This site , all-birds. com, is about bird watching. Enjoy your browsing. There is much to learn and see.
Bird Watching Equipment
Some items that might make bird watching more enjoyable are binoculars ( 雙目望遠(yuǎn)鏡) , a camera, some kind of system for keeping notes, and maybe a back pack. Birders often keep lists of the birds they see along with notes about the habits. There is some great bird log software that will let you keep records on your computer. For more details on choosing binoculars see our Binocular -Optics page.
Clothes
If you are walking through a wooded area just wear clothes you would wear on any hike or field trip. You are best off wearing clothes with dull colors that mix into the background. Greens, browns, and grays are good. Avoid fabrics that rustle(沙沙響)easily. Depending on the birds you are watching you may want to get rain gear, rubber boots and warm clothing. For birds such as owls that you might look for in the evening a strong flashlight is also handy.
Choosing a Bird Field Guide
Take a good field guide to identify birds. Look for clear color pictures that make it easy to recognize one bird from another. Next to each picture should be detailed descriptions of each bird's anatomy, habits, and what it eats. The guide should have information about what habitat each species uses. Many guides have maps showing the range of different birds along with their migration patterns.
Where and When to see Birds
Learning the habitats of birds in your area will increase the number of birds you see, and make your birding more enjoyable. If you know that Meadow larks are likely to be in open grassy areas, and dippers are forage along stream beds, you may be looking for them if you are in those types of habitats. Edge areas where different types of habitats meet will likely have more species in them. You are more likely to see specific birds at certain times of the day. For example songbirds are easier to see two to three hours after dawn, or just before sunset. This is when songbirds are most actively feeding. Many small birds will be silent or even hidden during the rest of the day. After sunup is the best time to see eagles and hawks. Visibility is best for hunting at this time, and they can soar on the thermal currents from the warmed air. Birds like owls are more likely to be seen in the evening. Many shorebirds and waders rest at high tide and feed when the water rises or falls.
Photographing Birds
Patience in Bird Photography
Most birds are afraid of people, and all species have their own comfort zone. With a little time you can learn the comfort zone of the birds you are photographing. Once they know that you are not a threat you may be able to get closer.
Type or Style
Your reason for photographing birds may determine your style and the kind of equipment you use. If you are just recording the kinds of birds you see you don't need to get as close, and you can use less expensive equipment, then you need for high quality prints.
Photographing Birds in Flight
Photographing birds in flight can be fun. Many digital cameras have a tracking function. With these you focus on the bird, and then as you track it the lens will keep focus.
Use Your Yard
Choose an open area where the birds will get direct sunlight, showing off their magnificent colors.
Try using props
Birds will often land on a stick or post near a seed feeder before going to the feeder. The background was just an out of focus fence but you can use anything you want for a background, and then wait for a bird to perch.

Is your family interested in buying a dog? A dog can be a pleasant companion(伙伴) to your family, but if you choose the wrong kind of dog,you will have a lot of troubles.
Families should sit down and thoroughly discuss the possible problems before buying a dog. Even if the children in your family are the ones who want the dog, the parents are the ones who are really responsible for seeing that the animal is properly cared for. If you don’t know much about dogs, it is a good idea to go to the library for books about different kinds of dogs, as well as books about how to train a young dog. In reading about the different breeds(種類)you should know that a dog described(描述)as very alert(機(jī)敏靈活的)may be too active. When a book describes a dog as an excellent hunting dog, it probably means that the dog won’t be happy living in a small house. Dog breeds vary(變化)in popularity as the years go by. One of the most popular dogs these days is the German shepherd(牧羊犬). This is because it provides protection as well as companionship(陪伴). The family should be warned that these dogs grow up to be very big, and may be too powerful for children to control. If space is limited, a toy dog may be a good choice. These dogs are very small and easy to train. They don’t need to be walked daily, since they can exercise in the home.
【小題1】According to the passage, one can get information about different kinds of dogs .
A.by going to the library |
B.by asking someone who has enough experience about different kinds of dogs |
C.by buying a dog and training it |
D.by reading books about dogs |
A.because it is easy to train |
B.because it is big and strong |
C.because it is powerful and friendly |
D.because it is alert and active |
A.The care and proper selection of dogs for families. |
B.Different breeds of dogs. |
C.Responsibility for seeing that dogs are properly cared for. |

