Physical activity is known to reduce the risk of some diseases such as heart disease, stroke and diabetes. It is also known to increase the release of endorphins(安多芬)which reduce feelings of pain and help people feel more happy and peaceful. Some experts believe it is the act of exercising itself. Others say it is the feeling one gets from having met an exercise goal. Either way, the two things work together when it comes to improving one’s emotional health.
Aerobic exercise gets out heart rate going faster and increases our breathing. Activities like walking at an increased speed, dancing, swimming or riding a bicycle are good examples. Muscle-strengthening activities help build and strengthen muscle groups in the body.
Experts sat adults should get at least two and a half hours of aerobic exercise each week. Mote intense activities reduce the suggested amount of time to one hour and fifteen minutes.
Earlier advice from the Centers for Disease Control said people need to exercise thirty minutes each day for at least five days to get the health benefits of exercise. More recent research suggested that those gains are the same whether you exercise for short periods over five days or longer sessions over two or three days. They help people guarantee that they stay with the program.

To extinguish （熄灭） different kinds of fires, several types of fire extinguishers have
been invented. 1____. Most portable kinds operate for less than a minute,
so they are useful only on small fires. The law requires ships, trains, buses and planes to carry
extinguishers.
Since fuel, oxygen and heat must be present in order for fire to exist, one or more of these things must be removed or reduced to extinguish a fire. 2_____. The cooling method is the most common way to put out a fire. Water is the best cooling material because it is low in cost and easy to get.
____3____. This is usually done by covering the fire with sand, steam or some other things. A blanket may be used do cover a small fire.
A third method is called separation. _____4______.
The method that is used to put out a fire depends upon the type of fire. Fires have been grouped in three classes. ____5____. These materials usually help keep the fire on. Such fires can be stopped most readily by cooling with water.
| A．Fire extinguishers should be available everywhere in our life. |
| B．They must be ready for immediate use when fire breaks out. |
| C．Where a fire breaks out, there will surely be unavoidable damage. |
| D．Fires in wood, paper, cloth and the like are called Class A fires. |
E. Another method of extinguishing fire is by cutting off the oxygen.
F. If the heat is reduced by cooling the material below a certain temperature, the fire goes out.
G. It includes removing the fuel, or material easy to burn, from a fire, so that it can find no fuel.

People from East Asia tend to have more difficulty than those from Europe in 42facial expressions – and a new report published online in Current Biology explains why.
Rachael Jack, University of Glasgow researcher, said that rather than scanning evenly (均匀地) across a face as Westerners do, Easterners 43their attention on the eyes.
“We show that Easterners and Westerners look at different face features to read facial expressions,” Jack said. “Westerners look at the eyes and the mouth in equal measure, whereas Easterners favor the eyes and 44the mouth.”
According to Jack and her colleagues, the discovery shows that human 45of emotion is more complex than previously believed. As a result, facial expressions that had been considered universally recognizable cannot be used to 46convey emotion in a cross-cultural situation.
The researchers studied cultural differences in the 47of facial expressions by recording the eye movements of 13 Western people and 13 East Asian people while they observed pictures of 48faces and put them into categories: happy, sad, surprised, fearful, disgusted, angry, or neutral (中立的). They compared how accurately participants read those facial expressions using their particular eye movement strategies.
It turned out that Easterners focused much greater attention on the eyes and made 49more errors than did Westerners. “The cultural difference in eye movements that they show is probably a reflection of cultural difference in facial expressions,” Jack said. “Our data suggest that whereas Westerners use the whole face to convey emotion, Easterners use the eyes more and mouth less.”
In short, the data show that facial expressions are not universal signals of human emotion. From here on, 50how cultural factors have differed in these basic social skills will help our understanding of human emotion. Otherwise, when it comes to communicating emotions across cultures, Easterners and Westerners will find themselves lost in translation.
