Unit 4 Natural Disasters Reading fr Writing ——概要写作
概要是一篇较长文章本质思想的简洁重述，它要求用尽量少的语言对原文的主旨进行复述。概要不是简单的换句话说，更不是评论，而是作者思想中最基本部分的准确再现。
《考试说明》中规定概要写作阅卷时按5个档次给分，其中最高档次第五档(21-25 pints)的评分标准是：1.理解准确，涵盖全部要点；2.能准确使用相应的语法结构和词汇；3.完全使用自己的语言；4.有效使用了语句间的连接成分，使完成的概要结构紧凑。
1.定位——查找核心信息通过阅读定位语篇的核心信息，包括核心单词，核心短语和核心句子。(句子为主，以单词和短语为辅)2.改写——用自己的语言改写信息在核心信息的基础上进行语言表达形式的改写，对原文的语言表达形式尽可能实现大规模的改变。改写过程中，原则上字数不超过原句，不改变原文的逻辑结构，充分考虑语句压缩。
3.核查——添加关联词，检查句子的连贯性核查句子的连贯性。核查标点、语法、连接词及字数，优先考虑使用较短的连接词，如：but，then，later等。

We’ve reached a strange—sme wuld say unusual—pint. While fighting wrld hunger cntinues t be the matter f vital imprtance accrding t a recent reprt frm the Wrld Health Organizatin(WHO), mre peple nw die frm being verweight than frm being underweight. It’s the gd life that’s mre likely t kill us these days.Wrse，nearly 18 millin children under the age f five arund the wrld are estimated t be verweight. What’s ging n?
We really dn’t have many excuses fr ur weight prblems. The dangers f the prblem have been drilled int us by public-health campaigns since 2001 and the message is getting thrugh—up t a pint.
In the 1970s, Finland, fr example, had the highest rate f heart disease in the wrld and being verweight was its main cause. Nt any mre. A public-health campaign has greatly reduced the number f heart disease deaths by 80 percent ver the past three decades.Maybe that explains why the percentage f peple in Finland taking diet pills dubled between 2001 and 2005, and dctrs even ffer surgery f remving fat inside and change the shape f the bdy. N wnder it ranks as the wrld’s mst bdy-cnscius cuntry.
We knw what we shuld be ding t lse weight—but actually ding it is anther matter. By far the mst ppular excuse is nt taking enugh exercise. Mre than half f us admit we lack willpwer.
Others blame gd fd. They say: it’s just t inviting and it makes them vereat. Sme als blame their parents—their genes. But unfrtunately, the parents are wrnged because they’re nrmal in shape, r rather slim.It’s a similar stry arund the wrld, althugh peple are relatively unlikely t have tried t lse weight. Parents are eager t see their kids shape up. D as I say—nt as I d.
