说明文语言的准确性
1、答：“不能删去。因为“适当”起限制作用，意思是一定的程度，表明有雾时，户外活动既不要全部停止，也不能不加限制，删掉后成了完全停止，与实际不符。“适当”体现了语言的准确性、科学性。
2、答：“适当”起限制作用。意思是一定的程度，表明有雾时，户外活动既不要全部停止，也不能不加一限制。体现了语言的准确性、科学性。
第一种题型
（1）“几近”是几乎接近的意思，说明毒蛇、飞虫差不多被吃光，但没有绝迹，这体现了说明语言的准确性。
（2）“可能”表示估计、推测，说明了鹭鸟数量减少的原因，但不是绝对肯定，这体现了说明语言的准确性。
3、“在当时”在时间上进行了限定，只说明了赵州桥的的桥拱在当时是最长的，但现在不是，这体现了语言的准确性。
第二种题型：
（1）1不能；2因为“可能”是估计、推测的意思，“最早”在时间上加以限制，它们是对旅人桥的最早出现的情况进行推测，但并不是绝对的，若删去，就肯定旅人桥是第一个出现的，不符合实际，“可能”和“最早”，体现了说明语言的准确性。
（2）1不能；2因为“独立”说明了不依靠其他拱圈也能自立，表明就算其中一道坏了，其他各道不致受到影响，若删去，就表明如果一道坏了，必然会影响其他各道，不符合实际，“独立”体现了说明语言的准确性。
3、（1）不能；（2）因为“最主要”是关系最大，起决定作用的意思，它表明水是征服沙漠的根本武器，但还有其他方面的手段或方法，若删去，就变成水是征服沙漠唯一的方法，不符合实际，“最主要” 体现了说明语言的准确性。
第四种题型：
3、（1）不能。（2）因为“往往”是大多数的意思，说明了天上的薄云大多预示着天气晴朗，但也不排除特殊情况。换成“总是”表明天上出现薄云一定表示天气晴朗，与客观事实不符合，“往往”一词体现了说明文语言的准确性。
平实与生动语言
试题演示A（1）特点：细微而难以看见、捉摸；平实说明：尘埃非常细小，小得让人难以捉摸。
（2）第一句：准确简明（简洁）,第二、三句：形象生动。（运用比喻、拟人）
B【答案】（1）从表达方式看：第③段运用了描写、议论和抒情的表达方式，既使说明显得形象鲜明，又增加文章的感染力。前者如“有的横在宽阔的草坪上，犹如在海中飘荡”，后者如“简直是一个天然的渔船文化实物展览馆。展品之丰富，设计之巧妙，令人称绝”。（2）从表现手法或修辞手法运用的角度分析：文章第③段运用了写实和想象结合、动静结合、比喻和拟人化的写法，修辞上还运用了排比、引用的手法，既使说明显得形象鲜明，又引发读者的丰富联想，充满了情趣和诗情画意。如“有的横在宽阔的草坪上，犹如在海中飘荡；有的停靠在观光码头，正归航休憩；有的搁散在沙滩中，似等待涨潮时再度起航??”
C【答案】文章末段多用整齐的短句，如“持鳌举酒，边剥边吃，淘醉之时，舔指回味，其乐无穷”，还运用了口语，如“真是做神仙也不过如此了”，使语言形象生动，幽默风趣，增添了文章的趣味性。
九年级英语作文含句子分析【四】
如何分析说明文中划线句子的作用
一、画线句子指向的知识点
1.划线句子是一段文字的中心句——出题者要考核的知识点是中心句的作用；
2.划线句子是过渡句——出题者要考核的知识点是过渡句的结构作用；
3.画线句子是一种或几种说明方法的运用部分——考核的知识点是说明方法的判定及其在说明过程中的作用；
4.划线句子是全文的说明目的——出题者要考核的知识点是说明文的目的，及这个句子的结构作用。
二、分析不同类型划线句子作用的答题方法
（一）划线句子是一段文字的中心句
1.指出其在内容表达上的作用、效果；
2.指出其在结构上的作用。
例如：分析下面语段中划线句子的作用
抵御沙丘进攻的方法是植树种草。我国沙荒地区，有一部分沙丘已经长了草皮和灌木，不再转移阵地了。这种固定的沙丘，只要能妥善保护草皮和灌木，防止过度砍伐和任意放牧，就可以固定下来。根据近年治沙的，陕北榆林、内蒙古磴口、甘肃民勤地区的流动沙丘，表面干沙层的厚度一般不超过10厘米。10 厘米以下，水分含量逐渐增大，到40厘米的深处，水分含量达到2%以上，这就是湿沙层了。湿沙层的水分足够供应固定沙丘的植物的需要。所以在流动沙丘上植树种草，是可以成活的。林木和草类成长以后，沙丘就可以固定下来了。
