Big climate changes in the last million years might have come from something very small: dust from outer space.
Earth changes between ice ages and warm periods in a(n) ____ that includes several cycles, including a ___ one that lasts 100,000 years. Scientists ____suggested this cycle might be due to changes in the inflow of cosmic(宇宙) dust.
The idea is that Earth ___above and below the imaginary plane that runs through the sun and Jupiter(木星), completing a cycle every 100,000 years. So maybe it encounters ___varying amounts of dust during each cycle that produce the climate trend.
Now there is some ____, from ancient cosmic dust recovered in ocean-floor drilling near the Azores islands west of Portugal. The large quantity of the dust rises and falls with a wonderful 100,000 year cycle during the period analyzed, 253,000 years to 458,000 years ago. Periods of more dust are related to____ climates.
But that is a long way from showing that the dust ____ climate. Some scientists argue that it is not clear how cosmic dust would make the climate warmer while dust from volcanoes is known to make it cooler. They say the cosmic dust is so thin that it is hard to see how it could have any climate____.
Nevertheless, the new study shows scientists have to take the cosmic dust idea seriously.
A beautiful woman took a plane on business. She found her seat and sat down next to a young man. The man was just thinking of making a few dollars on the plane. When he saw the woman, he got an idea.
“Hey! Would you like to play a game?” he asked the woman. “No, thank you. I just want to take a nap (打盹),” the woman answered. “It’s really easy. All you have to do is to answer the questions that I ask you. If you don’t know the answer, you give me five dollars. If I don’t know the answer to your question, then I’ll give you five dollars.” “No,” the woman still refused. “OK. If I don’t know the answer to your question, I’ll give you five hundred dollars. How about that?” the man said. Then the woman became interested and decided to join in the game.
“OK. How many moons does Jupiter (木星) have?” asked the young man. The woman reached into her purse and took out a five-dollar bill. “What goes up the mountain with three legs and comes back with four?” the woman asked. Then the young man took out his computer and searched the Internet for an answer. Minutes later, the young man handed five hundred dollars to the woman.
After a few hours, the young man really wanted to know the answer to 
the question. So he asked the woman, “What is the answer to your question?” The woman reached into her purse and handed the young man a five-dollar bill.

| A．How do we get the names for the days? B．The origin of division of the times. C．How did men invent the week? D．The Jews names the seven days. E．How did the Egyptians and the Romans name the days? F．Reason for no names of the days. |
Do you know how the days of the week get their names? There was a time in the early history of man when the days had no names! The reason was quite simple：men had not invented the week.
2. _____________
In those days, the only division of times was the month, and there were too many days in the month for each of them to have a separate name. But when men began to build cities, they wanted to have a special day on which to trade, a market day. Sometimes these market days were fixed at every tenth day, sometimes every seventh or every fifth day. The Babylonians decided that it should be every seventh day. On this day they didn't work, but met for trade and religious festivals.
3. _____________
The Jews followed their example, but kept every seventh day for religious purposes. In this way the week came into existence. It was the space between market days. The Jews gave each of the seven days a name, but it was really a number after the Sabbath day(which was Saturday). For example, Wednesday was called the fourth day (four days after Saturday)．
4. _____________
When the Egyptians adopted the sevenday week, they named the days after five planets, the sun, and the moon. The Romans used the Egyptian names of their days of the week: the day of the sun, of the moon, of the planet Mars(火星), of Mercury(水星), of Jupiter(木星), of Venus(金星), and of Saturn(土星)．
5. _____________
We get our names for the days not from the Romans but from the AngloSaxons, who called most of the days after their own gods, which were roughly the same as the gods of the Romans. The day of the sun became Sunnandaeg, or Sunday. The day of the moon was called Monandaeg, or Monday. The day of the Mars became the day of Tiw, who was their god of war. This became Tiwesday, or Tuesday. Instead of Mercury's name, that of the god Woden was given to Wednesday. The Roman day of Jupiter, the thunderer, became the day of the thunder god Thor, and this became Thursday. The next day was named for Frigg, the wife of their god Odin, and so we have Friday. The day of Saturn became Saeterndaeg, a translation from the Roman, the Saturday.
