Section A(Grammar Focus­3c)　语法专讲 英语 七年级下册 人教版 原创新课堂 ►why引导的特殊疑问句 1．why为疑问副词，意为“为什么”。常用来询问原因、理由，一般由“why＋一般疑问句”构成其特殊疑问句。该句型常用because引导的状语从句来回答。because为连词，意为“因为”，其后要接原因状语从句。 eg：—Why do you like English？你为什么喜欢英语？ —Because it's interesting.因为它很有趣。 2．why还可以用来向别人委婉地提建议，常用句型为“Why don't you/not＋动词原形＋其他？”意为“你为什么不做……呢？” eg：Why don't you/Why not play soccer with us？你为什么不和我们一起踢足球呢？ ►where引导的特殊疑问句 where为疑问副词，意为“在哪里”，用来询问地点，一般由“where＋一般疑问句”构成其特殊疑问句。本单元where主要是和be/come from构成特殊疑问句。 eg：—Where are you from？(＝Where do you come from？)你来自哪里？ —I am from China.(＝I come from China.)我来自中国。 【注意】在此句型中，若句中有be动词时，就不能用任何助动词；但当句中是实义动词come时，其疑问句和否定句都要借助助动词do或does来完成。 2．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＋系动词＋表语”，说明主语是什么或怎么样，即说明主语的特性。 eg：The girl is beautiful.这个女孩很漂亮。 He looks happy today.今天他看起来很高兴。 3．形容词分类：身高体形——tall，short，fat，thin，heavy，strong，weak... 性格特征——shy，cute，outgoing，smart，friendly，helpful，mean，selfish... 感受想法——interesting，boring，relaxing，important，difficult，easy... 颜色质感——black，soft，smooth，hard，hairy，colorful... 一、单项填空。 ( )1.What a ________ boy！He worked out such a difficult math problem.
