VI. Прочитайте и устно переведите на русский язык весь текст. Перепишите и письменно пере-

1. A snowflake originates from countless water molecules that come together in small groups as a result of
a weak attractive force between oxygen and hydrogen atoms. The same forces organize the groups into a frozen
molecular crystal, a perfectly organized lattice of molecules. Finally, several molecular crystals join to form a
snowflake. Scientists have realized for some time that the forces that assemble molecules into natural crystals
can be used to produce a variety of important materials. They have determined the structure of more than
90,000 different molecular crystals.
2. In recent years, researchers have studied how molecules organize themselves to form crystals in the
hope of better understanding what types of molecules and what conditions will produce molecular crystals with
unusual and useful properties. Scientists are aware that the material properties of a crystal depend in large part
on the organization of the molecules in the crystal, yet they know little about the factors controlling the assem-
bly of such crystals.
3. Synthesizing a molecular crystal is similar to designing a building. Before construction can begin, the
architect must specify the shapes and sizes of the girders and the number and placement of the rivets. Similarly,
to produce new molecular crystals, chemists must choose molecules of the appropriate sizes and shapes and se-
lect the molecular forces that will hold the crystals together. A chemist can normally find many molecules of
various shapes and sizes, but the task is to find ones that assemble in a predictable manner.
