【填空题】再听录音或仔细阅读文本，并完成测验。 Programming Languages Student: Professor Martin, I just finished my Java assignment, but I still have some questions. Instructor: Sure, Andrew. Student: I’m having a hard time keeping all the languages straight. There are so many. Instructor: There are quite a few. Which ones are you having trouble with？ Student: All of them. I think it’s confusing to have all these （1）. Instructor: I see where you’re coming from. It’s a lot to learn. Student: But why are there so many different languages？ Instructor: The first reason is that it makes developing （2） easier. Student: How is that？ Instructor: The computer only understands commands in （3） language, or （4） digits. It would take programmers a long time to write programs in binary format. Student: I see. Instructor: Instead, programmers use human readable （5） languages, like Java. That allows us to write programs faster than ever before. Student: I understand that. But why are there so many human-readable programming languages？ Instructor: Some human-readable programming languages are more appropriate for certain kinds of software. Does that answer your question？ Student: Yes. I guess that makes sense. Thanks.
