Accept life as it is. I learned how to do it from my father. In fact, he did not teach me that when he was strong and healthy, but when he was 41 and ill.
My father was once a strong man who loved being active, but a terrible illness 42 all that away. Now he must lie down quietly in the hospital all day. Nothing seems to belong to him. He can no longer walk, even talking is difficult. One night, I went to visit him with my sisters. We started to 43 life, and I told them about one of my thoughts. I said that we must very often give things up 44 our youth, our beauty, our friends and so on. However, it always seems that after we give something up, we get something new in its place. Then suddenly my father opened his mouth. He said, “But, Peter, I gave up almost 45 ! What di d I get?” I thought and thought, but I couldn’t think of anything to say. To my 46 , he answered his own question, “I get the love of my family.” I looked at my sisters and saw tears in their eyes, 47 hope and thankfulness. I was also 48 by his words.
After that, when I begin to feel angry at someone, I remember his words and become calm. If he could replace(替代) his great pain with a feeling of love for others, then I should 49 learn to give up my small anger. In this way, I learn the power of acceptance from my father. Until now, I am still really 50 for such a talk between father and son.

One day, I picked up my daughter Eloise from school and went to the supermarket for a few things. I was hoping to be in and out quickly.
I found a short line with just one person ahead of me. It was an elderly woman, and she was paying for her things with only change. After a long day at work, I was a little angry with this woman.
But then I watched the young clerk(职员). He helped her count her change, slowly and gently taking it from her shaking hands. I listened to him repeatedly say to her, “Yes, ma’am.” When she asked if she had enough to buy a bag, he told her she did. Then he went two lines over to get one for her. Never once did this clerk get angry. He was patient and kind.
As I was watching him, I saw Eloise was too. I realized my daughter was learning an important lesson from a complete stranger. When the woman was finished, the clerk began ringing up my things and thanked me for my patience. I thanked him too. I found the manager and told him about the clerk’s kindness and patience.

Have you heard about the periodic table (元素周期表) lately? Well, there’s some big news about this special table, but first, remember that the periodic table is used for all the elements（元素）, or things that make up our world.
Elements are all around us. Iron is one of the most common elements found on the earth. You probably know the element oxygen (氧), which is the element that we breathe in all the time. And elements can combine (结合) to make new things like H2O. This is hydrogen (氢) and oxygen put together, also known as water! Learning about these things helps us better understand the world we live in.
But have you ever noticed something missing in the periodic table? There were already 114 elements. But the seventh row of the table was not finished, until now!
In December, scientists from the IUPAC（国际纯粹与应用化学联合会) found the four elements that were missing. They are elements 113, 115, 117 and 118.
“To scientists, this is of greater value than an Olympic gold medal,” Ryoji Noyori, a Nobel honored chemist said.
The new elements are heavy metals and were made in lab. These kinds of elements can’t be found in nature. Scientists are still looking for ways to use these elements, and other elements in the eighth row in our daily lives.
Scientists have been working on this for 10 years, but the work is not done. Now they will prepare to look for “element 119 and beyond”. But for now, be mindful (留心的) when you read your science books because the periodic table might be outdated (过时的).
58.In Paragraph 2, the writer mainly talks about_________.
A. examples of some common elements
B. the importance of oxygen
C. how elements make new things
D. how to learn about elements
59. The newly found elements are ________.
A. elements 113, 114, 115, 116
B. elements 113, 114, 117, 118
C. elements 113, 115, 117, 118
D. elements 113, 115, 117, 119
60. The underlined word “beyond” means ________ in the last paragraph.
A.更前面
B.更后面
C.更上面
D.更里面
61. Which of the following about the new elements is NOT true?
A. They are heavy metals.
B. They were made in labs.
C. They can’t be found in nature.
D. They are widely used in our daily lives.
D
The classic tale of Alice’s Adventures in Wonderland (《爱丽丝梦游仙境》) is a book many children grow up with. And this year it is celebrating its 150th birthday.
In the story, the 7-year-old Alice is running after a white rabbit, but she accidentally falls down a rabbit hole. She enters a world called Wonderland, and this is where the adventure (冒险) begins.
In Wonderland, there seems to be no rules or logic (逻辑). Alice meets many strange and wonderful characters. A cruel queen says she is going to cut off someone’s head every two minutes. A cat smiles so big that its lips almost reach its ears. And strange things happen to Alice, too. Her body grows and shrinks (缩小) during her time in Wonderland.
Alice is very annoyed because she doesn’t unders tand this strange place. But in fact, the story is about an innocent (天真的) children trying to make sense of the strange adult world, said Professor Will Brooker of Kingston University London.
When British author Lewis Carroll wrote the story in 1865, its special style and humor made it a classic of its time. It even created some phrases we still use today. When people say “down the rabbit hole”, they mean to make a choice where the result is unknown.
The story is also on show through different artworks all over the world. There are paintings and music videos based on the story. In summer 2010, the movie Alice’s Adventures in Wonderland was put on in movie theatres.

