初三英语(一)
一.英语学习的两条主线:动词,主从复合句关系 二.英语动词的判断: 1. 是否是非谓语动词 2. 动词的主谓关系的一致性(police) 3. 虚拟语气的使用 4. 动词主被动语态(rise) 5. 考虑动词的正确时态 三.语法讲堂---不定式 1.不定式的基本形态(以do为例) 一般式 完成式 进行式 完成进行式 主动形态 to do to have done to be doing to have been doing 被动语态 to be done to have been done ∕ ∕ 将要发生的动作 2. 不定式的一般式表示: 一种同步存在的状态 例①:Uncle Tom wants to fix the watch. (汤姆叔叔想要修这个表。) 改为被动形态:The watch needs to be fixed.(这个表需要被修。) looks 例②:The actor appears (to be)young. <系表结构> seems 3. 不定式的完成式表示相对于谓语动词而言已经完成的动作: 例①:The watch seems to have been fixed.(这块表似乎已经被修过。) 例②:The classroom seems to have been cleaned.(这间教室似乎已经打扫干净过。) 4. 不定式的进行式表示相对于谓语动词而言正在进行的动作: 例:The worker seems to be fixing the watch.(这个工人似乎正在修这块手表。) 典型结构:pretend to be doing 例①:When Father walked into the room, Tom pretended to be reading. (当父亲走进房间时,汤姆假装在看书。) 例②:孩子们假装睡着了。(翻译) be asleep 正解:Children pretends to have fallen asleep be sleeping 5. 不定式的基本用法: (1)不定式作主语: 句型:It’s + adj. + for/of + sb. + to do sth. <1>用for的情况: important impossible necessary convenient for+ sb. + to do sth. natural normal essential 例①:It’s very necessary for us to practice spoken English every day. (对于我们来说每天联系口语师非常需要的。) 例②:It’s impossible for us to return here by three o’clock. (对于我们来说要3点回到这里是不可能的。) <2>用of的情况: silly kind nice of+ sb. + to do sth. stupid foolish 例:It’s foolish of me to make the same mistake again. (对于我来说再次犯同样的错误是很愚蠢的。) (2)不定式作表语: to do sth. seem, appear to be (3)不定式在名词后作后置定语: 口诀:名词后方一根横线,十个for九个错,看到 to do选最长。 例①:I’m looking for a chair to ______. (D) A. for sitting B. for sitting on C. to sit D. to sit on 例外:tickets for tonight’s game(今晚的比赛票子) 例②:I’ll have sth. to say.(我有些东西要说。) 例③:There is nothing to worry about.(没有什么可以担心的。) 例④:The middle aged woman has six children to look after/take care of. (这个中年妇女要照顾6个孩子。) (4)不定式在句子中充当宾语: 口诀:省略回答时,to do保留to。 Would you like to…? Yes, I’d like/ love to…. would like to 相近的词组 would love to would prefer to do rather than do sth.(与其…还不如…) would rather do sth. (宁愿做…) |
