21、Tips for Traveling with Your Parents
Many of us have fond memories of traveling with our parents as children,which makes going on vacation with them as adults much more special.【1】But depending on your parents'age,health, and preferences,going away together can also bring challenges.here are ups to help make sure everyone has a good time.
Find a point person.
【2】It's best when there is a single point person for planning who becomes the advocate for all members of the travel party.If mobility is an issue,try planning with Accessible GO,a platform that enables travelers to search by city or interest for wheelchair-friendly activities.
Build in options.
【3】Being aware of each traveler's fitness and activity level is crucial in designing a route.For example,start with a slow-paced activity that everyone can enjoy such as wine tasting，and have more-energetic activities,like hiking.【4】
Consider buying insurance.
Emergencies--such as a missed flight or lost luggage--can happen at any age,so it's wise to invest in travel insurance.Many policies cover medical emergencies as well as everyday travel mishaps(小事故).【5】Some insurance supplements even arrange air medical transfers to the traveler's hospital of choice.
A.Be optional.
B.It's a chance to return the favor.
C.Make sure those who get ill are well attended to.
D.As our parents are aging,they should not travel alone.
E.Be sure to do your homework as some policies are better than others.
F.Having one person in charge can significantly minimize stress and confusion.
G.The most important thing is striking a balance between activities and free time to ensure that no one gets exhausted.
22、Pianist Jean-Francois Maljean has released a piano piece to commemorate (纪念) the 2022 Beijing Winter Olympics, which kicked off with a grand opening ceremony held at the National Stadium on Feb 4. Titled For Beijing Olympics, the piano piece, which is about 3 minutes, was asked by the Chinese embassy in Belgium, with the aim of celebrating Chinese New Year and welcoming the Winter Olympics. He also wrote a song to support Wuhan in its fight against COVID-19 in 2020 and another song for Xi’an in December.
Born in Verviers, Belgium, Maljean started to learn the piano at age 6. At about 12, the classically trained pianist became interested in a diverse range of musical genres(类型), especially pop music like that of The Beatles.
He had planned to compose a song and English author Robert Murray, the pianist’s friend, even started to write the lyrics (歌词) about the Olympic Games. However, due to the short time, Maljean ended up just composing a piano piece, which was later released in the form of a music video featuring images of winter sports. “I think the piano piece works even better than a song. Since winter sports mainly give an impression of speed, I composed a mostly very fast piece, though there are some slower moments. And it works very well,” says Maljean, 68, who recorded the piece at his own studio in Belgium. Maljean recalls that he visited the capital and spent some time in China, where he was featured in a documentary for Belgian television. He traveled to many places in China, including Changchun in Jilin province, Guizhou province and Shanghai, and landed in Beijing to visit Olympic sites.
【1】What is the first paragraph mainly about?
A．The introduction of Maljean.
B．The masterpieces of Maljean.
C．Maljean’s works about China.
D．Maljean’s contribution to music.
【2】What do we know about Maljean from the passage?
A．He is a great skiing enthusiast.
B．He is a classical music composer.
C．His documentary was filmed in Belgium.
D．He travelled to several Chinese provinces.
【3】Why does Maljean think the fast piano piece is better than a song?
A．Because it reflects the features of winter sports.
B．Because he is more expert at composing pop music.
C．Because it contains Chinese classical music elements.
D．Because the lyrics are not in accordance with the music.
【4】Which of the following best describes Maljean?
A．Generous and patient.
B．Talented and caring.
C．Simple and independent.
D．Adventurous and sensitive.
23、For years, Mark Hager worked as an at-sea fishery observer, going out on New England fishing boats for days or weeks and keeping detailed records of every fish caught or thrown back. The work could be perilous: on one trip, a boat turned sideways in 20-foot seas, and Hager and the crew put on survival suits in case they had to jump overboard. But the counting was essential to protecting the ecosystem.
In the early 2000s, the fishing industry began fixing video cameras on boats, so that humans could track the data from ashore. In 2019, Hager and the Gulf of Maine Research Institute launched a company, New England Marine Monitoring, based in Portland, Maine, to provide technology support for ships using electronic monitoring. His team has to watch hours of video footage (镜头), look for each moment when a fish is discarded (丢弃), then make a note of the species and the time it was discarded. In ten hours of video, there might be 45 minutes between each case of a discarded fish.
