CNN News: 專家研究抗擊Zika方法 印尼天空上演350年一遇日全食

Zika, as we`ve told you, can dramatically harm the unborn babies of pregnant women. But mosquitoes also carry malaria, yellow fewer, West Nile virus. The insects are responsible for more human deaths than any other animal on the planet. And so far, people have been unsuccessful in exterminating them long term.

之間已經(jīng)提及過(guò)，Zika病毒會(huì)嚴(yán)重傷害孕婦腹中的嬰兒。但是蚊子也可以攜帶瘧疾，黃熱病以及西尼羅河病毒。這種昆蟲(chóng)所造成的人類死亡人數(shù)是最高的。但是截至到目前為止，人類尚不能長(zhǎng)期消滅蚊子。

Now, scientists are considering waging biological and genetic warfare against mosquitoes. One option would infect them with bacteria that would stop the growth of viruses, like Zika, inside mosquitoes. Another would use gamma radiation to sterilize male mosquitoes to keep them reproducing with females. A third possibility: genetically modified male mosquitoes to pass a deadly gene to wild female mosquitoes.

現(xiàn)在，科學(xué)家正在考慮對(duì)蚊子進(jìn)行生物和基因戰(zhàn)。其中一種選擇是，在蚊子體內(nèi)注射影響Zika病毒生長(zhǎng)的細(xì)菌。另一種是利用γ射線對(duì)雄性蚊子進(jìn)行絕育處理，使之無(wú)法與雌性蚊子交配進(jìn)行繁殖。第三種方法：轉(zhuǎn)基因蚊子將致命基因傳給野生雌性蚊子。

Critics say all of these ideas have major problems. They`re not proven to work. There are concerns about how they`d impact the environment, or the people living in it. An environmentalist with Emory University says it`s possible these methods could become useful tools, though not a silver bullet in fighting off man`s deadliest enemy.

評(píng)論家稱，所有這些想法有存在重大的問(wèn)題。因?yàn)檫@些方法尚未被證實(shí)。評(píng)論人員擔(dān)心這些措施會(huì)對(duì)環(huán)境以及生活在環(huán)境中的人造成何種影響。一位埃默里大學(xué)的環(huán)境學(xué)家稱，盡管這些方法在對(duì)抗人類這種致命敵人上不會(huì)立竿見(jiàn)影，但是這些方法將會(huì)成為有用的工具。

Call them stargazers, sun seekers, see the moonlights in their eyes. Thousands of people in the Pacific island nation of Indonesia looked up Wednesday morning to view a total solar eclipse. This is when the moon moves directly between the earth and the sun.

他們被稱為天文愛(ài)好者、追隨太陽(yáng)的人、觀看月亮變化。周三早上，在太平洋島國(guó)印度尼西亞，成千上萬(wàn)的人來(lái)觀看日全食。日全食時(shí)，月亮位于太陽(yáng)和地球之間。

The best view was on the Indonesian island of Sumatra, but the event was partially visible from Hawaii to Malaysia to Australia.

觀景的最佳地點(diǎn)是印尼蘇門(mén)答臘島，但是從夏威夷到馬來(lái)西亞以及澳大利亞部分地區(qū)也可以觀看到此景象。

The next total solar eclipse is expected on August 21st of next year, and would be visible in a narrow part of the U.S.

預(yù)計(jì)下次日全食出現(xiàn)的日期是明年8月21日，但美國(guó)只要一小部分可以觀看到此景觀。
