In October on the east coast of Australia migrating humpback whales pass very close to the shore. With the help of Max Egan, we went to film them near Byron Bay. It was extremely exciting to spot the little puffs of spray on the horizon. When migrating, the whales can be traveling at speeds of about 12km/h and can dive under anywhere between five and forty minutes, but with many years of experience Max usually guided our boat to exactly the right place to provide us with amazing sighting. As the whales break the surface like submarines , the water spills off their broad dark backs and huge tails. Then, with a powerful down stroke, they dive back into the depths of the sea, leaving just a smooth glassy patch of water or "footprint" on the surface to show where they had been. One day we had traveled up and down the shore and far out to the sea in search of whales, but the horizon was deserted. There was no report of whales in the area so we decided to test out Max's new, highly sensitive hydrophone and the result was astonishing. As soon as the hydrophone was in the water, we found ourselves listening to the most beautiful  voices. What may have seemed like a vast empty ocean was filled with the singing of whales. It is the males which sing, as they migrate between feeding and breeding grounds. No one knows for sure what the purpose of these songs is, whether they are love songs to the females or warnings to other males to stay away. It was thought that each population of humpbacks had its own song which remained regular but recent findings suggest that the whales appreciate a memorable tune and quickly adopt any new songs they hear. The writer's main purpose of looking for whales is  _  . A) carrying out research on whales B) studying the beautiful songs of whales C) making films about whales D) hunting whales for research

LONDON (Reuters) -- Children are dying for lack of drugs tailored to their needs, according to the World Health Organization (WHO), which launched a global campaign on Thursday to promote more research into child medicine. More than half of the drugs currently used to treat children in the industrialized world have not been specifically tested on youngsters. The problem is even worse in developing countries where price remains a major barrier and 6 million children die each year from treatable conditions. In the case of HIV/AIDS, the few existing pediatric therapies developed for children generally cost three times more than adult ones. As a result, clinicians lack clear guidelines on the best drug to use and often have to guess at the correct dose. Fortunately, the WHO has drawn up the first international List of Essential Medicines for Children, containing 206 products considered safe for children. "But a lot remains to be done. There are priority medicines that have not been adapted for children's use or are not available when needed," said Dr Hans, the U.N. agency's director of medicines policy and standards. Medicines that need to be adapted to children's needs include many antibiotics, pain drugs as well as combination pills for HIV/AIDS, tuberculosis and malaria. The agency is building an Internet entrance linking to clinical trials carried out in children and will launch a Web site with the information early next year. Testing medicines on children has always been a controversial issue, since good ethical practice requires informed agreement from people participating in clinical trials, which is difficult to obtain in the case of children. As a result, research-based drug companies have been _ of developing child-friendly medicines and general companies have been slow to produce them at lower cost. In an attempt to deal with the issue, both Europe and the United States now have special rules offering extended patent protection for drugs that have been tested on children. Why has testing medicines on children always been a controversial issue? A) It is against good ethical practice B) Children shouldn't take part in clinical trials. C) It is hard to get informed agreement from children tested. D) Parents don't allow their children to be tested on medicine.
