(I=Interviewer L=Li Xing)
I: Welcome to Teen Tech Talk. Nowadays, we use many
software applications on our mobile devices. We call
them apps for short. Today, my guest is Li Xing, an
app developer from New-tech Company. Hi, Li Xing!
L: Hello! Thanks for having me.
I: So, in your opinion, why are apps so popular
L: Well, apps are very useful. They help us find
popular restaurants, call for taxis, find directions to
different places, and so on.
I: Indeed. They make our life much easier, don't they
As many of our listeners are students, could you tell
us something about educational apps
L: Sure. Educational apps are becoming increasingly
powerful. For example, some apps allow students to
choose their online teachers and subjects according to
their personal interests and needs. They also ensure
that students can all enjoy the same learning materials,
even when they're not sitting in the same classroom
together!
I: Sounds fantastic! But developing an app must be
difficult, right
L: Well, yes. The most difficult thing is finding out what
people need and solving real-world problems.
I: Solving real-world problems, that does sound
challenging. What apps are you working on right now
L: We're working on using the latest technologies in our
apps, like VR, AR and MR.
I: How exciting! Let's continue this discussion after the
break…
