It was fine yesterday so I ______ the trouble to carry my raincoat with me.| A．don’t need to take | B．mustn’t have taken | | C．didn’t need to take | D．needn’t have taken |

答案
| C |
解析
试题分析：考查need的用法：句意：昨天天很好，所以我不必费事带雨衣。因为是昨天的事情，用过去时，didn’t need to do，A项的时态错误，Bmustn’t不能用于+have done的结构，D。needn’t have done本不必做而做了。都不符合句意。选C。
点评："need"既可做实义动词又可做情态动词. need 当做实义动词时,后面的不定式必须加to,说明:need + n./ need to do sth，need 当做情态动词时,只能用于疑问句,否定句和条件句，说明:用原形后面只加do,否定形式为 need not，needn’t have done本不必做而做了。didn’t need to do过去不必做…. |
