Why are the red blood cells very important to people？
A．They deliver oxygen and nutrients to the rest of the body.
B．They kill the mosquitoes.
C．They are resistant to malaria.
D．They are nutrients.
参考答案
正确答案：A
解析：为什么红细胞对人们很重要?通过后文可以听出，疟疾之所以高致病主要是摧毁了人体中的红细胞。“Malaria rapidly destroys red blood cells, which deliver oxygen and nutrients to the rest of the body”，此句还交代了红细胞的作用在于向人类传送氧气和营养物质，所以a项符合题意。
