One factor that can influence consumers is their mood(情绪) state. Mood may be described 1 a temporary and mild positive or negative feeling that is generalized and not tied to any particular circumstance. Moods should be 2 from feelings which are usually much more stronger 3 to specific circumstances, and often conscious. In one sense, the effect of a consumer’s mood can be thought of in 4 the same way as our reactions to the 5 of our friends — when our friends are happy and “up”, that tends to influence us positively, but when they are “down”, that can have a negative impact on us. 6, consumers operating under a given mood state tend to react to stimuli(刺激因素) in a direction consistent with that mood state. Thus, for example, we should expect to see consumers in a positive mood state evaluate products in more of a 7 manner than they would when not in such a state. Moreover, mood states appear able to enhance(增强) a consumer’s memory.
Moods appear to be readily influenced by marketing 8. For example, the rhythm(节奏), pitch, and volume of music has been shown to influence behavior such as 9 of time spent in supermarkets or intention to purchase products. In addition, advertising can influence consumer’s moods which, in 10, are more likely to influence consumers’ reactions to products.

An important factor that plays a part in susceptibility （易受影响） to colds is age．A study done by the University of Michigan School of Public Health indicated the fact that seems to hold true for the general population．Babies are the group suffering most from colds, averaging more than six colds in their first years．Boys have more colds than girls up to age three．After the age of three, girls are more susceptible than boys, and teenage girls average three colds a year to boy's two．

The general frequency of colds continues to decline into adults．Elderly people who are in good health have as few as one or two colds annually．One exception is found among people in their twenties, especially women, who show a rise in cold infections（感染）, because people to this age group are most likely to have young children．Adults who delay having children until their thirties and forties experience the same sudden increase in cold infections．

The study also found that economics （经济状况） plays an important role．As income increases, the frequency at which colds are reported in the family decreases．Families with the lowest income suffer about a third more colds than families at the upper end．Lower income generally forces people to live in closer quarters than those typically occupied by wealthier people, and crowding increases the opportunities for the cold virus to travel from person to person．Low income may also influence diet．The degree to which poor nutrition affects susceptibility to colds is not yet clearly proved, but an inadequate diet is suspected of lowering resistance generally．

1．What factors cause people to catch colds easily?

       A．Age and pregnancy．

B．Health and pregnancy．

2．Why does the lowest income lead to the rapid spread of colds?

       B．Because balanced diet has definitely affected poor people．

       C．Because people with the lowest income have limited living space．

Eating too much fatty food, exercising too little and smoking can raise your future risk of heart disease. But there is another factor that can cause your heart problems more immediately: the air you breathe.
Previous studies have linked high exposure (暴露）to environmental pollution to an increased risk of heart problem, but two analyses now show that poor air quality can lead to heart attack or stroke (中风）within as little as a few hours after exposure. In one review of the research, scientists found that people exposed to high levels of pollutants (污染物）were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA) considers to be of “moderate” (良好）quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure.
The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.

Eating too much fatty food, exercising too little and smoking can raise your future risk of heart disease. But there is another factor that can cause your heart problems more immediately: the air you breathe.

Previous studies have linked high exposure (暴露）to environmental pollution to an increased risk of heart problem, but two analyses now show that poor air quality can lead to heart attack or stroke (中风）within as little as a few hours after exposure. In one review of the research, scientists found that people exposed to high levels of pollutants (污染物）were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA) considers to be of “moderate” (良好）quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure.

The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.

Eating too much fatty food, exercising too little and smoking can raise your future risk of heart disease. But there is another factor that can cause your heart problems more immediately: the air you breathe.

Previous studies have linked high exposure (暴露）to environmental pollution to an increased risk of heart problem, but two analyses now show that poor air quality can lead to heart attack or stroke (中风）within as little as a few hours after exposure. In one review of the research, scientists found that people exposed to high levels of pollutants (污染物）were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA) considers to be of “moderate” (良好）quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure.

The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.
