    【篇一】
    There be句型知識點
    (1)There be句型主要用以表達“某處(某時)有某人(某物)?!逼浠窘Y(jié)構(gòu)為“There be+某物(某人)+某地(某時)”其中there是引導(dǎo)詞,沒有詞義;主語是be后面的名詞, be是謂語動詞,在一般現(xiàn)在時中be只用is和are兩種形式。下面這首歌訣可幫你巧記there be句型結(jié)構(gòu):
    There be放句首,主語跟在后。地、時放句末,強調(diào)置前頭。如:There is a book on the desk.有時為了強調(diào)地點,也可把介詞短語放在句首。如:
    On
    the desk there is a book.
    (2)There be句型中的be動詞如何確定呢?請先看看下面這首歌訣:Be動詞,有三個,am,is還有are。“There be”真特別,不留am只留倆,那就是is還有are。要用is還是are,須看其后的名詞是單數(shù)還是復(fù)數(shù)。若是單數(shù)或不可數(shù)名詞用is,否則就用 are。如:①There is a tree behind the house.②There is some water(水)in the bottle(瓶子).
    ③There
    are some pears in the box.
    (3)注意:如果“be”后的主語是由and連接的兩個或兩個以上的名詞,那么be的形式要遵循“遠親不如近鄰”的原則。也就是說,“be”的形式是 由與它最近的那個名詞來確定的。若那個名詞是單數(shù)或不可數(shù)名詞要用is,是復(fù)數(shù)就用are。如:①There is a book and some pens on the floor.②There are some pens and a book on the floor.
    【練習(xí)題】
    用is或are填空
    1.There________many monkeys in the mountain. 3. There _________some water in the glass. 5. _________there any maps on the wall? 7.

    【篇二】
    this,that和it用法
    (1)this和that是指示代詞,it是人稱代詞。
    (2)距離說話人近的人或物用this, 距離說話人遠的人或物用that。如: This is a flower. 這是一朵花。(近處)
    That is a tree. 那是一棵樹。(遠處)
    (3)放在一起的兩樣?xùn)|西,先說this, 后說that。如:
    This is a pen. That is a pencil. 這是一支鋼筆。那是一支鉛筆。
    (4)向別人介紹某人時說This is…, 不說That is…。如:
    This is Helen. Helen, this is Tom. 這是海倫,海倫,這是湯姆。
    (5)This is 不能縮寫, 而That is可以縮寫。如:
    This is a bike. That’s a car. 這是一輛自行車。那是一輛轎車。
    (6)打電話時,介紹自己用this, 詢問對方用that。如:
    -Hello! Is that Miss Green? 喂,是格林小姐嗎?
    -Yes, this is. Who’s that? 是的,我是,你是誰?
    注意:雖然漢語中使用“我”和“你”,但英語中打電話時絕不可以說:I am…, Are you…?/Who are you?
    (7)在回答this或that作主語的疑問句時, 要用it代替this或that。如:
    ①-Is this a notebook? 這是筆記本嗎?
    -Yes, it is. 是的,它是。
    ②-What’s that? 那是什么?
    -It’s a kite. 是只風(fēng)箏。
