对于英语的学习,需要我们花费一些时间和精力。下面是51自学小编收集整理的高中人教版英语知识点总结以供大家学习。 高中英语知识点总结 人教版(一) 虚拟条件句 条件状语从句是非真实情况,在这种情况下要用虚拟语气。 l-条件从句与现在事实不一致,句型为:If+主语十过去时,tiag+should (could,would,或might)+动词原形,例如:If l were you,1 would study hard. 2.条件从句与过去事实不一致,句型为:If+主语+had+过去分词,主语+should(could, would,或might)+have+过去分词,例如:If I had not studied hard.1would have failed in the exam last term 3.条件从句与将来事实不一致,句型为:lf+主语+should/were to+do,主语+should( could.)+原形do,例如:If l were to go to the moon one day,I could see itwith my own eyes. 注意: 1.If条件句中绝对不可出现“would”。 2-根据句中的时间状语,有时可能出现“混合虚拟”的情况,即主句可能是现在的情况,条件句也许是发生在过去的情况,但都遵守上述句型。 3.在条件句中如果出现were,had,should可省去if' 将这些词提前置于句首构成倒装,例如:w。re I to go tothe moon one clay,1 would see it with my own eyes.如果有一天我登上月球,我就可以亲眼目睹它的样子了。 高中英语知识点总结 人教版(二) 名词性虚拟语气 在表示命令、建议、要求、惊叹的名词性从句中需用虚拟语气。基本句型为:主语+should+动词原形,例如: 1.Mother insisted that John (should) go to bed atnine o'clock(宾语从句) 2.It was required that the crops (should) be:harvested at once.(主语从句) 3.The suggestion that he (should) be invited wasrejected.(同位语从句) 4.That is their demand that their wages (should) bemcreased.(表语从句) 注意:在这种句子中绝不能出现“would”“must”“could”等。 高中英语知识点总结 人教版(三) 虚拟语气在一些特殊词中的使用或含蓄条件句 1.wish后的宾语从句。 与现在愿望不一致,用主语十过去时,例如: I wi。hIwere you. 与过去愿望不一致,用主语+had+过去分词,例如:Iwish I had visited the White House whenI was in the States与将来愿望不一致,用主语+would (could)+原形。 2.It's time句型:当lt's tine后用that从句时应该为主i吾+should+动词原形或主语十过去时,例如:It,s time thatyou went to school.或It's time that you should go to schooL 3- If only引起的感叹句相当于“How I wish+宾语从句”。 (l)If only he could come.他要能来就好了。 (2)If only I had known the answer.我要早知道答案就好了。 4.WOuld rather,as if(though)引导的从句也需使用虚拟语气,表示过去的情况用过去完成时,表示现在与将来的情况用过去时,例如: (l)I'd rather you posted the letter right away. (2)She loves the children as if they were hers. 5.含蓄虚拟条件句含蓄条件句是指句中没有明显的虚拟条件句,而是利用其他手段来暗示存在虚拟条件。但是这类隐含式虚拟条件句往往都可以转化为if引导的条件句。常用来表示含蓄虚拟条件的手段有: (1)介词或介词短语。如but for,but that,without,in case of, under more favorable condition等。 (2)连词。如so that, unless, in case, supposing,lest, provided(倘若……),for fear that(唯恐),in orderthat, on condition that, if only(要是……就好了)等。 注意:lest, for fear that和in case引起的从句中谓语动词多用should+动词原形,但也可以不用虚拟语气,而用动词的陈述语气形式。例如:The foreign teacher spokeslowly in case we misunderstood him这位外籍教师说得很慢以免我们误解。 (3)通过上下文及内在含义,句中往往有but,otherwise, unfortunately等类似转折词。 without, but. but for, otherwise引起的短语或句子常暗含着含蓄条件。例如: ①Without you,1 would never know him ②But for your oooperation, we wouldn't have done it ③But that she was afraid, she would have said no. . ④i would be most glad to help you, butI am busy now. ⑤I would have come to the party yesterday, but ljwas working. ⑥I am busy now, otherwise l would do you the favor! 高中英语知识点总结 人教版(四) 副词的排列顺序: 1) 时间,地点副词,小单位的在前,大单位在后。 2) 方式副词,短的在前,长的在后,并用and或but等连词连接。 Please write slowly and carefully. 3) 多个不同副词排列:程度+地点+方式+时间副词。 注意:副词very 可以修饰形容词,但不能修饰动词。 改错:(错) I very like English. (对) I like English very much. 注意:副词enough要放在形容词的后面,形容词enough放在名词前后都可。 I don't know him well enough. There is enough food for everyone to eat. There is food enough for everyone to eat. 高中英语知识点总结 人教版(五) Who / whoever, what / whatever等的用法区别 一般说来,what/who等含特指意义,而whatever/whoever等含泛指意义,意为"无论什么/无论谁"。 It is generally considered unwise to give a child ____ he or she wants. A. however B. whatever C. whichever D. whenever 解析:答案是B,whatever引导一个宾语从句,并且作wants的宾语。这里的 whatever不能改成what,因为题意想表达的显然是"无论孩子要什么就给他/她什么事不明智的",具有泛指的概念。同时要注意,这里 whatever也不能改用no matter what,因为后者只能引导状语从句。比较下例: I can't remember at the moment who has said the words. (这里的who表特定的某人) Where, when, why等连接副词引导的名词性从句 Where, when, why等连接副词也可以引导名词性从句,使用的关键是:这个词必须符合句子的逻辑要求。 -I drove to Zhuhai for the air show last week. -Is that ____ you had a few days off? A. why B. when C. that D. where 解析:答案是A,why引导的从句作表语,同时why在从句中作原因状语。这里之所以选why,而不是when或 where等,唯一的依据便是句子的逻辑含义,及语境。 "介词+who(m)引导的宾语从句"与"介词+ whom"引导的定语从句的区别 介词后面的引导词用主格还是宾格,决定于它在宾语从句中作主语还是宾语。 It was a matter of ____ would take the position. A. who B. whoever C. whom D. whomever 解析:答案是A。这是一个含宾语从句的复合句,作介词of宾语的,是后面的整个句子,而不是宾语从句的引导词,由于这里引导词在从句中作主语,所以要用主格who(作宾语时自然要用whom)。
