    People often have trouble {#blank#}1{#/blank#}（get）used to a new culture. They are usually curious {#blank#}2{#/blank#} they first arrive in a foreign country. However, if they stay for {#blank#}3{#/blank#} long time, they may start to feel different {#blank#}4{#/blank#} (stage) of culture shock. They can feel lonely or sad because they can't deal with the local people. How {#blank#}5{#/blank#} (quick) people get used to culture differences may depend {#blank#}6{#/blank#} the way they learn. That's a problem if they can't speak the language. On {#blank#}7{#/blank#} other hand, some can study the situation and make good guesses about the culture. When they finally begin {#blank#}8{#/blank#} (understand) some of the language and make some new friends, they will gradually enjoy {#blank#}9{#/blank#} and feel {#blank#}10{#/blank#} (comfort).

    July 20, 1969 was an important day. Two {#blank#}1{#/blank#} (美国) astronauts planted the first human footstep on the moon. {#blank#}2{#/blank#} (他们的) names were Armstrong and Aldrin. They went into a spaceship whose name was Apollo. As Armstrong reached his left foot {#blank#}3{#/blank#} （touch） the moon's surface, he said, "That's one small step for a man, but one big leap for mankind."

    {#blank#}4{#/blank#} two hours and twenty-one minutes, the man carefully at first and then {#blank#}5{#/blank#} (勇敢), walked on the moon, {#blank#}6{#/blank#} （take）photos and picking stones.

    After eight {#blank#}7{#/blank#} (day) stay in space, Apollo returned to the earth successfully. People everywhere were {#blank#}8{#/blank#} (excite) by this moon trip. "This is the {#blank#}9{#/blank#} (伟大) week in the history of the world since the Creation(创世)," President Nixon told the travelers. "{#blank#}10{#/blank#}（多亏，由于）what you have done, the world has never been closer together before."

When talking about our bodies, we often forget our skin. Actually, our skin is very important, too. It keeps us{#blank#}1{#/blank#}(inform) of the outside world--{#blank#}2{#/blank#}it is hot or cold, wet or dry.

Try this: pull up the skin from the back of your hand and then let {#blank#}3{#/blank#}go. What happens?

The skin goes back to its first position, which means that skin is elastic (有弹性的).

Our skin seems to be very thin, but it {#blank#}4{#/blank#} (make) up of two layers. The top layer is the one we wash every day. Do you know that this part of skin is dead? However, it is still very important because it serves as{#blank#}5{#/blank#} (protect) against dirt and disease.

Skin has millions of tiny holes called pores(毛孔). Pores allow liquid, especially sweat,{#blank#}6{#/blank#}(pass) through. By{#blank#}7{#/blank#} (sweat), our bodies keep up a normal temperature. When it is very hot, we sweat a lot, but{#blank#}8{#/blank#}(strange) enough, when it is quite cool, we also sweat. On a cool day, our bodies produce {#blank#}9{#/blank#}average of 700 ml of sweat. That is{#blank#}10{#/blank#}(much) than 0.5 kilos.

My wife and I like watching plays, so we will go to the theater whenever we have time. But before we buy tickets, we would like to know if the play is good or bad. When a new play comes, we {#blank#}1{#/blank#}  (usual) read the newspaper to get information about it. Last week a new play was put on at the theater. The newspaper said it was very {#blank#}2{#/blank#} (interest) so we decided to go on Saturday night. My wife took a long time to make her {#blank#}3{#/blank#} (decide) about what to wear and we left our house a little late. {#blank#}4{#/blank#} the time we got to the theater, the first act had already {#blank#}5{#/blank#} (begin). After the play was over, we met some friends, {#blank#}6{#/blank#} lived next to us several years ago. Then we went dancing. By the time we got home, it was about two o'clock in the morning. I'm not used to {#blank#}7{#/blank#} (stay) out so late and I was {#blank#}8{#/blank#} (extreme) tired.

When I was younger, I did not have the money to go out for {#blank#}9{#/blank#} evening like this. Though I can afford it now, I don't have the energy{#blank#}10{#/blank#}(enjoy) it.
