Everyone knows that death is natural, but do you have any idea of the process of dying? Modern scientists divide the process of dying into two stages — clinical or temporary death and biological death. Clinical death occurs when the vital organs, such as the heart or lungs, have stopped functioning, but have not suffered permanent damage. The organism can still be saved. Biological death occurs when changes in the organism lead to the “breaking up” of vital ce lls and tissues. Death is then unchangeable and final.
Scientists have been seeking a way to prolong the period of clinical death so that the organism can remain alive before biological death occurs. The best method developed so far involves cooling the organism, combined with narcotic (麻醉) sleep. By slowing down the body’s metabolism (新陈代谢), cooling delays the processes leading to biological death.
To show how this works, scientists performed an experiment on a six-year-old female monkey called Keta. The scientist put Keta to sleep with a narcotic. Then they surrounded her body with ice-bags and began checking her body temperature. When it had dropped to 28 degrees the scientists began taking blood out from an artery (动脉). The monkey’s blood pressure decrea sed and an hour later both the heart and breathing stopped: clinical death set in. For twenty minutes Keta remained in this state. Her temperature dropped to 22 degrees. At this point the scientists pumped blood into an artery in the direction of the heart and started artificial breathing. After two minutes Keta’s heart became active once more. After fifteen minutes, spontaneous (自发的) breathing began, and after four hours Keta opened her eyes and lifted her head. After six hours, when the scientists tried to give her a penicillin (青霉素) injection, Keta seized the syringe (注射器)and ran with it around the room. Her behavior differed little from that of a healthy animal.
1.For a person who suffers from the clinical death _________.
A. he is still very much alive
B. he cannot avoid final death
C. his most important organs are damaged forever
D. he still has the possibility of getting back to life
2.Scientists try to make the time of clinical death longer in order to _________.
A. cool the organism
B. delay the coming of biological death
C. slow down the body’s metabolism
D. bring vital cells and tissues back to active life
3.The text mainly talks about _________.
A. clinical death and biological death
B.an experiment on a monkey
C. the meaning of death
D. the process before death
4.From the underlined sentence in the last paragraph we can know that _________.
A. Keta was impolite
B. Keta was healthy
C. Keta was ill
D. Keta was crazy
【文章大意】本文主要叙述了为了延缓生理死亡的到来，科学家尽量延长临床死亡的时间。
1.D 【解析】细节理解题。由文章第一段内容“Clinical death occurs when the vital organs,
such as the heart or lungs, have stopped functioning, but have not suffered permanent damage. The organism can still be saved”可知，一个临床死亡的人还有可能活过来，故选D。
3.A 【解析】主旨大意题。文章第一段提出了人类死亡的两个阶段：临床死亡和生理死亡；第
二段提出科学家们想办法延长临床死亡；第三段通过用猴子做实验来验证延长临床死亡的方法，故本文主要论述了临床死亡和生理死亡，选A项。
4.B 【解析】推理判断题。结合文章最后一句“Her behavior differed little from that of
a healthy animal.”（她的行为无异于健康动物的行为），可推知划线部分句子说明Keta
是健康的，故选B项。

2．was awarded 考查动词的时态和语态。主语Zhangjiajie和动词award之间是被动关系，应用被动语态；根据该句中的时间状语“in 2004”可知，应用一般过去时。
3．Actually 考查词性转换。空处修饰整个句子，故用副词形式。
4．an 考查冠词。根据语境可知，该处泛指“一幅放大的盆栽风景画”，空后的enlarged的发音以元音音素开头，故用不定冠词an。
5．at 考查介词。这里指“吸引了国内外的大量游客”，at home and abroad为固定短语，意为“在国内外”，故用at。
6．has become 考查动词的时态。根据该句中的时间状语“Since it was ... 1980s”可知，空处表示过去的动作对现在产生的影响，故用现在完成时。
7．related 考查非谓语动词。be related to为固定搭配，此句中，动词relate和
名词industries之间存在逻辑上的动宾关系，故用过去分词短语作名词的后置定语。
8．its 考查代词。根据该句中的“magnificent natural scenery”可知，应用形容
词性物主代词its，指张家界的。
9．activities 考查名词复数。张家界景点的旅游活动有多种，故用复数形式。
10．what 考查宾语从句的连接词。分析该句结构可知，空处引导宾语从句，作介词by的宾语，且空处在从句中作主语，表示“……的事物”，故用what。

As a senior three student, I often imagine how I will be doing in the future. Talked about my dream job, I expect to be an English teacher for the following
reasons ：
First, I'm an energetic and outgoing boy with great patient. That's what a qualified teacher should had, in my opinion. Besides, I am crazy about the English language, I am doing quite well. Above all, teachers are generally respect. With two vacations each year, I may enjoy more relaxed time. As
an ambitious boy, I hope to take up a job which is beneficial for society. Being a good teacher may influence more students to shoulder his responsibilities and contribute to their country.
In a short, I'll work very hard to become a popular English teacher.
答案： As a senior three student, I often imagine how ①what
I will be doing in the future. Talked ②Talking
about my dream job, I expect to be an English teacher for the following reasons ： First, I'm an energetic and outgoing boy with great patient ③patience

