【写作提示】1.审题:(1)明确故事人物:本故事中主要人物为柯斯迪和亨利;(2)厘清主要事件:柯斯迪的母亲与亨利的父亲重组了家庭,然而柯斯迪却有些难以接受。在一次舞台演出中,柯斯迪的戏服出了问题,裙子滑落,她在观众面前出糗,此时亨利及时帮助了她。2.写作要点:(1)亨利帮助柯斯迪将束带系好后,演出顺利进行;(2)柯斯迪在演出结束后向亨利真诚道谢,发自内心地接纳了亨利。【参考范文】Then Henry, beside Kirstie, came to her aid. He fixed her costumetying a fancy knot in the drawstring. To distract the audience's attention,he even made a joke about Kirstie, s "not"knowing knots, which madethe audience laugh again. But this time, the laugh felt good. Thanks toHenry's great help, Kirstie got through the rest of the play with delight andpassion, singing at all the right times. At the sight of joy and excitement onthe audience' s faces, she smiled brilliantly, lighting up the hallAfter the performers bowed and moved offstage, Kirstie, still inexcitement, began to search for her family in the crowd. Then in thecrowd, Kirstie saw her mother wink at her and her stepfather give her a-up. Finally, she found Henry and tapped hirshoulder. Kindly, she smiled at him and said, " Thanks for, youknow.""No problem, "Henry replied with his smile. Kirstie thoughtto herself that her mom was right about kindness and maybe it wasn't sobad to have a new person in her corner of the world after all【点评】该范文围绕原文内容进行了非常合理的续写,紧扣语境,逻辑紧密,详略得当。第一段紧扣所给开头语中的提示信息,讲述了亨利在柯斯迪遇到窘况时及时利用自己的打结技巧帮助了她,并利用笑话转移观众的注意力,从而使柯斯迪全心投入到演出中;第二段则紧承第一段内容,讲述了柯斯迪成功演出后真诚地向亨利道谢,并接纳亨利成为自己的家人。以上内容既合理地对故事情节进行了延续,尤其是亨利懂得如何打结并在柯斯迪遇到困难时伸出援助之手,又把柯斯迪妈妈所说的做善良的事融入故事中,柯斯迪深受感动之余,也打开了心结,从此接纳这个重组的新家庭,续写将整个故事带入到一个十分感人的情境中。范文中不乏较为高级的表达,如 distract one,'s attention, thanks to one' s greathelp, with delight and passion, at the sight of, light up等高级短语以及现在分词短语作状语、 which引导的非限制性定语从句、"it+be+d+todo.."等句式,使得文章语言表达丰富优美

29.【答案】(除标明外,每空2分)(1)无水乙醇(有机溶剂)(1分)宽度或颜色深浅(1分)(2)先增大再减小(3)CO2的吸收速率或O2的释放速率(1分)不同土壤湿度条件下该植物呼吸速率的大小(4)15%~20%的土壤湿度下水分不足,叶绿素含量低,使净光合作用速率小,利用CO2的量少,从而导致胞间CO2浓度高,同时水分不足也使气孔开放度下降(合理即可)【关键能力】理解能力、实验分析能力、获取信息的能力【解题思路】(1)绿叶中色素提取实验的原理是色素易溶于有机溶剂(如无水乙醇)中。用纸层析法对从叶绿体中提取到的色素进行分离,滤纸条上色素带的宽度和颜色深浅能够反映色素的含量(拓展:色素的扩散速率与其溶解度有关,扩散速率越大说明其溶解度越大)。(2)从实验结果来看,在一定的范围内,随着土壤湿度的下降,该植物的净光合作用速率先增大再减小。(3)净光合速率可以用二氧化碳的吸收速率、氧气的释放速率、有机物的积累速率表示。植物的真正光合速率=净光合速率+呼吸速率,因为活的细胞时刻进行着呼吸作用,所以真正光合速率不能直接测得,可以通过测得一定条件下的净光合速率和呼吸速率来计算得出真正光合速率。(4)15%~20%的土壤湿度情况下,水分不足,叶绿素含量低,使净光合作用速率小,二氧化碳利用量少,从而导致CO2在胞间积累变多,同时水分不足也使气孔开放度下降。
