They ________ to enter the building by the back door; however, the front door was locked.
A．a(chǎn)re supposedB．a(chǎn)ren’t supposedC．weren’t supposedD．were supposed
C
考查短語：be supposed to do 應(yīng)該做某事，根據(jù)后半句the front door was locked.，可知前半句也應(yīng)用過去式，句意：他們不應(yīng)該通過后門進(jìn)入這個(gè)大樓，可是，前門鎖上了。根據(jù)句意應(yīng)選C。
