3 . Turn on a light outside at night, and it won’t be long before lots of insects start gathering around it. This behavior has led to a popular comparison for attraction, “like a moth to a flame.” However, according to a new study published in the journal Nature Communications, it turns out that insects aren’t “attracted” to artificial lights, but rather confused by it.

The new finding is based on a theory about insect orientation (定位). Due to their small and lightweight bodies, insects experience less air resistance, allowing them to achieve higher accelerations (加速度), which in turn makes it challenging for them to sense up and down during flight. So, they typically rely on stable light sources like the moon and stars to orient themselves at night, keeping the sky at their backs to stay upright. However, the introduction of artificial lights confuses their natural sense of direction. The insects you see circling street lights, in other words, are probably lost.

To reach these conclusions, scientists used high-resolution cameras to film insects flying around artificial lights in Costa Rica. They also attached tiny sensors to insects and filmed motion-capture videos of them in flight. In this way, researchers can slow down the insects pace and study their movements in greater detail. The videos showed insects turning their backs toward sources of artificial light — even at the price of flipping over or crashing.

This can be dangerous for insects, as circling around artificial lights can put them at risk from enemies, exhaustion, and starvation, causing many to die before morning. Night artificial light is a major cause of insect population loss, which could severely impact crop pollination and food supplies for larger animals, including humans. “Insects have been flying around for 370 million years, and it’s just in the last 150 years that it’s really gone wrong for them,” says entomologist Samuel Fabian of Imperial College London. “If we don’t want to influence large amounts of insect populations, we should not have lights shining up into the sky.”

4 . Beejhy Barhany, growing up in an Ethiopian-Jewish community in Israel, has been cooking for her family as long as she can remember. Now a chef and owner of Tsion Café in Harlem, New York, Barhany continues to pull from cooking traditions, including one that has become the source of much controversy in recent decades: washing raw meat before cooking.

For Barhany, submerging raw chicken in salt and lemon water is both functional and ceremonial, as soaking or rinsing raw meat in salt water and acid-such as lemon juice or vinegar-is a common form of “washing” required by Jewish Kosher rules. And a 2015 survey of over 1, 500 American consumers found that nearly 70 percent rinse or wash their poultry before cooking it, though the U. S. Department of Agriculture( USDA) started telling consumers not to wash raw poultry in the 1990s. Experts including those from the Centers for Disease Control and Prevention strongly warned that rather than reducing the risk of foodborne illness (食源性疾病), washing meat increases the likelihood of spreading unwanted pathogens (病原体), like salmonella and campylobacter, around the kitchen.

“Washing meat before cooking is not really helping,” says Betty Feng, associate professor of food science at Purdue University. “The only thing it does is splashing (飞溅) and could cross-contaminate a lot of your kitchen items-your sink, probably your clothes, whatever you have by the sink.” Moreover, Feng cautions against using saltwater, vinegar, or lemon juice, which simply isn’t strong enough to effectively kill foodborne pathogens. “If the acidity is high enough to kill bacteria, then it’s not really likely you can use your bare hand to wash,” she says.

And a 2022 study showed that submerging meat in a bowl of water reduced the splashing but not the spread of germs. “I would treat the entire sink just like the outside of the chicken——it’s a biological hazard,” says Benjamin Chapman, one of the study authors and associate professor in North Carolina State University’s agricultural and human sciences department. “The way that we make meat safe is through cooking, not through the removal of pathogens.”

3. What is TRUE about “washing meat before cooking” according to Betty?

A．It has sparked a lot of controversy in recent years.

B．It has decreased the risk of foodborne illness.

C．It can not be directly done/with your bare hands.

D．It may do a favor/ to the transfer of pathogens.

4. Why is the underlined phrase “biological hazard” mentioned in the last paragraph?

6 . Scientists have long believed that Mars was wet around three billion years ago and then lost much of its water. But a new study presents evidence of water activity from about 700 million years ago, posing a new puzzle about Mars and its history for scientists to crack in their future studies.

The new study is based on data from China’s Zhurong rover (“祝融号”火星车), part of the Tianwen-1 mission that touched down on the surface of Mars in May 2021. In particular, the scientists used data the rover gathered during its first 92 Martian days, at its landing site in Utopia Planitia. Yang Liu, a researcher from the Chinese Academy of Sciences(CAS), and his colleagues analyzed data from three different instruments on Zhurong. Those instruments studied minerals that suggest the presence of a large quantity of liquid water at the site about 700 million years ago, which scientists previously thought was dry.

