Read the following article and select the best answer. Article: Recently,scientists attending a meeting in Chicago presented new studies showing how food and its production affect global warming.They offered some suggestions for how to eat in a more environmentally friendly way. For many years,scientists have warned us that our planet is getting warmer.If current trends continue,animals may start to die off and life could get very difficult for everyone.The temperature is rising because humans have been releasing massive amounts of greenhouse gases into the atmosphere,which surround the planet and keep heat from escaping.One of these gases is carbon dioxide. Most carbon dioxide we produce comes from the process of making and eating food,the scientists reported in Chicago.The production of meat contributes to a lot of carbon dioxide.And much of meat's contribution comes from beef,which is responsible for releasing even more greenhouse gases into the atmosphere. The process of making a hamburger,for example,requires a lot of energy.A cow has to be fed and raised,and cow's wastes are a major source of greenhouse gases.After the cow is killed,the meat has to be processed and shipped to a consumer,which takes fuel.And most of the cow won't even be used for meat people eat. By the time a hamburger finally lands on a dinner plate,it has taken a heavy toll on the environment.It is believed that the process of making a halfpound allbeef burger adds about 19 times the weight of hamburgers in carbon dioxide. The message is clear:We can greatly reduce the production of greenhouse gases by eating less beef.Other kinds of meat like pork and chicken do less harm to the environment--at least in terms of the amount of greenhouse gases released.Nathan Pelletier,a scientist at Dalhousie University in Canada,reported that if everyone in industrial countries ate chicken instead of beef,we would cut the Earth's greenhouse gases by more than half. All kinds of meat,the scientists reported,are harder on the planet than vegetables.To grow and eat a pound of potatoes,for example,sends less than... Question: What is likely to happen if the climate is getting warmer according to the passage? - Sea level will continue to rise sharply. - Human beings won't have enough food. - It would be very hard for man to survive. - All the animals and plants will disappear.
It would be very hard for man to survive.

Q: Read the following article and select the best answer. Article: Is early childhood education really necessary? Early childhood education primarily focuses on learning through playing to develop the child's physical, sensory, communicational and social development.Early childhood education has become a concern of the government, who pushes poor children to be formally trained before they are old enough for Kindergarten. There are good reasons for the government to push early childhood education.Studies have shown that orphaned children who did not receive good care and education become developmentally delayed causing failure in school, and even in life.Further studies show that poor children who take part in Head Start programs are more prepared for school, less likely to end up in Special Education classes, and are less likely to receive public help or go to jail. There are also negative parts to putting a child in formal education programs too early.Time Magazine online explains that "the younger the child the less his chances of catching up with first-grade work." I have personally witnessed many children of my generation who went to Head Start programs become frustrated and bored with school before they finished high school.Yet parents have been sure that the earlier the child starts school, the better off he or she is, so they push to start children earlier. Actually while early formal education of poor children does show great gains in the early elementary years, studies also show that this head start is really a "false start", as the gains are lost in middle and high school years.It seems that environment is a bigger factor on life's success than early education.Head Start programs have not achieved its original goal in closing the achievement gap in poor and middle school children.Perhaps it is time to find other ways to close that gap. Question: The purpose of the government valuing the early childhood education is _ . - to develop the children's communication - to give orphaned children good care and education - to get the children prepared for the kindergarten - to train the children formally and regularly
A: to get the children prepared for the kindergarten

Buses, cars and taxis were not able to run and were standing by the side of the road. People were trying to find their way about on foot but were losing their way in the fog. Mr. Smith had a very important meeting at the House of Commons and had to get there but no one could take him. He tried to walk there but found he was quite lost. Suddenly he bumped into a stranger. The stranger asked if he could help him. Mr. Smith said he wanted to get to the Houses of Parliament. The stranger told him he would take him there. Mr. Smith thanked him and they started to walk there. The fog was getting thicker every minute but the stranger had no difficulty in finding the way. He went along one street, turned down another, crossed a square and at last after about half an hour's walk they arrived at the Houses of Parliament. Mr. Smith couldn't understand how the stranger found his way. "It is wonderful," he said. "How do you find the way in the fog?" "It is no trouble at all to me," said the stranger, "I am blind."
