是情态动词can的过去式形式，表示过去的能力。它没有人称和数的变化，后面接动词原形。变否定句在could后加not,变一般疑问句把could提前。这个男孩七岁时就会骑自行车。Theboycouldrideabikewhenhewasseven.前年你会讲日语吗？CouldyouspeakJapanesetheyearbeforelastyear?Practise

【注意】在某些情况下，could

并不表示过去，只是表示委婉、客气的语气。其肯定答语用：Sure./Certainly./All

right.等。否定答语用：Sorry./Sorry,Ican’t.等。A:Couldyoutellmeifheisastudent?

我们必须想出一个计划。need是一个常见的动词，表示“需要”之意。它既可以作实义动词，也可以作情态动词。其具体用法如下：这个人在工作时需要一本英语词典。ThemanneedsanEnglishdictionarywhenheworks.你必需亲自见他吗？Doyouneedtoseehimyourself?1)need用作实义动词，有“必要”、“必需”之意，有人称、数和时态的变化，可以接名词、代词、动名词或带to的动词不定式作宾语，构成疑问句和否定句时要借助于助动词。Practise你必须和你的同学去公园吗？Needyougototheparkwithyourclassmate?他不必花掉这么多钱买这块新手表。Heneedn’tspendmuchmoneyforthisnewwatch.2)need用作情态动词，意为“必须”、“必要”，没有人称、数等变化，后接不带to的动词不定式。通常用于疑问句和否定句中，构成疑问句和否定句时，不需要使用助动词。PractiseA:NeedIcometoworktomorrow?

明天我需要来上班吗?B:Yes,youmust/haveto.
