最新一項(xiàng)研究表明，在極端溫度下工作的孕婦，熱應(yīng)激可能會(huì)對(duì)她們腹中的胎兒產(chǎn)生影響。其影響包括胎兒心率加快和臍帶血流減慢。

This study monitored pregnant women who were working in rice fields in The Gambia. They were farming in direct sun for between two to eight hours, often in high humidity.

Researchers from the London School of Hygiene and Tropical Medicine say as a mother worked in the extreme heat the heart rate of the unborn child increased to dangerous levels. They also found the blood flow to the foetus slowed as the placenta was impacted by the heat.

倫敦衛(wèi)生與熱帶醫(yī)學(xué)院的研究人員表示，當(dāng)孕婦在極端高溫環(huán)境下工作時(shí)，胎兒的心率會(huì)上升到危險(xiǎn)水平。他們還發(fā)現(xiàn)，由于胎盤(pán)受到高溫的影響，流向胎兒的血流減慢。

Scientists say this is the first real-world study looking at the impact of extreme heat on pregnant women in low-income countries. They are calling for more research as so many places now face rising temperatures.

科學(xué)家們稱，這是第一次在現(xiàn)實(shí)世界中研究極端高溫對(duì)低收入國(guó)家孕婦的影響。他們呼吁開(kāi)展更多的相關(guān)研究，因?yàn)樵S多地方現(xiàn)在都面臨著氣溫上升的問(wèn)題。

閱讀理解：請(qǐng)?jiān)谧x完上文后，回答下列問(wèn)題。

1. In the study into the effects of heat on pregnant women and their unborn children, where were the women working?

2. In what ways did the extreme heat affect the unborn baby?

3. Why do scientists want more research into the effects of heat on unborn babies?

4. How many studies of the impact of extreme heat on pregnant women in low income countries have there been?

答案  

1. In the study into the effects of heat on pregnant women and their unborn children, where were the women working?
This study monitored pregnant women who were working in rice fields in The Gambia.

2. In what ways did the extreme heat affect the unborn baby?
Research found as the mother worked in the extreme heat the heart rate of the unborn child increased to dangerous levels. Blood flow to the foetus slowed as the placenta was impacted by the heat.

3. Why do scientists want more research into the effects of heat on unborn babies?
Scientists want more research as so many places now face rising temperatures.

4. How many studies of the impact of extreme heat on pregnant women in low income countries have there been?
This is the first real-world study looking at the impact of extreme heat on pregnant women in low-income countries.
