Extra Information—周一到周日的由来
这些名称最早起源于古巴比伦（Babylon）。公元前7-6世纪，巴比伦人便有了星期制。他们把1个月分为4周，每周有7天，即1个星期。古巴比伦人建造七星坛祭祀星神。七星坛分7层，每层有1个星神，从上到下依次为日、月、火、水、木、金、土7个神。
7神每周各主管1天，因此每天祭祀1个神，每天都以1个神来命名：太阳神主管星期日，称日曜日；月神主管星期一，称月曜日；火星神主管星期二，称火曜日；水星主管星期三，称水曜日；木星主管星期四，称木曜日；金星神主管星期五，称金曜日；土星神主管星期六，称土曜日。所以在一些国家的语言中，一星期中的各天并不是按数字顺序，而是有着特定的名字，是以“七曜”来分别命名的。
古巴比伦人创立的星期制，首先传到古希腊、古罗马等地。古罗马人用他们自己信仰的神的名字来命名1周7天：Sun’ s-day（太阳神日）、Moon’ s-day（月亮神日）、Mars’ s-day （火星神日）、Mercury's-day（水星神日）、Jupiter’s-day（木星神日）、Venus’ -day（金星神日）、Saturn’s-day（土星神日）。这7个名称传到不列颠后，盎格鲁-撒克逊人又用他们自己信仰的神的名字改造了其中4个名称，以Tuesday、Wednesday、Thursday、Friday分别取代Mar's-day、Mercury's-day、Jupiter's-day、Venus'-day。公元三世纪以后，就广泛地传播到欧洲各国。明朝末年，基督教传入我国的时候，星期制也随之传入。
在不同地区，由于宗教信仰的不同，一星期的开始时间并不完全一致。埃及人的一星期是从土曜日开始的，犹太教以日曜日开始，而伊斯兰教则把金曜日排在首位。在我国，起初也是以七曜命名一星期中的各天，到清末才逐渐为星期日、星期一……星期六所代替，习惯上认为星期一是开始时间（某些地区也有把星期日作为一周开始的观念）。
星期的演化
1.周日（日曜日）：Sunday（Sun.）—Day of the Sun(太阳日，星期日)。是耶酥复活日，因此西方把这一天看作最神圣的日子，称之为“安息日”或“主日”。公元4世纪，在指定罗马历法时，罗马皇帝君士坦丁大帝把这一天定为合法假日，后被世界各国广泛采用。
2.周一（月耀日）：Monday(Mon.)—Day of the Moon(月亮日)。在古英语中写作Monandoeg, 即 day of the moon。在古罗马神话中，月亮神为太阳神之妻，因此一周中，也应有她一天。
3.周二（火曜日）：Tuesday(Tues.)—Day of the Mars(火星日)。这一天是为了纪念战神Tyr而由他的名字命名的。古英语中Tyr的名字写作Tiw。周二在古英语里写作Tiwesdoeg的意思是Tiw’ s day（战神日）。Tyr原是北欧神话里的战神，他用自己的手作诱饵，捉住了狼精，他的手却被狼精咬掉了。为了纪念他这种勇敢的精神，使用他的名字来命名Tuesday这一天。
4. 周三（水曜日）：Wednesday(Wed.)—Day of the Mercury(水星日)。这一天是以北欧神话中掌管文化、艺术、战争、死亡的神Woden的名字命名的。Woden是战神Thor的父亲；他勇敢地将在宇宙间制造混乱的“混沌”（Chaos）杀死，并将阵亡将士的英灵请到天界，使他们享受天伦之乐。为怀念他，人们用他的名字命名了Wednesday这一天。
5. 周四（木曜日）：Thursday(Thur.)—Day of Jupiter(木星日)。这一天是用北欧神话中Thor的名字来命名的。Thor是掌管雷电之神（God of Thunder and Lightning）。他常驾驭着由山羊拉的战车奔驰在天际间，风儿飕飕成了闪电，车轮滚滚成了雷鸣。
6.周五（金曜日）：Friday(Fri.)—Day of Venus(金星日)。Friday在古英语中写作Frigedoeg。Frigga是掌管婚姻的女神。她是Woden之妻，Thor之母。因为以Woden之名命名了Wednesday,以Thor之名命名了Thursday，为了抚慰她本人，便以她的名Frigga命名了Friday。
7. 周六（土曜日）：Saturday(Sat.)—Day of Saturn(土星日)。这是一星期中最后一天，它是由掌管农业之神，罗马主神朱庇特的父亲（the god of Agriculture, father of Jupiter）Saturn的名字命名的，也是英语直接用罗马神话中神名来命名星期名称的唯一的一天，其余几天则是以北欧神话中的神名来命名的。
与星期有关的英语词语：
in one's Sunday best穿着节日盛装
Black Monday（放假后的）开学第一天
blue Monday烦闷的星期一；沮丧的时候
Mad Monday（交易所）忙乱的星期一（因为这一天交易所特别忙
Good Friday耶稣受难日（复活节前的星期五）

Reading and Writing
I. Reading Comprehension
A. Choose the best answer
In the United States, millions of women work outside their homes. Some of these women must work to support their families. However, many have children too young to go to school. Who looks after these children all day while the mothers work?
In the past, grandmothers or other relatives often lived with the family. The older relatives stayed at home and took care of the children. But young parents began to move into their own small houses or apartments, and there was no room for relatives. Some mothers could hire baby-sitters to look after their children, but many could not pay for it.
Today, our cities are filled with more than 500,000young children who are alone all day. These children are called “Latchkey kids”, for around their necks hang the keys that open their empty rooms. Nobody waits for them inside.
Mothers need a place to leave their children while they work, and children need better care. They need someon
