Pocket Tape-Recorders“Family and Home Magazine”test what’s on the market now.

1)Pearlcorder S702 $64

This 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: 30 minutes per side. Weight: 240g.

2)Sony M9 $49.95

Small and very good looking, Sony’s latest offering scored most for 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. Doesn’t switch off automatically but a red light shows if the machine is still running.

Tape length: 60 minutes per side. Weight: 195g.

3)Sony M400 $115

　　Lots of little control buttons that make a noise and are difficult to use. Recording was good but machine noise lost points. Tape counter and automatic switch-off when tape has finished recording or rewinding are useful Tape length: 60 minutes per side. Weight: 230g.

　　　　 4)Imperial OEM. MC $29.95

　　 Cheap and simple compared with the rest, but recording was good as long as there was 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.

5)Philips 585 $80

　　　 Handsome 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.

Do dogs understand us?

　　　　　　　　　　　　　 Be careful what you say around your dog. It might understand more than you think.

　　　 A border collie(柯利狗)named Rico recognizes the names of about 200 objects, say researchers in Germany. The dog also appears to be able to learn new words as easily as a 3-year-old child. Its word-learning skills are as good as those of a parrot or chimpanzee(黑猩猩).

　　 In one experiment, the researchers took all 200 items that Rico is supposed to know and divided them into 20 groups of 10 objects. Then the owner told the dog to go and fetch one of the items and bring it back. In four tests, Rico got 37 out of 40 commands right. As the dog couldn’t see anyone to get clues(线索), the scientists believe Rico must understand the meanings of certain words.

　　　 In another experiment, the scientists took one toy that Rico had never seen before and put it in a room with seven toys whose names the dog already knew. The owner then told Rico to fetch the object, using a word the dog had never heard before.

　　　 The correct object was chosen in seven out of 10 tests, suggesting that the dog had worked out the answer by process of elimination(排除法). A month later, Rico remembered half of the new names, which is even more impressive.

　　　 Rico is thought to be smarter than the average dog. For one thing, Rico is a border collie, a breed(品种)known for its mental abilities. In addition, the 9-year-old dog has been trained to fetch toys by their names since the age of nine months.

　　　 It’s hard to know if all dogs understand at least some of the words we say. Even if they do, they can’t talk back. Still, it wouldn’t hurt to sweet-talk your dog every now and then. You might just get a big, wet kiss in return!
