馬拉松兔子（Rabbit）只是含義特殊的"黑話"，是配速員/領跑員的通俗稱呼，英文PACER，是從馬拉松詞匯PACE、即"配速"衍生而來的。他們和參賽者們一同起跑，并依照固定的速度前進，幫助賽道上的跑者了解自身速度，不至于過快或過慢于自己預設的時間。
一說兔子的發(fā)明是受獵人去追逐野兔場景的啟發(fā)，在比賽中設置配速員為目標，讓參賽者們保持在一個速度的頻道上，借此前面有人做目標而激勵選手們完賽。
02 兔子分類
隨著馬拉松賽事的發(fā)展，根據(jù)項目的不同，"配速員"大致分四種類型：
1、"場地配速員"；主要是在商業(yè)比賽中才會出現(xiàn)，在長跑項目中領跑。
2、專業(yè)配速員:這種就是在馬拉松比賽中專門為職業(yè)選手或者精英選手做領跑的，一般是引導選手沖擊更好的成績。這類專業(yè)兔子一般帶領前30公里，剩下的路程留給"主力"選手發(fā)起沖刺。
3、第三種是在馬拉松賽中帶領大眾選手按照規(guī)定時間內完賽的配速員，會設置不同時間段完賽，這種一般也是我們在賽場上最常見到的。他們需要按規(guī)定時間跑完全程。
4、有別于第三種的非官方配速員或者非專業(yè)選手的私人兔子。
5. 跑步的pb什么意思
馬拉松和跑步術語中只有PB，沒有BP。
PB的全稱是personal best（個人最好成績）。相對應的還有PW——personal worst（個人最差成績）。
馬拉松PB，就是personal best的意思，跑馬拉松的pb就是馬拉松的最好成績，如果說我這次馬拉松pb了，也就是說我跑出了我個人馬拉松的最好成績。
6. 跑步pb是什么意思的縮寫
銀行一般用PB估值，就是我們常說的市凈率，根據(jù)經驗，大銀行一般在0.7倍PB的時候，就有了很強的安全邊際，也就是說他把所有的凈資產打7折賣給你，現(xiàn)在工商銀行PB是0.74，農業(yè)銀行0.67，建設銀行0.75，中國銀行0.62，一般這4個銀行打7折的時候，就是銀行的大底，所以銀行我們還需要等一等，他可能還有最后一跌，這是對銀行做的一般的判斷。

簡筆畫是一種利用簡單的點、線、畫等符號來表現(xiàn)物象基本特性的，簡約而直觀、形象、鮮明、生動的繪畫形式。是指把復雜的形象簡單化，形體結構是繪畫最基本的要素，各種物體都有自己獨特的構成因素。
基礎知識
簡筆畫就是用最簡練的線條和平面圖形概括表現(xiàn)出物體的基本形狀和主要特征，亦可以稱減筆畫。簡筆畫不僅是一種實用性很強的通俗藝術形式，而且通過精練概括、簡中求美，以少勝多的藝術思維和造型理念，廣泛運用多種藝術造型形式，給人以物質精神的審美享受。注重圖形體現(xiàn)的象征性，這是與一般速寫的最大區(qū)別。簡筆畫看起來簡單，然而是對物象特征的概括和提煉。
簡筆畫發(fā)展
小學英語教學中的簡筆畫稱為“教學簡筆畫”。教學簡筆畫不同于一般繪畫，它必須伴隨著教學內容而存在，它的畫面要和教學語言融為一體。它不在于寫實，只在于寫意傳神，并且一揮而就，一學就會，不需要什么高深的繪畫技巧，只需要稍加練習便可掌握。
它是教學中直觀生動的快捷演示，即教師在教學中利用黑板，以凝練、概括的圖示形式，把文章重難點、中心意義顯示出來，使學生更直觀、形象地理解文章的重點、中心意義顯示出來，使學生更直觀、形象地理解文章內容的一種板書形式。
簡筆畫在小學英語教學中的運用能配合素質教育的實施和發(fā)展，不僅幫助學生靈活地學習運用英語還有利于學生完善自我，幫助培養(yǎng)創(chuàng)新精神，實踐能力和審美情趣。而且使用起來非常方便，隨時隨地都可信手拈來，隨需隨畫，對教學尤為適用。
作為教師如何充分發(fā)揮簡筆畫的藝術特色，使其和小學英語教學完美結合。始終要注意貫徹“畫中有話，話中有畫”這一教學原則。
教學情景
情景教學法適合低年級學生的學習規(guī)律，有利于培養(yǎng)學習興趣和語言能力。兒童需要在輕松、快樂、得到鼓勵的環(huán)境中學習。針對現(xiàn)在的多數(shù)學校來說，與課文配套的教學圖片還不齊全，有些農村小學甚至都不具備這些教學圖片，都拿實物來也不太實際。
教師在教學活動中，無論是呈現(xiàn)新知識，還是鞏固舊知識，都應盡最大努力，創(chuàng)造一個快樂、有趣、有意義的課堂語言氣氛，而通過簡筆畫學單詞，情況將會很不一樣，它能為教學內容提供生動具體的情景，然后可以圍繞這些情景去展開一系列的教學，使學生身在教室便有一種置身于英語文化中的感覺。
教學中常常會遇到一些無法用實物或場景表現(xiàn)的內容，則可以通過簡筆畫，配上一些表情、手勢、動作等，使學生明白句子的意思和使用場合，達到句意相連，運用自如的效果?？繉W生們抽象地死記硬背來掌握，枯燥而乏味，效果也自然不好。
