The dogs sniffing out coronavirus 英國訓(xùn)練新冠肺炎檢測犬

學(xué)習(xí)要點(diǎn)

有關(guān) “smell（氣味）” 的詞匯

邊看邊答

Where are these Covid-19 sniffer dog trials taking place?

文字稿

This is Asher. He's a medical detection dog. Scientists are hoping specially trained dogs like Asher could be a vital help in the fight against Covid-19.

這是亞瑟。他是一只醫(yī)療檢測犬。科學(xué)家們希望像亞瑟這樣經(jīng)過特殊訓(xùn)練的犬在抗擊新冠肺炎疫情的戰(zhàn)役中起到至關(guān)重要的作用。

Dr Claire Guest, Medical Detection Dogs
The dogs have this incredible sense of smell. They have 350 million sensory receptors dedicated to olfaction. Now us poor humans have got five million and we think we can smell pretty well.

克萊爾·格斯特博士     英國慈善機(jī)構(gòu) “醫(yī)療檢測犬”（Medical Detection Dogs）
“這些狗的嗅覺極為靈敏。它們有3.5億個嗅覺感受器。而我們?nèi)祟愔挥形灏偃f個嗅覺感受器，我們還覺得自己的嗅覺不錯呢?！?

Asher's remarkable nose has already been trained to sniff out a number of human diseases like cancer and malaria. Now a joint research project with the London School of Hygiene and Tropical Medicine and Durham University is seeing whether they can detect Covid-19.

亞瑟嗅覺非凡的鼻子已經(jīng)過訓(xùn)練，可以嗅出一些人類疾病，比如癌癥和瘧疾?，F(xiàn)在，倫敦衛(wèi)生與熱帶醫(yī)學(xué)院及杜倫大學(xué)共同開展了一項(xiàng)研究項(xiàng)目，評估這些狗能否檢測出新冠病毒。

Professor James Logan, London School of Hygiene and Tropical Medicine
We now know, scientifically, that diseases change body odour, and, you know, dogs are incredibly good at sniffing – and we all know that – but they're also very good at learning as well. And so they can learn the smell of a particular medical condition. We now know that dogs really can do this really well, so we're really hopeful that the dogs will be able to do this with Covid-19.

詹姆斯·洛根教授     倫敦衛(wèi)生與熱帶醫(yī)學(xué)院
“科學(xué)表明，疾病會改變體味，而且狗非常擅長嗅氣味，這一點(diǎn)眾人皆知，但同時狗也很善于學(xué)習(xí)。這樣它們就能記住特定疾病的氣味。我們知道狗能記住疾病氣味，因此非常希望狗也能記住新冠病毒的氣味。”

Helsinki airport in Finland. Trials have already started here, with dogs sniffing passengers as they arrive. This is Kip – one of the dogs being trained to detect Covid-19. He lives with Sam.

這是芬蘭的赫爾辛基機(jī)場。試點(diǎn)試驗(yàn)已在這里展開，乘客到達(dá)后，檢測犬便開始聞他們身上的氣味。這是基普，一只正在接受檢測新冠病毒訓(xùn)練的狗?；蘸蜕耗纷≡谝黄?。

Sam Ferguson, dog owner
I think it is a fantastic project. The capability of dogs to do mass screening in a speedy time is really, really important because Covid's going to be with us for a while yet, so they have a massive part to play.

珊姆·弗格森     狗主
“我認(rèn)為這是一個很棒的項(xiàng)目。狗在短時間內(nèi)進(jìn)行大規(guī)模篩查的能力是極為可貴的，新冠肺炎疫情仍將持續(xù)一段時間，所以狗能起到很大的作用?！?

The dogs are trained by sniffing samples of clothing from people who currently have Covid-19. Researchers say they desperately need more samples and are appealing for help.

訓(xùn)練檢測犬的方法是嗅探目前感染新冠病毒的人穿過的衣物樣本。研究人員們表示，他們急需更多的樣本，正在尋求幫助。
