A semiconductor is an electric conductor with resistivity in the range between metals and insulators, in which the electrical charge carrier concentration (увеличивается) with increasing temperature over some temperature range.
The resistivitiys of semiconductors and insulators (уменьшается) rapidly with rising temperatures, while those of metals (увеличевается) relatively slow.

Answer 1

A transistor is an active semiconductor device with three or more electrodes.By active (подразумевается is meant) that the transistor is capable of current gain, voltage amplification and power gain. A transistor is an electronic device in which electronic conduction (производится is performed) within a semiconductor.
A semiconductor is an electric conductor with resistivity in the range between metals and insulators, in which the electrical charge carrier concentration (увеличивается grows) with increasing temperature over some temperature range.
The resistivitiys of semiconductors and insulators (уменьшается falls) rapidly with rising temperatures, while those of metals (увеличевается goes up) relatively slow.