难项分析：
第二处：Talked→Talking 考查非谓语动词。I 和talk about 为逻辑上的主谓关系，且talk about 和expect to be 所表示的动作同时发生，故用现在分词作状语。
第五处：I 前加and 考查连词。分析句子结构并结合语境可知，前后两句话为并列关系，故应用连词and 。
第八处：for→to 考查固定搭配。be beneficial to 表示“对……有益”。

专题复习16--甲烷乙烯苯知识点总结 核心知识图 1．烃的分类、通式和主要化学性质 氧化：燃烧 饱和烃：烷烃C n H2n+2(n≥1) 甲烷取代结构：链状、碳碳单键裂解 链烃氧化：燃烧、使KMnO4(H+)褪色 (脂肪烃) 烯烃C n H2n(n≥2) 乙烯加成：H2、X2、HX 、H2O等 结构：链状、碳碳双键加聚 氧化：燃烧、使KMnO4(H+)褪色 炔烃C n H2n-2(n≥2) 乙炔加成 不饱和烃结构：链状、碳碳叁键加聚 氧化：燃烧、使KMnO4(H+)褪色 烃二烯烃C n H2n-2 (n≥3) 1，3—丁二烯加成：1，2加成、1，4加成 结构：链状、两个碳碳双键加聚 饱和环烃：环烷烃C n H2n (n≥3) 结构：环状、碳碳单键氧化：燃烧、不能使KMnO4(H+)褪色，不能因反应使反应使溴水褪色 苯加成 环烃取代：卤代、硝化、磺化 苯及其同系物C n H2n-6 (n≥6) 结构：环状、大 键 不饱和环烃：芳香烃氧化：燃烧、使KMnO4(H+)褪色 稠环芳烃：萘、蒽甲苯取代 加成 甲烷的化学性质 通常情况较稳定，与强酸、强碱、KMnO4等均不反应。 (1)氧化反应甲烷燃烧的热化学方程式为： (2)取代反应 ①定义：有机物分子里的某些被其他 所替代的反应。 ②甲烷与Cl2反应 乙烯烯烃知识点总结 一、乙烯的组成和结构 乙烯分子的结构简式：CH2〓 CH2 乙烯分子的结构： 键角约120°，分子中所有原子在同一平面，属平面四边形分子。 二、乙烯的制法 工业上所用的大量乙烯主要是从石油炼制厂和石油化工厂所生产的气体中分离出来的。
实验室制备原理及装置 三、乙烯的性质 1.物理性质：无色、稍有气味、难溶于水、密度小于空气的密度。 2.化学性质 （1）氧化反应 a.燃烧 CH 2=CH 2+3O 2??→?点燃 2CO 2+2H 2O （火焰明亮，并伴有黑烟） b.使酸性KMnO 4溶液褪色 （2）加成反应：有机物分子中双键（或叁键）两端的碳原子与其他原子或原子团直接结合生成新的化合物的反应。 （溴的四氯化碳溶液的红棕色褪去） 乙烯除了与溴之外还可以与H 2O 、H 2、卤化氢、Cl 2等在一定条件下发生加成反应，如工业制酒精的原理就是利用乙烯与H 2O 的加成反应而生成乙醇. 3）聚合反应 n CH 2==CH 2???→?催化剂［— CH 2—CH 2 ］— n （ 聚乙烯） 其中 CH 2=CH 2 为单体 —CH 2—CH 2— 为链节 n 为聚合度 四、乙烯的用途 作植物生长的调节剂，还可以作催熟剂；可用于制酒精、塑料、合成纤维、有机溶剂等， 五、烯烃 1.烯烃的概念：分子里含有碳碳双键的一类链烃 2.烯烃的通式：C n H 2n （n ≥2） 最简式：CH 2 可见，烯烃中碳和氢的质量分数别为85.7%和14.3%，恒定不变 环烷烃的通式与烯烃的通式相同，故通式为C n H 2n 的烃不一定是烯烃，如右图中其分子符合C n H 2n ，但不是烯烃而是环烷烃。 （环丁烷） 一般，我们所说的烯烃都是指分子中只含一个碳碳双键的不饱和烃，所以也叫单烯烃，也还有二烯烃：CH 2=CH － CH=CH 2 苯及其同系物知识点 苯 分子结构 分子式：C 6H 6 最简式：CH 结构式： 结构简式：或 比例模型： 球棍模型： 空间构型： 1、具有平面正六边形结构，所有原子共平面 2、键角都是120°。 3、不存在单双键交替排列，6个碳碳键完全相同，是一种介于单键和双键之间的独特的化学键。

