在我們的學(xué)習(xí)時(shí)代，大家都背過不少知識(shí)點(diǎn)，肯定對知識(shí)點(diǎn)非常熟悉吧！知識(shí)點(diǎn)在教育實(shí)踐中，是指對某一個(gè)知識(shí)的泛稱。相信很多人都在為知識(shí)點(diǎn)發(fā)愁，以下是小編收集整理的小升初英語必背知識(shí)點(diǎn)，歡迎大家借鑒與參考，希望對大家有所幫助。
小升初英語必背知識(shí)點(diǎn)1
一、學(xué)生易錯(cuò)詞匯：
1.a, an的選擇:元音字母開頭的單詞用an，輔音字母開頭的單詞用a.
2. am , is , are的選擇:單數(shù)用is ,復(fù)數(shù)用are. I用am , you用are.
3. have , has的選擇:表示某人有某物。單數(shù)用has ,復(fù)數(shù)用have. I , you用have .
4. there is, there are的選擇:表示某地有某物，某人。單數(shù)用there is ,復(fù)數(shù)用there are.
5. some, any的選擇:肯定句用some,疑問句和否定句用any.
6.疑問詞的選擇:what (什么) who (誰) where (哪里) whose (誰的) why(為什么)when(什么時(shí)候)
which(哪一個(gè))how old (多大) how many (多少)how much(多少錢)
二、形容詞比較級(jí)詳解：
當(dāng)我們需要對事物作出比較時(shí)，需要用到比較級(jí)。比較級(jí)的句子結(jié)構(gòu)通常是：
什么+動(dòng)詞be (am , is , are ) +形容詞比較級(jí)+ than(比)+什么,如：
I’m taller and heavier than you. (我比你更高和更重。)
An elephant is bigger than a tiger. (一只大象比一只老虎更大。)
形容詞的比較級(jí)是在形容詞的基礎(chǔ)上變化而來的，它的變化規(guī)則是：
�、僖话愕闹苯釉谠~尾加er，如tall - taller , strong - stronger ,
�、谝詄結(jié)尾的，直接加r，如fine – finer ,
�、垡暂o音字母加y結(jié)尾的，先改y為i再加er，如funny - funnier
�、茈p寫最后的字母再加er，如big – bigger, thin – thinner ,hot – hotter
☆注意比較的兩者應(yīng)該是互相對應(yīng)的可比較的東西。
典型錯(cuò)誤：My hair is longer than you.(我的頭發(fā)比你更長。)
比較的兩者是我的頭發(fā)、你(整個(gè)人)，那么比較的對象就沒有可比性。
應(yīng)該改為：My hair is longer than yours.或My hair is longer than your hair.

三、動(dòng)詞過去式詳解
動(dòng)詞的過去式的構(gòu)成規(guī)則有：
A規(guī)則動(dòng)詞
�、僖话阒苯釉趧�(dòng)詞的后面加ed：如worked , learned , cleaned , visited
�、谝詄結(jié)尾的動(dòng)詞直接加d：如lived , danced , used
�、垡暂o音字母加y結(jié)尾的動(dòng)詞要改y為i再加ed(此類動(dòng)詞較少)如study – studied carry – carried worry – worried (注意play、stay不是輔音字母加y,所以不屬于此類)
�、茈p寫最后一個(gè)字母(此類動(dòng)詞較少)如stopped
B不規(guī)則動(dòng)詞
(此類詞并無規(guī)則，須熟記)小學(xué)階段要記住以下動(dòng)詞的原形和過去式：
sing – sang , eat – ate , see – saw , have – had , do – did , go – went , take – took , buy – bought , get – got , read – read ,fly – flew , am/is – was , are – were , say – said , leave – left , swim – swam , tell – told , draw – drew , come – came , lose – lost , find – found , drink – drank , hurt – hurt , feel – felt
四、動(dòng)詞現(xiàn)在分詞詳解
動(dòng)詞的ing形式的構(gòu)成規(guī)則：
①一般的直接在后面加上ing ,如doing , going , working , singing , eating
�、谝詄結(jié)尾的動(dòng)詞，要先去e再加ing，如having , writing
�、垭p寫最后一個(gè)字母的(此類動(dòng)詞極少)有：running , swimming , sitting , getting
五、人稱和數(shù)：
人稱代詞物主代詞
主格賓格
第一
人稱單數(shù)I(我) me my(我的)
復(fù)數(shù)we(我們) us our(我們的)
第二
人稱單數(shù)you(你) you your(你的)
復(fù)數(shù)you(你們) you your(你們的)
第三
人稱單數(shù)he(他) him his(他的)
she(她) her her(她的)
it(它) it its(它的)
復(fù)數(shù)they(他們/她們/它們) them their(他們的/她們的./它們的)
六、句型專項(xiàng)歸類：
1、肯定句：是指用肯定的語氣來陳述的句子，如：
I’m a student. She is a doctor. He works in a hospital.