Look, this is the first plane in the world to be created using the new technology of “3D printing”. The airplane was built using only a computer—but it can fly at a speed of 100mph and has a two-meter wingspan.
It was produced using a special nylon laser printer that builds up something layer-by-layer. The parts were made separately and attached using a “snap fit” technique so the aircraft could be put together without tools in minutes.
No fasteners at all were used in the manufacture of the plane. Unmanned and electrically powered, the plane can travel in near silence and is also equipped with a small autopilot system. The special production process used is known as “l(fā)aser sintering(激光燒結(jié))”and allows the designers to create shapes and structures that would normally include costly manufacturing techniques. This technology allows a highly-tailored aircraft to be developed from your own design to first flight in days, while using traditional materials and techniques would take months. And because no tooling is required for manufacture, major changes to the shape and scale of the aircraft can be made with no extra cost.
Professor Jim Scanlon, who led the team, said, “The process allows the design team to revisit historical techniques and ideas that would have been too expensive using traditional manufacturing.” He added, “This form of structure is very firm and lightweight, but very complex. If it was manufactured traditionally it would require a large number of individually tailored parts that would have to be connected or fastened at great expense.”
The new printed plane is known as the Southampton University Laser Sintered Aircraft—or SULSA for short—and is part of a wider project using cutting-edge manufacturing techniques. The University of Southampton has been at the leading position of Unmanned Aerial Vehicle development since the early 1990s.
【小題1】Which of the following would be the best title for the text?
A. Revolutionary Breakthrough of 3D Printer
Scientists Create Aircraft with High Speed
C. New Designed Airplane with New Techniques.
D. The World’s first 3-D printed Airplane, SULSA
【小題2】How could the plane work while flying?
A.It should be controlled by an autopilot system. |
B.It should be controlled by “l(fā)aser sintering”. |
C.A pilot controls it using a remote control. |
D.A pilot with high techniques controlled it. |
A.it produces little noise while flying |
B.it is manufactured in quite a short time |
C.it only requires simple and cheap tools |
D.it needn’t extra cost if changes are made |
A.produce firmer and lighter real planes easily |
B.connect and fasten tailor parts for real planes |
C.copy earlier planes to study their techniques |
D.find differences by studying the traditional ones |

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.
Diet products 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(卡), unhealthy foods. Diet products allow us to jump over the thinking stage and go straight for the counter instead. All we have to do is to swallow or recognize the word “diet” in food brands.
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(營養(yǎng)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.
【小題1】The first paragraph mainly tells us _____.
A.diet products can bring out people’s potential |
B.people have difficulty in choosing diet products |
C.diet products are misleading people |
D.people are fed up with diet products |
A.resist a variety of diet foods |
B.hesitate before they enjoy diet foods |
C.pay attention to their own eating habits |
D.watch their weight rather than their diet |
A.to warn people of the side effect of diet products |
B.to tell people how to lose weight |
C.to advise people to eat diet products |
D.to introduce some diet products |

Eating too much fatty food, exercising too little and smoking can raise your future risk of heart disease. But there is another factor that can cause your heart problems more immediately: the air you breathe.
Previous studies have linked high exposure (暴露)to environmental pollution to an increased risk of heart problem, but two analyses now show that poor air quality can lead to heart attack or stroke (中風(fēng))within as little as a few hours after exposure. In one review of the research, scientists found that people exposed to high levels of pollutants (污染物)were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA) considers to be of “moderate” (良好)quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure.
The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.
【小題1】The text mainly discusses the relationship between ______ .
A.heart problems and air quality | B.heart problems and exercising |
C.heart problems and smoking | D.heart problems and fatty food |
A.relatively high | B.extremely low |
C.relatively low | D.extremely high |
A.Eating fatty food has immediate effects on your heart. |
B.The EPA conducted many studies on air quality. |
C.Moderate air quality is more harmful than smoking. |
D.Stricter regulations on pollutants should be made. |
A.inform | B.persuade | C.describe | D.entertain |

