小學英語知識歸納
句型專項歸類
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.
☆注意 小結:否定句主要是在肯定句的基礎上加上了否定詞 ―not‖。有動詞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。沒有動詞be的句子則要先在主要動詞的前面加上一個助動詞(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 )。這三個助動詞要根據人稱和時態來選擇,其中―does‖只用于一般現在時主語是第三人稱單數的情況,而―did‖只用于一般過去時,不論主語是什么人稱和數,都用―did‖ 。
3、一般疑問句:是指詢問事實的句子,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.
4、特殊疑問句:以特殊疑問詞(what , where , who , which , when , whose , why , how等)開頭引導的句子。此類句子應該問什么就答什么,不能用
―yes 、no‖來回答。如:
What is this? It’s a computer.
What does he do? He’s a doctor.
小學英語知識總結
動詞過去式詳解 動詞的過去式的構成規則有:
A、規則動詞
① 一般直接在動詞的后面加ed:如 worked , learned , cleaned ,
visited
② 以e結尾的'動詞直接加d:如 lived , danced , used
③ 以輔音字母加y結尾的動詞要改y為i再加ed(此類動詞較少)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)
④ 雙寫最后一個字母(此類動詞較少)如 stopped
B、不規則動詞(此類詞并無規則,須熟記)小學階段要記住以下動詞的原形和過去式:
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
小學英語知識要點
現在完成時主要用于:
1 、表示到現在為止這一時期中發生的動作或情況,即多次動作的總和。
e.g. We have learnt four English songs this month.
How many times have you read the novel?
For many days we haven`t seen each other.
2 、表示對現在有影響的某一已發生的動作。
e.g. The delegation has left 代表團已經走了(說明現在不在這里) Look, what you have done. 看你干的事。
與這一時態連用的時間狀語有:
already, yet, just, ever, never, by now, so far, recently, by the end of this month, since, for 短語,連詞 since 引導的時間狀語從句。 一般過去時與現在完成時的區別:
一般過去時:重在說明動作在過去發生時的具體情況(時間、地點、方式、對象、細節等)。
現在完成時:只提起已發生的動作(事實)及其影響,不說明動作發生時的具體情況。
cf. Have you had your lunch?
What did you have for lunch?
I have ever been to the Great Wall,_and_I went there last summer with my father.
注:現在完成時表達的動作常具有反復性,故下面一句是錯的:
Have you seen the six thirty`s news program?
應改為:
Did you see the six thirty`s news program?
