E．Paragraph
　　The mosquito is the most dangerous insect in the world, and can be shown to be man’s oldest and deadliest insect enemy. According to the Guinness Book of Records, the type of mosquito which carries malaria and other diseases is believed to be responsible, directly or indirectly, for half of all human deaths since the Stone Age, if you exclude deaths from wars and accidents. Even today, mosquitoes kill up to two million people a year worldwide, and an estimated 600 million more are said to be at risk or threatened by the diseases they carry.
　　Infection is carried only by the female mosquito, which usually has to feed on blood before laying eggs. The insect injects the victim with a substance which thins the blood, before it is sucked up through a needle-like tube on its head. The thinning agent contains the disease, which will then be passed on to the next person by this mosquito. And so proceeds the vicious cycle of disease and death.
　　As quickly as we develop insecticides to kill them, mosquitoes seem to be able to develop resistance to our inventions. The same is true of efforts to develop drugs to control the diseases spread by mosquitoes. In many cases, it takes a much shorter time for mosquitoes to develop resistance to man’s invention of a new drug than it takes man to develop the drug.
