Hi,

Students should be encouraged to use __the___ Internet as ___a__ resource.

Why "the" Internet ? not just "Internet"? Just because there is only one internet in the world, so we use "the" ? Originally, there were various networks, so we would make a specific reference to 'the inter network'. Now, everybody knows about 'the Internet', but we just keep the habit of taking about it that way.

I ate the sandwich while I was waiting for a 20:08 train.

Why "the sandwich", not "a sandwich" ? It's not a speacial sandwich, it's just a regular sandwich, Right? Say 'the sandwich' if you are talking about a specific sandwich that you already mentioned. If it's the first time you mention it, say 'a sandwich'. In your example here, it sounds like it should be 'a sandwich'.
And I don't why it uses " a " for "20:08 train", it's not any train, it's the train which arrived at 20:08, so I thought it should use " the" .... Please help me to understand this concept. Yes, say 'the' is there is only one '20.08 train'.

In many places in China, the_ bicycle is still _a popular means of transportation. <-- Can someone tell me why? I usually use "the" in front of an adjective, please help me to clarify this. 'The bicycle' is used here as a way of referring to bicycles in general. When we speak this way, with one single thing representing all such things, we say 'the'.

Q 4. Have you read book called Waiting for Anya? <--- Is this right? I think it needs "a" in front of "book" . Am I wrong? No, you're right. You need 'a'.
