- That’s true, Mary. That’s because my Dad drove me here this morning. Did you see our new French teacher?
- Yes, I did. I met her near the headmaster’s office.
- She looks nice, doesn’t she?
- I think so. Did you learn the lesson?
- No, I didn’t. I had forgotten my workbook at school. I hope she won’t hear the lesson today.
- Let’s hope for the best. In fact the last topic was a bit complicated for me. So I’m not sure I’ve done my homework correct.
- When I have some trouble with my French homework I usually ask my elder brother to help me. He is good at foreign languages.
- You are lucky! By the way, did you study for tomorrow Geometry test?
- Not yet. I’ll start in the evening. How about you? Did you study all the formulas?
- Yes, I did. I have also done dozens of sums. And I have to ask the teacher a few questions before the test. I hope to get a good grade.
- I see. So do I. Are you having lunch in the canteen today?
- No. My Mum gave me a lunch-box for today. Ok, Susan. The bell is ringing. We should have our seats now. The teacher will be here in a minute. Oh, have you got an extra rubber I could borrow? I forgot to bring it today.
- Let me have a look. Yes, I can lend it to you for today. But I need it back. Here it is.
- No problem! Thanks.
Объяснение:
- Привет, Сюзан! Ты пришла сегодня так рано.
- Точно, Мэри. Это потому что мой папа привез меня этим утром. Ты видела нашу новую учительницу французского?
- Да. Я встретила ее у кабинета директора.
- Она выглядит хорошей, правда?
- Думаю, да. Ты выучила урок?
- Нет. Я забыла рабочую тетрадь в школе. Надеюсь, она не будет спрашивать урок сегодня.
- Будем надеяться на лучшее. Вообще, последняя тема была немного сложной для меня. Поэтому я не уверена, что сделала задание правильно.
- Когда у меня возникают трудности с домашней работой по французскому, я обычно старшего брата мне. У него к иностранным языкам.
- Тебе везет! Кстати, ты подготовилась к завтрашней контрольной по геометрии?
- Нет еще. Я начну сегодня вечером. А ты? Ты выучила все формулы?
- Да. И еще решила десятки примеров. И мне нужно задать учителю несколько вопросов перед контрольной. Я надеюсь получить хорошую оценку.
- Понятно. Я тоже. Ты сегодня обедаешь в столовой?
- Нет. Мама дала мне ланч-бокс сегодня. ОК, Сюзан. Звонит звонок. Нам нужно сесть на свои места. Учитель будет здесь через минуту. О, у тебя есть запасной ластик, чтобы одолжить мне? Я забыла сегодня принести свой.
- Дай посмотрю. Да, могу дать тебе на сегодня. Но он нужен мне обратно. Вот, возьми.
If you have even been inside the cockpit of a plane, you will have noticed the large number of instruments on the walls and ceiling around the pilot’s seat. Many of these buttons, dials and screens are used in navigation. Unlike car drivers, pilots do not have the luxury of signs and arrows telling them where to go. Instead, they rely on sophisticated GPS systems. So how were pilots able to find their way in the days before radio and satellite communication?
In the USA, the problem of navigation first arose when the airmail postal service was introduced in 1911. In the beginning, huge bonfires were lit to show pilots where to land in the dark. Later, a more practical solution was found: the construction of giant concrete arrows on the ground. The arrows were 21 m long and painted bright yellow. To enable pilots to see them at night, a steel tower with lights was built in the middle. The top light turned around to attract the pilot’s attention, and two others lit up the arrow and flashed a code to identify its location.
The first of these arrows was laid in 1924, and by 1929, there were around 1,500 of them. They formed an illuminated path for airmail pilots stretching from New York to San Francisco. The arrows were spaced about 16 km apart and were an important part of the Transcontinental Airway System. But by the 1940s, new navigation techniques were being discovered and soon, the arrows and their towers were no longer needed. They were gradually abandoned and some of them were removed completely.
However, not all of the arrows have disappeared. In the state of Montana, they are still used for guiding pilots through the mountains. Some are still visible in the empty areas of other states such as Utah, Wyoming and Indiana. Yet either because of their size or due to their bad condition, the arrows are not easy to find. In many cases, if you want to see one, it is a question of knowing where to look.
Which is where retired couple Brian and Charlotte Smith can help. The two are devoted fans of the arrows and spend much of their time hunting them down. So far, they have located more than a hundred of them. Once they find an arrow, they map its location, photograph it and upload the details onto their website. Their aim is to preserve the memory of these historical structures and prevent them from being lost forever.
