利用一定方法使细胞群体处于细胞周期的同一阶段，称为细胞周期同步化。以下是能够实现动物细胞周期同步化的三种方法。回答下列问题：

（1）DNA合成阻断法：在细胞处于对数生长期的培养液中添加适量的DNA合成可逆抑制剂，处于_____________期的细胞不受影响而继续细胞周期的运转，最终细胞会停滞在细胞周期的___________________期，以达到细胞周期同步化的目的。（2）秋水仙素阻断法：在细胞处于对数生长期的培养液中添加适量的秋水仙素，秋水仙素能够抑制_________________，使细胞周期被阻断，即可实现细胞周期同步化。经秋水仙素处理的细胞______________（填“会”或“不会”）被阻断在间期。

（3）血清饥饿法：培养液中缺少血清可以使细胞周期停滞在间期，以实现细胞周期同步化，分裂间期的特点是________________（答出1点即可）。

答案（1）分裂期分裂间

（2）着丝点分裂、纺锤体的形成，阻止染色体移向两极 不会

（3）相关蛋白的合成、染色体进行复制、细胞体积略有增大

解析（1）DNA复制发生在细胞分裂间期；

DNA合成被阻断后，分裂期不受影响，分裂间期受影响。（2）秋水仙素通过抑制纺锤丝的形成来使染色体数目加倍，而纺锤丝形成于有丝分裂前期；

经秋水仙素处理的细胞不会被阻断在间期。（3）分裂间期的特点是相关蛋白的合成、染色体进行复制、细胞体积略有增大。

30．（9分）

干旱可促进植物体内脱落酸（ABA）的合成，取正常水分条件下生长的某种植物的野生型和ABA缺失突变幼苗，进行适度干旱处理，测定一定时间内茎叶和根的生长量，结果如图所示：

回答下列问题：

（1）综合分析上图可知，干旱条件下，ABA对野生型幼苗的作用是_______。

（2）若给干旱处理的突变体幼苗施加适量的ABA，推测植物叶片的蒸腾速率会______，以对环境的变化作出反应。

（3）ABA有“逆境激素”之称，其在植物体中的主要合成部位有______（答出两点即可）。

（4）根系是植物吸收水分的主要器官。根细胞内水分的主要作用有________（答出两点即可）。

答案（1）抑制茎叶生长，促进根生长（2）增大（3）根冠、萎蔫的叶片

（4）作为化学反应的溶剂维持细胞渗透压提供反应的原料

解析（1）由图可以直接看出，与突变型（不能合成ABA）相比，野生型（能合成ABA）植株茎叶生长受到抑制，根的生长被促进。（2）施加ABA后，根生长加快，从土壤吸收水分增多，植物叶片的蒸腾速率会加快，以对环境的变化作出反应。（3）ABA主要在植物体的根冠、萎蔫的叶片中合成。（4）根细胞内水分的主要作用有作为化学反应的溶剂、维持细胞渗透压、提供反应的原料、组成细胞的结构。

31．（10分）

为研究胰岛素的生理作用，某同学将禁食一段时间的实验小鼠随机分为A、B、C、D四组，A组腹腔注射生理盐水，B、C、D三组均腹腔注射等量胰岛素溶液，一段时间后，B、C、D三组出现反应迟钝、嗜睡等症状，而A组未出现这些症状。回答下列问题：

（1）B、C、D三组出现上述症状的原因是________。

（2）B、C、D三组出现上述症状后进行第二次注射，给B组腹腔注射生理盐水；

为尽快缓解上述症状给C组注射某种激素、给D组注射某种营养物质。那么C组注射的激素是__________，D组注射的营养物质是__________。

（3）第二次注射后，C、D两组的症状得到缓解，缓解的机理分别是__________________。

答案（1）体内血糖含量下降

（2）胰高血糖素 葡萄糖

（3）C组：胰高血糖素促进非糖物质转化为糖类、促进肝糖原的分解；

D组：注射葡萄糖，使体内血糖升高。

解析（1）胰岛素是降血糖激素。（2）（3）胰高血糖素促进非糖物质转化为糖类、促进肝糖原的分解；

注射葡萄糖，使体内血糖升高。

32．（12分）

已知某种昆虫的有眼（A）与无眼（a）、正常刚毛（B）与小刚毛（b）、正常翅（E）与斑翅（e）这三对相对性状各受一对等位基因控制。现有三个纯合品系：①aaBBEE、②AAbbEE和③AABBee。假定不发生染色体变异和染色体交换，回答下列问题：

（1）若A/a、B/b、E/e这三对等位基因都位于常染色体上，请以上述品系为材料，设计实验来确定这三对等位基因是否分别位于三对染色体上。（要求：写出实验思路、预期实验结果、得出结论）

