Like human beings, dogs may catch cold because of cold weather, wet conditions or can also get it from other sick dogs. If a dog has a running nose and watery eyes, coughs or sneezes(打喷嚏）, then it is quite probable that the dog has caught cold.
A dog's cold can get over after a few days without treatment but it totally depends upon the owner to treat it with medications or improve its immune power（免疫力）to get rid of the cold naturally. Following are some of the things you can do if your dog gets a cold.
You can improve its immune power by giving it proper nutrient diet. Healthy food can really do wonders. Try to give it food which is either suggested by the vet（兽医）or is healthy for your pet. Increase the intake of food which is rich in vitamins A, C and E.
Keep your dog warm. The best place for your dog in winter is inside your house. Do not keep your dog outside when it is cold and wet. At home you can also keep the dog warm with the help of carpets. This will make him comfortable and help him to recover fast.
Increase the fluid（流质）intake as it helps a lot. Water can be the best choice but you can also add broth（肉汤）in water which will give your dog strength. Warm water will make your dog more comfortable and will also keep the dog away from the respiratory infections（呼吸道感染）.
Steam treatment is considered to be effective in getting rid of cold. It makes the nasal（鼻的）passage wet, which helps proper breathing. Just fill your bathroom with steam and leave your dog inside the bathroom for 15 minutes. Do it nearly 2 to 3 times a day and you will see your dog recovering.
These are some of the things you can do to help your dog recover from cold. However, if you are not able to find any improvement in its health, then turn to the vet for help immediately. Take your dog for regular checkups so as to avoid complications（并发症）.From the first paragraph we know about __________.

That little “a” with a circle curling around it that is found in E – mail addresses is most commonly referred to as the “at” symbol.
Surprisingly though, there is no official, universal name for this sign. There are dozens of strange terms to describe the "@" symbol.
Before it became the standard symbol for electronic mail, the "@" symbol was used to represent the cost of something or how heavy something is. For instance, if you purchased 6 apples, you might write it as 6 apples "@" $1.10 each.
With the introduction of e-mail came the popularity of the "@" symbol. The "@" symbol or the "at sign" separates a person's online user name from his mail server(服务器) address. For instance, joe@uselessknowledge.com. Its widespread use on the Internet made it necessary to put this symbol on keyboards in other countries that have never seen or used the symbol before. As a result, there is really no official name for this symbol.
The actual origin of the symbol remains a mystery. History tells us that the @ symbol came from the tired hands of the Middle Ages. During the Middle Ages before the invention of printing machines, every letter of a word had to be copied with great efforts by hand for each copy of a published book. The monks that performed these long, boring copying duties looked for ways to reduce the number of individual strokes (笔画) per word for common words. Although the word “at” is quite short to begin with, it was a common enough word in text and documents so that those monks thought it would be quicker and easier to shorten the word “at” even more. As a result, the monks changed the shape of “t” into a circle to surround “a”, thus leaving out two strokes in the spelling “t”.
45．Which of the following is the best title of the passage?
A．How “at” developed into @. B．How @ came into being.
C．How monks invented @. D．How people wrote the cost of something.
46．Who knows the origin of @?
A．Nobody B．Monks C．Apple buyers D．Internet users
47．Which is NOT the reason for the monks to spell “at” as @?
A．Though “at” is short, it was used very often.
B．The monks wanted to be quicker and easier with their copying.
C．The monks wanted to invent a new word.
D．Copying work was long and boring for them.
48．According to the paragraph , which is TRUE about the symbol of @ today?
A．When you are online, you must use the @ symbol.
B．Kittly 163.com@is an email address.
C．In countries where @ is used, governments have given it an official name.
D．It is likely to find the @ symbol on computer keyboards worldwide.
Wind is the great maker of waves. There are exceptions, such as the tidal waves, sometimes produces by earthquakes under the sea. But the waves most of us know are produced by winds blowing over the sea.Now before constructing an imaginary life history of a typical wave, we need to know certain physical things about it. A wave has height, from trough (low point)to crest (high point),and it has length—the distance from this crest to that of the following wave. The period of the wave means the time it takes for succeeding crests to pass a fixed point. None of these things stays the same— for all depend upon the depth of the water and many other matters.
The water that makes up a wave does not advance with it across the sea. Each drop of water turns around in a little circle with the passing of the wave, but returns very nearly to its original position. And it is fortunate that this is so, for if the huge masses of water that make up a wave actually moved across the sea, sailing would be impossible.
If we want to find the speed of a wave, we may use the following way:
Speeding="Wavelength×Frequency"
Here, wavelength is the distance between two high points (crests), frequency means the number of cycles per second.
41.What causes waves according to the passage?
Earthquakes and nothing else. B. Wind and volcanos.
C. Wind and earthquakes. D. Wind and water.
42.Which of the following is true according to the text?
A. The water of a wave moves away across the sea.
B. The water of a wave remains almost in the same place.
C. The water of a wave goes with the passing of the wave.
D. The length of a wave means the distance between crest and trough.
43.The underlined word “succeeding” means__________.
A. reaching an aim B. doing well C. following after D. taking place
44.If the speed of wave 1 is 100 cm/s, and its frequency 10;and the frequency of wave 2 is 300,while its speed is twice that of wave 1.Which of the following is true?
A. The wave-lengths of the two are equal.
B. The wave-length of wave 1 is 10 times longer than that of Wave 2.
C. The wave-length of wave 2 is longer than that of wave 1.
D. The wave-length of wave 1 is longer than that of wave 2.

More and more often we heard of people talking about Karaoke（卡拉OK）。 But what on earth it is about， still remains a question for many people. Karaoke is a sort of acoustic equipment which was invented in Japan around the middle of the 1970's. It means "a band without people" in Japanese. In fact， it is just a music tape without words. This equipment first appeared in some public houses and snack bars， and mainly for the customers to enjoy themselves. Most of the music in Karaoke was popular music. Therefore， at times， when anyone felt like it， he might sing songs to the accompaniment of the music that came from the equipment. Shortly after its invention， Karaoke was spread to the whole world. It was introduced to China and was welcomed by many people. Although you are not a good singer， or even sometimes you may sing out of tune， you can always enjoy yourself by singing Karaoke.
