分析 Is it difficlut to learn physics?学习物理难吗?
解答 答案:Is it difficlut to learn physics?
首先结合提示词和标点符合明确所要组合的句子是一个疑问句,组合成的句子的句意是"学习物理难吗.",句子叙述一件事实,所以时态应该为一般现在时的,主语是it,所以be动词应该用is,It is+adj+to do sth表示做某事是怎么样的,一般疑问句把is提前.故答案为:Is it difficlut to learn physics?
点评 做连词成句这种类型的题,首先确定句子类型,如:陈述句、疑问句或感叹句等,然后根据所给单词,明确主语、谓语等句子成分,在确定句意的前提下结合语法知识组合句子.