高考七选五专题训练 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。 一 I started working at Pizza Hut in December 1989, when I was a freshman in high school. All new employees started by washing dishes and busing tables. If they proved their ability, they learned to make pizzas, cut and serve them on wooden paddles and take orders. 1 I couldn’t keep up, and piles of dishes formed on all sides of me. Every time the pile decreased, the call came back to help clear tables out front, and I returned with more dirty dishes. My shift (轮班) was supposed to end at 9 p.m., but when I asked to leave, the manager, Jeff, shook his head. “Not until the work is done,”he said. “You leave a clean station. 2 However, I worked until after 10 that night. I stayed on dish duty for weeks. My heart sank every time I arrived at work and saw my name written next to “dishes” on the position chart. I spent my shifts behind those steel sinks. I hated every minute I spent on dish duty. 3 One slow mid-week night, when I managed to catch up on dishes and clean out the sinks early, I asked Jeff when I could do something different. “Do you know why you’re still doing dishes?”he asked. “Because you keep complaining about it.” 4 But, he promised, if I continued to leave a clean station and not complain, next week he would put me on the “make table,” where pizzas were put together before being put into the oven. A few days later, when I reported for my after-school shift, I saw my name penciled not in the “dishes” box but in the “make table” box. 5 A. I was excited. B. Some write on a chalkboard. C. I was angry and thought about quitting. D. Nobody likes to work with a complainer, he said. E. And I wasn’t afraid to let everyone around me know it. F. On my first night, the dishes piled up after the dinner rush. G. The people who make a difference in your life come in all types.

2019高考英语阅读理解专题选编（12） 李仕才 A In 1959, when Jean Harper was in the third grade, her teacher gave the class an assignment to write a report on what they wanted to be when they grew up. Jean’s father was a crop dusting pilot in the little farming community in N orthern California where she was raised, and Jean was very interested in airplanes and flying. She poured her heart into her report and included all of her dreams. She wanted to be a crop dusting pilot, make parachute jumps(跳伞), and be an airline pilot. Her paper came back with an "F" on it. The teacher told her it was a "fairy tale" and that none of the occupations she listed were women’s jobs. Jean was devastated and humiliated. One day in her senior year of high school, her English teacher Mrs Dorothy Slaton gave the class an assignment. "If you had unlimited money, unlimited access to the finest schools, and unlimited talents and abilities, what would you do?" Jean felt a rush of her old enthusiasm, and with excitement she wrote down all her old dreams. The teacher leaned forward over her desk and said, "You do have unlimited abilities and talents. When you leave school, if you don’t go for your dreams, no one will do it for you. You can have what you want if you want it enough." The hurt and fear of years of discouragement went away because of what Mrs Slaton had said. Jean felt excited and a little scared. She stayed after class and went up to the teacher’s desk. Jean thanked Mrs Slaton and told her about her dream of becoming a pilot. Mrs Slaton half rose and slapped the desk top. "Then do it!" she said. So Jean did. It didn’t happen overnight. It took her 10 years of hard work. It wasn’t in Jean’s nature to stand up for herself when someone refused or humiliated her. Instead, she would quietly try to find another way. She became a private pilot and then flew planes as a co-pilot (副驾驶员). In 1978, she became one of the first three female pilot trainees ever accepted by United Airlines and one of the only 50 women airline pilots in the nation at that time. Some years later, Jean Harper became a Boeing 737 captain for United Airlines. 1.When Jean Harper was in the third grade, _________.

K ey w ords oxidative coupling of methane ethylene catalyst 现代工业三大能源:煤、石油、天然气中,天然气 占有十分重要的地位。CH 4是天然气中的主要成分,含量90%以上,CH 4好的化学稳定性使天然气的开发和加工大受限制,活化CH 4使之转化为化工原料已成为C 1化学研究领域[1]的重要课题。 CH 4的利用途径主要有直接选择氧化制合成气、部分氧化制甲醇和甲醛、氧化偶联(OC M )制C 2烃以及甲烷无氧芳构化。自K eller 和Bhasin [2]1982年首次研究OC M 以来,由于石油价格上涨和乙烯在石油化工工业上的重要性使该领域的研究不断深入,开发表征了一些高活性、高C 2选择性的催化剂体系并对O 2的活化及CH 4转化机理进行了广泛的研究[3],取 得了可喜的进展。 1催化剂 1.1 催化剂研究的方向 众所周知,从化学组分而言,催化剂的研制包括 主组分、助催化剂及载体的选择。与此同时,催化剂的物理化学及物理参数(如晶态、表面状态、孔隙结构及表面积等)对其性能也有不容低估的影响。1.1.1 碱金属与碱土金属氧化物 未改性的碱土金属本身具有活性,而加入碱金属后,可能引起晶格畸变,增加了活性中心,并减少了表面积,防止甲烷的深度氧化,从而提高了催化剂的活性和选择性。碱土金属氧化物催化剂(MgO 、CaO 、SrO 、BaO )的OC M 活性的高低在于它们的碱性强弱,碱性越强,活性越高。将两种(以上)碱土金属氧化物(盐)复配使用,OC M 反应活性与C 2选择性明显提高,以S O 422、C O 32-、NO -3取代氧构成的含盐催化剂稳定性更好[4],以碱金属促进的碱土金属氧化物因碱性位数目的增多和对非选择性氧化物的抑制剂[5]使甲烷的转化率(X CH 4)和C 2的选择性(S C 2)大大提高,选 — 45—第19卷第4期2005年4月 化工时刊Chemical Industry T ime s Vol.19,No.4 Apr.4.2005