“This is a very interesting result. We have very little recorded evidence of young liquid water systems on Mars. And for the ones we have, they were usually in the form of salt minerals,” says Dr. Scheller, a scientist at the California Institute of Technology. He explained Zhurong’s instruments spotted water molecules locked away in the rock, which was different from other young liquid water environments that have been observed.

“One of the major things we’ll have to find out and that I look forward to seeing from the Zhurong rover is how extensive these ‘young’ water-bearing minerals are,” Dr. Scheller said. “Are they common or uncommon in these ‘young’ rocks?” Zhurong has now covered about two kilometers during its more than 350 Martian days and has analyzed a range of features on its travels, meaning more new Martian insights are likely still to come from the rover.

NASA has so far sent its Mars rovers to ancient landing sites, dating back to more than 3.7 billion years ago. Zhurong is not just an extra set of wheels on Mars, but a powerful suite of instruments exploring a new, geologically young site to open new windows of opportunity for research on Mars.

1. What does the underlined word “crack” in paragraph 1 mean?

A．Keep.

B．Doubt.

C．Solve.

D．Create.

2. What does the new study show according to paragraph 2?

A．The inaccuracy of data gathered on Mars.

B．Functional limitations of instruments on Mars.

C．Main reasons for the failure of the Tianwen-1 mission.

D．The misconception of past thinking about Martian water.

3. Which of the following does Dr. Scheller convey?

A．The result has been recorded by many scientists.

B．Zhurong’s wide analyses will bring more surprises.

C．Salt minerals are younger than water-bear ing minerals.

D．Young water-bearing minerals are common in young rocks.

4. Which word can best describe Zhurong?

A．Ancient.

B．Common.

C．Alarming.

D．Promising.

7 . Steps Towards Unlocking Your Inner Wisdom

At the core of your life lies sense, a powerful force that exists within. Knowing how to follow your sense can help you guide your life.     1    

●Seek loneliness and stillness. In a world filled with noises, finding inner peace requires silencing the noise around you.    2     Try taking a relaxing walk, dipping yourself in nature, deep thinking, or simply enjoying a quiet coffee while observing the world. Engage in activities that calm your soul to achieve a state where your sense flourishes in its full glory.

●Develop self-awareness.     3     Strong intuitive people often spend time on self-examination and spare time for self-awareness training. Instead of running from their emotions, they hug them with openness and acceptance. To follow your inner voice, consider all that lies within. Ask yourself, "What am I feeling right now?" Explore desires, fears or goals that come to light. Take time to sit with your body and run through a full body scan.

●    4     Life is not foretold. Many people struggle to maintain aspects of their lives. Despite inner fear of uncertainty, following your sense may lead you down unfamiliar paths. Welcome this uncertainty with an open heart and an eager spirit. By trusting in its guidance, sense provides priceless help through each stage of life.

●Take action with intention. Once your sense gives guidance, trust yourself enough to act on it on purpose.     5     The idea of gradually progressing to more important, high-pressure decisions increases your ability to deal with discomfort more effectively.

A．Explore the unknown.

B．Stay away from unfamiliar paths.

C．You need to find a place free from any interruption.

D．It is better to think about high-pressure decisions first.

E．Learn how to believe in your sense by making small choices.

F．Raising your sense requires a deep understanding of yourself.

G．And insights gained from your sense can affect everything you do in life.

9 . Insider Flight Tips for Your Journey

Anyone can book a trip, but not everyone can plan an ultimate adventure that is affordable, accommodating and fun. At www. tripinsiders. org, we aim to provide you with the best insider secrets in the travel business. And on this website, we also offer a state-of-the-art travel comparison tool to make planning easier than ever. Here are some insider tips that we'd like to share with you about flights.

Look for Glitch (小故障) Fares

Online booking systems for airfare don’t come without a pricing mistake every once in a while. Follow deal-minded travel sites and blogs to learn about pricing mistakes that work in your favor. This is the most useful if you live near a major airport and have a flexible schedule.

Consider Alternate Airports

Some major cities have more than one airport, so make sure to check them all for the cheapest fares. For example, if you’re planning to visit the Bay Area of California, check for rates in both San Francisco International Airport and Oakland International Airport.

Cross the Border by Land

Domestic flights are often cheaper than international ones, so if you live near a border and want to fly to a neighboring country, you can save by crossing the border by land and then catching a domestic flight. For example, Toronto residents may save by crossing the American border into Buffalo and then flying to another American city.

Use a Digital Luggage Scale

There’s nothing more frustrating than learning that your bag is too heavy to fly or that it’ll cost you extra when you arrive at the airport. Digital luggage scales are great for making sure that you’re not going over the baggage limit with your new souvenirs.
