The minutes leading up to a vacation are often an exciting time. As people check their homes and pack the last items into their suitcases, they often dream about the fun times that lie ahead. In Russia, however, there’s one final step that people take to ensure a good trip. Before they walk out of the door, Russians take a brief pause and silently sit on their suitcases for a few moments.

This unusual tradition started hundreds of years ago. In the years before Christianity, Russians believed that good and evil spirits lived inside their homes. They thought that the key to living a good life was to keep these spirits happy at all costs. If a person rushed out of their home before a trip, there was a good chance that they would forget something. When that person returned a few minutes later to get it, they would disturb the evil spirits in the home. In response, the spirits might follow them out of the door and accompany them on their trip. Since the spirits were offended by the person, they would bring them bad luck and possibly cause them harm.

Although many years have passed since suitcase sitting began, the practice continues to this day. As the Soviet Empire grew during the Cold War, suitcase sitting even spread throughout Eastern Europe. Although it’s rooted in superstition (迷信), suitcase sitting is actually quite practical. It can prevent people from forgetting passports, plane tickets, or keys. In addition, it also provides a brief moment of relaxation that can help get a journey started on the right foot. Besides that, if someone has packed too many clothes, suitcase sitting can help get it zipped up.

1. What is this passage mainly about?
A.A spirit that haunts anyone who attacks Russia.
B.A popular vacation spot in ancient Russia.
C.An old tradition that is based on scientific research.
D.A habit meant to bring good luck to travelers.
2. According to the passage, why do people sit on suitcases?
A.To keep spirits from following them on journeys.
B.To test the strength of their suitcases.
C.To invite good spirits to come on vacation.
D.To ask spirits to protect their homes.
3. What is NOT true about suitcase sitting?
A.It was made illegal during the Cold War.
B.It is practiced outside of Russia as well.
C.It started in Russia many years ago.
D.It is not based on Christian ideas.
4. What does the writer imply about suitcase sitting at the end?
A.It’s an old practice that should be forgotten.
B.It is no longer necessary in the digital age.
C.It often makes people stressed out before an important trip.
D.It has benefits that everyone can experience.

文章大意:本文是一篇说明文。主要讲述了独处时间对心理健康的重要性。

【推荐1】How Important Is Alone Time for Mental Health?

People tend to be social creatures, and research has shown that social connections are vital for both emotional and physical well-being.     1     The COVID-19 pandemic demonstrated both the challenges of loneliness and a lack of alone time. Having time for yourself gives you the chance to break free from social pressures and tap into your own thoughts, feelings, and experiences. Why is it important to be alone?


Creativity

    2     Research actually suggests that being alone can lead to changes in the brain that help fuel the creative process.

In a 2020 study published in the journal Nature Communications, researchers found that perceived social isolation (loneliness) led to increased activity in the neural circuits related to imagination. When left with a lack of social stimulation, the brain increases its creative networks to help fill the blank.


Social Energy

    3     However, researchers have found that people who live alone may actually have richer social lives and more social energy than people who don’t.

Sociologist Eric Klineberg notes that one in seven U.S. adults lives alone. Klineberg found that not only were these adults not lonely, many actually had richer social lives.


How to spend time alone?

Pick a time: Figure out when you’d like to spend some time alone. Plan that time into your schedule and make sure that other people know that they shouldn’t interrupt you during that time.

    4     : Work on removing distractions, particularly ones that invite social comparisons. Your focus should be on your own thoughts and interests and not on what other people are doing.

Plan something: Not everyone is comfortable spending time alone, so you might find it helpful to plan out what you want to do.     5    

There’s no correct amount of solo time that works for everyone. Think about things that you might like to do by yourself, then start practicing doing them alone.

A.Turn off social media.
B.Focus on others’ behavior.
C.Living alone tends to be seen in a negative light.
D.Solo time is an opportunity to strengthen your creativity.
E.However, alone time also plays a crucial role in mental health.
F.Therefore, there are things you can do to boost social connections.
G.This might involve relaxation time, exploring favorite hobbies,or reading books.

