1。 头绪分明,脉络清楚
写好记叙文,首先要头绪分明,脉络清楚,明确文章要求写什么。要对所写的事件或人物进行分析,弄清事件发生、发展一直到结束的整个过程,然后再收集选取素材。这些素材都应该跟上述五个“ W ”和一个“ H ”有关。尽管不是每篇记叙文里都必须包括这些“ W ”和“ H ”,但动笔之前,围绕五个“ W ”和“ H ”进行构思是必不可少的。
2。 突出中心,详略得当
在文章的框架确定后,对支持故事的素材的选取是很关键的。选材要注意取舍,应该从表现文章主题的需要出发,分清主次,定好详略。要突出重点,详写细述那些能表现文章主题的重要情节,略写粗述那么非关键的次要情节。面面俱到反而使情节罗列化,使人不得要领。这一点是写好记叙文要解决的一个基本问题,也需要一定的技巧。如:
One night a man came to our house and told me, "There is a family with eight children。 They have not eaten for days。" I took some food with me and went。
When I finally came to that family, I saw the faces of those little children disfigured (破坏外貌) by hunger。 There was no sorrow or sadness in their faces, just the deep pain of hunger。
I gave the rice to the mother。 She divided the rice in two, and went out, carrying half the rice。 When she came back, I asked her, "Where did you go?" she gave me this simple answer, "To my neighbors — they are hungry also!"
3。 用活语言,准确生动
记叙文要用具体的事件和生动的语言对人、事、物加以叙述。一篇好的记叙文的语言既要准确、生动,又要表现力强,这样才能把人、事描写得具体生动,其可读性才强。试比较下面一篇例文修改的前后效果。
原文:
One day Xiaoqiang was wandering away。 He was soon lost among people and traffic。 He could not find the way back home and started crying。 Just then, two young students who were passing by found him standing alone in front of a shop and crying。 They went up to Xiaoqiang and asked him what had happened。 Xiaoqiang told them how he got lost and where he lived。 The two students decided to take him home。 Mother was pleased to see Xiaoqiang come back safe and sound。 She invited the two students into the house and gave them some money, but they didn't take it。 She served them with tea but they left。
修改后:
The other day, five-year-old Xiaoqiang left home alone and wandered happily in the street。 After some time, he felt hungry so he wanted to go back home。 But he found he was lost among the crowded people and heavy traffic。 When he could not find the way home, he started and crying。 Just then, two young students who were passing by from school found him sanding crying in front of a shop。 They immediately went up to him。
"Little boy, why are you standing here crying?" they asked。
"I want Mom, I go home。" said the boy, still crying。
"Don't worry, we'll send you home。"
And they spent the next two hours looking for the boy's house。 With the help of a policeman, they finally found it。
When the worried mother saw her son come back safe and sound, she was so thankful and she invited the students into her house。 Gratefully, she offered them some money, saying it was a way to express her thanks, but the young students firmly refused it and left without even a cup of tea。

1、(2分,意近即可酌情给分:引起读者的阅读兴趣,概括了热饮热食的危害,自然地引出了下文。
2、(5分:危害有:容易发生癌变(1分;不利于饮食的消化吸收(1分;难以细品食物的美味(1分。
途径(2分:调查发现、病理研究
3、(第一问2分:①举例子、②列数字 (第二问2分。选项不给分,但不写选项扣0.5分答案略
4、(3分:不能删去(1分。因为“可能”一词说明癌症除了与热饮热食有关外,还与其他因素有关,如果去掉“可能”就排除了其他因素,与原文不符(2分。
口腔食道都怕烫,热饮热食有损伤。上皮增生会恶变,吃饭喝汤不要忙。
温度对人具有诸多微妙作用。生命在进化中都有自身最适合的温度,进化程度越高,要求最佳适宜温度越严格。人体体温在37。C左右时,代谢活动处于最佳状态,人体细胞对高温的耐受性比低温差。热对肿瘤细胞也产生微妙的生物学作用,许多试验证明,肿瘤细胞的致死温度临界点为42.5。C~43。C,在此温度范围内,延长加温时间可抑制肿瘤细胞生长,由此产生了温热疗法治疗肿瘤。
但是事物都具有两面性。流行病学调查发现,一些地区的食管癌、贲门癌、口腔癌又可能与热饮热食有关,就是说有可能某些黏膜上皮的肿瘤是“烫”出来的。我国新疆哈萨克族居住的地区喜欢饮用热奶茶,一日数遍;东南沿海潮汕地区的居民喜喝“功夫茶”,且要趁热饮用;太行山区的人们习惯于趁热喝大碗粥。①这些地区都是我国食管癌的高发区。当然,肿瘤的发生原因复杂,并非单一因素,流行病学调查,太行山区成为食管癌高发区除热食外,还与饮食特点如粗、快、硬等有关。
研究发现,人体在37。C左右的情况下,口腔和食管的温度多在36.5。C~37.2。C,最适宜的进食温度在10。C~40。C左右,一般耐受的温度最高为50。C~60。C。当感到很热时,温度多在70。C左右。②经常热食的人,在温度很高的情况下也不觉得烫,但是在接触75。C左右的热食、热饮时,娇嫩的口腔、食管黏膜会有轻度灼伤,灼伤的黏膜表层会及时脱落、更新,基底的细胞会迅速增生、更新、补充、,久而久之,增生的细胞速度如异常加快或在不良刺激下发生变异,最终产生不良后果。另外,由于黏膜在热刺激不断增加的情况下会增厚,增厚的黏膜受热刺激反应会越来越不敏感,加之食管黏膜的神经反射本来就很迟纯,这样会越来越不怕热,越不怕热会越敢吃烫的东西,而吃得越烫,口腔黏膜会越增厚。如此恶性循环,人会不由自主地接受越来越严重的灼伤刺激。这种刺激带来的损伤还有可能引起久治不愈的食管炎,这种食管炎有时伴有间变细胞,有人提示这有可能是癌前病变之一。研究人员发现,食管癌往往合并有食管炎,食管炎往往比食管癌早10年。
热饮热食不但与肿瘤的发生有关,而且对食物的消化吸收也不利。食物太烫,在口腔存在时间偏短,刺激唾液分泌减少,以及唾液与食物混合过程不充分,这不利于饮食的消化吸收。另外,温热刺激能掩盖味觉的充分体验,往往难以细细品味各种食物的美味。
饮食过烫,不论从防癌或一般饮食卫生角度看,都属于不良的生活习惯。应努力纠正,尤其是那些有食管贲门癌家族史的人,更应早日改弦易辙。
清淡温凉吃美味,食不过烫保平安。

I was born in a beautiful town with high mountains around it.The mountains are covered with all kinds of green bamboo.Through the town runs a small stream.It’s said that a new railway is going to be built to the east of the town and a bamboo factory to the west.All the children of the school age can go to school.If anyone is ill,he can go to see the doctor in the newly-built hospital.People in the town are hard-working and never take the backwardness lying down.Though they are having a richer and better life,they are not satisfied with what they have got.They are working hard to build their town into a modern one.
