---- You haven’t got the textbook for my chemistry course yet.
---- I know, and we _____ to get it for the last 5 weeks.
A．will have been tryingB．have been trying
C．will be trying D．had tried
B
考查時態(tài)。由for the last 5 weeks可知用完成時，因此排除A、C，再由上文“你還沒有弄到化學(xué)教科書”，可以推測we一直到目前都在想辦法，因此用現(xiàn)在完成進(jìn)行時。for/in the last /past+段時間，常與完成時態(tài)連用，而in the past則用過去式。