【推荐2】Spider webs are made from silk. And silk is made from something scientists call “proteins”. Proteins are special chemicals made by a living thing like an animal or a plant. You have lots of them in your body. Your hair and your nails are made of proteins (they are both made by a protein called “keratin”). Insects and spiders make silk in a special part of their bodies called a gland (腺), and use their legs to pull it out of their bodies. This is called spinning. Most species of spider have more than one kind of silk gland. Each one has different strength and stretchiness and is used for a specific purpose such as web frame, or covering eggs. The strength and stretchiness of silk depends on the way the spider’s body arranges the silk proteins.

We don’t usually notice just how strong they can be because they are amazingly thin. But the strongest silk, such as silk from a golden orb spider, is actually stronger than steel. Even more amazing, it is about 50 times as light. Actually, spider silk is a bit like a cross between steel and rubber. Even with the help of complicated machines and chemicals, humans still don’t know how to make a material this strong, stretchy, and light. Spiders are still the champions at this.

In fact, silk-making animals include crickets, glow-worms, ants, bees, etc. Some of these make silk to protect themselves. Crickets, for example, use silk to sew leaves together to build a nest. Some use silk for hunting, such as spiders and even glow-worms, which use sticky silk to capture flying animals they’d like to eat.

Studies about spider webs could pave the way for creating new materials that could be used in medicine and engineering. But synthetic (人工合成的) spider silk has been difficult to create. In the meantime, researchers hope their work will help us unreel one of the toughest materials of the natural world.

1. What can we learn from paragraph 1?
A.Insects and spiders’ legs can make silk.
B.Spider webs are made of keratin.
C.All species of spiders have a variety of silk glands.
D.Arrangements of proteins determine silk features.
2. Why is steel mentioned in paragraph 2?
A.To stress the strength of spider silk.B.To describe the advantages of spiders.
C.To compare the two materials.D.To highlight spiders’ advantages over people.
3. Which of the following can replace the underlined word in paragraph 4?
A.Remove.B.Explore.C.Test.D.Replace.
4. What is the writing purpose of the passage?
A.To raise awareness of the research on insects.B.To explain the knowledge about spider silk.
C.To encourage us to focus more on the spiders.D.To present the application of spider silk.

【推荐3】In July, 2015, NASA's Kepler mission has confirmed the first near-Earth-size planet in the "habitable zone" around a sun-like star. This discovery and the introduction of 11other new small habitable zone candidate planets mark another milestone in the journey to finding another "Earth"

The newly discovered Kepler-452b is the smallest planet to date discovered orbiting in the habitable zone—the area around à star where liquid water could pool on the surface of an orbiting planet—of a G2-type star, like our sun. The confirmation of Kepler-452b brings the total number of confirmed planets to 1,030.

"On the 20th anniversary year of the discovery that proved other suns' host planets the Kepler has discovered a planet and star which most closely resemble the Earth and our Sun," said John Grunsfeld, associate administrator of NASA's Science Mission Directorate in Washington. “This exciting result brings us one step closer to finding an Earth 2.0.”

Kepler-452b is 60 percent larger in diameter than Earth arid is considered a super-Earth-size planet. While its mass and composition are not yet determined, previous research suggests that planets the size of Kepler-452b have-a good chance of being rocky.

While Kepler-452b is larger than Earth, ' its 385-day orbit is only 5 percent longer. The planet is 5 percent farther from its parent star Kepler-452 than the earth is from the sun. Kepler-452 is 6 billion years old, 1.5 billion years older than our sun, has the same temperature, and is 20 percent brighter and has a diameter 10 percent larger.

"We can think of Kepler-452b as an older, bigger cousin to Earth, providing an opportunity to understand and reflect upon Earth's evolving environment," said Jon Jenkins, who led the team that discovered Kepler-452b. "If all the necessary ingredients and conditions for life should exist on this planet, there would be a good opportunity for life to arise."

To help confirm the finding and better determine the properties of the Kepler-452 system, the 'team conducted a series of ground-based observations: These measurements were the key for the researchers to confirm the planetary nature of Kepler-452b and to better pin down(确定)the size of the planet and its orbit.

1. When was the first host planet found in another solar system?
A.In 2015.B.In 1985.

D.Kepler-452b is a planet orbiting in the habitable zone.
3. Scientists have conducted a series of ground-based observations to find out _____________.
A.which Kepler-452b resembles more, the earth or the sun
B.more mysteries in our solar system
C.the planetary nature of Kepler-452b
D.the significance of NASA's Kepler mission
4. The passage is mainly about_________________.
