【文章內(nèi)容簡(jiǎn)介】 t its saliva (唾液) contains a protein that acts as a vaccine against leishmaniasis, a deadly disease that leads to terrible skin problems. The team confirmed that mice bitten by the geneticallyengineered mosquito developed an antibody to the disease, meaning they had built up immunity (免疫力). “You would be vaccinated without even noticing. You wouldn’t need any drug and you wouldn’t need to show up at a fixed place for mass vaccinations,” said Shigeto Yoshida, the associate professor who has led the research. “Repeated bites would only strengthen the immunity.” Similarly the mosquitoes could be used to help treat malaria (瘧疾), perhaps a decade from now, said the malaria expert. Nearly one million people die each year from malaria — most of them children — mainly in Africa and Asia, according to the World Health Organization. Now a problem is that no effective vaccine exists. “There is a treatment that works, but it is beyond the reach of people who need to worry about food for tomorrow,” Yoshida said. However, Yoshida expects that the geneticallyengineered mosquito will finally help wipe out the deadly disease in the developing world. “Technically speaking, I believe it’s a matter of 10 years or so, but it’s not clear whether society would accept it,” he said.Another problem is that the geneticallyengineered mosquito may still pick up and spread the infected blood of a person who has already caught malaria. Yoshida’s team is hoping it can solve this problem by developing a mosquito species that kills the malaria virus inside its own body.31.

Ambiguous CIn this life, there are many opposite things, which cannot be united by many people. But there is always a chance to unite two different things in one work. The following passage will tell you more about the possibility of bining painting and poetry. Perhaps, it is not a new idea that a great work can be created by bining paintings and poems. In this case, we can unite both things in two ways. The first way is to make the poem as the main inspiration for the is also possible to write a poem after looking at a painting. What about the next idea to bine painting and poetry? Well, we can bine both of them on a canvas. You can paint an oil painting on it and then write down the poem on that canvas. I do not know whether this kind of idea has been used for years. But this is quite a great new idea for me. It will make more people love painting and poetry at the same time. You will not need to read the poem on plain white cloth anymore.A poem is a good way to represent a story or a thought. It is usually not too long and not easy to be understood li
