      2020中考英語精華知識點匯總
      英語語法重點與難點
      1、 as…as…結構:
      You’re a boy as good as Tom.=You’re as good a boy as Tom.
      你和湯姆是一樣好的孩子。
      2、 (1)too…to與 so…that sb. can’t…的句型轉換:前者為簡單句,主語只有一個,而后者為復合句,主語有兩個,試比較:
      The man was too angry to be able to speak.
      The man was so angry that he wasn’t able to speak.
      (2) too…to…與 not enough to句型的轉換:
      He is too young to get married.=He is not old enough to get married.
      The book is too difficult for me to read.=
      The book is not easy enough for me to read.
      3、 形容詞原級表示比較級含義:
      約翰不象邁克那么苯。
      John is not so stupid as Mike.
      John is less stupid than Mike.
      John is cleverer than Mike.
      4、 用比較級表示最高級:約翰是班里最高的男生。
      John is taller than any other boy in the class.
      John is the tallest boy in the class.
      5、 the more….. the more….表示“越……越……”:
      The more books you read, the wider your knowledge is.
      The more food you eat, the fatter you are.
      6、 more and more….表示“越來……越……”:
      More and more students realized the importance of a foreign language.
      Our country is getting stronger and stronger.
      情態動詞
      1.考查情態動詞表示“推測”的用法
      [考點快憶] 表示肯定推測的情態動詞有:must“一定;準是”,may“也許;可能”,might“或許”;表示否定推測的情態動詞有:can't“不可能”, couldn't“不會”,may not“也許不”,might not“或許不”;can表示推測時不用于肯定句,may表示推測時不用于疑問句。
      2.考查情態動詞引起的一般疑問句的答語
      [考點快憶] 回答must時,肯定答語用must,否定答語用needn't或don't have to。回答need時,肯定答語用must,否定答語用needn't。回答may時,肯定答語用may,否定答語用mustn't 或can't。
      3.考查情態動詞的意義
      [考點快憶] must “必須”;have to“不得不”;need “必須;需要”;can(could)“能;可能”;may (might) “可以;可能”;shall,will (would)“將;會;愿意;要”;should“應當”。 “had better (not) + 動詞原形”表示建議;have to / has to / had to的否定,疑問形式要借助于助動詞do / does / did。
      中考對定語從句的考查
      1.定語從句的功用和結構
      在復合句中,修飾某一名詞或代詞的從句叫做定語從句。被定從句修飾的詞叫做先行詞。定語從句必須放在先行詞之后。引導定語從句的關聯詞有關系代詞和關系副詞。例如:
      This is the present that he gave me for my birthday
      2.關系代詞和關系副詞的功用
      關系代詞和關系副詞用來引導定于從句,在先行詞和定語從句之間起紐帶作用,使二者聯系起來。關系代詞和關系副詞又在定語從句中充當一個成分。關系待客做主語,賓語,定語,關系副詞可作狀語。
      <1>. 作主語:關系代詞在定語從句中作主語時,從句的謂語動詞的人稱和數須和先行詞一致。例如:
      I don’t like people who talk much but do little.
      The cars which are produced in Hubei Province sell very well.
      <2>. 作賓語:She is the person that I met at the school gate yesterday.
      The book that my grandmother gave me is called “The Great Escape”.
      <3>. 作定語
      關系代詞whose在定語從句中作定語用。例如:
      What’s the name of the young man whose sister is a doctor?
      The girl whose father is a teacher studies very hard.
      <4>. 作狀語 
            I’ll never forget the day when I first came to Beijing.
      三. 各個關系代詞和關系副詞的具體用法
      1. who 指人,在定語從句中作主語。例如:
      The person who broke the window must pay for it.
      The boy who is wearing the black jacket is very clever.
      2. whom指人,在定語從句中作賓語。例如:
      Do you know the young man (whom) we met at the gate?
      Mr Lee (whom) you want to see has come.
      3. whose 指人,在定語從句中作定語。例如:
      The girl whose mother is ill is staying at home today.
      I know the boy whose father is a professor.
      4. which指物,在定語從中作主語或賓語。例如:
      A dictionary is a book which gives the meaning of words.
      Here is the book (which) the teacher mentioned yesterday.
      5. that多指物,有時也指人,在定語從句中作主語或賓語。例如:
      I’ve read the newspaper that(which) carries the important news.
      Who is the person that is reading the newspaper over there?
      6. when 指時間,在定語從句中作狀語。例如:
      I’ll never forget the time when we worked>He arrived in Beijing
      7. where 指地點,在定語從句中作狀語。例如:
      This is the house where we lived last year.
      The factory where his father works is in the east of the city.
      四. 關系代詞 whom, which 在定語從句中作介詞賓語時,可以和介詞一起放于先行詞與定語從句之間,有時為了關系緊湊也可以將 whom 與 which 與先行詞緊挨著書寫,而將介詞置于定語從句的后面,如:
      That was the room in which we had lived for ten years. = That was the room which we had lived in for ten years.
      五. 具體使用時還要注意下列問題:
      1. 只能使用that,不用which 的情況:
      (1) 先行詞是all, few, little, nothing, everything, anything 等不定代詞時。
      All that he said is true.
      (2) 先行詞被only, no, any, all,等詞修飾時。
      (3) 先行詞是序數詞或被序數詞修飾的詞。例如:
      He was the second (person) that told me the secret.
      (4) 先行詞是形容詞最高級或被形容詞最高級修飾的詞。
      This is the best book (that) I have read this year.
      (5) 先行詞既包括人又包括物時。例如:
      He talked about the people and the things he remembered.
      2. 只能用which,不用that 的情況:
      (1) 在非限制性定語從中。例如:
      The meeting was put off, which was exactly what we wanted.
      (2) 定語從句由介詞+關系代詞引導,先行詞是物時。例如:
      The thing about which he is talking is of great importance.
      考查的主要形式是單項填空、完型填空、短文填空和完成句子。閱讀理解和書面表達肯定也要用到定語從句。