Animals seem to have the sense to eat when they are hungry and they do not eat more than their bodies need. It has been shown that rats will, when given a choice over a period of time, prefer water with vitamins(維生素) to water without vitamins, even though there is no difference in taste or smell between the two water bottles. When a sweet smell was added to the vitamins-enriched water, the rats did seem to develop a taste for it and kept drinking it, even after the vitamins were changed to the clear water. In time(最后), however, they broke the habit and went back to where the necessary vitamins were.
In experiments, babies of 6 to 12 months old were placed in a room with many choices of baby food before them. They were given whatever food they pointed to or appeared interested in. We are told that at first they showed some unusual eating habits, but over a period of time they managed to choose a well-balanced diet.
So in choosing food, rats and babies do seem to know what's best for them. Clearly, there is a kind of “body wisdom”, which humans soon lose. Most of us do not eat as wisely as we could. Many of our food preferences are culturally determined and influenced by old habits. Some people eat foxes, dogs and blackbirds, while we eat cows and pigs. So what people eat and how much they eat seem to be greatly influenced by what is going around them.
【小題1】 In the experiment on rats, a sweet smell was added to the rats’ drinking water to ________ .
A.encourage rats to drink vitamins-enriched water |
B.test whether rats know which drink is good for them |
C.find out rats’ preference in flavor(口味) |
D.show the vitamins are tasteless |
A.both have the wisdom to choose a balanced diet |
B.both prefer flavored food and drink |
C.both have the same eating habits |
D.both develop a taste for the same kinds of food |
A.given many choices of drinks |
B.placed and fed in a hospital |
C.given all kinds of baby food |
D.trained to select a balanced diet |
A.they know better than babies what kinds of food are good for their health |
B.they usually cannot say no to all kinds of delicious foods |
C.their eating habits have much to do with the social and cultural customs |
D.they have more choices of food than babies in eating patterns |

The year is 2094. It has been announced that a comet is heading towards the Earth. Most of it will miss our planet, but two pieces will probably hit the southern half of the Earth.
On 17 July, a piece four kilometers wide enters the Earth’s atmosphere with a massive explosion. About half of the piece is destroyed, but the remaining part hits the South Atlantic at 200 times the speed of sound. The sea boils and a huge hole is made in the sea bed. Huge waves are created and spread outwards from the hole. The wall of water, a kilometer high, rushes towards southern Africa at 800 kilometers an hour. Cities on the African coast are totally destroyed and millions of people drowned.
Before the waves reach South America, the second piece of the comet lands in Argentina. Earthquakes and volcanoes are set off in the Andes Mountains. The shock waves move north into California and all around the Pacific Ocean. The cities of Los Angeles, San Francisco and Tokyo are completely destroyed by earthquakes. Millions of people in the southern half of the Earth are already dead, but the north won’t escape for long. Because of the explosions, the sun is hidden by clouds of dust, temperatures around the world fall to almost zero. Crops are ruined. The sun won’t be seen again for many years. Wars break out as countries fight for food. A year later, no more than 10 million people remain alive.
Could it really happen? In fact, it has already happened more than once in the history of the Earth. The dinosaurs were on the Earth for over 160 million years. Then 65 million years ago they suddenly disappeared. Many scientists believe that the Earth was hit by a piece of object in space. The dinosaurs couldn’t live through the cold climate that followed and they died out. Will we meet the same end?
【小題1】What is mainly described in the passage?
A.A historic discovery. | B.An event of imagination. |
C.A research on space. | D.A scientific adventure. |
A.a(chǎn)n earthquake | B.damages to cities |
C.a(chǎn)n Earth explosion | D.huge waves |
A.Because the land is covered with water. |
B.Because the light and heat from the sun can not reach the Earth. |
C.Because people there can not live at the temperature of zero. |
D.Because wars break out among countries. |
A.a(chǎn)nimals could not live in the cold climate |
B.what happened 65 million years ago was an invented story |

