  It isn't strictly true that one half of the world is rich and the other half is poor. It is one-third that is very rich and two-thirds that are very poor.

  People in the rich countries don't understand the great difference between them and those in the poorer countries. A very simple example is that a dog or a cat in north America eats better than a child in the poorer countries. A fisherman in South America may be catching fish which is processed into pet food, and his own children are not getting enough to eat for their bodies to grow properly.

  Although a lot of the world's natural resources like oil come from these poorer countries, people in the richer countries are using about sixty times as much of these resources as people in Asia or Africa. And it's the richer countries that decide what kind of prices they are ready to pay for these resources. And the prices the richer countries get for their own exports, however, are always rising. So they are getting richer and richer and the poorer countries are getting poorer.

How do you get on with your teachers? Every day, we spend hours with our teachers at school. We 41  them, and they teach us to be good people. The relationship between students and teachers is very important.

   Teachers care about our studies and lives, and it seems they know everything about the subjects they teach. They also have the right (权利) to decide  42  should be the class leaders or represent the class to take part in the activities.

   So, many students want to be the teacher' s pet. We 43 teachers great respect. In class, we obey the rules and keep  44  if the teacher doesn' t ask us to speak. We  45  have opinions different from our teachers'. When they make a mistake, we are afraid to point it out. Some of us don ' t want to contact teachers after class because we don' t want to bother (打扰) them.

   At American 46. , the situation is a little different. Teachers and students are more like friends.  47  a teacher by his or her name is common. In class, students express their opinions  48 and challenge (挑战) teachers when they don' t agree. If it lures out that a teacher made a mistake, the teacher will say " 49 " in front of the whole class. Students and teachers also

communicate through e-mail, Facebook or Twitter after class. They chat 50  studies and life experiences.

   Teachers are like our parents and our friends. So we should respect our teachers.