1.对应的答案是：概括说明植树种草是抵御沙丘进攻的方法，语言简洁明快；
2.对应的答案是：总领全段。
将二者合起来，就是划线的中心句的作用（答案分为在内容表达和结构两个方面的作用）：概括说明植树种草是抵御沙丘进攻的方法，语言简洁明快；在结构上总领全段。
（二）划线句子是一个过渡句
1.指出这个句子的结构作用是承上，还是启下，或者是承上启下
2.对文章的整体结构有何好处；
3.指出：承上的——承接上文的什么内容；启下的——引出下文什么内容；承上启下的——上文承接什么内容，引出下文什么内容。
4.难点突破
（1）如何判定一个句子具有承上的结构作用
这个句子只要具备以下特征中的一个特征，就说明它具有承上功能：
A.句子中的词或短语对上文的表象内容具有概括作用。例如，刚才，我说明了使用手机的方法。其中“手机的使用方法”这个短语就对上文的表象内容进行了概括，所以这句话就具有承上功能。
B.过渡句中有某个词或短语，解释了上文的本质内容。例如海市蜃楼不是一种神仙鬼怪降临人世，而是光的一种折射成像现象。如果前一段描述的是海市蜃楼的现象，这句话中“是光的一种折射成像现象”就揭示了上文的本质内容，因而这句话也具有承上功能。
C.涉及到上文说明的内容。例如上文讲了一棵树，这个句子中提到相关的树叶、树根等，就说明这句话具有承上作用
D.和上文构成明显的逻辑关系。例如句子开头是“因此”、或者“那么”、或者“然而”，那么这个过渡句显然和上文有或因果、或假设、或转折逻辑联系；还有的句子开头是“其次”、“第二”等，明显前文有“首先”、“第一”等词，构成主次、或顺次关系，因而也具有承上功能。
（2）如何判定过渡句具有启下作用
承上的几种类型中词或短语与上文的关系转为对下文的关系，则是启下。
（3）如何判定过渡句具有承上启下的作用
过渡句中有的词或短语概括总结、或联系上文的内容，还有的词或短语概括、联系下文的内容，则这个过渡句就有承上启下的作用。
（4）如何判定过渡句的存在，对文章结构的好处
无论是承上、还是启下，抑或是承上启下，带来的好处都是使文章的结构严谨。
例如： 为什么我国的石拱桥会有这样光辉的成就呢？首先，在于我国劳动人民的勤劳和智慧。他们制作石料的工艺极其精巧，能把石料切成整块大石碑，又能把石块雕刻成各中形象。在建筑技术上有很多创造，在起重吊装方面更有意想不到的办法。如福建漳州的江东桥，修建于八百年前，有的石梁一块就有二百来吨重，究竟是怎样安装上去的，至今还不完全知道。其次，我国石拱桥的设计有优良传统，建成的桥，用料省，结构巧，强度高。再其次，我国富有建筑用的
各种石料，便于就地取材，这也为修造石桥提供了有利条件。
文中这个划线句子就是针对过渡句的结构作用出的试题。“这样辉煌的成就”概括了上文赵州桥的历史、结构、造型特点，具有承上作用，“为什么”这个疑问代词，概括了这一段的主要内容，所以具有启下的作用。
综上所述，在这个段落中，划线句子的作用就是：承上启下，上承接我国石拱桥取得的辉煌成就，下引出取得成就的原因，使文章架构严谨。
（三）划线句子考核的是说明方法及其作用
1.要指出句子运用的说明方法有哪些（不要遗漏）？
2.要指出运用这种说明方法说明的核心内容是什么？
3.要指出运用这种说明方法带来怎样的效果？
样，就使海水的密度大于人体的密度，无怪乎人一到海里就自然漂起来，沉不下去。
1.运用的说明方法有：引资料、分类别、列数字；
2.主要说明了：死海的咸度高、浮力大。 3.效果
（1）引资料：突出材料的科学性、准确性，增强说服力； （2）分类别：将死海中的矿物质分成若干种类一一说明，条理清晰，层次井然；
（3）列数字：准确具体。
整体答案就是：这句话运用引资料、分类别、列数字三种说明方法，说明了死海的咸度高、浮力大这一突出特点，说明过程引用材料、数据科学、准确、具体，增强了说服力，同时把复杂的内容说明得条理清晰，层次井然。
（四）划线句子就是点名文章写作意图（写作目的）的句子
1.指出其结构作用：总结全文；
吸烟，严重损害着自己的生
命，威胁着他人的健康。我们要切实行动起来，高高扬起禁烟的旗帜！ 例如：人们种植香烟，浪费了大量的土地资源；社会消费香烟，浪费了大量的资金。
划线句子的作用是：总结全文，点明文章的写作目的（写作意图），倡导大家积极参与禁烟行动。
