When you go to the doctor, you receive a diagnosis (诊断) and a treatment. However, with the continued use of technology in healthcare, the process of diagnosing and treating patients has been changing.
Artificial Intelligence (AI) can help doctors analyze a patient’s symptoms and offer the best treatment. With new advancements in medical technology, it makes receiving medical care faster and more accurate. Technology companies provide the data analyzing tools that are necessary to analyze the efficiency (效率) of the healthcare system, which makes the care more efficient and improves the quality of care. Technology is also being used to help patients achieve their health goals as well as help patients when doctors are not present. Patients can rely on apps, trackers, and programs to remind them to have themselves checked, track their symptoms or call for help.
In the United States, the creation of AI technology has done better than that of other countries. However, compared to some countries like Canada, the United States has failed in using AI in its healthcare system. The reality is that AI is not used in medical care because of the high costs and the insurance barriers. It is the private healthcare system that puts all the costs on consumers of healthcare.
Undoubtedly, using more technology in healthcare can be better for the system. It can improve efficiency, limit errors, and cut down waiting time. But the high cost of creating this technology can make it difficult to provide service in every hospital and healthcare clinic in the United States. It also changes the practice of medicine, making it less personal and more about the technology. Doctors wouldn’t have to rely on their own knowledge and skill but could turn to robots and computers for help or use better equipment to help them perform a procedure.
As the medical field continues to change, so will the technology that is used in the medical field, making receiving medical care a highly computerized process that could improve the health of the population.

I was watching Family Feud a few years ago when they asked something like “What’s one thing you want your pilot to be?” And one of the answers was “A man.” Yes, I was upset, but that just inspired me more. It’s rare enough to see women pilots — for the first two years of my flight training classes, I was the only female student — and even more unusual to see a pilot who’s a woman of color. Black women make up about 7 percent of the U.S. population, but less than 1 percent of pilots. And of course, most of them are a bit older than I am. I just graduated from high school in May.
My mom is crazy about aviation (航空), so she always took me to air shows when I was younger. We’d watch the Thunderbirds or Blue Angles, and I’d get pilots’ autographs (亲笔签名). With her encouragement, I started taking lessons after I turned 12. Friends would ask me to hang out, and I’d say, “Sorry, I have a flight” — they’d look at me as if I had four heads. But the air felt like where I was supposed to be.
Flying is amazing for many reasons. You can see the beauty only from above and visit impressive places. But to me, one of the coolest things is being in charge of the plane and holding the controls. I plan to fly the big jets as an airline transport pilot, which means doing lots of ground training, banking 1,500 hours of flight time, and earning a bunch of certificates.
On my first plane ride when I was 4, the flight attendants (乘务员) gave me a little pin with wings. We took a picture of me standing next to the captain. Who would have guessed that someday I’d be sitting in his seat?
1.Why did the author feel upset after hearing the answer?
A. It was too simple. B. It dealt with racial differences.
C. It talked about pilots negatively. D. It was prejudiced against women.
2.What does the author say about black women?
A. They are uncommon sights in flight training classes.
B. They make up 7 percent of the U.S. pilots.
C. Most of them are high school graduates.
D. Few of them are interested in aviation.
3.What’s the author’s mom’s attitude to her becoming a pilot?
A. Skeptical. B. Supportive.
C. Unconcerned. D. Disapproving.
4.What happened when the author was four years old?
A. She sat in a captain’s seat. B. She had a hard plane ride.
C. She was gifted a winged pin. D. She helped some flight attendants.

“There is a common misconception that vegetarians have limited food choices. Just the opposite is true. Vegetarians commonly eat a wider variety of foods than most meat eaters.”

“The more I got educated about cruel treatment, it really was a no-brainer to become a vegetarian. You know, no one would barbecue their family dog. You know, a pig or a chicken isn’t different. They are just as gentle as a dog or a cat...”
—Public service announcement, Mike Ness
“I’m not a vegetarian because I enjoy eating meat. Meat is nutritious food, and I believe there are ways to eat meat that are in keeping with my environmental and ethical (道德的) values. I don’t make the decision to eat meat lightly. Meat-eating has always been a messy business, shadowed by the shame of killing...
“I have a sincere respect for vegetarians, for they have actually done the work of thinking through the consequences of their eating decisions, something most of the rest of us have not done. My own examination of those consequences has led me to the conclusion that eating a small amount of meat from certain kinds of farms is something I can feel good about.”
―“Animal Welfare: FAQ & Useful
Links”, Michael Pollan
“The centerpiece of a truly healthy diet must be animal foods. That means a large part of meat, seafood, eggs or raw dairy at just about every meal. That is how one recovers from vegetarianism and builds lasting health and strength.”

Last week, I took part an English speech contest. There are twelve students in the final contest. I was one of the lucky student. Fifteen minutes after my turn, I picked my topic and prepared for it. I wrote down the outlines and organized what I was going to say. However, when I stood in the front of all the judges and students, I was extreme nervous. Then I took a deep breath to relax me and started my speech. The result was not good, because I regarded it as a challenge, which process was the most important.
Having learnt a lot from the contest, I am sure I will do it much well next time.
