阅读理解。 A teacher from America visited a school in China. In one class, she watched sixty children learn to draw a cat. The teacher drew a big circle on the blackboard, and sixty children copied it on their paper. The teacher drew a small one on the top of the big one and then put two small triangles (三角形) on the top of it. The children drew in the same way. The lesson went on until there were sixty-one cats in the classroom. Each student's cat look exactly the same as that on the blackboard. The visiting teacher watched the lesson and was surprised because the teaching methods were different from those in her country. A children's art lesson in her country produced a lot of pictures, and each one is quite different from the others. Why? What makes this difference in educational methods? In a classroom in any country, a teacher teaches more than art or history or language. In a country such as the United Sates or Canada, students are asked to work and find answers by themselves. The students are helped to learn to have their own ideas. In countries such as China and Japan, students often work together and help each other in the classroom, but the teachers teach, and the students listen. The students are asked to memorize a lot. They have to learn the same textbook, do the same homework and give the same answers. 1. Which of the following looks like the cat on the blackboard? A           B             C          D 2. The students in _______ are helped to find answers by themselves. A. Japan B. China C. Australia D. America 3. The word 'memorize' means _______ in the passage. A. remember B. forget C. give D. lose 4. Which of the following is true? A. There are sixty-one students in the class. B. All the students in the class are good at drawing cats. C. The visitor was surprised at the art lesson. D. In the United Sates, the students learn the same textbook, do the same homework. 5. The writer of the passage thinks that the students should _______.
