remarkable pictures. Under the sea, deep in the woods and high in the sky, furry, feathery and leathery-skinned
creatures are opening up vistas (远景) by taking cameras where no human can go.
This is the world of animal-borne imagine celebrated last month at a conference sponsored(supported) by
the National Geographic Society for the 20th anniversary of its Crittercam, the device that started it all.
Since its debut (首次公开露面) in 1987 on the back of a turtle, the Crittercam and similar devices
developed by others have grown smaller and more powerful.
"It's more than just a camera now," said Greg Marshall, the marine biologist and now filmmaker who
invented the Crittercam."We are now including more instruments to gather more data while at the same time
The idea of attaching video cameras to animals came to Mr. Marshall in 1986 on a dive off Belize when a shark
apporoached him. When the animal quickly turned away, he noticed a shark with a sucker fish on its belly. He
came up with the idea that putting a camera in place of the sucker fish would allow people to witness the
shark's behavior without disturbing it.
Crittercams have been attached to sharks, sea lions and other marine animals, and, more recently, to land
animals.
Birds are a new addition, Mr.Marshall said. Dr. Christian Rutz of Oxford recently reported on tiny cameras
called feathercams that monitor the crows in the South Pacific. It has discovered that crows are smarter than
anyone knew they not only use twigs (嫩枝) and grass stems as tools to root out food, but they also save their
favorite tools to use again.
Tracey L.Rogers, director of the Australian Marine Mammal Research Center in Sydney, said crittercam
was a powerful tool in her work with leopard seals (豹斑海豹) in Antarctica. "In studying animals," Dr.
Rogers said at the meeting,"you want to see how our animal models align (与……一致) with reality. With a
camera, you actually see what they do. You don't have to guess."
A. The advantages of crittercam.
B. The development of Crittercams in the past 20 years.
C. How crittercam was invented.
D. How crittercam works.
B. The thought of how to photograph animals better.
C. Noticing a shark eating a sucker fish on a dive.
D. Seeing a shark with a camera on its belly on a dive.
B. is the most powerful tool in studying animals
C. enabled her to observe the crows in the South Pacific closely
D. helped a lot with her research on leopard seals in Antarctica
B. more instruments are involved to gather more data
C. they allow researchers to see where and how animals live
D. they are able to be applied to smaller animals such as birds

| When you are in a place where you are hunting for a new job or career, you will find that there are several things needing your atten tion. Jobs and careers are fewer than you might entirely be prepared for; especially when satisfying employment is something you need to seriously think about. How are you going to find the job that you want and how are you going to avoid traps in your way? When you want to make the most out of your job search, take a moment and think about the things that you must avoid at all costs. One of the most important rules is, never to compromise on your requirements such that it will negatively affect your life and peace of mind at a later stage. Keep in mind your basic expectations from a job. It might be something along the lines of increased monetary pay ment or you might find that it has something to do with benefits or time off. Whatever it is that you count as your basic requirements, make sure that you do not accept a job without it. Your requirements might be difficult to get, but you have all the rights to try and a chieve them. That being said, don't shy away from odd jobs that might actu ally take you to the place that you want to be in, eventually. Some- times, finding the right job is a matter of luck and chance after you have been searching and putting in a lot of efforts. And if something unexpected happens, remember that taking chances is something you might want to seriously consider. You are in a place where you are thinking about moving forward, so don't be surprised by what route it might take to get there. As long as you keep your goals in mind, you are going to be doing much better than other people are during their job search. If you are looking for the right career, another thing that you can do to make sure that you get the right kind of employment is to advertise yourself. When you do nothing to push yourself forward, you will be the one suffering for it. If required, motivate yourself and try to look at all that you possess by way of positive traits. Make sure that you can present your skills and abilities in the best light possi ble. If the jobs that you have set your sights on are challenging, set targets for yourself and work towards them in a systematic and fo cused manner. The more efforts you put into marketing yourself, the better will be your chances of obtaining the job of your choice. Remember that when you are working on a job search, you should not shortchange yourself. This is because you will only hurt yourself by aiming low. What to avoid during your job search | ||||||||
