With the development of science, more new technology ______to the field of IT.
A．has introducedB．is being introducedC．is introducedD．was introduced
B
考查時(shí)態(tài)語(yǔ)態(tài)。句意為，隨著科學(xué)的發(fā)展，新的技術(shù)正在被引進(jìn)到IT領(lǐng)域。結(jié)合語(yǔ)境可知本句描述的是現(xiàn)在正在進(jìn)行的動(dòng)作，故用現(xiàn)在進(jìn)行時(shí)態(tài)。主語(yǔ)more new technology是動(dòng)作對(duì)象，故用被動(dòng)語(yǔ)態(tài)，選B。
