Since long ago,greeting cards have been considered a time-saver.More than 150 years ago,a busy Englishman,Sir Henry,asked a friend to design a card so that he didn't have to labour to write holiday letters to his friends at the end of the year.Those paper cards are now the tradition.

But time,like sunlight,is still in short supply for December.That's why the Internet is ready to make a change in holiday greeting customs.Already,those,who are always busy,like sending video greetings by e-mail.So,don't be surprised to find a lively card in your electronic mail box at the end of the year or at any time you should have one.

A recent survey by the Shared Greetings Company found 50 percent of all the Internet users will send online cards especially during the holiday seasons.“That is a lot easier,and it is lively,”said Carol,a New Yorker,who had stopped at the Shared Greetings Company demonstration() online.With her children's help,she sent her first e-card before Thanksgiving Day.“It was the first time I had done something like this;it's quite enjoyable,”she said.

“I will send online Christmas cards to my friends,”said Marcos,a 22-year-old student.“It costs so little and you can even send numbers of greetings at a time.”But he added “the e-card also has its limits,and I don't think it is ready to replace the paper card for the more formal or traditional occasions.For some people,I would rather buy paper cards and mail them traditionally.I believe it is more personal and respectful in that way,”he said.

Well,for those who are very busy but still prefer to do a lot of greetings to different receivers in the holiday season,the Internet may have another way.“Now you can use the Net to decide and send as many as 50 beautiful cards,which allows the buyer to choose the inside saying,as well as the ink colour and typeface,only costing about 30 minutes,”said Julie,vice-president of marketing for an electronic card company-Hallmark Company.“And if you are in less of a hurry,you can spend another 30 minutes sitting in your home or office to create a photo card,showing off your kids,your pets or even your new house-anything as your favorite design for your relatives and friends.”

How can we understand “But time,like sunlight,is still in short supply for December”in Paragraph 2?

A.December cannot supply enough time for people because the sunlight in this month is short.

B.People are always busy at the end of the year,so time is precious like the sunlight in winter.

C.Time is short at the end of the year,like the sunlight in December.

D.Time passes quickly like the sunlight in winter as December comes.

According to the 22-year-old student,he would probably mail e-cards to everyone except_________.

A.the members of his family

B.his girlfriend

C.the teachers who have taught him

D.his schoolmates

If you are quite busy,but having many greetings to send,which of the following is your best choice?

A.Ordering a lot of cards you like online and sending them from the post office.

B.Getting as many cards from your electronic mail box and mailing them on the Net.

C.Sitting and writing lots of beautiful cards at home and sending them just in a traditional way.

D.Choosing personalized cards in numbers and mailing them directly on the Net.

There are no exact differences between physics and other natural sciences because all sciences overlap(重叠).In general,however,physics is the scientific study of forces and qualities such as heat,light,sound,pressure,gravity and electricity,and the ways they affect other objects.

One major branch of physics deals with the states of matter—solids,liquids and gases and with their motions.The pioneer achievements of Galileo,Kepler and Newton dealt with solid masses of matter in motion.Such studies deal with forces acting on moving objects.It is the subject of mechanics and belongs to the branch of mechanics called dynamics,the study of matter in motion.This large topic includes not only the motions of stars and ping-pong balls but also the motions of the water pumped by a fire engine and those of the air passing through the jet engine of an airplane.

A branch of mechanics is statics(静力学),the study of matter at rest.The designs of buildings and bridges are examples of problems in statics.Other branches of physics are based on the different kinds of energy,which interact with matter.They deal with electricity and magnetism(磁力),heat,light,and sound.From these branches of physics scientists find clues(线索) which have revealed(揭示) the constructions of atoms and how the atoms react to various kinds of energy. This knowledge is often called the basis of modern physics.Among the many subdivisions(细的分支) of modern physics are electronics and nuclear physics.Physics is closely related to engineering.A person who uses knowledge of physics in solving everyday problems is often called an engineer.For example,electricity is one of the branches of physics;and an electrical engineer is a man who uses the “natural laws” of electricity to help in designing and electric generator(电动机).

Physics is not exactly different from other natural sciences because_________.

A.physics and other natural sciences have parts in common

B.it is the scientific study of forces and qualities such as heat,light and sound

C.it studies the ways in which forces and qualities affect other objects

D.it is a part of other natural sciences

The following statements are included in the study of dynamics except_________.

A.the design and construction of skyscrapers

B.the motions of heavenly bodies

C.the motions of water pumped by a fire engine

D.the motions of the air passing through the jet engine of an airplane

Among many branches of modern physics is _________.

A.states                        B.electricity                  C.electronics                 D.mechanics

This knowledge” in Paragraph Three refers to_________.

A.electricity and magnetism,light and sound

B.the construction of atoms and their reactions to various kinds of energy

C.the basis of modern physics

D.electronics and nuclear physics

Snow-melting Agent

A heavy snow can kill pests and this means a good harvest next year.This will bring as well as trouble to urbanites.

On Nov.16,2003,a cold air current brought a heavy snow to Beijing.To prevent traffic jams,related government departments mobilized people to clear off snow on streets.

One of the most effective ways to clear off snow on roads is to scatter snow-melting agent on the roads.The major component of the snow-melting agent is salt.The snow-melting agent can make snow stop from freezing,make it easier to clear off the road,and allow traffic to flow smoothly.But it also brings about some hidden dangers.In the spring of 2003,over 300 000 trees in Beijing urban districts died.After analyzing soil around these trees,experts discovered that the salt content of these soils was 392 times higher than normal.Where did the excessive salt come from?After investigating,forestry experts found that when clearing snow in the winter,people usually heap snow containing snow-melting agent at trees’ roots,and that when the snow melts,this agent penetrates the soil and increases its salt content.The snow-melting agent indirectly killed the trees.

Statistics show that during a heavy snow in 2002,over 1000 tons of snow-melting agent was scatterred on streets in Beijing.Snow water containing a large amount of snow-melting agent got into the soil through sewers.

In addition,salt in the snow-melting agent can expedite the corrosion of steel bars in concrete buildings and cause the concrete to crack and peel,shortening the life of roads.

Scientists and government officials are required to solve traffic problems caused by heavy snows as soon as possible and at the same time try to reduce the negative effects of the snow-melting agent.This is a difficult problem placed before them.Related authorities have framed some local criteria to regulate the production and use of snow-melting agents.

Now,more harmless snow-melting agents are being developed.Now that even snow-melting agents that meet today’s criteria must still be used carefully,we have to rely more on our manpower and machines to clear off snow.

This year,in addition to using snow-melting agents,Beijing will use a large number of snow vehicles to clear snow on roads.In more places,citizens are mobilized to clear snow with their hands.This may be a test of a city’s civilization level.

Salt is a snow-melting agent while _________ is a cleaning agent.

A.water                 B.soap     C.a washing-machine     D.a housewife

The third paragraph of the text is mainly about _______.

A.the side effect of snow-melting agent

B.a case of damage to trees caused by snow-melting agent

C.the results of using snow-melting agent

D.the uses of snow-melting agent

According to the text,the most practical way to clear off snow is to _________.

A.use snow-melting agent as much as possible

B.only use more harmless snow-melting agent

C.encourage people to clear snow with their hands

D.use more snow vehicles

This text most probably appears in_________.

A.a newspaper                                                        B.a magazine on latest findings

C.a book on salt                                               D.a magazine on environmental protection
