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  . 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... We can infer from Dr Myers and Dr. Worm's paper that   _  . A) the stock of large predators in some old fisheries has reduced by 90% B) there are only half as many fisheries are there were 15 years ago 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

High heels, coffee cups and dogs have been regarded as three of the most dangerous things to have in a car. The seemingly harmless items have been responsible for more than 13 million crashes and near misses on Britain's roads. While men were responsible for the greater number of accidents reported, women played their part by driving in high heels. Putting fashion over function meant 44 percent of female motorists had been prevented from using the pedals correctly by their high heels--with those aged 25 to 34 accounting for most of the incidents reported. Those keen for a caffeine kick while driving can also create an accident if they leave empty coffee cups lying around their vehicle. Twenty percent of those surveyed admitted they had crashed their car or had a near miss after a deserted coffee cup or empty drink bottle rolled under their brake pedal . However, it is not just wearing and eating that cause a threat from inside the car, man's best friend could also cause a catastrophe if not safely secured. One in eight motorists claimed to have had a scrape or near miss on the road due to their dog's wandering freely, climbing into the front seat or trying to escape through the windows. The accidents meant drivers took their eyes off the road for more than three seconds each time, according to the poll of 2,000 British motorists. The survey has found drivers will pick up an average bill of PS261.47 for the damage caused by every crash. Londoners were the most at risk of an accident closely followed by motorists in the West Midland and Wales. Janet Connor, a managing director, said many accidents could be avoided if people cleaned their cars regularly, as one in ten drivers involved in crashes admitted to driving inside a mountain of debris. She said, "The possible dangers and distractions outside the car are well known but as the evidence suggests, those within the car are often forgotten." We can mainly learn from the passage that   _  . A) only 10% of the drivers remember to keep their car clean B) people often neglect the dangers outside the car C) dangers within the car should be given more attention to D) accidents can be avoided if cars are cleaned regularly

Q: There are three ways you can go about writing a resume: You can rely solely in your memory; you can dust off  a previous resume and add something new to it ;or you can create a new resume from a permanent personal data record .If you don't have a personal data record, prepare one now.

Compared to the other parts of the body, our ears don't ask for much. They don't need to be brushed once a day like your teeth. But they need some special care, especially if you like listening to music with earphones. Maybe your mum or dad has told you, "Turn that down before you go deaf!" Well, they are quite right. Loud noise might cause hearing loss for a short time or even forever. Think that earphones are a good way to escape from tour parents' eyes? Well. It may not be as good a way as you expect. American doctors have studied a group of 44,000 people who used earphones more than 15 hours per week. The doctors found that 37,000 of them were getting hearing problems. If you use earphones for too long a time, your ears might feel painful. You could also lose your hearing for the rest of your life. So don't wear your earphones too long. Use them less than one hour a day. Want sharp hearing? Don't forget to do the following: Try to stay away from places where there is too much noise, like a disco. If you have to go, wear earplugs. When swimming, remember to put earplugs into your ears to stop water from getting in. Never put anything sharp into your ears. If you think you have too much earwax, ask your mum or dad to help you clean it out. Keep these things in mind! Then you won't be saying "WHAT???" when you are older. Using earphones "may not be as good a way as you expect" because   _  . A) your parents know what you're doing B) it can cause hearing problems C) it makes your parents angry D) most of you use them improperly
