The adobe dwellings(土坯房）{#blank#}1{#/blank#}(build) by the Pueblo Indians of the American Southwest are admired by even {#blank#}2{#/blank#}most modern of architects and engineers. In addition to their simple beauty, what makes the adobe dwellings admirable is their {#blank#}3{#/blank#}(able) to “air condition” a house without {#blank#}4{#/blank#}（use）exact equipment. Walls made of adobe take in the heat from the sun on hot days and give out that her{#blank#}5{#/blank#}（slow）during cool nights，thus warning the house. When a new day breaks, the walls have given up their heat and are now cold enough {#blank#}6{#/blank#} (cool) the house during the hot day: {#blank#}7{#/blank#} the same time, they warm up again for the night This cycle {#blank#}8{#/blank#} (go) day after day: The walls warm up During the day and cool off during the night and thus always a timely offset（抵消）for the outside temperatures. As {#blank#}9{#/blank#}(nature) architects, the Pueblo Indians figured out exactly{#blank#}10{#/blank#}thick the adobe walls needed to be to make the cycle work on most days.

    Our ancestors（祖先）made the old saying that friends{#blank#}1{#/blank#}(be) like wine-the older,the better.Because of that, many people think old friends to be{#blank#}2{#/blank#}(important) than new ones.For example,if two pieces of advice are given to solve a problem,one from a new friend and the other from an old friend,people always prefer to choose the latter one,{#blank#}3{#/blank#}the new friend's advice may be better.

    {#blank#}4{#/blank#}(disagree) with the old saying,I believe that new friends are not{#blank#}5{#/blank#}(necessary) worse than old friends. Why?Because the{#blank#}6{#/blank#}(long) of time cannot tell whether your friendship is better or not.

    Once you call someone friend,he must be a person who is{#blank#}7{#/blank#}(rely) and whose interests are in common with{#blank#}8{#/blank#}(you).Maybe a friend's outside look{#blank#}9{#/blank#}(change) all the time,but the inside characters of him and his interests won't change at all.It is just these unchangeable characters and interests that make him a friend to you.{#blank#}10{#/blank#},there is no difference between old friends and new ones on this point.

    The Olympic Games are the {#blank#}1{#/blank#}(big) sports meeting in the world. There are two kinds of Olympic Games. One is the Summer Olympic Games, and the other is the Winter Olympic Games. {#blank#}2{#/blank#}of them are held every four years on a regular {#blank#}3{#/blank#}(base). All countries can take part if their athletes have reached the {#blank#}4{#/blank#}(agree) standard to the games. In the past women were not allowed to take part in the Olympic Games. Nowadays, women have a chance {#blank#}5{#/blank#}(play) an important role in the great games. Because of so many athletes, a special village is needed to build for {#blank#}6{#/blank#} to live in, {#blank#}7{#/blank#}(include) a main reception building, several stadiums for competitions, a large swimming pool, and seats for audience {#blank#}8{#/blank#}watch the games. It is a great honor to host the Olympic Games. In addition, for many countries it's just as much competition to host the Olympic Games {#blank#}9{#/blank#} to win Olympic medals. Nowadays, the olive wreath has been replaced by medals. But it's still about being able to run {#blank#}10{#/blank#}(fast), jump higher and throw farther.

    As populations increased in large cities in {#blank#}1{#/blank#} nineteenth century, building subway lines was a way {#blank#}2{#/blank#}(move) people from one area of a city to another quickly and efficiently. The first major subway system, the London Underground, {#blank#}3{#/blank#}(start) in 1873 using steam trains. Subways caught on quickly in London. From 1896, it was changed in favor of an electrical system. Today's subways around the world now work on {#blank#}4{#/blank#}(electrical). Passengers can rely on the regular schedule of subway trains while {#blank#}5{#/blank#}(avoid) traffic on busy city streets.

    Two of the world's earliest subways were built in Paris and New York. When the Paris Metro opened on July 19, 1900, citizens were proud of the {#blank#}6{#/blank#}(impress) and beautifully decorated station entrances.{#blank#}7{#/blank#} the first New York subway consisted {#blank#}8{#/blank#} only 14.5 kilometers of track in 1904, today, it is the world's largest subway system.

    Today, subways are still popular with passengers. The Tokyo subway is the {#blank#}9{#/blank#}(busy) in the world, with 3.2 billion riders a year. Close behind {#blank#}10{#/blank#}(be) subways in Moscow(2.4 billion), Seoul (2.1 billion), and New York City (1.6 billion).

    According to the report, Tian'anmen Square will enter the 5G era（时代）. This also means the Tian'anmen Square {#blank#}1{#/blank#} (become) a "5G smart square" in the near future. 5G networks not only have better signals and {#blank#}2{#/blank#} (fast) download speeds, but also have a far-reaching impact on large tourist attractions. In addition to meeting the needs of high-speed internet access, 5G network can also support 4K HD video calling, so as to bring better experiences for the general public and tourists.

    She looks like any other schoolgirl, fresh-faced and full of life. Sarah Thomas is looking forward to the challenge of her new A-level course. But unlike her school friends, 16-year-old Sarah is not spending half-term rest. Instead, she is earning £6500 a day as {#blank#}1{#/blank#}model in New York.

    Sarah {#blank#}2{#/blank#}(tell) that she could be Britain's new supermodel{#blank#}3{#/blank#} (earn) a million dollars in the next year. Her father Peter, 44, wants her to give up school to model full-time. But Sarah, {#blank#}4{#/blank#}has taken part in shows along with top models, wants to prove that she has brains as well as beauty. She is determined to carry on with her{#blank#}5{#/blank#} (educate).

    She has turned down several {#blank#}6{#/blank#} (invite) to star at shows in order to concentrate on her studies. After school she plans to take a year off to model full-time before going to university to get a degree {#blank#}7{#/blank#}engineering or architecture.

    Sarah says, "My dad thinks I should take the offer now. {#blank#}8{#/blank#}at the moment, school comes first. I don't want to get too {#blank#}9{#/blank#} (absorb) in modeling. It is certainly fun that the lifestyle is a little{#blank#}10{#/blank#} (real). I don't want to have nothing else to fall back on when I can't model any more."
