1 . Winter is often quite cold, which often makes us stay indoors more instead of heading out to exercise. Worse still, there are many viruses(病毒) doing their best to make you sick. And sneezing, coughing and nose blowing make the rooms a habitat for viruses.     1    Touching a doorknob or shaking a hand may make you get sick. Although it may sound terrible, there are still some things you can do to avoid viruses. Here are several simple tips to stay healthy in winters.

Wash your hands. You pick up viruses everywhere and they live on your hands, so wash your hands and do it often.     2    . But if that’s not available, use an alcohol-based hand sanitizer (消毒杀菌剂).

    3    :Avoid touching your eyes, nose and mouth with your hands. That’s one way viruses can get into your body.

Get the flu shot(疫苗).     4    , but getting the flu shot lowers your chances of getting the flu. For example, getting the flu shot last year resulted in a 34% lower risk of coming down with the flu.

Avoid sick people.     5     Viruses spread very easily through the air, so keep at least six feet between you and the sneezing, sniffling and coughing person.

3 . To help you understand what 5G is, and what it means to you, we’ve put together a handy guide here.

What is 5G?

    1    At its most basic level, 5G will be used to make calls, send texts, and to simply get online. But it’s going to be significantly faster than previous generations, and could open the door up to a range of exciting new uses.

    2    

5G will use new higher radio frequencies to send out data, which are less cluttered(挤了)and carry information much faster. While these higher bands(频段) are faster, they don’t carry information as far. That’s to say, smaller multiple input and output antennas (天线)will be used—promoting both signals and capacity(容量).    3    

Why is it better than 4G?

5G is expected to be faster than 4G, with some firms claiming it could be as much as 100 times quicker. The fastest 4G networks can deliver 传输)peak(峰值)download speeds of around 300 Mbit/s.    4    In real life, this could allow you to download a full HD film in less than 10 seconds!    5     It means there will be very little—if any—delay when you carry out tasks on a device(设备). While this will help improve things like gaming experiences, it could also pave(为…铺平道路)the way for safer self-driving cars—in which even a short delay could be life-saving.

Finally, 5G will have a larger capacity, meaning networks will be able to deal with several apps at once. Generally, this should mean that devices have a faster, more stable connection.

10 . Teenagers’ fitness is now a major concern，and physical exercise is very important. It reduces stress and improves fitness. Exercise makes your body strong，and helps you to keep the right body weight. Sports scientist Dr. Helen Lopez offers the following advice to teenagers：“First，you need to find out your present level of fitness. Then you can design a programme that will help you become healthier.”

Dr. Lopez suggests that there are three levels of fitness that need a change of lifestyle.“Overweight”means that the person gets very little exercise and often has a serious weight problem. “Inactive” means that the person does not join in many physical activities，but is not seriously overweight.“Active”refers to people who take part in sports and other physical activities，but do not have a high fitness level.

According to Dr. Lopez，overweight teenagers should work out to keep healthy.“Ride a bike，play volleyball or basketball for a while，and go for a twenty­minute walk each day. All these will help to burn calories.”Inactive teenagers should do similar activities, but add some bending and stretching exercises, such as push­ups and sit­ups, starting with twenty of each a day.“Inactive people can take a little more exercise than overweight people because their bodies are stronger，”Dr. Lopez said. The same rule applies to active teenagers.

Dr. Lopez suggests one hour a week or more on running and other forms of intensive exercise，together with fifteen minutes a day spent on stretching and bending activities.“These are really important in order to prevent injuries,” Dr. Lopez said. Some weight­training and other body­strengthening exercises could also be planned in the programme in order to increase the person’s strength.
