Types of quetions

Tell me about the different types of public transport in your city.

Begin with an opening phrase：

Well actually...
Of course, you know...
Sure, obviously...
Of course, it goes without saying...
OK, certainly...

Then use one of the following:
...there's quite a mixed variety of...
...there's quite a wide range of...
...there's a fairly broad range of...
...there's quite an extensive diversity of...
...there's quite a diverse mixture of...

the opening line might be:
Of course, it goes without saying that there's quite a mixed variety of public transport in my city.

use the following structure to introduce the first type:
But I guess the most+adj....would probably be...
However, I suppose the most+adj. ...could possibly be...
Though I think the most+adj.... would potentially be...
Yet I imagine the most+adj...may well be...
Still, I suspect that the most+adj....could perhaps be...

adj. common普通的 commonplace平凡的 influential有影响力的  popular流行的 frequent频繁的 prevalent流行的
fashionable赶潮流的 trendy时髦的 notorious声名狼藉的 famous出名的 well-known知名的
crucial至关重要的  widely-used普遍使用的 widely-known有名的 prominet显著的
important重要的  significant意义重大的 widespread普遍的 standard标准的 conventional传统的 celebrated著名的 hip新潮的 with-it时新的 commonly-used 常用的 usual平常的 customary习惯的
commonly-known众所周知的

 renowned有名的

the first sentence could be:
Of course, it goes without saying that there's quite a mixed variety of public transport in my city. Though I think the most commonly-used would potentially be buses.

Use a phrase to add a detail:
The thing with bused is that...
I assume buses are so+adj. because...
The point I want to add about bused is that..
And what you have to realize with buses is that...
And the explanation for this could be that...
And the basis of this is that...

the first part of the answer could be:
Of course, it goes without saying that there's quite a mixed variety of public transport in my city. Though I think the most commonly-used would potentially be buses. And the explanation for this could be that they are so cheap and reliable. In fact the average bus fare in my city is about one yuan for a single journey.

Use a linking phrase to introduce a second type.
Besides(buses),...
As well as(buses),...
In addition to(buses),...
Another kind of (public transport)would be...
Another form of (public transport)worth mentioning could be...
A second variety of (public transport)would be something like...
A subsequent category would be something like...

next part of the answer might be:
As well as buses, a second variety of public transport would be something like taxis.

Add a linking phrase to develop the second type:
And the main characteristic of (taxis)is that...
And the unique aspect of (taxis)is that...
And one exceptional aspect with(taxis)is that...

add the detail with a linking word to form a complex sentence:
As well as buses, a second variety of public transport would be something like taxis. And one exceptional aspect with taxis is that they are certainly the quickest way to get around town. So if you're in a hurry then taxis are the best bet(=the best choice).

add a vague end line:
And of course there's the usual things like...
And obviously you can also find things like...
Likewise, as might be expected, there are things like...
And naturally, there are things like...

the final sentence might be:
Likewise, as might be expected, there's things like ferries, motorcycle taxis and trains, although these are not as widely-used as the first two that I mentioned.

the finished structure might look something like:
Of course, it goes without saying there's quite an extensive diversity of...(topic)Still, I suspect that the most+adj.could perhaps be...(type1)And what you have to realize with...(type1)is that ...In fact/so/but/because...(detail1)
Another form of ...(topic)worth mentioning could be...(type2)And the main characteristic of ...(type2)is that...(detail)(+linking word/complex structure)
And naturally, there's things like...(2 or 3 other types)
