问题
Some bacteria______extremely harmful, but______are regularly used in producing cheeses, crackers and many other foods.
选项
A、is: the others
B、has been: the others
C、are: others
D、have been: others
答案
C
解析
句意:一些细菌极度有害,但其他的细菌通常被用来制作奶酪、饼干以及其他食品。bacteria为bacterium的复数形式,因此谓语应当用复数形式。该句陈述客观事实,使用一般现在时。“其他细菌”为泛指,不需要加定冠词。故选C。
