(一)情態(tài)動詞cancan 在英語中有一個特殊的名字,叫做情態(tài)動詞,表示“能夠”, “會”, “能力”后面要跟著表示動作的動詞。沒有時態(tài)和人稱的變化。表示不能做什么的時候,后面加上 not為can not,或者縮寫為can’t。問別人“能…嗎?”要把can 放在句子前面,首字母要大寫,句尾別忘加上問號。
(二)人稱代詞所屬格
注意:主格作主語,其中she指帶代國家,it可指代天氣時間等。
賓格作賓語,介詞賓語,表語。動詞后面用人稱賓格
形容詞性物主代詞作定語。
名詞性物主代詞作主語,賓語,介詞賓語,表語書信yours…
表示 ---- 的,這樣的詞我們也學(xué)習(xí)很多了,你能想出來嗎?
記住這個小口訣就很容易了:我的 my ,你的your,他的 his、她的her. //它的是its; 我們的 our; 你們的是 your他們(它們,她們)的是their//這些人稱代詞形式稱為人稱代詞所屬格,也叫形容詞性物主代詞。通常用在名詞前面表示所屬關(guān)系。另外,表示某人的還可以用名詞或人名+ ’s 來表示。如:
my kite;your book;his pen;her coat;its tail;our class;
their teachers;my brother’s;book;the cat’s ears;Mary’s mother

1 、過去完成時是一個相對時態(tài),表示過去的過去,只有在兩個過去發(fā)生的動作相比較時才可顯示出來。As soon as we got to the station, the train had left.
注:主從句表達的動作緊接時,即兩動作發(fā)生的時間沒有明顯時間上的懸殊或空檔時,主從句都可用一般過去時。
e.g. Where did your brother study before he joined the army?
2 、過去完成時可表示截止過去某一時間動作的總或動作的結(jié)束。
By the end of last month. We had reviewed four books
By eight o`clock, he had finished his homework.
與這個時態(tài)連用的時間狀語常有:
by 1985, by eight o`clock, by then, by the end of last month, by the time when, when, as soon as, before 等連詞引導(dǎo)的時間狀語從句,表示主句動作結(jié)束的時間。

現(xiàn)在進行時主要用于:1 、表示現(xiàn)在或現(xiàn)階段正在進行的動作。
e.g. Listen, someone is crying.
What are you doing these days?
2 、代替一般現(xiàn)在時,表示經(jīng)常性動作或狀態(tài),而含有某種感情 色彩。
e.g. How are you feeling today?
你今天感覺怎樣?(顯得親切)
He is doing well in his lessons.

now, these days, recently, this week 等。
5.小學(xué)英語語法知識點
一般將來時主要用于:表示將要發(fā)生的動作或情況
e.g. Tom will have a bike of his own.
與這個時態(tài)連用的時間狀語常用:
tonight, tomorrow, the day after tomorrow, next week, in three hours, two days later 等。
一般將來時態(tài)與其它結(jié)構(gòu)表將來情況的區(qū)別:
一般將來時態(tài) :主要從時間的角度表將要發(fā)生的動作或情況。
be going to 結(jié)構(gòu) :①表(主觀上)打算或準(zhǔn)備做某事時。 ②表有發(fā)生某事的預(yù)兆時。
e.g. They are going to have a competition with us in studies. It is going to rain.
據(jù)以上區(qū)別,故下面一句是錯的:
I am going to be eighteen years old next year.
應(yīng)改為: I shall be eighteen years old next year.
be about to do sth 結(jié)構(gòu) :意為“剛要做某事”、“馬上要做某事”強調(diào)時間之緊迫性。
e.g. We are about to discuss this problem.
