阅读下面短文，根据短文内容完成句子。
There are many inventions that have caused great changes in the world. Here is a short introduction of the maglev train (磁悬浮). The history of the maglev train started in the beginning of the 1900s. The American Robert Goddard and the French Emile Bachelet came up with the idea of frictionless (无摩擦的) trains. But scientist didn’t succeed in making it at that time.
About 60 years later, the Japanese started their research on maglev transportation. After many years of experiments, the Japanese began to build their first test line. 7 km in 1975, and finished it in 1977. Many test runs started in July, 1977 with a speed of 517 km/h. In 1990, Japan built the Yamanashi Maglev test line. This test line was 42.8 km long and the first running test was held in 1997.
The Germans also started research on the maglev train in the early 1970s. It took them ten years to make the first track(ti)model. In 1993, the longest nonstop test running was 1,674 km. That same year the speed reached 450km/h.
China finished a 30-km-long maglev train line in Shanghai in 2003. This is the first commercial (商业的) maglev train line in the world. Although this project cost over 1 billion dollars, we should feel proud of it.

3.The Germans spent ________ in making the first track model.

One morning, Wu Li discovered that her classroom had changed. She found that the desks were no longer in rows(排), but pushed together to make eight bigger desks. She was too excited about it for the first two days and she couldn’t listen to the teachers carefully. But soon she and her classmates got used to this new classroom arrangement (安排). “Now our class is quieter,” said Wu. “What’s more, we can come up with our own ideas and learn more through discussion. It’s a better way to study.”
Li Yu liked it, too. He said, “Group members first discuss, and then show ourselves in front of the whole class. It makes us believe in ourselves.” It was part of a reform (改革) at Li’s school—Baita Secondary School. The school made this reform because they wanted to provide students with easier ways to study and more chances to discuss. “Our school hopes it can improve students’ abilities (能力) to study by themselves and work in groups,” said Zhang Yong, the principal of the school.
However, the reform has demanded (要求) more from teachers. Now they have only about 15 minutes to give the lesson which should be taught in 45 minutes before. It is difficult to teach in such a short time. The teachers have to find better ways to teach more effectively.
“The reform demands more, but I’m sure it is helpful,” added Mr Zhang.
1.After the new classroom arrangement it was easier for Wu Li and her classmates to ______ in class.
A. discuss with each other B. sit in the classroom
C. push desks together D. teach a lesson
2.The school made the reform to provide students with _______ to study.
A. noisier classes B. easier ways C. more seats D. fewer chances
