Q: Article: Labor force is defined as being the total number of people who are available to work and earn income. This definition includes everyone who is employed or seeking paid employment, so it includes employers and the self-employed. Labor is one of the country's resources which can be combined with other resources to produce the goods and services wanted by the community. Although the size of the workforce depends a great deal on the size of the total population, there are several other influences which also affect it. The age distribution of the total population has a very marked effect on the available workforce. If the population has a high proportion of very young people or of those too old to work, then the available workforce would be lower than if there were a balanced spread age distribution. If the population naturally grows rapidly, the number of births greatly exceeds the number of deaths then as a total population increases proportion of the workforce declines. Sometimes a population is described as aging which means that the birth rate is either falling or growing very slowly, and as people retire from the workforce there are insufficient numbers of young people entering it to replace those who are leaving it. In that situation the population is top-heavy with older people. So the percentage of the population in the workforce declines when there is either a rapid increase in births or a falling birth rate. The age distribution of the population has several important effects on the economy. If the population is aging and there is an increase in the number of people retiring without a corresponding increase in the number entering the workforce, this raises the problem of the ability of the economy to provide a reasonable level of social services to the retired group. If the aged are to be cared for in special homes, finance must be available for that purpose. If the size of the workforce is small to the total population, then the government tax revenue is ly low and either the government has less money available to it or workforce members have to be taxed more heavily.

Q: Article: The world has a fast growing population and people need more land for houses, factories, highways, and so on. The farmland is decreasing with each passing day. How to meet the need of feeding the growing population? One way is to introduce some high-output gene into a crop to enable it to produce more. Biologists over the years have discovered genes which can raise output of the crops, resist pests, improve taste, etc. However, in many western countries there is widespread concern over the safety of"Genetically Modified"(GM) foods, because they think there may be serious problems of environment, health, safety, morality and so on. As a scientist I must admit GM foods involve great risks to humans. In fact in Europe they're called "Frankenstein foods" by many. Frankenstein is a character in a novel. He was a very clever scientist. He created a monster , which eventually killed him. Soybeans can be made into many foods. However, it's hard to _ . Therefore, it's very important we have to make sure the soybean, if genetically modified, is free from any poisonous matter harmful to human beings. For this we need very good testing. We do have some testing on some animals, but no completely satisfactory testing has ever been made so far. They're entirely new, and their problems are entirely unknown. It takes time to develop persuasive tests to know whether they're harmful to us or not. We may not be able to tell what may happen if we take GM foods. Some of them may be resistant to antibiotics . Then many of the medicines we have today will have no effect on people eating GM foods. A more likely case is the GM foods may contain genes some people are allergic to. GM products have already come into our lives but most people even know nothing about it. At least we have to be clear about what we are eating. The China Consumers Association is calling for labeling on GM foods so that consumers will know before they buy them.
Answer: feed the fast growing population

A: The chief purpose of developing GM foods is to _ .

Q: Article: Earlier this year,my oldest daughter got braces on her teeth,and let's just say she did not go quietly into that dentist's chair.Fear and hate pretty much describe the days leading up to her first appointment. So when she finally walked out with shiny teeth,a sore mouth and a broken spirit,I told her I was proud of her and took her to Ben &Jerry's for an ice cream reward.Two weeks later,we returned to the scene of the crime.The dentist spent about 45 seconds checking her teeth before sending her on her merry way.Before I could start the car, she was placing her ice cream order.She was shocked when I told her that she wasn't going to get a reward every time we get her teeth checked. Clearly,she's not alone.According to some parenting experts,kids are easily addicted to a benefit--producing system of parental rewards and bribes--it's not all ice creams,candies and cool toys.Some parents are offering their children prizes to just let them sit down and behave in a restaurant--or sleep in their own beds--or score a goal in the next soccer game. While the experts agree that occasional awards are okay, the danger lies in the system's overuse.Kids quickly gain a sense of entitlement ,where they come to expect a big reward for every good thing that they do,no matter how small.To keep things in check,experts say parents should reduce the number of rewards they offer,make sure rewards match the behavior and explain the real benefits of behaving for the sake of behaving. Have you used bribery or a reward system with your kids? Was it successful? Do your kids expect more because of that system?
