Номер 4, страница 195 - гдз по английскому языку 10 класс учебник Юхнель, Наумова

4. a) Read some of the questions teenagers asked scientists in "I'm a Scientist, Get me out of Here!" Do you think scientists can give the answers to all questions? Can you answer any of them?

1. Do you think that there will be another ice age? 2. Can you make a clone of yourself? 3. Why is it impossible for us to imagine a 4D world? 4. What came first, the chicken or the egg? 5. Do you think we will ever find a way to live forever? 6. Why is ice clear and snow white? 7. Why do you think that humans are the only species on Earth to have advanced in technology? 8. What do you guys actually do? 9. Have you ever invented anything or discovered anything new?

b) Match the answers to the questions above.

A. Is it?! We live in one! Time is the 4th dimension. If you can imagine your house last year, there, you've done it!

B. I think some genius minds have decided the egg must have come first. At some point, some egg-laying creature (that could be a reptile!) created an egg that had a small gene mutation. Chicken appeared through some DNA changes in egg cells. So, the egg came first.

C. There has to be another ice age at some point – the Earth's climate is always changing. I'm not sure when it will be though. Some people are arguing that the next one could start in just a few years.

D. Me personally? No – I don't have the skills. But there are some scientists who claim they can do that. The science and technology are pretty much there to clone humans – the big issues are moral: Is it right to do this? Many people would say that it isn't – partly because there are issues with how healthy clones are, and partly because cloning brings up very important questions of human rights, and what it actually means to be a person.

E. I believe they aren't. Have you seen the Caledonia crows using tools? Various monkeys also use tools for different tasks. I know our technological advancement is much more distinct but other species have advanced too. They haven't advanced further because we've been holding them back. We certainly seem to act like bullies in our dealings with the Natural world.

F. I think that has to do with how closely packed together the water molecules are. In ice, they're tightly together in a crystal-like structure. In snow, there's a lot of little bits of ice just in a kind of pile with lots of air in between; and the air makes it look blue or white.

G. No. Unless you mean by creating digital versions of ourselves that survive after the body has died. We'll probably find a way to live longer, but in the end the laws of physics, chemistry and biology dictate that we can't live for ever.

H. Sleep, party, and have lots of fun... No, sorry – must have been thinking about something else – that doesn't sound like my life at all!

As a professor at a university, I teach people about new technologies and how to use them safely. I write lots of stuff about new technologies – in boring scientific journals and exciting posts on my blog (I'm kidding – they're probably boring as well).

I. I "invented" a device for collecting very small particles out of the air to study them. But it was never made into a commercial instrument. I've also discovered lots of things as a scientist but, to be honest, many of these probably seem quite boring. They're like the bricks that make up a grand building – the bricks are important, but not half so impressive as the overall result of lots of them together. Not that I find my work boring of course!

4. a) Прочитайте некоторые вопросы, которые подростки задали ученым в программе «Я ученый, вытащите меня отсюда!». Как вы думаете, могут ли ученые дать ответы на все вопросы? Можете ли вы ответить на какой-либо из них?

1. Как вы думаете, будет ли еще один ледниковый период? 2. Можете ли вы создать своего клона? 3. Почему мы не можем представить себе четырехмерный мир? 4. Что появилось раньше, курица или яйцо? 5. Как вы думаете, найдем ли мы когда-нибудь способ жить вечно? 6. Почему лед прозрачный, а снег белый? 7. Как вы думаете, почему люди — единственный вид на Земле, достигший технологического прогресса? 8. Чем вы, ребята, на самом деле занимаетесь? 9. Вы когда-нибудь изобретали или открывали что-то новое?

b) Соотнесите ответы с вопросами выше.
