21、“Just think positively!”
“It could be worse.”
“You should look at the bright side!”
We’ve all heard (and maybe used) these phrases without much thought. But they could be contributing to a culture of toxic (有毒的) positivity. For those new to this term, it might sound like an oxymoron (矛盾修辞法). How can positivity be toxic? Isn’t it supposed to be helpful, or “positive”, as the name suggests?【1】
“Toxic positivity is when somebody avoids all negative thoughts or feelings, pretending everything is going well when it is not,” explains Melissa Dowd, a therapist at PlushCare, a virtual health platform. Whitney Goodman, another licensed psychotherapist, describes toxic positivity as the “endless pressure to be happy and positive, no matter what the circumstances are.”【2】It’s also something we can cause other people to experience.
Toxic positivity causes us to suppress our emotions, which can make them worse. 【3】“Although it can be helpful to look on the bright side when facing challenges,” Dowd says, “not coping with negative feelings in a healthy way in the moment can lead to those feelings resurfacing later in different areas of your life or as a form of anxiety.” 【4】 “If I feel like you’re going to set me aside, I’m going to stop sharing how I’m feeling,” Goodman adds.
【5】If you’re using toxic positivity against yourself, Goodman suggests remembering it’s OK if you’re upset about something. It’s valid if something annoys you. “Allow ourselves and other people to share when they’re going through a difficult time,” she says. Dowd adds that it’s essential that “we all learn to cope with and process our emotions in a healthy way as opposed to avoiding how we feel” as life’s stressors continue to rise. For example, instead of simply saying “Just think positively,” we’d better say “Sometimes bad things happen. How can I help?”
A．Are there ways to avoid toxic positivity?
B．Toxic positivity also interrupts connection.
C．It can harm people who are going through difficult times.
D．Expressing toxic positivity to others may look like offering them a simple solution.
E．They become more intense and can also cause long-lasting health concerns in the future.
F．Experts say constant forced positivity can lead to the opposite, and have a negative effect.
G．This is what we may bring on to ourselves by not allowing negative thoughts and feelings.
22、 It doesn’t kill germs better than cooler water, but turning tap temperatures high, the US burns carbon equal to the emissions of Barbados.
People typically wash their hands seven times a day in the United States, but they do it at a far higher temperature than is necessary to kill germs, a new study says. The energy waste is equivalent to the fuel use of a small country.
It’s cold and flu season, when many people are concerned about avoiding germs. But forget what you think you know about hand washing, say researchers at Vanderbilt University. Chances are good that how you clean up is not helping you stay healthy; it is helping to make the planet sick.
Amanda R. Carrico, a research assistant professor at the Vanderbilt Institute for Energy and Environment in Tennessee, told National Geographic that hand washing is often “a case where people act in ways that they think are in their best interest, but they in fact have inaccurate beliefs or outdated perceptions.”
Carrico said, “It’s certainly true that heat kills bacteria, but if you were going to use hot water to kill them it would have to be way too hot for you to tolerate.”
She explained that boiling water, 212°F (99.98°C), is sometimes used to kill germs — for example, to clean drinking water that might be polluted with germs. But “hot” water for hand washing is generally within 104°F to 131°F (40°C to 55°C). At the high end of that range, heat could kill some germs, but the sustained contact that would be required would scald the skin.
Carrico said that after a review of the scientific literature, her team found “no evidence that using hot water that a person could stand would have any benefit in killing bacteria.” Even water as cold as 40°F (4.4°C) appeared to reduce bacteria as well as hotter water, if hands were scrubbed, rinsed (冲洗) and dried properly.
In fact, she noted that hot water can often have an unfavorable effect on hygiene. “Warmer water can harm the skin and affect the protective layer on the outside, which can cause it to be less resistant to bacteria,” said Carrico.
Using hot water to wash hands is therefore unnecessary, as well as wasteful, Carrico said, particularly when it comes to the environment. According to her research, people use warm or hot water 64 percent of the time when they wash their hands. Using that number, Carrico’s team calculated a significant impact on the planet.
“Although the choice of water temperature during a single hand wash may appear minor, when multiplied by the nearly 800 billion hand washes performed by Americans each year, this practice results in more than 6 million metric tons of CO2 equivalent emissions annually,” she said.
