初中英語句子成分解析

1、概念句子是由詞按照一定的語法結(jié)構(gòu)組成的。組成句子的各個(gè)部分叫做句子的成分。句子的成分包括：主語、謂語、表語、賓語（直接和間接賓語）、賓語補(bǔ)足語、定語和狀語。主語和謂語是句子的主體部分（在英語中，一般句子必須有主語和謂語），表語、賓語和賓語的補(bǔ)足語是謂語里的組成部分。其他成份如定語和狀語是句子的次要成分。句子成分分類1主語 主語是謂語講述的對象，表示所說的“是什么”或“是誰”。一般由名詞、代詞、不定代詞或相當(dāng)于名詞的單詞或短語來充當(dāng)，也有從句充當(dāng)?shù)默F(xiàn)象。大多數(shù)主語都在句首。如：講述“誰”We work in a big factory. 講述“什么”The classroom is very b

2、ig. 數(shù)詞作主語Three are enough. 三個(gè)人就夠了不定式作主語To operate on the blind is one of the ORBIS Doctors job.從句作主語What we need is food. 我們最需要的是食物.在“There be ”句型中，主語的位置在中間。如：There are some bottles of milk in the box. 在個(gè)別句型中，主語在整個(gè)句子后面，這時(shí)前面用it作形式主語。如： It is very interesting to play the game called “treat or trick”.

3、It took two workers about three months to build the house.2謂語謂語時(shí)用來說明主語“做什么”、“是什么”或“怎么樣”，謂語必須是動(dòng)詞，謂語和主語在“人稱”和“數(shù)”兩方面必須一致。如：He is very generous.She looks very smart and coolWe have finished the job.He can speak German.3表語 表語說明主語“是什么”或“怎么樣”，由名詞、形容詞、介詞、副詞、不定式及相當(dāng)于名詞的詞或短語來充當(dāng)，它的位置在系動(dòng)詞后面。 形容詞作表語You look young

4、er than before. 名詞作表語 My father is a teacher. 副詞作表語Everyone is here.介詞短語作表語They are at the theatre.不定式作表語My job is to teach them English.動(dòng)名詞作表語Her job is training the nurses.從句作表語That is why he didnt come to school yesterday.4賓語賓語是動(dòng)作、行為的對象，由名詞、代詞、不定式、或相當(dāng)于名詞的詞或短語或從句來充當(dāng)，它和謂語動(dòng)詞一起說明主語是什么，通常放在謂語動(dòng)詞后面。有時(shí)，會(huì)

5、有雙賓語。如：名詞作賓語He never forgives others for their mistakes.代詞做賓語He often helps me.不定式作賓語He likes to sleep in the open air.動(dòng)名詞作賓語The Americans enjoyed living in China.從句做賓語I believe that they can finish the work in time.直接賓語和間接賓語及物動(dòng)詞作謂語時(shí)，后面要跟賓語，賓語分直接賓語和間接賓語。直接賓語是及物動(dòng)詞的對象。但有些動(dòng)詞除了直接賓語外，還需要有一個(gè)間接賓語，間接賓語表語動(dòng)作是

6、對誰做的，所以只能用名詞或代詞來充當(dāng)。如：We brought them some food.主 謂 間賓 直賓間接賓語可以放在直接賓語后面，但必須加to 或 for。5賓語的補(bǔ)足語 在英語的句子中有些句子里只有賓語并不能表達(dá)完整的意思，還必須在賓語后面加上賓語的補(bǔ)足語才能表達(dá)完整的意思。我們把“賓語賓語補(bǔ)足語”合起來稱為復(fù)合賓語。復(fù)合賓語所表達(dá)的意思相當(dāng)于一個(gè)巨資的意思。名詞、動(dòng)詞、形容詞、副詞、介詞短語、不定式、現(xiàn)在分詞、過去分詞都可以作賓語補(bǔ)足語.如:名詞作賓補(bǔ) If you let me go, Ill make you king.形容詞作賓補(bǔ) Dont make your hands

9、fore Friday?“賓語+副詞”。副詞作賓補(bǔ)常表示賓語的狀態(tài)，與賓語有邏輯上的主表關(guān)系。常見的副詞有：down, up, here, there, home, in, out, anywhere等。如： Let him in/ out. Mr. Li drove us home.When got there, we found him out.“賓語+介詞短語”。介詞短語作賓補(bǔ)常表示其邏輯主語（即賓語）所處的狀態(tài)，兩者有主表的關(guān)系。如： We found everything in good order. We regard him as our good friend.He opene

10、d the door and found some of his friends in the rain.“賓語+不定式”。充當(dāng)賓補(bǔ)的不定式有三種： A 要求帶to的不定式The cool water of the lake invited us to swim.

11、es helps her mother (to) do housework.“賓語+現(xiàn)在分詞”?，F(xiàn)在分詞作賓補(bǔ)，此時(shí)在該句型中的賓語即為現(xiàn)在分詞邏輯上的主語，有著主謂關(guān)系。 I saw them playing on the playground.I heard Mary singing in the classroom.“賓語+過去分詞”。賓語和賓補(bǔ)之間是被動(dòng)關(guān)系，過去分詞表示被動(dòng)和完成。 I had my bike stolen. The teacher explained again and again to make himself understood. 形式賓語形容詞 We fou
