Расшифруйте кросворд . 6 класс​

7.1

В этом задании нужно использовать третью форму глагола (Ved; отмечено жирным) в форме Present Perfect (т.е. по формуле: has/have + Ved) и употребить её так, чтобы логически подытожить данные ранее высказывания (чит. силлогизмы). Как известно, есть правильные и неправильные глаголы — поэтому где-то мы используем т.н. супплетивизм корней, то есть когда корень разнится в зависимости от формы (go - went - gone), или же суффиксацию, т.е. добавляем к основе суффикс -ed (improve - improved - improved). Поэтому выходит так:

Tom is looking for his key. He can't find it. — He has lost his key. (Он потерял ключ.)Margaret can't walk and her leg is in plaster. — She has broken her leg. (Она сломала ногу.)Last week the bus fare was 80 pence. Now it's 90. — The bus fare has gone up. (Плату за проезд на автобусе подняли.)Maria's English wasn't very good. Now it is better. — Her English has improved. (Её английский улучшился.)Dan didn't have a beard before. Now he has a beard. — He has grown a beard. (Он отрастил бороду.)This morning I was expecting a letter. Now I have it. — The letter has arrived. (Письмо пришло.)The temperature was 20 degrees. Now it is only 12. — The temperature has fallen. (Температура упала.)7.3

В этом задании нужно сделать практически то же самое: использовать третью форму глагола в форме Present Perfect, но употребить её не в предложении-следствии, а в ответе. Кроме того, здесь используются краткие формы глаголов, то есть 's и 've (вместо has и have) — разница с полной формой, как известно, в том, что краткая форма — атрибут разговорной речи.

No, thank you. I've just had lunch.I'm afraid, he's gone out.Wait a minute! I've not finished yet.No, I've done it myself / already.Have you found a place to live / anything?I've not decided yet.No, she's come back.

1. Text 5 goes under the title "Phosphorus" and describes this element in the Periodic Table in great details.
2. The author gives many interesting facts concerning the properties and peculiarities of phosphorus and compares it with (w/) nitrogen.
3. Firsly, phosphorus and nitrogen have much in common, but they also differ greatly.
4. While nitrogen is quiete inactive under ordinary conditions, phosphorus reacts rapidly both w/ metals and non-metals.
5. At ordinary temperature, nitrogen is a gas, and phosphorus is a solid.
6. Secondly, phosphorus has the following properties:
- it is almost insoluble in water;
- it dissolves in many solvents.
7. The article goes on that phosphorus exists in several aliotropic forms, only 2 of them are of general interest. One is white phosphorus.
8. The most striking property of white phosphorus is its activity w/ oxygen.
9. It is very combustible, that's why it must be left under water.
10. The author gives some measures of precaution while handling white phosphorus.
11. They are as follows:
- never handle white phosphorus w/ bare hands;
- always remember that it's very poisonous, it may cause chronic poisoning.
12. In the conclusion, it should be mentioned that red phosphorus is a more stable form. It isn't so combustible, but the products formed are the same produced by white phosphorus.
That's about all;-)
