Scientists believe that by altering(A) the genetic composition of plants it is possible to develop specimens that are resisting(B) to disease(C) and have increased(D) food value.
选项:
a、altering
b、resisting
c、disease
d、have increased
d.have应改为has,因为它的主语是it,即to develop specimens这个动词不定式,主语是第三人称单数,故谓语动词应用三单形式.
