学习知识的最终目的是将知识灵活运用到现实生活、学习中,学中用、用中学是学习知识的一个重要原则,英语词汇学习亦如此。那英语的基础知识都有哪些呢?下面我给你分享英语的基本知识点,欢迎阅读。
英语的基本知识点【1】
名词的变化规律
1. 一般情况下加s (如cats, dogs, friends, books, papers等)
2. 以s, x, ch, sh 结尾的加es (如buses, boxes, matches, flashes等)
3. 以辅音字母+y 结尾的名词,把y 改为i 再加es (如ladies, stories, candies等) 但要注意的是以元音字母加y结尾的名词的复数形式只加s,如:boy→boys, day→days。
4. 部分以o 结尾的名词,有生命的加es, 没生命的加s (如potatoes, tomatoes, photos, pianos等),以oo 结尾一般情况下加s (如zoo, kangaroo等)
5. 以f 或fe 结尾的名词,多把f 或fe 改为v再加es (如knives, shelves, leaves等)
(7)少数名词有不规则的复数形式,例如:man→men,woman→women,tooth→teeth,foot→feet,child→children,mouse→mice。
【注意】与man和woman构成的合成词,其复数形式也是-men和-women。例如:an Englishman,two Englishmen。但German不是合成词,故复数形式为 Germans;man, woman等作定语时,它的单复数以其所修饰的名词的单复数而定,如:men workers, women teachers。
有个别名词单复数一样,例如:Chinese,Japanese,sheep,deer,fish等。但当fish表示不同种类的鱼时,可以加复数词尾。
复数词尾s(或es)的读音方法
1、在[p][t][k][f]等清辅音后读[s] ,如cups, hats, cakes。
2、在[s][z][t][ ][f]等音后读[iz],如glasses, pages, oranges, buses, watches,faces。
3、在[b][d][ g][v]等浊辅音后读[z],如beds, dogs, cities, knives。
英语的基本知识点【2】
动词各种时态的变化
一、动词三单形式的变化规律
1. 直接在动词后加s ,如want—wants, work—works, know—knows, help—helps,get—gets。
2. 以s, x, ch, sh 结尾的动词在后面加es ,如watch—watches,catch—catches。
3. 以辅音字母加o 结尾加es ,如go—goes,do—does。
4. 以辅音字母加y 结尾,把y 改为i 再加es ,如study—studies,carry—carries,fly—flies,worry—worries
5. 以元音字母加y 结尾,直接加s ,如play—plays.
6. 不规则变化
二、动词ing 的变化规律:
1.英语动词加-ing,通常是在原形词尾直接加-ing构成:cough—coughing,climb—climbing,stand—standing,fight—fighting
2.以-e结尾的动词
(1)如果动词原形以一辅音加一不发音的-e结尾,一般应去掉e再加ing:
write—writing,hope—hoping,care—caring,stare—staring,plane—plan-ing,have—having,save—saving, produce—producing, breathe—breathing (2)以-ie结尾的动词应先将e去掉,将i变成y然后再加-ing: die—dying,tie—tying,vie—vying,lie—lying
(3)以-ee,-oe,-ye结尾的动词加-ing时应保留词尾e:
see—seeing,flee—fleeing,free—freeing,agree—agreeing,hoe—hoeing, dye—dyeing,eye—eyeing
(4)以-ue结尾的动词大多应先去e再加-ing:
sue—suing,imbue—imbuing,construe—construing,pursue—pursuing,rue—ruing 有时,词尾e可去掉也可保留: glue—gluing或 glueing,cue—cuing或 cueing, blue—blueing或 bluing, true—truing或trueing,clue—clueing或cluing
3.以一元音加一辅音结尾的动词
(1)如果动词最后一音节为重读闭音节,最后一个字母需要重复:
run—running, stop—stopping, hop—hopping, plan—planning,star—starring, control—controlling但辅音x是个例外,无需重复(x其实起着两个辅音的作用): tax—taxing,relax—relaxing
(2)如果动词最后一个音节为次重读音节,最后一个字母有时也重复: kidnap—kadnapping或kidnaping,program—programming或programing
(3)如果动词最后一个音节为非重读音节,最后一个字母大多无需重复:
open—opening,offer—offering,audit—auditing但在有些动词中,重复或不重复均可: worship—worshiping或 worshipping,focus—focusing或 focussing,cancel—canceling或cancelling,travel—traveling或travelling
以非重读的-el结尾的动词加-ing时,英国英语习惯于重复词尾l,而美国英语则习惯于不重复1。
4.若动词以一元音加一半元音(y或w)结尾,可直接加-ing:
pay—paying, throw—throwing,follow—following, draw—drawing, em-ploy—employing
5.以-ic结尾的动词应先在字母c后加一字母k再加-ing:
frolic—frolicking,panic—panicking,mimic—mimicking,picnic—picnicking,traffic—trafficking
三、动词过去式的变化规律:
1.一般在动词末尾加-ed,如:pull-pulled, cook-cooked
2.结尾是e加d,如:taste-tasted
3.末尾只有一个元音字母和一个辅音字母的重读闭音节,应双写末尾的辅音字母,再加-ed,如:stop-stopped
4.以“辅音字母+y”结尾的,变y为i, 再加-ed,如:study-studied
5.不规则动词过去式:
am,is-was are-were do-did see-saw say-said
give-gave get-got go-went come-came have-had
eat-ate take-took run-ran sing-sang put-put
make-made read-read write-wrote draw-drew
drink-drank fly-flew ride-rode speak-spoke
sweep-swept swim-swam sit-sat
形容词比较级
1、一般在词尾加er 如long变为longer
2、以不发音的字母e结尾的加r 如late变为leter
3、以重读闭音节结尾的词,而词尾只有一个辅音字母时,先双写这一辅音字母,再加er 如hot变为hotter
4、以辅音字母加y结尾的双音节词先变y为i再加er 如happy变为happier 多音节词在词前加more 如quickly变为more quickly
另外还有一些不规则变化 如good变为better many变为more 这类问题要注意积累 一般在词尾加er 如long变为longer 。

(三)There be句型
There be 句型与have, has的区别:
1、There be 句型表示:在某地有某物(或人)
2、在there be 句型中,主语是单数,be 动词用is 主语是复数,be 动词用are 如有几件物品,be 动词根据最*近be 动词的那个名词决定。
3、there be 句型的否定句在be 动词后加not , 一般疑问句把be 动词调到句首。

6、and 和or 在there be句型中的运用:and 用于肯定句, or 用于否定句或疑问句。
7、针对数量提问的特殊疑问句的基本结构是:
How many + 名词复数 + are there + 介词短语? How much + 不可数名词 + is there + 介词短语 ?
8、针对主语提问的特殊疑问句的基本结构是: What‘s + 介词短语?
