But originally, much of the medicine developed in the last century came from natural sources: plants or bacteria. Now, a group of scientists in Great Britain are hoping to develop a medicine from poisonous insects. They are researching whether the deadly venom（毒液）of some insects can work against bacteria.Venom tech laboratoryAbout 400 insects live in plastic containers in the Venomtech laboratory. Each container has an image of a skull and crossbones. The images warn that a bite from the insects inside can be anything from painful to deadly.The venom from these insects contains hundreds of chemical components. Each component has a different target and effect. Medical researchers separate the venom into its component parts. Then they create a library of those components, looking for the ones that could be turned into new drugs. “Some of them we found can kill bacteria, like E Coli, so theyre very relevant at the moment where modern medicines are failing. And were also finding venom that is changing and killing cancer cells.”Finding new ways to kill bacteria is important to researchers. One reason is that people have used antibiotics (抗生素)so much that some bacteria can now resist it. For example, tuberculosis used to be curable with antibiotics. Now it is not. How do they get the venom out? To get as much venom as possible, researchers feed the insects well and then put them to sleep temporarily. Steven Trim of Venomtech says researchers anaesthetize the insects to make removing the venom safer. After all, an immobile insect cannot bite. Researchers then electrically stimulate the insect to contract(收缩)the muscle and squeeze the gland(腺). The pressure produces a small amount of venom. Researchers separate the venom into hundreds of proteins. Each protein contains between one and five different molecules (分子). Someday, those tiny molecules might be turned into powerful new drugs.1.

The chemical components from venom can be turned into new drugs.4. The researchers get venom from poisonous insects by _.A. making them sleep for some time B. squeezing the gland containing antibiotics C. separating the venom into proteins D. stimulating the insects to relax the muscleB A woman was walking her dog along a beach in New Zealand in late June when she saw something that looked like a white ball in the sand. It turned out to be a young Emperor Penguin that was lost. At his age，he should have been close to the Antarctic，swimming for fish and playing on the ice floes(冰川)But this penguin started swimming north and just kept going.The penguin attracted a lot of attention in New Zealand. It has been 40 years since an Emperor Penguin was last seen there. Researchers at the Department of Conservation were called in. They decided to watch the penguin closely，but not to disturb it in any way. Many New Zealanders came to Peka Peka Beach to look at the elegant penguin. They were careful to keep their dogs away from him so he wouldnt be frightened.The public nicknamed the animal Happy Feet. Researchers started to notice that Happy Feet didnt seem well. It turned out that he had been eating the sand from the beach，likely thinking it was snow.The public raised more than 11,000 pounds for an operation to get the sand out of his stomach. The operation was a success，and Happy Feet was taken to a zoo in Wellington，NZ.A group of experts met to decide how to help Happy Feet return to the wild.Last Sunday，they put him on a boat called the Tangaroa，in a specially built icefilled box and took him out into the Southern Ocean，southeast of New Zealand. There，they released him into the ocean，which is his natural habitat. He took one last look at his human helpers and then dived into the ocean.“Emperor Penguins spend their first five years at sea，” said Peter Simpson of New Zealands Department of Conservation.“What happens now is up to the penguin.”Happy Feet was fitted with a satellite transmitter(发射机) so they can monitor his progress using the Internet. So far，the trackers show that he swam nor
