Exercise 3

Translate the following sentences paying attention to tenses.

1.There is a growing scientific evidence that prolonged exposure to some kinds of radio waves does cause at least low-level changes in the movements, working and possibly structure of molecules and cells in living tissue. 2. Naturally, optoelectronics engineers would love to make VCSELs from silicon, but the material does not emit light easily. 3. For 50 years hard disks have acted as relatively dumb devices, simply serving as storing blocks of data. 4. The drive manufacturers have to some extent become victims of their own success. 5. In both ATA- and SCSI-based systems, computers commonly divide a data file into a set of so-called logical blocks whose size ranges from 512 bytes to 4096 bytes and up. 6. The person who comes up with application thinks differently than the scientist who lays the foundation. 7. The principal application of any sufficiently new and innovative technology always have been and will continue to be applications created by that new technology. 8.
