When we are children, the holidays seem to last forever. But later, we may find that the time just seems to fly by. Why does time seem to pass faster as we get older?
According to the Daily Mail, our brainsdegradeas we get older. That decreases the amount of information we can deal with in a single day. “The human mind senses time changing when the perceived (被感知的) images change,” Adrian Bejan from Duke University, US, told the Daily Mail. “The present is different from the past because the mental viewing has changed, not because somebody’s clock rings.”
Infants (幼儿), for example, move their eyes much more often than adults because they’re processing (处理) images at a faster rate. They deal with a large amount of information and do many things in a single day. This makes them feel like a single day lasts for a long time. However, as people get older, fewer images are processed in the same amount of time. Therefore, older people receive less information during a day than younger people. This causes things to seem as though they’re happening more quickly.
Apart from the degradation of our brains, some psychological reasons also make us experience time differently.
People may measure time by the number of memorable events that can be recalled (回忆) within a certain period. When we think about our youth, we may remember a life packed with first—time activities, for example, our first time traveling without our parents, or our first date. We experienced these events so vividly that time then seems to us to have passed very slowly. According to David Eagleman of the Baylor College of Medicine in the US, recalling these memories makes us feel like they took forever.
Many adults find life is routine and sometimes dull. For this reason, when they look back, they might feel like there are not many exciting things to remember. Therefore, time seems to be moving faster to them.

【推荐2】Phones are more important than ever in the daily lives of students, but how they use them has changed greatly in the past six years.
Teachers from London University surveyed 1,055 young people aged 13 to 18 about their mobile phone habits. Students use mobile phones mainly for two reasons: “communication” or “entertainment”. Communication means talking on the phone, sending text messages (发信息) or chatting using the software (软件) like QQ or WeChat. Entertainment was made up of playing games, watching movies, listening to music and surfing the Internet. The findings are different from the study of 2016. The results are below:
①talking ②sending text messages ③chatting ④playing games ⑤watching movies ⑥listening to music ⑦surfing the Internet |
Six years ago, students spent around 36% of their mobile phone time making or answering calls. In 2022, only 10% of the time was used for talking. When students use their phones to communicate, they’d like to use QQ or WeChat.
“Communication is still an important use of mobile phones. But now mobile phones are being used more for entertainment than for communication,” said Dr. Harry Lectre.
1. What is the least popular mobile phone activity in 2022?A.Talking. | B.Playing games. |

Most people have a place to call home on Earth. What about in outer space?
“You just have this impression that we’re all citizens of not a country, but of the planet,” former NASA astronaut Scott Kelly told National Geographic about working in the ISS.
Over the past 22 years, the ISS has mainly been used as a science lab, hosting 241 people from 19 countries, according to NASA. They went on spacewalks, did research on how space affects the human body, and even grew plants in space.
However, after being our home in space for over 7,000 days, the station is starting to get old. It has leaked(漏出) air a few times.
In the future, space will be home to more stations like the ISS. NASA is building a space station that is smaller than the ISS near the moon.
A.Scientists think that the station can keep working until 2024. |
B.Also, China will have its own space station up and running by the end of 2022. |
C.The International Space Station(ISS) became our first “home” in space in 2000. |

The energy value of food is usually measured in calories (卡路里). A calorie is the amount of heat which is required to raise the temperature of 1kg of water by 1℃. The number of calories people need per day is different, as the form below shows. Also, the number of calories you use at any one moment normally depends on the activity you are in. For example, you need more calories for standing than for sitting, more for running than for walking, and so on.
The energy in food is in the form of three kinds of chemical materials-carbohydrate (碳水化合物), protein (蛋白质) and fat. Carbohydrate provides 3.8cal/gm of the energy, protein 4.0cal/gm, and fat 8.8cal/gm. Each food has different amounts of these materials, as the round pictures show.

