Вопрос по английскому языку:

Anthony and Beth are discussing a magazine article about new technologies. Complete their conversation by choosing the correct verb forms from the drop-down menus (a–l). Then decide what type of new technology they are discussing in each part of the conversation (1–4). Again, choose from the drop-down menu.

(1) ___________________

Anthony: Have you seen this article in the New Scientist? It’s all about new technologies. It’s fascinating.

Beth: Go on, then. How (are our lives going to change/will our lives be changing)?

Anthony: It’s predicting that pretty soon scientists (are going/will) to be able to make devices like computers and robots using single cells and atoms.

Beth: Wow. To do what?

Anthony: Well, they’re talking about being able to treat diseases at a cellular level by injecting one of these miniature robots, or using the technology to make new, more flexible materials from carbon atoms.

Beth: What (will they think of/will they be thinking of) next?

(2) ___________________

Anthony: Well, it’s funny you should ask. The article goes on to talk about things like robotics and androids.

Beth: Androids?

Anthony: Yeah. It says that by 2050, scientists (will build/will have built) androids that look like humans and have the capacity to interact like humans.

Beth: I don’t think I like that idea. I think it (‘ll be/’ll have been) more trouble than it’s worth. Imagine everything that could go wrong!

(3) ___________________

Anthony: OK, I think you (‘ll like/’ll be liking) this next one more. How about having a computer that controlled all of the appliances and electronic equipment in our house? It would save money because the house would know when you weren’t home, and it’d make sure everything was turned off.

Beth: It (‘ll probably be/’ll probably have been) expensive, though, I imagine.

Anthony: Who knows how much things (will cost/will be costing) in future! Perhaps (we’ll all have lived/we’ll all be living) on the Moon by then!

(4) ___________________

Beth: What does that last bit of the article say? The bit with the photo of that small microchip?

Anthony: Hang on a minute, I (‘m going to/’ll) look. Umm ... it’s talking about a type of technology that uses radio waves and these things called ‘tags’ to identify people.

Beth: People? So they could embed one of these tags in me?

Anthony: Well, in theory, yes. But they’re mainly used on animals – so you can track your pet if they vanish – and on products in shops – so that they can stop people stealing.

Beth: Mmm. It still sounds suspicious to me.

Anthony: Well, it does say here that some organizations are worried about privacy issues.

Beth: I do worry that in the future, governments and big corporations (will be using/will have used) all of these new types of technology to keep us under control.

Anthony: You worry too much. Here, you finish the article. I (‘ll make/’ll be making) us a nice cup of tea.
