Exercise 5. Translate at sight.

Aluminium is the most abundant metal, but it was not used until a century ago because it is active chemically and difficult to extract. Like iron it is soft, but in contrast to iron and steel, aluminium is very light and more resistant to corrosion. These qualities make it useful for airplanes, trains, automobiles, rockets, and for some constructional purposes.

In the 1940s, magnesium emerged as an important metal. Although it is less abundant in the earth, more chemically active, and harder to extract than aluminium, it is present in sea water and that means there is almost an endless supply of it.

In the space age, the extraordinary properties of titanium have made it the new wonder metal. Lighter and stronger than steel, it is more resistant to corrosion and able to withstand heat.

The remaining major metals are sodium, potassium, and calcium, all too active chemically (they react violently with water) for use in construction.
