语法预习清单
第一部分 核心语法详细讲解
一、一般过去时
【概念】
一般过去时表示过去某个时间发生的动作或存在的状态,也可以表示过去经常或反复发生的动作。
【标志词】
yesterday(昨天), last week(上周), last year(去年), two days ago(两天前), just now(刚才), in 2001(在2001年)等。
【构成与变化规则】
1. Be动词的过去式:
I / He / She / It + was(否定:wasn't)
We / They / You + were(否定:weren't)
例句:Mike was in Shenzhen yesterday. They were at school last week.
2. 实义动词的过去式:
规则变化:
一般情况直接加 -ed:play → played, join → joined, call → called, check → checked
以字母e结尾,直接加 -d:move → moved, like → liked
以辅音字母+y结尾,变y为i加 -ed:study → studied, cry → cried
重读闭音节(辅音+元音+辅音),双写尾字母加 -ed:stop → stopped, plan → planned
不规则变化(必须死记硬背):
go → went, do → did, have → had, see → saw
make → made, break → broke, wear → wore, take → took
get → got, throw → threw, meet → met, is/am → was, are → were
3. 否定句与一般疑问句:
借助助动词 did(此时动词一律还原为原形)。
否定:主语 + didn't + 动词原形。 例:He didn't go to school yesterday.
疑问:Did + 主语 + 动词原形? 例:Did you see the film? — Yes, I did. / No, I didn't.
【易错点提醒】
看到过去的时间状语(如yesterday),动词一定要用过去式,不要忘记变形!
二、形容词与副词的比较级、最高级
【概念】
比较级:用于两者(人或物)之间的比较,表示“A比B更……”。常与 than 连用。
最高级:用于三者或三者以上之间的比较,表示“在……中最……”。常与 the 以及 of/in 构成的短语连用。
【构成规则】
1. 单音节词:
一般加 -er / -est:fast → faster → fastest; slow → slower → slowest
以e结尾加 -r / -st:nice → nicer → nicest; late → later → latest
重读闭音节双写尾字母加 -er / -est:big → bigger → biggest; hot → hotter → hottest
2. 双音节词:
辅音字母+y结尾,变y为i加 -er / -est:heavy → heavier → heaviest; early → earlier → earliest
部分双音节词和多音节词,在词前加 more / most:slowly → more slowly → most slowly; difficult → more difficult → most difficult
3. 不规则变化(必背):
good / well → better → best
bad / badly → worse → worst
many / much → more → most
little → less → least
【句型用法】
比较级句型:A + is/动词 + 比较级 + than + B.
A car is faster than a horse.
Eddie runs more slowly than Peter.
最高级句型:A + is/动词 + the + 最高级 + of/in + 范围.
A plane is the fastest of all.
Mark runs the most slowly of the three.
【易错点提醒】
形容词最高级前一般要加定冠词 the;但副词最高级前的the可以省略。
三、There be句型与不定代词
【There be 句型】
表示“某地存在某物”,遵循就近原则(只看离There最近的那个名词)。
一般现在时:There is + 单数可数名词/不可数名词;There are + 复数可数名词。
一般过去时:There was + 单数/不可数;There were + 复数。
例句:There is a park near my home. / There are many interesting places in Beijing. / There was a small town in 1979.
【不定代词 nobody, no one, nothing】
nobody / no one 表示“没有人”。作主语时,谓语动词必须用单数。
nothing 表示“没有东西;没有什么”。作主语时,谓语动词也必须用单数。
例句:Nobody is in the museum. / There is nothing in the fridge. / No one could see everything.
四、顺序词与情态动词
【顺序词】
描述做事的步骤时,使用 First(首先), Next(接下来), Then(然后), Finally(最后),可以使文章条理清晰。
例句:First, put on your swimsuit. Next, do warm-up exercises. Then, put on your goggles. Finally, get into the water.
【情态动词 can, must, should】
表示能力(能/会)、义务(必须)、建议(应该)。
核心规则:情态动词后直接跟动词原形,且无人称和数的变化(不加s,不变过去式)。
should (应该) / shouldn't (不应该);must (必须) / mustn't (禁止);can (可以/能够) / can't (不能)。
例句:We should warm up before doing exercise. We shouldn't play with fire.
五、四大基础时态综合复习
1. 一般现在时(表示经常性、习惯性的动作或客观真理)
标志词:often, usually, always, every day等。
构成:主语 + 动词原形/动词三单(当主语是第三人称单数时,动词加-s或-es)。
例句:He goes to school by bus every day. Peter runs slowly.
2. 现在进行时(表示现在正在进行的动作)
标志词:now, look, listen等。
构成:主语 + am/is/are + 动词-ing。
例句:Look! The children are playing football. I am reading a book now.
3. 一般将来时(表示将来要发生的动作或存在的状态)
标志词:tomorrow, next week, this weekend等。
构成:主语 + will + 动词原形 / 主语 + am/is/are going to + 动词原形。
例句:We will visit the Great Wall next week. She is going to buy some food.
4. 一般过去时(前面已详述,此处略)。
