From the time I turned 12, a white gardenia(栀子花) was delivered to my house every year on my birthday. No card came 16 it. Calls to the flower-shop were of no help. After a while I stopped 17 (try) to discover the sender's name and just delighted in 18 beautiful white flower.
But I kept on imagining 19 the giver might be. Some of my 20 (happy) moments were spent daydreaming about the sender. My mother encouraged these imaginings. She'd ask me if there was someone for whom I had done special kindness. Perhaps it was the old man across the street whose mail I'd delivered during the winter. 21 a girl, I had more fun imagining that it might be a boy I had run into.
My father passed away one month before I graduated. I felt so sad 22 I became completely uninterested in my upcoming graduation dance, and I didn't care if I had a new dress or not.

Wearing glasses and a T-shirt, one can hardly relate Chai Huilong to his job – a chive (韭菜) farmer. Two years ago, Chai graduated from Tianjin College of University of Science and Technology Beijing. He took over his parents’ 20,000-square-meter plot of land and set up a business: growing Chinese chives.
But instead of growing chives in the traditional way, Chai plants them in garden pots and sells them directly to customers through an online store. Now his family earns 10 million yuan a year.
Chai is one of many young people who have found great career opportunities in rural areas. They make good use of their agricultural knowledge and new technologies, and benefit from supportive policies. When Chai came up with the idea of growing chives in pots, he was not sure about running his own business. But Youth Business China, a non-profit program backed by the government, gave him “courage and strength”, he said.
The program helps promote youth entrepreneurship(创业). It offers 30,000 to 50,000 yuan in start-up funding to young people who have promising ideas. It also assigns each of them a tutor who provides guidance on spending fund money and operating the company. “My tutor makes sure I’m on the right track,” said Chai. “Without him, I will lose heart.”
Local governments also encourage young graduates to pursue a career in rural areas. They often provide special subsidies to those who run agriculture-related businesses. For example, Chai was able to buy agricultural machinery and tools at a discount.
“Besides, be prepared for a lot of mental pressure if you plan to be a modern farmer,” said Chai.
“My relatives and friends regard farming as a less respectable job. But being a farmer is just my job, not my identity,” said Chai.
So far, his products have been sold to places as far away as Dubai in the United Arab Emirates. Chai is even more optimistic that he can further broaden the definition(定义) of farming in the future.
26. How does Chai sell his Chinese chives to consumers?
A. With the help of his parents.
B. By advertisement.
C. With the help of the government.
D. By running an online shop.
27. What can we infer about Chai Huilong in Paragraph 3?
A. He benefited a lot from the government.
B. He was good at running his business.
C. He was an expert in growing chives.
D. He majored in agriculture.
28. Chai became more confident mainly because _________.
A. he worked hard
B. he received all the funding
C. his tutor gave him encouragement
D. his idea confused him
29. The underlined word “subsidies” in Paragraph 5 is closest in meaning to ______.
A. methods
B. aids of money
C. products
D. skills
30. What is the passage mainly about?
A. A successful chive farmer.
B. A path to setting up a business.
C. A non-profit program--Youth Business China.
D. A learned graduate.
B
Being a teenager is a difficult challenge. You frequently disobey the rules that parents ask you to do. So parents often do not know what to expect. Many of them often find it difficult to understand what you need during your growing. They don’t know whether what you are doing is for independent action or for rebellion.
Some adults consider adolescence as a period of friction(摩擦), change and problems. For you it’s a time of school pressures, girl friends, boy friends or your future.
It's easy to understand why so many people find this a difficult time. But once it’s over, you will realize that most of your parents’ annoyed behavior is motivated by feelings of love and concern. You think adolescence can be a trying time. But if you communicate with your parents, and try to understand each other, this period will be less trying and more fun for you all.
Below are a few tips to improve the communication you have with your parents: Be honest with your feelings while talking. Your parents are of great help to you, but they don’t know what’s going on in your life if you don’t tell them.
