請幫我改一下這一篇作文謝謝!!!
The TED that I watch is about the contribution to the madical .
An Indian student who graduated from MITbacked to his hometown , his friend , he is a doctor , told him that he helped a woman to have a baby , but the woman died . because of the woman have anemia caused a lot of bleeding .
He was worried about amemia can be completely healed why do people still die from anemia ? The reason is in his hometown , where clinics doesn't have device that test anemia .Because it is too expensive .
Thus , in order to result this problem . Last year ,he and his them invented a simple machine which is bloodless but can test anemia .They used three different wavelengths travel into the finger .These waves will measure oxyegn content 、protein content and the number of beats in twenty seconds .based on this information can determine anemia .
This simple machine will sell to clinic to poor people of the region to use .
This move not only made the medical improve but also is the benefit for all people .
No matter what issues , find it and result it and you will let the would much better ,no matter how small.