（2）假设A/a、B/b这两对等位基因都位X染色体上，请以上述品系为材料，设计实验对这一假设进行验证。（要求：写出实验思路、预期实验结果、得出结论）

答案（1）实验思路：让①和②杂交、①和③杂交、③和②杂交。得到的子一代自交

如果子二代中出现8种表现型就说明三对等位基因分别位于三对染色体上。

预期实验结果：子二代中有8种表现型（子二代中的表现型不是8种）

得出结论：三对等位基因分别位于三对染色体上（三对等位基因不是位于三对染色体上）

（2）实验思路，预期实验结果：：让①和②杂交，①为母本，②为父本。产生的所有雄性均表现为无眼刚毛正常翅膀。②为母本，①为父本。产生的所有雄性均表现为有眼小刚毛正常翅膀。

得出结论：A/a、B/b这两对等位基因都为为X染色体上

（5）该实验操作过程中应注意的事项是_________________（答出两点即可）。

答案（1）晾干 物质W受热、受潮易分解

（2）使物质W完全溶于加溶剂

（3）吸收有机溶剂和水分

（4）其沸点相对较低，温度过高会导致物质W分解

（5）新鲜的植物含有大量的水分，在干燥时注意控制干燥时间，时间过长会导致物质W分解

解析属于对识记层次的考查，解析见答案。

38．[生物——选修3：现代生物科技专题]（15分）

编码蛋白甲的DNA序列（序列甲）由A、B、C、D、E五个片段组成，编码蛋白乙和丙的序列由序列甲的部分片段组成，如图1所示。

回答下列问题：

（1）先要通过基因工程的方法获得蛋白乙，若在启动子的下游直接接上编码蛋白乙的DNA序列（TTCGCTTCT……CAGGAAGGA），则所构建的表达载体转入宿主细胞后不能翻译出蛋白乙，原因是______________.

（2）某同学在用PCR技术获取DNA片段B或D的过程中，在PCR反应体系中加入了DNA聚合酶、引物等，还加入了序列甲作为_____________________，加入了________________作为合成DNA的原料。

（3）现通过基因工程方法获得了甲、乙、丙三种蛋白，要鉴定这三种蛋白是否具有刺激T淋巴细胞增殖的作用，某同学做了如下实验：将一定量的含T淋巴细胞的培养液平均分成四组，其中三组分别加入等量的蛋白甲、乙、丙，另一组作为对照，培养并定期检测T淋巴细胞浓度，结果如图2。

①由图2可知，当细胞浓度达到a时，添加蛋白乙的培养液中T淋巴细胞浓度不再增加，此时若要使T淋巴细胞继续增殖，可采用的方法是__________________。细胞培养过程中，培养箱中通常要维持一定的C2O浓度，C2O的作用是__________________。

②仅根据图、图2可知，上述甲、乙、丙三种蛋白中，若缺少______________（填“A”“B”“C”“D”或“E”）片段所编码的肽段，则会降低其刺激T淋巴细胞增殖的效果。

答案（1）因为在启动子的下游接上的编码蛋白乙的DNA序列，不能启动

（2）模板DNA 四种脱氧核苷酸

（3）细胞培养（传代培养）维持培养箱中的pH

（4）C

B．绿色化学要求从源头上消除或减少生产活动对环境的污染

C．燃煤中加入CaO可以减少酸雨的形成及温室气体的排放

D．天然气和液化石油气是我国目前推广使用的清洁燃料

B．淀粉和纤维素互为同分异构体

C．环己烷与苯可用酸性KMnO4溶液鉴别

D．水可以用来分离溴苯和苯的混合物

B.淀粉和纤维素的聚合度不同，造成它们的分子式不同，所以不是同分异构体，故B错误；

C.环己烷与苯都不与酸性KMnO4溶液反应，所以不能用该方法鉴别环己烷与苯，故C错误；

D.溴苯与苯互溶，不能用水分离溴苯和苯的混合物，故D错误；

答案为A。

这部分内容主要考察的是逻辑主语的知识点：

动词在一个整句中充当某一个成分——谓语动词、主语、谓语的宾语、修饰成分(定语、状语和补语)时，表达一个动作的概念，描述一个具有一定动机和目的并指向一定客体的运动系统。动作系统不是孤立的，即不存在没有源头的动作，对于每个动作，都有对应的主体（发出者）。

动词代表的动作系统中的主体，即施动者，称作这个动词的逻辑主语。同样地，动词代表动作系统中的客体，即受动者，称作这个动词的逻辑宾语。语法主语即在一个句子，在语法上作主语部分。逻辑主语不同于语法主语，但两者并不对立。

逻辑主语代表着动作系统的发出者，语法主语则决定了谓语动词的时态语态。语法主语在语法结构上和主语构成主谓结构，但在逻辑上它们可以是谓语动词动作系统的受动者，也可以是谓语动词动作系统的施动者。当语法主语和谓语动词是主动关系时，语法主语即是逻辑主语；当语法主语和谓语动词是被动关系时，语法主语是谓语动词的逻辑宾语。

观察下列句子：

Our child planted a tree.(我们的孩子植了棵树。)

A tree was planted by our child.(一棵树被我们孩子植了。)

两个表达中，植树这个动作都是由“our child”发出的，故谓语部分动词的逻辑主语都是“our child”。但他们的语法主语不同：第一句是“Our child”，而第二句是“A tree”。

在表述中，有时强调动作本身，常常把逻辑主语变位作其他成分（介词宾语等）或者省略，构成“祈使句”、“被动句”等结构。

　根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。(共5小题，每小题3分，共15分)

　How to Improve Vocabulary Fast

　Your vocabulary refers to the words in a language you are familiar with. We should learn some ways to expand it.

