It’s important to teach children to create strong passwords(密码),and to remind them that passwords mustn’t be shared with anyone, not even best friends.
A strong password is a word that is as difficult as possible to guess because it looks like a set of random characters (随机的字符).
It’s wise to use the whole keyboard to mix a password with letters, numbers and symbols.A password of 14 characters or more may be much safer.
The following tips will tell you how to create a strong and safe password:
Tip 1: Think of a sentence that is easy to remember, but difficult to guess.For example: “ My son Peter is five years old and my daughter Tina is one year old.” The whole sentence is so long that it can’t be a password, so what you can do is to use the first letter of each word to make a new password that seems to be meaningless.That is “mspifyoamdtioyo”.
Tip 2: Make the password more difficult to guess by mixing big and small letters.One way to do this is to use big and small letters one after another.In this way this new password will be “MsPiFyOaMdTiOyO”.
Tip 3: Still using the sentence above, you can also add numers that are meaningful to you.As a result, the new password will be “Mspi5yOaMdTi1yO”.
Tip 4: Add punctuation(标点符号)and symbols to make the password much stronger.You may use symbols, numbers and punctuation to replace some letters which look similar.For example: “MsPi3y0@MdTi!y0”.(o=0, a=@, 1=!)

If you are not happy with China’s high Internet fees and slow speed, you are not alone.So is Premier Li Keqiang.On April 14, he said in a meeting that the government should speed up the Internet and lower the fees.
“The first question people ask at a new place is ‘Is there WI-FI’ because Internet service fees are so high,” said Premier Li.According to a recent survey by CCTV, the average cost of 1GB mobile Internet data per month in China is 100 Yuan, while it is only 60 Yuan in the US and 40 in Japan.
However, high prices don’t necessarily mean good service.The average Internet speed in China was 4.25Mbps(兆比特每秒)in late 2014.South Korea had the fastest average Internet speed-25.3 Mbps.People can download a 1 GB movie within 6 minutes in South Koreas, but in China it would take half an hour.
To improve Internet services, the key is to build more fiber(光纤) networks.Through them we can send text, pictures and videos globally in less than a second, which offer high speed Internet.Besides, the lack of market competition is another problems.Having more operators(运营商)besides China Unicom and China Telecom may lower the prices.

A recent survey showed that only 9 percent of teens in the United States smoke cigarettes.That’s down from 23 percent in 2000.While this is good news for the US's overall health, tobacco(烟草)use is still a problem.
