The Diet Zone: A Dangerous Place
Diet Coke, diet Pepsi, diet pills, no-fat diet, vegetable diet… We are surrounded by the word “diet” everywhere we look and listen. We have so easily been attracted by the promise and potential of diet products that we have stopped thinking about what diet products are doing to us. We are paying for products that harm us psychologically and physically（身体上）.
Diet products significantly weaken us psychologically. On one level, we are not allowing our brain to admit that our weight problems lie not in actually losing the weight, but in controlling the consumption of fatty, high-calorie, unhealthy foods. Diet products allow us to jump over the thinking stage and go straight for the scale（秤）instead. All we have to do is to swallow or recognize the word “diet” in food labels.
On another level, diet products have greater psychological effects. Every time we have a zero-calorie drink, we are telling ourselves without our awareness that we don’t have to work to get results. Diet products make people believe that gain comes without pain, and that life can be without resistance and struggle.
The danger of diet products lies not only in the psychological effects they have on us, but also in the physical harm that they cause. Diet foods can indirectly harm our bodies because consuming them instead of healthy foods means we are preventing our bodies from having basic nutrients(营养成分). Diet foods and diet pills contain zero calorie only because the diet industry has created chemicals to produce these wonder products. Diet products may not be nutritional, and the chemical that go into diet products are potentially dangerous.
Now that we are aware of the effects that diet products have on us, it is time to seriously think about buying them. Losing weight lies in the power of minds, not in the power of chemicals. Once we realize this, we will be much better able to resist diet products, and therefore prevent the psychological harm that comes from using them.

Visitors worry that London is an expensive city but there really are so many things to do for
free in London from museums and galleries to free music and walking tours.
Art Galleries
Tate Modern and Tate Britain are exceptional national art galleries housing some of the finest artworks in the world. Tate Modern focuses on contemporary art while Tate Britain displays British Art from the sixteenth century to the present day.
Museums
All of London's major museums are free, but most offer some special exhibitions for a fee. My favorite is the Museum of London where you can learn the history of London from Roman times to today. Other great major museums are the British Museum, the V&A, the Science Museum, and the Natural History Museum. Oh, and I love the Geffrye Museum. And the Horniman Museum. Now I can't decide which is the best!
Many of London's major art galleries and museums are open in the evening and often have special evening events. This can be a great way to relax at the end of a busy day seeing the sights. The main London galleries and museums are air-conditioned so it can be a wonderful way to cool down in the height of summer in the city. Galleries and museums are not open late every night so here is a handy list to help you plan your days and evenings.
Royal Parks
Many people say the Queen
Mary's Rose Gardens in Regent's Park is their favorite spot in London, and who am I to argue? I would also recommend St. James's Park as it offers one of
the best views of Buckingham Palace. Hyde Park is enormous and includes the
ever popular Diana Memorial Fountain and the Peter Pan Statue.
There are often free talks and guided walks in the royal parks so do check the What's On section of the Royal Parks website.
Changing of the Guard
No visit to London is complete without seeing this military tradition. The Queen's Guard in London changes in the Forecourt inside the gates of Buckingham Palace at 11:30am every day
in the summer and every other day in the winter. Get there early and view the
spectacle from outside the front gates.

Christmas bird – watching is popular in the U.S.A. When the holiday season comes, some Americans are likely to watch and count birds in the sky with great interest every day. This activity began in the early part of the last century. It has a one-hundred-year history. At that time, there was a so-called “holiday hunting” custom. In order to celebrate the holiday, the hunters went out to kill birds and beasts. By 1900, there were 27 bird lovers who decided to count birds instead of killing birds. Since then, Christmas bird-watching was held every year. It has been continued to the present.
There were 42000 people who took part in the bird-watching last Christmas, from December 16 the year before to January 3 next year. They were in the United States and Canada, central America, south America and the Caribbean, watching and counting birds in the sky. The whole viewing area was divided into 1600 points. Each birdwatcher was responsible for 25 meters, and was required to write down the types and quantities of birds within 24 hours.
A birdwatcher described what he had watched vividly in his diary—“ When I looked up, I saw a beautiful ‘landscape’ in the sky: Red-crowned cranes(丹顶鹤) were driving up in cunning wedges that split the air. They were so neatly arranged, coordinating their movements. I was excited and breathtaking. Interestingly, the “human” shape(人字行) always maintains 110° ” .
“Why do red-crowned cranes choose to use ‘human’ shape when flying in formation?” He continued, “In my opinion, there are four reasons: first, the ‘human’ shape can make red-crowned cranes use increasing air which is produced by each other’s wings when they are swinging in the sky. It can increase the glide time and save physical ability. Second, the ‘human’ shape will enhance communication among the birds. The orders and the relevant information issued by the lead bird can be conveyed to each member in this migratory group unimpeded, accurately, rapidly and conveniently. Third, such a formation will help to find the birds left behind because of feeling run down as fast as possible, so that the young, the weak, the sick birds can get everyone’s help and encouragement. Finally, the ‘human’ shape shows not only beauty but also unity. It can give enemies a deterrent.They will be terrified and did not dare to attack the birds.The migration security of the birds will be ensured.”
Environmental experts admired and evaluated Christmas bird-watching highly. They pointed out that it made perfect sense. On the one hand it could enhance the human awareness of environmental protection. On the other hand it could provide first-hand information on birds.

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”.
1.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.
2.Who knows the origin of @?
A．Nobody B．Monks C．Apple buyers D．Internet users
3.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.
4.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.
1.What causes waves according to the passage?
A. Earthquakes and nothing else. B. Wind and volcanos.
C. Wind and earthquakes. D. Wind and water.
2.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.
3.The underlined word “succeeding” means__________.
A. reaching an aim B. doing well C. following after D. taking place
4.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.
