A、They may be addicted in surfing online. B、Their study may be influenced. C、They might lose their literacy and they cannot writ

M:Speaking of the subject of today, (12)what changes have you seen happening in digital learning in China?
W:I think there are some very good experimental projects, for example, I mentioned that Pro. He from BNU—Beijing Normal University. They are doing some very interesting experimental projects in some schools. (13)I think, there’ re about 50 schools where they have a lot of computers and they are really letting the students spend a lot of time with their computers. So I was impressed with that. I didn’t expect to see such…
M:Dramatic changes?
W:They’re relatively large-scaled, 50 schools, although it is not 50,000 schools. It is not just one classroom. That’s study. It is quite a substantial size. That is just one example. My impression is that they are all quite a few people doing very interesting research projects, in order to do with digital education.
M:Are you encouraging students to spend more time online by using computers, I mean, surfing?
W:They don’t need to be encouraged. They’re all doing that.
M:Yeah,they are doing that on their own, but the problem is that some of parents have the concern. (14)If children spend much more time surfing online, they might lose their literacy and they cannot write. That might be the problem.
W:Well, first of all, that is not necessarily true. You can’t generalize. It is true that you could waste your time surfing, but you could also do serious work surfing. So it depends on what they are doing.
M:And the age of the students?
W:I don’t think it depends on the ages. Like the experiment I mentioned that Pro. He is doing that these are first and second grade students. They are just learning to write. (15)Why are they learning to write? Because they find interesting things to read on net. By surfing, of course they learn to read and as they learn to read, they also learn to write. That’s an example. Surfing helps them improve writing. They write better, they learn more than the other students. It’s true that you can see the opposite also.
