Are people less or more happy when they get older? A study in 2018 found that people generally become happier and experience less worry after age 50. In fact, it found that by the age of 85, people are happier with their life than they were at 18.
Arthur Stone in the Department of Psychiatry and Behavioral Science at Stony Brook University in New York led the study. His team found that levels of stress were the highest among adults between the ages of 22 and 25. 1.
Happiness was the highest among the youngest adults and those in their early 70's. But the people least likely to report feeling negative emotions were those in their 70’s and 80’s. The survey also found that men and women have similar emotional patterns as they grow older. 2.The researchers also considered possible influences like, having young children being unemployed or being single. Bu, they found that influences like these did not affect the levels of happiness and well-being related to age.
3. One theory is that, as people get older, they become more than thankful for what they have and have better control of their emotions. They also spend less time thinking about bad experiences.
4.In another study, people in their 80’s reported the fewest problems with the quality of their sleep. The original goal was to confirm the popular belief that aging is connected with increased sleep problems. 5.But except for that, people reported that they felt their sleep quality improved as they got older.
A. So why will happiness increase with age?
B. Researchers surveyed more than 150, 000 American adults.
C. At that time, the people were between the ages of 18 and 85.
D. Stress levels dropped sharply after people reached their 50's.
E Happiness is not the only thing that apparently improves with age.
F. The survey did find an increase during middle age, especially in women.
G. However, women at all ages reported more sadness, stress and worry than men.
AIDS may be one of the most undesirable diseases in the world. Luckily, there is now hope for AIDS patients.
According to a recent paper published in the New England Journal of Medicine，Chinese scientists have successfully used CRISPR technology -a method of gene editing-to treat a patient with HIV. While it may not have cured the patient fully, it still represents a huge step forward in fighting the disease.
The patient was a 27-year-old Chinese man who was diagnosed with both AIDS and acute lymphoblastic leukemia (淋巴母细胞白血病), a type of blood cancer. Despite his bleak situation, doctors offered him a little hope: a bone marrow (骨髓) transplant to treat his cancer and an experimental treatment for his HIV. They used this chance to edit the DNA in bone marrow stem cells (干细胞) from a donor before transplanting the cells into the patient.
Specifically, the treatment involved using the gene-editing tool CRISPR-Cas9 to delete a gene known as CCR5, which encodes (给…编码) a protein that HIV uses to get inside human cells. Without the gene, HIV is unable to enter cells. Talking about the gene, lead scientist Deng Hongkui told CNN, “After being edited, the cells and the blood cells they produce have the ability to resist HIV infection.” Nineteen months after the treatment, the patients leukemia was in complete remission( 缓 解 ) and donor cells without CCR5 remained, according to the research paper.
Though the transplant didn't cure the man’s HIV, it still showed the effectiveness of gene-editing technology, as there was no indication of any unintended genetic changes-a major concern with past gene-editing treatment experiments. Amesh Adalja, a senior scholar at the Johns Hopkins Center for Health Security in the United States, who was not involved in the study, praised the treatment. “They did a very creative experiment, and it was safe,” he told Live Science. “It should be viewed as a success.”
Deng believes gene-editing technology could “bring a new dawn” to blood related diseases such as AIDS and sickle-cell anaemia ( 镰 状 细 胞 贫 血 ). “Thanks to this new technology, the goal of a functional cure for AIDS is getting closer and closer,” he said.
1.The underlined word “bleak” in Paragraph3 probably means “______”.
A.hopeless
B.unstable
C.embarrassing
D.unique
2.How did the treatment fight against HIV?
A.By identifying and killing HIV.
B.By changing the structure of HIV.
C.By preventing HIV entering cells.
D.By removing a protein HIV feeds on.
3.What is the result of the treatment?
A.Gene-edited cells are able to resist HIV infection.
B.The number of cells infected by HIV has decreased.
C.CCR5 and other genes in the patient's cells are changed.
D.Unintended genetic changes have taken place in the patient's cells.
4.What can we know about the experiment?
A.It pointed out the problems of gene treatment.
B.It provided a new way to cure AIDS patients fully.
C.It could offer a safe treatment for blood-related diseases.
D.It was the first example to use gene-editing tool to treat AIDS.
Something strange has been happening to me lately: Women in the street have been telling me I'm brave.
My act of courage isn't much-I just stopped coloring my hair. I had brown hair that started going gray when I was 30. So, like a lot of women, I started dyeing (染)it. It was expensive and time-consuming. And my hair grows fast, so I needed to go back to the hair salon(美发厅) every 5 weeks.