【推荐2】Most people who move to a foreign country may experience a period of time when they feel very homesick and have a lot of stress. This feeling is often called “culture shock.” It is important to understand it and learn how to deal with it if you want to adapt successfully to your new home’s culture.
Generally speaking, there are four stages that you will experience after you move to a foreign country. The first stage is usually referred to as the “excitement” stage. When arriving in a new environment, you’ll be interested in the new culture; everything will seem exciting and everyone will seem friendly.
But it won’t be long before you move from the “excitement” stage to the second stage. The excitement you felt before changes to stress. It seems that everything is difficult. The language is hard to learn, friends are difficult to make, and even simple things like shopping have become a challenge. It is at this “stress” stage that you are likely to feel worried and homesick. This is the stage which is referred to as “culture shock.”
However, culture shock doesn’t last for very long. If you are one of those who manage to overcome it, you’ll move to the “recovery” stage. At this stage, you start to understand and accept the way things are done and the way people behave in your new environment.
The last stage is the “home” stage. This is the stage when you start to feel at home in the new culture. You start to learn from your new home and to like certain aspects of the new culture better than those of your own culture.
Culture shock is normal. Everyone in a new situation will go through some form of it. Continue to be brave! And overcoming culture shock will be a piece of cake.

Are you having a hard time staying focused on work? Some simple skills can make a big difference. | ||
1. Take care of your physical needs. The most basic one for focusing is to take good care of yourself. This means getting regular exercise. Beyond that, make sure you’re getting good nutrition which supports your brain’s work. Most of all, get plenty of sleep. When you’re tired, it’s much harder to focus on anything. | ||
2. Plan for your “absent-minded behaviours.” You may try to do something to reduce the stress coming from a task. These things, like mindless snacking, checking email, checking phone texts, or suddenly getting very sleepy, may also make you absent-minded. So, if you want to get focused, plan for these behaviours. If you are likely to get sleepy, try moving to a standing desk for a while. Prepare a healthy snack to keep by your desk. If you can’t help reading email or checking your mobile phone, turn off the notices which are flashing and reminding you all the time. | ||
3. Plan regular breaks. One popular way is the Pomodoro Technique, which calls for 25 minutes of focused work followed by a 5-minute break, with at least a 15-minute break every two hours. Recently, a new experiment shows that it is best for you to take a 17-minute break after working for 52 minutes. | ||
4. Accept yourself for losing focus. It is true that you won’t always meet your own expectations of focus. Getting angry or upset about it will only make things worse. Instead, praise yourself for whatever work you manage to get done. And being happier may help you succeed. |
A.Having different snacks. | B.Using a standing desk. |
C.Getting regular exercises. | D.Turning off the phone. |
A.You can stay fully focused if you follow the rule of it. |
B.You must take a 25-minute break after working for 60 minutes. |

It made the perfect place for him to study and get to know the nature. He had seen some red-tail hawks, red foxes, wood turtles and other animals. He also found special native flowers.
Suddenly it was announced that the “empty” land would be improved by a lot of houses on it. The plants would be removed, the animals would run away and most would probably die. Then the wet soil would be covered with extra grounds.
When he heard about the news, he was not happy. He was very worried that the land ans water would be polluted.
Andrew wrote down clearly all the research he had down about the area, and how the houses would affect the local environment. He sent letters to members of local government and television reporters. He also called on his neighbors to oppose the building of the houses.
Although he was only 12 years old, he had the courage and wisdom of a person much older. Andrew’ s teachers described him as gentle, shy and active. His classmates also admired how much he knew about local animals and plants,and the environment.Each day after school, Andrew went door-to-door, to ask the people to sign, who did not want the houses to be built. In only one month, he got the signatures of 250 people.
In the end, the land remained a safe place for birds, animals and plants that belonged there.
Andrew won many prizes for his brave and great work to stop the houses being built,and thus help save the environment.

You may know a lot about smartphones. But what about smart cities?
Imagine living your life like this: When you wake up in the morning, you say "Open the window" to the computer and it opens the window. The sunshine is shining and the birds are singing. Then you finish breakfast and sit in front of your desk and begin to have classes through the Internet. With the help of building a smart city, this may become true one day.
A smart city uses digital technologies(数字科技)such as the Internet to improve city planning, save resources(资源) and make our lives easier. For example, people live in smart cities, where there is Internet almost everywhere. They can do many things at home, such as booking train tickets, paying water bills and shopping online. What a convenient life it is!
Now China is making some cities smarter. For example, Guiyang is going to build free Wi-Fi in the whole city. Tianjin plans to start a smart city program to solve traffic problems. Guangzhou is creating a smart city, so everyone in the city should play a role in creating a smart city.
1. Which city is planning to start a smart city program to solve traffic problems?A.Guiyang | B.Tianjin | C.Guangzhou | D.Beijing |

