Exports are either raw materials or manufactured goods. Raw materials are products of the land, such as cotton, timber or rubber. Some raw materials, such as iron ore, come from mines. These raw materials are often exported by the countries that produce them to other countries where they are made into manufactured goods. Some countries produce food for export, for example, meat, sugar, or cereals such as wheat and maize. These countries are agricultural countries. An agricultural country needs fertile land and a good climate. A cold, dry climate is not suitable for agriculture. A country which produces manufactured goods is known as an industrialized country. An industrialized country cannot always produce enough food for its own needs. In this case, it does not export foodstuffs. Instead it has to import them. It relies on exports of manufactured products and pays for imports with the money it earns from the exported goods. From the first sentence of the passage we can know that there are()kinds of exports.

Practice 2 ● Look at the graphs below. They show the imports and exports of eight different countries(A-H).
● Which graph does each sentence (11-15) describe?
● For each sentence, choose one letter (A-H).
● Do not use each letter more than once.
11. Exports fell during the second year but then make a strong recovery in the final year.
12. Exports reached a peak at the beginning of the third year, while imports fell steadily through the whole period.
13. Imports remained fairly steady for the first two years before dropping dramatically in the third year.
14. Exports dropped in the first year but then increased considerably and overtook imports in the final year.
15. Imports rose over the whole period, while exports reached a peak at the beginning of the third year and then began to fall.
When our imports ______ our exports, we say we have a favorable trade balance; however, when our imports and exports are the other way round we say we have an unfavorable trade balance.
