The first foreign language I never learnt was French, but it didn’t go very well. My mother asked our neighbor teach me when I was seven. French wasn’t his native languages, but he used to live in France, so he could speak a little. However, I learnt very little until I didn’t feel it related to my daily life anyway. When I entered into senior high school, my attitude to language learning changed. I decided to learn Latin, that I’ve always been interested in because I want to study law. Learning Latin wasn’t a struggle for myself for this reason. Soon I begin to read classic books in Latin. Read those books opened a window for me to another world or gave me a new point of view on my own world.
阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式，并将答案填写在答题卡相应的位置上。
If you’ve ever ridden public transport, you’ve probably heard snoring(打鼾) and found someone sleeping in the seat across from you. The natural vibration(震动) of buses and subways 1.(make) us feel sleepy, according to a new study in Science Alert.
Why? It’s all about sensory input-information going to your brain. On a bus, your senses give you 2.(continue) and repeating information. For example, the air conditioner and engine create constant white noise. Meanwhile, you are sitting still and your 3.(surrounding) don’t change. The vibrations of the engine are also opening. Your brain has almost no new information to process.
Repeating information will be 4.(ignore) eventually and your brain will enter a low-energy state. The fact that you fall asleep quickly with your eyes 5.(close) on a bus is because your brain gets used to all the repeat.
“When you’re tired, it doesn’t take much time 6.(start) nodding off and we’ve found that the gentle vibrations made by car seats 7. you drive can loose(使放松) your brain and body,” said Stephen Robinson, 8. researcher from the RMIT University in Melbourne, Australia.
Robinson’ s team mentioned 15 volunteers’ heart rate variability(心率变异性)—a well-known indicator of sleepiness. This line of research can assist in the development of practical and relevant guidelines for limiting 9.(expose) to vibrations in the car industry. Robinson believed that the research could be helpful 10. improving road safety. “We hope that future car seat designs can build in features to disturb this lulling effect and fight vibration-induced(震动引起的) sleepiness,” he said.

To my____，the hospital was well equipped, with an X-ray machine and a blood analyzer. That first voyage was a learning experience, a ____ schedule full of safety drills. There was so much new information to______ . Even remembering which uniform to wear each day was a_____ . Most confusing, I often forgot to ______my clock when the ship crossed time zones.
As a doctor, I was ______for the 600 crew. and I was on call for the entire ship. Far from ____ seasickness and sunburn, I had to deal with other diseases, for my patients were wide and varied. The ship’s medical center was ____ a floating emergency room, and we didn’t have a team of specialists on hand for a second _____ . With long and unpredictable hours, it required mental _____ .
As you can guess, many of the passengers were elderly. Heart attacks don’t ____ geography and emergency evacuations (疏散)were difficult to arrange. I recall one such patient, who was taken off the ship halfway through the Panama Canal .After a _____ ride in an old ambulance, I was relieved that the patient ______long enough to arrive at the hospital in Panama City. ____ , there were several unexpected benefits to the job. I regularly ______the passenger facilities (设施)and I even hosted my own table of passengers in the evenings. On rare days off, I_____ as a tour guide on trips ashore. I got to fly over Alaska in a seaplane and watched a ballet in St Petersburg.
Now, I understand being a ship doctor is not a job-it's a way of _____ .One year at sea became two. I lost my career ambitions, _____I redefined happiness in my life.

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

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.

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.
