основная идея текста. Переведите абзац на русский язык.
Часть II.
Задание 1. Прочитайте текст В и ответьте на вопрос: What kind
of sugars do you think is responsible for more sweet taste?
Text B. Carbohydrates.
1. Among the common carbohydrates are sugar and starch. These
are composed of the chemical elements: carbon, hydrogen, and
oxygen.
2. Sugar is a broad term applied to a large number of carbohydrates
that have a more or less sweet taste. To most people sugar means
cane or beet sugar. These two sugar crops serve as the sources of
commercial sucrose. However, there exist different kinds of
sugars such as fructose, lactose, and maltose found rather
widely distributed in foods.
3. In natural food substances fructose is likely to be associated with
glucose. Glucose and fructose are simple sugars found in many
fruit and honey. Sucrose, the most widely used sugar, is
composed of a molecule of glucose and one of fructose in
chemical combination.
4. Starch is widely used both as a foodstuff and as a raw material
for different industries. Starch is formed in all green plants.
Commercially starch is extracted from maize, wheat, rice,
barley, rye, oats, buckwheat. Potatoes are also used for the starch
production.
5. Carbohydrates are classified as mono-saccharides, disaccharides,
trisaccharides and polysaccharides. Glucose or dextrose is a
monosaccharide. Common sugar or sucrose is a disaccharide.
Starch is a polysaccharide.
Задание 2. Прочитайте текст еще раз и запишите в тетрадь №
абзаца, в котором говорится а) о различных видах сахаров; б) о
продуктах, содержащих фруктозу и глюкозу; в) о продуктах,
содержащих крахмал; г) о классификации углеводов.
Задание 3. Укажите № предложений (утверждений), которые
соответствуют содержанию текста:
1. Sucrose is available in large quantities from the sugar cane and
the sugar beet.
2. Lactose, a sugar found only in milk, is obtained as a by-product
in the manufacture of certain milk.
3. Starch is a carbohydrate more complex in nature than any of the
sugars.
4. All the sugars are responsible for a sweet taste.
5. The commonest examples of carbohydrates are the various
sugars and starch.
6. Sugars and starches are digested rather quickly and supply
energy for the body.
7. Carbohydrates consist of carbon, hydrogen and oxygen.
