You may use banknotes every day. But did you know that there is a lot of science behind the money? {#blank#}1{#/blank#}

    Australia was the first country to use polymer(聚合物）banknotes in 1988. {#blank#}2{#/blank#}

They can stop water from making them wet. They are also cleaner because bacteria don't grow easily on them.

Now, the Australians have improved their banknotes again by creating a new 5-dollar note. The new one has a clear window in the middle in which there are pictures of an Australian bird and a building. {#blank#}3{#/blank#}

    Tilt (倾斜）the note a little and you will see the bird flapping its wings as if trying to fly away. Turn the note from side to side and you will notice the building come to life and spin. While these features are impressive and entertaining, that was not the reason why the Australian Government spent ten years perfecting them. Their primary purpose was to make it impossible to fake a banknote.

    {#blank#}4{#/blank#} The new $ 5 bill now has a raised bump alongside the two long edges, enabling the blind or those with limited vision, to quickly determine its value.

The Australian government will give the new 10-dollar note the same features in a year's time. {#blank#}5{#/blank#}

A. Note makers still have a long way to go.

B. Other notes will have them in the future.

C. The magic of the new features lies in them.

D. They have many advantages over paper notes.

E. The new Australian 5-dollar note is a good example.

F. The new note is also the first touchable Australian banknote.

G. Their material and pattern set them apart from ordinary banknotes.

Exercise regularly

    {#blank#}5{#/blank#} The afternoon or the evening is a pretty popular time for people to work out. It can sometimes be difficult if you have a full-time job, but things can usually be rearranged a bit.

    It's good to have friends that we can talk to and share our thoughts and opinions with.{#blank#}1{#/blank#}But recently, it seems that many of us have been developing a new relationship with a mystery person that we'll never meet.

    These people are virtual (虚拟的) assistants. They are pieces of software that we can talk to and they can talk back to us. An example is Apple's Siri. They might be on your phone or computer or even a smart speaker in your home. {#blank#}2{#/blank#} Instead of typing on a computer keyboard, we can now speak and a voice will answer. {#blank#}3{#/blank#} Tom Hewitson is one of them. He told the BBC, “Now, computers are an active participant in the conversation and in guiding you to make the right decision.” So he's saying this cutting-edge(尖端的) technology has the ability to think for itself and make its own decisions. {#blank#}4{#/blank#} Will it stop us using our own brains and will we lose the ability to write things down or type? They are certainly clever, helping you to book train tickets, give you the latest weather news or even tell you a joke.

How to Meet New People

    It is easy to find a place where people gather. But once you're in a room full of people, then what? The trick is finding a way to approach someone and get them talking to you.

    Prepare to meet new people before you arrive. {#blank#}1{#/blank#}. Don't think in terms of yes or no questions. You should consider questions that will allow the person to contribute more than a one-word answer to the conversation.

    Arrive at your event or place. Don't panic when you walk in the door. Take your time and look over the room. If this is a classroom, take a seat and look around the room. {#blank#}2{#/blank#}, take time to enjoy the art while looking at the people. Don't rush into talking to someone. You have time, so just get a feel for the group.

    Approach someone. {#blank#}3{#/blank#}. But remember, if the person is at the event alone, they may also be shy and try to break out and meet people. You need to make them feel comfortable by chatting with them.

    {#blank#}4{#/blank#}. Keep them talking and talk yourself—remember  conversation goes in two directions. You may have a couple of awkward moments, but if you have a few items planned to talk about, you'll find that they'll start adding their own questions and information to the conversation.

    Don't forget to ask them for a friendship follow-up. {#blank#}5{#/blank#}, try asking your new friend if they'd like to go to another event with you. If it is a repeat event, such as a class, try asking them if they'd like to meet for coffee before the next class to study the material.

B. If this is an art show
