一、形容词
形容词用来修饰名词,说明事物或人的性质或特征。通常可将形容词分成性质形容词和叙述形容词两类,其位置不一定放在名词前面,有时也可放在后面。下面只介绍性质形容词。
直接说明事物的性质或特征的形容词,我们称之为性质形容词。它有比较级和最高级的变化,可以用程度副词修饰,在句中可作定语、表语或补语。如cold(冷的),happy(快乐的),tall(高的),beautiful(美丽的)等性质形容词在形容词中占大多数。eg:
She is a beautiful作定语 girl.她是个漂亮的女孩。
The girl is beautiful作表语.这个女孩很漂亮。
We'll do our best to make our city beautiful作宾语补足语.我们将尽力使我们的城市美丽。
二、特殊疑问句
1.特殊疑问句的定义及特殊疑问词
特殊疑问句就是对句中某一特定部分进行提问的疑问句,句首用特殊疑问词,句末用问号,一般读降调。特殊疑问词包括wh-开头的特殊疑问词,或how及以how开头的词组。它们分别是:who,whom,whose,which,what,when,where,why,how,how much,how many,how long,how soon,how often,how far等。
2.特殊疑问句的两种语序
(1)当疑问词作主语或主语的修饰语时,要用陈述句语序,即主语在前,谓语在后。eg:
Who is waiting for you?谁在等你?
(2)当疑问词不作主语时,要用疑问语序,即疑问词+一般疑问句?eg:
What animals do you like?你喜欢什么动物?
Where is the panda from?大熊猫来自哪里?
3.疑问副词why的用法
(1)疑问副词why引导的特殊疑问句是询问“为什么做某事;做某事的原因”,回答时一般用because引出句子。eg:
—Why does she do that?她为什么要那样做?
—Because she wants to help the person.因为她想帮助那个人。
【注意】 在一般现在时的句子中,why后面用do还是用does,取决于主语,如果主语是第三人称单数,用does,如果主语是非第三人称单数,用do。但无论用do还是用does,谓语动词都必须用原形。eg:
—Why do you study English hard?你为什么努力学习英语呢?
—Because I like it very much.因为我非常喜欢这门学科。
(2)why还可以用来向别人提出建议,其句型为“Why don't you+动词原形?或Why not+动词原形?”意为“为什么不……?”eg:
—Why don't you go to the zoo with us?
你为什么不和我们一起去动物园呢?
—Because I have a lot of work to do.
因为我有很多工作要做。
