Many people believe that yellowing and wetness are the greatest enemy of stamps. In fact, stamps are afraid of not only wetness, but also light and dirty things. People protect their stamps in several different ways.

 To protect stamps,we should never touch the stamps with our hands.This avoids moving dirty things onto them. Stamp tweezers (镊子) should be used in all conditions.

 Stamps are printed things. The colour will slowly disappear if the stamps are put in the light for a long time. So we should not put stamps in the light for long. Direct sunlight must be avoided as well.

 Wetness is an important  problem for stamps. Some  collectors  will put stamps  in separate plastic (塑料) bags. However, it is possible that some stamps have taken in some water from the air before they are put into the plastic bags.Stamps yellow easily and rapidly after they take in wet air.To protect the stamps, some people also put the stamps into a special room which has a machine to  keep the air cool and dry. However, not many people can afford that.

 To keep stamps, stamp collectors usually put them under plastic covers. It is a common and simple way. This helps because the plastic cover keeps the stamps off the wet air. It also stops the fingersfrom touching te stamps.

 Some  collectors  prefer  to  store  stamps  inside  a  plastic  box  with  desiccants  (干燥剂).However, we should take care not to let the stamps. touch the desiccants. On top of that, don't  take your stamps out on a wet day.

    My challenge for you is this: to read a book for 15 minutes a day. Let me explain where the challenge came from.

    I have many things in common with my dad, like music taste and sense of humor, but sadly reading isn't one of them. I can happily spend a whole day reading a book. {#blank#}1{#/blank#} He reads e-mails, websites and papers for work, but not books. He is a busy person, with a short attention span, so I think that sitting down to read for just 15 minutes a day is a good way to introduce him to reading. Giving yourself a goal or challenge is a good way to change a habit or achieve something, so why not try to develop a new habit of reading?

     {#blank#}2{#/blank#} Everyone is different and has their own interests, but I think there are lots of benefits of reading, which screen-based activities (games, films,

TV) don't have.

     {#blank#}3{#/blank#} Looking at screens can cause tire eyes, and you should avoid looking at screens for a long time.

    Another thing I love about reading is being transported to another world. {#blank#}4{#/blank#} So you go to bed. Because you think more about the world of the book, rather than the real world and the problems you have during the day, so you can truly relax.

    I also love people. I enjoy hearing what people are doing and finding out what people think.{#blank#}5{#/blank#} It also teaches me to see things from other people's point of view, and understand other people's decisions or opinions.

    So give it a try! Include 15 minutes of reading in your daily schedule and see the difference you can make.

A. Firstly, it's better for your eyes.

B. But my dad can't read a book for longer than 5 minutes.

C. I often forget the time or things that are going on around me.

D. Reading ten thousand books is like travelling ten thousand miles.

E.  Reading gives me the chance to get to know hundreds of new people.

F. You can download free e-books online and read them on your computer.

G. I know lots of people would rather relax at the computer or in front of the TV.

House fires cause many deaths each year and a large number of these fires are unfortunately set by children.{#blank#}1{#/blank#}Kids must understand that they'd better not play with fire. You should keep matches and lighters out of their reach.

{#blank#}2{#/blank#} The main job of such an alarm is to protect you while you're asleep. You should have a smoke alarm outside each bedroom and on each floor of your home. You ought to have two plans for getting out of your house if there is a fire and practise these plans in the dark with your family.

A smoke alarm warns you of the danger. {#blank#}3{#/blank#}Take action immediately. When you come to a closed door, check it with the back of your hand. If it feels hot, there may be smoke or fire behind the door, so take care. Once you are out of your house, call the fire department from a neighbor's house. If a family member or a pet is caught inside, you shouldn't go back in. Firemen know how to perform rescues safely.

{#blank#}4{#/blank#} Change the batteries at least once a year. You should use the test button each month to see if the alarm and batteries are still working. A smoke alarm lasts about ten years. You ought to change it even if it seems to be working.
