可以。形容词是修饰名词的,副词是修饰动词的。be前面是名词,所以be后面肯定是要跟形容词的。要明白be(am/is/are)是一个系词,系表结构sb+be+adj,最简单的就是you are great!<br>英语的“be”是个特殊动词;有些语言,如马来文等,并没有“be”这样的动词。<br>“Be”除了原形的“be”之外,还有另外七种形式:am,is,are,been,being,was,were.<br>在句子中,“be”可以是主动词(The Principal Verb)或助动词(The Auxiliary Verb)<br>例句对照<br>【当做主动词时,“be”在性质上属于接系动词(The Linking Verb),后面要有名词、形容词、地方副词或短语作补足语(The Complement)。】例如:<br>The man is a science teacher.<br>这个男子是一位科学教师。<br>Mary's new dresses arecolourful.<br>玛丽的新衣服色彩鲜艳。<br>I have been there before.<br>我以前去过那里。<br>My mother is in the kitchen now.<br>我妈妈现在在厨房里。<br>这四个都是陈述句,可以变成疑问句,方法简单,把主语和“be”或助动词对换位置即可:<br>Is the man a science teacher?<br>Are Mary's new dresses colourful?<br>Have I beenthere before?<br>Is mother in the kitchen now?<br>当“be”要在祈使句中出现时,陈述句可借助助动词“do”,否定句必须在前加上助动词“don't”,如:<br>Don't be silly!
