—I have got a headache.

—No wonder. You ________ in front of that computer too long.

A. work B. are working

C. worked D. have been working

 

D

【解析】

試題分析：句意：--我頭疼。--難怪。你一直在電腦面前工作那么長(zhǎng)時(shí)間。由I have got a headache可知用現(xiàn)在完成進(jìn)行時(shí)態(tài)，表示 過(guò)去開(kāi)始的動(dòng)作對(duì)現(xiàn)在造成的影響或結(jié)果。所以選D。

考點(diǎn): 考查時(shí)態(tài)

I relaxed my back to the seat and then I realized that toy gun in my body. Oh, God! I made a big mistake because it is gun forbidden area. I looked around and my eyes met with the guard’s eyes.
