《學(xué)海無涯圖作舟》PPT課件

學(xué)海無涯“圖”作舟海南華僑中學(xué) 劉蓮 看一看：視覺印象 比一比：文字和圖像 請閱讀下面一段文字：神經(jīng)元神經(jīng)元（neuron）是一種高度特化的細(xì)胞，是神經(jīng)系統(tǒng)的基本結(jié)構(gòu)和功能單位，它具有感受刺激和傳導(dǎo)興奮的功能。神經(jīng)元由胞體和突起兩部分構(gòu)成。胞體的中央有細(xì)胞核，核的周圍為細(xì)胞質(zhì)，胞質(zhì)內(nèi)除有一般細(xì)胞所具有的細(xì)胞器如線粒體、內(nèi)質(zhì)網(wǎng)等外，還含有特有的神經(jīng)原纖維及尼氏體。神經(jīng)元的突起根據(jù)形狀和機(jī)能又分為樹突dendrite和軸突axon。樹突較短但分支較多，它接受沖動(dòng)，并將沖動(dòng)傳至細(xì)胞體，各類神經(jīng)元樹突的數(shù)目多少不等，形態(tài)各異。每個(gè)神經(jīng)元只 發(fā)出一條軸突，長短不一，胞體發(fā)生出的沖動(dòng)則沿軸突傳出。 比較得出的數(shù)字1：100萬右腦的信息存儲量是左腦的100萬倍。1：1000總的來說，大腦對圖像的加工記憶能力是文字的1000倍。 想一想，猜一猜：思維導(dǎo)圖什么是思維導(dǎo)圖？ 讓你更有效地把信息放進(jìn)你的大腦，或是把信息從你的大腦中取出來。思維導(dǎo)圖可以用到哪里？ 記筆記、背誦、整理、做計(jì)劃、創(chuàng)作、展示 練一練，試一試：思維演習(xí)思維導(dǎo)圖在英語學(xué)習(xí)中的應(yīng)用 圖憶法背英語課文新概念英語2第1課 Last week I went to the theatre. I had a very good seat. The play was very interesting. I did not enjoy it. A young man and a young woman were sitting behind me. They were talking loudly. I got very angry. I could not hear the actors. I turned round. I looked at the man and the woman angrily. They did not pay any attention. In the end, I could not bear it. I turned round again. I cant hear a word! I said angrily. Its none of your business, the young man said rudely. This is a private conversation! 賽一賽，驗(yàn)一驗(yàn)：實(shí)踐出真知 The Olympic Games will be held in our country in four years time.
