增强背诵记忆的方法

? 勤动手指

锻炼手指功能可健脑益智,促进思维。学做针线活,或手拿两个核桃,不停地在手中转动或练习绘画,长期坚持都会有健脑作用。

? 适当慢跑

下肢活动可刺激对侧大脑皮层的活动,起到健脑作用。慢跑可以持续刺激大脑创造新的神经细胞生成以及脑内血管的健東运转。

? 多听音乐

听音乐能改善脑力,缓和心境,平稳情绪。音乐可以影响听觉,进而刺激大脑皮层兴奋,保持大脑活力。

? 放开嗓子大声朗读

朗读的过程是把视觉的刺激反馈给听觉,并加以确认,还会用到唇、舌、喉等身体的各个部位。这样一来,朗读就能充分调动身体,带给大脑的刺激比默读多得多,记忆也更加深刻。

? 多回想细节

读书或听人说话的时候,要不时停下来回想刚才读到或者听到的内容,想得越详细越好。大脑储存这些信息时,细节越多,记忆效果越好。

? 锻炼观察力

这是防止健忘最好的方式之一。每次去一个新地方时,在心中记下房间内10件东西摆放的位置,等你离开的时候,再仔细回想那10件东西的位置。

? 对自己说“肯定能行”

脑不会马上发生变化,不要一下子设定过高的目标。通过把目标说出来、写下来等方法,能够强化意识,这是你激活脑的第一步。

While he was doing his homework, the telephone rang. As he walked along the lake, he sang happily. He had learned a little Chinese before he came to China. After he finished middle school, he went to work in a factory.

(2)在时间状语从句里,通常不用将来时态,用现在时态表示将来的动作或状态。例如: Ill ring you up as soon as I get to New York. I will tell him everything when he comes back. He wont believe it until he sees it with his own eyes. (3)在带有till或until引导的时间状语从句的主从复合句里,如果主句用肯定式,其含义是"一直到......时",谓语动词只能用延续性动词。如果主句用否定式,其含义是"直到......才......", "在......以前不......", 谓语动词可用瞬间动词。例如: The young man read till the light went out. Lets wait until the rain stops. We wont start until Bob comes. Dont get off until the bus stops. 2. 条件状语从句 (1)条件状语从句通常由if, unless引导。例如: What shall we do if it snows tomorrow? Dont leave the building unless I tell you to. (2)在条件状语从句里,谓语动词通常用现在时态表示将来的动作或状态。例如: Ill help you with your English if am free tomorrow. He wont be late unless he is ill. (3)"祈使句 + and (or)+ 陈述句" 在意思上相当于一个带有条件状语

初三英语语法知识点归纳

初中英语语法速记口诀大全 很多同学认为语法枯燥难学,其实只要用心并采用适当的学习方法,我们就可以愉快地学会英语,掌握语法规则。笔者根据有关书目和多年教学经验,搜集、组编了以下语法口诀,希望对即将参加中考的同学们有所帮助。 一、冠词基本用法 【速记口诀】 名词是秃子,常要戴帽子, 可数名词单,须用a或an, 辅音前用a,an在元音前, 若为特指时,则须用定冠, 复数不可数,泛指the不见, 碰到代词时,冠词均不现。 【妙语诠释】冠词是中考必考的语法知识之一,也是中考考查的主要对象。以上口诀包括的意思有:①名词在一般情况下不单用,常常要和冠词连用;②表示不确指的可数名词单数前要用不定冠词a或an,确指时要用定冠词the;③如复数名词表示泛指,名词前有this,these,my,some等时就不用冠词。 二、名词单数变复数规则 【速记口诀】 单数变复数,规则要记住, 一般加s,特殊有几处: 末尾字母o,大多加s, 两人有两菜,es不离口, 词尾f、fe,s前有v和e; 没有规则词,必须单独记。 【妙语诠释】①大部分单数可数名词变为复数要加s,但如果单词以/t?蘩/、/?蘩/、/s/发音结尾(也就是单词如果以ch,sh,s,x等结尾),则一般加es;②以o结尾的单词除了两人(negro,hero)两菜(tomato,potato) 加es外,其余一般加s;③以f或fe结尾的单词一般是把f,fe变为ve再加s;④英语中还有些单词没有规则,需要特殊记忆,如child—children,mouse—mice,deer—deer,sheep—sheep,Chinese—Chinese,ox—oxen,man—men,woman—women,foot—feet,tooth —teeth。 三、名词所有格用法 【速记口诀】 名词所有格,表物是“谁的”, 若为生命词,加“’s”即可行, 词尾有s,仅把逗号择; 并列名词后,各自和共有, 前者分别加,后者最后加; 若为无生命词,of所有格, 前后须倒置,此是硬规则。 【妙语诠释】①有生命的名词所有格一般加s,但如果名词以s结尾,则只加“’”;②并列名词所有格表示各自所有时,分别加“’s”,如果是共有,则只在最后名词加“’s”;③
