从句时态口诀?

从句时态口诀?

  [宾语从句歌诀]
  宾语从句三姊妹,that,if/whether,wh-/how展风采。
  展风采有三关,引导词、语序、时态在把关。
  主从时态要一致,陈述语序永不变。
  陈述请你选that,疑问需用if/whether连。
  特殊问句作宾从,原来问词不用换。
  三关过后莫得意,人称、标点需注意。
  留意变脸的if/when,从句的简化记心间。
  [歌诀解码]
  一、三姊妹
  宾语从句根据引导词的不同可分为三种类型:
  1. 由that引导的宾语从句。如:
  We knew (that)we should learn from each other.
  2. 由if/whether引导的宾语从句。如:
  Please tell me if/whether you have been to America.
  3. 由who,where,how等连接代词或连接副词引导的宾语从句。如:
  Can you tell me how I can get to the nearest post office
  二、三关
  1. 引导词关
  如果从句是陈述句,引导词用that(that在口语或非正式文体中常省略);如果从句是一般疑问句,引导词用if/whether;如果从句是特殊疑问句,引导词用由疑问词转换而来的疑问代词/副词。
  2. 语序关
  ①陈述句变为宾语从句,语序不变,即仍用陈述语序。如:
  He is an honest boy. The teacher said. →The teacher said(that)he was an honest boy.
  ②一般疑问句和特殊疑问句变为宾语从句,语序变为陈述语序。如:
  Does he work hardI wonder.→I wonder if/whether he works hard.
  When did he leaveI dont know. →I dont know when he left.
  3. 时态关
  ①如果主句是现在的时态,从句的时态可根据实际情况而定。如:
  I have heard(that)he will come back next week.
  ②如果主句是过去的某种时态,那么从句的时态一定要用过去的某种时态。如:
  He said(that)there were no classes yesterday.
  注意:如果宾语从句表述的是客观真理、自然现象等时,不管主句是什么时态,从句都要用一般现在时。如:
  He said that light travels much faster than sound.
  三、人称的变化和标点的使用
  1. 从句的主语如果是第一人称,变为宾语从句则与主句的主语一致;如果是第二人称,则与主句的宾语一致;如果是第三人称,不用变化。如:
  “May I use your knife”He asked me. →He asked me if he might use my knife.
  “Do you know her telephone number”He asked me. →He asked me if I know her telephone number.
  2. 宾语从句的标点均由主句决定。主句是陈述句,用句号;主句是疑问句,用问号。如:
  Who will give us a talkI dont know. →I dont know who will give us a talk.
  Do you knowWhere does he live→Do you know where he lives
  四、两副面孔
  if和when既能引导时间状语从句,又能引导宾语从句。因此,遇到它们就要认真分析一下,它们究竟属于“两副面孔”的哪一副。如:
  If it rains tomorrow,I wont come.(时间状语从句)
  I dont know if it will rain tomorrow. (宾语从句)
  五、从句的简化
  1. 当主句谓语动词是find,see,watch,hear等感官动词时,从句常简化为“宾语 宾补”结构,宾补为不带to的不定式或V-ing形式。如:
  She found that the wallet lay/was lying on the ground. →She found the wallet lie/lying on the ground.
  2. 当主句谓语动词是hope,wish,decide,forget,plan,agree等,且主句主语与从句主语相同时,从句可简化为不定式结构。如:
  She agreed that she could help me with my maths. →She agreed to help me with my maths.
  3. 在连接代词/副词引导的宾语从句中,当从句主语与主句主语或间接宾语一致时,宾语从句可简化为“连接代词/副词 不定式”结构。如:
  Can you tell me how I can get to the station→Can you tell me how to get to the station

感觉动词和感官动词区别?

感官动词指表示感觉和心理状态的动词。常见的感官动词有:一个表示“感觉”(feel);两个表示“听”(listen to/hear);三个表示“让”的使役动词(let、have、make);五个表示“看”(look at/see/watch/notice/observe);以及表示“帮助”的help。口诀:一感二听三让五看半帮助。感官动词后可以用作宾语补足语的:省去to的动词不定式、现在分词以及过去分词。
1. 感官动词接不带to的不定式作宾语补足语时,强调不定式表示的动作的整个过程。例如:
I saw him steal my money.我看见他偷我的钱了。
She heard Tom go upstairs.她听见汤姆上楼了。
注意:当动词不定式在感官动词后面做宾语补足语的句子变为被动语态时,不定式的to 就不能省去。例如:
He was seen to steal my money .
2. 感官动词接现在分词作宾语补足语,强调现在分词表示的动作正在发生(即处于发生的过程中,还没有结束),或是某个反复进行的动作。例如:
Jenny could hear them arguing 能听到他们正在外面争论。
I saw a young mother kissing her child again and again.我看到那个年轻的母亲反复亲吻她的孩子。
3. 感官动词接过去分词作宾语补足语,过去分词表示的动作与宾语构成逻辑上的被动关系。例如:
I saw him punished.我看到他被惩罚了。
I felt my hand bitten.我感到手被咬了。
