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 （ 双目望远镜） , 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（沙沙响）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.

The world's oceans have warmed 50 percent faster over the last 40 years than previously thought due to climate change, Australian and US climate researchers reported on Wednesday. Higher ocean temperatures expand the volume of water, contributing to a rise in sea levels that is submerging small island nations and threatening to great damage in low-lying, densely-populated delta regions around the globe.

The study, published in the British journal Nature, adds to a growing scientific chorus of warnings about the pace and consequences of rising oceans. It also serves as a corrective to a massive report issued last year by the Nobel-winning UN Intergovernmental Panel on Climate Change（IPCC）, according to the authors.

Rising sea levels are driven by two things: the thermal（热）expansion of sea water, and additional water from melting sources of ice. Both processes are caused by global warming. The ice sheet that sits at the top of Greenland, for example, contains enough water to raise world ocean levels by seven metres（23 feet）, which would bury sea-level cities from Dhaka to Shanghai.

Trying to figure out how much each of these factors contributes to rising sea levels is critically important to understanding climate change, and forecasting future temperature rises, scientists say. But up to now, there has been a confusing gap between the projections of computer-based climate models, and the observations of scientists gathering data from the oceans.

The new study, led by Catia Domingues of the Centre for Australian Weather and Climate Research, is the first to reconcile（与…一致）the models with observed data. Using new techniques to assess ocean temperatures to a depth of 700 metres（2,300 feet）from 1961 to 2003, it shows that thermal warming contributed to a 0.53 millimetre-per-year rise in sea levels rather than the 0.32 mm rise reported by the IPCC.

64. What happens when the ocean's temperature rises?

A. It causes sea levels to rise.

B. It causes sea levels to remain constant.

C. It causes sea levels to decrease.

D. It causes sea level to change.

65. Which of the followings would be buried by the rising sea?

A. Small island nations.

B. All coastal cities around the world.

C. People who enjoy holiday on the beach.

D. Low-lying regions.

66. The new study in this passage _____________.

A. shows that thermal warming contributed to a 0.32 millimeter-per-year rise in sea levels.

B. did not reveal anything that scientists hadn't already known.

C. used new techniques to assess ocean temperatures.

D. shows that models contradict the observed data.

67. What was the main finding of the study?

A. Nothing enough is being done about global warming.

B. That ocean waters have warmed faster than scientists had previously thought.

C. That the warming of the world's oceans is not a threat.

D. A massive report issued last year by IPCC was wrong.

Passage ten(Antinuclear Demonstration)
Police fired tear gas and arrested more than 5,000 passively resisting protestors Friday in an attempt to break up the largest antinuclear demonstration ever staged in the United States. More than 135,000 demonstrators confronted police on the construction site of a 1,000-megawatt nuclear power plant scheduled to provide power to most of southern New Hampshire. Organizers of the huge demonstration said, the protest was continuing despite the police actions. More demonstrators were arriving to keep up the pressure on state authorities to cancel the project. The demonstrator had charged that the project was unsafe in the densely populated area, would create thermal pollution in the bay, and had no acceptable means for disposing of its radioactive wasters. The demonstrations would go on until the jails and the courts were so overloaded that the state judicial system would collapse.
Governor Stanforth Thumper insisted that there would be no reconsideration of the power project and no delay in its construction set for completion in three years. “This project will begin on time and the people of this state will begin to receive its benefits on schedule. Those who break the law in misguided attempts to sabotage the project will be dealt with according to the law,” he said. And police called in reinforcements from all over the state to handle the disturbances.
The protests began before dawn Friday when several thousand demonstrators broke through police lines around the cordoned-off construction site. They carried placards that read “No Nukes is Good Nukes,” “Sunpower, Not Nuclear Power,” and “Stop Private Profits from Public Peril.” They defied police order to move from the area. Tear gas canisters fired by police failed to dislodge the protestors who had come prepared with their own gas masks or facecloths. Finally gas-masked and helmeted police charged into the crowd to drag off the demonstrators one by one. The protestors did not resist police, but refused to walk away under their own power. Those arrested would be charged with unlawful assembly, trespassing, and disturbing the peace.

D.Disposal of wastes.
4.With whom were the jails and courts overloaded?
A.With prisoners.
B.With arrested demonstrators.
C.With criminals.
D.With protestors.
5.What is the attitude of Governor Stanforth Thumper toward the power project and the demonstration?
