(2)Which of the following words is closest in meaning to the underlined word in the last paragraph? (3)The underlined word “ ” in Paragraph 2 can best be replaced by “ ”. (4)What does the phrase “ ” in Paragraph 1 mean?,重点词汇,重点句型,重点语法,功能,走近高考,拓展阅读,【典题例析】(2016全国高考,C篇) I am Peter Hodes,a volunteer stem cell courier.Since March 2012,Ive done 89 tripsof those,51 have been abroad.I have 42 hours to carry stem cells(干细胞) in my little box because Ive got two ice packs and thats how long they last.In all,from the time the stem cells are harvested from a donor(捐献者) to the time they can be implanted in the patient,weve got 72 hours at most.So I am always conscious of time.,重点词汇,重点句型,重点语法,功能,走近高考,拓展阅读,Which of the following can replace the underlined word “courier” in Paragraph 1? A.provider B.delivery man C.collector D.medical doctor 解析:B 词义猜测题。根据本段中的“ Ive done 89 trips”和“I have 42 hours to carry stem cells in my little box”以及下文中的内容可知作者是运送干细胞的人,也就是delivery man。故选B项。,重点词汇,重点句型,重点语法,功能,走近高考,拓展阅读,2.句意猜测题 句意猜测题大多考查一个句子的寓意,而非字面含义,且与文章主旨或段落主题密切相关。做此类题的常用方法如下: (1)阅读文章,对句子进行语法和词义上的准确分析,并依据文章主旨或段落主题深层次地理解句子含义。 (2)将所理解的句意和所给选项进行比较。一般来说,正确选项的意思与原句的意思相同,只不过是用了其他的英语词汇表述出来而已。,重点词汇,重点句型,重点语法,功能,走近高考,拓展阅读,常见的设题形式: (1)The underlined sentence in the last paragraph means “ ”. (2)What does the underlined sentence in Paragraph 4 mean? (3)Which of the following best explains the underlined part in the last paragraph?,重点词汇,重点句型,重点语法,功能,走近高考,拓展阅读,3.代词指代题 代词指代题旨在考查考生对阅读素材的理解和把握能力。文章中的代词it,that,he,him,them 等可以指上文提到的人或物,其中it和that还可以指一件事。有时代词指代的对象相隔较远,要认真查找;也有时需要对前面提到的内容进行总结,才能得出代词所指代的对象。做此类题可采用下列方法: (1)准确理解画线部分代词所在的句子的意思。如果不能解决问题,那么还要准确理解该句子前一两个句子的意思。 (2)理解句子的意思后,要将注意力放在画线代词所在句子的前半部分的名词或名词性短语上。如果不能解决问题,则应注意该句子前一两个句子中的名词或名词性短语。 (3)将确定的答案替代画线部分的代词,看句子的意思是否通顺,逻辑关系是否成立。,重点词汇,重点句型,重点语法,功能,走近高考,拓展阅读,【典题例析】 (2016全国高考,C篇) .

The side effects of global warming are alarming.A warmer global climate melts the ice caps,raising sea levels.What is more,it disturbs weather patterns,causing droughts,severe storms and hurricanes.People suffer a lot from disasters relevant to global warming. Here is another discovery about global warming.,重点词汇,重点句型,重点语法,功能,走近高考,拓展阅读,Global warming could make humans shorter,warn scientists who claim to have found evidence that it caused the worlds first horses to shrink nearly 50 million years ago. In fact,a team from the universities of Florida and Nebraska says it has found a link between the Earth heating up and the size of mammalshorses,in this case,the last time the world heated up. The scientists used fossils to follow the evolution of horses from their earliest appearance 56 million years ago. As temperatures went up their size went down,and vice versa;at one point they were as small as a house cat,said Dr Jonathan Bloch,curator of the Florida Museum of Natural History. The scientists say that the current warming could have the same effect on mammalsand could even make humans smaller.,重点词汇,重点句型,重点语法,功能,走近高考,拓展阅读,“Horses started out small,about the size of a small dog like a miniature schnauzer.Whats surprising is that after they first appeared,they then became even smaller and then dramatically increased in size,and that exactly corresponds to the global warming event,followed by cooling. “It had been known that mammals were small during that time and that it was warm,but we hadnt understood that temperature specifically was driving the evolution of body size,” Dr Bloch said in the “Science” journal.,重点词汇,重点句型,重点语法,功能,走近高考,拓展阅读,译文 全世界的人或许觉得近几年气候正逐步变得越来越暖和。过去降雪丰富的地方已经经常经历无雪的冬天了。干旱在一些较干的地区持续时间更长了。人们发现,没有空调他们几乎无法在炎热的夏日里工作或入睡。 全球变暖的副作用在敲响警钟。更暖和的气候使冰块融化,海平面上升。而且,全球变暖扰乱了天气模式,导致干旱、严重的暴雨和飓风。与全球变暖有关的灾难使人们受了很多苦。 这里有关于全球变暖的另一个发现。 科学家警告说,全球变暖可能会使人类变矮。科学家宣称已经找到证据:近5000万年前全球变暖就曾让世界上最早的马个头变小。,重点词汇,重点句型,重点语法,功能,走近高考,拓展阅读,事实上,来自佛罗里达州和内布拉斯加州的大学的一支研究团队称,他们已经找到地球变暖和哺乳动物个头之间的联系。这一案例中马变矮的现象是上一次全球变暖时发生的。 科学家用化石来追溯马从5600万年前诞生至今的进化历程。 随着气温的上升,马的个头变小;反之,气温下降,马的个头就变大。佛罗里达自然历史博物馆馆长乔纳森布洛赫博士说,它们曾一度像家猫那么小。 科学家称,当前的全球变暖可能也会对哺乳动物产生同样的影响,甚至可能会让人类的个子也变小。 布洛赫博士在科学杂志中写道:“马最初的个头很小,和一只小狗的个头差不多,大约也就像一只迷你型雪纳瑞犬那么大。令人惊讶的是,在马诞生后过了一段时间,它们的个子变得更小,之后个头又显著变大,而这些变化与全球变暖既而变冷正好是相对应的。,重点词汇,重点句型,重点语法,功能,走近高考,拓展阅读,“我们已经知道哺乳动物在那个时期个头较小,而那个时期气候也较暖,但我们还未意识到正是温度驱动着身体大小的进化。” 词海拾贝 1.abundantbndnt adj.丰富的,大量的 2.mammal mml n.哺乳动物 3.curator kjreIt n.馆长 4.quote kwt v.引用 5.miniature schnauzer迷你型雪纳瑞犬 6.correspond krspnd v.符合;相一致,重点词汇,重点句型,重点语法,功能,走近高考,拓展阅读,理解诱思 1.What has caused some ice caps to melt according to the passage?
