    A very important world problem is the growth of population on the earth. The population of the world today is more than 6,500,000,000. That is a great number and we know it quite well. ①The important thing is not how large the population of the world is now, but is the rate(速度) of the growth. It is about 1.63% every year after the number of dead people has been taken away.

    To give you some ideas of the birth rate, look at the ②second hand of your watch. Every second, four babies are born in the world. Another baby! Another baby! Another baby! Another baby! ③You can not speak quickly enough to keep up with the rate of the growth of the population. It is growing faster and faster. So it goes on, hour after hour. In one day, people have to find food for about 350,000 mouths more.

    This great growth of population will make a big problem by the year 2050 — there will be as many as 7,500,000,000 people on the earth! So this is one of the biggest problems that you are going to meet in your life.

    China and Western countries may have different cultural beliefs about certain animals, but when it comes to pigs, somehow we have the same idea that pigs are ugly and lazy.

    But the truth is that pigs do have some finer qualities. And maybe there's m better time to clear their names than now, with the arrival of the Year of the Pig on Feb 5 this year.

    For starters, science long ago proved that pigs aren't stupid at all. According to a research, "pigs are mentally (精神) and socially like dogs and chimpanzees. They like to play. They can remember things for a long time. And they can tell who treat them welt and who don't.

    There are lovable pig characters in cartoons too. Peppa Pig, a UK animated television series that begin in 2004, has now become one of the most popular cartoons in 180 countries and areas. The four members in the cartoon's pig family teach children from all over the world to get on well with fiends. Their dally stories show that family members are the most valuable persons to cherish (珍惜). And in China, the adventures of McDull, a piglet who works hard towards his dreams even though he keeps failing, have been made into films since 2001. McDull is slow and patient, and not afraid of repeated failures. He has a heart of gold.

    Perhaps these are the qualities of pigs to keep in mind when we celebrate this Chinese New Year—their intelligence (智力), cuteness, patience and innocence.
