2. Что измеряют врачи? продавцы? портные? спортивные судьи? Какими измерительными приборами они при этом пользуются?
Решение. №2 (с. 220)
Врачи измеряют множество показателей здоровья пациента. К основным относятся: температура тела, артериальное давление, масса тела, рост, частота сердечных сокращений (пульс). Для этого они пользуются специальными медицинскими приборами: термометром (градусником), тонометром, медицинскими весами, ростомером, секундомером или пульсоксиметром.
Ответ: Врачи измеряют температуру (термометром), давление (тонометром), массу (весами), рост (ростомером), пульс (секундомером).
Продавцы измеряют характеристики товаров для определения их стоимости. Чаще всего они измеряют массу (например, фруктов, круп, конфет), длину (ткани, кабеля, лент) и объем (жидкостей). Для этого они используют весы, метр или рулетку, а также мерные емкости (например, мерные стаканы).
Ответ: Продавцы измеряют массу (весами), длину (метром, рулеткой) и объем (мерными емкостями).
Портные производят измерения для создания одежды по индивидуальным параметрам. Они измеряют размеры тела клиента (обхват груди, талии, бедер, длину рук и ног) и отмеряют необходимое количество ткани. Их главные измерительные инструменты — это сантиметровая лента и линейка.
Ответ: Портные измеряют размеры тела человека и отрезки ткани с помощью сантиметровой ленты и линейки.
Спортивные судьи фиксируют результаты соревнований, которые часто выражаются в физических величинах. В зависимости от вида спорта они измеряют время (в беге, плавании), расстояние или длину (в прыжках, метании копья или диска), высоту (в прыжках в высоту или с шестом). Для этого они применяют секундомеры, измерительные рулетки, лазерные дальномеры и специальные измерительные планки.
Ответ: Спортивные судьи измеряют время (секундомером), расстояние (рулеткой, дальномером) и высоту (измерительной планкой).
