1、主系表結(jié)構(gòu) There be句型,1,一、主系表結(jié)構(gòu),主謂賓=主語+實(shí)義動詞+賓語，be是系動詞，不能用于主謂賓中。 主系表=主語+系動詞(最常見的是be，還有“五感”feel、look、sound、smell、taste和其它動詞如become、grow等）+表語（名詞、代詞、形容詞、時間地點(diǎn)副詞、介詞短語、表語從句等）。,2,,,如I am a boy.這句話中沒有賓語，屬于主系表，I是主語，系動詞am是謂語動詞，a boy是表語，系動詞和表語合起來作謂語。由此可見在主系表中，謂語謂語動詞；而在主謂賓中，謂語=謂語動詞，如I love my parents. 總之，系動詞和賓語是不共戴天的

2、仇人，誓不兩立。系動詞后面接的是表語，而賓語前面接的是謂語。,3,所謂主系表結(jié)構(gòu)就是英語句子中的主要成分是主語、系動詞和表語。主要用以說明主語的特征，狀態(tài)，身份等。,定義,主系表（S+V+P）： 1. 主語（ Subject ） 2. 系動詞（ Link verb ） 3. 表語（ Predicative）,4,所謂主系表結(jié)構(gòu)就是英語句子中的主要成分是主語、系動詞和表語。主要用以說明主語的特征，狀態(tài)，身份等。 1. 主語（ Subject ）：主語是一句話的中心，表示所說的是誰或是什么，其位置一般放在句首。英語中主語一般不省略。主語主要由名詞、動名詞、代詞或起名詞作用的短語或從句來充當(dāng)。 例

3、如： Li Lei is a Chinese boy. （ Li Lei 是名詞，作主語。） He is from England. （ He 是代詞，作主語。） Feeding the birds is my hobby. （“ Feeding the birds ”是動名詞短語，作主語。） What she said is right. （“ What she said ”是從句，作主語。,5,2. 系動詞（ Link verb ）：系動詞本身有一定的詞義，但不能獨(dú)立作謂語，必須和句子中的表語一起構(gòu)成謂語。簡單地說，將主語和表語聯(lián)系在一起，并構(gòu)成一個完整句子的動詞就叫做系動詞。目前學(xué)到

4、的系動詞有 be ， feel ， look ， sound ， taste ， smell 等。 例如：This flower is beautiful. I felt very tired. You look worried. It tastes delicious.,6,常見的系動詞,（1）表示特征和存在狀態(tài)的 be, feel, look, smell, taste, sound. （2）表示狀態(tài)延續(xù)的 keep （3）表示狀態(tài)變化的 become, get, turn, go, come,7,3. 表語（ Predicative ）：表語是用來說明主語的身份、特征或狀態(tài)的

5、。它又叫作主語補(bǔ)足語。表語位于系動詞之后，主要由名詞、代詞、形容詞、數(shù)詞、副詞、介詞短語、分詞（短語）或動名詞（短語）等來充當(dāng)。例如： I am fine . （ fine 是形容詞，作表語） He is a boy . （ boy 是名詞，作表語） Five plus two is seven . （ seven 是數(shù)詞，作表語） We are here . （ here 是副詞，作表語） He is not at home . （“ at home ”是介詞短語，作表語） My hobby is reading . （ reading 是動名詞，作表語）,8,,,二、There be 句型
