一般现在时态与一般过去时态的区别 一般现在时的概念： 1. (1)表示经常性或习惯性的动作或存在的状态。 如：I often go to school by bike. (2)表示客观事实或普遍真理。 如：The earth goes around the sun. (3)在时间、条件等状语从句中，用现在时表示将来。 如：If it rain tomorrow, we won’t go to the park . When I grow up ,I will go to America. (4)在某些以here ,there 开头的句子中用一般现在时表示正在发生的动作。 如：There goes the bell. 铃响了。 与一般现在时连用的时间状语 (1)表示频度的副词 always , often ,usually, sometimes 等。 （2）on Sundays , on Monday afternoon, every day , in the morning, every year 等时间状语。 （3）once a year, twice a month , three times a week 之类的表示频率的词组。 一般现在时的构成 其主要用“系动词be”和“实义动词”表示，如果主语是第三人称单数则将动词原形变为第三人称单数形式。 一般过去时的概念： （1）表示过去某时间发生的动作或存在的状态。 如：I got up at six this morning . We visited the factory last week. (2)表示过去的习惯或经常发生的动作。（过去常常做某事也可用used to do sth 来表示） 如：When I was in the country side , I often swam in the river. 与一般过去时连用的时间状语 last night , last week ,yesterday, yesterday morning/ afternoon/ evening, some years ago , in 1995, in the past , the other day, at that time , just now, after two days 等。 一般过去时的构成 类别 构成方法 例词 读音规则 一般情况 加-ed look--looked play--played start -- started 清辅音后面读作/t/；浊辅音和元音后面读作/d/；/t/和 /d/后面读作/id/ 。 以e 结尾的动词 加-d live-lived hope--hoped use--used 以重读闭音节结尾的动词，末尾只有一个辅音字母 双写这个辅音字母，再加--ed Stop--stopped Plan--planned 以辅音字母加y结尾的动词 变y 为i，再加--ed study--studied carry--carried worry--worried 其主要用动词的过去式表示，并且过去式无人称和数的变化，即它不随主语变化。动词的过去式分为有规则变化和无规则变化两种情况。 无规则动词的过去式： 原形 过去式 原形 过去式 原形 过去式 am/is was are were bring brought buy bought come came cut cut bo/does did draw drew drink drank drive drove eat ate feed fed feel felt Fight fought find found fly flew forget forgot get got go went 习题训练： He doesn’t feel well and _________(not eat) any food this moring. --When ______you ________(write) this poem? --I _______(write)it last year. --What _______Bill _______(do) on Saturday afternoon? -- He _______(play)soccer and _________(read) an interesting book.
