The following are the results of the tests done by “Family and Home Magazine” on some Pocket Tape-Recorders on the market now.  Pearlcorder S702 $64This simple model at the bottom of the Olympus range scored the most points for its excellent quality of recording. Background noise hardly affects the sound and recording from a pocket is perfectly possible, but it doesn’t turn off automatically.Tape length: 30minutes per side. Weight: 240g.Sony M9 $49.95Small and very good looking, Sony’s latest offering scored most for its appearance. Sounds clear, but there is slight machine noise. The big control buttons are a great improvement on some of the complicated little controls on other tape-recorders. It doesn’t switch off automatically, but a red light shows if the machine is still running.Tape length: 60minutes per side. Weight: 195g.Sony M400 $115Lots of little control buttons that make a noise are difficult to use. Recording is good but machine noise loses points. Tape counter and automatic switch-off when tape has finished recording or rewinding are useful.Tape length: 60 minutes per side. Weight: 230g.Imperial OEM MC7 $ 29.95Cheap and simple compared with the rest, but recording is good as long as there is no background noise. Use only its own-make of cassette. No light to show it is on; no fast-forward button and the record button makes a loud noise.Tape length: 30 minutes per side. Weight: 285g.Philips 585 $80Handsome and simple to use, but recording is very poor at more than the recommended distance of 5 cm-designed for dictation. No recording light.Tape length: 15 minutes per side. Weight: 220g.小题1:The machine that produces the best recording with the least unwanted noise is _____.
