You have waited 45 minutes for the valuable 10 minutes’ break between classes. But when the bell for the next class rings, you can’t how quickly time has passed.
If you are familiar with this , you’ll know how time flies when you are having fun and when you are bored. Now scientists have a reason why this is the case.
Scans have shown that patterns of activity in the brain according to how we focus on a task. When we are , we concentrate more on how time is passing. And this makes our brains the clock is ticking more slowly.
In an experiment by a French laboratory, 12 volunteers watched an image researchers monitored their brain activity.
The volunteers were told to concentrate on how long an image appeared for, then the color of the image, and thirdly, study both duration and color. The results showed that was more active when the volunteers paid subjects.
It is thought that if the brain is focusing on many aspects of a task, it has to its resources, and pays less attention to the clock. , time passes without us really it, and seems to go quickly. If the brain is not so active, it concentrates its energies on monitoring the passing of time. , time seems to drag.
Next time you feel bored , perhaps you should pay more attention to what the teacher is saying!

China is known as a country of etiquette (礼节) and ceremonies. Here is an interesting story that shows this. Once upon a time, a man 36 on a long trip to visit his friend and took a swan as a gift.

When his friend received this 41 gift, he was deeply moved. And the 42 ‘The gift is nothing much, but it’s the thought that counts.’ was 43 far and wide.
Chinese used to 44 one hand in the other in front of the chest as a salute. This 45 has a history of more than 2,000 years but nowadays it is 46 used except on the Spring Festival. And shaking hands is more popular and 47 on formal occasions. Bowing was often used by people in a 48 position such as subordinates(下属), students, and attendants. 49 at present Chinese youngsters tend to simply nod as a greeting.
It is common social practice to 50 the junior to the senior, or the familiar to the unfamiliar. When you start a talk 51 a stranger, topics such as weather, food, or 52 are a good choice to break the ice.

Suddenly, we heard a 36 and saw a man dashing out of a lift. Just as he ran 37 us, we saw an old woman coming out of the same lift and crying, “Thief!

No one would be willing to pay one-third of the price for the packaging or wrapping of what he or she purchases. But over-packaging has become a disease that leads to an __50__ waste of resources and __51__ environmental pollution.
The wasted packaging materials are __52__ to be worth about 280 billion yuan annually. And such packages and wrappings thrown away by customers __53__ up half of the volume of solid waste in cities. __54__, it is high time that regulations were __55__ to stop enterprises from spending too much on unnecessary packaging and wrapping.
To produce paper packaging or wrapping, many more trees have to be cut down. Over-packaging also limits the interest of consumers when they have to spend quite a high percentage on something that they will have to throw into the dustbin. The simple truth is that the more a producer spends on packaging, the __56__ the products it sells will be.
Product packaging and wrapping used to be very simple 30 years ago. "Shabby" was the word many had used to __57__ the way Chinese products were packaged. And shabby packaging was blamed for making Chinese products __58__ in the international market.
It is __59__ to pay enough attention to packaging or wrapping products in such a manner that they can be __60__ to customers' eyes. But that does not definitely justify that packaging should even outshine what is inside.
In the Chinese proverb, “maidu huanzhu,” the buyer returns the pearl and just keeps the case because the __61__ is too fancy and luxurious. It not only laughs at the poor __62__ of the buyer, but also criticizes the unnecessary __63__ the seller has made in making the case. Another message from the proverb is that over-packaging helps cultivate an __64__ consuming attitude - to buy fancy-looking stuff but not what they really need.

Job stress has been known to cause heart problems in people who already have cardiovascular(心血管) disease. Now Finnish scientists have shown that 50 in healthy people the pressure of work can cause damage.
High blood pressure, lack of 51 , smoking and being overweight 52 to heart disease—a 53 killer in many industrialized countries.
But Mika Kivimaki, of the Finnish Institute of Occupational Health, and his colleagues, who studied the 54 histories of 812 healthy Finnish men and women in a metal industry company over 25 years, said job stress also plays an important role.
Workers who had the highest job-related stress levels at the start of the study were more than twice as 55 to die of heart disease, 56 the study published in The British Medical Journal.
Work stress 57 too much work as well as a lack of satisfaction and feeling undervalued and 58 .
Many people work long hours but if the effort is 59 the stress is minimized. Kivimaki said job pressure is damaging when being overworked is 60 with little or no control, unfair supervision and few career opportunities.
The British Heart Foundation said the results 61 earlier research showing that people in jobs with low control, such as manual workers, could be at greater 62 of heart disease than other employees.
“It is 63 for people to try to minimize levels of stress at work and for employers to 64 people to have more control at work and to be rewarded for their success,” the foundation said in a statement.
