1. He flew a doctor to a Welsh village.______he has flown to many unusual places.
A.from then B.by then C.by that time D.since that time
解释：
from then 一般的用法应该是from then on。
by then :这个我不认同“问问团队☆居贤堂★”的说法，by then 的用法比比皆是，不过是用在将来完成时，如：Be married next Christmas, for you will have got your master's degree by then.明年圣诞结婚吧, 因为到那时你已经拿到硕士学位了。
by that time 到那时;节止那个时候 一般与过去完成时连用。
since that time 从那时起，仔细观察题干给的是has flown ，现在完成时，表示持续动作，意思是从那时开始，他已经载送乘客到过许多不寻常的地方。
所以选D。
2. The ploughed field is ready for______.
A.sewing B.sowing C.seeding D.growing
解释：
seed和sow都有播种的意思。
seed 一般作名词用，动词也是及物动词居多，做不及物动词时主要意思是结果。
而sow强调动作，可做不及物动词，并且这句也是一个习惯搭配。
选B。
3.The car park was deserted.It was______.
A.a desert B.empty C. abandoned D.wasted
解释：was deserted 是废弃的意思。联系上下文，因为停车场是废弃的，所以很空。
A是沙漠，C是被抛弃的，意思重复且无意义了,D浪费的，作为形容词使用，一般习惯用作定语，比如advice is wasted words.建议是多余的话。
B是空的，联系上下文，因为停车场是废弃的，所以很空，很顺其自然的表达。
所以选B。
1.A，因为后面句子是完成时，所以用时间段。
2 C，译为已经翻好的地准备播种。
3 C，ANANDONED，遗弃，废除。
1. He flew a doctor to a Welsh village.______he has flown to many unusual places.
A.from then B.by then C.by that time D.since that time
c by后边只能跟名词 代词 不能跟then等这种副词
2. The ploughed field is ready for______.
A.sewing B.sowing C.seeding D.growing
本题为句意理解题，ploughed field 是耕地的意思 C
3.The car park was deserted.It was______.
A.a desert B.empty C. abandoned D.wasted
同上，deserted意思是被遗弃 C
