4 . For those in search of safe, non-medicine sleep aids (助手), sound machines are a popular choice. The National Sleep Foundation recently found that 5% of Americans sleep with a “sound conditioner”. It can be a fan, phone app, or other noise-producing machines.

Michael Grandner, director of the Sleep and Health Research Program at the University of Arizona, says a sound conditioner is a lifesaver if you live where loud nighttime noise is common. But even if your bedroom is very quiet, sound machines can still be helpful if you’re the type of person unsettled by a total absence of noise, or if you’re a light sleeper who wakes from even the softest sound.

Research supports the idea that a little background sound can help people fall asleep. For a study in the journal Sleep Medicine, the researchers asked sleepers to listen to recorded hospital sounds either with or without a white noise machine. They found that those who slept with the white noise machine were hardly affected by the hospital sounds, while others who slept without white noise were easily awakened.

There’s also so-called “pink noise” and “brown noise”, which can sound similar to white noise. “I don’t think there’s enough evidence yet to say one type is better than another,” says Michelle Drerup, a sleep psychologist at the Cleveland Clinic. “I know from talking with my patients that some people prefer natural sounds, like a rainstorm. But others don’t want a sound at all when they sleep,” she says. “It all comes down to the individual (个人).”

For some, the best sound might be none. “Biologically (生物学上), you don’t need this sound to sleep,” says Michael Grandner, “and if you use it every night, you can get so used to it that you can’t sleep without it.” Most sleep experts agree. “I wouldn’t suggest people use sound machines to sleep unless they’re reporting difficulties with outside noises,” an expert says.

5 . For the past 10 years I have been cycling on the Qinghai-Tibet Plateau. Every summer vacation, I spend a month biking across the plateau.

In 2014, I set out on a cycle route with five other people in the far west of the Tibet autonomous region. Our 2,000-kilometer route started in Lhasa in the east, passed through the northern part of the prefecture (辖区) and ended in the west.

Titled the “top of the Roof of the World”, the plateau, which has a small population, has incredible scenery. Travelers can see the snowy mountains, clean blue lakes, lots of animals during the day, and clear, starry skies at night.

The route consists of dirt, even broken stones and paths, which have been formed over time by passing vehicles. Animal attacks are a potential risk in the wild. One night, we had to camp near a forest where there were potential animal attacks, especially from wolves. We found a house in a locked yard, but no one answered our calls from the gate. It was the time of the seasonal migration, so maybe the people had moved to another place for better water and grass. Then we had to camp outside. One of us was very experienced and careful. He placed some hay bales (干草捆) alongside the wall and said that if something dangerous happened, we could use them to jump into the yard and shelter (躲避) in the house.

Luckily, we didn’t meet any wolves or other animals, though we could hear them calling. Animal attacks remain a major cause of injuries on that route. Before the trip, we read online that a traveler had been bitten by wolves. The temporary “step” our companion built made us feel safer.

Once upon a time there were two boys living in a palace,     1     job was serving the King. And one boy liked a girl so much that he wanted to give her a present.

One day, he saw a big vase filled with     2     loveliest flowers. He decided to take one to the girl every day, with the thought that no one would see him do so. But one day, the King noticed how few flowers     3     (leave) in the vase and was so angry that he commanded (命令) everyone in the palace to come to the hall.

Before they all arrived, the other boy told the boy     4     (be) quiet, because the King would be     5     (terrible) angry with him. The boy was     6     (frighten) with fear, but when the King came near, he decided to tell the     7     (true).

As soon as the boy admitted having taken the flowers, the King went red with anger, but after     8     (hear) what the boy had done with the flowers, the King said     9     a smile, “I couldn’t have thought of a better use for my flowers.” Then from that day, the boy became one of the King’s most     10     (depend) friends.

9 . Gossip is the sharing of personal information about someone else who is not present. All of us have probably caught ourselves, from time to time, allowing ourselves to enjoy the pleasure of gossiping more than we would like to admit. Someone says the words, “Don’t tell this to anyone.”     1     We all know that we shouldn’t talk behind someone’s back, but gossip is so common.

Gossip has some characteristics (特点). First, gossip is an activity that is done with other people.     2     Second, the information shared is always about someone who is not present in the conversation, or about someone whom we believe to be absent. Third, when we gossip, we not only share facts, but also make some judgments about the person.

Researchers studied volunteers, including women and men, to find out some facts about gossip. They found that most gossip was neutral (不偏袒的).     3     Most of this gossip was about people they knew of. Negative gossip was twice as common as positive gossip. Over three-fourths of the gossip was simply discussing someone else.

    4     Outgoing people gossip more than quiet people. People who are wealthier and well-educated gossip more than people who have less money and education.     5     On average, people spent about 52 minutes a day gossiping. The study showed that gossip is everywhere.