Many people seem to enjoy holding onto their youth for as long as possible, giving off the impression that they don' t have much wisdom or many accomplishments. But our hair starts to turn gray and suddenly we start spending $500 or more a year to cover something our male colleagues don’t need to cover.
Of course, People should do what they want with their own body -my mother is 91 and still has "blond" hair, and why not? I just wish more of us would feel that it was OK to be ourselves, because going gray has done more for me than saving me time and money.
I like my natural hair, just as it is. I like how it has got curly and full again. It is recovering after years of being damaged by chemicals. I also like that it has given me some needed attitude in a society that makes youth seem so important, while being against maturity. It reminds me that I'm not a kid anymore - and this isn't a bad thing. Not being a kid anymore means I read the books I want, and not the books i feel I should read. It means not wasting my time at events I don' t need to attend when I’d rather be with my family and friends.
When I see my hair in the mirror, it's a reminder that my time is limited, and I should spend it doing what matters. There's nothing shameful about growing older And pretending it's not happening is a way of giving up our power.
I see my gray hair as a little act of rebellion(反叛)against the idea that people lose value as they age, instead of gaining it. I see gray hair as my "flag" and I'm letting it fly proudly.

If there was a subject at school that made me anxious, it was science. Maybe that’s because in my tenth grade, I couldn't understand my physics teacher's instructions, causing me to accidentally set fire to the classroom. So, when my husband and I decided to home-school our daughters, we made a deal: he would teach science, while I would handle everything else. But that’s not how things have been going these past few weeks, since my husband has been too busy to teach the girls.
Recently, while out on my morning hike before starting lessons, I noticed that the sky was a beautiful blue, and the air was filled with the sweet smell of flowers. That s why I decided that the day’s lessons would be taught outside, although I remembered that my daughters hadn't had any science classes from my husband for a while.
I returned to the house to get the girls ready. We headed up into the forest, settling ourselves by a pond that rarely has any visitors. My daughter Saoirse started to pick up pond weeds and catch frogs, while my other daughter Ula looked at me, waiting to be instructed. I handed her a drawing board and colored pencils. "We wait, "I told her, " and see if something comes along. In the meantime, just draw what's around you.”
We worked for more than an hour, hardly speaking. A bird flew across the water, and then settled in a front of a fallen tree. I quickly told Ula, worried that she’d not seen the creature. But she had, and she started drawing it. An hour later, she’d not finished her picture and I stared down at it. She drew the bird on her paper with amazing accuracy. But there was one other interesting fact about this drawing: she also drew me, sitting beside her.
I realized, as I stared at this child's drawing of us watching a bird, how I'd lived for 40 years, gathered 10 years of higher education, and never understood the foundation of science before this moment. The foundation of science is a sense of wonder; it isn't about accurately reciting words from a textbook. It is first and foremost about stepping outside our busy lives and amazing at the world around us.
1.How did the author feel about science when in school?
A.She was nervous about it. B.She was fond of it.
C.She was confused about it. D.She was eager for it.
2.The underlined word“it” in Paragraph4 refers to“ ”
A.the fallen tree B.the forest
C.the bird D.the picture
3.Which of the following best describes Ula?
A.She's very outgoing. B.She's good at observing.
C.She's very hard-working. D.She shares interests with her sister.
4.What is the foundation of science in the author's opinion?
A.Attention to accuracy.
B.Curiosity about the outside world.
C.Determination to find out the truth.
D.Ability to understand teachers' instructions.

请阅读下面内容，并按照要求用英语写一篇150词左右的文章。
P= professor; S=students (In a philosophy class)
P: We all have this one life to live. A fleeting shadow amongst all that exists in this vast universe. We have the ability to accomplish anything, truly anything, if we use our time wisely.
P: (putting some golf balls into the jar) Is this jar full?
S: Yes.
P: (after add some pebbles into the jar) Is it full now?
S: Yes.
P: (after inserting some sand into the jar) How about now, is the jar full now?
S: Yes.
P: Good… (pouring some beer into the jar)
S: … (laughing, smiling, thinking, …)
P: Now I want you to recognize that this jar represents your life. The golf balls are the important things, your family, your friends, your health and your passions. The pebbles are the other important things, your car, your job, your home. The sand is everything else, the small stuff.
P: Now if you put the sand in the jar first you won’t have room for the pebbles or the golf balls. The same is true in life. If you spend all your energy and your time on the small stuff, you won’t have time for all the really important things that matter to you.
P: Pay attention to the things that are critical to your happiness. Take care of the golf balls first. The really important things. Set your priorities. Because everything else is just sand.
S: Professor, what does the beer represent?
P: I’m glad you asked. It goes to show that no matter how full your life may seem to be, there is always room for a couple of beers with a friend.
