | 意为“谁”，对主语(人称代词)进行提问 |
whom | 意为“谁”，对宾语(人称代词)进行提问 |
when | 意为“何时”，对时间进行提问 |
where | 意为“哪里”，对具体地点进行提问 |
how | 意为“怎样；如何”，对方式进行提问 |
why | 意为“为什么”，对原因进行提问 |
what | 意为“什么”，对某事物提问 |
which | 意为“哪个；哪些”，对具体或特指的事物进行提问 |
【注意】why引导的特殊疑问句一般要用because引导的句子来回答。because是连词，作“因为”讲，其后要接一个句子来陈述理由、原因。