B. avoid
C. need
D. attract
64. Ac cording to the passage, the story of Alice’s Adventures in Wonderland isn’t on show through _______.
https://www.doczj.com/doc/9b11598263.html, news
B. paintings
C. music videos
D. movies
65. When someone makes a decision, he says he is going “down the rabbit hole”. It means_________.

It took 22 years, 36 films and five nominations (提名) for Leonardo DiCaprio to finally win an Oscar.(奥斯卡)

2021届重庆市第一中学高三上学期第一次月考数学试题 一、单选题 1．设集合(){} ln 1A y y x ==-，{ B y y ==，则A B =（ ） A ．[)0,2 B ．()0,2 C ．[]0,2 D ．[)0,1 【答案】A 【解析】先分别利用对数型函数以及指数型函数求值域的方法求出集合,A B ，注意集合中的代表元素，再利用集合的交集运算求解即可. 【详解】 ∵(){} ln 1A y y x R ==-=， { [)0,2B y y ===， ∴[)0,2A B =. 故选：A. 【点睛】 本题主要考查了集合间的运算以及对数函数和指数函数.属于较易题. 2．设a ，()0,b ∈+∞，A =，B =，则A ，B 的大小关系是（ ） A ．A B < B ．A B > C ．A B ≤ D ．A B ≥ 【答案】B 【解析】根据题意计算做差可得22A B >，得到答案. 【详解】 由a ，()0,b ∈+∞，得0A = >，0B => 2 2220A B -= -=>， ∴22A B >，故A B >， 故选：B. 【点睛】 本题考查了做差法比较大小，意在考查学生的计算能力和推断能力. 3．已知直线l 是曲线2y x =的切线，则l 的方程不可能是（ ） A ．5210x y -+= B ．4210x y -+= C ．13690 x y -+=
D ．9440x y -+= 【答案】B 【解析】利用导数求出曲线2y x =的切线的斜率的取值范围，然后利用导数的几 何意义判断各选项中的直线是否为曲线2y x =的切线，由此可得出结论. 【详解】 对于函数2y x = ，定义域为[)0,+∞，则22 y '= +>， 所以，曲线2y x = 的切线l 的斜率的取值范围是()2,+∞. 对于A 选项，直线5210x y -+=的斜率为5 2 ，令522y '=+=，解得1x =，此 时3y =， 点()1,3在直线5210x y -+=上，则直线5210x y -+=与曲线2y x =相切； 对于B 选项，直线4210x y -+=的斜率为2，该直线不是曲线2y x =的切线； 对于C 选项，直线13690x y -+=的斜率为 13 26 >， 令13 2 6 y '= += ，解得9x =，此时21y =， 点()9,21在直线13690x y -+=上，所以，直线13690x y -+=与曲线2y x =相切； 对于D 选项，直线9440x y -+=的斜率为 9 24 >， 令9 2 4 y '= = ，解得4x =，此时10y =， 点()4,10在直线9440x y -+=上，所以，直线9440x y -+=与曲线2y x =相 切. 故选：B. 【点睛】 本题考查利用导数的几何意义验证函数的切线方程，考查计算能力，属于中等题. 4．中国传统扇文化有着极其深厚的底蕴．一般情况下，折扇可看作是从一个圆面中剪
