解析
试题分析: 根据句意:我没有必要向索菲亚寻求帮助,因为我自己管理的非常好。可知,表达没必要英语中有don’t have to, don’t need to, needn’t本题中时态可知为一般过去时,故选C 点评:need可作为情态动词和实义动词用,need用法如下: 一、作情态动词 1.need作情态动词无人称或数的变化, 后接动词原形,多用于否定句和疑问句中。如:You needn"t worry.你不必担心。 2.由need引出的一般疑问句,肯定回答常用must或have to;否定答语常用needn"t. 如: —Need I answer the question? 我需要回答那个问题吗? —Yes, you must. /Yes, you have to.是的,你必须回答。/是的,你得回答。/No, you needn"t.不,不必了。 3.由must引出的一般疑问句,肯定回答用must,否定答语用needn"t或don"t have to。如: —Must I do the work now? 我必须现在干这个活吗? —Yes, you must /have to.是的,你必须做。/No, you needn"t /don"t have to. 不,你现在不必做。 二、作行为动词 need 作为行为动词有人称和数的变化, 后面可接名词、代词、动名词及带to 的动词不定式;可用于肯定句、疑问句和否定句中,如:She needs help.她需要帮助。I don"t need to see the doctor.我不需要看病。—Do you need to go at once? 你需要马上走吗? —Yes, I do.是的,我得马上去。 —No, I don"t.不,不用马上走。 |
