8、将不存在。文章的第二、三、四段讲述了该项研究中的具体的方法与数据统计。文章的第五、六段讲述了研究者对这个研究结果的看法与评论。文章的第七段讲述了美国疾病控制与预防中心对睡眠不足的看法。第八段进一步引证有关睡眠专家对睡眠不足带来的负面影响的看法。最后，第九段又回到该项研究发现上，告诉我们经常锻炼可以降低患那些癌症的风险及其原因。写作思路(1)熟悉文本类型，把握表述特征。通过文章第一段中的“U.S. researchers said on Monday”可知，本文是一篇科研报告。科研报告类的写作一般会在文章的开头部分交代文章的中心，然后具体介绍研究的设计、实施以及数据分析等，最后会根据相关研究发现
9、进一步展开说明研究可能会带来的影响等。通过分析文本类型及其表述特征，我们可以准确地筛选文章的中心及其各个部分的分论点。(2)理清文章结构，概括段落大意。根据(1)部分的分析，我们可以进一步的梳理文章的层次结构：第一段是文章的点题；第二至地四段是文章的数据分析；第五、六段是研究者的评论；第七、八段是引用他人的观点来进一步分析自己的发现；第九段则是进一步分析本研究。通过对文章层次的梳理，我们可以逐一罗列文章的中心及其各个分述的分论点。(3)确定表述中心，连贯表达要点。在(2)的基础上，我们可以逐一列出要表述的中心：第一段引出文章中心，即Regular exercise can reduce a w
10、omans risk of cancer, but the benefits may slip away if she gets too little sleep(要点1)；第二至四段是第一个分论点，即People who do regular physical activity are less likely to develop cancer, but those who sleep less than seven hours nightly have higher risk. (要点2)；第五、六段引出第二个分论点，即This research is quite new, so it i
11、s still unclear exactly how sleeping little may make one more susceptible to cancer.(要点3)；第七、八段引出第三个分论点，即Sleep loss may give rise to such health problems as obesity, diabetes, stroke, depression and so on. (要点4)；最后一段进一步引出研究的发现，即Regular exercises may have an active effect on the bodys hormone levels,
12、 immune function and body weight which thus may reduce the risk of cancer. (要点5)。在理清每部分的中心之后，我们可以利用有效的衔接手段，把这些要点组织成一个意义连贯的语篇。参考范文 US researchers have found that regular exercises may have an active effect on the bodys hormone levels, immune function and body weight which thus may reduce the risk of
13、cancer (要点1，要点) ,but the benefits may slip away if she gets too little sleep (要点1), especially less than seven hours nightly (要点2) which may cause such health problems as obesity, depression and so on. (要点4) However, it is still unclear exactly how sleeping little may make people more susceptible to
14、 cancer.(要点3)(76 words)范文解析 范文把要点1分为两部分并且与要点5、要点2、要点4进行整合，这样使得文章更加紧凑、言简意赅。范文把要点5放在了开头，这样先交代了regular exercises之所以能够降低患癌症的风险的原因；在这之后，用衔接词but把要点1的后半部分整合了进去，要点2正好也对要点1的后半部分进行了进一步的细化与解释；此外要点4缩写成一个which引导的定语从句，进一步说明睡眠不足带来的健康问题。最后用however引入要点3，说明了该项研究所存在的不足，这也正好符合科研报告类文章的写作特点。提炼归纳 1、关注文本的特征。缩写是对原文要点的综述，因而其
15、表达方式或陈述方式也必须与原文相符合。本文是一篇科研报告，所以在缩写部分就要点明是谁做的研究、研究的结果怎样、以及研究是如何进行的等。2、注重语义的转换。缩写很大程度上依赖于对原有的句子表达的浓缩与改写，这就需要对原文语句进行语义转换，包括使用非谓语动词短语替换原句子，或者用定语从句整合两个句子之间的关系等。范文中对要点1、2、4、5的整合就充分体现了在缩写中语义转换的重要性。3、强化整合的逻辑。要点整合涉及到事件或观点之间的时间先后、条件、因果关系等逻辑关系，因而在缩写的过程中，需充分关注各个要点之间的逻辑关系，并在此基础上对原文要点进行合理地整合。【写作演练】1.阅读下面短文，根据其内容写

You should try to keep your parents numbers in mind for

Yes, emojis have become a vital tool for communication.The emoji was first invented in Japan in the late 1990s and the word “emoji” comes from the Japanese words for “picture” and “character”. The number of different images has dramatically increased since then and now we

Professor Vyv Evans has written a book called The Emoji Code. He says, “Increasingly, what were finding is that digi

One of the reasons emojis are so interesting is that they really do enable us to express our emotional selves much more effectively.” So emojis are a sort of replacement for the visual signals or non-verbal clues we n