That’s roughly equal to the emissions of two coal-fired power plants, or 1,250,000 passenger vehicles, over the course of a year. It’s higher than the greenhouse gas emissions of small countries like EI Salvador or Armenia, and is about equivalent to the emissions of Barbados. If all US citizens washed their hands in cooler water, it would be like eliminating the energy-related carbon emissions of 299,700 US homes, or the total annual emissions from the US zinc or lead industries.
The researchers found that close to 70 percent of respondents said they believe that using hot water is more effective than warm, room temperature, or cold water, despite a lack of evidence backing that up, said Carrico. Her study noted research that showed a “strong cognitive (认知的) connection” between water temperature and hygiene in both the United States and Western Europe, compared to other countries, like Japan, where hot water is associated more with comfort than with health.
The researchers published their results in the July 2013 issue of International Journal of Consumer Studies. They recommended washing with water that is at a “comfortable” temperature, which they noted may be warmer in cold months and cooler in hot ones.

23、 As we live longer and technology continues its rapid development, we can imagine a future where machines will enlarge our human abilities and help us make better life choices, from health to wealth. Through our dialogue and digital pieces, AI will understand our life goals and wishes, our duties and limitations. It will help us plan different life events, so we can spend more time enjoying life’s moments.
The ability for artificial intelligence to understand the complexities and slight differences of human conversation is, however, one hurdle. There are several thousand known living languages in the world today. Adding to the difficulties are the varied ways words are shared and used across different cultures, including grammar, levels of education and styles of the speakers. Google Duplex, the technology supporting Google Assistant, which places phone calls using a natural-sounding human voice instead of a robotic one, is an early attempt to address such challenges in human communications. But these are just initial whispers in voice of AI’s long journey.
Beyond making reservations and conducting simple dialogues, virtual assistants will need to become far more useful and further fit into the parts of our everyday lives. Not only will they need to foresee what we need before we ask, they also need to understand the context of our conversations and react accordingly. Imagine a snow day when school is canceled for the kids. Knowing that you must now stay at home with your children, your phone would remind you, asking if you’d like your meetings moved to the following day. Alternatively, imagine how much more pleasant your journey home from a business trip would be if your phone could automatically arrange for a ride waiting to pick you up at the airport, based on your travel plan, location, and habits. The possibilities are endless.
【1】What do we know about AI?
A.They narrow our abilities. B.They limit our better choice.
C.They don’t know our limitations. D.They help us enjoy life better.
【2】What makes it hard for AI to understand what humans say?
A.Low level of speakers. B.Imperfection of AI.
C.Varieties of languages and cultures. D.Similarities between languages.
【3】Which word can best describe the author’s attitude towards AI?
A.Doubtful. B.Approving.
C.Negative. D.Critical.
【4】Which of the following can be the best title of the passage?
A.AI Will Replace Humans
B.AI Will Set Goals for Us.
C.AI Will Be Part of Our Daily Lives.
D.AI Will Meet Challenges.
24、The global population growing, the climate is warming, and, no surprise, the demand for energy is steadily increasing. We need to use less energy in any way that we can.
German design student Tobias Tribenbacher, from the University of the Arts Berlin, has created a street light called Papilio in response to global sustainability initiatives, saying that he initially chose to create a city-facing streetlight due to such lights’ role in tight pollution.
Papilio can be mounted to walls or set up as a freestanding lantern. The lamp should ideally be placed between three to six metres above ground, where ground-level winds are the strongest. The lamp is shaped like a pinwheel that acts as a wind turbine (涡轮), catching the wind to produce its own energy. It also has a rechargeable battery that stores electricity, so the lamp can operated even on less windy days.
Another key component of the lamp is the light itself. The warm- colored light doesn’t draw the attention of insects, and it uses an infrared(红外线的)sensor so that the light is only started by nearby motion, reducing its contribution to light pollution.
Aside from saving public space and beautifying streets, the streetlight’s design is also a visual signal of clean energy in action.“Design not only determines how street lights are working. It can also shape our attitude towards them and consequently affect how we use them,” Tobias Tribenbacher says.“Because energy creation is often an invisible process, projects such as these help the production of electricity become comprehensible.”
The lamp’s ability to change wind power into electricity can also be a huge benefit to naturally windy areas. And since it doesn’t require any electrical infrastructure (基础设施), there will be an opportunity to fix the street lights in remote settings or places where infrastructure innovations can be cost-prohibitive.
Just as lanterns create the character of streets and squares, Papilio is envisioned as a public sustainability statement that motivates residents to take part in transforming our cities into climate-friendly, future-proof environments.
