Tony decided to sell his horse Please Be True. He wrote to his friend Jimmy as follows:‘Dear JimmyI trust all is well with you old chap. Please Be True is for sale. The price is P7,000·00. If you are interested, come to the house with the money and you can take her away with you.’Jimmy received Tony’s letter and replied as follows:‘My good friend Tony, many thanks for the offer. I would dearly love to buy Please Be True. However P7,000·00 is rather too high a price for a horse. I will pay you P5,000·00 for her.’Tony did not reply to Jimmy’s letter.

阅读下面短文并回答问题，然后将答案写到答题卡相应的位置上（请注意问题后的词数要求）。

A 14-year-old girl was attacked by a grey bear while competing in a bike race. She managed to whisper the “bear” to her rescuer. The girl had serious head, neck and leg wounds. Now she is in a dangerous condition in hospital.

The girl was taking part in a 24-hour race through Bicentennial Park in Alaska when she was attacked by the bear. Bicentennial Park is next to Chugach State Park where some wild animals live.

The animal attacked the girl in a heavily wooded area at about 1:30 am. The girl called emergency services but she was unable to say any word. Another rider Peter Basinger found her lying unconscious on the ground. He told Anchorage Daily News that she managed to say the word “bear” when he stopped to help. Her helmet （头盔）had been knocked off in the attack and rolled into the woods. Mr Basinger waited with the girl for about 20 minutes until doctors arrived. Armed police travelled 3 km with doctors to pick up the girl.

Animal expert Rick Sinnot said something must be done as soon as possible to prevent the bear from attacking people again. “It was extremely terrifying,” he said.

Mr Sinnot told Anchorage Daily News that the bear might be a mother. It hurt two runners on a nearby path two weeks ago. He also said that the girl was lucky to have been wearing a bike helmet because the bear had bitten her head several times.

请编制程序，其功能是：内存中连续存放着20个无符号二进制字序列Xi(i＝1,2,…,20)，字的最高3位为000，此序列对应某一信号在一段时间内的连续变化，现对该信号进行一阶低通数字滤波，其滤波方程为：

Yi＝(15*Yi-1/16)+(Xi/16)，Y0＝0

Yi(i＝1,2…,20)为滤波后得到的新序列，结果存入内存。

例如：

内存中有01FFH,02FFH…

结果 001H,004DH…

部分程序已经给出，其中原始数据由过程LOAD从文件INPUT1.DAT中读入SOURCE开始的内存单元中，转换结果要求从RESULT开始存放，由过程SAVE保存到文件OUTPUT1.DAT中。

请填空BEGIN和END之间已经给出的一段源程序使其完整，需填空处已经用横线标出，每个空白一般只需要填一条指令或指令的一部分(指令助记符或操作数)，也可以填入功能相当的多条指令，或删去BEGIN和END之间原有的代码并自行编程来完成所要求的功能。对程序必须进行汇编，并与IO.OBJ链接产生可执行文件，最终运行程序产生结果。调试中若发现整个程序中存在错误之处，请加以修改。
