    1.主謂賓結構。the farm 主語，covered 謂語，thousands of acres賓語
    2.祈使句結構。省略主語。
    3.主系表結構。后面有補語to be visited。
    4.倒裝句結構。only提前，疑問句語序
    5.主系表結構，被動語態(tài)
    6.主謂賓結構，后面有狀語by bus
    7.there be 句型，某處有某物，主系表結構，后面有不定式做補語。
    8.主謂賓。狀語by chance
    9.主謂結構，后面是狀語
    10.主謂，動詞不定式做補語
    11.主謂賓結構
    12.主系表。considering her age狀語
    13.從句。省略了主語
    14.主系表。動詞不定式做主語和表語
    15.主系表，
    16.主謂結構
    17.現(xiàn)在進行時態(tài)，主系表結構，不定式做補語
    18.主謂賓，否定式，
    19.主謂賓。we 主語，think 謂語，it is necessary to work hard賓語，賓語是一個句子，在賓語中又是一個主系表結構的句子，it是形式主語，動詞不定式是真正的主語，這是為了避免頭重腳輕。
    20.主系表?，F(xiàn)在分詞做主語。
    
    備注：賓語為動詞，“系“指”be"動詞。如果是從句，就要先找出這個句子的主干部分，然后再劃分其他的成分，如第19.劃分句子結構其實很簡單，主謂賓定狀補，記住這6個字，多練習。句子劃分都大同小異，所以有的句子沒有像例1那樣寫出句子成分。

  英語語法問題：什么樣的單詞后面要加ing，be怎么用，the與an的區(qū)別，復數(shù)形式單詞后面為什有加s，也有加es
  • 郎老師
    一、加ing
    ①動詞如果作為伴隨狀語，賓語，主語的時候，要加ing
    例如：swimming is my hobby.【游泳是我的愛好】游泳作為主語就要加ing
    my job is teaching.【我的工作是教書】教書作為賓語就要加ing
    there is a girl wearing a white t-shirt.【有一個穿白t恤的女孩】穿作為伴隨狀語要加ing
    ②形容詞修飾物時要加ing [通常翻譯為：令人……]
    the news is exciting to me【這個新聞令我很興奮】
    
    二、be的用法
    be是動詞，一般現(xiàn)在時為：amisare 一般過去時為：waswere
    可用做謂語，還屬于系動詞，常見的有系表結構（系動詞+表語）等
    例如：i am a girl【我是一個女孩兒】
    the flowers are very beautiful【這些花兒非常漂亮】
    
    三、the和an/a的區(qū)別
    the是定冠詞，一般用于特指
    例如：the man is my father【這個男人是我的爸爸】
    a/an是不定冠詞，an用于元音發(fā)音單詞前[如applehour]
    例如：i am working for an hour.【我已經持續(xù)工作了一個小時】
    i need an apple to eat【我需要吃一個蘋果】
    
    四、-s和-es
    加es為特殊，一般在以sxshch結尾的單詞后加。例如：boxes【盒子】，fishes【魚，強調種類的復數(shù)，數(shù)量的復數(shù)則為原型】，matches【比賽、火柴】
    特殊：以o結尾的個別單詞：tomatoes【西紅柿】potatoes【土豆】heroes【英雄】
    
    另外補充吧，有些名詞單復數(shù)同型，例如：deer【鹿】fish【魚，強調數(shù)量】chinese【中國人】japanese【日本人】sheep【綿羊】
