[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. Antivirus software maker McAfee, a division of Santa Clara, Calif.’s Network Associates,

[不定项选择题]共用题干 Energize Yourself and Your Family

Being healthy and active can help give you the energy to keep up with the demands of your busy life,take better care of yourseff,and be there for the people who depend on you.
If you are overweight and inactive,you are more likely to get Type 2 diabetes,heart disease, high blood pressure,stroke and certain forms of cancer. You may improve your health if you move more and eat better!Here are some tips on how to get moving and eat well even when your life is busy.
Try to do at least 30 minutes of moderate-intensity physical activity (like brisk walking) on most days of the week.It is not as hard as you may think,and you do not have to do the whole 30 minutes at one time.Give up the typical excuse such as"I don't have time for physical activity". You can"sneak"it into your day,a few minutes at a time.Get started by making small changes in your daily routine,for example,get off the bus or subway one stop early and walk the rest of the way. You do not have to do your entire workout in one block of time.Break it up一taking three 10- minute walks during your day may be easier than taking one 30-minute walk.
Physical activities do not have to be chores.You can make them fun.Do things you enjoy,like walking,dancing,swimming,or playing sports.Walk or take an exercise class with a friend or a group.Be active with your kids-ride bikes or toss a softball.
It may be hard to eat healthy if you do not have time to cook or your kids want fast food.Here are some ways that you and your family can eat better. Eat breakfast every day.Try a whole-grain cereal like raisin bran with fat-free or low-fat milk,or whole-wheat toast spread with jam. Enjoy some fruit with your breakfast too.Teach kids that healthy foods taste good.Choose fat-free or low-fat milk,yogurt,and cheese instead of full-fat dairy products.Choose whole-grain foods like whole-wheat bread,oatmeal,and brown rice more often than refined-grain foods,like white bread and white rice.Snack on fruits and vegetables. Keep a bowl of fruit on the table,bags of mini carrots in the refrigerator,and boxes of raisins in the cupboard.Do not keep a lot of sweets like cookies,candy,or soda in the house.
Set goals.Move at your own pace.Celebrate your successes.Allow for setbacks.Let your family and friends help you.And keep trying一you can do it! If you do not have time to cook,you will not be healthy.
