提示
關係代名詞 that 的先行詞是複數的 robots，子句動詞的單複數與語態（主動/被動）要跟著先行詞走。
正確答案
正解：C
詳解
A. is swimming...is fighting 用單數 be 動詞 is，與複數先行詞 robots 不一致。
B. swimming through your bloodstream and fighting diseases 缺少限定動詞，只有現在分詞，無法構成完整的關係子句。
C. swim through your bloodstream and fight diseases 為複數動詞原形，與先行詞 robots 一致，且為主動語態，符合句意，故為正解。
D. your bloodstream were swum and disease were fought 把子句寫成被動語態且主詞換成 your bloodstream/disease，與關係代名詞 that 應指代 robots 作主詞的結構不符。
