When I was six, Dad brought home a dog{#blank#}1{#/blank#}(call) "Brownie". Brownie got along well with every member in our family. She would go to {#blank#}2{#/blank#}was sick and just be with them. We always felt much {#blank#}3{#/blank#}(good) when she was around.

    One day, as I was getting her food, she{#blank#}4{#/blank#}(bite) a hole out of one of Dad's shoes. I scolded her,{#blank#}5{#/blank#} (tell) her what she did was wrong. She looked down at the ground and then went and hid. I saw tears in her eyes.

    Brownie went everywhere with us. People would stop and ask if they could pet her. Of course she'd let anyone pet her. She was just the most lovable dog. There were many times{#blank#}6{#/blank#}we'd be out walking and a small child would come over and pull on her hair. She never barked or tried to get away. The{#blank#}7{#/blank#}(fun) thing was that she would smile. This frightened people because{#blank#}8{#/blank#}thought she was showing her teeth. Far from the truth, she loved everyone.

    Now many years have passed since Brownie{#blank#}9{#/blank#}(die) of old age. I still miss the days when she was{#blank#}10{#/blank#}us.

    I got a new job in Catholic University in Washington. In addition to a good chance, I {#blank#}1{#/blank#}(offer) a new flat to live in. One summer vacation, apart {#blank#}2{#/blank#} going to the park, I had not been outside my flat so as{#blank#}3{#/blank#} (do) an experiment about a disease. The {#blank#}4{#/blank#} (result) of the experiment were {#blank#}5{#/blank#} (value) to me and they would contribute to the success of my research. It is really difficult to draw {#blank#}6{#/blank#}conclusion without enough evidence. I felt quite puzzled,{#blank#}7{#/blank#} even made me doubt that the experiment would make sense.{#blank#}8{#/blank#} (gradual), I was not enthusiastic about it. After all, too much hard work and too little rest led to illness. One night, I went out to attend a lecture by a famous philosopher.{#blank#}9{#/blank#} (inspire) by him, I went back to continue the experiment and eventually got the expected result. How happy I was! The next day, I proudly announced that the disease was {#blank#}10{#/blank#}control.

    Nowadays, millions {#blank#}1{#/blank#} lonely singles are now going online instead. The World Wide Web is quickly becoming{#blank#}2{#/blank#} world's most popular matchmaker(媒人).

    Singles are flocking(涌向) to the Internet {#blank#}3{#/blank#} (main) because their busy lifestyles leave them little time to look for a significant other. Using dating sites(约会网址) is quick and convenient. Many singles say the regular dating scene {#blank#}4{#/blank#} (lead) them from one bad experience to {#blank#}5{#/blank#} and are ready to try something else. Dating sites also make {#blank#}6{#/blank#} easy to avoid someone {#blank#}7{#/blank#} you are not interested in. In the real world, {#blank#}8{#/blank#}, ignoring someone you don't like can be difficult.

    Despite all the advantages, online dating also presents its own set of problems. People aren't always those who they declare to be in their online {#blank#}9{#/blank#} (describe). Safety is another concern. You are just {#blank#}10{#/blank#} (like) to find a criminal online as you are Mr. Or Miss Right.

    So why has English changed {#blank#}1{#/blank#} time? Actually all languages change and develop {#blank#}2{#/blank#} cultures meet and communicate with each other. At first the English spoken in England between about AD 450 and 1150 was very different from the English spoken today. It was based more on German {#blank#}3{#/blank#} the English we speak at present. Then gradually between about 800 and 1150, English became {#blank#}4{#/blank#} (little) like German because those {#blank#}5{#/blank#} ruled English spoke first Danish and later French. These new comers {#blank#}6{#/blank#} (rich) the English language and especially {#blank#}7{#/blank#} (it) vocabulary. So by the 1600s Shakespeare was able to make use of a wider vocabulary than ever before. In 1620 some British {#blank#}8{#/blank#} (settle) moved to America. Later in the 18^th century some British people {#blank#}9{#/blank#} (take) to Australia too. English began to be spoken in both countries. Today, {#blank#}10{#/blank#} number of people learning English in the world is increasing rapidly.
