1 How have TV programs changed in China?
Thinking about it, I would say that they've changed quite a lot. And to begin with, I guess one of the biggest changes would be that in the past, there used to be only a limited variety of programs, whereas nowadays, there is a much wider range of things on TV, such as talent and dating shows. Another thing is that TV programs nowadays are all in color, whereas in the past they used to all be in balck and white. So yeah I guess these would be the main changes.
这里的逻辑说了两个变化，个变化是节目的种类，第二个是节目彩色与否。并且都是过去和现在分别都得提到。

2 How has the relationship between neighbours changed between now and the past?
I'd say it's changed a lot, and probably the main change has been that nowadays, people don't really see their neighbours all that often, whereas in the past, they used to do quite a lot of things together. For example, people would often have their neighbours over for lunch or dinner, which doesn't happen that much any more.

短语：
have sb. over for lunch or dinner 邀请某人过来吃饭

3 Have cities changed much in your country in the past few decades?
Yeah, I'd say they definitely have, because firstly, they've become a lot more built-up, and so there are considerably more high-rise buildings than there used to be. And as well as this, another big change would be the traffic, which has got quite a lot worse in most cities, simply because there are far more cars on the road than there used to be. 

短语：
built-up adj. 建筑物密集的
considerably  adv. 相当地，非常地

4 Is it easier or more difficult to get a job today than in the past?
Well, I would say it's definitely more difficult to get a job nowadays than it was in the past, and one of the reasons for saying this is that in the past, there was generally less competition for jobs, because not that many people went to university, whereas nowadays, there are millions of graduates looking around for jobs, which has made it extremely difficult finding a decent, high-paid job, unless of course you have good personal connections! And as well as this, another point I should mention is that 20 or 30 years ago, people were actually assigned jobs after completing university, so getting a job was  pretty much guaranteed, whereas nowadays this is not the case at all.

decent =good
high-paid job 高薪工作

5 Is the material that furniture is made from today different to the material that was used in the past?
Yeah, I would say it is, because in the past, furniture mostly used to be made of wood, whereas nowadays, there's a huge variety of different materials that are used for making furniture, of which a few that come to mind are plastic, leather and suede. And I think this reflects the fact that people's tastes are diversifying as their standard of living improves.
