Great changes have taken place in Beijing. In the past, the roads were {#blank#}1{#/blank#} /′nærəʊ/. Big families were crowded {#blank#}2{#/blank#} small houses. Many children couldn't get enough food and good education. People kept {#blank#}3{#/blank#} touch with their friends and {#blank#}4{#/blank#} /′relətɪvz/ far away mainly by letter or telegram. But now there are more and more ring roads. And the buildings are {#blank#}5{#/blank#} (tall). People can enjoy good {#blank#}6{#/blank#} /′medɪkl/ care. There are more food and clothes to {#blank#}7{#/blank#} /′sætɪsfaɪ/ people's needs. We can use telephones, cellphones, fax {#blank#}8{#/blank#} /mə′ʃi:nz/ and the Internet. We are so pleased to {#blank#}9{#/blank#} the changes in Beijing ourselves.

    We can't stop an earthquake，but we can do things to make sure they don't destroy (毁坏) whole cities. First，it is not a {#blank#}1{#/blank#}idea to build houses along lines where {#blank#}2{#/blank#}of the earth's plates (板块) join together. Second，if you think there {#blank#}3{#/blank#}be an earthquake，it is better to build houses on rocks， not on {#blank#}4{#/blank#}Third， you must make the houses as {#blank#}5{#/blank#}as possible. Weak buildings will {#blank#}6{#/blank#}down in an earthquake，but strong ones may stay up.

    Scientists are {#blank#}7{#/blank#}that one day an even bigger earthquake will hit the part around San Francisco. They call it “The Big One”. However，people today are still building more {#blank#}8{#/blank#}The population in and around San Francisco is {#blank#}9{#/blank#}ten times more than it was in 1906. This means that {#blank#}10{#/blank#}there is another earthquake，a great many houses and buildings will be destroyed.

    Pandas do not have many babies, maybe only one {#blank#}1{#/blank#} two years. The babies often die {#blank#}2{#/blank#} illnesses and do not live very long. Adult pandas spend more than 12 hours a day eating about 10 kilos of bamboo. Many years ago, there were a lot {#blank#}3{#/blank#} bamboo forests and pandas in China than there are now. But then humans started to cut {#blank#}4{#/blank#} the forests, and there was less bamboo for the pandas. Scientists say there are now fewer than 2,000 pandas living in the remaining forests. Another 200 {#blank#}5{#/blank#} live in zoos or research centers in China and other countries.

    Welcome to this short tour of London. In this square we are standing in the middle of Landon. Opposite is the National Gallery, a museum {#blank#}1{#/blank#} (介词) lots of famous paintings.

    Go along the red street to Buckingham Palace. The Queen {#blank#}2{#/blank#} (live) here.

    Turn left {#blank#}3{#/blank#} (连词) go to the Houses of Parliament and Big Ben. Opposite you can see  {#blank#}4{#/blank#} (冠词) London Eye. It takes you {#blank#}5{#/blank#} (metre) above the River Thames. You can see most of London  {#blank#}6{#/blank#} (介词) a clear day.

    Take the boat back along the river. Get off the boat and go past the station and walk along the street. Opposite is the old fruit and vegetable market. They {#blank#}7{#/blank#} (do not) sell fruit and vegetables now.

    There {#blank#}8{#/blank#}(be) stores and restaurants, and lots of street musicians. Tum left into King's Street, and go past the church. You're now back where you {#blank#}9{#/blank#} (start) at the square. Now you finish {#blank#}10{#/blank#} (you) tour.

    Homework is a big part of going to school. {#blank#}1{#/blank#}, you can do a few things to make homework less work.

    First, be sure you understand the task (任务). Write it {#blank#}2{#/blank#} in your notebook, and don't be afraid to ask questions about it. It's much easier to take a minute to ask the teacher during or after class {#blank#}3{#/blank#} to struggle (费力) to remember later that night! If you want, you can also ask how long you should spend in finishing the homework so you can plan your time.

    {#blank#}4{#/blank#}, try to do some homework at school. Many schools have study halls that are built to allow (允许) students to study. It's tempting (诱人的) to hang out (闲逛) with friends during study time. But the more work you can finish in school, the {#blank#}5{#/blank#} you'll have to do that night.

    Third, if you don't finish your homework during school, {#blank#}6{#/blank#} about how much you have left, and then plan your time. Most high school students have between 1 and 3 {#blank#}7{#/blank#} of homework a night. If it's a heavy homework day and it seems that you've got homework in every subject, you'll need to spend more time {#blank#}8{#/blank#} the homework.
