(3)以s、x、sh、ch結尾的加es

There be 句型
There be ...句型表示的是“某處有(存在) 某人或某物”。1. 肯定句結構：There be (is，are)+名詞+地點狀語e.g. 在我的鉛筆盒里有兩塊橡皮。 _____ ___ tw erasers in my pencil bx. 在房子前有一棵大樹。_____ __ a tall tree in frnt f the huse.2. 否定句結構：There isn’t / aren’t…e.g. 大橋街上沒有銀行。______ _____ a bank n Bridge Street.教室里沒有籃球。 ______ ______ any basketballs in the classrm.
There isn’t
There aren’t
3.一般疑問句結構：Is/ Are + 主語 +…? 肯定回答：Yes, there is/are. 否定回答：N, there isn’t/aren’t. e.g. 這附近有餐館嗎？ ___ ______ a restaurant near here? 教室里有學生嗎？___ _____ any students in the classrm? 4.there be句型一般現(xiàn)在時的特殊疑問句由“特殊疑問詞＋is/are＋there＋地點狀語”構成，有時地點狀語可省略。答語不能用Yes或N，需根據(jù)情況直接回答。e.g.—Hw many apples are there in the bag？包里有多少蘋果？ —Five.五個。
Is there
注意：1.There be句型中be動詞的形式要和其后面的主語在人稱和數(shù)上保持一致。即There be 句型中的主謂一致原則。e.g. 緊挨著郵局有一個投幣電話。 _____ __ a pay phne next t the pst ffice. 公園里很多樹。 _____ ____ many trees in the park. 2. 如果有兩個或兩個以上的名詞作主語，be動詞要和最靠近它的那個主語在數(shù)上保持一致，也就是我們常說的 “就近原則”。e.g. 在桌子上有一個桔子和幾根香蕉。 _____ __ an range and sme bananas n the table. 在桌子上有幾根香蕉和一個桔子。 _____ ___ sme bananas and an range n the table.
There are
3.there be與have/has的區(qū)別there be 和have都可譯為漢語里的“有”，但有區(qū)別：1) there be 結構表示的是“某地有某物/人”, 強調“存在關系”; have表示“某人/ 物所有”, 強調“所屬關系”。如: There is a bus in ur factry. (公共汽車不一定是屬于我們工廠所有的) Our factry has a bus. (公共汽車是屬于我們工廠所有的)2.當表示某物的構成和組成部分時, 用there be 和have均可。例如： Our schl has twenty classes. (= There are twenty classes in ur schl.)
1. There is a banana n the table. ?(改為一般疑問句并作否定回答) —_____ _______ a banana n the table? —____, _______ _______. 2. There is sme water in the cup.?? (改為否定句) ______ _______ any water in the cup. 3.