If your parents upset you by grounding, you don’t immediately take the defensive side. Make sure you talk to your parents when you’re not emotionally upset. If you start yelling or crying, you won’t be able to express your important feelings.
Listen to what your parents have to say. If you’re getting a chance to speak what’s on your mind, it’s only fair to give the same opportunity to your parents. If you listen to what they say, you may learn that you’ve been misinterpreting their feelings.
When you’re talking to your parents if they say something you disagree with,
don’t immediatel y overreact. Give them a chance to express their feelings and then calmly explain why you may disagree with them. Try to identify what you need from them and tell them if they may not know. Only when you follow the above advice, can you have a good time as a teenager.
31. What is the purpose of the passage?
A. To tell teenagers some advice on how to talk with parents.
B. To describe some troubles on t eenagers’ growth.
C. To describe to teenagers a difficult challenge.
D. To explain teenagers' feelings and problems.
32. Who are the intended readers of the passage?
A. Parents.
B. Doctors.
C. Teenagers.
D. Teachers.
33. The underlined word "trying" in Paragraph 3 is closest in meaning to .
A. annoyed
B. difficult
C. lovely
D. effective
34. Which isn’t the positive advice to improve the communication you have with your parents?
A. Take the defensive actions.
B. Be honest with your feelings.
C. Listen to your parents.
D. Identify your need.
35. When your parents don’t know what your life is like, you shouldn't ________.
A. misunderstand them
B. express your important feelings
C. react too much
D. tell a lie about your feelings

What makes all of these especially unusual is that Ruggiero, 24, has only one leg. When he was a 19-year-old musical theater student at New Jersey’s Montclair State University, Ruggiero had a rare bone cancer in his right leg. Finally his leg would have to be amputated (截) below the knee. Such a setback could have easily ended the career of a less tough person,but Ruggiero,who has been dancing since he was five,now puts the experience into his performance. His show, “The One-Legged Song and Dance Man: Volume 3”,explains how he returned to dance just 18 months after the amputation. His dance now relies on the use of a peg leg(假肢) ,he explains. The secret to his surprising success, he says, was being a “stubborn”patient who refused to give up on his dance and performing studies, despite the advice of his doctor. “It was a real setback,but after it was all over,I said, ‘You know what? I need to pick up right where I left off and continue my career, ’”Ruggiero said. Ruggiero has come to view his peg leg as an instrument. “Tap dancers—they’re always calling themselves musicians, and their feet are their instrument, ” he said. Noting that many audience members will never have seen a one-legged dancer 2019年临沂市高三化学一模试题（有答案）可能用到的相对原子质量：HI C 12 O 16 Cl 35.5 Fe 56 Cu 64 As 75. 