There are four fans in our classroom. He will eat lunch at 12:00. I watched TV yesterday evening.
2、否定句：含有否定詞或表示否定意義詞的句子，如：I’m not a student. She is not (isn’t) a doctor.
He does not (doesn’t) work in a hospital. There are not (aren’t) four fans in our classroom.
He will not (won’t) eat lunch at 12:00. I did not (didn’t) watch TV yesterday evening.
☆小結(jié)：否定句主要是在肯定句的基礎(chǔ)上加上了否定詞“not”。有動(dòng)詞be的句子則“not”加在be后面，可縮寫成“isn’t，aren’t”，但am not一般都分開寫。沒有動(dòng)詞be的句子則要先在主要?jiǎng)釉~的前面加上一個(gè)助動(dòng)詞(do，does，did)，然后在它后面加上“not”，你也可以把它們縮寫在一起如“don’t , doesn’t , didn’t )。這三個(gè)助動(dòng)詞要根據(jù)人稱和時(shí)態(tài)來選擇，其中“does”只用于一般現(xiàn)在時(shí)主語是第三人稱單數(shù)的情況，而“did”只用于一般過去時(shí)，不論主語是什么人稱和數(shù)，都用“did” 。
3、一般疑問句：是指詢問事實(shí)的句子，此類句子必須用“yes”，或“no”來回答。
如：Are you a student? Yes, I am / No, I’m not.
Is she a doctor? Yes, she is. / No, she isn’t.
Does he work in a hospital? Yes, he does. / No, he doesn’t.
Are there four fans in our classroom? Yes, there are. / No, there aren’t.
Are you going to buy a comic book tonight? Yes, I am. / No, I am not. (Yes, we are. / No, we aren’t.)
Will he eat lunch at 12:00? Yes, I will. / No, I will not(won’t).
Are they swimming? Yes, they are. / No, they aren’t.
Did you watch TV yesterday evening? Yes, I did. / No, I didn’t.
☆小結(jié)：一般疑問句是在肯定句的基礎(chǔ)上
①把動(dòng)詞be調(diào)到首位，其他照寫，末尾標(biāo)點(diǎn)符號(hào)變成問號(hào)即可。
②沒有動(dòng)詞be的句子則要在句首加上一個(gè)助動(dòng)詞(do，does，did)再把緊跟在后面的動(dòng)詞變回原形，末尾標(biāo)點(diǎn)符號(hào)變成問號(hào)即可。
這三個(gè)助動(dòng)詞也要根據(jù)人稱和時(shí)態(tài)來選擇，其中“does”只用于一般現(xiàn)在時(shí)主語是第三人稱單數(shù)的情況，而“did”只用于一般過去時(shí)，不論主語是什么人稱和數(shù)，都用“did” 。一般疑問句有個(gè)重要的原則就是問和答要一致，即問句里的第一個(gè)單詞(助動(dòng)詞)和簡略答句里的這個(gè)詞是一致的。
