题型：单项选择题 阅读表达。阅读下面短文，在表格内的空白处填入合适的答案(每格限填一词)。 We've come a long way from blackboards and chalk. Modern technology (技术) has provided us with lots of ways we can make learning more interesting. Perhaps most importantly of all, it's also more interactive (互动). Some kinds of tools (工具) have been developed. They make the 21st century learning experience much more interactive and interesting. Attracting the attention of students is always difficult, but these tools have made a big difference in how pupils learn. For example, an interactive whiteboard is different from a traditional chalkboard. It allows the teachers to show images and provide sound as well. If you imagine a large computer screen with colorful images and sound added in, you can see why so many pupils are drawn in by what they see and hear in a modern classroom. Various audio (声音的) tools also help to make sure that everyone can hear what the teacher has to say. In the past, if a teacher said something that a child missed, perhaps the child was too timid (胆小的) or nervous to ask them to repeat it. Now they are less likely to miss out simply because they're sitting too far away from the teacher to hear them. The 21st century classroom is able to teach pupils more than one thing. For example, imagine a history lesson is given in a modern classroom. How is it different from a classroom setting in the past? The answer is simple. The students will not only learn about history itself, they will also learn how to use the modern equipment (设备) that helps the teacher get their message across. Modern technology can make teaching and learning easier. Student response (应答) system makes everyone able to express their opinions or answers without having to speak up. Since everyone can do it, the teacher can see who needs more help in other ways. It's clear that this kind of classroom technology is making a great difference in modern classrooms.
