When prehistoric man arrived in new parts of the world, something strong happened to the large animals; they suddenly became extinct. Smaller species survived; the large, slow-growing animals were easy game, and were quickly hunted to extinction.
Now something similar could be happening in the oceans. That the seas are being over-fished has been known for years and researchers such as Ransom Myers and Boris Worm have shown how fast things are changing. They have looked at half a century of data from fisheries around the world. Their methods do not attempt to estimate the actual biomass (the amount of living biological matter) of fish species in particular parts of the ocean, but rather changes in that biomass over time. According to their latest paper published in Nature, the biomass of large predators (animals that kill and eat other animals) inanes fishery is reduced on average by 80% within 15 years of the start of exploitation. In some long-fished areas, it has halved again since then.
Dr. Worm acknowledges that these figures are conservative (保守的). One reason for this is that fishing technology has improved. Today’s vessels can find their prey using satellites and sonar, which were not available 50 years ago. That means a higher proportion of what is in the sea is being caught, so the real difference between present and past is likely to be worse than the one recorded by changes in catch sizes. In the early days, too, longlines would have been more saturated with fish. Some individuals would therefore not have been caught, since baited hooks would have been available to trap them, leading to an underestimate of fish stocks in the past. Furthermore, in the early days of longline fishing, a lot of fish were lost to sharks after they had been hooked. That is no longer a problem, because there are fewer sharks around noise.
Dr. Myers and Dr. Worm argue that their work gives a correct baseline, which future management efforts must take into account. They believe the date support an idea current among marine biologists, that of the “shifting baseline”. The notion is that people have failed to detect the massive changes which have happened in the ocean because they have been looking back only a relatively short time into the past. That matters because theory suggests that the maximum sustainable yield that can be cropped from a fishery comes when the biomass of a target species is about 50% of its original levels. Most fisheries are well below that, which is a bad way to do business.
1.The aim of the extinction of large prehistoric animals is to suggest that _______.
A．large animal were not easy to survive in the changing environment
B．small species survived as large animals disappeared
C．large sea animals may face the same threat today.

C．the catch sizes in new fisheries are only 20% of the original amount
D．the number of larger predators dropped faster in new fisheries than in the old
3.By saying these figures are conservative (line 1, paragraph 3), Dr worm means that_______.
A．fishing technology has improved rapidly
B．then catch-sizes are actually smaller then recorded
C．the marine biomass has suffered a greater loss
D．the date collected so far are out of date.
4.Dr Myers and other researchers hold that _______.
A．people should look for a baseline that can’t work for a longer time
B．fisheries should keep the yield below 50% of the biomass
C．the ocean biomass should restore its original level.
D．people should adjust the fishing baseline to changing situation.

A．management efficiency
B．biomass level

Have you ever heard of blogs (博客)? If you haven’t, you should have. It’s here, it’s growing and it’s having an influence on our life. Surf the Internet and you’ll find blogs everywhere. A blog, shortened from “weblog”, is a public Internet journal written by one person or a group of people. It is a website in which a person or a group can place news, personal thoughts, text, photos, video or audio files, or links upon which visitors can comment. A blog lets you post on the Internet without having to know web design or be technical. You are given an environment to make dated entries on the topic of your choice which are “published”, so other people can read them.
Authoring a blog, maintaining a blog or adding an article to an existing blog is called “blogging”. Blogging has revolutionized Internet publishing in the last several years because it gives everyone with Internet access the opportunity to become an online writer. Objects, such as “text and photos” in a blog can be called “blog posts”, “posts”, or “entries”. The person who posts these entries is called a “blogger”.
Now, somewhere around the world, a blog is created almost every 6 seconds. Because it’s great potential, Bill Gates views it as important as e-mail, BBS, and MSN. He’s trying to make blogs the important tools for future business communications.
