15.Mary has enough clothes,so she ________buy any more.( )| A. | doesn't need | B. | need | C. | doesn't need to | D. | needs to |
分析 玛丽有足够的衣服,所以她不需要再买了.
解答 答案:C.考查助动词.句意"玛丽有足够的衣服,所以她不需要再买了.".根据"玛丽有足够的衣服",可知应该是"不需要再买了",not…any more不再,主语是she,一般现在时态,含有实义动词,变否定句在实义动词前用助动词doesn't,实义动词用原形,need to do sth需要做某事.答案是C.
点评 助动词,帮助实义动词构成否定句和一般疑问句的,要根据时态,人称等选择正确用法完成试题.
