[单项选择] Pressure Cooker(压力锅) Safety
When you are cooking with a pressure cooker, you should learn a few common sense(常识) rules:
1. Never leave the cooker unwatched when it is in use.
2. Add sufficient liquid but never past the recommended fill point. Overfilling the cooker may block the vent pipe(排气孔) and cause the cooker to explode.
3. Set the cooking time. Too much time may overcook the food or too much pressure may build up in the cooker. Too little time will lead to undercooked food.
4. If you are new to pressure cooking, follow the cooking instructions carefully. Heat and time can either result in a great meal or a ruined one.
5. Never try to force a pressure cooker cover open. Allow the cooker to cool or run it under cool water before trying to open the cover.
6. Clean the cooker thoroughly after each use. Mild detergent(洗涤剂) and hot water work the best. Do not use stove ash or sand for they may damage the cooker. The gasket(密封圈) is best
A. a ruined meal
B. undercooked food
C. too little pressure
D. a blocked vent pipe

[单项选择]Just when you thought you knew a computer virus or worm when you saw one, several new infections that may fool you are gaining momentum on the Internet.
Most e-mail viruses require the victim to double-click open an infected attachment before they can wreak their havoc. But Badtrans-B and Atiz, two worms that were spreading quickly over the weekend and Monday, can launch themselves automatically when the recipient views or even just clicks on the subject line of an infected e-mail message using Microsoft’s Outlook and Outlook Express programs. October’s Nimda virus used a similar technique, which helped it spread further and faster than it otherwise might have. Computer users were safe from viruses as long as they didn’t download programs from the Internet or open e-mail attachments. But these days, viruses are as capable of getting into computers as Santa Claus is at getting down chimneys.
