(9)当地球公转到C点时,福州正午太阳高度角最小,影子最长;此时,福州的昼夜长短情况是______;

(10)当地球运动到C点时,太阳直射在______线上,此时澳大利亚的学生是将要放______(暑假、寒假).

答案

参考答案:

(1)

(2)极昼;C;

(3)B;昼夜平分;

(4)昼长夜短;

(5)AD;

(6)春分;

(7)B;

(8)②;

(9)昼短夜长;

(10)南回归;暑假.

解析:

分析:地球公转的方向是自西向东,公转的周期是一年,公转产生的地理现象是:①昼夜长短的变化;②四季的形成.

解答:

(1)地球公转的方向是自西向东或是逆时针方向的.

(2)当地球公转至D处时,太阳直射北回归线,日期为6月22日左右,是北半球的夏至日,北极圈及以北地区出现极昼现象,此时南平地区正午太阳高度角最大,影子最短.当地球公转C处时,太阳直射南回归线,为北半球冬至日,此时北半球白昼时间最短,夜最长.

(3)当地球公转至B处时,是北半球的秋分日.这时全球的昼夜长短情况是昼夜等长.

(4)当地球从A转到D时,即由春分日到夏至日间,北半球的白昼时间变长,黑夜时间变短.

(5)根据公转原理可知,A为北半球春分日,时间大约为3月22日前后,B为北半球秋分日,时间约为9月22日前后,C为北半球冬至日,时间约为12月23日前后,D为北半球夏至日,时间约为6月22日前后,故5月1日--6月1日,在此期间地球在公转轨道上的位置处在AD之间.

(6)当地球转至A点时,北半球是春分节气,太阳直射在赤道上.

(7)天宫一号是中国第一个目标飞行器,于2011年9月29日21时16分3秒在酒泉卫星发射中心发射,此日期靠近北半球秋分日,故此时地球在公转轨道的位置比较接近是B处.

(8)我国位于北半球,10月15日正好处在秋分日和冬至日间,即图上BC之间.

(9)当地球公转到C点时,正值北半球冬至日,此时福州正午太阳高度角最小,影子最长,福州的昼夜长短情况是昼最短夜最长.

(10)当地球运动到C点时,太阳直射在南回归线上,此时澳大利亚的学生是将要放暑假.

     For Chinese students the end of their senior year is filled with studying and stress as they prepare for

the college entrance exams in June. But for American high school seniors the experience couldn't be more different. The end of senior year is a celebration of their time in high school and involves parties, games

and fun.

     Senioritis is a commonly used expression. It means seniors have a disease which makes them unable

to do work. This starts in April when seniors find out where they have been accepted to university.

     Unwilling to do school work, seniors have plenty of other activities to focus on. Many schools have

a "Senior Show", in which only seniors are allowed to perform. Some seniors sing or dance but many of

them perform skits (滑稽短剧), where they make fun of their favorite teachers or their friends. For

example, a group of boys may dress up and imitate a group of their girl friends. It is all very light-hearted.

     The "Senior Show" is usually a part of Senior Week, which is a week specifically dedicated (专用的)

to seniors. During this week, seniors usually get academic or athletic awards they have won over their

high school careers. The seniors also vote for one of their male and female classmates who they believe is

the best-looking or funniest or most involved, etc. These are then published in the yearbook.

     The yearbook is an important part of high school for seniors. It is usually dedicated to them and has all

their pictures and a quote from them in it. Then seniors go around and get it signed by their friends so they can always remember their time together.

     Of course during all of this time, seniors are preparing for the Senior Prom, which is an important

moment in American culture. It is the most important dance in a young American's life.

    The end of senior year is a truly special and wonderful time for American students. It's something they

will remember for the rest of their lives.
