i was there a moment ago. 刚才我在那儿。

二、构成。三、动词过去式变法。

动词过去式的构成分规则变化和不规则变化两种形式。

规则变化遵循以下原则:

1. 一般在动词后加-ed。如:

play—played, offer—offered, weigh—weighed, destroy—destroyed, sign—signed。

2. 在以字母e结尾的动词后,只加-d。如:like—liked, provide—provided, hate—hated, date—dated。

3. 在以“辅音字母+y”结尾的动词后,则改y为i,再加-ed。如:supply—supplied, fly—flied, study—studied。

4. 在以重读闭音节结尾且末尾只有一个辅音字母的动词后,双写最后一个辅音字母,再加-ed。如:

plan—planned, refer—referred, regret—regretted, ban—banned。

不规则变化需要特殊记忆:

am/is—was, are—were, begin—began, bring—brought, build—built, buy—bought, can—could, go—went, give—g**e, come—came, do—did, feel—felt, h**e/has—had, keep—kept

四、一般过去时的应用。

1. 表示过去发生的动作或存在的状态。

he bought the computer five years ago. 这电脑是他五年前买的。

it was then a small fishing village. 那时它只是一个小渔村。

2. 表示过去经常性或习惯性的动作。

we often played together when we were children. 我们小时候常在一起玩。

we often went out for a walk after supper. 我们过去常在晚饭后散步。

三、不定代词

由some, any, no, every与thing, one, body 构成的不定代词称为复合不定代词。

someone / somebody 某人 something 某事;某物

anyone / anybody 任何人 anything 任何事物

no one / nobody 无人;没有人 everyone / everybody 每人。

everything 每一件事物;一切 nothing 没有什么。

1).复合不定代词作主语时,都做单数看待,谓语动词用第三称单数。

no one knows the answer. 没有人知道这个答案。
