5月28日用英语怎么说

解题思路：科学记数法的表示形式为a×10ⁿ的形式．其中1≤|a|＜10，n为整数，确定n的值时，要看把原数变成a时，小数点移动了多少位，n的绝对值与小数点移动的位数相同．当原数绝对值大于10时，n是正数；当原数的绝对值小于1时，n是负数．

6 012=6.012×10³．故选B．

点评：
本题考点： 科学记数法—表示较大的数．

考点点评： 此题考查用科学记数法表示大数．用科学记数法表示数的关键是确定a与10的指数n，确定a时，要注意范围，n等于原数的整数位数减1．

哎,为什么不自己写呢?帮你一次吧,希望你看后有收获,祝你进步!
May 28th, Saturday
We went to Renmin Park today. We were required to get together at the gate of our school at 8:00 am. After that, led by our head teacher, my classmates and i left for the park by bike. After about half an hour, we arrived there. We played games in the morning and had a barbecue at noon. In the afternoon, we took many photos and visited the zoo as well. All of us had a very good time and we returned to our school at 5:00 p.m.

同休息

Little Tommy was once an unbelievably clever boy.Even at 3 he could read the (anthology) of Tagore and recite those poems in it,making the whole family (bewildered) but exicted.Naturally he was spoiled and given the greatest care and therefore increasingly (complacent),which in the end led to the family (calamity):he,along with a band of wild children companion,bombed the city (dynamo) in an adventure.Luckily,the accident only (disfigured) his thumb.But the crunch was he was therefore sent to the trail.Although his family was (abashed) by that,they tried their best to save him.They stumbled to make (cumbersome) (contest) that he was not the major plotter,that he was still yound.But the (affidavit) from his companion belied all of their impotent protest and the judge pronounced that he be sent into prison to (expiate).
The incident greatly attenuated the family reputation so finally,after the failure to save him from being sent into prison,they decided to leave him alone.
After the trail he was thrown to his cell.In it he found a (dent) in one corner and decided to do something just for fun.He asked the jailor for some sheets of paper and a pen,for which he paid him all the money he had.Then he wrote the poems he learned during his infant years on one piece of paper and tucked the paper inside the corner.Dramatically,he received a reply letter the next day!On it was a girl's handwriting expressing how incredible it was to see a piece of paper with amorous poems poking outside the corner of the room when she passed by and that he was the most romantic prisoner she had ever seen.He did the same thing the next day and recieved another reply.
After one year in jail,they became the most intimate pen-friends there had ever been.Enclosed with the last letter was a straw ring he made and in the letter he pledge to her that he was a man worthy of being (entrusted) to .After he put the letter slowly into the corner for the last time,he began to dream of the (chromatic) life he was going to lead.

解题思路：“爸爸每工作4天休息一天”，说明爸爸5天中有一个休息日；“妈妈每工作6天休息一天”，说明妈妈7天中有一个休息日；从今天同时休息到下一次他们同时休息经过的时间，既是5的倍数也是7的倍数，要求到几月几日他们又一次一起休息，先求出他们至少再过多少天他们又一次一起休息，根据题意，也就是求5和7的最小公倍数，问题即可得解．

因为1+4=5和1+6=7是互质数，
所以5和7的最小公倍数是：5×7=35，
5月28日那天爸爸、妈妈一起休息，再经过35天是7月2日；
答：到7月2日他们又一次一起休息．

点评：
本题考点： 公因数和公倍数应用题．

考点点评： 此题属于用最小公倍数来解决的实际问题，关键是明确要求的问题就是求5和7的最小公倍数，再根据两个数是互质数，最小公倍数是它们的乘积得解．

1966年6月2日,美国无人驾驶飞船“观察者”号在月球成功登陆,同时向地球发回大量月球表面照片.

鲁道夫·闵可夫斯基（Rudolph Minkowski,1895年5月28日生 ）,美籍德裔天文学家,着名数学家赫尔曼·闵可夫斯基的侄子.
闵可夫斯基仔细研究了气体星云,发展了使用物端棱镜检测行星状星云的方法.他和美国天文学家沃尔特·巴德一起研究了超新星,根据光谱特征将它们分为I型超新星和II型超新星两大类.闵可夫斯基还仔细观测了金牛座的蟹状星云,证实了蟹状星云是1054年爆发的一颗超新星的遗迹.1940年代,他和巴德一起证认了一系列射电源的光学对应体,包括仙后座A（超新星遗迹）、天鹅座A（巨椭圆星系）、半人马座A（近距离椭圆星系）.
闵可夫斯基自1935年起曾先后在威尔逊山天文台和帕洛玛天文台工作,主持了帕洛玛天图计划.整个计划在1948年到1958年间,完成了一套包括1872幅蓝红双色照片在内的北天深空照相星图.1959年闵可夫斯基当选美国科学院院士.1961年,闵可夫斯基开始主持加利福尼亚大学伯克利分校射电天文实验室,直到1976年逝世.

解题思路：应先把35.6万整理为用个表示的数，科学记数法的一般形式为：a×10ⁿ，在本题中a为3.56，10的指数为整数数位减1．

35.6万=356 000=3.56×10⁵．故选C．

点评：
本题考点： 科学记数法—表示较大的数．

考点点评： 将一个绝对值较大的数写成科学记数法a×10n的形式时，其中1≤|a|＜10，n为比整数位数少1的数．