第I卷(选择题共42分) 选择题(本题包括14小题。每小题只有一个选项符合题意，每小题3分，共42分) 1.化学与生产、生活联系密切，下列说法正确的是 A.常用作净水剂的KAl(SO4)2和漂白粉都是强电解质 B.维生素C具有还原性，在人体内起抗氧化作用 C.对“地沟油”进行分馏可以获得汽油发动机的燃料 D.碘是人体必需的微量元素，所以要多吃富含高碘酸的食物 2.下列有关叙述正确的是 A.非金属氧化物一定为酸性氧化物 B.和互为同位素，化学性质相似 C.根据是否能产生丁达尔效应，将分散系分为溶液、浊液和胶体 D.已知红磷比白磷稳定，则 3.下列有关实验的叙述正确的是 A.金属钠着火时，立即用沾水的毛巾覆盖 B.实验室可用右图所示装置制取饱和氨水 C.硅酸钠溶液保存在带橡胶塞的细口瓶中 D.用容量瓶配制溶液，定容时俯视刻度线，所配溶液浓度偏 小 4.下列有关元素化合物的性质叙述正确的是 A.SO2、NO2都能与水反应，其反应原理相同 B.Na2O2在空气中长期放置最终变为NaHCO3粉末 C.既能与酸反应;又能与碱反应的物质都是两性化合物 D.可用KSCN溶液检验FeSO4溶液是杏氧化变质 5.某有机物的结构简式如右图所示，下列说法错误的是 A.与乙酸互为同系物 B.含有两种含氧官能团 C.可使溴的四氯化碳溶液褪色 D.既可以发生取代反应又可以发生加成反应 6.制备食用碘盐(KIO3)原理之一为：，下列说法正确的是 A.向KClO3溶液中滴加AgNO3溶液得到白色AgCl沉淀 B.反应过程中I2置换出Cl2，由此可推断非金属性I CI C.KClO3和KIO3均属于离子化合物，都只含有离子键 D.制备KIO3的反应中氯元素被还原 7.下列说法正确的是 A.N和As属于第VA族元素2，N原子得电子能力比As原子强 B.族序数等于其周期序数的元素一定是金属元素 C.元素周期表中，位于金属和非金属交界线附近的元素属于过渡元素 姓名： ____________考号： __________班级： _________得分： 高考英语周考英语答题卡 1[ A ][ B ] 2[ A ][ B ] 3[ A ][ B ] 4[ A ][ B ] 5[ A ][ B ] 26[ A ][ B ] 27[ A ][ B ] 28[ A ][ B ] 29[ A ][ B ] 30[ A ][ B ] 41[ A ][ B ] 42[ A ][ B ] 43[ A ][ B ] 44[ A ][ B ] 45[ A ][ B ] [ C ] 6 [A][ B ][ C ]11[ A ][ B ][ C ]16[ A ][ B ][ C ]21[ A ][ B ][ C ][ D ] [ C ]7 [A][ B ][ C ]12[ A ][ B ][ C ]17[ A ][ B ][ C ]22[ A ][ B ][ C ][ D ] [ C ]8 [A][ B ][ C ]13[ A ][ B ][ C ]18[ A ][ B ][ C ]23[ A ][ B ][ C ][ D ] [ C ]9 [A][ B ][ C ]14[ A ][ B ][ C ]19[ A ][ B ][ C ]24[ A ][ B ][ C ][ D ] [ C ]10 [A][ B ][ C ]15[ A ][ B ][ C ]20[ A ][ B ][ C ]25[ A ][ B ][ C ][ D ] [ C ][ D ]31[ A ][ B ][ C ][ D ]36[ A ][ B ][ C ][ D ][ E ][ F ][ G ] [ C ][ D ]32[ A ][ B ][ C ][ D ]37[ A ][ B ][ C ][ D ][ E ][ F ][ G ] [ C ][ D ]33[ A ][ B ][ C ][ D ]38[ A ][ B ][ C ][ D ][ E ][ F ][ G] [ C ][ D ]34[ A ][ B ][ C ][ D ]39[ A ][ B ][ C ][ D ][ E ][ F ][ G ] [ C ][ D ]35[ A ][ B ][ C ][ D ]40[ A ][ B ][ C ][ D ][ E ][ F ][ G ] [ C ][ D ]46[ A ][ B ][ C ][ D ]51[ A ][ B ][ C ][ D ]56[ A ][ B ][ C ][ D ] [ C ][ D ]47[ A ][ B ][ C ][ D ]52[ A ][ B ][ C ][ D ]57[ A ][ B ][ C ][ D ] [ C ][ D ]48[ A ][ B ][ C ][ D ]53[ A ][ B ][ C ][ D ]58[ A ][ B ][ C ][ D ] [ C ][ D ]49[ A ][ B ][ C ][ D ]54[ A ][ B ][ C ][ D ]59[ A ][ B ][ C ][ D ] [ C ][ D ]50[ A ][ B ][ C ][ D ]55[ A ][ B ][ C ][ D ]60[ A ][ B ][ C ][ D ] 第二节：语法填空（15 分） 61.____________ 62. _____________ 63. ______________ 64. ________________ 65. ____________ 66._____________ 67. _____________68. _______________69. ________________ 70. ___________ 第一节：短文改错（10 分） As we all know, life is very much beautiful and precious; therefore we should admire but value it.