　Read every day. 36 Choose reading material that is slightly above your level and keep a dictionary with you to look up words you do not know.

　37 If you do not meet with an unfamiliar word in your daily reading, use your dictionary to search for one.

　Learn the correct definition and pronunciation for each new word. Pronunciation is as important as definition because in order to add a word to your active vocabulary, you must be able to use it in speech.

　Elaborate(阐释)on the meaning of the word. Use imagery and personal relevance. If you have just learned the word ?stubborn?, think about the neighbor who will not lend you his car. 38

　Dear Manager,

　My name is Li Hua. I stayed at your hotel, Forest Hotel, during my visit to the UK from Jan 28 to 30 with my parents. However, the service in your hotel left much to be desired. I?m writing this email to express my opinion.

First, we found our suitcases broken after they were carried to our room by one of your porters. Second, water was leaking out of the toilet in the bathroom. Third, the noise from the bar downstairs went on so late into the night each night that we couldn?t get good rest.

　For the above reasons, I have to say that the service in your hotel is of poor quality. Therefore, I would like to receive a written apology from you. Meanwhile, I hope you can improve your service in the future so that none of the above happens again.

　Yours sincerely,

　LI HUA

　My Pencil-box

　I have a pencil-box. It is nice and big. It has many colours. There are two blocks on my pencil-box. One is yellow, the other is orange. In my pencil-box, there are pens, pencils, a ruler and an eraser. I like my pencil-box very much and my pencil-box looks like my best friend.

I work with Volunteers for Wildlife, a rescue and education organization at Bailey Arboretum in LocustValley. Trying to help injured, displaced or sick creatures can be heartbreaking; survival is never certain. However, when it works, it is simply beautiful.

我在“野生动物志愿者”组织工作，这是蝗虫谷贝利植物园的一个援救教育组织，帮助受伤、流离失所或生病的动物。这样的工作可能会令人心碎；因为无法确定动物是否能活下来。然而，当救援起作用时，这种感觉真的很棒！

I got a rescue call from a woman in Muttontown. She had found a young owl on the ground. When I arrived, I saw a 2-to 3-week-old owl. It had already been placed in a carrier for safety.

我接到马特顿镇一位女士的求救电话，她在地上发现了一只猫头鹰幼鸟。当我到达时，我看见了一只两三周大的猫头鹰。为了安全起见，它已经被放在一辆大货车上。

I examined the chick and it seemed fine. If I could locate the nest, I might have been able to put it back, but no luck. My next work was to construct a nest and anchor it in a tree.

我检查了这只幼鸟，看起来还不错。如果我能找到鸟巢，我也许能把它放回去，但没那么幸运。接下来的工作就是建造一只鸟巢，并固定在一棵树上。

The homeowner was very helpful. A wire basket was found. I put some pine branches into the basket to make this nest safe and comfortable. I placed the chick in the nest, and it quickly calmed down.

房主非常乐于助人，给我找来了一只铁丝篮。为了让鸟巢安全舒适，我把一些松枝放进铁丝篮里，然后我把小猫头鹰放进鸟巢里，它很快安静了下来。

Now all that was needed were the parents, but they were absent. I gave the homeowner a recording of the hunger screams of owl chicks. These advertise the presence of chicks to adults; they might also encourage our chick to start calling as well. I gave the owner as much information as possible and headed home to see what news the night might bring.

现在最需要的是这只小猫头鹰的父母，但它们不在。我给了房主一份小猫头鹰饥饿尖叫声的录音。这些录音会让猫头鹰父母知道小猫头鹰的存在，也会鼓励小猫头鹰学着尖叫。我把尽可能多的消息告诉了房主，然后回家，看看晚上会有什么情况。

A nervous night to be sure, but sometimes the spirits of nature smile on us all! The homeowner called to say that the parents had responded to the recordings. I drove over and saw the chick in the nest looking healthy and active. And it was accompanied in the nest by the greatest sight of all — LUNCH！The parents had done their duty and would probably continue to do so.

这的确是一个紧张的夜晚，但有时大自然的神灵会眷顾我们！房主打电话说小猫头鹰的父母已经对这些录音做出了回应。我开车过去，鸟巢里的小猫头鹰看起来健康又活泼。鸟巢里出现了最令人感动的一幕——小猫头鹰的身边全是午餐！它的父母已经在尽职尽责，而且很可能会继续这样做。
