A.to send B.for sending it C.to send it to D.for sending it to

答：第一题可能改自：
A computer does only what ( )people have it do.
A think B thinking C thought D to think
不然这个people前没必要加个定语.
A选项你打错了.是have it do.
A computer does only what thinking people ______.
A.have it do B.have it done C.have done it D.having it done
答：A.
译：计算机只做（正在思考的）人让它做的（事情）.
析：what引导名词性从句作does的宾语,连接代词what本身在从句中作do的宾语.
评：这个thinking作定语,句意很差,如不为考题（1）,没必要加,为本句之蛇足.
When I handed the report to John,he said that George was the person _______.
A.to send B.for sending it C.to send it to D.for sending it to
答：C
译：当我将那份报告递给约翰时,他说乔治才是这份报告该送交的人.
析：C项=.,.George was the person whom you should send it (=the report) to.
其实约翰想说的就是：You should have sent the report to George.或You should send the report to George.
也可以用强调句式：It is George that you should send the report to.
不定式作后置定语.不定式与被修饰的名词之前有逻辑上的动宾关系（send the report to him (the person)
John planned ____ around Europe on horseback,but his ambition has not been achieved till today.
A.to have traveled B.to travel C.traveling D.his traveling
本题设计有误.主要在but这个并列句.has not been achieved 说明到现在都没实现.
而till today则表示一个状态（或延续的动作）到今天就结束了,也就是今天约翰实现了他的骑马游欧洲的计划了!
另外,plan to do sth.plan (one's doing) sth.的用法都是可以的.
要选A则题目要改：
John planned to have traveled around Europe on horseback,but he was too busy.
=John had planned to travel around Europe on horseback,but he was too busy.
译：约翰本打算骑马游欧洲,可他太忙了.