Everybody’s house smells in some way.
You almost never even notice the way your own place smells. You notice the way everyone else’s place smells as soon as you walk in. There are their cats, and the soap, and the new furniture they just got. And those all add up to the way their house smells.
But you can only smell your own house after you’ve been away for a while—like, a long while. Not just a workday, but like a week.
It has to do with sensory adaptation (感觉适应). That’s the scientific way to say that you just get used to it. And it’s more pronounced for our sense of smell than for any other sense, like our hearing, for example.
Researcher Pamela Dalton at the Monell Chemical Senses Center has done a lot of work on sensory adaptation. She and her team say that adaptation means you respond (做出反应) less when a stimulus (刺激物) is repeated. So when you’re at home, the smell of your house is all around you. It never goes away. It’s not just repeated—you’re swimming in it. So you become adapted to the way it smells.
The thing with smell, though, is that you adapt to smells really quickly. After “even a few breaths” of a smell, Dalton says, you begin to acclimate to it.
You start to experience that smell as being less strong and finally take no note of it at all. That’s why you can smell your friend’s house when you walk in, but you don’t really notice it all the time you’re there.
Being able to detect (探测) smells is important. It might warn you of danger, like an approaching (接近的) tiger or something gone bad in your drinks. Or it might mean something pleasant, like that fresh bread or the blooming flowers.
Your nose can stay on the lookout for new smells that are dangerous or delicious.
It might be a simple housekeeping thing, like a dishwasher in the kitchen or towels in the bathroom that needs to be cleaned .
Then, if you still want to change the way your house smells, many things might do the trick, like a million candles, fresh fruits, or a bottle of perfume.
1. From Paragraph 2 we know our _______ may not be part of our house smells.A.cats | B.soap | C.new sofa | D.old chairs |
A.when a stimulus is repeated, people respond more. |
B.when you’re at home, the smell of your house never goes away. |
C.You don’t really smell your friend’s house all the time you’re there. |

In China, although teenagers can get their ID cards at 16, many only see themselves as an adult when they are 18. In the US, where everyone drives, the main step to the freedom of adult life is learning to drive. At 16, American teens take their driving test. When they have their license(证), they drive into the grown-up world.
"Nobody wants to ride the cheese bus to school," said Eleanor Fulham, 17. "It's like you're not cool if you don't have a car," she said.
According to a recent research, 41% of 16 to 19 year olds in the US own cars, up from 23% in 1985. Although, most of these cars are bought by parents, some teens get part-time jobs to help pay.
Not all families can afford cars for their children. In cities with undergrounds and limited(有限的) parking, some teenagers don't want them. But in rich areas outside the city, if there are no undergrounds, and bicycles are more for fun than cars, it is strange for a teenager not to have a car.
But police say 16-year-olds have almost three times more accidents than 18 and 19-year-olds. This has made many parents stop before letting their kids drive. They need to wait until they are more experienced.
Julie Susiana, of Virginia, decided that her son Chad, 15, will wait until he is 17 to apply for his learner's permit (许可)
Chad said he has accepted his parents' decision, although it has caused some laughing from his friends. "They say that I am unlucky," he said. "But I'd rather be alive than driving, and I don't really trust my friends on the road either."
In China as more families get cars, more 18-year-olds learn to drive. Will this become a big step to becoming an adult?

A.they want to show themselves off |

How wrong I was! The misunderstanding began at the airport. I was looking for a public telephone to tell my American friend Danny that I had arrived. A friendly old man saw me looking lost and asked if he could help me.
“Yes,” I said, “I want to give my friend a ring.”
“Well, that’s nice,” he said, “Are you getting married? But aren’t you too young?”
“Who is talking about marriage?” I replied, “I only want to give my friend a ring to tell him I’ve arrived. Can you tell me where there is a phone box?”
“Oh,” he said, “there is a phone downstairs.”
When at last we met, Danny explained the misunderstanding to me.
“Don’t worry,” he said to me, “I had so many difficulties at first. There are lots of words which Americans use differently in meaning from British people. You’ll soon get used to all the funny things they say. Most of the time, British and American people understand each other.”
