The word “day” has two meanings. When we talk about the number of days in a year, we are using “day” to mean 24 hours. But when we talk about day and night, we are using “day” to mean the time between sunrise and sunset. Since the earth looks like a ball, the sun can shine on only half of it at a time. Always one half of the earth is having day and the other half night. A place is moved from day into night and from night into day over and over by the spinning（旋转）of the earth. At the equator（赤道）day and night are sometimes the same length（长度）. They are each twelve hours long. The sun rises at 6 o’clock in the morning and sets at 6 o’clock in the evening. For six months the North Pole is tilted（倾斜）toward the sun. In those months the Northern Hemisphere（半球）gets more hours of sunlight than the Southern Hemisphere. Days are longer than nights. South of the equator nights are longer than days. For the other six months the North Pole is tilted away from the sun. Then the Southern Hemisphere gets more sunlight. Days are longer than nights. North of the equator nights are longer than days. Winter is the season of long nights. Summer is the season of long days.
（  ）6.When the Western Hemisphere is having day, the Eastern Hemisphere is having ________.
　　     A. both day and night              B. day
　　     C. neither day nor night            D. night
（  ）7. A place is moved from day into night and from night into day over and over by ________ of the earth.
　　     A. the pushing                    B. the pulling
C. the spinning                    D. the passing
（  ）8. At the equator day is as long as night ________.
　　        A. sometimes     B. never       C. usually        D. always
（  ）9. When the North Pole is tilted toward the sun, the Northern Hemisphere gets ________ sunlight.
　　    A. less           B. more       C. all            D. no
（  ）10. When it is winter in China,  ________.
　　    A. the USA is tilted toward the sun
　　    B. the South Pole is tilted away from the sun
　　    C. the North Pole is tilted toward the sun
　　    D. the North Pole is tilted away from the sun

　　Dear Roni,

　　Italy is wonderful. We started in Rome two weeks ago, drove to Florence last week and now we're on our way to Venice. Three weeks just isn't enough.

　　The country near Florence is so beautiful－hills, olive trees. And red roofs(屋顶) of the houses look so nice far away.

　　I am afraid I am getting bigger－the food here is so delicious!

Love,

Akemi

　　Hi Roni,

　　I can't believe(相信) you went to school here in Honolulu! Why did you leave?

　　I spend each morning on the beach(海滩) and in the water. The sand is so soft and the beaches seem so long. The water is just the right temperature.

　　One afternoon, I left the beach to walk in mountains near Honolulu. I enjoyed myself very much there.

　　How I miss you!

　　Dear Roni,

　　Maybe I'm strange but I love the desert(沙漠)!

　　Last week, our group spent four days in the desert. At times, it felt like the moon.

　　I always thought deserts were all the same! They are not. Some parts look like mountains; others are really different.

　　And when we find something green－－a few plam trees, a little water, we feel good and great.

　　See you in September,

Kim
