  In the evening, most people want some kind of entertainment(娱乐). Older teenagers go to the cinema or they go dancing at a club. At home, the television has many p{#blank#}5{#/blank#}for family entertainment, such as The X Factor Merlin or Doctor Who.

 On Sunday mornings, people often have alie-in (懒觉).  That means that they get up l {#blank#}6{#/blank#} than they do during the week. Some people go to church on Sunday mornings. Families often have a big Sunday lunch together. The meal is usually roast meat (beef, chicken, etc. ) with v{#blank#}7{#/blank#}  . And there's usually a big pudding, too.

 After that, a lot of adults spend the afternoon having a nap ( =sleeping) in front of the TV!

    Copernicus was an astronomer(天文学家). He studied the {#blank#}1{#/blank#}(planets/weather) and the stars. He found out that the earth {#blank#}2{#/blank#} (walks/goes) around the sun. He put his thought into a book, but he hid the book. Nobody could read it {#blank#}3{#/blank#} (before/after) Copernicus died.

    Many years later, Galileo {#blank#}4{#/blank#} (read/watched) the book and believed that thought. Galileo said that the earth was moving around the sun. This made lots of people {#blank#}5{#/blank#} (happy/angry) because they thought the earth must be the center of the universe. Galileo got into trouble and he had to say that he was {#blank#}6{#/blank#}(brave/wrong), but Galileo knew he was right.

    Galileo watched the moon carefully through his telescope(望远镜). He {#blank#}7{#/blank#}(invented/saw) some hills there. He also saw {#blank#}8{#/blank#} (millions/millions of) stars in the universe. In 1673 his eyes became weak, and then he couldn't see {#blank#}9{#/blank#}(anything/nothing) through his telescope.

   Galileo died in 1642 and the world lost a {#blank#}10{#/blank#} (funny/great) man. But in the same year, another great scientist Newton was born in England.

    Different countries have different rules about social situations, so when you meet foreign friends, you are {#blank#}1{#/blank#} to learn about the culture in other countries. For example, if you have an appointment(预约) {#blank#}2{#/blank#} four o'clock, what time do you {#blank#}3{#/blank#} your foreign friends to come? If they are Germans, they will {#blank#}4{#/blank#} on time. If they are Americans, they'll probably be fifteen minutes {#blank#}5{#/blank#}, but if they are Englishmen, they'll be fifteen minutes late, because sometimes they are {#blank#}6{#/blank#} about time.

    As for lunch time, the Englishmen are happy to have lunch with {#blank#}7{#/blank#} business friends. During the meal, they often discuss business matters. The Japanese don't like to work while eating, {#blank#}8{#/blank#} lunch is the time for them to relax. The Germans like to talk about business before dinner, but the Frenchmen {#blank#}9{#/blank#} eat first and talk after dinner. So if we learn many {#blank#}10{#/blank#} of other countries, we can have a great time with foreign friends.
