A. appears呈現(xiàn)；出現(xiàn)；一般現(xiàn)在時(shí)態(tài)；第三人稱單數(shù)；B. appeared呈現(xiàn)；出現(xiàn)；過去式；C. has appeared已經(jīng)出現(xiàn)，現(xiàn)在完成時(shí)；D. is appearing正在出現(xiàn)，現(xiàn)在進(jìn)行時(shí)。根據(jù)so far迄今為止，可知用現(xiàn)在完成時(shí)，其結(jié)構(gòu)是have/has done ,主語是單數(shù)，謂語動(dòng)詞變第三人稱單數(shù)。根據(jù)句意，故選C。

Not many years ago, some farmers were worried because hawks were taking many of their chickens. The farmers did not know what to do. Finally, they went to the officials and asked for help.

"Kill the hawks."the officials said we'll even pay you for them. So the farms began to think of ways to kill hawks.
