1_____ 
     Science is an amazing subject, but it's difficult to capture the true magic of science and contain it in a book.
For young learners, textbook science often looks like a lot of big, confusing terms that have to be memorized.
That is why sometimes children think that science is dry, boring and difficult. Textbooks can't help them
discover how exciting science really is. So find some other ways to help kids to develop a love of science. 
2_____
     Instead of just reading from a book about the water cycle, air pressure, chemical changes, sound waves,
fingerprints, etc., let students experience these things instead. It's much more memorable for them to discover
a principle or fact about science on their own than it is to simply be told about it. There are great resources
online that include complete lesson plans for hundreds of activities. Afterwards, a brief discussion can bring
the principal points home to children. In addition, an explanation of any unfamiliar terms at this point will make
a lot more sense. 
3_____ 
     Science is all around. Taking time to look at the world and to discuss what is seen, encourages scientific
observation and a love of learning. Look at changing seasons, weather events, plants, pets, insects, the stars
and virtually everything else as an opportunity to help students learn more about science. 
4_____
     Real scientists record their findings. Encourage young scientists to draw pictures and write about what they
see and do. Science isn't an isolated subject. It involves reasoning, writing, math, history, art, and more. A
journal gives students a place to record the things about science that interest them most. 
5_____
     Cooking is filled with chemical reactions. Teach students about what happens when carbon dioxide bubbles
form in dough. Help them to understand mixtures by making a salad, solvents by mixing up powdered drink
mixes, colloids by making gelatin, evaporation and cloud formation by observing a boiling tea kettle. Crystals can
be observed (and grown) with salt and sugar. Liquids can be changed to solids in a freezer. The list is almost
endless.

科目:高中英语 来源:2013届陕西省师大附中高三第四次模拟考试英语试卷(带解析) 题型:填空题

根据短文内容,从下框A~F选项中选出能概括每段主题的最佳选项,并在答题卡上将该选项涂黑。选项中有一项为多余项。

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.
1._____________
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.
