Whether we admit it or not, many of us have experienced loneliness. Last month, a survey done by US health service company Cigna found that loneliness has become a common situation in the country. It even found that young people aged 18-22 are more likely to feel lonely than the elders. Loneliness often leads to the emotions of sadness and loss, and can even “make us sick”. So, how do we deal with the pain of loneliness?

Throwing ourselves into distractions can be useful. US lifestyle writer Adrienne Breaux wrote about how she turned loneliness into a productive learning process. She used to be a terrible cook, but whenever loneliness hit her, she would buy a lot of ingredients and try out how to make them into delicious dishes. After a few months, she became good at cooking dishes she’d never even made before.

This is a typical example of how loneliness gets us out of our comfort zone and allows us to grow. “When it comes to keeping loneliness at bay (控制住) , one of the best ways is to occupy your time with things that feel enriching, creative and exciting.” Breaux wrote, “It’s hard to feel lonely when you’re trying to master a new skill, practice a hobby or try out a new recipe.”

The attitude we choose toward loneliness is also the key to deal with it. If we see loneliness as an unwanted and annoying thing, we will suffer it. But if we admit that it’s an everyday part of life, we’ll be able to “embrace (拥抱) the beauty of our solo journey”, as best-selling US author Mandy Hale wrote in her book The Single Woman.

Instead of desperately (拼命地) finding someone to talk to or go out with, trying to have fun on our own is more practical. US Internet writer Kayla Albert shared a story of her friend, who uses her time alone to do what she really wants to do. Her friend goes out for dinner, watches movies, and visits art museums — all on her own. She claims that this kind of single lifestyle brings her joyfulness and gracefulness.

So, we can do it too. Indeed, sometimes, the best songs are the ones performed alone.

1.The survey from Cigna in Paragraph 1 tells _______.

A.when people might experience loneliness

B.how common the problem of loneliness is

C.how people deal with the pain from loneliness

D.what kind of people might suffer from loneliness

2.What was Adrienne Breaux’s solution when loneliness hit her?

A.To keep herself in the comfort zone.

B.To get a new job being a good cook.

C.To spend time for self-improvement.

D.To relax by writing her lonely feeling.

3.What can we learn from the passage?

A.Going out with friends is better than staying alone.

B.The key to solve loneliness is to accept and enjoy it.

C.The pain of loneliness gets worse as people get older.

D.Seeing loneliness as an unwanted thing helps us avoid it.

Have you ever experienced the feeling of falling as you start to fall asleep? Sometimes you may come to realize this feeling. If so, don’t worry. Many people have felt the same thing.

In fact, these muscle twitches (肌肉抽搐) in the arms, legs or other parts of the body are called hypnic jerks (入睡抽动) or sleep starts. And they are very common. Up to 70 percent of people experience them sometimes, Huffington Post reported. But what causes it?

There are some theories(理论). Some scientists believe that the feeling of falling comes from the body relaxing itself, especially if the person is anxious or unable to get comfortable. As you’re about to sleep, your muscles become relaxed. But your brain stays awake. It misunderstands the relaxing of your muscles as a sign that you’re falling.

Then the brain jerks the body awake as if it’s trying to protect you.

Other scientists believe that different phases of sleep might cause the hypnic jerks. When we sleep, we experience two phases: non-rapid eye movement (NREM) and rapid eye movement (REM). During REM, our heart rate (心率), breathing and nervous system can act irregularly (不规律地). If the body experiences flashes (一瞬间) of REM while entering sleep, these irregularities could cause twitches.

If you don’t want to experience hypnic jerks, scientists have some suggestions. When you become deeply relaxed, you can learn how to reconnect slowly by moving your fingers and toes a little bit. Then start to move your head and open your eyes, while being aware of yourself as you get out of the relaxed state.

But experts agree that hypnic jerks, though sometimes scary, are harmless. If it wakes you up, simply roll over and go back to sleep. But keep in mind: a caffeinated (含咖啡因的) drink, exciting evening activities or stress may make hypnic jerks happen more often.

1.The third paragraph mainly tells us_____________.

A. there are all kinds of theories about hypnic jerks

B. different phases of sleep might cause hypnic jerks

C. People sometimes get anxious or uncomfortable

D. the feeling of falling comes from the body relaxing itself

2.How many theories on what causes hypnic jerks are mentioned?

A. Two　　 B. Four　　 C. Three　　 D. Five

3.Which of the following can make hypnic jerks happen more often?

(1)Drinking caffeinated drink　　　　　　　　 (2)Singing songs for a long time before sleep

(3)Too much stress　　　　　　　　　　　　　 (4) reading a book quietly

A. (1)(2)(3)　　 B. (1)(2)(4)　　 C. (2)(3)(4)　　 D. (1)(3) (4)

4.What is the best title?

A. How to Experience Hypnic Jerks　　 B. What causes Hypnic Jerks

C. Feelings of Falling While Going to Sleep　　 D. Sleeping Is Good for Our Health
