Sonora wanted to honor (对……表示敬意) her father who raised (抚养) six children after his wife died. In 1924, President Calvin Coolidge supported (支持) the idea of a national Father’s Day. In 1966, President Lyndon Johnson declared (宣布) the 3rd Sunday of June was Father’s Day in the United States.Today, Father’s Day is as popular as Mother’s Day.

However, the idea of honoring Dad with a special day seems to be similar.Believe it or not, flowers are a part of Father’s Day tradition.

communications easier.But the telephones were only fixed in post offices.People had to go there to make calls to faraway people and the fees were very ter，a cellphone was developed in 1973 in America.It was one of the most useful inventions.People can use cellphones to communicate with others much more easily.They can take them anywhere tomake private calls，even vision calls (可视电话)．Cellphones have many other functions，such as sending messages，taking photos and reading online.TVThe first TV set was invented by an English scientist，John Baird，in 1926.The invention helped people watch films at home instead of going to the cinema as before.At first，TV sets only broadcast black-white pictures.Several years later，colored TV sets made the pictures lively.However，they were heavy and thick，so it was difficult to move them.Then，digital TV sets came into being.They are light and thin.Many TV programs are available(可获得的)at any time.At present，people can use the IPTV(网络电视)to record and replay programs.ComputerThe first modern computer was invented in America in 1946.It was as big as a room.It improved the speed and exactitude of calculation (计算)．In the 1950s，desktop computers were invented in the same country.They became smaller and could be put on the desk.Since then，they have become very important in many fields of work and leisure.Before the 1970s，the computers were single.It was the Internet that joined the computers into a big family，so they could share information with one another.Around 1985，laptops were developed in Japan.They were much smaller and could be put on people's laps.They were light and easy to take.26．The first cellphone was invented________．A．in 1876 B．in 1926C．in 1946 D．in 197327．People could watch films ________before

Internet are playing an important part in our life.Some people even say they can't live without them．We usually need to set passwords(密码) when we use computers and the Internet.But not all the passwords are safe.We should learn how to make safe passwords.How can you make your computer and Internet passwords safe？Experts have some tips for you.You'd better remember the tips and they are useful for you.Here are the tips.First，make your passwords out of capital(大写的) letters.It will be difficult for others to get into your account(账户)．It only takes a hacker(黑客) 10 minutes to work out a six-letter password which is made up of small letters.But the same password in capital letters takes hackers 10 hours to work out.Second，add numbers or symbols to your passwords.It may be much safer.Sometimes such passwords are not easy to remember，but they are really safe.Third，never use personal information for passwords and use different passwords for different accounts.Experts say that a user should change his or her passwords every 90 days.In that way，hackers won't guess your passwords.31．The underlined word “them” re fers to(指的是)“________”．A．the passwordsB．computers and the InternetC．the capital lettersD．the accounts32．If you set your password with six capital letters，a hacker may spend ________ working it out.A．10 minutes B．10 hoursC．one day D．a week33．You should change
