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 $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: 30minutes per side. Weight: 240g.
Sony M9   $49.95
Small 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  $115
Lots 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 $ 29.95
Cheap 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 $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.
【小题1】The machine that produces the best recording with the least unwanted noise is _____.

A.Pearlcorder S 702B.Sony M9C.Sony M400D.Imperial OEM MC7

We are now living in an information world that TV, cell phones and the Web are wide used. It seems that many people can not enjoy them without them. However, if I had to give up one of them, I will turn off the TV rather than switch off my cell phone and cut off the Internet. I could do without TV because few show take my fancy and there’re too many commercials. Besides, most programs on the TV are also available elsewhere. As for cell phones and the Web, they are more necessarily to me. I need a cell phone to keep touch with my friends and family, and almost all information can be gather on the Internet.

It is common to have difficulties sleeping during the day. Humans are naturally wired to sleep best at night and be awake during the day. However, modern work schedules require some people to try to accommodate the unnatural schedule of shift(轮班)work — being awake at night and sleeping during the day.

In order to make this adjustment, you need to pay special attention to your sleep environment and your preparation for sleep. If shift work is a necessary part of your work life, here are some suggestions that may help.

Arrange to sleep uninterrupted in a quiet, dark room. This means you may have to turn off or unplug your phone, hang darkening curtains on the windows or wear a sleep eye mask, and train your family and friends to leave you alone while you sleep.

Fit in a nap(小睡). When your daytime sleep period is too short, taking a short nap of less than 30 minutes just before work or on a break has been shown to improve alertness and enhance performance.

Develop and follow a sleep routine. It's best if you go to sleep and wake up at the same time every day. Try not to vary this too much on weekends. Your body likes routine.

Take extra care to make healthy choices. You may be tempted to reach for unhealthy foods or nicotine to stay awake or alcohol to try to sleep. But ultimately these choices are more harmful than helpful.

If you have tried all these things and are still having problems getting enough quality sleep during the day, talk to your doctor or a sleep specialist. Sometimes medications(药物治疗)may be helpful and safe. In other cases, there may be an underlying sleep disorder that needs to be addressed.
