早上和黑夜

《白天和黑夜》 1、一天中太阳位置的变化规律是（自东向西）。太阳高度的变化规律是（低-高-低）。 2、一天中，阳光下物体影子的变化规律是（自西向东），影子长短的变化规律是（长-短-长）。 3、影子的方向和太阳的方向（相反）。 4、一天中气温变化的规律是（低=高-低）。 5、（日晷）也叫太阳钟，是测量时间的工具，是根据太阳和影子的关系制成的。 6、日晷有（赤道日晷）和（地平日晷）两种。 7、使用手掌日晷是要注意：面向（正南方），（掌心）向上，平端（横放）在胸前，上午用（左手），下午用（右手）。 8、（地球自转）是产生昼夜交替现象的原因。 9、地球自转的方向是（自西向东），地球自转一周的时间大约是（24小时）。 10、古希腊天文学家（托勒密）提出（地心说），他认为（地球）是宇宙的中心，日月星辰都是围绕地球旋转，这样就形成了白天和黑夜。 11、16世纪（波兰）天文学家（哥白尼）提出了（“日心说”）——不是太阳在运动，而是地球绕着太阳在旋转，这样就形成了白天和黑夜。 12、2008年北京奥运会的开幕式定在晚上8点，那么，美国应该在（上午），德国应该在（中午），澳大利亚应该在（晚上）收看实况直播。 13、我们看到的月光是月球反射的（太阳）的光。 14、随着月球围绕（地球）的公转运动，月相变化的顺序是（新月-蛾眉月-上弦月-凸月-满月-凸月-下弦月-蛾眉月）。 15、月球自转的方向是（自西向东），月球自转一周的时间是（农历的一个月）。 16、（昼夜的交替变化

Review Outline of Grade Science (Part I)

Unit 1 Day and Night

1. The changing rule of the sun's position in a day is (from east to west). The variation law of the sun's height is (low-high-low).

2. In a day, the changing rule of the shadow of an object in the sun is (from west to east), and the changing rule of the shadow length is (long-short-long).

3. The direction of the shadow and the direction of the sun (opposite).

4. The law of temperature change in a day is (low = high-low).

5. (Sundial), also known as sun clock, is a tool for measuring time and is made according to the relationship between the sun and the shadow.

6. There are two kinds of sundials (equatorial sundial) and (horizon sundial).

7. When using the palm sundial, you should pay attention to: face (due south), (palm) up, flat end (horizontal) on your chest, use it in the morning (left hand) and afternoon (right hand).

8. (Earth's rotation) is the cause of the alternation of day and night.

9. The direction of the earth's rotation is (from west to east), and the time for the earth to rotate once is about (24 hours).

10. The ancient Greek astronomer (Ptolemy) put forward (geocentric theory). He believed that (the earth) is the center of the universe, and the sun, moon and stars all revolve around the earth, thus forming day and night.

The 16th century (Poland) astronomer (Copernicus) put forward ("Heliocentrism")-it is not the sun that moves, but the earth rotates around the sun, thus forming day and night.

12. The opening ceremony of the 2008 Beijing Olympic Games is scheduled for 8: 00 pm. Then, the United States should watch the live broadcast at (morning), Germany at (noon) and Australia at (evening).

13. The moonlight we see is the light reflected by the moon (the sun).

14. With the revolution movement of the moon around (the earth), the sequence of moon phase changes is (new moon-female eyebrow moon-first quarter moon-convex moon-full moon-convex moon-bottom quarter moon-female eyebrow moon).

15. The direction of the moon's rotation is (from west to east), and the time of the moon's rotation is (one month in the lunar calendar).

16. (The alternation of day and night
