人教版六年级英语时态转换练习题30题【含答案解析】1. I often go to school by bike. But yesterday I _____ to school on foot.A.goB.wentC.goes答案解析：B。
一般现在时中，“I often go to school by bike”表示经常发生的动作，用动词原形go。
一般过去时中，yesterday 是过去的时间标志，动词要用过去式went。
goes 是第三人称单数形式，不符合此语境。
2. She usually has breakfast at 7:00. But this morning she _____ breakfast at 7:30.A.haveB.hadC.has答案解析：B。
usually 表明一般现在时，has 是have 的第三人称单数形式。
this morning 是过去的时间标志，要用一般过去时，have 的过去式是had。
3. We _____ football every Sunday. But last Sunday we _____ basketball.A.play;playedB.played;playC.play;play答案解析：A。
every Sunday 是一般现在时的标志，we 是第一人称复数，用动词原形play。
last Sunday 是过去的时间标志，用过去式played。
4. My father often _____ newspapers in the evening. But yesterday evening he _____ a book.A.reads;readB.read;readsC.reads;reads答案解析：A。
often 表明一般现在时，father 是第三人称单数，read 的第三人称单数形式是reads。
yesterday evening 是过去的时间标志，read 的过去式还是read。
A、一般现在时定义一般现在时。
表示通常性、规律性、习惯性的状态或者动作（有时间规律发生的事件）的一种时间状态。
基本结构构成1. be动词属于系动词, 表示事物和人的状态。
在一般现在时态的句子中主要表现为三种形式：am ，is、are。
后面往往接形容词或名词做表语。
如：(1)I’m strong. (strong形容词做表语)(2)He is a boy.( a boy名词做表语)含有be动词的句子在进行否定、疑问句变化时，都要在be动词上变化。
(1)变为否定句：主语+be+ not+其他。
即，直接在be后not.①I’m not a Chinese girl.②You are not right.③He is not strict with me.(2)变为一般疑问句：Be+主语+其他？即把be动词提到主语的前面。
注意：当肯定句主语为第一人称I和We时，变一般疑问句要变为第二人称，be动词也要相应的变为are.同样肯定句中的my和our 也要变为your.①I am a worker. (变为一般疑问句)→Are you a worker?②We are good friends. (变为一般疑问句)→Are you good friends?③She is from Japan. (变为一般疑问句)→Is she from Japan?(3)变特殊疑问句：一般的要求为“对划线部分提问”，即用特殊疑问词代替划线的部分，后接省略划线部分的一般疑问句（一般不再出现划线部分）。
如：①I’m well.（对划线部分提问）→How are you?②She is from America. （对划线部分提问）→Where is she from?2、情态动词：can,may,must,need为情态动词地一般现在时，need有时还做实义动词用。
我们这里主要以can为例来说明情态动词的用法。
情态动词后面必须接动词的原形。
