卜细胞 少，萝 ；D 成熟区，作用根吸 和 初中生物易错题归纳 一、吸水与失水 1、植物在生命活动过程中必须不断地从外界环境吸收水和无机盐，根是吸收水和无机盐的主要器官。下图分别表示根尖的结构和植物细胞吸水、失水状态的示意图，请据 图回答问题： （1）根是陆生植物吸水的主要器官，根吸收水和无机盐的主要部位是甲图中的【 D】成熟区。 （2）细胞中控制内外物质进出的结构是细胞膜。 （3）根吸收水分时，水分主要进入细胞内的结构是液泡。 （4）用糖拌西红柿，不久会有许多汁液流出，其原因是外界溶液的浓度大于（大于或小于）西红柿细胞的细胞液浓度，造成细胞失水，其状态如乙图所示。 （5）根细胞吸水的根本原因是土壤溶液浓度小于根细胞液浓度。（选填“大于”或“小于”） （6）根据以上实验结论，我们可以解释农业生产中一次施肥过多，会造成水稻的“烧苗”现象，这是因为（ A ） A.土壤溶液浓度过大，根细胞失水 B.土壤温度太高 C.水分太多，根无法呼吸 D.土壤缺乏足够的营养 2.学生兴趣小组为了研究外界溶液浓度对植物细胞吸水和失水的影响，设计了如下探究实验：取两个大小相同的萝卜，各从顶端向下挖一个大小一样的洞。在A萝卜洞内装 上浓盐水，在B萝卜洞内装上等量的清水，过一段时间后，观察萝卜洞内液面升降的变化（如图一）。 （1）该探究实验的变量是：外界溶液浓度。 （2）过了12小时候后观察发现：A萝卜洞里的水变多，萝卜变软；B萝卜洞里的水则变图一 变化。 卜变硬，那么，此时B萝图二发生了如图二中①（填序号）所示的 （3）得出结论：当外界溶液的浓度▲小于（大于或小于）萝卜细胞液浓度时，细胞吸水；反之则细胞失水。 相关知识：1.在细胞的结构中，保护细胞内部结构，维持细胞形态的是细胞壁；控制物质进出 的是细胞膜；与吸水和失水有关的是液泡，与光合作用有关的是叶绿体，与呼吸作用有关 的是线粒体。 2.在根尖的结构中，如图甲所示，A根冠，作用保护；B 分生区，作用细胞分裂；C 伸长区，作用根尖伸长失水 的主要器官。 二、泌尿系统 人体在新陈代谢中产生的废物主要通过泌尿系统排出体外，请根据泌尿系统结构示意图和下表中的相关信息回答： （1）人体泌尿系统的主要功能是形成和排出尿液，图②所示结构称之为输尿管，其主要作用是输送尿液。 （3）图③所示结构的功能是暂时贮存尿液。图中【①】肾脏是形成尿液的器官。 （2）根据表格中的数据可以判断 C 液为尿液，它可以暂时贮存在【③】膀胱中，一旦有尿意，应及时排出。 （3）若某人胰岛素分泌不足，则从【④】排出的液体中可检测出葡萄糖。可用胰岛素制剂来治疗。 （4）如果某人的尿液中出现了大量的蛋白质和血细胞，他有可能出现病变的是肾小管； （5）右图是尿液形成的示意图，图中①肾小囊中的液体是原尿；血浆中有大分子蛋白质，而原尿中没有，这是因为肾小球的滤过作用。 原尿中有葡萄糖而尿液没有，这是因为② 肾小管的重吸收。若化验出某人尿液中有葡萄糖，医生推断该病人的发病部位最可能是。三、无性生殖和有性生殖 1. 甲乙丙丁 （1）水蜜桃味美汁多，生产上常采用的繁殖方法是图【乙】芽接。 （2）图丙所示的生殖方式属于有性生殖，其种子中能萌发成幼苗的结构由受精卵发育而来。 （3）若要在短时间内生产出大批康乃馨等花卉幼苗，生产上常利用的技术是图【丁】组织培养。 2. 成分 A 液(克／100 毫升) B 液(克／100 毫升) C 液(克／100 毫升) 水90 98 96 蛋白质8.00 O.03 0.00 葡萄糖0.10 0.10 O.00 无机盐O.72 0.72 1.10 尿素0.03 0.03 1.80

高考英语易错题汇编（思维定势） 1. They ______ on the program for almost one week before I joined them, and now we _____on it as no good results have come out so far. A. had been working; are still working B. had worked; were still working C. have been working; have worked D. have worked; are still working 此题的时间参照点是before I joined them,，所以第一个空应该用过去完成进行时，第二个空根据时间now用现在进行时。 2. It would be a good idea to use a plastic bottle, ___cut off, as a container to grow young plants in. A. of which the top B. the top is C. the top of which D. with its top 此题是独立主格结构，如果题干改为 ____is cut off,答案则为A或C 3. ______ is it _____ has made Peter _____ he is today? A. What; that; that B. That; that; what C. What; what; that D. What; that; what 用还原法则为 It is what that has made Peter what he is today k可知是强调句式。 4. Before he went abroad，he spent as much time as he _____ English. A. could learning B. learned C. to learn D. could learn spend time (in) doing sth 如果改为he did what he ______, 则答案为could to learn. 5. The person we talked about ____ our school last week． A．visiting B．will visit C．visited D．has visited 此题中包含一个定语从句，the person既作先行词，又作句子的主语，要填入的应该是句子的谓语，根据后面的时间状语为last week，应选过去时。句中包含的定语从句we talked about中about虽为介词，但不影响主句的谓语，故应选C。 观察下面三个句子： □The pers on we spoke to ____ no answer at first． A．making B．makes C．make D．made 此题中也包含一个定语从句we spoke to，the person既作先行词，又作句子的主语，要填入的应该是句子的谓语，根据句子的需要，应选过去时。本题中的to为陷阱，实际上它属于定语从句中，而不影响主句的谓语动词。故D正确。 □The person we referred to（提及）____ us a report tomorrow． A．giving B．will give C．gave D．give 同上题一样，句中包含定语从句we referred to，所缺成份为句子的谓语，又根据句中的tomorrow，故用将来时。选B。 □The days we have been looking forward to ____ soon． A．coming B．will come C．came D．have come 同理，此句中的定语从句包含短语look forward to，虽然to 为介词，但并不影响主句的谓语动词，只是一个陷阱而矣。又根据句中的soon，应用将来时，故选B。 6. Not far from the club there was a garden, ____ owner seated in it playing bridge with his children every afternoon. A. whose B. its C. which D. that 答案为B。此题关键是理解seated这个单词，它是过去分词，而不是作谓语的过去式。它不能在句中谓语。所以后面句子不是一个非限制性定语从句，而是一个独立主格结构，故选代词its。 7. You should treat him (in) the way ____ suits him most. A. that B. in which C. / D. why 此题中先行词the way 后面的定语从句中充当主语。故只能选A。如果先行词the way有从句中充当