When Hager consulted with other scientists, they came up with a new idea. Now, Hager and his team are using their notes as training data for an artificial intelligence (AI)algorithm (算法)-programming the AI to scan (扫描) the video footage and indicate points of interest along the timeline for a human to look through. “Instead of ten hours of video, we’ll be able to look at about 100 pictures, which we can do in about 20 minutes,” Hager says.
The result could save time and money, but Hager has a bigger goal. He wants to prove that AI algorithms can be used to count every fish that’s caught and discarded. To be effective, the algorithm will need to be able to identify the total volume of a fish haul (一网的捕鱼量), count containers of fish,and potentially even count and measure individual fish. Using video monitoring to count a small amount of the total catch is one thing. Using it to count the entire haul on a ship is a huge challenge — one that has never been achieved before.
【1】What does the underlined word “perilous” in paragraph 1 probably mean?
A．Well-paid.
B．Time-consuming.
C．Interesting.
D．Dangerous.
【2】What is the problem with electronic monitoring?
A．The cost is usually quite high.
B．The process is slow and boring.
C．The result is not always correct.
D．The quality of images is poor.
【3】What do Hager’s words in paragraph 3 suggest?
A．AI algorithms can be of great help.
B．Pictures prove to work better than videos.
C．Humans are more dependable than cameras.
D．Interest plays a key role in the fishing industry.
【4】What is the author’s main purpose in writing the text?
A．To encourage readers to protect the ecosystem.
B．To introduce New England Marine Monitoring.
C．To report the influence of technology on fishing.
D．To talk about the life of an at-sea fishery observer.
24、Alzheimer's AI
An estimated 5.7 million people in the U.S. have Alzheimer's disease-the most common type of dementia(痴呆）－and that number is expected to more than double by 2050. Early diagnosis is crucial for patients to benefit from the few therapies available. But no scans can deliver a conclusive diagnosis while a person is alive; instead doctors have to conduct numerous and complicated clinical and neuropsychological tests.So there is growing interest in developing artificial intelligence to identify Alzheimer's based on brain imaging.
Researchers at the University of California,San Francisco, have now successfully trained an AI algorithm(算法）to recognize one of the early signs of Alzheimer's-a reduction in the brain's glucose（葡萄糖）consumption-in positron emission tomography (PET) imaging.
The algorithm accurately predicted an eventual Alzheimer's diagnosis in nearly all the test cases, according to the study. In PET imaging, a very small amount of a radioactive compound are injected into the body, producing three-dimensional images of metabolism(新陈代谢）,circulation and other cellular activities. PET is well suited for an AI diagnostic tool because Alzheimer's leads to subtle changes in the brain's metabolism that begin years before neural(神经的） tissue starts to go downhill, says study co-author Jae Ho Sohn,a radiologist at UCSF. These changes are "very hard for radiologists to pick up,"he notes.
The algorithm was trained and tested on 2,100 PET brain images from about 1,000 people 55 years and older. The images came from a 12-year study that tracked people who would ultimately be diagnosed with Alzheimer's, as well as those with mild memory declines and healthy control participants. The algorithm was trained on 90 percent of the data and tested on the remaining 10 percent. It was then retested on a second, independent data set from 40 patients monitored for 10 years. The algorithm was highly sensitive and was able to recognize 81 percent of the patients in the first test group and 100 percent in the second who would be diagnosed with Alzheimer's six years later, on average. The findings were published in February in Radiology.
The algorithm is based on "deep learning ,a machine-learning technique that uses artificial neural networks programmed to learn from examples. "This is one of the first promising,preliminary(初步的） applications of deep learning to the diagnosis of Alzheimer's," says Christian Salvatore, a physicist at Italy's National Research Council, who was not involved in the study. “The model performs very well when identifying patients with mild or late diagnoses", he says, “but catching it in the earliest stages remains one of the most critical open issues in this field."