People have always been dreaming of going to the moon. As long as the year 1901, H. G. Wells, an English writer, wrote a book vividly describing a trip to the moon. On landing there, the explorers discovered that the moon was full of underground cities. Words failed to express their surprise when they spotted so many “moon people”. The “moon people” felt even more surprised. “Why,” they asked, “are you traveling to outer space when you don’t even use your inner space?”
H. G. Wells could only imagine a travel to the moon. In 1969, human beings really left their footsteps on the moon. People today know that there are no underground cities on the moon. However, the question that the “moon people” asked is still an interesting one. A growing number of scientists are seriously thinking about it.
Underground systems are already in place. Many cities have underground car parks. In some cities, such as Tokyo, Seoul and Montreal, there are large underground shopping areas. The “Channel”, a tunnel connecting England and France, is now complete.
But what about underground cities? Japan’s Taisei Corporation is designing a network of underground systems, called “Alice Cities”. The designers imagine using surface space for public parks and using underground space for flats, offices, shopping, and so on. A solar dome (太陽能穹頂) would cover the whole city.
Supporters of underground development argue that building down rather than building up is a good way to use the earth’s space. The space, they say, can be used for farms, parks, gardens, and wilderness. H. G. Wells’ “moon people” would second it. Would you?
【小題1】The explorers in H. G. Well’s story were surprised to find that the “moon people” .
A.knew so much about the earth |
B.understood their language |
C.lived in underground cities |
D.were advanced in technology |
A.Discovering the moon’s inner space |
B.Using the earth’s inner space |
C.Meeting the “moon people” again |
D.Traveling to outer space |
A.Offices, shopping areas, power stations. |
B.Tunnels, car parks, shopping areas. |
C.Gardens, car parks, power stations. |
D.Tunnels, gardens, offices. |
A.H. G. Wells once went to moon himself. |
B.Underground cities are more comfortable. |
C.The solar dome is a necessary part of underground cities. |
D.More underground systems will be in place in 2013. |
A.Alice Cities — cities of the future |
B.Space travel with H. G. Wells |
C.Enjoy living underground |
D.Building down, not up |

Over a period of time, many habitats (棲息地)change with respect to the types of plants and animals that live there. This change is known as succession.
Succession occurs because plants and animals cause a change in the environment in which they live. The first weeds and grasses that appear on a bare field, for example, change the environment by shielding the soil from direct sunlight. As these plants spread, the ground becomes cooler and more moist than it was originally. Thus, the environment at the ground surface has been changed. The new surface conditions favor the sprouting(產(chǎn)生)of shrubs. As shrubs grow, they kill the grasses by preventing light from reaching them and also enhance (增加)the soil. Pine seedlings (苗)soon take hold and as they grow, they in turn shade out the shrubs. They are not able to shade out oak and hickory (山核桃)seedlings, however, that have found the forest floor suitable. These seedlings grew into large trees that eventually shade out the pines.
【小題1】The best title of this passage is _____.
A.The Importance of Weeds and Grasses |
B.The Success of Oak and Hickory |
C.How Environmental Habitats Change |
D.Animal and Plant Habitats |
A.oak and hickory trees grow taller than pines |
B.weeds and grasses prefer cold climate |
C.pines and grasses can exist together |
D.birds encourage the growth of shrubs |
A.A forest cut down to build an airport. |
B.A flood washing away a crop of wheat |
C.Wild flowers growing in an unused parking lot |
D.Animals being tamed (馴服)by children |
