| 10 | Instead, there's really good recent research showing | 相反,最近有非常好的研究表明 |
| 11 | that mosquitoes, female mosquitoes specifically, since males don't drink blood, rely on four | 特别是蚊子 雌性蚊子 因为雄性不喝血 只能靠四只 |
| 12 | main signals to track down their targets, and as far as we know, none of them are your | 追踪目标的主要信号 据我们所知 他们都不是你的 |
| 13 | blood type. | 血型。 |
| 14 | The first is carbon dioxide, which, of course, animals exhale with every breath. | 第一种是二氧化碳, 当然,动物们用每一口气呼气。 |
| 15 | Mosquitoes can sense CO2 coming from as far as 30 meters away, triggering them to make | 蚊子能感知到距离30米的二氧化碳 引发它们制造 |

| 19 | Certain mosquitoes' visual systems are tuned to the specific wavelengths | 某些蚊子的视觉系统被调整到特定的波长 |
| 20 | common to human skin colors, and once they get close, within a meter or so, they rely | 人类皮肤颜色常见,一旦接近, 大约在一个表里,它们就依赖 |
| 21 | on body heat to home in on their tasty target. | 身体热到家 在他们美味的目标。 |
| 22 | But all humans breathe and are human-colored | 但是,所有的人呼吸 和人色 |

| 24 | more than others. | 比别人还要多 |
| 25 | I mean, if you're breathing a little faster or your temperature is a little | 我的意思是,如果你呼吸快一点 或者你的温度有点 |
| 26 | higher than everyone around you, like if you've been exercising, you might be a slightly more | 比你周围的每个人都高, 就像你一直在锻炼, 你可能是一个稍多一点 |
| 27 | attractive target, but a fourth signal is what really seems to separate mosquito magnets | 吸引人的目标,但第四个信号 似乎真正分离蚊子磁铁 |

| 30 | the way you smell to a mosquito. | 你闻到蚊子的味道 |

| 33 | some of which apparently smell irresistible to mosquitoes. | 有些蚊子闻起来很难抗拒 |
| 34 | One study found that mosquitoes | 一项研究发现蚊子 |

| 37 | And it turns out that your | 结果发现你 |
| 38 | particular combination of skin bacteria is mostly governed by your genes. | 皮肤细菌的结合 大多受你的基因支配 |
| 39 | That's why identical twins | 所以双胞胎 |

| 41 | twins who only share half of their genes. | 双胞胎只分享一半的基因 |
| 42 | And since you can't change your genes, you're more or less | 既然你无法改变你的基因 你或多或少 |
