21、It’s 5:00 in the morning when the alarm rings in my ears. I roll out of bed and walk blindly through the dark into the bathroom. I turn on the light and put on my glasses. The house is still as I walk downstairs while my husband and three kids sleep peacefully. Usually I go for a long run, but today I choose my favorite exercise DVD. Insanity. Sweat pours down my face and into my eyes. My heart races as I face my body to finish each movement. As I near the end of the exercise, I feel extremely tired, but a smile is on my face. It’s not a smile because the DVD is over, but a smile of success from pushing my body to its extreme limit.
Some people enjoy shopping, smoking , food, work, or even chocolate. But I need exercise to get through each day. Some shake heads when they see me run through the town. Others get hurt when I refuse to try just one bite of their grandmother’s chocolate cake. They raise their eyebrows, surprised by my “no thank you,” or by my choice to have a salad. Over the years , I have learned it’s okay to just say “no.” I shouldn’t feel sorry for refusing food that I don’t want to eat.
So what drives me to roll out of bed at 5:00 a.m.? What gives me the reason to just say no to ice cream? Commitment. A commitment to change my life with a way that reduces daily anxiety, increases self –confidence and energy, extends life and above all improves my body shape. This is the point where a smile appears on my face as I look at myself in the mirror or try on my favorite pair of jeans that now fit just right. It’s through commitment and sweat that I can make a difference within myself inside and out.

D. Because she feels a sense of achievement.
【2】What does the underlined word “commitment” in the last paragraph mean?
A. Good health. B. Firm belief.
C. A strong power. D. A regular habit.
【3】What can we learn about the author from the text?
A. She acts in a strange way.
B. She wants to look different from others.

D. She has difficulty getting along with others.
22、People with COVID-19 who are asymptomatic can spread the disease without any outward signs that they're sick. But a newly developed AI, with a keen algorithmic ear, might be able to detect asymptomatic cases from the sounds of people's coughs, according to a new study.
A group of researchers at MIT recently developed an artificial intelligence model that can detect asymptomatic COVID-19 cases by listening to subtle differences in coughs between healthy people and infected people.
Indeed, it is the Alzheimer's model that the researchers adapted in an effort to detect COVID-19.“The sounds of talking and coughing are both influenced by the vocal cords and surrounding organs.” co-author Brian Subirana, a research scientist in MIT's Auto-ID Laboratory said in a statement. “AI can pick up simply from coughs, including things like the person's gender, mother tongue or even emotional state. There's in fact sentiment strongly fixed in how you cough.”
First, they created a website where volunteers-both healthy and those with COVID-19-could record coughs using their cellphones or computers; they also filled out a survey with questions about their diagnosis and any symptoms they were experiencing. People were asked to record “forced coughs,” such as the cough you let out when your doctor tells you to cough while listening to your chest with a stethoscope.
Through this website, the researchers gathered more than 70,000 individual recordings of forced-cough samples, according to the statement, Of those,2,660 were from patients who had COVID-19,with or without symptoms. They then used 4,256 of the samples to train their AI model and 1,064 of the samples to test their model to see whether or not it could detect the difference in coughs between COVID-19 patients and healthy people.
The AI model correctly identified 98.5% of people with COVID-19, and correctly ruled out COVID-19 in 94.2% of people without the disease. For asymptomatic people, the model correctly identified 100% of people with COVID-19, and correctly ruled out COVID-19 in 83.2% of people without the disease.
But "whether or not this performs well enough in a real-world setting to recommend its use as a screening tool would need further study,"Lubinsky told Live Science."What's more,further research is needed to ensure the AI would accurately evaluate coughs from people of all ages,’’ he said.
【1】How does the AI recognize people infected with COVID-19?
A．By observing outward sick signs.
B．By identifying sounds of coughs.
C．By copying the Alzheimer's model.
D．By talking to the healthy and the infected.
【2】On what basis does the AI function as a detecting tool?
A．How people catch coughs.
B．How people perceive coughs.
C．How people make vocal sounds.
D．How people release their emotions.
【3】Which of the following isn't a part of the research?
A．Volunteers record coughs.
B．Volunteers fill out a survey.
C．Doctors ask for forced coughs.
D．Researchers train the AI model.
【4】What is one of the faults of the research?
A．The limited age range.
B．Failure to evaluate coughs.
C．Inaccuracy of the statistics.
D．Low rate of identifying cases.
23、Governments, financial institutions, employers, border security and police services are increasingly using facial recognition technology. This allows them to quickly confirm an individual's identity. Systems are becoming so competent that a wanted criminal can be picked out. of a crowd of thousands of people. All that's required is an image in a database to compare with the image of any number of people in a crowd.
Ordinary people, too, are using facial recognition to unlock their phones, computers and other devices. Such systems are generally quite secure. They also are instantaneous (瞬间的) and relieve people of the need to memorize passwords or PINs ( Personal Identification Numbers).
Despite these advantages, human rights groups in the U. S. have protested against the growing use of facial recognition technology for two main reasons. The first is that current facial recognition systems frequently make mistakes with certain groups of people. A study conducted by the Massachusetts Institute of Technology examined three systems and found that they wrongly identified up to 34 percent of women who had dark skin. Another government study on facial recognition systems found that their error rates were higher for black women and Asians as well as for African men and women. The systems were much more reliable when they were used to identify white men, suggesting that their facial recognition technology had mainly been trained using white faces.
The second reason is that these systems could be used in ways that would harm human rights. If the systems improved enough to become one hundred percent reliable, police departments might use them to identify people taking part in legal protests and demonstrations. Gathering and storing such information about citizens could violate their privacy rights.
In response to such concerns, the U. S. city of Portland has forbidden the use of facial recognition by government agencies as well as by stores, restaurants and hotels in the city.
【1】What does this article explain about facial recognition technology?
A．What damage it can cause to machines.
B．Why it was surprisingly cheap to develop.

A．They haven't been widely available.
B．They don't save companies money.
C．They can't be tested by scientist.
D．They aren't sufficiently accurate.
【3】What has Portland concluded about the use of facial recognition?
A．It doesn't cause a serious danger to people.
B．It shouldn't be allowed in some businesses.
C．It's helping to keep minority groups safe.
D．It'll boost employment throughout the city.
