lective breeding towards today’s super cob (超級(jí)玉米 ) were probably fortuitous(偶然的 ). The simple act of gathering the tiny cobs would tend to select those in which the kernels fall out least readily: if the cobs are taken back to the village to be dried, the kernels that survive the journey will be those which stick most tenaciously in the cob. Once people had taken the conscious step of sowing seeds it was then just a matter of experience and insight to improve the crops by using seeds from the healthiest plants of the previous season. Whether, initially, deliberate sowing followed a conscious experiment, or was the result of keen observation of accidentally spilled seeds that had been meant for food, we shall never know. The event must have occurred independently in many places and in many different ways, sometimes perhaps accidentally and sometimes by design. And the circumstances for beginning regular rootcropping must also have differed. The previous focus of any hunting and gathering munity must, of course, have influenced the style of agriculture it adopted. 以下列問(wèn)題為例: 61. At the time of the advent of agriculture, the global population _______ 很 好,你很快就在第二段看到 “the advent of agriculture”,而且前面有一個(gè)轉(zhuǎn)折“however”,這個(gè)詞無(wú)論什么時(shí)候都是那么讓人振奮,其后緊跟著一個(gè)副詞“sparsely”,這個(gè) 時(shí)候你一定心跳很快,因?yàn)楦痹~和形容詞是多么重要的細(xì)節(jié)啊。 3. 其他:如選項(xiàng)出現(xiàn)絕對(duì)詞匯( every/all)一般為錯(cuò)誤解。找到敏感區(qū)域再回頭看選項(xiàng)。注意,應(yīng)先做有特征的題,以減少浪費(fèi)在閱讀上的時(shí)間。 2. 醫(yī)學(xué)考博閱讀理解解題方法( blackknightca 原創(chuàng)) 1. 先讀問(wèn)題,再讀原文。 有多余的時(shí)間(為了考高分,你最好有這時(shí)間),不妨聽聽歷年 TOEFL考試聽力,非常有用,沒(méi)準(zhǔn)兒還出現(xiàn)原題哩。為穩(wěn)妥起見,在考前也參加了蔣教授的輔導(dǎo)班,不過(guò),聽完之后有個(gè)感覺,也即:應(yīng)試技巧其實(shí)和托福差不多(聽另外的人講也和四、 六級(jí)差不多)。 更多的經(jīng)驗(yàn)體會(huì)及考試資料歡迎與我聯(lián)系。 平時(shí)考聽力多有預(yù)讀題干及選項(xiàng)的習(xí)慣,蔣躍老師也是這么教的,但有些考場(chǎng)監(jiān)考嚴(yán),正式 開考前根本不讓打開信封,這樣就沒(méi)時(shí)間預(yù)讀題干及選項(xiàng),這樣怎么辦,考前都要有所準(zhǔn)備。 某高人(不是 olian)自述如下: 今 年參加考博英語(yǔ)成功達(dá)到 80 分,原我的英語(yǔ)基礎(chǔ)一般,也就 65 分水平,參加蔣躍教授輔導(dǎo)班及自己對(duì)路的復(fù)習(xí)方法是提高成績(jī)的關(guān)鍵,在此有很多經(jīng)驗(yàn)與心得體 會(huì),愿與未來(lái)考博者交流。這里把考試時(shí)要注意的與大家做一交流: 聽力很多學(xué)校是采用,放錄音機(jī)或在階梯大教室從大音箱里播放英語(yǔ)聽力(如北京的解放軍 軍事醫(yī)學(xué)科學(xué)院, 301 醫(yī)院等),其語(yǔ)音清晰度比我們平時(shí)多采用的耳機(jī)聽英語(yǔ)要差很多,所以平時(shí)要加強(qiáng)音響、錄音機(jī)播放英語(yǔ)聽力的練習(xí),即使你了解要考學(xué) 校的聽力考試所用設(shè)備,也要這 樣做,因?yàn)橛行﹩挝豢赡芘R時(shí)突然改變考場(chǎng),聽力設(shè)備也隨之變化(如今年的 301 醫(yī)院,原在本院戴耳機(jī)聽,改在軍醫(yī)學(xué)院放錄音 及階梯教室從大音響里播放),有些考生平時(shí)沒(méi)有這方面練習(xí)者,不適應(yīng),因此聽力丟分不少,聽力為英語(yǔ)考試的第一部分且占 30 分的高分,如考不好直接影響到 繼續(xù)考下去的信心、情緒、發(fā)揮及成績(jī),有些就產(chǎn)生了放棄的心理。很多老師教不到的現(xiàn)實(shí) 情況,有時(shí)卻成為了你考試是否成功的關(guān)鍵。 我 也是今年考博,英語(yǔ) 82 分。本人英語(yǔ)底子不差,所以也感受不到輔導(dǎo)班所起的突飛猛進(jìn)的效果,但關(guān)于醫(yī)學(xué)博士英語(yǔ)考試也有一點(diǎn)心得也許對(duì)大家有用: 蔣躍的模擬題和仿真聽力還是比較有用,為有效利用有限的資料,建議用另外的紙做題和筆記,不在書上作記號(hào),一套題做了之后 隔段時(shí)間再做,你會(huì)發(fā)現(xiàn)自己有些 題目原來(lái)做對(duì)了現(xiàn)在卻錯(cuò)了,反之亦然,在對(duì)錯(cuò)反復(fù)間加深印象最終才會(huì)掌握;反復(fù)做題也是熟悉題型和知識(shí)范圍的好方法。 考前一定要在規(guī)定的時(shí)間內(nèi)寫幾篇作文(蔣教授在輔導(dǎo)班上花了大量的時(shí)間讓我們寫作文,這點(diǎn)確實(shí)不錯(cuò))。如問(wèn)題中有明顯特征,如大寫字母,數(shù)字等,可到原文尋找 對(duì)應(yīng)點(diǎn)。 2. 接著你只好認(rèn)命地從頭開始閱讀,當(dāng)然是帶著問(wèn)題。注意, 1 不要自行引申; 2 文中沒(méi)提到的是錯(cuò)誤選項(xiàng); 3 對(duì)不確定的選項(xiàng),在敏感區(qū)域找關(guān)鍵詞,一般情況下是同義詞或意思相對(duì)應(yīng)的句子。 現(xiàn)以某人( SORRY,一時(shí)想不起他的名字)的模擬試題 1 為例: Part IV Reading Comprehension (30%) Passage One By about ten thousand years ago, with virtually every part of the globe populated, however sparsely, humanity was in place for the advent of agriculture. At the time, hunting and gathering was the universal means of subsistence, each band of humans exploiting the seasonal offerings of the animal and plant kingdoms of its own locality. By now the bow and arrow had been invented, as had the spear and spearthrower。那么接著讀選項(xiàng)吧,很好,你發(fā)現(xiàn)選項(xiàng) C 的 “not evenly distributed”很可愛,應(yīng)為它與 “sparsel
