单元语法专练
why引导的特殊疑问句
why作疑问副词,意为“为什么”,用来询问原因、理由,一般由“why+一般疑问句”构成其特殊疑问句式。由why引导的特殊疑问句,常用because引导的原因状语从句来回答。because是连词,意为“因为”,其后接句子来阐述原因或理由。例如:
—Why do you like English?你为什么喜欢英语?
—Because it’s interesting.因为它有趣。
注意:why还可以用于委婉地向别人提出建议,常用句型为“Why don’t you+动词原形+其他?/Why not+动词原形+其他?”意为“你为什么不……呢?”例如:
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作疑问副词,意为“在哪里”,用来询问地点,一般由“where+一般疑问句”构成其特殊疑问句式。例如:
—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:在疑问副词引导的特殊疑问句中,若句中有be动词,可直接将be动词放在疑问副词后构成疑问句;若句中有实义动词,则需要借助do或does放在疑问副词后构成疑问句。
形容词的用法
形容词常用来修饰名词或代词,表示人或事物的性质或状态等。当形容词作定语时,常用于修饰名词,且位于名词之前;当形容词作表语时,则需要放在系动词之后,构成“系表结构”。例如:
This is an old book.这是一本旧书。
He looks very happy.他看起来很高兴。
注意:当形容词作定语修饰something,anything等不定代词时,要放在不定代词的后面。例如:
There is something new in today’s newspaper.今天的报纸上有些新鲜事。
